SkillSpector: 1 finding, 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 →
- medium Rogue Agent · line 18 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00127 | $0.02243 |
| Opus 5 | $0.00063 | $0.01122 |
| Sonnet 5 | $0.00025 | $0.00449 |
| Haiku 4.5 | $0.00013 | $0.00224 |
Grade A, and why
documentation-writing 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 — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Management
Create and maintain .claude/skills/project-knowledge/ from the evidence source the user named.
Outside Feature Finalization Mode, follow create-project-knowledge.md when the user starts or continues initial documentation and either its interview is still in progress or Project Knowledge is missing, still a template, or only partially filled. Apply project-knowledge-structures.md for content ownership and structure. After writing, run the manual sync and continue at Documentation Review.
When the user explicitly asks to reorganize existing Project Knowledge, apply project-knowledge-structures.md. Ordinary updates preserve the filled structure already in use.
Manual Project Documentation Sync
Project documentation source of truth is Claude-side: CLAUDE.md and .claude/**.
Codex-side AGENTS.md and .codex/** are generated runtime files.
No scheduled job performs this conversion. The agent that changes the Claude source runs the
matching command immediately and reviews the generated result before finishing the task.
After changing a project CLAUDE.md or any project-local .claude/** file, immediately run:
~/.claude/scripts/sync-to-codex.sh --project "$PWD" --apply
If sync reports a conflict, stop and report it. Commit generated project .codex/** / AGENTS.md
changes with their Claude sources, except .codex/.sync/**, which is host-local runtime state.
When an approved deletion or rename produces orphaned managed outputs, verify that every reported
path corresponds to that approved source change, then remove those generated leftovers with:
~/.claude/scripts/sync-to-codex.sh --project "$PWD" --apply --prune --confirm-delete
If the orphan list contains anything else, stop and report it instead of pruning unrelated output.
What ships with it
3 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.

documentation-writing is a skill published in the GitHub repository pavel-molyanov/molyanov-ai-dev (285 stars, last pushed 19d ago), licensed MIT. It adds 127 tokens to every session and 2,243 once invoked, about $0.0006 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.
