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 | $0.00026 | $0.00697 |
| Opus 5.5 | $0.00010 | $0.00279 |
| Sonnet 5.5 | $0.00005 | $0.00139 |
| Haiku 4.5 | $0.00003 | $0.00070 |
Grade A, and why
skill-manager 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 1mo 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

skill-manager is an agent published in the GitHub repository f/prompts.chat (174,006 stars, last pushed yesterday), with no licence file. It adds 26 tokens to every session and 697 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other agents, from other repositories
playwright-capture
General-purpose Playwright screenshot agent. Auto-detects capture mode from inputs — section-centered viewport (show-off), element clip, or full page. Optional BGSOURCE triggers composite step (background photo + card overlay). Spawned by /show-off and any task needing screenshots.
plan-reviewer
Red-team reviewer for the /plan pipeline. Reads plan.md and phase files, then reviews for security gaps, hidden assumptions, failure modes, and scope creep — the plan equivalent of code-reviewer. Returns structured findings with ACCEPTED/NOTED verdicts.
planner
Plan-creation sub-agent for the /plan pipeline. Given a feature description and optional research reports, writes the full plan directory: plan.md overview + one phase-XX-{name}.md per phase. Used in Fast, Hard, Parallel, and Two modes.
tester
Testing sub-agent for the ck:test skill. Writes and runs tests for a resolved scope (default, unit/integration/e2e, verify, or TDD prepare/verify), and reports a structured PASSED/FAILED/REDREADY result. Never touches production code and never decides to call ck:fix — that is ck:test's call, not this agent's.
researcher
General-purpose research sub-agent. Given a topic and an assigned role, investigates one angle and returns a structured report. Spawned in parallel pairs (Primary + Alternative) by any pipeline needing option comparison. Budget ≤5 tool calls.
project-manager
Finalize sub-agent used by /cook and /fix. Syncs completed phase checkboxes in plan.md, updates plan Status, and reports overall progress. Skipped gracefully if no plan.md exists.
