Calibrate

Calibrate — Orchestrator

Hard stop. Evidence-based calibration. Realign to North Star.

Pattern: This skill uses the orchestrator-subagent pattern. Each phase runs in a fresh context for optimal performance. See docs/guides/ORCHESTRATOR_SUBAGENT_PATTERN.md.

Subagents

Philosophy

Tests adjudicate, not rhetoric. Pursue verifiable truth, not persuasive agreement.

Key insight (DebateCoder, 2025): "Tests are the medium of disagreement, not rhetoric." Rhetorical debate degrades outcomes—voting alone beats extended debate (research/003-debate-or-vote.md).

Execution Flow

1. Setup (Orchestrator)

1. Create session directory:
   mkdir -p sessions/calibrate-{timestamp}

2. Initialize TodoWrite with phases:
   - [ ] Phase 1: Coverage Analysis
   - [ ] Phase 2: Drift Detection
   - [ ] Phase 3: Test-Based Challenge
   - [ ] Phase 4: Synthesis
   - [ ] Phase 5: User Report

3. Gather inputs:
   - phase_name: The phase being calibrated
   - north_star_path: Path to North Star Card
   - requirements_path: Path to REQ-*/AC-* file
   - beads_status: bd list --json

2. Phase 1: Coverage Analysis

Spawn: agents/coverage.md

Input:

{
  "phase_name": "<phase>",
  "session_dir": "sessions/calibrate-{timestamp}",
  "requirements_path": "PLAN/01_requirements.md",
  "beads_status": "<bd list --json output>"
}

Expected output:

{
  "report_path": "sessions/.../01_coverage_report.md",
  "p0_coverage": "4/5 (80%)",
  "gaps_summary": "1 P0 missing bead, 1 P0 missing tests"
}

3. Phase 2: Drift Detection

Spawn: agents/drift.md

Input:

{
  "phase_name": "<phase>",
  "session_dir": "sessions/calibrate-{timestamp}",
  "north_star_path": "PLAN/00_north_star.md",
  "coverage_report_path": "<from Phase 1>"
}

Expected output:

{
  "report_path": "sessions/.../02_drift_report.md",
  "alignment_summary": "5/7 ALIGNED, 1 DRIFTING, 1 OFF-TRACK",
  "drift_items": ["NS-1: Auth method", "NS-3: Mobile support"]
}

4. Phase 3: Test-Based Challenge

Spawn: agents/challenge.md

Input:

{
  "session_dir": "sessions/calibrate-{timestamp}",
  "coverage_report_path": "<from Phase 1>",
  "drift_report_path": "<from Phase 2>"
}

Expected output:

{
  "report_path": "sessions/.../03_challenge_report.md",
  "verified_claims": ["NS-1 drift", "NS-3 mobile gap"],
  "unresolved": ["API rate limit assumption"]
}

5. Phase 4: Synthesis

Spawn: agents/synthesize.md

Input:

{
  "session_dir": "sessions/calibrate-{timestamp}",
  "coverage_report_path": "<from Phase 1>",
  "drift_report_path": "<from Phase 2>",
  "challenge_report_path": "<from Phase 3>"
}

Expected output:

{
  "report_path": "sessions/.../04_synthesis_report.md",
  "decisions": [{"action": "Implement SSO", "priority": "P0"}],
  "user_questions": ["Load test timing?"],
  "preserved_dissent": ["API rate limit adequacy"]
}

6. Phase 5: User Report

Spawn: agents/report.md

Input:

{
  "session_dir": "sessions/calibrate-{timestamp}",
  "synthesis_report_path": "<from Phase 4>",
  "north_star_path": "PLAN/00_north_star.md"
}

Expected output:

{
  "report_path": "sessions/.../05_user_report.md",
  "summary": {"alignment": "5/7", "blocking": 2},
  "user_questions": ["Load test timing?", "bd-130 scope creep?"]
}

7. Finalize (Orchestrator)

1. Update TodoWrite (all phases complete)
2. Read 05_user_report.md
3. Present to user
4. Log changes to .beads/change-log.md if decisions made

Context Optimization

Why subagents beat monolithic calibration:

Research backing:

• research/056-multi-agent-orchestrator.md: +90.2% over single-agent
• research/004-context-length-hurts.md: Context degradation is real

Evidence Standard (All Subagents)

For any non-trivial claim, include at least one:
