Ronce Racine

A personal Claude Code config, packaged so it installs into any repository and stays up to date there.

npx ronce-racine plan .      # read-only: what fits this repo, and why

It is a set of habits I use every day, written down once and shipped by a CLI:

• 13 rules, always on, injected by file type. The standing constraints an agent should never need to be reminded of.
• 36 skills, on demand. Procedures the agent loads when what you asked for matches, from modeling a domain to triaging a bug.
• 6 hooks (9 scripts), wired into settings.json for you. Small automatic behaviors on Claude Code events.
• 2 agents and 1 detection script, for the jobs that deserve their own context.

Not a framework and not a team product. One person's working setup, made installable so twelve repositories cannot quietly become twelve different configurations.

If you work across several repositories and keep telling Claude the same things, this should save you the repeating. If you are looking for a team standard to adopt wholesale, this is not one: take the parts you agree with.

Why it is packaged at all

Copy-pasted .claude/ config rots. You write a good rule in one project, paste it into the next two, improve it in the third, and six months later no two repositories agree. Nobody remembers which version came from where, and the CI agent works from a config nobody has read since the day it landed.

So the config is a package: an installer that proposes only what a project's stack justifies, a lockfile so a repository that drifts says so, and detach for the artifacts you customized on purpose.

Quickstart

npx ronce-racine plan .      # 1. read-only: what fits this repo, and why
npx ronce-racine install .   # 2. apply, then review the diff before committing

Nothing is written by plan. Here is a real run on a full-stack repository, abridged:

$ npx ronce-racine plan ./my-app
Analysis of ./my-app
Signals: git (.git/), ci (CI config), infra (Docker/infra), frontend (frontend dependencies), backend (Node backend dependencies), tests (E2E deps), code (sources detected)

✓ Recommended (installed by default):
  Rules (10) :
    • minimal-code - YAGNI + readability, any code project
    • secure-logging - GDPR: never log sensitive data
    • subscription-cleanup - frontend: subscription teardown
    • clean-architecture-deps - backend: dependency direction
    [... 6 more]
  Skills (23) :
    • recording-decisions - record non-obvious choices
    • commit-readiness-review - self-review before commit (+ scripts/precommit-scan.ts)
    • bug-triage-structured - full triage of a bug
    [... 20 more]
  Scripts (1) :
    • subscription-leak-scan.ts - detects subscriptions/listeners/timers without teardown
  Hooks (3) :
    • skill-reminder.ts - suggests the relevant skills for the prompt
    [... 2 more]
  Agents (2) :
    • code-reviewer - diff review agent
    • qa-tester - E2E testing agent

• Optional (add with --all):
  Rules (1) :
    • detection-gap-protocol - P0 found by user = detection failure
  Skills (12) :
    • audit-industrialisation - maturity audit orchestrator
    [... 11 more]
  Hooks (3) :
    • readme-freshness.ts - re-reads the README against what a push changes
    [... 2 more]

(The [... n more] lines mark where this transcript is abridged; a real run prints every entry, then the exact install command to copy.)

Then git add .claude && git commit: the config travels with the repository, so your teammates and your CI agent work from the same one you do.

The installer runs code on your machine and wires hooks into your settings.json. SECURITY.md says exactly what runs and when. Worth two minutes before you install anything, here or anywhere else.

Requirements: Node 18 or later in the target repo, and nothing else. Hooks ship pre-built, rules and skills are plain Markdown. Only the optional detection scripts need npx tsx.

What you get

Rules: the constraints that are always on

Rules are injected automatically based on the files in play, so they cost you nothing to remember. Each one exists because forgetting it produced a real defect.

Skills: the procedures, loaded on demand

There is nothing to type. Each skill's description carries trigger phrases, and the agent loads the one that matches what you asked for, in English or in French. Five that show the character of the set:

The full set, grouped by intention:

What each one is for, in full: docs/catalog.md.

