Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

audit-accessibility 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 yesterday.

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

Purpose and inputs

Audit the specified UI against _first/.../QUALITY.md, accessibility docs, and existing a11y tests. The Quality station owns the bar. Stay report-only unless the user asked to fix.

Steps

  1. Load /f-quality and the Quality overlay. Use the named a11y gate. If none exists, report that and run only existing repo tests.
  2. Inspect semantic structure, keyboard access, names, and focus on changed UI.
  3. Run the repository's a11y or component tests. Do not declare WCAG A/AA/AAA unless the overlay names that level.
  4. If fixes are authorized, apply the smallest semantic/ARIA change that meets the overlay.

Verification

  • Findings cite overlay, test, or rendered behavior.
  • No WCAG level was invented.
  • No unsolicited commit.

Handoff

List issues, the gate used, and remaining manual checks.

Changes

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.
