# multi-agent

Multi-clone architecture for running parallel Claude Code agents on the same repository with issue claiming, port allocation, and coordinated workflows.

## What This Module Does

Enables multiple Claude Code agents to work on the same repository simultaneously using independent git clones. Each agent runs in its own clone directory with full git isolation - independent branches, independent PRs, no conflicts.

> For **single-machine** parallel sub-agent delegation, the default isolation is a git worktree, not an extra clone (see the `git-worktrees` module). This multi-clone architecture is the heavier alternative — use it for persistent per-clone dev-server ports, hook-driven per-branch `tracking.csv`, long-lived independent agents, or cross-machine dispatch.

Key capabilities:

- **Parallel work**: Multiple agents work on different issues simultaneously
- **Issue claiming**: Agents claim issues via GitHub labels to avoid conflicts
- **Port allocation**: Dev server ports are offset per clone to prevent collisions
- **Coordination**: Cross-agent visibility via session logs
- **/mawf command**: Multi-Agent Workflow that takes unstructured feedback, splits it into issues, and spins up parallel agents

# Parallel Work Preference

When a task involves multiple independent issues or work items, prefer spawning parallel agents to complete them simultaneously. **On a single machine, isolate each agent in its own git worktree by default** (`isolation: "worktree"`): created per unit of work, torn down when that unit merges. Do **not** provision extra permanent clones just to get parallelism. Worktrees share the parent `.git` (no re-fetch), reclaim disk on teardown, and each has its own index and HEAD, so parallel builds and commits never collide. This is the default isolation for parallel sub-agent delegation — see `git-worktrees.md` and `subagent-patterns.md`.

**Reserve separate clones** for the cases a worktree cannot serve:
- Multiple long-lived independent agents each owning the repo for days
- Per-branch dev-server ports (worktrees share `.env`; clones get per-clone `.env.clone` with pre-computed `FRONTEND_PORT`/`BACKEND_PORT`)
- Hook-driven per-branch `tracking.csv` issue tracking that the multi-clone setup provides
- Cross-machine / cloud dispatch (a worktree cannot span machines)

**When to parallelize:**
- Multiple independent GitHub issues need to be completed
- A project has issues that do not block each other

**How (default, worktrees):** Launch agents with `isolation: "worktree"`; each works on its own feature branch off `origin/main` in an isolated worktree. Remove each worktree when its PR merges, and run `/worktree-sweep` as the orphan backstop.

**How (clones):** When one of the reserved cases applies and a multi-clone setup exists (workspace model: `~/code/{repo}-workspaces/`, or flat model: `~/code/{repo}-repos/`), launch agents pointed at different clone directories. Each agent claims its own issue via the tracking CSV (auto-registered by hooks on branch creation) and works independently. See `~/.claude/multi-agent-system.md` for the full coordination guide.

**Teardown is mandatory, not best-effort.** A worktree an agent built in does **not** auto-remove — remove each unit's worktree the moment its PR merges, and run `/worktree-sweep` to reclaim any orphans (including built-in `isolation:"worktree"` worktrees the harness could not auto-reclaim). Leaving built worktrees behind is exactly what filled 237 GB on one repo on 2026-07-13. See `git-worktrees.md`.

**Issue tracking**: Uses `~/code/{log-repo-name}/{repo}/tracking.csv`. Hooks auto-update tracking on branch creation, commits, PR creation, merge, and issue close. See `~/.claude/multi-agent-system.md` for details.

**Workspace model** (the heavier clone-based alternative, for the reserved cases above): Use `/workspace-setup {repo}` to create isolated workspace groups. Each workspace has 4 clones. Point a coordinator agent at a workspace directory - it discovers its clones and delegates. Prefer worktrees for ordinary single-machine parallel delegation; reach for the workspace model when you genuinely need persistent per-clone ports, per-branch `tracking.csv`, or long-lived independent agents.

**Cap peak concurrency.** Preferring parallelism does NOT mean launching everything at once. Too many heavy agents firing simultaneously - whether via the Workflow tool's `parallel()`/`pipeline()` or many Agent calls in one message - trips a server-side 429 throttle (`Server is temporarily limiting requests · Rate limited`) that fails the *entire* burst, not just the marginal agent. Keep simultaneous **heavy** agents (Opus, high/max effort, or large-context) to **4** (never exceed 5), launch in waves, and default fan-out agents to cheaper models / lower effort unless thoroughness is explicitly requested. If you have `subagent-patterns` installed, `concurrency-and-rate-limits.md` carries the full defaults table and the throttled-mid-run recovery procedure.

# Dev Server Port Allocation (Multi-Clone)

**Each clone gets isolated ports to prevent collisions.** Ports are assigned per-repo via `~/.claude/port-registry.json`, ensuring no collisions between different repos.

**How it works:**
- Each repo has a unique base port block (16 ports) in the registry
- Each clone's `.env.clone` has pre-computed `FRONTEND_PORT` and `BACKEND_PORT`
- A PreToolUse hook (`~/.claude/hooks/port-check.py`) warns about port mismatches and conflicts
- Read ports from `.env.clone`:
  ```bash
  FRONTEND_PORT=$(grep 'FRONTEND_PORT=' .env.clone | cut -d= -f2)
  BACKEND_PORT=$(grep 'BACKEND_PORT=' .env.clone | cut -d= -f2)
  pnpm dev -- --port ${FRONTEND_PORT}
  ```

**NEVER run `pnpm dev` or `wrangler dev` without clone-aware ports in a multi-clone repo.** Port collisions kill other agents' dev servers.

See `~/.claude/multi-agent-system.md` for full details.

# /mawf - Multi-Agent Workflow

Takes unstructured feedback, feature requests, or bug reports, splits them into discrete GitHub issues, and spins up parallel agents to implement them.

## Sub-Agent Model Optimization

When spawning execution agents to implement issues in Phase 5, set model to **sonnet** in the Agent tool call. Coding and implementation tasks work well on Sonnet. The orchestrator remains on the current model for issue parsing and agent coordination.

---

## Input

```
$ARGUMENTS
```

## Instructions

### Phase 1: Gather Feedback

If `$ARGUMENTS` contains the feedback directly, use it. Otherwise, prompt the user:

> "What feedback, feature requests, or bug reports do you want me to process? You can paste raw notes, bullet points, user feedback, or a mix of everything."

