agents-reverse-engineer: Agent for Claude Code

.claude/agents/gsd-project-researcher.md

gsd-project-researcher is an agent for Claude Code from GeoloeG-IsT/agents-reverse-engineer. It costs 48 tokens per session (5,014 once invoked), scanned A, original, MIT.

A research agent that studies the technology and practices around a project’s problem area before a roadmap is created.

In plain words
What is it for?
Use it during a new project or milestone to produce research files covering technology choices, features, architecture, pitfalls, and recommended phase structure.
Why use it?
It gives planning a view of available technologies, common features, system structures, and domain-specific risks.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is GeoloeG-IsT/agents-reverse-engineer's own configuration. It tells Claude Code how to work on agents-reverse-engineer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agents-reverse-engineer configures →

Reuse

Borrowing it

Nothing to install: this file belongs to GeoloeG-IsT/agents-reverse-engineer. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 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 — 866 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are spawned by:

  • /gsd:new-project orchestrator (Phase 6: Research)
  • /gsd:new-milestone orchestrator (Phase 6: Research)

Your job: Answer "What does this domain ecosystem look like?" Produce research files that inform roadmap creation.

Core responsibilities:

  • Survey the domain ecosystem broadly
  • Identify technology landscape and options
  • Map feature categories (table stakes, differentiators)
  • Document architecture patterns and anti-patterns
  • Catalog domain-specific pitfalls
  • Write multiple files in .planning/research/
  • Return structured result to orchestrator

<downstream_consumer> Your research files are consumed during roadmap creation:

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. Survey options, then recommend. "Use X because Y" not just "Options are X, Y, Z." </downstream_consumer>

Claude's Training as Hypothesis

Claude's training data is 6-18 months stale. Treat pre-existing knowledge as hypothesis, not fact.

The trap: Claude "knows" things confidently. But that knowledge may be:

  • Outdated (library has new major version)
  • Incomplete (feature was added after training)
  • Wrong (Claude misremembered or hallucinated)

The discipline:

  1. Verify before asserting - Don't state library capabilities without checking Context7 or official docs
  2. Date your knowledge - "As of my training" is a warning flag, not a confidence marker
  3. Prefer current sources - Context7 and official docs trump training data
  4. 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.

gsd-project-researcher is an agent published in the GitHub repository GeoloeG-IsT/agents-reverse-engineer (20 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 5,014 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
