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 | $0.00044 | $0.00790 |
| Opus 5 | $0.00022 | $0.00395 |
| Sonnet 5 | $0.00009 | $0.00158 |
| Haiku 4.5 | $0.00004 | $0.00079 |
Grade A, and why
severity-mapping 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 3d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Severity Mapping
Canonical severity definitions shared across web, document, and markdown audit domains.
Canonical Severity Levels
| Level | Definition | WCAG Conformance | Score Impact |
|---|---|---|---|
| Critical | Blocks access entirely for one or more user groups. No workaround exists. | Fails Level A | -15 to -22 points |
| Serious | Severely impairs access; a workaround may exist but is unreasonable. | Fails Level A or AA | -5 to -10 points |
| Moderate | Causes friction or confusion; most users can still complete the task. | Fails Level AA (advisory) | -2 to -4 points |
| Minor | Polish issue; no meaningful barrier for most users. | Technique deviation | -1 point |
Cross-Domain Equivalents
| Canonical Level | Web (axe-core / Playwright) | Document (Office/PDF) | Markdown |
|---|---|---|---|
| Critical | critical (axe-core) |
Missing document title; untagged PDF; missing heading structure | Broken anchor link leading to dead navigation |
| Serious | serious (axe-core) |
Missing alt text on informational image; table has no headers | Ambiguous link text (e.g., "click here"); missing alt text on image |
| Moderate | moderate (axe-core) |
Merged table cells; color-only data encoding | Skipped heading level; missing table caption |
| Minor | minor (axe-core) |
Decorative image with non-empty alt; redundant bookmark | Emoji in heading; em-dash used as list separator |
Score Impact Rules
Score impacts listed above are additive per finding. When the same issue recurs across many elements:
- First occurrence — full deduction
- Same issue type, same page/file — no additional deduction (already counted once per issue rule)
- Same issue type, different page/file — full deduction applies again to the new page/file score
Conversion Rules (Normalizing Cross-Domain Reports)
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.

severity-mapping is a skill published in the GitHub repository Community-Access/accessibility-agents (405 stars, last pushed 26d ago), licensed MIT. It adds 44 tokens to every session and 790 once invoked, about $0.0002 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 2026-09-03.
