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 | $0.00489 | $0.00489 |
| Opus 5.5 | $0.00196 | $0.00196 |
| Sonnet 5.5 | $0.00098 | $0.00098 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
a11y-toolkit 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 4d 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
AGENTS.md — working on a11y-toolkit
Rules for coding agents (and humans) contributing to this repository.
What this codebase is
A zero-dependency (stdlib-only) WCAG 2.2 accessibility engine + MCP server
(32 tools) + CLI. Python 3.9+. The engine runs as an MCP server, a CLI
(a11ytoolkit), and is vendored by a11y.es (production). Zero telemetry is a
product promise — never add phone-home code.
Non-negotiable invariants (all pinned by tests — make test runs them)
python3 tests/test_solido.py— es/en message catalogs key-identical, every finding has_remremediation, version files aligned, tool/prompt counts consistent across every surface, hostile-HTML fuzz never crashes.python3 tests/test_naming.py— the public surface and the code are English-only: tool params, enums, dict keys, identifiers, string-key READS, phrase-table/JS placeholder consistency. Spanish lives ONLY inlang=esoutput content and comments.python3 tests/test_contract.py— tool schema ↔ dispatcher ↔ function signature must agree mechanically.- Signal→criterion map and Understanding-URL coverage are pinned in test_solido.
Conventions
- Release flow:
make release V=X.Y.Z(atomic bump, fast-suite gate, single v-prefixed commit, tag, push — PyPI publishes the tag). No intermediate work commits; the working tree is picked up whole. - Internal/strategy material NEVER goes in this repo (pre-commit guard blocks it; drafts live outside). Public docs are English; CHANGELOG keeps history.
- Bilingual output: every user-facing message exists in es AND en catalogs.
- Finding emission:
add(severity, 'X.Y.Z', 'signal_name')— a new signal automatically joins the signal→criterion map (test re-derives it); a new message key needs its_remtwin in both languages.
After changing anything
make test # all suites; red means the invariant you touched is load-bearing
The accessibility rule applies to this repo too: it must audit clean.
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.

a11y-toolkit AGENTS.md is an instructions file published in the GitHub repository kinti/a11y-toolkit (2 stars, last pushed 2d ago), licensed MIT. It adds 489 tokens to every session, about $0.0020 per session on Opus 5.5. 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 2026-10-24.
