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 | $0.00034 | $0.00588 |
| Opus 5 | $0.00017 | $0.00294 |
| Sonnet 5 | $0.00007 | $0.00118 |
| Haiku 4.5 | $0.00003 | $0.00059 |
Grade A, and why
create-issue 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 yesterday.
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.

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.

create-issue is a skill published in the GitHub repository classroomio/classroomio (1,668 stars, last pushed yesterday), licensed AGPL-3.0. It adds 34 tokens to every session and 588 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.

work-issue
End-to-end GitHub issue workflow, repo-agnostic — read an issue, plan it, move it to In Progress on the project board (if one exists), implement it with efficient-fable orchestration, verify UI changes with a recorded GIF, open a template-compliant PR set to In Review with labels and milestone, and announce it on…

ship-pr
Take an implemented branch to a reviewable pull request — author a template-compliant PR body with a QA script, open it as a draft with labels/milestone/assignee mirrored from the issue, link it to the project board, flip it to ready only when it's genuinely reviewable, announce it on Slack with a reviewer mention (if…
gh-repo-config
Discover the current repo's GitHub-workflow facts — repo name, authenticated gh user, project board, PR template, Slack channel, branch/commit conventions, build/test commands — and cache the non-discoverable ones in /.claude/gh-workflow.config.json so they're asked at most once per repo. Use at the start of any…
issue-plan
Read a GitHub issue and produce a posted plan of attack — gather the issue with its comments and references, survey the code it touches (read-only), author a short plan (root cause, approach, risks, test plan), then assign the issue, move it to In Progress on the board (if configured), and post the plan as the issue…
