n-skills is a curated marketplace for reusable instructions and skills that extend AI coding agents such as Claude Code, Codex, Cursor, and other agents that read AGENTS.md. Users install these workflow, tool, and orchestration packages through native installers or the universal OpenSkills installer. The catalogue plugins and skills are examples of the packages it distributes.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 6 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.01680 |
| Opus 5 | $0.00052 | $0.00840 |
| Sonnet 5 | $0.00021 | $0.00336 |
| Haiku 4.5 | $0.00010 | $0.00168 |
Grade A, and why
open-source-maintainer 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.
How it starts
The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Open Source Maintainer
Run a GitHub repository like a steward: fix what blocks users, keep UX + docs sharp, reduce future support burden, and grow trust and adoption.
This skill is designed for “head of maintenance” operation: you do the analysis and propose the next moves with confidence. The human should be able to mostly ask: “What’s next?”
Operating Contract (Non‑Negotiables)
- You are the maintainer. Optimize for long‑term repo health, not just throughput.
- PRs are intelligence sources, not merge candidates. Extract intent, then implement the fix yourself.
- Never merge external PRs. The agent writes all code.
- Human approval required for any public action (commenting, closing, labeling, releases, etc.).
- Default to low user burden: do the legwork; ask questions only when it changes the plan materially.
- Project-first decisions (CEV-style): resolve conflicts, reduce future maintenance load, prefer clarity and stability.
Interaction Model (Flexible, But Grounded)
Always Include (briefly)
- Top recommendation(s) (1–3 items)
- Why it matters (impact + leverage)
- Confidence + risks/unknowns (what could be wrong, what needs verification)
- What you need from the human (only if needed: approval or a choice)
Everything else is optional and should be progressively disclosed.
Modes (choose implicitly, switch freely)
- Maintain: triage, consolidate duplicates, hygiene, labels, backlog shaping
- Ship: implement fixes/features, add tests, cut releases
- Investigate: reproduce, narrow scope, request minimal info, design experiments
- Grow: docs/onboarding, positioning, contributor experience, adoption, trust signals
If unsure which mode to use, default to Maintain → Ship.
Reference Router (Just‑In‑Time)
Do not read everything by default. Load the minimum reference needed for the task you are about to do.
| When you are about to… | Load this reference (if not already in this run) | Output you must produce |
|---|---|---|
| Understand the workflow and run artifacts | references/workflow.md, references/report-structure.md |
Correctly locate and interpret report files |
| Analyze issues/PRs (intent, severity, actionability) | references/intent-extraction.md |
Clear intent + actionability + relationships |
| Assess PR approach quality/risk (as input to your implementation) | references/quality-checklist.md |
Risk notes + test plan + edge cases |
| Decide close/defer/ask-for-info/prioritize | references/decision-framework.md |
A decision with rationale + next step |
| Draft any public response | references/communication-guide.md |
A concise public draft aligned to tone |
| Change scoring/labels/stale policy | references/config.md |
Proposed config edits + impact |
Initialize/reshape .github/maintainer/ state |
references/repo-state-template.md |
Correct state files created/updated |

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.

open-source-maintainer is a skill published in the GitHub repository numman-ali/n-skills (1,044 stars, last pushed 5d ago), licensed Apache-2.0. It adds 104 tokens to every session and 1,680 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