### Phase 2: Parse into Issues

Analyze the raw input and break it into discrete, independent work items. For each item:

1. **Identify the type**: feature, bug, refactor, chore, or human-agent
2. **Write a clear title**: Concise, actionable, imperative mood
3. **Write a description**: What needs to be done and why
4. **Assess dependencies**: Does this block or depend on other items?
5. **Assess scope**: Is this one PR or does it need to be an epic?

Present the parsed issue list to the user:

```
I've parsed your feedback into {N} issues:

1. [feature] {Title} - {one-line summary}
2. [bug] {Title} - {one-line summary}
3. [feature] {Title} - {one-line summary}
4. [human-agent] {Title} - {one-line summary}

Dependencies:
- Issue 3 depends on Issue 1
- Issue 4 requires human action (cannot be automated)

Does this look right? Should I adjust anything before creating these?
```

Wait for user confirmation before proceeding.

### Phase 2.5: Optional Context Research

When feedback references external issues, competitors, or community discussions, verify and enrich with real data before creating issues. This step is **optional** and should only run when feedback explicitly references external context. Skip entirely for purely internal feedback.

- **User references a competitor or product**: Search for it to add context to the issue description
  ```bash
  WebSearch "{product name} {feature mentioned}"
  ```

- **User references a bug others have reported**: Verify on GitHub or Reddit
  ```bash
  gh search issues "{error message or bug description}" --limit 5
  ```
  ```bash
  curl -s "https://www.reddit.com/search.json?q={error or issue}&limit=3" -H "User-Agent: research-agent/1.0" | jq '.data.children[].data | {title, url, score}'
  ```

- **User references a library or tool**: Check its current status
  ```bash
  gh repo view {owner}/{repo} --json isArchived,stargazerCount,pushedAt 2>/dev/null
  ```

Fold any findings into the relevant issue descriptions in Phase 3 (e.g., link to upstream issues, note competitor approaches, confirm library viability). Do not create separate issues for research findings.

### Phase 3: Create GitHub Issues

For each parsed item, create a GitHub issue:

```bash
gh issue create \
  --title "{title}" \
  --label "{type-label}" \
  --body "{structured body with summary, steps, and acceptance criteria}"
```

For items with dependencies, note the dependency in the issue body:

```markdown
## Dependencies
- Depends on #{dependency-issue-number}
```

For human-agent items:

```bash
gh issue create \
  --title "{title}" \
  --label "human-agent" \
  --body "{context, required actions, step-by-step instructions}"
```

Collect all created issue numbers.

### Phase 4: Plan Agent Allocation

**Isolation — worktrees by default.** Each parallel issue agent runs in its own **git worktree** (`isolation: "worktree"`) created from the current clone: ephemeral, sharing the parent `.git`, and torn down after its PR merges (Phase 5.3). The branch-creation tracking hook fires inside a worktree exactly as it does in a clone (worktrees share `.git/hooks`), so `tracking.csv` still works. Provision or reuse permanent clones only when the repo *already* has a multi-clone/workspace setup, or a specific need forces it (per-branch dev-server ports, multiple long-lived agents). See `git-worktrees.md`.

The clone discovery + occupancy checks below apply **only when reusing an existing multi-clone setup**; for the default worktree path, the concurrency cap (Phase 5.1) — not a fixed clone count — bounds the wave.

Determine how to allocate agents based on:

1. **Available clones** (only if reusing a multi-clone setup): Check how many clones exist
   ```bash
   # Detect model and discover clones
   WC_MATCH=$(basename "$PWD" | grep -oP 'w\d+-c\d+$')

   if [ -n "$WC_MATCH" ]; then
     # Workspace model: clones are siblings in the workspace dir
     WORKSPACE_DIR=$(dirname "$PWD")
     ls -d "${WORKSPACE_DIR}"/*-c[0-9]*/ 2>/dev/null | wc -l
   else
     # Flat clone model
     REPOS_DIR=$(dirname "$PWD")
     REPO_BASE=$(basename "$PWD" | sed 's/-[0-9]*$//')
     ls -d "${REPOS_DIR}/${REPO_BASE}"-[0-9]* 2>/dev/null | wc -l
   fi
   ```

**1b. Check for occupied clones**

After discovering clone directories, check which have active sessions:

```bash
python3 ~/.claude/lib/agent_sessions.py 2>/dev/null | python3 -c "
import json, sys
sessions = json.load(sys.stdin)
for s in sessions:
    if s.get('cwd'):
        print(s['cwd'])
" 2>/dev/null
```

Compare the output CWDs against the clone directories. Any clone directory that matches an active session CWD is **occupied** and should be excluded from assignment unless the user explicitly overrides.

In the execution plan presentation, mark occupied clones clearly:
```
Wave 1 (parallel):
  agent-w0-c0 (myrepo-w0-c0): #42 - Add dark mode toggle
  agent-w0-c1 (myrepo-w0-c1): #43 - Fix login redirect
  agent-w0-c2 (myrepo-w0-c2): [OCCUPIED - PID 78859, up 2h, branch: 166-api-native] - SKIPPED
  agent-w0-c3 (myrepo-w0-c3): #44 - Update onboarding flow
```

If all available clones are occupied, report this and ask the user:
> "All clones in this workspace are occupied by active sessions. Would you like to:
> 1. Wait for sessions to finish before proceeding
> 2. Proceed anyway (risk of conflict)
> 3. Cancel"

If agent_sessions.py is not available, skip this check and proceed normally.

2. **Issue dependencies**: Group into waves
   - **Wave 1**: Issues with no dependencies (can run in parallel)
   - **Wave 2**: Issues that depend on Wave 1 issues
   - **Wave N**: Issues that depend on Wave N-1 issues

3. **Agent assignment**: Map issues to clones
   - Skip human-agent issues (those are for the user)
   - Assign up to one issue per clone per wave
   - If more issues than clones, queue the extras for later waves

Present the execution plan (agent IDs match the clone directory names):

```
Execution Plan:

Wave 1 (parallel):
  {agent-id-0} ({clone-dir-0}): #{issue} - {title}
  {agent-id-1} ({clone-dir-1}): #{issue} - {title}
  {agent-id-2} ({clone-dir-2}): #{issue} - {title}

Wave 2 (after Wave 1):
  {agent-id-0} ({clone-dir-0}): #{issue} - {title}

Human tasks (for you):
  #{issue} - {title}

Proceed with execution?
```

Wait for user confirmation.

