oss-readiness

oss-readiness is a skill for Claude Code from JuanMarchetto/agent-skills. It costs 77 tokens per session (1,481 once invoked), scanned A, original, MIT.

An open-source readiness review that checks a project in five areas: licensing, documentation, security, community preparation, and public APIs.

In plain words
What is it for?
It is for auditing a project before open-sourcing it, including licenses, dependency risks, README and contribution guides, secrets, vulnerable dependencies, and API documentation.
Why use it?
It helps identify release blockers and prioritize fixes before making a codebase public.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

oss-readiness scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OSS Readiness — Open Source Readiness Evaluator

Evaluate whether your project is ready to be open-sourced. Five specialist agents audit your codebase simultaneously, then a synthesizer produces a unified readiness score with prioritized fixes sorted by severity.

How It Works

Input is a project path. Five agents scan the project in parallel:

  1. License Auditor (agents/license-auditor.md) — checks LICENSE file presence and type, dependency license compatibility (copyleft contamination in permissive projects), attribution requirements, patent clauses, files with conflicting license headers
  2. Documentation Reviewer (agents/docs-reviewer.md) — README completeness (description, install, usage, examples, badges), CONTRIBUTING.md quality, CHANGELOG.md presence, API documentation for libraries, code comment quality on public functions, quick-start guide
  3. Security Scanner (agents/security-scanner.md) — hardcoded secrets (API keys, tokens, passwords) in code, .env files not in .gitignore, secrets accidentally committed in git history, known vulnerable dependencies, debug/test credentials left in code, overly permissive file permissions
  4. Community Readiness (agents/community-readiness.md) — issue templates, PR templates, CODE_OF_CONDUCT.md, governance model, onboarding friction (steps from clone to running), labels/milestones setup, first-time contributor friendliness
  5. API Surface Analyzer (agents/api-surface-analyzer.md) — public API clearly defined (exports, public modules), semver compliance readiness, breaking change risk, backwards compatibility, type definitions/interfaces documented, deprecation policy

After all five agents complete, the Synthesizer (agents/synthesizer.md) combines their outputs into a unified assessment with weighted scoring, blocker identification, and a phased release plan if the project is not ready.

Usage

"Is my project ready to open source? ./my-project"
"Evaluate open source readiness for this repo"
"What do I need to fix before publishing this code?"
"Prepare ./my-library for public release"
"Open source checklist for this project"

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
