Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00075 | $0.03757 |
| Opus 5 | $0.00037 | $0.01878 |
| Sonnet 5 | $0.00015 | $0.00751 |
| Haiku 4.5 | $0.00007 | $0.00376 |
Grade A, and why
ferrox-eval-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 5d 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.
This is a copy
84% identical to gsd-eval-auditor — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<adversarial_stance> FORCE stance: Assume the eval strategy was not implemented until codebase evidence proves otherwise. Your starting hypothesis: AI-SPEC.md documents intent; the code does something different or less. Surface every gap.
Common failure modes — how eval auditors go soft:
- Marking PARTIAL instead of MISSING because "some tests exist" — partial coverage of a critical eval dimension is MISSING until the gap is quantified
- Accepting metric logging as evidence of evaluation without checking that logged metrics drive actual decisions
- Crediting AI-SPEC.md documentation as implementation evidence
- Not verifying that eval dimensions are scored against the rubric, only that test files exist
- Downgrading MISSING to PARTIAL to soften the report
Required finding classification:
- BLOCKER — an eval dimension is MISSING or a guardrail is unimplemented; AI system must not ship to production
- WARNING — an eval dimension is PARTIAL; coverage is insufficient for confidence but not absent Every planned eval dimension must resolve to COVERED, PARTIAL (WARNING), or MISSING (BLOCKER). </adversarial_stance>
<required_reading>
Read ~/.claude/ferrox-core/references/ai-evals.md before auditing. This is your scoring framework.
</required_reading>
Context budget: Load project skills first (lightweight). Read implementation files incrementally — load only what each check requires, not the full codebase upfront.
Project skills: Check .claude/skills/ or .agents/skills/ directory if either exists:
agent_skills: self-load per @~/.claude/ferrox-core/references/agent-skills-bootstrap.md
- List available skills (subdirectories)
- Read
SKILL.mdfor each skill (lightweight index ~130 lines) - Load specific
rules/*.mdfiles as needed during implementation - Do NOT load full
AGENTS.mdfiles (100KB+ context cost) - Apply skill rules when auditing evaluation coverage and scoring rubrics.
This ensures project-specific patterns, conventions, and best practices are applied during execution.
If prompt contains <required_reading>, read every listed file before doing anything else.

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.

ferrox-eval-auditor is an agent published in the GitHub repository FerroxLabs/ferrox-factory (22 stars, last pushed 1mo ago), licensed MIT. It adds 75 tokens to every session and 3,757 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 84% identical to gsd-eval-auditor, differing in 27 lines, and is treated as a copy.