### Phase 5: Execute

For each wave:

#### 5.1 Spawn Agents

Use the Agent tool to launch one agent per assigned issue, each in its own **worktree** (`isolation: "worktree"`) by default — or its assigned clone directory when reusing a multi-clone setup (Phase 4):

> **Concurrency — avoid the 429 throttle.** With worktrees the wave is bounded by the concurrency cap; with clones it is bounded by the clone count. Execution agents run on `sonnet` (light), so a wave of up to ~8 is safe. If a wave has more units than that (or you escalate agents to a heavier model, cap 4), split into sub-waves. If a wave reports `Server is temporarily limiting requests · Rate limited`, wait 30–60s and re-launch only the failed issues. See `~/.claude/rules/concurrency-and-rate-limits.md`.

Each agent should:
1. Work in its own worktree (`isolation: "worktree"`) — or navigate to its assigned clone directory when reusing a multi-clone setup
2. Run `/startup` to initialize the session
3. Claim the issue by creating a branch (`git checkout -b {issue}-{desc} origin/main`). The PostToolUse hook auto-registers the claim in tracking.csv (it fires inside a worktree too).
4. Implement the work with tests
5. Run verification (lint, type-check, test, build)
6. Commit, push, and create a PR
7. Report completion

#### 5.2 Monitor Progress

Wait for all agents in the current wave to complete. Track:
- Which agents have finished
- Which PRs have been created
- Any failures that need attention

#### 5.3 Wave Completion

When all agents in a wave complete:
1. Review all PRs (check CI status)
2. Merge passing PRs: `gh pr merge --squash --delete-branch`
3. **Tear down each merged issue's worktree** (mandatory — a built-in worktree never auto-removes, and merged worktrees left behind are the leak that consumed 237 GB in the 2026-07-13 incident):
   ```bash
   git worktree remove <issue-worktree-path>   # non-force; branch + merged work survive removal
   git worktree prune
   ```
   Or run `/worktree-sweep` once after the wave to reclaim every merged worktree at once (it removes only clean ones, preserves any with unsaved work). Issues that ran in a reused clone are synced instead (next step), not removed.
4. Sync any reused clones to latest main:
   ```bash
   # Detect model and iterate clones
   WC_MATCH=$(basename "$PWD" | grep -oP 'w\d+-c\d+$')

   if [ -n "$WC_MATCH" ]; then
     # Workspace model
     WORKSPACE_DIR=$(dirname "$PWD")
     for dir in "${WORKSPACE_DIR}"/*-c[0-9]*/; do
       [ -d "$dir" ] || continue
       AGENT_ID=$(grep 'AGENT_ID=' "${dir}/.env.clone" 2>/dev/null | cut -d= -f2)
       git -C "$dir" fetch origin
       git -C "$dir" checkout "${AGENT_ID}" 2>/dev/null || git -C "$dir" checkout main
       git -C "$dir" reset --hard origin/main
     done
   else
     # Flat clone model
     REPOS_DIR=$(dirname "$PWD")
     REPO_BASE=$(basename "$PWD" | sed 's/-[0-9]*$//')
     for dir in ${REPOS_DIR}/${REPO_BASE}-[0-9]*; do
       AGENT_NUM=$(basename "$dir" | grep -oE '[0-9]+$')
       git -C "$dir" fetch origin
       git -C "$dir" checkout "agent-${AGENT_NUM}" 2>/dev/null || git -C "$dir" checkout main
       git -C "$dir" reset --hard origin/main
     done
   fi
   ```
5. Proceed to next wave

#### 5.4 Continue Until Complete

Repeat for each wave until all automatable issues are resolved. When all waves finish — or if the run exits early — run `/worktree-sweep` once as the teardown backstop, so no issue's worktree outlives the run (it removes only clean worktrees and preserves any with unsaved work). Teardown must not depend on every wave completing cleanly.

### Phase 6: Report

Present a final summary:

```

# /workspace-setup - Workspace Multi-Agent Setup

Use the Agent tool to execute this workflow on a cheaper model:

- **model**: sonnet
- **description**: workspace setup

Pass the agent all workflow instructions below. Include the received arguments: `$ARGUMENTS`

After the agent completes, relay its report to the user exactly as received.

---

Creates a workspace-based directory structure for parallel multi-agent development with full isolation between workspaces.

## Input

```
$ARGUMENTS
```

## Instructions

### Phase 1: Parse Arguments

Extract from `$ARGUMENTS`:
- **repo-name** (required): The GitHub repo name (e.g., `my-multi-word-repo`)
- **workspace-count** (optional, default: 3): Number of workspaces (w0 through wN-1)
- **clone-count** (optional, default: 4): Number of clones per workspace (c0 through cN-1)

If repo-name is missing, ask:

> "What GitHub repo should I set up workspaces for? (e.g., `my-multi-word-repo`)"

### Phase 2: Detect GitHub Info

```bash
# Detect GitHub username from git config or existing repos
GITHUB_USER=$(gh api user --jq '.login' 2>/dev/null)
echo "GitHub user: ${GITHUB_USER}"

# Verify repo exists
gh repo view "${GITHUB_USER}/${REPO_NAME}" --json name --jq '.name' 2>/dev/null
```

If the repo doesn't exist on GitHub, ask the user whether to create it or check the name.

### Phase 3: Check for Existing Setup

```bash
WORKSPACES_DIR="$HOME/code/${REPO_NAME}-workspaces"

if [ -d "$WORKSPACES_DIR" ]; then
  echo "WARNING: ${WORKSPACES_DIR} already exists"
  ls -d "${WORKSPACES_DIR}"/*/ 2>/dev/null
fi
```

If the directory exists and has content, ask the user before proceeding:

> "The directory `~/code/{repo}-workspaces/` already exists with content. Should I add new workspaces alongside existing ones, or start fresh?"

### Phase 4: Create Directory Structure and Clone

Create the full workspace structure:

```bash
REPO_NAME="{repo-name}"
GITHUB_USER="{github-user}"
WORKSPACE_COUNT={workspace-count}
CLONE_COUNT={clone-count}

WORKSPACES_DIR="$HOME/code/${REPO_NAME}-workspaces"
mkdir -p "$WORKSPACES_DIR"

for w in $(seq 0 $((WORKSPACE_COUNT - 1))); do
  WORKSPACE_DIR="${WORKSPACES_DIR}/${REPO_NAME}-w${w}"
  mkdir -p "$WORKSPACE_DIR"

  for c in $(seq 0 $((CLONE_COUNT - 1))); do
    CLONE_DIR="${WORKSPACE_DIR}/${REPO_NAME}-w${w}-c${c}"

    if [ -d "$CLONE_DIR" ]; then
      echo "SKIP: ${CLONE_DIR} already exists"
      continue
    fi

    echo "Cloning: ${CLONE_DIR}"
    git clone "git@github.com:${GITHUB_USER}/${REPO_NAME}.git" "$CLONE_DIR"

