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 | $0.22268 | $0.22268 |
| Opus 5 | $0.11134 | $0.11134 |
| Sonnet 5 | $0.04454 | $0.04454 |
| Haiku 4.5 | $0.02227 | $0.02227 |
Grade C, and why
agent-skills CLAUDE.md scanned grade C 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 today.
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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- `pr-reviewer` — unified PR reviewer — handles both own-work (self relation) and cross-review (cross relation) via `REVIEW_RELATION` set at Step 0.5. The pipeline is identical in both relations — same findings, same gat How it starts

Agent Skills
Audience
The skills and agents in this repository are consumed operationally by agentic frameworks (AI coding agents, copilots, and autonomous developer tools). Every piece of guidance must be written so that an agent can act on it without human interpretation.
When writing or editing content, follow these principles:
- Be prescriptive, not descriptive. Tell the agent what to do, not explain concepts.
- Make decisions enumerable. Provide numbered decision processes, lookup tables, or explicit criteria.
- Include code examples for every actionable rule. Show both correct and incorrect patterns.
- Avoid subjective conditions. State concrete, testable criteria.
- Keep rules self-contained. Each file must make sense on its own.
Repository Structure
Skills live in skills/<category>/<name>/SKILL.md across 7 categories.
Agents live in agents/ since they need their own model and tool configuration.
Type markers (by primary entry point — all three are technically model-invocable via the Skill() tool when disable-model-invocation: false): auto = description aggressively auto-triggers on natural language; / = primary entry is the slash command, description does not auto-trigger; Skill() = primary entry is being called by another skill / workflow.
workflow/ — end-to-end orchestrators
autonomous-workflow(auto) — phase-based feature delivery 0–7. Opt-inawdispatcher detects tier (Micro/Lite/Full) and routes single-pass vs the planner→executor split (Full only). Two-tier self-improvement hoisted to the dispatcher (universal): fast episodic-lessons tier (LoreKitloop::aw-lessons) promotes to the gateddiagnoseslow tier atseen_count ≥ 3.

Research basis:references/planning-quality-research.md.

Self-improvement:fix-bug-lessonsfast tier (read Phase 0.5 / write Phase 5·7·8) for its diagnostic phases; inheritsaw-lessonsviaaw-executor; promotes todiagnoseimplement-suggestion(/) — apply reviewer suggestions across PRs; per-comment/critical+/confidencevalidation.--watchloops the apply on a single PR (wait for new bot/human comments → apply → push, max 5 iterations) — the loopcreate-prdispatches post-push. Rule:watch-mode.md.--resolve-all(opt-in, passed byreview-loop) adds a worker pass that replies-to-and-resolves the non-fix threads it can honestly close (answersquestion, records the agent's take ondiscussion, gives a decline rationale for gated-out changes) so the PR converges to zero open threads — only genuine human-judgment flags stay open (never green-washes a live finding; same invariant asthread-resolution.md). Self-improvement:implement-suggestion-lessonsfast tier (read Phase 3 / write Phase 7 + watch re-flag) for its own classification, gate-calibration, and lane-selection decisions; standard-lane inheritsaw-lessonsviaaw-planner; promotes todiagnose. Dual outcome producer: at Phase 7 and per-iteration inside--watch, emits (1) fingerprinted outcome records to thereview-outcomescandidate/outcome bus (seeagents/shared/rules/review-outcomes.md) — feedoutcome-learning.md's promotion decisions; and (2) per-comment relevance signals to thereviewer-comment-relevanceLoreKit bucket (tagloop::reviewer-comment-relevance, seeagents/shared/rules/comment-relevance-memory.md) — read on everypr-reviewerrun to suppress recurring noise and reinforce reliably-resolved patterns, making the pipeline continuously more accurate per repository. CI boundary: never fixes CI. The worker's Phase 6 pre-push gate now runs a full, unscoped fast-check pass over the whole repo before the single push (step 3.5) — per-comment checks are scoped to touched files and cannot see a consumer the edit broke elsewhere — and hard-STOPs with the batch local-only on failure. Under--watch, post-push check state is read only as a stop reason (ci red — <checks>); noci-auto-fixdispatch, no budget spent. Composing apply-and-get-green isreview-loop's job.
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.

agent-skills CLAUDE.md is an instructions file published in the GitHub repository mthines/agent-skills (12 stars, last pushed yesterday), licensed MIT. It adds 22,268 tokens to every session, about $0.1113 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
