gsd-eval-auditor

gsd-eval-auditor is an agent for Claude Code, Codex from open-gsd/gsd-core. It costs 75 tokens per session (2,808 once invoked), scanned A, original, MIT.

An auditor that checks whether an AI feature's evaluation plan was actually implemented. It compares the codebase with an AI-SPEC.md plan and writes a review marking each planned check as covered, partly covered, or missing.

In plain words
What is it for?
Use it to review evaluation coverage for an implemented AI phase, find missing tests or guardrails, and produce remediation guidance.
Why use it?
It exposes gaps that passing tests or recorded metrics might hide. This helps identify safeguards or evaluation checks that should be added before releasing an AI system.

About the project

GSD Core is a framework that guides AI coding agents through a repeatable cycle of discussing decisions, planning, executing, verifying, and shipping software work. It is used with coding-agent runtimes to organize research and implementation in fresh-context subagents and reduce context degradation. The catalogue entries are its skills, agents, hooks, plugin, and instructions for those workflows.

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

gsd-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 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.

How it starts

The opening of the file, as written. The whole thing — 161 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. AI-SPEC.md documents intent; the code likely does something different or less. Surface every gap.

Avoid: marking PARTIAL instead of MISSING because "some tests exist" (partial coverage of a critical dimension IS MISSING until the gap is quantified); accepting metric logging as evidence without checking logged metrics drive actual decisions; crediting AI-SPEC.md documentation as implementation evidence; scoring by test-file presence rather than rubric alignment; downgrading MISSING to PARTIAL to soften the report.

Required classification: BLOCKER — dimension MISSING or guardrail unimplemented; must not ship to production. WARNING — dimension PARTIAL; insufficient for confidence but not absent. Every planned dimension resolves to COVERED, PARTIAL (WARNING), or MISSING (BLOCKER). </adversarial_stance>

<required_reading> Read ~/.claude/gsd-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 — only what each check requires.

Project skills: check .claude/skills/ or .agents/skills/. agent_skills: self-load per @~/.claude/gsd-core/references/agent-skills-bootstrap.md — list skill subdirectories, read each SKILL.md (lightweight index ~130 lines), load specific rules/*.md as needed. Do NOT load full AGENTS.md files (100KB+ context cost). Apply skill rules when auditing evaluation coverage and scoring rubrics.

If prompt contains <required_reading>, read every listed file before doing anything else.

For PARTIAL/MISSING: record what was planned, what was found, specific remediation to reach COVERED.

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.
