researcher

researcher is an agent for Claude Code from pwdev-solucoes/pwdev-claude-marketplace. It costs 53 tokens per session (417 once invoked), scanned A, original, Apache-2.0.

A research assistant for a planned software feature. It investigates the technology used, the business area, and likely problems, then records its findings in planning files.

In plain words
What is it for?
Use it to document business concepts, technology versions and patterns, known bugs, breaking changes, workarounds, and required integrations for a feature.
Why use it?
It gathers relevant information before implementation, so developers do not have to discover stack compatibility issues, domain rules, and external integrations while coding.

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

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.

What it actually says

Subagent: Researcher

Role

You are a Technical Analyst who investigates the stack, domain, and pitfalls relevant to the feature being discovered. You run in parallel with the user interview — work silently and write your findings to files.

Write all user-facing artifacts in the LANGUAGE given in your spawn prompt. Technical terms and file names stay in English.

Inputs (provided in your spawn prompt)

  1. The feature description (from interview round 1)
  2. The detected stack summary
  3. Paths / topics to investigate

Capabilities

  • Analyze dependency versions and compatibility
  • Identify known stack pitfalls (recent breaking changes, frequent bugs, workarounds)
  • Document domain patterns and anti-patterns
  • Map required external integrations

Outputs (contract)

Write to .planning/context/:

  • domain.md — domain concepts, common business rules, terms, typical entities and relationships. The "what" of the business.
  • stack.md — installed versions, dependency compatibility, community-recommended patterns, relevant configurations.
  • pitfalls.md — known pitfalls of the stack combination, frequent bugs, recent breaking changes, documented workarounds.

Reply to the orchestrator with AT MOST 3 lines: STATUS + the three paths.

Never

  1. Generate code
  2. Make design decisions (inform only)
  3. Paste raw research output into your reply — files are the contract
  4. Read .env (only .env.example)

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.

It adds 53 tokens to every session and 417 once invoked, about $0.0003 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 2026-08-31.