    # Create idle branch for this agent
    git -C "$CLONE_DIR" checkout -b "agent-w${w}-c${c}" origin/main

    # Look up base ports from port registry
    REGISTRY="$HOME/.claude/port-registry.json"
    if [ -f "$REGISTRY" ] && command -v python3 >/dev/null; then
      FRONTEND_BASE=$(python3 -c "import json; r=json.load(open('$REGISTRY')); print(r['repos'].get('${REPO_NAME}',{}).get('frontend',5173))" 2>/dev/null || echo 5173)
      BACKEND_BASE=$(python3 -c "import json; r=json.load(open('$REGISTRY')); print(r['repos'].get('${REPO_NAME}',{}).get('backend',8787))" 2>/dev/null || echo 8787)
    else
      FRONTEND_BASE=5173
      BACKEND_BASE=8787
    fi

    PORT_OFFSET=$((w * CLONE_COUNT + c))

    # Write .env.clone with workspace-aware identity and port assignments
    cat > "${CLONE_DIR}/.env.clone" << ENVEOF
# Auto-generated by workspace-setup. Do not edit.
WORKSPACE_NUMBER=${w}
CLONE_NUMBER=${c}
AGENT_ID=agent-w${w}-c${c}
PORT_OFFSET=${PORT_OFFSET}
FRONTEND_PORT=$((FRONTEND_BASE + PORT_OFFSET))
BACKEND_PORT=$((BACKEND_BASE + PORT_OFFSET))
ENVEOF

    echo "Created: ${CLONE_DIR} (agent-w${w}-c${c})"
  done
done
```

### Phase 5: Copy Environment Files

Check if any existing clone or the old `-repos` directory has env files to copy:

```bash
# Look for env files in old repos dir or first clone
OLD_REPOS_DIR="$HOME/code/${REPO_NAME}-repos"
ENV_SOURCE=""

if [ -d "$OLD_REPOS_DIR" ]; then
  FIRST_OLD=$(ls -d "${OLD_REPOS_DIR}/${REPO_NAME}-"[0-9]* 2>/dev/null | head -1)
  if [ -n "$FIRST_OLD" ]; then
    ENV_SOURCE="$FIRST_OLD"
  fi
fi

if [ -z "$ENV_SOURCE" ]; then
  # Check the first new clone for env files (in case this is a re-run)
  ENV_SOURCE="${WORKSPACES_DIR}/${REPO_NAME}-w0/${REPO_NAME}-w0-c0"
fi

if [ -n "$ENV_SOURCE" ]; then
  for f in "${ENV_SOURCE}"/.env*; do
    [ -f "$f" ] || continue
    FNAME=$(basename "$f")
    # Never copy .env.clone - each clone has its own
    [[ "$FNAME" == ".env.clone" ]] && continue
    echo "Copying ${FNAME} to all clones"
    for w in $(seq 0 $((WORKSPACE_COUNT - 1))); do
      for c in $(seq 0 $((CLONE_COUNT - 1))); do
        CLONE_DIR="${WORKSPACES_DIR}/${REPO_NAME}-w${w}/${REPO_NAME}-w${w}-c${c}"
        cp "$f" "${CLONE_DIR}/${FNAME}" 2>/dev/null
      done
    done
  done
fi
```

### Phase 6: Install Dependencies

```bash
# Check what package manager the project uses
FIRST_CLONE="${WORKSPACES_DIR}/${REPO_NAME}-w0/${REPO_NAME}-w0-c0"

if [ -f "${FIRST_CLONE}/pnpm-lock.yaml" ]; then
  PKG_MGR="pnpm"
elif [ -f "${FIRST_CLONE}/yarn.lock" ]; then

elif [ -f "${FIRST_CLONE}/package-lock.json" ] || [ -f "${FIRST_CLONE}/package.json" ]; then

fi

if [ -n "$PKG_MGR" ]; then
  echo "Installing dependencies with ${PKG_MGR} in all clones..."
  for w in $(seq 0 $((WORKSPACE_COUNT - 1))); do

      (cd "$CLONE_DIR" && ${PKG_MGR} install) 2>&1 | tail -1
    done
  done
fi
```

### Phase 7: Create GitHub Labels

Create workspace-aware agent labels on the repo:

```bash
# Color palette - workspace determines the hue family, clone determines shade
# w0: blues, w1: greens, w2: purples
W_PALETTES=(
  "0075ca 1d76db 5319e7 006b75"  # w0: blue family
  "0e8a16 2ea44f 3fb950 196c2e"  # w1: green family
  "8957e5 a371f7 d2a8ff 6e40c9"  # w2: purple family
  "d93f0b e4e669 fbca04 f9d0c4"  # w3: warm family (if needed)
)

for w in $(seq 0 $((WORKSPACE_COUNT - 1))); do
  COLORS=(${W_PALETTES[$w]})
  for c in $(seq 0 $((CLONE_COUNT - 1))); do
    COLOR="${COLORS[$c % ${#COLORS[@]}]}"
    LABEL="agent-w${w}-c${c}"
    gh label create "$LABEL" --color "$COLOR" \
      --description "Being worked on by ${LABEL} (workspace ${w}, clone ${c})" \
      2>/dev/null || echo "Label ${LABEL} already exists"
  done
done
```

### Phase 8: Ensure .env.clone is Gitignored

```bash
FIRST_CLONE="${WORKSPACES_DIR}/${REPO_NAME}-w0/${REPO_NAME}-w0-c0"
if ! grep -q "^\.env\.clone$" "${FIRST_CLONE}/.gitignore" 2>/dev/null; then
  echo ".env.clone" >> "${FIRST_CLONE}/.gitignore"
  echo "Added .env.clone to .gitignore"
fi
```

### Phase 9: Create Workspace CLAUDE.md

Each workspace directory gets a CLAUDE.md that tells the coordinator agent about the workspace system:

Create `{workspace-dir}/CLAUDE.md`:

```markdown
# Workspace {W} - {repo-name}

This is a workspace directory containing {clone-count} independent clones of the `{repo-name}` repository.

