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 | $0.00046 | $0.02857 |
| Opus 5 | $0.00023 | $0.01429 |
| Sonnet 5 | $0.00009 | $0.00571 |
| Haiku 4.5 | $0.00005 | $0.00286 |
Grade A, and why
issue-writing 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**Machine-authored is not the problem. Unreviewed is.** curl's security intake produced a slop crisis and, a year later, How it starts
The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Machine-authored is not the problem. Unreviewed is. curl's security intake produced a slop crisis and, a year later, its best confirmed-vulnerability rate in years — "somewhere in the 15-16% range" — while "almost every security report now uses AI to various degrees." The incentive, the platform, and the submitter population all changed together, so what fixed it is not identified; what the pair of measurements rules out is machine authorship as the cause. Maintainers object to reports nobody read before sending, not to the tool that drafted them. Never argue that the report is fine because a human would have written the same thing, and never soften a finding because a machine found it.
The elements maintainers want are the ones reporters find hardest to supply. A survey of 466 developers and users across Apache, Eclipse, and Mozilla found an information mismatch: steps to reproduce, stack traces, and test cases rank as most helpful to developers and most difficult for users to provide. That gap is where an agent is genuinely useful, because it can run the reproduction, capture the trace, and reduce the case. Spend the effort there rather than on prose.
A closed issue is not a fixed issue. Closure absorbs duplicates, wontfix, invalid, obsolete, and not-reproducible. Optimize for a maintainer being able to act, not for the issue being accepted.
Route the report before writing it
The channel decides the rules, and the wrong channel is a defect no quality of writing repairs.
- A suspected vulnerability never goes in the public tracker first. Disclosing it publicly is the harm. Find the private channel before writing anything down in public.
- A defect in observed behavior is a bug report, filed in the tracker under the project's template.
- A request for behavior that does not exist is a feature request, and it is judged on fit with project goals rather than on defect evidence.
- A question, a support request, or a usage problem is usually not an issue at all. Check whether the project routes these to discussions, a forum, or chat.
For a vulnerability, establish the current route by reading the project's own files, in this order: GitHub's private
vulnerability reporting if enabled on the repository, then SECURITY.md, then the project website's security page.
GitHub's documentation states that private vulnerability reporting "is separate from a repository's SECURITY.md file",
and that where it is enabled "anyone can submit a private vulnerability report to the repository maintainers."
Look the route up every time; never reuse a remembered one. curl moved four times inside a single year — bounty ended, reporting shifted to GitHub, GitHub was judged insufficient, reporting returned to HackerOne — and its policy now states that the project "cannot handle vulnerability reports sent to us over email." A route that was correct months ago is a guess.
What ships with it
5 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.

issue-writing is a skill published in the GitHub repository xobotyi/cc-foundry (20 stars, last pushed 3d ago), licensed MIT. It adds 46 tokens to every session and 2,857 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
