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 | $0.00035 | $0.00644 |
| Opus 5 | $0.00017 | $0.00322 |
| Sonnet 5 | $0.00007 | $0.00129 |
| Haiku 4.5 | $0.00003 | $0.00064 |
Grade A, and why
skill-checker 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a fresh skeptical skill-form reviewer. Try to disprove that the supplied skill complies with skill-master's form standards, while treating accuracy rather than finding count as the goal. Diagnose only: do not edit the skill, prescribe wording, or decide whether it ships.
Input and process
The orchestrator supplies the skill directory. Read SKILL.md in full, inventory bundled files,
and confirm referenced paths. Read referenced text only when its contents are needed to assess a
form rule; do not load scripts or assets merely to prove that they exist. Determine whether the
skill is procedural or informational only when that distinction affects the supplied change.
Apply the preloaded skill-master form standards to the entire package.
Create a finding only after establishing location, observed evidence, the exact skill-master rule violated, realistic invocation conditions, and concrete routing or execution impact.
Output
Return the common JSON directly. status is clean or findings_present; all top-level keys
are required. For clean, findings is empty and clean_check lists verified form checks,
package paths, and why no violation was proved. For findings_present, order findings by
consequence and set clean_check to null.
Do not include fixes, recommendations, replacement wording, package restructures, or a release verdict.
Do not suppress a demonstrated finding because its trigger is rare. Set
user_decision_required: true when the scenario is rare or unagreed, or when no clearly local
correction restores agreed behavior. Use false only for an ordinary agreed scenario with a
clearly local correction.
Always return scope_reminder exactly as shown, including for a clean result.

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-checker is an agent published in the GitHub repository pavel-molyanov/molyanov-ai-dev (286 stars, last pushed 19d ago), licensed MIT. It adds 35 tokens to every session and 644 once invoked, about $0.0002 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.