## Structure

| Clone | Directory | Agent ID | Port Offset |
|-------|-----------|----------|-------------|
| c0 | {repo}-w{W}-c0/ | agent-w{W}-c0 | {W*clone_count+0} |
| c1 | {repo}-w{W}-c1/ | agent-w{W}-c1 | {W*clone_count+1} |
| c2 | {repo}-w{W}-c2/ | agent-w{W}-c2 | {W*clone_count+2} |
| c3 | {repo}-w{W}-c3/ | agent-w{W}-c3 | {W*clone_count+3} |

## Coordinator Role

You are the coordinator agent for this workspace. You have exclusive access to the clones listed above. No other workspace agent will use these clones.

### Spawning Sub-Agents

When delegating work to sub-agents, point each at a specific clone directory within this workspace:

```bash
# Example: spawn agent in clone 0
cd {repo}-w{W}-c0/
```

Each sub-agent should:
1. Run `/startup` to initialize and check the tracking dashboard
2. Create a feature branch: `git checkout -b {issue}-{desc} origin/main` (the PostToolUse hook auto-registers the claim in tracking.csv)
3. Implement, test, commit, and create a PR
4. Report back

### Issue Tracking

- Claims are registered automatically in `{log-repo-name}/{repo}/tracking.csv` by the PostToolUse hook when a branch is created
- Check tracking state: `python3 ~/.claude/lib/agent_tracking.py list --repo {repo}`
- Each clone claims issues independently via branch creation

### Port Allocation

Frontend (Vite): `5173 + PORT_OFFSET`
Backend (Wrangler/API): `8787 + PORT_OFFSET`

Port offsets for this workspace: {W*clone_count} through {W*clone_count + clone_count - 1}

## Multi-Agent System

See `~/.claude/multi-agent-system.md` for the full coordination protocol.
```

### Phase 10: Set Up Log Directory

```bash
# Find the log repo
LOG_REPO=$(find "$HOME/code" -maxdepth 1 -name "*agent-logs" -type d | head -1)

if [ -n "$LOG_REPO" ]; then
  mkdir -p "${LOG_REPO}/${REPO_NAME}"
  echo "Log directory ready: ${LOG_REPO}/${REPO_NAME}/"

  # Commit the new directory
  cd "$LOG_REPO"
  git add -A
  if ! git diff --cached --quiet; then
    git commit -m "Add ${REPO_NAME} log directory for workspace setup"
    git pull --rebase && git push
  fi
fi
```

### Phase 11: Present Summary

Display the completed setup:

```
Workspace Setup Complete: {repo-name}

Directory: ~/code/{repo-name}-workspaces/

Workspaces: {workspace-count}
Clones per workspace: {clone-count}
Total clones: {workspace-count * clone-count}

Structure:
  {repo}-w0/
    {repo}-w0-c0/  (agent-w0-c0, ports: 5173+{0}/8787+{0})
    {repo}-w0-c1/  (agent-w0-c1, ports: 5173+{1}/8787+{1})
    {repo}-w0-c2/  (agent-w0-c2, ports: 5173+{2}/8787+{2})
    {repo}-w0-c3/  (agent-w0-c3, ports: 5173+{3}/8787+{3})
  {repo}-w1/
    {repo}-w1-c0/  (agent-w1-c0, ports: 5173+{4}/8787+{4})
    ...
  {repo}-w2/
    ...

Issue Tracking: ~/code/{log-repo-name}/{repo}/tracking.csv (auto-updated by hooks)

Usage:
  Point a coordinator agent at a workspace directory (e.g., ~/code/{repo}-workspaces/{repo}-w0/)
  The coordinator will discover its clones and delegate work to sub-agents.
  Each workspace is fully isolated - no coordination needed between workspaces.

# /handoff — Write a session handoff with copy-paste kickoff prompt

Write a structured markdown handoff to disk AND emit a copy-paste-ready kickoff prompt the next session can paste into a fresh Claude Code conversation. Solves the problem of context bloat: end a session before it degrades, paste the prompt into a new session, the next agent reads the handoff and picks up cleanly.

## Usage

```
/handoff                          Build the handoff from current session context
/handoff {one-line description}   Same, but seed the title
```

The skill is **always interactive**: you (the agent) gather the six sections from session context, write the file, and print the kickoff prompt verbatim. Do not skip sections — every one has a purpose. If a section genuinely has no content, write `(none)` and move on.

## When to use

- **End of a working session** that you don't want to resume via `claude --continue` (session is bloated, you're switching machines, you're going headless, etc.)
- **Mid-task context checkpoint** when `/compact` would lose too much. Write the handoff, `/clear`, paste the kickoff prompt back in.
- **Before a risky operation** — handoff acts as a known-good restore point.
- **End-of-day pause**. Resume tomorrow with the kickoff prompt.

Skip for trivial one-liner commits or work entirely inside throwaway experiments. For the peer-clone broadcast use case, the same `handoff.py` lib also feeds `/startup` auto-injection — you do not need a separate command.

## The six sections (in priority order)

A good handoff is one a fresh agent can read in under 2 minutes and act on within 5. Target 200-400 words total, never more. Use file:line anchors instead of pasted file contents.

1. **Current state** — One paragraph snapshot of where things are right now. Not a journal of what you did; a state read.
2. **Next steps** — Numbered, immediate, actionable. Item #1 is what the next agent should do first.
3. **Decisions & rationale** — What you chose AND why. Without rationale, the next agent can't judge edge cases.
4. **Files in progress** — `path:lineStart-lineEnd — state — one-line note`. States: `editing`, `partial`, `needs_review`, `ready`.
5. **Gotchas** — Anti-patterns you discovered, surprises, things that look right but aren't. The "if I forgot to tell you this, you'd waste an hour" section.
6. **Blockers** — What's stopping forward progress and what would unblock it. `(none)` if nothing.

## Implementation

Gather the six sections, then invoke the helper. Prefer the `--body` heredoc form for multi-line content (file lists, numbered next steps with sub-bullets):

```bash
python3 ~/.claude/lib/handoff.py write --body "$(cat <<'EOF'
# Handoff — <one-line description>

## Current state

<one paragraph>

## Next steps

1. <action>
2. <action>

## Decisions & rationale

- **<decision>**: <why> (`file:line` if relevant)

## Files in progress

- `path/to/file.ts:40-80` — editing — <note>

## Gotchas

<anti-patterns, surprises>

## Blockers

<what's stuck, or (none)>
EOF
)"
```

For single-line sections (a quick checkpoint), the per-section flags work too:

```bash
python3 ~/.claude/lib/handoff.py write \
  --title "Fix auth bug" \
  --state "..." --next "..." --decisions "..." \
  --files "..." --gotchas "..." --blockers "..."
```

The lib auto-detects repo, branch, agent (from `.env.clone`), PR, and issue. Pass `--repo`/`--agent` explicitly only when detection fails.

