triage

name	triage
description	Adaptive pipeline triage skill. Classify task complexity, blast radius, and domain in ≤8 file reads, then emit schema-valid workspace/triage.json that drives all downstream phase composition and agent selection.
use-when	Load for the triage agent at the start of every /team pipeline run. Always the first skill loaded — required before any other agent is spawned.
do-not-use-when	Do not load for unity-dev, architect, tester, or verifier roles. Triage runs only once per pipeline at the start; never re-loaded mid-pipeline.

Triage Skill

The triage agent runs ONCE per /team invocation, before any other agent. It is the only agent that always runs. Everything downstream is derived from its output.

Goal

Produce workspace/triage.json matching .claude/schemas/triage.schema.json in under 8 file reads.

Inputs

• <intent> from the user (bug | feature | refactor | explore)
• <depth> from the user (quick | normal | deep — default normal)
• <task description> free text
• CRG MCP (code-review-graph) — preferred
• ai-game-developer MCP — optional

Procedure

1. CRG first. No file reads until graph evidence exists.

   • get_architecture_overview if domain unknown
   • trace_execution_flow from task keywords
   • get_impact_radius → seed systems_affected and files_touched_estimate

2. Fingerprint up to 5 touched files for API evidence (see .claude/docs/rules/api-fingerprinting-system.md).

   • Compute DOTS_score / Unity_score / Hybrid_score (see .claude/docs/rules/domain-scoring-engine.md).
   • Classify domain. If Ambiguous → confidence_score ≤ 0.5.

3. Classify complexity using the rubric below.

4. Pick verification strategy:

   • bundle — tiny: deterministic verification bundle, no agent
   • verifier — small/medium: verifier agent runs the bundle
   • tester — large/critical: full tester agent
   • stepgated — refactor only

5. Partition ownership when the pipeline has more than one writer (data-tool plus unity-dev, or stepgated refactor). Use repo-root-relative globs. When in doubt: assign only unity-dev (no parallelism).

6. Emit workspace/triage.json via python .claude/scripts/triage.py. That helper writes a schema-valid file; do not hand-write the JSON.

Complexity Rubric

Complexity	Files	Systems	Blast radius	Pipeline (default)
tiny	1	1	isolated	[unity-dev]
small	1–3	1	local	[unity-dev, verifier]
medium	2–5	1–3	local / multi-system	[architect, unity-dev, verifier]
large	5–15	3–6	multi-system	[architect, unity-dev, tester]
critical	>15 OR save/multiplayer/economy/world-init	any	cross-cutting	[architect, unity-dev, data-tool, tester]

Examples:

• "Rename EnemyHP to EnemyHealth" → tiny
• "Fix off-by-one in damage calc" → tiny
• "Health regen not firing after death respawn" → small (1 bug, 1 system)
• "Add stamina component + regen system" → medium
• "Spawner refactor across zones + dungeons" → large
• "Save system migration v3 → v4" → critical

Intent Overrides

• bug → prepend bug-investigation regardless of complexity
• refactor→ prepend refactor-agent + force architect + stepgated verification
• explore → pipeline is empty; triage is the only output
• feature → no override

Depth Modifier

• quick — downgrade complexity by one tier (small→tiny, medium→small). Refuse if blast_radius ≥ multi-system.
• normal — use complexity as classified.
• deep — upgrade complexity by one tier (small→medium, etc.). Tester always spawned. Codex review required at design and at completion.

Confidence Scoring

confidence_score ∈ [0.0, 1.0]:

• 1.0 — Domain unambiguous, blast radius proven via CRG, prior session in repo-knowledge.md covers the same area.
• 0.8 — Domain clear; blast radius best-effort but evidence-backed.
• 0.6 — Domain clear; blast radius partly guessed.
• 0.4 — Domain ambiguous or CRG unavailable.
• ≤0.3 — recommended_pipeline should include an investigator (system-mapper or bug-investigation) before implementation begins.

Parallel execution requires confidence ≥ 0.8 AND complexity ≥ medium AND ownership partition ≥ 2. The orchestrate.py planner enforces this.

Skill Pack Selection

skill_packs[] holds DOTS extras only — modules layered on top of an agent's lane-correct primary skills. Each agent's primary skills are resolved by orchestrate.py (AGENT_PRIMARY_SKILLS), NOT from skill_packs. The Unity-classic lane (unity-dev) gets unity-classic + unity-foundation as its primaries — it does NOT use unity-dots-best-practices as a stand-in Unity layer.

Add up to 4 skill packs to skill_packs[] based on domain:

• DOTS: ecs-job-patterns, burst-safety, memory-safety
• Unity: (none — the Unity lane's unity-classic primary skill IS the Unity classic layer; do NOT add unity-dots-best-practices)
• Hybrid: ecs-job-patterns + ownership-partitioning

skill_packs attach to DOTS lanes only (unity-dots-dev); they are never merged into unity-dev/tester/verifier/data-tool. ownership-partitioning is added whenever parallel_allowed=true so downstream writers respect their assigned globs.

Helper Command

python .claude/scripts/triage.py \
  --intent <bug|feature|refactor|explore> \
  --task "<one line task>" \
  --depth <quick|normal|deep> \
  --complexity <tiny|small|medium|large|critical> \

  --strategy <bundle|verifier|tester|stepgated> \
  --skill-packs <pack1> <pack2> \
  --own "unity-dev=Assets/Scripts/Combat/**" \
  --own "data-tool=Assets/Editor/**" \
  --rationale "<one paragraph justifying complexity, domain, and parallelism>"

Validate before exiting:

python .claude/scripts/orchestrate.py validate workspace/triage.json triage

If validation fails, fix the inputs and re-run. Do not hand-edit the JSON.

Anti-Patterns

• Reading more than 8 files. Triage is a scout, not the investigator.
• Recommending a 4-agent pipeline for a 1-file change.
• Setting parallel_allowed=true with confidence < 0.8.
• Emitting Ambiguous domain with confidence_score > 0.6.
• Skipping CRG and grepping the repo.
• Hand-writing triage.json instead of using the helper.
