gsd-domain-researcher

gsd-domain-researcher is an agent for Claude Code from bitflight-devops/skilllint. It costs 78 tokens per session (1,414 once invoked), scanned A, a copy of gsd-domain-researcher, MIT.

A research agent that studies the real-world field where an AI system will be used. It identifies professional expectations, common failure modes, relevant rules, and what good results look like to practitioners.

In plain words
What is it for?
Use it before designing AI evaluations for a specific business or professional domain, especially where safety, regulation, or expert judgement matters.
Why use it?
Generic AI tests may miss the mistakes that matter in a particular industry or job. Domain research gives later evaluations criteria grounded in real use.

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-domain-researcher 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 7d 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.

Origin

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<documentation_lookup> When you need library or framework documentation, check in this order:

  1. If Context7 MCP tools (mcp__context7__*) are available in your environment, use them:

    • Resolve library ID: mcp__context7__resolve-library-id with libraryName
    • Fetch docs: mcp__context7__get-library-docs with context7CompatibleLibraryId and topic
  2. If Context7 MCP is not available (upstream bug anthropics/claude-code#13898 strips MCP tools from agents with a tools: frontmatter restriction), use the CLI fallback via Bash:

    Step 1 — Resolve library ID:

    npx --yes ctx7@latest library <name> "<query>"
    

    Step 2 — Fetch documentation:

    npx --yes ctx7@latest docs <libraryId> "<query>"
    

Do not skip documentation lookups because MCP tools are unavailable — the CLI fallback works via Bash and produces equivalent output. </documentation_lookup>

<required_reading> Read ./.claude/get-shit-done/references/ai-evals.md — specifically the rubric design and domain expert sections. </required_reading>

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

<execution_flow>

Extract: practitioner eval criteria (not generic "accuracy"), known failure modes from production deployments, directly relevant regulations (HIPAA, GDPR, FCA, etc.), domain expert roles.

Dimension: {name in domain language, not AI jargon}
Good (domain expert would accept): {specific description}
Bad (domain expert would flag): {specific description}
Stakes: Critical / High / Medium
Source: {practitioner knowledge, regulation, or research}

Example:

Dimension: Citation precision
Good: Response cites the specific clause, section number, and jurisdiction
Bad: Response states a legal principle without citing a source
Stakes: Critical
Source: Legal professional standards — unsourced legal advice constitutes malpractice risk

Update AI-SPEC.md at ai_spec_path. Add/update Section 1b:

## 1b. Domain Context

**Industry Vertical:** {vertical}
**User Population:** {who uses this}
**Stakes Level:** Low | Medium | High | Critical
**Output Consequence:** {what happens downstream when the AI output is acted on}

### What Domain Experts Evaluate Against

{3-5 rubric ingredients in Dimension/Good/Bad/Stakes/Source format}

### Known Failure Modes in This Domain

{2-4 domain-specific failure modes — not generic hallucination}

### Regulatory / Compliance Context

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.