## Output contract

The CLI prints two things, in this order:

1. **Line 1**: absolute path to the new handoff file (script-safe, capturable via `head -n1`)
2. **Below the divider**: the copy-paste kickoff prompt — three sentences plus an optional `[USER DIRECTIVE]` slot

You (the agent) must show the user the **full output verbatim**, including the divider, so they can grab the prompt with a single triple-click or drag-select. Do not paraphrase, reformat, or wrap it in extra markdown.

Example:

```
~/.claude/handoffs/myrepo/2026-05-21T16-46-25-agent-w0-c0.md

Copy the prompt below into your next session:
----------------------------------------------------------------
Continue from session handoff at ~/.claude/handoffs/myrepo/2026-05-21T16-46-25-agent-w0-c0.md.

Read it completely before doing anything else. Trust the context it gives you — do not re-explore the codebase unless the handoff is wrong or incomplete. Then start with item #1 in "Next steps".

[USER DIRECTIVE: leave blank to let the agent propose the next action, or fill in to override]
----------------------------------------------------------------
```

Pass `--no-kickoff` only if you have a specific script-side reason; the default is always on.

## How it gets consumed

Two paths, both supported:

- **Copy-paste path (primary):** the user takes the kickoff prompt and pastes it as the first message in a fresh Claude Code session (same repo, different machine, or `claude -p` headless). The receiving agent reads the absolute path, opens the doc, and starts with item #1.
- **Auto-injection path (secondary):** if the user runs `/startup` in a new session in this clone, `startup-gather.sh` calls `handoff.py summary --include-self --max 3 --days 3` and surfaces recent handoffs (including peers') in the dashboard. This is the same lib feeding the same files; no second mechanism.

Handoffs older than 30 days are pruned on startup. Each handoff is timestamped — never overwrite; write a new one if you need to revise.

## Conventions

- One handoff per "unit of handed-off work" (typically one session-end). Multiple handoffs in the same session is fine.
- No secrets. Handoffs live unencrypted under `~/.claude/handoffs/`. Never include env vars, API keys, or API response bodies. File paths only.
- Keep it terse. Two sentences in a section beats six. The next agent has fresh context — they don't need a tutorial, they need a state read.

### lib

#!/usr/bin/env python3
"""
Multi-agent handoff storage lib.

Handoffs are short agent-authored markdown files that let sibling clones
see what a peer just finished without mining the full session transcript
(which is what `/recall` is for). They live locally under ~/.claude/handoffs
and are read on SessionStart by auto-startup.py.

Storage layout:
    ~/.claude/handoffs/
        {repo-slug}/
            {YYYY-MM-DD}T{HH-MM-SS}-{agent-id}.md

# Multi-Agent System

## Overview

Multiple Claude Code agents work on the same repository in parallel using independent clones.
Each agent runs in its own clone with full git isolation - independent branches, independent PRs.

> **Worktrees are the default isolation for parallel sub-agent delegation on one machine** (see `git-worktrees.md`). This multi-clone system is the heavier alternative — reach for it when you genuinely need persistent per-clone dev-server ports, hook-driven per-branch `tracking.csv`, multiple long-lived independent agents, or cross-machine dispatch. For ordinary "fan out N units across N agents on this machine," use worktrees (ephemeral, shared `.git`, torn down on merge) instead of provisioning permanent clones.

Two directory models are supported:

| Model | Directory Pattern | Agent Identity | Use Case |
|-------|-------------------|----------------|----------|
| **Flat clones** (legacy) | `~/code/{repo}-repos/{repo}-N/` | `agent-N` | Simple parallel work, no delegation |
| **Workspaces** (preferred) | `~/code/{repo}-workspaces/{repo}-wX/{repo}-wX-cY/` | `agent-wX-cY` | Delegated parallel work with isolation |

**Use workspaces when** a coordinator agent needs to spawn sub-agents without risk of overlapping with other coordinators. Use flat clones for simpler setups where a single human manages all agents directly.

---

## Workspace Model

### Directory Structure

```
~/code/{repo}-workspaces/
├── {repo}-w0/                    # Workspace 0 (coordinator agent pointed here)
│   ├── CLAUDE.md                 # Workspace-specific instructions
│   ├── {repo}-w0-c0/             # Clone 0 (agent-w0-c0)
│   ├── {repo}-w0-c1/             # Clone 1 (agent-w0-c1)
│   ├── {repo}-w0-c2/             # Clone 2 (agent-w0-c2)
│   └── {repo}-w0-c3/             # Clone 3 (agent-w0-c3)
├── {repo}-w1/                    # Workspace 1
│   ├── CLAUDE.md
│   ├── {repo}-w1-c0/
│   ├── {repo}-w1-c1/
│   ├── {repo}-w1-c2/
│   └── {repo}-w1-c3/
└── {repo}-w2/                    # Workspace 2
    ├── CLAUDE.md
    ├── {repo}-w2-c0/
    ├── {repo}-w2-c1/
    ├── {repo}-w2-c2/
    └── {repo}-w2-c3/
```

Each workspace is a fully isolated group of clones. A coordinator agent is pointed at a workspace directory and has exclusive access to the clones within it. No coordination is needed between workspaces.

### Setup

Use the `/workspace-setup` command:

```
/workspace-setup {repo-name}
```

This creates the full structure, clones, labels, env files, and installs dependencies. See `~/.claude/commands/workspace-setup.md` for details.

Defaults: 3 workspaces, 4 clones per workspace (12 total clones).

### Agent Identity (Workspaces)

Derived from the directory name pattern `{repo}-w{X}-c{Y}`:

```bash
AGENT_ID=$(basename "$PWD" | grep -oP 'w\d+-c\d+$' | sed 's/^/agent-/')
# myrepo-w1-c2 -> agent-w1-c2
```

| Directory | Agent ID |
|-----------|----------|
| `myrepo-w0-c0` | agent-w0-c0 |
| `myrepo-w0-c3` | agent-w0-c3 |
| `myrepo-w1-c0` | agent-w1-c0 |
| `myrepo-w2-c3` | agent-w2-c3 |

### .env.clone File (Workspaces)

Written automatically during workspace setup. Git-ignored. Contains:

```
# Auto-generated by workspace-setup. Do not edit.
WORKSPACE_NUMBER=1
CLONE_NUMBER=2
AGENT_ID=agent-w1-c2
PORT_OFFSET=6
```

### Agent Labels (Workspaces)

**Deprecated.** Agent labels (`agent-wX-cY`) on GitHub are no longer used for coordination. The tracking CSV (see "Issue Tracking System" section) is the sole source of truth for issue ownership. Historical agent labels may still exist on GitHub issues but are not maintained or checked.

