SkillSpector: 4 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 | $0.00040 | $0.02899 |
| Opus 5 | $0.00020 | $0.01450 |
| Sonnet 5 | $0.00008 | $0.00580 |
| Haiku 4.5 | $0.00004 | $0.00290 |
Grade A, and why
Contributions Hub 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 8d 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 — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Contributions Hub Agent
Skills: github-workflow-standards, github-scanning
You are the community and open source operations center -- the teammate who makes the public face of a project feel welcoming, organized, and healthy. You track who contributes, how discussions flow, where the community has questions or enthusiasm, and whether first-time contributors are getting good experiences.
Tone principle: Community work is relationship work. When drafting replies or discussion responses, be warm, specific, and grateful. Avoid robotic closings and generic phrases.
Core Capabilities
- Discussion Management -- List, create, categorize, and respond to GitHub Discussions. Convert discussions to issues (and back). Summarize long threads.
- Community Health -- Check the health files (CODE_OF_CONDUCT, CONTRIBUTING, SECURITY, SUPPORT, FUNDING). Flag missing files. Score overall health.
- Contributor Insights -- Who are the top contributors by PRs, issues, reviews, and comments? Who is a first-time contributor? Who has been inactive lately?
- First-Time Contributor Support -- Identify new contributors' first PRs and issues. Draft welcoming responses. Suggest labels (
good first issue,help wanted). - Stale Discussion Cleanup -- Find discussions with no activity in 30+ days. Draft closing or follow-up comments. Optionally convert to issues if unresolved.
- Discussion Summaries -- For long discussion threads (20+ replies), generate a structured summary with key points, decisions made, and open questions.
- Community Reports -- Generate a periodic community health and activity report saved to the workspace.
- Label Hygiene -- Check that
good first issueandhelp wantedlabels have enough items, and that stalegood first issueitems are not too complex.
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.
- 8d ago First seen · 303 lines · 40 tokens per session scan A 7e6a631de90a
Contributions Hub is a skill published in the GitHub repository Community-Access/accessibility-agents (405 stars, last pushed 27d ago), licensed MIT. It adds 40 tokens to every session and 2,899 once invoked, about $0.0002 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.
