+description: Patterns for running autonomous agent workflows — from simple pipelines to complex multi-agent DAGs. Reference for setting up build-fix loops, continuous PRs, and de-sloppify passes.
+disable-model-invocation: true
+---
+
+# Autonomous Loop Patterns
+
+Reference guide for autonomous agent workflows, ranked by complexity.
+
+## Pattern 1: Sequential Pipeline
+
+**Complexity**: Low
+**Use when**: Simple one-shot tasks chained together
+
+```bash
+# Run a sequence of claude commands
+claude -p "Implement feature X" --output-format json | \
+claude -p "Write tests for the implementation" --output-format json | \
+claude -p "Review the code for issues"
+```
+
+**Pros**: Simple, predictable, easy to debug
+**Cons**: No error recovery, no parallelism
+
+## Pattern 2: Build-Fix Loop
+
+**Complexity**: Medium
+**Use when**: Making the build green after changes
+
+```bash
+MAX_CYCLES=5
+CYCLE=0
+
+while [ $CYCLE -lt $MAX_CYCLES ]; do
+  CYCLE=$((CYCLE + 1))
+  echo "=== Cycle $CYCLE ==="
+
+  # Run build/tests
+  BUILD_OUTPUT=$(npm run build 2>&1)
+  if [ $? -eq 0 ]; then
+    echo "Build passed on cycle $CYCLE"
+    break
+  fi
+
+  # Fix errors
+  claude -p "Fix these build errors. Make minimal changes only:
+$BUILD_OUTPUT"
+
+  if [ $CYCLE -eq $MAX_CYCLES ]; then
+    echo "STALLED after $MAX_CYCLES cycles — escalating"
+    exit 1
+  fi
+done
+```
+
+**Key rules**:
+- Set a MAX_CYCLES limit (3-5 is reasonable)
+- Detect stalls (same error repeating)
+- Use the `loop-operator` agent for monitoring
+
+## Pattern 3: Test-Driven Fix Loop
+
+**Complexity**: Medium
+**Use when**: Fixing failing tests one at a time
+
+```bash
+# Get failing tests
+FAILURES=$(npm test 2>&1 | grep "FAIL")
+
+for test_file in $FAILURES; do
+  claude -p "Fix this failing test. Read the test to understand intent,
+then fix the implementation (not the test):
+File: $test_file"
+done
+
+# Verify all tests pass
+npm test
+```
+
+**Key rules**:
+- Fix implementation, not tests (unless test is wrong)
+- Run full suite after fixes to catch regressions
+- Stop if fix count exceeds threshold
+
+## Pattern 4: Continuous PR Loop
+
+**Complexity**: High
+**Use when**: Processing a backlog of tasks as PRs
+
+```bash
+# Process tasks from a list
+while IFS= read -r task; do
+  BRANCH="auto/$(echo "$task" | tr ' ' '-' | head -c 40)"
+  git checkout -b "$BRANCH" main
+
+  claude -p "Implement: $task
+Requirements:
+- Create a single focused PR
+- Include tests
+- Follow RULES.md conventions"
+
+  # Run verification
+  claude -p "/verification-loop"
+
+  # Create PR if verification passes
+  if [ $? -eq 0 ]; then
+    git push -u origin "$BRANCH"
+    gh pr create --title "$task" --body "Automated implementation"
+  fi
+
+  git checkout main
+done < tasks.txt
+```
+
+**Key rules**:
+- One task = one branch = one PR
+- Run verification before creating PR
+- Set cost/time limits per task
+- Skip tasks that fail after N attempts
+
+## Pattern 5: De-Sloppify Pass
+
+**Complexity**: Medium
+**Use when**: Cleaning up after a fast implementation pass
+
+The insight: **Two focused agents outperform one constrained agent**. First implement fast, then clean up.
+
+```bash
+# Phase 1: Fast implementation (allow some sloppiness)
+claude -p "Implement feature X quickly. Focus on correctness, not polish."
+
+# Phase 2: Cleanup pass
+claude -p "Review and clean up the recent changes:
+1. Remove console.log/debug statements
+2. Add missing error handling
+3. Fix type safety issues (no 'any')
+4. Ensure consistent naming
+5. Add missing JSDoc for public APIs
+
+Do NOT change behavior or add features. Only clean up."