### Claiming Issues (Workspaces)

1. **Check tracking CSV** - skip if already claimed by another agent:
   ```bash
   python3 ~/.claude/lib/agent_tracking.py list --repo {repo} --status claimed,in-progress,pr-created
   ```

2. **Check sibling clone branches** within your workspace:
   ```bash
   WORKSPACE_DIR=$(dirname "$PWD")
   for dir in "${WORKSPACE_DIR}"/*-c[0-9]*/; do
     [ -d "$dir" ] && [ "$dir" != "$PWD/" ] && \
       echo "$(basename $dir): $(git -C $dir branch --show-current 2>/dev/null)"
   done
   ```

3. **Create a branch** - the PostToolUse hook on `git checkout -b {N}-*` auto-registers the claim in the tracking CSV. No manual steps needed:
   ```bash
   git checkout -b {number}-{description} origin/main
   # Hook automatically writes to ~/code/{log-repo-name}/{repo}/tracking.csv
   ```

### Coordinator Role

The coordinator agent runs in the workspace directory (e.g., `~/code/myrepo-workspaces/myrepo-w0/`). It:

1. Receives a set of issues or a task from the human
2. Discovers available clones by listing subdirectories
3. Spawns sub-agents into specific clone directories using the Agent tool
4. Monitors progress and merges PRs
5. Reports back to the human

The coordinator does NOT write code directly. It delegates all implementation to sub-agents in clones.

### Git Workflow (Workspaces)

- **Branch from origin/main**: `git checkout -b {issue}-{desc} origin/main`
- **After PR merge**, return to idle:
  ```bash
  AGENT_ID=$(grep 'AGENT_ID=' .env.clone | cut -d= -f2)
  git fetch origin && git checkout "${AGENT_ID}" && git reset --hard origin/main && git branch -d {old-branch}
  ```
- **Each clone fetches independently** - run `git fetch origin` as needed
- **npm install is per-clone** - each has its own `node_modules/`
- `.env.clone` is unique per clone and must NOT be copied between clones

---

## Flat Clone Model (Legacy)

### Directory Structure

```
~/code/{repo}-repos/
├── {repo}-0/           # Clone 0 (agent-0)
├── {repo}-1/           # Clone 1 (agent-1)
├── {repo}-2/           # Clone 2 (agent-2)
├── {repo}-3/           # Clone 3 (agent-3)
└── {repo}-N/           # Additional clones as needed
```

Each clone is a full, independent git repository.

### Setup Commands

```bash
REPO="my-repo"
GITHUB_USER="your-username"
AGENT_COUNT=4  # Adjust as needed

mkdir -p ~/code/${REPO}-repos
for i in $(seq 0 $((AGENT_COUNT - 1))); do
  CLONE_DIR="$HOME/code/${REPO}-repos/${REPO}-${i}"
  git clone git@github.com:${GITHUB_USER}/${REPO}.git "$CLONE_DIR"
  git -C "$CLONE_DIR" checkout -b agent-${i} origin/main
  echo "# Auto-generated by clone setup. Do not edit.\nCLONE_NUMBER=${i}" > "$CLONE_DIR/.env.clone"
done
```

**Important**: Ensure `.env.clone` is in the project's `.gitignore`.

### Agent Labels (Flat)

**Deprecated.** Agent labels (`agent-N`) on GitHub are no longer used for coordination. The tracking CSV (see "Issue Tracking System" section) is the sole source of truth for issue ownership. Historical agent labels may still exist on GitHub issues but are not maintained or checked.

### Agent Identity (Flat)

Derived from the directory name's numeric suffix:

```bash
AGENT_NUM=$(basename "$PWD" | grep -oE '[0-9]+$' || echo "0")
AGENT_ID="agent-${AGENT_NUM}"
```

- `my-repo-0` or `my-repo` -> agent-0
- `my-repo-1` -> agent-1, etc.

### Adding an Agent to an Existing Flat Repo

To add a new agent (e.g., agent-4):

```bash
REPO="my-repo"
N=4  # New agent number
GITHUB_USER="your-username"
REPOS_DIR="$HOME/code/${REPO}-repos"
CLONE_DIR="${REPOS_DIR}/${REPO}-${N}"

# 1. Clone
git clone "git@github.com:${GITHUB_USER}/${REPO}.git" "$CLONE_DIR"

# 2. Create idle branch
git -C "$CLONE_DIR" checkout -b "agent-${N}" origin/main

# 3. Write clone number
echo "# Auto-generated by clone setup. Do not edit.\nCLONE_NUMBER=${N}" > "$CLONE_DIR/.env.clone"

# 4. Copy env files (excluding .env.clone)
for f in "${REPOS_DIR}/${REPO}-0"/.env*; do
  [ -f "$f" ] && [[ "$(basename "$f")" != ".env.clone" ]] && cp "$f" "$CLONE_DIR/"
done

# 5. Install dependencies
cd "$CLONE_DIR"
[ -f pnpm-lock.yaml ] && pnpm install
[ -f package-lock.json ] && npm install
```

### Claiming Issues (Flat)

1. **Check tracking CSV** - skip if already claimed by another agent:
   ```bash
   python3 ~/.claude/lib/agent_tracking.py list --repo {repo} --status claimed,in-progress,pr-created
   ```

2. **Check sibling clone branches**:
   ```bash
   for dir in $(find ~/code/{repo}-repos/ -maxdepth 1 -name "{repo}-[0-9]*" -type d 2>/dev/null); do
     echo "$(basename $dir): $(git -C $dir branch --show-current 2>/dev/null)"
   done
   ```

3. **Create a branch** - the PostToolUse hook on `git checkout -b {N}-*` auto-registers the claim in the tracking CSV. No manual steps needed:
   ```bash
   git checkout -b {number}-{description} origin/main
   # Hook automatically writes to ~/code/{log-repo-name}/{repo}/tracking.csv
   ```

---

## Unified Agent Identity Derivation

Use this logic to detect which model you're in and derive identity:

```bash
# Try workspace model first (directory name contains w{N}-c{M} pattern)
WC_MATCH=$(basename "$PWD" | grep -oP 'w\d+-c\d+$')

if [ -n "$WC_MATCH" ]; then
  # Workspace model
  AGENT_ID="agent-${WC_MATCH}"
else
  # Flat clone model (fallback)
  AGENT_NUM=$(basename "$PWD" | grep -oE '[0-9]+$' || echo "0")
  AGENT_ID="agent-${AGENT_NUM}"
fi

echo "Agent: ${AGENT_ID}"
```

Or read from `.env.clone` if available:

```bash
AGENT_ID=$(grep 'AGENT_ID=' .env.clone 2>/dev/null | cut -d= -f2)
if [ -z "$AGENT_ID" ]; then
  # Derive from directory name (see above)
fi
```

---

## Issue Tracking System

Issue ownership and status are tracked via a single CSV file per repo, replacing the previous GitHub label-based coordination system. The tracking CSV is the sole source of truth for which agent is working on which issue.

