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 | $0.00051 | $0.00369 |
| Opus 5 | $0.00026 | $0.00185 |
| Sonnet 5 | $0.00010 | $0.00074 |
| Haiku 4.5 | $0.00005 | $0.00037 |
Grade A, and why
create-update-readme-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 7d 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
If this skill is used,say:SKILL_CR_UPD_README_LOADED
Goal
Create or update the Features section of a README.md so it is accurate, concise, and aligned with the current capabilities of the project.
Inputs
- Existing
README.mdor newREADME.mdif none exists - Relevant source files, docs, release notes, changelog entries, or user-provided notes
- Any repository-specific terminology already used by the project
Steps
- Read the current
README.mdand locate the existingFeaturessection if present. - Inspect the most relevant sources of truth for current functionality:
- public docs
- recent release notes or changelog
- feature folders / modules
- user-provided notes
- Preserve the project’s tone and terminology.
- Prefer feature statements that describe user-visible capability, not internal implementation details.
- Remove stale, duplicated, or vague feature bullets.
- Group related features when that improves clarity.
- Do not invent features that are not supported by the repo or the provided material.
Output rules
- Keep the section concise.
- Prefer parallel bullet phrasing.
- Use the repository’s existing markdown style.
- If confidence is low for a feature, omit it or explicitly flag uncertainty outside the edited README.md.
Do not
- Do not rewrite the whole README.md unless requested.
- Do not add roadmap items as shipped features.
- Do not describe internal refactors as features.
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.