+```
+
+**Key rules**:
+- Cleanup agent must not change behavior
+- Use git diff to scope the cleanup
+- Run tests after cleanup to verify no regressions
+
+## Pattern 6: Multi-Agent DAG
+
+**Complexity**: Very High
+**Use when**: Large features requiring coordinated parallel work
+
+```
+     ┌─────────┐
+     │ Planner │
+     └────┬────┘
+          │
+    ┌─────┼─────┐
+    ▼     ▼     ▼
+  [API] [UI]  [DB]     ← Parallel agents in worktrees
+    │     │     │
+    └─────┼─────┘
+          ▼
+    ┌───────────┐
+    │ Integrator│      ← Merges and resolves conflicts
+    └─────┬─────┘
+          ▼
+    ┌───────────┐
+    │ Reviewer  │      ← Final quality check
+    └───────────┘
+```
+
+**Implementation**:
+
+1. **Planner** decomposes the spec into independent tasks with dependencies
+2. Independent tasks run in **parallel worktrees** (isolated git branches)
+3. **Integrator** merges worktrees, resolves conflicts
+4. **Reviewer** does final quality check
+
+**Key rules**:
+- Use git worktrees for isolation
+- Each agent gets a focused, self-contained task
+- Integrator handles merge conflicts
+- Full verification after integration
+
+## Choosing a Pattern
+
+| Situation | Pattern |
+|-----------|---------|
+| Single task, no iteration needed | 1 (Sequential) |
+| Build is broken, need to fix | 2 (Build-Fix) |
+| Tests are failing | 3 (Test-Driven Fix) |
+| Backlog of independent tasks | 4 (Continuous PR) |
+| Fast implementation needs polish | 5 (De-Sloppify) |
+| Large feature, multiple concerns | 6 (Multi-Agent DAG) |
+
+## Safety Rules (All Patterns)
+
+1. **Always set limits** — Max cycles, max time, max cost
+2. **Always verify** — Run tests/build after each change
+3. **Always detect stalls** — Same error 3x = stop
+4. **Always preserve work** — Commit before risky operations
+5. **Always escalate** — When stuck, stop and ask for human input

+description: Extract patterns and instincts from the current session — what worked, what didn't, what should be remembered. Produces actionable learnings that improve future sessions.
+disable-model-invocation: true
+---
+
+# Continuous Learning
+
+Extract learnings from the current session to improve future work.
+
+## Context
+
+Recent git history:
+!`git log --oneline -10 2>/dev/null || echo "No git history"`
+
+Project rules:
+!`head -30 RULES.md 2>/dev/null || echo "No RULES.md"`
+
+## Steps
+
+### 1. Review the session
+
+Analyze what happened in this session:
+
+- **Tasks completed**: What was accomplished?
+- **Approaches tried**: What methods were used?
+- **Errors encountered**: What went wrong and how was it fixed?
+- **User corrections**: Where did the user redirect or correct the approach?
+- **Surprises**: What was unexpected about the codebase or requirements?
+
+### 2. Extract instincts
+
+An **instinct** is a pattern that should influence future behavior. Categories:
+
+#### Project-specific instincts
+
+Patterns unique to this codebase:
+- Code conventions not captured in RULES.md
+- Hidden dependencies between modules
+- "Gotchas" that aren't obvious from reading the code
+- User preferences for how work should be done
+
+#### Approach instincts
+
+What worked or didn't work:
+- Tools/agents that were effective for specific tasks
+- Sequences of actions that solved problems efficiently
+- Dead ends that should be avoided next time
+
+#### Communication instincts
+
+How the user prefers to interact:
+- Level of detail they want in explanations
+- Whether they prefer to be asked or just shown solutions
+- How they respond to different types of suggestions
+
+### 3. Classify each instinct
+
+For each instinct, determine:
+
+| Field | Description |
+|-------|-------------|
+| **Pattern** | What was observed (specific, not vague) |
+| **Context** | When this applies (file types, tasks, situations) |
+| **Action** | What to do differently next time |
+| **Confidence** | How certain (low/medium/high) based on how many times observed |
+| **Scope** | Project-only or applicable to all projects |
+
+### 4. Decide where to store
+
+Based on scope and type:
+
+| Learning Type | Store In |
+|---------------|----------|
+| User preference | Memory (type: feedback) |
+| Project convention | `RULES.md` or `RECOMMENDATIONS.md` |
+| Codebase gotcha | Code comment or `RECOMMENDATIONS.md` |
+| Tool/agent effectiveness | Memory (type: feedback) |
+| Communication preference | Memory (type: user or feedback) |
+| Temporary state | Don't store — it's ephemeral |
+
+### 5. Output
+
+```markdown
+# Session Learnings
+
+## Summary
+[1-2 sentences: what was accomplished, overall assessment]
+
+## Instincts Extracted
+
+### 1. [Pattern name]
+- **Observed**: [what happened]
+- **Context**: [when this applies]
+- **Action**: [what to do next time]
+- **Confidence**: [low/medium/high]
+- **Store in**: [memory type / RULES.md / RECOMMENDATIONS.md / skip]
+
+### 2. ...
