Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00169 | $0.13251 |
| Opus 5 | $0.00084 | $0.06626 |
| Sonnet 5 | $0.00034 | $0.02650 |
| Haiku 4.5 | $0.00017 | $0.01325 |
Grade A, and why
steel-quench 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 642 lines — stays where its author put it; the contents beside it link to each section on GitHub.
steel-quench — All-Angle Verification Meta-Skill
Heating steel and plunging it into water brings internal defects to the surface. quench-challenger attacks → defense → repeat = systematic surfacing and elimination of design flaws.
A designer's anxiety is most dangerous when vague. steel-quench breaks that anxiety into concrete attack angles, defends against them, and closes with residual risks explicitly stated.
Scope boundary: steel-quench stress-tests a near-complete artifact (post-build). For pre-build design decisions →
deliberation. For completed-asset validation →sim-conductor.
Trigger Phrases
| Phrase | Situation |
|---|---|
| "quench this", "run quench" | All-angle verification just before completion |
| "devil's judgment" | Focused challenger attack on specific design decision |
| "all-angle review", "end-to-end verification" | Full project scope verification |
| "shake out design anxiety", "deep pre-completion inspection" | Concretize vague anxiety |
| "attack from the root" | Re-verify from reason for existence |
| "diagnose with counterexample", "use this bad case as reference" | Phase 0 calibration |
| "did it really pass?", "re-attack after the gate", "the gate said PASS" | Wave-P3 gate-passage re-attack |
/steel-quench |
Explicit call |
Wave Structure
| Wave | Role | Termination |
|---|---|---|
| Phase 0 (optional) | Counterexample calibration — extract patterns from external bad cases, merge into Wave 1 (→ SKILL_detail.md §Phase0) |
No external case → skip |
| Wave 1 | Challenger attack (quench-challenger) — surface critical flaws, no defense | — |
| Wave 2 | Defense — defend or state as residual risk | — |
| Wave 3+ | Convergence — repeat until a round is clean AND triggers no repair | Zero new S/A and no repairs made in response, B included (§Convergence Criteria) |
| Wave 4 (optional) | Meta-Aware Adversary — AI uses its own nature as attack vector | Wave 3+ criterion (clean + no-repair) + AI-specific criteria |
| Wave-P3 (optional) | Gate-passage re-attack — when an upstream gate declares PASS, re-attack the just-passed artifact on Coverage / Narrative / False-confidence | All 3 dimensions Attack Failed |
| Wave 5 (optional) | Multi-Team Adversarial Panel — external CLIs or cross-session Claude | Wave 3+ criterion, cross-team |
| Wave-T (after convergence) | Temper — measure complexity the quench added; flag over-hardening | τ-PASS or named τ-FAIL |
What ships with it
1 file 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.

steel-quench is a skill published in the GitHub repository chrono-meta/forge-harness (14 stars, last pushed today), licensed MIT. It adds 169 tokens to every session and 13,251 once invoked, about $0.0008 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.

taiyi-review
A pre-merge review guide for checking code changes, design decisions, tests, and documentation. A merge adds reviewed changes to the main code branch.
review
Use when the user wants code assessed rather than changed — "review PR 88", "is this branch ready to merge?", "look over my changes", "any problems with this diff?", "give me a code review", "what do you think of this PR?", "sanity-check this branch", "ship it?". Applies to a pull request or the current branch when…
fix
PRFlow's code-review reception skill (formerly receiving-code-review), used by the review-and-fix loop and available directly. Use when addressing review feedback already posted on a pull request — verifying findings before applying them — as distinct from /prflow:review-and-fix, which runs the review itself and then…
review-and-fix
Use when the user wants problems in a pull request or the current branch both found AND corrected — "review my changes and fix what's wrong", "clean up whatever the review turns up", "address the review feedback on this branch", "tidy this PR up before merge", "find and fix the issues here". Requires explicit fix…
create-issue
Transitional alias — prefer /prflow:specs, which runs the same issue-drafting pipeline. Use when a rough user story, bug report, feature idea, piece of feedback, or an implementation plan should be recorded as a GitHub issue rather than built right now. This command name is retained so existing /prflow:create-issue…
docs-sync-internal
Use when code changes on the current branch need matching internal or developer documentation — "update our internal docs", "the architecture docs are stale after this change", "document what I just changed", "do the dev docs still match the code?" — or as a pre-push check that developer docs track the code. Narrower…
