• Load balancing logic

Model Routing Table

The orchestrator is the authoritative source for model selection. When spawning any agent via the Agent tool, pass the model explicitly using this table. Each agent's own model: frontmatter is a fallback for direct invocation only.

Agent / Task Class	Model	Rationale
naming-review, complexity-review, claude-setup-review, token-efficiency-review, performance-review	haiku	Pattern-matching, deterministic, low context
test-review, structure-review, js-fp-review, concurrency-review, a11y-review, svelte-review, doc-review	sonnet	Semantic analysis, balanced cost/quality
security-review, domain-review, arch-review, architect	opus	Cross-file reasoning, high-stakes decisions
spec-compliance-review	sonnet	Spec-to-code matching, first gate before quality review
orchestrator	sonnet	Routing and coordination
software-engineer	sonnet (default) / opus for architectural changes	Complexity-driven
qa-engineer, tech-writer, all others	sonnet	Standard analysis

Command Delegation

All review commands are executed under orchestrator direction. When a user triggers a review command, the orchestrator applies model routing and inline review logic before delegating execution.

Command	Delegated workflow	When orchestrator triggers it
/code-review	Full suite review with pre-flight gates	End of Phase 3, or user request
/review-agent	Single-agent review	Inline checkpoint during Phase 3
/agent-audit	Compliance check for agents/skills/hooks	After adding or modifying agents or commands
/agent-eval	Accuracy validation against fixtures	When validating review agent quality
/add-agent	Scaffold new review agent	When a new review capability is needed
/add-plugin	Install and register a plugin	When a new plugin is needed
/apply-fixes	Apply correction prompts	After /code-review generates corrections
/review-summary	Persist session summary	At phase transitions
/semgrep-analyze	Static analysis	As pre-flight context for security-review
/harness-audit	Harness effectiveness analysis	Periodically to review harness staleness

Skills

• Context Loading Protocol - invoke at the start of every task to decide which agents and skills to load, and at phase transitions to unload/swap
• Context Summarization - invoke when context utilization signals are present (high turn count, degraded output quality) or at phase transitions
• Feedback & Learning - invoke when user uses amend/learn/remember/forget keywords, or during learning loop at task completion
• Human Oversight Protocol - invoke when approval gates fire, when user issues override/pause/stop, or when escalating decisions
• Performance Metrics - invoke at task completion to log metrics, and during learning loop to review trends
• Agent & Skill Authoring - invoke when adding new team members, defining new capabilities, or restructuring agent responsibilities
• Quality Gate Pipeline - invoke to enforce the three-phase quality gate: self-validation (Phase 1), verification evidence (Phase 2), and review-correction loops (Phase 3)
• Specs - invoke when routing a new feature request; verify the consistency gate passed before loading implementing agents
• Code Review - invoke after each Phase 3 checkpoint and before committing; runs all relevant review agents with orchestrator-assigned models
• Review Agent - invoke for targeted single-agent inline review during Phase 3 checkpoints
• Eval Audit - invoke after adding or modifying any agent or command file
• Agent Eval - invoke to validate review agent accuracy when fixtures are added or changed
• Apply Fixes - invoke after /code-review generates correction prompts; passes corrections to coding agent
• Review Summary - invoke at phase transitions to persist review state before context compaction
• Agent Add - invoke when a new review capability is needed; runs agent-audit and doc updates automatically
• Agent Remove - invoke when retiring any agent; handles file deletion, registry cleanup, and doc updates
• Semgrep Analyze - invoke as pre-flight context for security-review when SAST findings are needed
• Design Doc - invoke during Research phase for non-trivial features; produces a written design document with user approval before planning
• Branch Workflow - invoke after Phase 3 human gate approval to formalize PR creation, merge strategy, and branch cleanup

Three-Phase Workflow

Every non-trivial task follows three explicit phases. Each phase runs in minimal context, and a human review gate separates each phase. The output of each phase is a structured progress file written to memory/ that onboards the next phase.

Phase 1: Research

• Goal: Understand how the system works, identify all relevant files, locate the problem or feature surface area
• Agents: Orchestrator + sub-agents for exploration (context isolation — sub-agents search, read, and return concise findings so the parent context stays clean)
• Output: A research progress file with file paths, line numbers, data flows, and key findings
• Design doc: For non-trivial features (see Design Doc skill for criteria), produce a design document at docs/specs/{feature-name}.md with problem statement, proposed approach, alternatives, key decisions, and scope boundaries. The human approves the design doc as part of the research gate.
• Human gate: Human reviews the research findings and design doc before planning begins. Catching a misunderstanding here prevents hundreds of bad lines of code downstream.
• Context: Compact after this phase — write progress file, start fresh context for Phase 2

Phase 2: Plan

• Goal: Specify every change to be made — files, snippets, test strategy, verification steps
• Agents: Architect (primary), Product Manager (if requirements unclear), Orchestrator
• Input: Research progress file from Phase 1 + approved design doc (if produced in Phase 1)
• Output: An implementation plan with explicit file changes, test expectations, and acceptance criteria
• Automated plan review: Before the human gate, dispatch a plan-reviewer subagent using the prompts/plan-reviewer.md template. The reviewer checks completeness, consistency, risk, and scope. If needs-revision, address issues before presenting to the human.
• Human gate: Human reviews the plan. This is the primary review artifact — 200 lines of plan is far more reviewable than 2,000 lines of code. If the plan is wrong, fix it here, not in code.
• Context: Compact after this phase — write progress file, start fresh context for Phase 3

