deep-research

deep-research is a skill for Claude Code, Codex from TenureAI/PhD-Zero. It costs 198 tokens per session (3,272 once invoked), scanned A, original, MIT.

A research process for finding, checking, and documenting evidence from multiple sources. It is intended for questions that need more than a quick answer, such as comparing options, investigating causes, or planning an approach.

In plain words
What is it for?
Use it for literature reviews, evidence-based comparisons, root-cause investigations, feasibility studies, design decisions, and implementation planning.
Why use it?
It helps replace unsupported conclusions with checked information and a clear record of where each finding came from.

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 4d 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.

Deep Research

Mission

Produce a deeply researched, evidence-grounded answer with clear provenance and actionable conclusions, and act as the default gateway for external search in research runs.

Search Routing Gate (Mandatory)

All external search during non-trivial research runs must enter through deep-research.

Rules:

  1. do not bypass deep-research with ad hoc direct search when fresh outside evidence is needed
  2. deep-research may choose a lighter or deeper execution depth internally, but it may not silently skip actual search
  3. every deep-research run must perform real WebSearch calls and keep an auditable query trail
  4. if search is skipped because existing evidence is already fresh enough, emit dr_skip_reason with explicit date windows and source counts

Research Type Selection

Choose a primary research_type early:

  1. idea-exploration
  2. debug-investigation
  3. design-decision
  4. implementation-strategy
  5. conflict-resolution

If templates do not fit exactly, adapt structure freely but keep depth, verification, and citations.

Before selecting depth or running any WebSearch queries:

  1. confirm intake_checkpoint_complete=YES
  2. intake must at least define: objective/scope, constraints, and expected deliverable format
  3. route missing-information requests through human-checkpoint
  4. in moderate or detailed, prefer built-in user-question tool (request_user_input)
  5. if built-in tool is unavailable, degrade to concise plain-text questions
  6. if intake is incomplete, remain in clarification phase and do not run search, decomposition, or synthesis

Frontier-First Scout (Mandatory)

Every deep-research run must begin with a frontier-first scout before final depth selection.

Scout requirements:

  1. run at least 6-10 queries total
  2. cover at least:
    • bleeding-edge topic queries
    • frontier topic queries
    • one verification query family
    • one counter-evidence or criticism query family
  3. capture representative freshness, source quality, and contradiction density
  4. use scout evidence to choose final depth

Changes

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 TenureAI/PhD-Zero (52 stars, last pushed 5mo ago), licensed MIT. It adds 198 tokens to every session and 3,272 once invoked, about $0.0010 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.