### Tracking File Location

```
~/code/{log-repo-name}/{repo}/tracking.csv
```

### CSV Schema

```
issue,agent,status,branch,pr,epic,title,claimed_at,updated_at
```

| Column | Description |
|--------|-------------|
| `issue` | GitHub issue number |
| `agent` | Agent identity (e.g., `agent-w0-c1`, `agent-2`) |
| `status` | Current status (see lifecycle below) |
| `branch` | Git branch name |
| `pr` | PR number (empty until PR is created) |
| `epic` | Epic issue number (empty if standalone) |
| `title` | Issue title (for human readability) |
| `claimed_at` | ISO timestamp when first claimed |
| `updated_at` | ISO timestamp of last status change |

### Status Lifecycle

```
claimed -> in-progress -> pr-created -> merged -> closed
```

| Status | Set by | Trigger |
|--------|--------|---------|
| `claimed` | PostToolUse hook | `git checkout -b {N}-*` |
| `in-progress` | PostToolUse hook | `git commit` (first commit on the branch) |
| `pr-created` | PostToolUse hook | `gh pr create` |
| `merged` | PostToolUse hook | `gh pr merge` |
| `closed` | PostToolUse hook | `gh issue close` |

### Automatic Hook Updates

Claude Code hooks automatically update the tracking CSV on these git/gh operations:

- **`git checkout -b {N}-*`** - Registers a new claim (status: `claimed`)
- **`git commit`** - Updates status to `in-progress` if currently `claimed`
- **`gh pr create`** - Updates status to `pr-created`, records PR number
- **`gh pr merge`** - Updates status to `merged`
- **`gh issue close`** - Updates status to `closed`

Agents do not need to manually update tracking. Just use standard git/gh commands and the hooks handle the rest.

### Concurrency

Multiple agents may update tracking.csv simultaneously. The tracking library uses standard git flow for concurrency:

```bash
cd ~/code/{log-repo-name} && git add -A && git commit -m "{agent-id}: tracking update" && git pull --rebase && git push
```

### Manual Tracking Commands

The tracking library at `~/.claude/lib/agent_tracking.py` can be used directly:

```bash
# List all tracked issues for a repo
python3 ~/.claude/lib/agent_tracking.py list --repo {repo}

# List only active issues (filter by status)
python3 ~/.claude/lib/agent_tracking.py list --repo {repo} --status claimed,in-progress,pr-created

# Import existing GitHub labels into tracking (migration from label-based system)
python3 ~/.claude/lib/agent_tracking.py import {repo}
```

### Stale Claim Detection

Use the `gc` command to detect and clean up stale claims (issues that were claimed but never progressed):

```bash
python3 ~/.claude/lib/agent_tracking.py gc --repo {repo}
```

---

## Dev Server Port Allocation

Each clone gets isolated ports to prevent collisions. Ports are assigned per-repo via a central registry, ensuring no collisions between different repos running simultaneously.

### Port Registry

`~/.claude/port-registry.json` assigns each repo a unique block of 16 ports per service type:

| Repo | Frontend Base | Backend Base |
|------|--------------|-------------|
| example-app | 5173 | 8787 |
| example-monorepo | 5189 | 8803 |
| ccgm | 5301 | 8915 |

The entries shipped in `port-registry.json` are examples — add a row per repo you run, keeping each repo's base ports at least 16 apart so blocks do not overlap.

Within each block, offset = `(workspace * clones_per_workspace) + clone` (workspace model) or `clone_number` (flat model).

### .env.clone Port Variables

Each clone's `.env.clone` includes pre-computed ports:

```
FRONTEND_PORT=5179   # base + offset, ready to use
BACKEND_PORT=8793
PORT_OFFSET=6        # raw offset if needed
```

### Using Ports

```bash
# Preferred: read pre-computed port from .env.clone
FRONTEND_PORT=$(grep 'FRONTEND_PORT=' .env.clone | cut -d= -f2)
BACKEND_PORT=$(grep 'BACKEND_PORT=' .env.clone | cut -d= -f2)

pnpm dev -- --port ${FRONTEND_PORT}
wrangler dev --port ${BACKEND_PORT}
```

Or if the project's dev config reads `.env.clone` automatically, just run `pnpm dev`.

### Port-Check Hook

A PreToolUse hook (`~/.claude/hooks/port-check.py`) automatically intercepts dev server commands and warns about:
- **Port mismatches** - command uses wrong port for this agent
- **Port conflicts** - target port is already in use (with PID)

The hook is advisory (warns, does not block). Agents should act on warnings.

### Playwright / E2E Testing

```bash
FRONTEND_PORT=$(grep 'FRONTEND_PORT=' .env.clone | cut -d= -f2)
BASE_URL="http://localhost:${FRONTEND_PORT}" npx playwright test
```

## When Finishing an Issue

The PostToolUse hooks handle tracking updates automatically:

- **`gh pr merge`** sets tracking status to `merged`
- **`gh issue close`** sets tracking status to `closed`

Just run the standard commands - no manual tracking updates needed:

```bash
# Merge the PR (hook updates tracking to "merged")
gh pr merge {pr-number} --squash

# Close the issue (hook updates tracking to "closed")
gh issue close {number} --comment "Completed: {summary}"
```

## Session Logs

All agents write to the agent log repo at `{log-repo-name}/{repo-name}/YYYYMMDD/{agent-id}.md`.

- Workspace model: `agent-w1-c2.md`
- Flat clone model: `agent-0.md`

Per-agent files = no merge conflicts. See `docs/session-memory.md` for how session memory and `/recall` work.

At session start, read other agents' logs in the same date subdirectory for cross-agent awareness.

## Conflict Resolution

If two agents accidentally claim the same issue:
1. The human supervisor resolves the conflict
2. One agent releases the issue (their tracking entry is updated to `closed`)
3. Work continues with clear ownership
