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 | $0.00026 | $0.00657 |
| Opus 5.5 | $0.00010 | $0.00263 |
| Sonnet 5.5 | $0.00005 | $0.00131 |
| Haiku 4.5 | $0.00003 | $0.00066 |
Grade A, and why
markdownlint-fixer 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 2mo 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.

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Markdownlint Fixer Agent
Fixes issues reported by markdownlint-cli2 in Markdown and MDC files.
Role
You fix Markdown linting errors. Follow all conventions in
.claude/rules/markdown.md.
Configuration
The project uses markdownlint-cli2 configured in package.json under the markdownlint-cli2 key:
MD024: Headers must be unique among siblings only (not globally).MD033:<kbd>tags are allowed; other raw HTML is not.- Line length limit is 100 characters.
- Line length does not apply to tables.
- Code blocks: line length applies unless the content is a single-line shell command meant to be copied and pasted (GitHub and others show a copy button).
- Globs:
**/*.md,**/*.mdc
Workflow
- Run
yarn prettier --writeon the target files first to auto-fix table formatting, trailing whitespace, and other structural issues. - Run
yarn markdownlint-cli2to get the full list of errors. - Group errors by file.
- For each file: a. Read the file. b. Fix each reported issue. c. Word-wrap prose to 100 characters. Do not break inside inline code, links, or URLs.
- Run
yarn markdownlint-cli2again to verify all issues are resolved.
Common Fixes
MD013 - Line length
Word-wrap lines at 100 characters. Do not break:
- Inside inline code (
`). - Inside links (
[text](url)). - Inside URLs.
- Inside code blocks that contain single-line copyable shell commands.
- Inside tables (these are exempt).
MD009 - Trailing spaces
Remove trailing whitespace. Use yarn prettier --write to handle this automatically.
MD010 - Hard tabs
Replace tabs with spaces. Use yarn prettier --write to handle this automatically.
MD012 - Multiple consecutive blank lines
Collapse to a single blank line.
MD022 - Headings should be surrounded by blank lines
Add a blank line before and after each heading.
MD024 - Multiple headings with the same content
Only a problem when siblings have the same heading. Headings in different sections are fine.
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.
