The bash installer (`start.sh`) remains the canonical, full-fidelity path. ## What it ships | File | Purpose | |------|---------| | `lib/gen_marketplace.py` | Generator. Projects `modules/*/module.json` into `.claude-plugin/marketplace.json` + per-module `.claude-plugin/plugin.json`. Deterministic; `--check` for CI. | | `lib/validate_marketplace.py` | Dependency-free structural validator for the marketplace + every plugin manifest. CI fallback when the `claude` CLI is absent. | | `hooks/plugin-rule-inject.py` | SessionStart hook copied into every rules-bearing plugin. Injects that plugin's `rules/*.md` as `additionalContext` (opt-in via `CCGM_PLUGIN_RULE_INJECTION`). | | `rules/plugin-marketplace.md` | The rule explaining the two install paths and the generate-don't-hand-edit contract. | ## Why a marketplace projection Claude Code plugins ship commands, agents, skills, hooks, and output styles — but a plugin's `CLAUDE.md` is **not** loaded as context, and a plugin can only contribute the `agent`/`subagentStatusLine` settings keys. So: - **Commands / agents / skills / output styles** map cleanly to native plugin components. - **Rules** (`rules/*.md`), which the bash path auto-loads, are bridged by the SessionStart rule-injection hook. - **Deep `settings.json` merge + global `CLAUDE.md`** have no plugin equivalent — that is why the bash installer stays canonical. ## Usage ```bash # Regenerate after changing any module.json python3 modules/plugin-marketplace/lib/gen_marketplace.py # CI: fail if committed output drifted from module.json python3 modules/plugin-marketplace/lib/gen_marketplace.py --check # Validate (no claude CLI required) python3 modules/plugin-marketplace/lib/validate_marketplace.py # Validate with the real CLI when available claude plugin validate .claude-plugin/marketplace.json --strict ``` ## Installing CCGM as a marketplace (end user) ```bash claude plugin marketplace add lucasmccomb/ccgm claude plugin install code-quality@ccgm # rules behind a flag (opt-in, token cost): echo 'CCGM_PLUGIN_RULE_INJECTION=true' >> ~/.claude/.ccgm.env ``` ## Manual installation (without the CCGM installer) ```bash mkdir -p ~/.claude/lib ~/.claude/hooks ~/.claude/rules cp lib/gen_marketplace.py ~/.claude/lib/ cp lib/validate_marketplace.py ~/.claude/lib/ cp hooks/plugin-rule-inject.py ~/.claude/hooks/ cp rules/plugin-marketplace.md ~/.claude/rules/ ``` ## Status `beta` — maintainer/distribution tooling, opt-in via `start.sh --add plugin-marketplace`. Not bundled in any preset. ## Files ### rule #### rules/plugin-marketplace.md ```` # Plugin Marketplace CCGM can be installed two ways. They are not equivalent; pick deliberately. ## The two install paths | | Bash installer (`start.sh`) | Plugin marketplace | |---|---|---| | Canonical? | **Yes** — full fidelity | No — additive projection | | Deep `settings.json` merge | Yes | No (plugins ship only `agent`/`subagentStatusLine`) | | Global `CLAUDE.md` context | Yes (auto-loaded) | No (plugin `CLAUDE.md` is never auto-loaded) | | Rules (`rules/*.md`) | Auto-loaded by Claude Code | Injected by a SessionStart hook (opt-in) | | Commands / agents / skills | Installed to `~/.claude/` | Native plugin components | | Install command | `bash start.sh` | `claude plugin marketplace add /ccgm` (owner in README) | **When deep settings or always-on CLAUDE.md context matters, use the bash installer.** The marketplace path is for users who want CCGM's commands, agents, and skills delivered through Claude Code's native plugin manager, with rules available behind an opt-in flag. ## How the marketplace is produced The marketplace is **generated, never hand-maintained**. The source of truth is `modules/*/module.json`. The generator projects those manifests into: - `.claude-plugin/marketplace.json` — the catalog, one entry per module, via `metadata.pluginRoot: "./modules"`. - `modules//.claude-plugin/plugin.json` — one manifest per module. Run it after changing any `module.json`: ```bash python3 modules/plugin-marketplace/lib/gen_marketplace.py # write python3 modules/plugin-marketplace/lib/gen_marketplace.py --check # CI: fail if stale ``` The generator is deterministic (sorted output), so an unchanged tree produces byte-identical files. CI runs `--check` and fails if the committed output drifts from `module.json`. ## The CLAUDE.md / rules gap and the workaround A plugin's root `CLAUDE.md` is **not** loaded as context, and a plugin can only contribute the `agent` and `subagentStatusLine` settings keys. So a rules-only module (autonomy, code-quality, git-workflow, systematic-debugging, ...) would contribute nothing under the plugin path. The workaround: the generator wires a `SessionStart` hook into every rules-bearing plugin's `plugin.json`. The hook (`hooks/plugin-rule-inject.py`) reads that plugin's bundled `rules/*.md` and emits them as `additionalContext` at session start. It is **opt-in** — a strict no-op unless `CCGM_PLUGIN_RULE_INJECTION=true` is set in the environment or `~/.claude/.ccgm.env`, because injecting full rule bodies costs tokens. With the flag off, the plugin's commands/agents/skills still work natively. ## Validation - `claude plugin validate .claude-plugin/marketplace.json --strict` — validates the marketplace manifest when the Claude Code CLI is available. - `python3 modules/plugin-marketplace/lib/validate_marketplace.py` — dependency-free structural validation of the marketplace and every plugin manifest. CI runs this so the manifests stay valid even where `claude` is not installed. ## Rules of the road - **Never hand-edit `marketplace.json` or any `plugin.json`.