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.

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 | $0.00064 | $0.03775 |
| Opus 5 | $0.00032 | $0.01887 |
| Sonnet 5 | $0.00013 | $0.00755 |
| Haiku 4.5 | $0.00006 | $0.00378 |
Grade A, and why
open-source-contribution scanned grade A with 1 finding 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 12d 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- When adding install/service scripts, assume they may run as root. Validate all Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 377 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Open Source Contribution
Use this skill when helping a user publish, clean up, or contribute to an open-source repository. The default posture is conservative: protect privacy, preserve user work, keep the patch small, and prove the repository is safe to push.
Core Rules
- Never expose tokens, private keys, prompt logs, local transcripts, shell secrets, private service names, corporate/internal email addresses, or corporate identifiers (employee IDs, company usernames) as commit author names.
- Use a user-approved personal open-source email or GitHub noreply address for public commit authors and committers. Treat employer/corporate addresses as prohibited even when they are already configured globally or locally.
- Match the public author name to the GitHub account: use the GitHub login or
an approved display name. Treat a corporate ID configured as
user.nameas prohibited even when it is already configured globally or locally. - Treat Git commit metadata as public data. Secret scanners do not catch author and committer names/emails.
- Do not rewrite history unless the user explicitly allows it. If allowed, use force-with-lease and verify the remote head afterward.
- Do not push just to test. Push only when the user requested publish, ship, or PR update.
- When adding install/service scripts, assume they may run as root. Validate all user-controlled path/name inputs before interpolating them into filesystem paths or service manager commands.
- Run review after non-trivial changes. Treat review findings as advisory, then independently verify and fix only real, in-scope issues.
Secure Release Routing
When the task includes designing, migrating, or validating a registry or
GitHub release pipeline, use the secure-release skill for the release
protocol, runtime kit, ecosystem adapter, and rerun semantics. Keep this skill
for public-repository privacy, identity, security baseline, review, and push/PR
hygiene. Apply both sets of completion gates without copying the detailed
release protocol into this file.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-contribution is a skill published in the GitHub repository hxy91819/mason-skills (2 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 3,775 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