Phase 3: Implement

• Goal: Execute the plan. Write code, run tests, verify at each step.
• Agents: Software Engineer (primary), QA Engineer (validation), others as needed
• Input: Plan progress file from Phase 2
• Subagent dispatch: Use the prompts/implementer.md template when dispatching implementation subagents. For parallel implementation of independent units, use isolation: "worktree" on the Agent tool to give each subagent its own git worktree — this prevents file conflicts when multiple units are implemented concurrently.
• TDD enforcement: The Software Engineer must follow RED-GREEN-REFACTOR for every unit (see TDD skill). The orchestrator verifies that each unit's output includes failing test output → passing test output evidence.
• Output: Working code that passes all tests, acceptance criteria, and code review
• Three-stage inline review: After each discrete unit of work completes, run spec-compliance first, then quality, then browser verification for UI changes:
  1. Stage 1 — Spec compliance: Run spec-compliance-review using the prompts/spec-reviewer.md template. Does the code match the spec? If fail → fix before proceeding to Stage 2.
  2. Stage 2 — Code quality: Run the standard Inline Review Checkpoint (see below) using the prompts/quality-reviewer.md template. Is the code high quality?
  3. Stage 3 — Browser verification (UI changes only): If the plan step involves UI components, run /browse in automated smoke test mode against the running dev server. Capture screenshots, verify rendering, and check basic interaction. If the dev server is not running, skip with a warning (do not fail). Timeout: 30 seconds. Failures enter the review loop (max 2 iterations). This stage is skipped for non-UI changes.
• Final verify: After all units complete and tests pass, run /code-review --changed on all modified files:
  • fail → Software Engineer addresses critical issues, re-run review
  • warn → include findings in human gate summary
  • pass → proceed to doc review
• Doc review: Before the human gate, invoke the tech-writer to review all documentation affected by the changes:
  • Any behavioral or architectural change → check docs/architecture.md, README.md
  • Any configuration or tooling change → check docs/architecture.md (Governance section)
  • Any agent or skill change → check CLAUDE.md, docs/agent_info.md, docs/skills.md, docs/team-structure.md
  • Tech-writer updates outdated sections and confirms all docs reflect current behavior before proceeding
• Human gate: Human reviews the final output. If the plan was good, implementation review is lightweight.
• Context: If implementation is large, compact mid-phase — update the plan progress file with completed steps and continue in a fresh context

Review Depth by Complexity

Each plan step includes a Complexity classification that controls review depth:

Complexity	Inline review behavior
trivial	Skip inline review entirely. The final /code-review --changed covers all files.
standard	Run spec-compliance + quality agents relevant to the change type (see table below).
complex	Run spec-compliance + full quality suite including opus-tier agents (security-review, domain-review, arch-review).

If a step has no complexity annotation, default to standard.

Inline Review Checkpoint

After each discrete unit of work classified as standard or complex (a function, a module, a feature slice — as defined in the Phase 2 plan):

Step 1 — Select agents by what changed:

Changed	Agents to run
JS/TS functions	complexity-review (haiku), naming-review (haiku), js-fp-review (sonnet)
Test files	test-review (sonnet)
API surface / auth	security-review (opus)
Domain/business logic	domain-review (opus)
UI components	a11y-review (sonnet), structure-review (sonnet)
Agent or command files	eval-compliance-check hook runs automatically; also run /agent-audit
Documentation files (.md)	doc-review (sonnet)
Architecture/dependency changes	arch-review (opus)
All changes	structure-review (sonnet) as a baseline
All changes (before quality review)	spec-compliance-review (sonnet) as first gate

Step 2 — Run selected agents in parallel using Agent tool with model from the Routing Table above.

Step 3 — Aggregate findings and apply Review Loop:

• pass / warn → log findings in phase output, continue
• fail → enter the Review Loop below

Review Loop

When any checkpoint agent returns fail:

1. Package findings as structured correction context:

   Review finding — [agent-name] at [file:line]
   Issue: [message]
   Required fix: [suggestedFix]
   

2. Send to Software Engineer: "Revise to address these findings before continuing."
3. Software Engineer revises only the targeted code — no surrounding changes.
4. Re-run only the agents that returned fail.
5. If still fail after 2 iterations → escalate to human with:
   • The original findings
   • Both revision attempts
   • Recommended resolution path
6. warn after any iteration is acceptable; document in phase output and continue.

Phase Transitions

1. Complete the current phase's work
2. Write a structured progress file to memory/ (see Context Summarization skill)
3. Human reviews and approves before proceeding
4. Start new context window for the next phase
5. Load only the progress file + agents needed for the new phase

Decision Log

Significant decisions are appended to memory/decisions.md so they persist across session resets and are visible to subsequent phases.

Log a decision when:

• Routing to a non-default agent for a non-obvious reason
• Choosing between two valid architectural or implementation approaches
• Overriding a routing table default or established convention
• Resolving a conflict between agent recommendations
• Making a scope call that constrains future phases

Do not log routine decisions (standard routing, normal code patterns, expected behavior).

Entry format:

**ID**: DEC-YYYY-MM-DD-NNN
**Date**: YYYY-MM-DD
**Agent**: <agent-name>
**Task**: <brief task context>
**Decision**: <what was decided>
**Rationale**: <why>
**Alternatives rejected**: <other options and why not chosen>

Append the entry to memory/decisions.md using the Write or Edit tool before moving to the next phase.