** Edit `module.json` and re-run the generator. - **Never let the bash path regress** to accommodate the plugin path. The bash installer is canonical. - After adding or changing a module, run the generator and commit its output in the same change. ```` ### hook #### hooks/plugin-rule-inject.py ``` #!/usr/bin/env python3 """SessionStart hook: inject an installed plugin's bundled rules (issue #703). WHY THIS EXISTS --------------- When CCGM is installed via the native Claude Code plugin marketplace, a plugin's root CLAUDE.md is NOT loaded as context, and a plugin can only contribute the `agent`/`subagentStatusLine` settings keys. CCGM modules that are rules-only (autonomy, code-quality, git-workflow, systematic-debugging, ...) would therefore contribute nothing under the plugin path. This hook is the documented workaround: at fresh session start it reads the rules/*.md files bundled in THIS plugin (resolved via ${CLAUDE_PLUGIN_ROOT}) and emits them as `additionalContext`, so the plugin's guidance reaches Claude the same way the bash installer's ~/.claude/rules/ files do. The generator (gen_marketplace.py) copies this exact file into every rules-bearing plugin's hooks/ directory and wires the plugin.json SessionStart hook to call ${CLAUDE_PLUGIN_ROOT}/hooks/plugin-rule-inject.py. OPT-IN BY DEFAULT ----------------- Injecting full rule bodies costs tokens. To stay conservative and match the relevance-injection module's posture (issue #695), this hook is a strict NO-OP unless an explicit opt-in flag is set: CCGM_PLUGIN_RULE_INJECTION=true in ~/.claude/.ccgm.env (or the environment) With the flag unset, the plugin's commands/agents/skills still work natively; only the rule-body injection is suppressed. When the flag is set, the hook emits a header plus the concatenated rule files for this one plugin. SAFETY ------ - Fires only on source == "startup" (not resume/compact). - Never raises: any failure path returns without emitting, so it can never crash a session. - Reads only files inside ${CLAUDE_PLUGIN_ROOT}/rules/; no network, no writes.

WHAT THIS DOES -------------- CCGM's source of truth is `modules/*/module.json`. The bash installer (`start.sh`) is and remains the canonical, full-fidelity install path: only it performs the deep settings.json merge and writes the global CLAUDE.md context that Claude Code auto-loads. This generator ADDITIVELY projects the same modules into the native Claude Code plugin format so CCGM can also be consumed as a plugin marketplace (`claude plugin marketplace add /ccgm`; see the README for the owner). It is a pure projection: * It reads every `modules//module.json`. * It writes one `modules//.claude-plugin/plugin.json` per module, declaring the native plugin components that module actually ships. * It writes the catalog `.claude-plugin/marketplace.json` at the repo root, listing every module as a plugin (via `metadata.pluginRoot: "./modules"`). It NEVER edits module rule/command/agent/skill content. The only files it writes are the generated manifests and rule-hook copies, all of which are committed alongside this script. WHY EACH modules/ IS ITS OWN PLUGIN ROOT ---------------------------------------------- A CCGM module's on-disk layout already matches a plugin's expected layout: `commands/`, `agents/`, `skills/`, `output-styles/`, `hooks/`. So the plugin root is simply `modules//`, and `.claude-plugin/plugin.json` goes inside it. Plugins are copied to a cache on install and cannot reference files outside their own directory, so keeping each module self-rooted means every plugin is self-contained. THE CLAUDE.md / rules GAP ------------------------- A plugin's root `CLAUDE.md` is NOT loaded as context, and a plugin can only contribute the `agent`/`subagentStatusLine` settings keys. Many CCGM modules are rules-only (`rules/*.md`). To preserve their value under the plugin path, modules that ship `type:"rule"` files get a SessionStart hook (`hooks/plugin-rule-inject.py`) wired into their generated `plugin.json`. That hook injects the plugin's own bundled rules as `additionalContext` at session start. This is the documented workaround for plugin-CLAUDE.md-not-loading. DETERMINISM ----------- Output is fully sorted (modules, JSON keys) so re-running the generator on an unchanged tree produces byte-identical files. CI runs the generator with --check and fails if the working tree would change, guaranteeing the committed output stays in sync with module.json.
