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 | $0.00089 | $0.01412 |
| Opus 5 | $0.00044 | $0.00706 |
| Sonnet 5 | $0.00018 | $0.00282 |
| Haiku 4.5 | $0.00009 | $0.00141 |
Grade A, and why
doc-lint 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 10d 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 — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Doc-Lint Skill
Purpose
This skill IS:
- Markdown validator: Checks MD040 (language tags), heading levels, link validity
- Cross-reference checker: Validates links between documents resolve
- JSON structure validator: Checks for duplicate keys, valid structure
- Quality reporter: Produces actionable findings with file:line references
This skill IS NOT:
- Auto-fixer: Reports issues, does not fix them
- Content quality auditor: Checks syntax, not content quality (that's context-audit)
- Full linter: Focused subset of checks relevant to context ecosystems
Validation Categories
1. Markdown Quality
| Check | Severity | Description |
|---|---|---|
| MD040 | LOW | Fenced code blocks without language tag |
| Heading jumps | LOW | h1 to h3 without h2 |
| Broken internal links | MEDIUM | Links to non-existent files |
| Missing frontmatter | MEDIUM | SKILL.md or AGENT.md without frontmatter |
| Trailing whitespace | LOW | Lines ending with spaces |
2. Cross-Reference Validation
| Check | Severity | Description |
|---|---|---|
| Broken file links | HIGH | Markdown links to files that don't exist |
| Broken section anchors | MEDIUM | Links to headings that don't exist in target |
| Orphaned documents | LOW | Files not referenced by any other document |
3. JSON Structure Validation
| Check | Severity | Description |
|---|---|---|
| Duplicate keys | HIGH | Same key appears twice in object |
| Duplicate IDs | HIGH | Same ID in array of objects |
| Trailing commas | MEDIUM | Invalid JSON syntax |
| Malformed structure | HIGH | Parse errors |
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.

doc-lint is a skill published in the GitHub repository walm00/business-context-os (21 stars, last pushed 3mo ago), licensed MIT. It adds 89 tokens to every session and 1,412 once invoked, about $0.0004 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.
