Debrief: $ARGUMENTS

Walk the original Plan for $ARGUMENTS, mine the completed work items and their PRs, and produce a triage-ready learnings document for human review.

Orchestration: agent team

If you are NOT already operating inside an agent team (no prior successful team-creation or subagent-delegation tool call in this session, not spawned into a team context), the very first thing you do is establish team orchestration.

Use the team tool for the current runtime:

• Claude Code >= 2.1.178: there is no TeamCreate tool; the team forms automatically when you spawn the first teammate with Agent. That first spawn should be the bounded specialist needed to start this flow. On older Claude Code that still exposes TeamCreate, the explicit team-create path is also acceptable.
• Codex: do not call TeamCreate; Codex does not expose that Claude tool. Use tool_search with a query like multi-agent tools to load multi_agent_v1, then use multi_agent_v1.spawn_agent for teammate delegation. Treat the first successful spawn_agent call as establishing team orchestration.
• Other runtimes: use the current runtime's tool-discovery mechanism to discover and call the appropriate multi-agent/team tool.

If no team creation or subagent delegation tool is available, explicitly state that team orchestration is unavailable in this runtime, continue as the lead agent, and preserve the workflow's review, verification, and task-tracking obligations locally.

Until the team is established, the first Codex teammate has been spawned, or the no-team fallback has been declared, do NOT call any of: TaskCreate, Skill, MCP tools (Atlassian / Linear / GitHub / Notion), Read, Write, Edit, Bash, Grep, Glob. The initial Claude Agent spawn described above is the only pre-team exception because it establishes the team. Resolving the work-item set, fetching tickets, walking PRs — all of those are tasks for the team you are about to create, not for the lead session before orchestration exists.

If you ARE already inside an agent team (e.g., a teammate invoked this skill via the Skill tool), do NOT create a second team — many harnesses reject double-creates — and do NOT collapse the nested flow into a single inline worker. A nested team-first flow must still bring in the specialists it requires by adding them to the existing team, not by doing the work itself:

• Claude: teams are flat and only the lead can add named teammates, so do NOT call Agent with a name from a teammate (the harness rejects it: "Teammates cannot spawn other teammates — the team roster is flat"). Send the team lead a message naming the specialist teammate(s) this flow needs, their task assignments, and completion criteria, then coordinate through the shared task list until they finish. An anonymous subagent (Agent with name omitted) is permitted only for bounded one-shot work whose result returns directly to you — it is not a substitute for the required lifecycle specialists.
• Codex: do NOT call TeamCreate. If the lead/root agent is addressable (you were given its id/handle), send it a request to multi_agent_v1.spawn_agent the specialist agent(s), including each agent's prompt, ownership, and expected result. If no lead handle exists but spawn_agent is available to you, spawn only the bounded specialist agent(s) this flow needs, wait_agent for their results, and relay those results upward to the parent/lead.

Treat the first successful lead-spawn request (or, on the Codex fallback, the first specialist spawn) as preserving team orchestration. Never satisfy a team-first lifecycle flow by doing all the work inline.

Input

$ARGUMENTS is one of:

If the PRD has no ## Tickets section AND the input is not an epic, stop and report — the Plan flow's PRD back-link step (lisa-prd-backlink) was likely skipped. Suggest re-running Plan to populate the section, or pass the epic key directly.

Gate

Run before mining begins:

1. All work items terminal. Every linked work item must be in a terminal state (Done / Closed / Cancelled equivalent for the tracker). If any item is still open, stop and list the unfinished items — Debrief is post-shipping by definition.
2. PR coverage. Every Done item that was implementable (Story / Task / Bug; not Spike) must have at least one merged PR linked. Items missing a PR are recorded as anomalies to surface in the report rather than silently excluded — a Done item with no PR is itself a learning ("how did this ship?").
3. Headless safety. In headless / -p / scheduled mode, do not block on missing input — fail fast with a clear error listing what was needed.

Flow

Execute the Debrief flow as defined in the intent-routing rule (loaded via the lisa plugin). The rule contains the canonical step sequence (gate, mining, synthesis, output, hand-off). This skill does NOT restate flow steps — change them in the rule, propagate everywhere.

The flow's mining step runs tracker-mining-specialist and pr-mining-specialist in parallel as separate tasks within the team. Both must complete before learnings-synthesizer runs. Express this with blockedBy so the synthesizer task is automatically gated on the two mining tasks.

Exhaustiveness expectation

Debrief is deliberately exhaustive — the human, not the agent, decides what is worth keeping. Specialists should err toward surfacing more candidates, not fewer. A candidate that the synthesizer rates low confidence is still a row in the triage doc; only outright duplicates are dropped.

Output

A markdown triage document at ./debrief/<initiative-slug>-<YYYY-MM-DD>.md (or wherever the project's debrief output directory is configured) containing:

1. Header — initiative name, source PRD/epic link, work-item count, PR count, generation date, gate results.
2. Anomalies — work items missing PRs, items with abnormal status-transition timing, PRs with no review comments at all (signal-of-absence is a learning), etc.
3. Candidate learnings — one row per candidate, grouped by category (Edge case / Recurring gotcha / Process friction / Tooling gap / Convention drift). Each row has:
   • Summary — one sentence
   • Category
   • Evidence — links to the source ticket comment / PR comment / commit / test file (multiple allowed)
   • Recommended persistence destination — the agent's best guess for where this should land if accepted (e.g., "Edge Case Brainstorm checklist → Navigation & URL state", "PROJECT_RULES.md", "memory: project_*.md", "new tooling-gap ticket")
   • Disposition — empty checkbox-style field the human will fill: [ ] Accept / [ ] Reject / [ ] Defer plus a free-text reason
4. Source map — appendix listing every work item and PR walked, so the human can verify completeness.

Before returning, write the Debrief run's direct usage onto the triage document through lisa-usage-accounting so the markdown artifact carries its own ## Lisa Usage section separate from delivery-time usage. If runtime usage is unavailable, record a debrief entry with source: unavailable and nullable token/cost fields instead of skipping the row.

The skill's terminal output is the path to the triage document and a one-line summary of counts per category. Persistence does not happen here — that is lisa-debrief-apply's job.

Hand-off

After producing the triage document, print:

Triage document written to: <path>
Counts: <n> edge cases, <n> gotchas, <n> friction, <n> tooling gaps, <n> convention drift; <n> anomalies
Next: human triage. When done, run `/lisa:debrief:apply <path>` to persist accepted learnings.

Then stop. Debrief never persists learnings on its own.
