Claude. Claude Debussy. 🎹
A Claude Code plugin marketplace from Oire: a small set of plugins for planning, review, documentation, and .NET work — plus an opt-in pack of opinionated Oire coding conventions. Packaged so both humans and Claude can navigate it, and so you can install just the pieces you want.

| Plugin | What it gives you | Install |
|---|---|---|
| planning | brainstorm, plan-make, plan-review, plan-exec | /plugin install planning@debussy |
| review | project-analyst (Nigel), project-audit | /plugin install review@debussy |
| write-manual | accessible user-manual pipeline | /plugin install write-manual@debussy |
| dotnet-tools | .NET style corrector | /plugin install dotnet-tools@debussy |
| conventions | opt-in convention hooks | /plugin install conventions@debussy |
Add the marketplace once, then install whichever you want:
/plugin marketplace add Oire/debussy
/plugin install planning@debussy
To try a plugin from a local checkout without publishing, point Claude Code at
the plugin directory: claude --plugin-dir plugins/planning (and /reload-plugins
inside a session picks up edits). Or add the whole local repo as a marketplace:
/plugin marketplace add <path-to-debussy>.
The idea-to-execution pipeline; the four components chain via the
docs/plans/<number>-<task>.md convention.
| Component | Trigger | Description |
|---|---|---|
brainstorm (skill) |
/planning:brainstorm, or "brainstorm", "help me design" |
One-question-at-a-time conversation that turns a rough idea into a validated design |
plan-make (command) |
/planning:plan-make |
Writes a structured implementation plan to docs/plans/ |
plan-review (agent) |
Task tool, or "review my plan" | Read-only review of a plan for completeness, correctness, and over-engineering before any code |
plan-exec (skill) |
/planning:plan-exec, or "execute plan" |
Executes the plan task by task in isolated subagents, leaving work uncommitted for review |
| Component | Trigger | Description |
|---|---|---|
project-analyst (agent, "Nigel") |
Task tool, or "what would a senior dev criticize?" | Holistic review of a project's polish, DX, docs, naming, packaging, and accessibility (WCAG 2.2 AA). Cross-stack |
project-audit (skill) |
/review:project-audit, or "audit the project" |
Two-reviewer release audit pairing Nigel with an external Codex code review; their findings deliberately barely overlap |
| Component | Trigger | Description |
|---|---|---|
write-manual (skill) |
/write-manual:write-manual, or "write manual" |
Multi-agent pipeline (Haiku scouts → Sonnet research → Opus writing → Sonnet verify/translate) producing accessible, WCAG 2.2 AA desktop-app user manuals |
| Component | Trigger | Description |
|---|---|---|
dotnet-style-corrector (agent) |
Task tool, or "check my C# style" | Checks C# against Oire .NET coding standards and .editorconfig. Stack-specific, hence its own plugin |
Opinionated Oire conventions enforced as PreToolUse hooks — organization
policy, not universal truths, so opt in only if you want them. (The other
plugins make no such assumptions and are meant for everyone.) When the plugin is
enabled, its hooks.json wires the two cross-platform hooks via bash; see
plugins/conventions/README.md for the full
story and the PowerShell/manual alternative.
| Hook | Fires on | Description |
|---|---|---|
check-american-english (cross-platform) |
Write/Edit/MultiEdit/NotebookEdit |
Blocks writes containing non-American spellings |
check-git-guard (cross-platform) |
Bash/PowerShell |
Blocks git commit/add/stage and git mv/git rm |
check-no-null-redirect (Windows-only) |
Bash/PowerShell |
Blocks null-device redirects that leave stray nul files. Shipped but not auto-wired (a plugin can't branch on OS); wire manually on Windows |
Installed plugins don't update themselves. To pull the latest from the marketplace, refresh the catalog and then update the plugin:
/plugin marketplace update debussy
/plugin update planning@debussy
Or enable auto-update for a plugin from the /plugin menu.
If you prefer the native PowerShell hook runners, or want the hooks
always-on without enabling the plugin, wire them through settings.json
instead:
- Run
install.ps1(Windows) orinstall.sh(Unix) to copy the hook scripts into~/.claude/hooks/. - Merge the matching snippet from
settings/into your~/.claude/settings.jsonunderhooks.PreToolUse, then restart Claude Code.
Windows + the plugin? If you enable the conventions plugin for the
cross-platform hooks and only need to add the Windows-only
check-no-null-redirect, you don't have to copy anything: wire a single
settings.json entry pointing straight at the plugin's own shipped script, so it
tracks marketplace auto-updates instead of drifting from a copy. Just don't also
wire the cross-platform PowerShell runners while the plugin is enabled, or
check-american-english and check-git-guard will fire twice. Full recipe in
plugins/conventions/hooks/README.md.
sync.* pulls in-place hook edits back into the repo; uninstall.* removes the
copied hooks (by name — it never touches your other hooks).
debussy is developed with its own conventions plugin enabled, so the repo
follows its own rules: American English everywhere, no null-device
redirects on Windows, and no Claude-side git commits/staging or
git mv/git rm. Documenting a
spelling checker means occasionally describing non-American spellings without
spelling them out — see the authoring notes in
plugins/conventions/hooks/README.md.
