Briefing Orchestrator

/lp-do-briefing produces concise system briefings: current behavior explained end-to-end with evidence, no planning tasks.

Use this skill when:

• You want to understand a system before deciding whether to change it.
• A stakeholder needs a factual snapshot of current behavior.
• You need evidence pointers before writing a spec or planning a change.

Use /lp-do-fact-find instead when you intend to plan or build a change.

Global Invariants

Operating mode

BRIEFING ONLY

Allowed actions

• Read/search files and docs.
• Run non-destructive commands (rg, targeted lint/typecheck) for evidence.
• Inspect targeted git history.

Prohibited actions

• Code changes, refactors, or production data writes.
• Destructive shell/git commands.
• Planning/build execution — this skill ends at a briefing note.

Evidence and quality rules

• Non-trivial claims require file/line pointers.
• Unknowns must include a concrete verification path.
• Omit empty sections or collapse to one-line Not investigated: <reason>.

Required Inputs

• Topic or system area to understand.
• At least one location anchor (path guess, route, endpoint, error/log, or user flow).

If either is missing, ask only the minimum follow-up questions needed to unblock.

Phase 0: Queue Check Gate

Load and follow: ../_shared/queue-check-gate.md (briefing mode).

Phase 1: Topic Selection

Fast path (argument provided)

• Argument is a topic, file path, or system area → proceed to sufficiency gate.

Discovery path (no argument)

• Ask the user what system, feature, or behavior they want to understand.

Phase 2: Sufficiency Gate

Do not start investigation until topic and location anchor are both satisfied.

Phase 3: Investigate

Load and follow:

• modules/briefing.md

Phase 4: Persist Artifact

• Output path: docs/briefs/<topic-slug>-briefing.md
• Fallback: docs/plans/<topic-slug>-briefing.md
• Template: docs/briefs/_templates/briefing-note.md
• Fill with evidence. Omit empty sections.

Completion Message

Briefing complete. Note saved to <path>. This documents current behavior and evidence pointers. No planning artifact was produced. Use /lp-do-fact-find when you are ready to plan a change.
