deep-research

deep-research is a skill for Codex from B143KC47/deep-research-skill. It costs 83 tokens per session (1,851 once invoked), scanned A, original, MIT.

A research workflow for checking claims across several sources, including papers, projects, and other evidence. It keeps the questions, sources, claims, and limitations traceable.

In plain words
What is it for?
It is for literature reviews, paper and project reviews, due diligence, fact-checking, current-information checks, and reports with citations.
Why use it?
It reduces the chance of relying on an unchecked statement or missing relevant evidence.

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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/research_ledger.py, tests/test_research_ledger.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Deep Research

Run adaptive, evidence-backed research across broad source classes while keeping claims auditable. The goal is not a fixed number of hops: search widely enough, verify strongly enough, and stop when the answer is well supported or the remaining uncertainty is explicit. Keep private reasoning concise; record public, auditable artifacts: queries, sources, claims, limitations, and evidence IDs.

When to activate, and at what effort

Do not activate for a simple fact, rewrite, translation, summary of provided text, or casual chat — or when the user says to answer only from provided material. If borderline, prefer a quick normal answer unless the user asks for citations, verification, current information, source comparison, or decision-grade evidence.

Otherwise pick effort by risk and ambiguity:

Effort Budget Use for
quick 2-4 hops, 2+ source classes narrow, low-risk verification or citations
standard 5-8 hops, 3+ classes researched synthesis, current-info checks, tool comparison, claim verification
deep 9-14 hops, 4+ classes literature review, paper review, GitHub due diligence, implementation recommendation, local files + web verification
exhaustive 15+ hops or user budget, 5+ classes high-stakes, contested, fast-changing, or legal/medical/financial/security-sensitive topics; explicit requests for comprehensive coverage

If the user did not specify scope, infer a reasonable one, state the assumption briefly, and proceed. Ask for clarification only when the missing detail would change the research target or make the answer unsafe.

Runtime setup

Use the bundled ledger script for nontrivial research so the run has auditable artifacts. In ChatGPT-style sandboxes the skill directory is normally SKILL_DIR=/home/oai/skills/deep-research; otherwise locate the installed deep-research directory. Store run artifacts in a writable task workspace (prefer /mnt/data/research_runs), never inside the skill directory.

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 B143KC47/deep-research-skill (2 stars, last pushed 2mo ago), licensed MIT. It adds 83 tokens to every session and 1,851 once invoked, about $0.0004 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.
