deep-research

deep-research is a skill for Claude Code, Codex from vanillagreencom/kendex. It costs 21 tokens per session (1,059 once invoked), scanned A, original, MIT.

A research procedure for investigating technical systems, vendors, libraries, or technologies and recording sourced findings.

In plain words
What is it for?
It creates a findings report with research metadata and a separate raw-data file, using Exa when available and validating the completed report.
Why use it?
It keeps research evidence, citations, provider data, and validation steps organized instead of mixing unsupported claims into the final report.

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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/deep-research.test.mjs), 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deep Research

Problem with this skill? Run kendex report — it files to the owning repo automatically. Do not hand-file.

In Pi with the web_research tool active, use that tool, passing outputPath when creating a report. In every other harness, run scripts/deep-research with EXA_API_KEY set.

Rules

  • Exa is the research source. Substitute a general web search only when Exa is unavailable and the user approves the fallback.
  • Write findings.md to the path the caller requested, exactly.
  • Cite sources for material claims. Provider payloads go in the sidecar JSON (findings.raw.json beside the report by default), never inline. Sanitize evidence excerpts: source-page headings must not render as headings.
  • Once the report and its sidecar exist, run validate and stop. No local reproduction, benchmarks, tests, code inspection, or implementation unless the caller asked for it.
  • A missing EXA_API_KEY fails with setup instructions. The value may be a key or a 1Password op://vault/item/field reference when the op CLI is installed and signed in.
  • Every mode uses the same findings sections. Record mode and source counts in ## Research Metadata.

What ships with it

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 vanillagreencom/kendex (65 stars, last pushed yesterday), licensed MIT. It adds 21 tokens to every session and 1,059 once invoked, about $0.0001 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.
