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 | $0.00107 | $0.00363 |
| Opus 5 | $0.00053 | $0.00181 |
| Sonnet 5 | $0.00021 | $0.00073 |
| Haiku 4.5 | $0.00011 | $0.00036 |
Grade A, and why
detect-github-url 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 10d 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.
What it actually says
Detect GitHub Skill Repository
The user has shared a GitHub URL. Recognize it and offer to browse its skills.
What to Do
-
Identify the GitHub URL from the user's message.
-
Respond naturally — acknowledge the link and explain you can browse available skills.
-
Offer to browse:
"I can check this repo for skills and show you what's available. Want me to take a look?"
-
When the user confirms, run
/skills-load <url>. This shows a numbered catalog — the user picks which skills to install as a plugin. -
If the URL doesn't look like a skills repo, still offer: "This might not contain Claude skills — want me to check anyway?"
Key Points
- Be conversational, not robotic
- The catalog-first approach means the user picks what they need — no bulk loading
- Selected skills get packaged as a
.pluginfile and presented with a "Save plugin" button for one-click installation into the/menu - Skills are also injected into the conversation for immediate use
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.

wrap-up
End-of-session handler that first checks whether the current session's plan is actually complete. If complete: run a quick retrospective, emit a forward-looking follow-up prompt, and — in a git repository — refresh the repo and clean gone branches. If incomplete: skip cleanup and emit ready-to-paste resume prompts so…
gh-cli-patterns
Canonical reference for all gh CLI command shapes used by skills in this plugin. Defines the placeholder convention, default-branch (trunk vs git-flow) detection, allowed --json fields, GraphQL fallback rules, -f/-F/--raw-field flag semantics, the PR-readiness gate, code-scanning alert query, review-thread…
session-status
Analyzes current session state without any cleanup. Full mode (default): resolves the active plan file, reads plan checklist + TaskList, gathers unfinished work/issues from conversation history, and emits a /handoff-built next-session prompt. Mid-session mode (/session-status mid): a fast plain-language 'done vs…
finalize-pr
Automatically finalize pull requests for merge by resolving CodeQL violations, review threads, merge conflicts, and CI failures. Handles single PR (current branch or by number), all open PRs in the repo, or all open PRs across the org. Includes bot-authored PRs in all modes.
ship
Commit, push, create PR(s), and auto-finalize — full automation pipeline. Handles uncommitted changes and recently created PRs.
