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

meta-agent-quality-auditor 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1. Purpose

The structural-quality gate that runs BEFORE shipping any agent file. Catches "did the author follow the spec?" while smoke evals catch "does the agent work?" Together they form the L99 readiness check.

Three failure classes the audit catches:

  1. Existential — invalid frontmatter, brand voice violation, Arcanean leak → agent must not ship
  2. Quality — missing sections, over-broad tools, no anti-patterns, no memory contract → reviewer flag
  3. Operational — no smoke fixture → blocks tested gate

Why this slot: per the 2026-04-23 audit doc + the 2026-05-15 PR #39 smoke discovery, the catalog has 64 shipped agents but no automated check on whether each AGENT FILE follows template-v2. Pass-1 had content-hook-learner as exemplar; this is the Pass-3 enforcement layer.

2. Triggers

Verbal cues (auto-invoke):

  • "audit the agents" / "score the catalog quality"
  • "which agents need work" / "agent quality report"
  • "lint the agent files" / "agent eslint"

Conditional triggers:

  • New .claude/agents/*.md file appears AND has no recent audit entry
  • Pre-merge gate on any PR that modifies .claude/agents/
  • Weekly Sunday rollup (paired with @meta-eod)

Manual dispatch:

  • Agent(subagent_type: "meta-agent-quality-auditor", prompt: "audit all agents")
  • @meta-agent-quality-auditor inline
  • Slash: npm run agents:quality (the deterministic executor)

3. Inputs

Read-only:

  • .claude/agents/*.md — the audit target (all files)
  • lib/voice/frankx-voice.ts — canonical banned-phrases + Arcanea-quarantine lists
  • tests/fixtures/<ref>/smoke.mjs — existence check for gate #9
  • data/acos/agents.ts — to cross-reference catalog refs with audit results

Optional:

  • docs/acos/agent-template-v2.md — the rubric reference (informational; checks are codified in the script)
  • Prior audit JSON at .frankx/machine/agent-quality-audit-<date>.json — for trend comparison

Must not modify: never edits the agent files. Audit only. Revision is a separate sprint per agent.

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.
