researcher is a skill for Claude Code, Codex from maher-naija-pro/claude-researcher. It costs 35 tokens per session (1,876 once invoked), scanned A, original, MIT.

A structured workflow for researching technical problems by searching the internet, testing possible solutions, and recording the findings in organized folders.

In plain words
What is it for?
Use it to investigate a problem, compare possible technical solutions, search different kinds of sources, test candidates, and document what worked or failed.
Why use it?
It helps turn scattered web searches into documented, repeatable investigations with sources and tested results.

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 12d 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.

Researcher

Overview

A structured research workflow that searches the web for solutions to a problem, organizes findings into a dedicated directory, tests each candidate solution, and documents results.

When to Use

  • User asks to "research X", "find solutions for X", or "investigate X"
  • Problem requires searching multiple sources on the internet
  • User wants organized, documented findings rather than a quick answer

Core Pattern

After completing each step, pause and ask the user to confirm before proceeding to the next step.

Step 1 — Create Problem Directory

mkdir <problem_name>_problem/

Use snake_case. Keep it short and descriptive.

→ Confirm with user before proceeding.

Step 2 — Search for Solutions in Parallel

Dispatch multiple subagents (model: claude-sonnet-4-6) — one per search angle. Each subagent:

  • Searches the web for candidate solutions
  • Returns: solution name, summary, source URLs, and page location/section
  • Sources to cover:
    • Community: Stack Overflow, Reddit, Hacker News, dev.to
    • Articles: Medium, InfoQ, DZone
    • Code: GitHub, Papers With Code, npm/PyPI/crates.io package pages
    • Academic: arXiv, Google Scholar, ResearchGate, Semantic Scholar, IEEE Xplore, ACM Digital Library, USENIX, Distill.pub
    • Reference: official docs, tutorials, Wikipedia
    • Video: YouTube conference talks (NeurIPS, ICML, OSDI, CCC, etc.)

Present the list of solutions found to the user.

→ Confirm with user before proceeding (user may exclude solutions).

Step 3 — Create a Directory per Solution

For each candidate solution, create:

<problem_name>_problem/
  solution_<solution_name>/
    README.md
    documentation/

Step 4 — Gather Documentation per Solution

For each solution, dispatch one subagent (model: claude-sonnet-4-6) per source category in parallel:

  • Community: Stack Overflow, Reddit, Hacker News, dev.to
  • Articles: Medium, InfoQ, DZone
  • Code: GitHub, Papers With Code, npm/PyPI/crates.io
  • Academic: arXiv, Google Scholar, ResearchGate, Semantic Scholar, IEEE Xplore, ACM Digital Library, USENIX, Distill.pub
  • Reference: official docs, Wikipedia
  • Video: YouTube conference talks (NeurIPS, ICML, OSDI, etc.)

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.

researcher is a skill published in the GitHub repository maher-naija-pro/claude-researcher (13 stars, last pushed 4mo ago), licensed MIT. It adds 35 tokens to every session and 1,876 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.
