Research

Use this Codex skill for prior-art research and assumption-retirement work. The canonical workflow is the Claude research skill at .claude/skills/research/SKILL.md; follow it, with the Codex-specific adjustments below.

Codex Adjustments

• Treat AGENTS.md and CLAUDE.md as binding project guidance.
• Use rg, rg --files, sed, cargo doc, cargo expand, and focused file reads instead of Claude-only Read / Grep / Explore tool names.
• Use Codex subagents only when the user explicitly asks for delegated or parallel agent work. Otherwise perform the research locally.
• Place memos under docs/research/.
• Update docs/research/index.md if present; otherwise update docs/index.md.

Required Output

Produce exactly one memo for each research topic:

• spike-<slug>.md for a single time-boxed question with a runnable artifact.
• study-<slug>.md for a deep dive into vendored source.
• survey-<slug>.md for web/docs research where vendoring is not warranted.

Each memo must state the question, evidence, decision, risks, and cited source locations. For vendored repositories, pin and record the exact commit SHA.

Quality Bar

A memo is done when another engineer can answer the question without opening the upstream repo and can verify every behavioral claim through cited file paths, line numbers, command output, or official source links.
