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 | $0.00000 | $0.00882 |
| Opus 5 | $0.00000 | $0.00441 |
| Sonnet 5 | $0.00000 | $0.00176 |
| Haiku 4.5 | $0.00000 | $0.00088 |
Grade A, and why
critic-apply 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 6d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: critic-apply description: >- Rule-based application of a converged critic sheet: accept every convergent target (2+ critics), skip split panels, decline constitution-protected spans with cause, prefer the omission when remedies conflict, and count reverse-outline cheap ranks as convergence for single-critic deletions. Rewrites route through the rewrite transport with a narrow one-sentence instruction and a mechanical gate (numbers, citations, em-dash/colon budgets, size band); deletions apply directly; rst markers round-trip. Reports applied/kept/declined-by-rule for the generation: block. Triggers: critic apply, apply the critic sheet, apply the panel, apply suggestions by rule, converged sheet application. argument-hint: '--article <draft.md> --sheet .critic-sheet.md'
Critic Apply (rule-based sheet application)
critic-panel produces the sheet and never applies anything; the author used to pick by hand, and the auto-application policy (operator, 2026-09-01) ran twice as throwaway scratchpad scripts. This skill is that policy as versioned code: the author never reads drivel because the rules decide, and the rules are arguable because they are deterministic.
The rules
| rule | effect |
|---|---|
| convergent target (2+ distinct critics on one passage) | accepted |
| split panel (a proposal beside a KEEP/NO CHANGE dissent) | skipped — proposal + dissent is not convergence |
constitution-protected span (--protected verbatim spans) |
declined with cause, however many critics want it — the constitution outranks the panel |
| remedy conflict inside a convergence, one remedy a CUT | the omission wins — a deletion authors no prose |
single-critic CUT on a paragraph reverse-outline ranked cheap (--cheap-paragraphs) |
accepted — cross-instrument agreement counts as convergence for deletions |
| any other single-critic finding | skipped; the author picks those by hand |
What ships with it
2 files 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.

critic-apply is a skill published in the GitHub repository petar-djukic/writing-skills (4 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 882 tokens. 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 2026-09-05.
