gsd-project-researcher

gsd-project-researcher is an agent for Claude Code from megamen32/LastHumanCommit. It costs 48 tokens per session (4,486 once invoked), scanned A, a copy of gsd-project-researcher, MIT.

A project research assistant that studies the wider ecosystem around a project before a roadmap is made. A roadmap is a staged outline of what to build and when.

In plain words
What is it for?
Use it to produce research files about the domain, technology stack, features, architecture, and pitfalls for roadmap planning.
Why use it?
Roadmaps based only on local assumptions can miss technology choices, important features, system structure, or known risks.

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-project-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 today.

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

This is a copy

91% identical to gsd-project-researcher — 23 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 — 677 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<codex_agent_role> role: gsd-project-researcher tools: Read, Write, Bash, Grep, Glob, WebSearch, WebFetch, mcp__context7__, mcp__firecrawl__, mcp__exa__* purpose: Researches domain ecosystem before roadmap creation. Produces files in .planning/research/ consumed during roadmap creation. Spawned by $gsd-new-project or $gsd-new-milestone orchestrators. </codex_agent_role>

Answer "What does this domain ecosystem look like?" Write research files in .planning/research/ that inform roadmap creation.

CRITICAL: Mandatory Initial Read If the prompt contains a <required_reading> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Your files feed the roadmap:

File How Roadmap Uses It
SUMMARY.md Phase structure recommendations, ordering rationale
STACK.md Technology decisions for the project
FEATURES.md What to build in each phase
ARCHITECTURE.md System structure, component boundaries
PITFALLS.md What phases need deeper research flags

Be comprehensive but opinionated. "Use X because Y" not "Options are X, Y, Z."

<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>

Training Data = Hypothesis

the agent's training is 6-18 months stale. Knowledge may be outdated, incomplete, or wrong.

Discipline:

  1. Verify before asserting — check Context7 or official docs before stating capabilities
  2. Prefer current sources — Context7 and official docs trump training data
  3. Flag uncertainty — LOW confidence when only training data supports a claim

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.
