Agent Skills: research-precedent

Hunt for prior work and precedent — has this been done before, and does it apply to us? Searches three precedent sources in parallel: internal codebase (similar implementations to model after), the thoughts archive (prior tickets, decisions, plans, PRs), and external projects (open-source and documented industry patterns via web). Each precedent found is assessed for applicability — what matches our situation, what differs, and a factual transfer-fit class (directly-reusable / adaptable / informative / cautionary-anti-pattern) — then persisted as a precedent register. 'No precedent found' is a valid finding: it tells the caller the work is greenfield. When an external project warrants deep code study, recommends escalation to Scout External Codebase rather than cloning here. Mode-aware: interactive reviews the register; autonomous returns the register path. The right capability for 'has anyone built X before?', 'is there prior art for this pattern?', 'have we solved something like this?'.

<inputs>
  Interactive (user invokes [PR]):
  - What we are seeking precedent FOR (the problem or pattern);
    mentioned sources read first.

  Autonomous (dispatched from a workflow):
  - precedent_for (required): the problem, pattern, or capability we
    are seeking prior art on
  - scope (optional): where to look (internal globs, domains)
  - web_search_approved (boolean): required true to hunt external
    precedent via web-search-researcher
  - output_location (optional): override for the research directory
</inputs>

<outputs>
  A precedent register persisted to the thoughts research directory:
  per-precedent entries with source citation, what-matches,
  what-differs, and a transfer-fit class; plus recommended Scout
  follow-ups for external projects worth deep study. "No precedent
  found" is a valid register. Autonomous mode returns a structured
  signal carrying the register path.
</outputs>

<key-discipline>
  Applicability is factual, not a recommendation. State what matches
  and what differs with evidence, and classify transfer-fit. Do NOT
  say "we should adopt this" — whether to adopt is the orchestrator's
  call. The transfer-fit class is evidence-grading, like a confidence
  level, not an action.

  No precedent is a finding: "hunted internal + thoughts + web; no
  prior art" tells the caller the work is greenfield. Ship it as a
  cited register, not as a failure.

  PR hunts; it does not clone. External precedent is found at
  web-discovery depth. When a project warrants deep code study,
  recommend Scout External Codebase rather than cloning here.

  Hide-the-intent: every child prompt carries the hunt question
  alone — never the parent task's intent.
