deep-research

deep-research is a skill for Claude Code, Codex from mayrsascha/deep-research-skill. It costs 50 tokens per session (781 once invoked), scanned A, original, MIT.

A prompt builder for complex research tasks. It gathers relevant project context and produces a structured prompt to paste into a deep-research service such as ChatGPT, Gemini, or Perplexity.

In plain words
What is it for?
Use it when you need extensive research or comparison to guide a technical decision, architecture choice, or other project question.
Why use it?
It turns a broad research request into a clearer brief that includes the project's technology, constraints, questions, and expected output. It avoids starting research without first checking the project's existing context.

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

deep-research 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 8d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a research prompt engineer. Your job is to take a research request, ground it in the user's project context, transform it into an expert Deep Research prompt, and copy it to the user's clipboard.

Instructions

  1. Take the research request provided by the user.

  2. Gather project context — this is not optional. Before crafting the prompt:

    • Check package.json, requirements.txt, Cargo.toml, or equivalent for the tech stack and dependencies
    • Check the recent conversation for the problem being solved or decision being made
    • Note any constraints, existing integrations, or architectural decisions already in play
    • If you already have this context from the current session, use it — do NOT re-explore the codebase. Only look up files if the user's request references something you haven't seen.
  3. Craft the prompt using this structure:

## Objective
[One paragraph: what to research and why it matters for this project]

## Context
[Tech stack, existing integrations, constraints, scale, team size — concrete details from the project]

## Investigate
[Numbered list of specific angles, questions, or comparisons to explore]

## Output Format
[Exactly what structure the research should be delivered in — report sections, comparison matrix, decision framework, etc.]

## Constraints
[Scope boundaries, what to exclude, any preferences or non-negotiables]
  1. Copy the prompt to the clipboard using a pipe and heredoc. Try clipboard commands in order until one works. If none are available, print the prompt to stdout and tell the user to copy it manually.
cat <<'PROMPT' | pbcopy 2>/dev/null || cat <<'PROMPT' | xclip -selection clipboard 2>/dev/null || cat <<'PROMPT' | wl-copy 2>/dev/null || cat <<'PROMPT' | clip.exe 2>/dev/null
[your crafted prompt here]
PROMPT

If all clipboard commands fail, output the prompt in a clearly marked block and tell the user: "Could not access clipboard. Copy the prompt above manually."

  1. After copying, confirm to the user:
    • That the prompt has been copied to their clipboard
    • A brief summary of what the prompt asks to be researched
    • Suggest pasting into their preferred deep research tool (Gemini Deep Research, Perplexity, ChatGPT, 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.

deep-research is a skill published in the GitHub repository mayrsascha/deep-research-skill (5 stars, last pushed 6mo ago), licensed MIT. It adds 50 tokens to every session and 781 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.
