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 | $0.00406 | $0.00406 |
| Opus 5 | $0.00203 | $0.00203 |
| Sonnet 5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
writing-skills AGENTS.md 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 5d 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.
What it actually says
Repository Instructions
Assistant configuration is canonical under .claude/. Codex discovers this
repository's skills from .agents/skills/ (generated). Regenerate every
surface with scripts/sync-mirrors.sh; verify with --check.
Skills and commands
Codex discovers both from .agents/skills/.
Reusable skills (19): accent-dial, audit-references, bake-off, cold-review, critic-apply, critic-panel, filter-tells, humanize, inject-vernacular, match-outline, match-structure, match-voice, patent-disclosure, pattern-language, reverse-outline, tighten-style, tune-anchors, update-references, voice-critic.
Python-backed skills run in a pixi environment that ships beside them:
run .agents/scripts/ensure-env.sh once per machine, then invoke scripts
with pixi run --manifest-path .agents/pixi.toml python <script>.
API credentials resolve through the repository's gitignored .secrets/
directory, never from the skills tree — see the secrets rule below.
Conventions
These are summaries; the canonical rule files hold the detail.
- The
.secrets/Directory Contract — API credentials belong to the repository you are working in, never to the skills. See.claude/rules/secrets.md. - Technical Document Types — We catalog the document types of standards bodies and engineering practice. See
.claude/rules/technical-document-types.md. - The
writing-voice/Directory Contract — Any writing repository may carry awriting-voice/directory of exemplar samples that define the target voice for text generated in that repository. See.claude/rules/writing-voice.md.
Before committing, run the repository's consistency check if it defines one, and commit after each round of edits rather than accumulating them.
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.

writing-skills AGENTS.md is an instructions file published in the GitHub repository petar-djukic/writing-skills (4 stars, last pushed 6d ago), licensed MIT. It adds 406 tokens to every session, about $0.0020 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 2026-08-31.
