ADR Review

Multi-agent debate pattern for rigorous ADR validation. Orchestrates 6 specialized agents through structured review rounds until consensus or 10 rounds maximum.

Quick Start

# Manual triggers:
/adr-review .agents/architecture/ADR-005-api-versioning.md
"review this ADR"
"validate ADR-005"

Automatic Detection: A Claude Code hook (Invoke-ADRChangeDetection.ps1) runs at session start and detects ADR changes, prompting you to invoke this skill. The pre-commit hook also detects staged ADR files and displays a reminder.

Input	Output	Consensus Required
ADR file path	Debate log + Updated ADR	6/6 Accept or D&C

File Triggers

Pattern	Location	Events
ADR-*.md	.agents/architecture/	create, update, delete
ADR-*.md	docs/architecture/	create, update, delete

Detection: .claude/skills/adr-review/scripts/Detect-ADRChanges.ps1

When to Use

MANDATORY Triggers (automatic):

• Architect creates or updates an ADR
• ANY agent modifies .agents/architecture/ADR-*.md

User-Initiated Triggers (manual):

• User requests ADR review ("review this ADR", "validate this decision")
• User requests multi-perspective validation for strategic decisions

Agent Roles

Agent	Focus	Tie-Breaker Role
architect	Structure, governance, coherence, ADR compliance	Structural questions
critic	Gaps, risks, alignment, completeness	None
independent-thinker	Challenge assumptions, surface contrarian views	None
security	Threat models, security trade-offs	None
analyst	Root cause, evidence, feasibility	None
high-level-advisor	Priority, resolve conflicts, break ties	Decision paralysis

Debate Protocol

Phase	Purpose	Details
Phase 0	Related work research	Search issues/PRs for context
Phase 1	Independent review	Each agent reviews ADR
Phase 2	Consolidation	Identify consensus and conflicts
Phase 3	Resolution	Propose updates for P0/P1 issues
Phase 4	Convergence check	Agents vote: Accept/D&C/Block

Consensus: All 6 agents Accept OR Disagree-and-Commit. Max 10 rounds.

See references/debate-protocol.md for full phase details.

Deletion Workflow

Phase	Purpose
D1	Detection - identify deleted ADR
D2	Impact assessment - find dependencies
D3	Archival decision - archive accepted ADRs
D4	Cleanup - update references

See references/deletion-workflow.md for full workflow.

Issue Resolution

Priority	Requirement	Gate
P0	Must resolve	BLOCKING
P1	Resolve OR defer with issue	BLOCKING
P2	Document	Non-blocking

See references/issue-resolution.md for deferral protocol.

Scripts

Script	Purpose
Detect-ADRChanges.ps1	Detect ADR file changes for auto-trigger

# Basic detection
& .claude/skills/adr-review/scripts/Detect-ADRChanges.ps1

# Compare to specific commit
& .claude/skills/adr-review/scripts/Detect-ADRChanges.ps1 -SinceCommit "abc123"

Verification Checklist

After skill invocation:

• Debate log exists at .agents/critique/ADR-NNN-debate-log.md
• ADR status updated (proposed/accepted/needs-revision)
• All P0 issues addressed or documented
• Dissent captured for Disagree-and-Commit positions
• Recommendations provided to orchestrator

Anti-Patterns

Avoid	Why	Instead
Single-agent ADR review	Misses domain expertise	Use full 6-agent debate
Skipping Phase 0	Duplicates existing work	Always research first
Ignoring D&C dissent	Loses important context	Document all reservations
Manual ADR monitoring	Error-prone	Use Detect-ADRChanges.ps1
Deleting accepted ADRs without archive	Loses knowledge	Always archive accepted ADRs