Hooks: the small automatic behaviors

Every hook fails open: it runs on every session of every repository that installed it, so an error ends in a silent exit 0 rather than blocking you. The two to scrutinize before installing (worktree-env-setup symlinks your .env, the session-memo trio writes to disk) are documented in SECURITY.md.

Agents and scripts

• code-reviewer: architecture, reliability and correctness review of a diff. Read-only, and it ends on an actionable verdict.
• qa-tester: runs and writes E2E tests, favoring stable locators over timing hacks.
• subscription-leak-scan.ts: scans a staged frontend diff for subscriptions, listeners and timers with no teardown.

A project-specific agent or skill, coupled to your stack and your tracker, takes precedence over its generic version here. Every generic skill says so up front.

Why you should not trust the tables above

A skill nobody can trigger does not exist, and prose cannot be unit-tested. So two things are mechanical here rather than hoped for.

Routing is linted. Ten realistic sentences must reach the right skill ahead of the ones it is confusable with. When that lint was introduced, five of the ten failed, which is what a catalog looks like before anyone checks it.

Every skill is evaluated against a real agent run. Each carries an eval.yaml: a fixture, a realistic prompt, gates derived from its own exit conditions, and a judge for what stays subjective. It regularly says no.

What that costs and what else it caught: docs/quality-bar.md.

Staying in sync

npx ronce-racine check <repo>            # drift vs the canonical source
npx ronce-racine check <repo> --strict   # same, but fails CI
npx ronce-racine detach <repo> <token>   # exempt an artifact you customized on purpose

The lockfile records what was installed, check --strict turns drift into a failing job, and detach keeps a deliberate local customization from having to lie to the gate. Drop in the anti-drift CI job and the config can no longer rot silently.

Mechanics (the settings.json merge, the two distribution layers, the lockfile states): docs/distribution-model.md · docs/architecture.md.

Install options

The CLI (recommended)

npx ronce-racine plan    <repo>              # proposes, read-only
npx ronce-racine install <repo> [--all]      # applies (--all = + optionals)
npx ronce-racine install <repo> --rules-only # rules + lockfile only
npx ronce-racine check   <repo> [--strict]   # drift vs canonical (warns, or fails CI)
npx ronce-racine detach  <repo> <token>      # exempt a customized artifact from control
npx ronce-racine uninstall <repo> [--dry-run] # remove what it installed, nothing else

It copies into <repo>/.claude/ and merges the hook wirings into settings.json without disturbing what is already there. Full procedure: docs/adopting-a-repo.md.

Changed your mind? uninstall reverses it, driven by the lockfile so it removes what it installed and nothing else:

npx ronce-racine uninstall <repo> --dry-run   # what would go
npx ronce-racine uninstall <repo>             # remove it

It unwires its own hooks from settings.json and leaves the rest of that file alone, keeps anything you detached, and gives you back any file it overwrote on the way in.

Try it against throwaway repositories first with playground/setup.ts.

Or as a Claude Code plugin

/plugin marketplace add ChariereFiedler/ronce-racine
/plugin install ronce-racine@ronce-racine

The skills and the agents, subscribed rather than copied: they update when you update the plugin, and nothing lands in your repository. The rules, the hooks and the drift control are deliberately not in it, because always-on context and code that runs on your machine belong in a reviewed diff. Reasoning: docs/distribution-model.md.

Contributing

An artifact lives here only if it is truly generic: no crate, script, path or identifier tied to a project, no imposed tracker, no imposed stack. If a workflow is useful but coupled, split it: the generic protocol here, the tooled specifics in your own repository.

CONTRIBUTING.md for the bar and the workflow · docs/writing-a-rule.md · docs/writing-a-skill.md · docs/evaluating-skills.md · docs/developing.md for working on the toolkit itself · docs/decisions.md for why things are the way they are · AGENTS.md if you are the agent reading this.

The name

Ronce Racine is French for "bramble root", a plant that roots deep, spreads everywhere and refuses to die. A fitting name for a layer of engineering discipline meant to take hold in every repository, with just enough thorns to remind you it says "discipline".
