Local-only OSS contribution command center with 41 deterministic gates against AI-slop failure modes. Helps maintainers triage contributor PRs, check for typical AI-generated patterns (over-engineering, false claims, fabricated tests, license violations), and approve / request-changes from a single dashboard.

Installation

Open Claude Code and run this command:

/plugin install contributing-clanker@claude-code-plugins-plus

Use --global to install for all projects, or --project for current project only.

What It Does

> Local-only OSS contribution command center. 41 deterministic gates against AI-slop failure modes.

A Claude Code plugin that turns /contribute into a discipline tool: every external action (claim, design issue, PR open, comment) passes through phase-appropriate gates that BLOCK or WARN on traps real maintainers complain about. Markdown-only state. No daemons. No SQLite. Filesystem is the tracker.

Contribute Command Center

Overview

Local-only OSS contribution workflow. The skill itself is the system — there is no separate CLI binary, dashboard, or cloud backend. State lives in three places:

GitHub itself — fetched live via gh for any PR/issue state question. Never cached long-term.
Markdown candidate files at ~/.contribute-system/candidates/issue.md — one per issue we're tracking. Frontmatter is the queryable layer (status, scoutscore, repo, researchpath, overrides). Body holds claim drafts, PR drafts, scope notes.
Markdown repo dossiers at ~/.contribute-system/research/__.md — one per upstream repo we contribute to. Built by the @researcher subagent. Frontmatter is canonical for every gate (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates). Body holds curated knowledge: pet peeves, failure log, free-form notes that survive refresh.
Append-only event log at ~/.contribute-system/log.jsonl — every gate run, transition attempt, override, scout/researcher invocation lands here with a UTC timestamp. Filterable via jq.

Use this skill when the user wants to:

Know what's in flight (open PRs, claimed issues, candidate queue)
Find a new issue to contribute to on GitHub
Build or refresh a per-repo dossier (delegates to @researcher)
Run gate-checked transitions (claim, work, submit) — every external action passes through transition.sh first
Draft a claim comment, Design Issue, or PR description (default: Design Issue, NOT a PR)
Run an upstream repo's test suite

The pre-2026-04-30 version of the skill used a SQLite tracker (~/.contribute-system/contribute.db, 32 tables) plus a separate contribute-system/ monorepo (Next.js dashboard, TS CLI, Cloud Functions). Both were deleted because they were never used in practice. The skill now reads markdown directly. That tradeoff is deliberate: human-readable, greppable, git-trackable, survives any tool, no daemon process.

Prerequisites

gh CLI, authenticated as the user (gh auth status should show "Logged in")
jq on PATH (used by gates + log filtering)
Workspace at ~/000-projects/contributing-clanker/ containing upstream clones (each clone has its own CLAUDE.md for project conventions)
Runtime state dir at ~/.contribute-system/ — created on first scout/researcher run if missing

Run this DCI check at activation (output is auto-injected into the prompt):

Restart Claude Code


gh: not logged in
gh auth login


jq: command not found
apt-get install jq (or equivalent for your platform)


Gate BLOCKs unexpectedly
Run audit-overrides.sh --gate= to see if it's a known false-positive cluster; override with --override-gate  "reason" if the BLOCK is wrong; submit a refinement to the source repo if the gate itself needs fixing


Dossier missing for a repo
First contribution to that repo; @researcher auto-builds on first transition


Stale dossier (>14 days)
Auto-refresh on next gate run; or @researcher refresh /


Want to disable one gate for one repo