+
+## Recommendations
+- [Changes to RULES.md if any patterns should become rules]
+- [Changes to RECOMMENDATIONS.md if decisions should be recorded]
+- [New memory entries to create]
+
+## Anti-Learnings
+[Things that seemed like patterns but were actually one-off situations — don't generalize these]
+```
+
+### 6. Anti-patterns
+
+- **Over-generalizing** — Don't turn a one-time fix into a permanent rule
+- **Storing ephemera** — Don't save things like "currently debugging X"
+- **Ignoring negative results** — Failed approaches are as valuable as successful ones
+- **Redundant storage** — Don't save what's already in RULES.md or git history
+- **Low-confidence instincts** — If you've only seen it once, note it but don't enforce it

+- **Constraints**: License, bundle size, browser support, security
+
+### 2. Search for existing solutions
+
+Search in order of preference:
+
+1. **Already in project** — Check if a dependency already solves this:
+   - Read `package.json` / `requirements.txt` / `go.mod`
+   - Search codebase for similar implementations
+2. **Package registries** — Search npm, PyPI, crates.io, pkg.go.dev
+3. **MCP servers** — Check if an MCP server provides this capability
+4. **GitHub** — Search for well-maintained repos with the needed functionality
+5. **Framework built-ins** — Check if the framework already provides this (e.g., Next.js Image, React Server Actions)
+
+For each candidate, evaluate:
+
+| Criterion | Check |
+|-----------|-------|
+| Maintenance | Last commit < 6 months, active issues |
+| Popularity | Downloads/stars relative to category |
+| Bundle size | Check via bundlephobia or equivalent |
+| License | Compatible with project license |
+| Security | No known CVEs, dependency tree reasonable |
+| Types | TypeScript types included or available |
+| API quality | Clean API, good docs, follows conventions |
+
+### 3. Decision matrix
+
+Apply this decision framework:
+
+```
+┌─────────────────────────────────────────────────────┐
+│ Does an existing solution meet ≥80% of requirements? │
+└─────────────────────────┬───────────────────────────┘
+                          │
+              YES ────────┼──────── NO
+              │           │         │
+              ▼           │         ▼
+     Is it well-maintained?       Can you compose
+     Is the API acceptable?       2-3 packages to
+              │                   cover 100%?
+         YES  │  NO                │
+          │   │   │           YES  │  NO
+          ▼   │   ▼            │   │   │
+       ADOPT  │  EXTEND        ▼   │   ▼
+              │  (fork/wrap)  COMPOSE  BUILD
+              │                        (custom)
+```
+
+| Strategy | When | Risk Level |
+|----------|------|------------|
+| **Adopt** | Solution fits ≥80%, well-maintained, good API | Low |
+| **Extend** | Good base but needs customization (wrapper/plugin) | Medium |
+| **Compose** | No single solution, but 2-3 packages combine well | Medium |
+| **Build** | No viable existing solution, or critical security/performance need | High |

+disable-model-invocation: true
+---
+
+# Strategic Compact
+
+Evaluate whether `/compact` should be run now, and if so, prepare for it.
+
+## Context
+
+Current conversation state:
+!`echo "Working directory: $(pwd)" && echo "Git branch: $(git branch --show-current 2>/dev/null)" && echo "Modified files: $(git diff --name-only 2>/dev/null | wc -l | tr -d ' ')" && echo "Staged files: $(git diff --cached --name-only 2>/dev/null | wc -l | tr -d ' ')"`
+
+## When to Compact
+
+Use this decision table:
+
+| Trigger | Should Compact? | Priority |
+|---------|----------------|----------|
+| Phase transition (planning → implementation) | Yes | High |
+| Starting a new major feature | Yes | High |
+| After completing a large task (before next) | Yes | Medium |
+| Context feels sluggish or repetitive | Yes | Medium |
+| Mid-implementation (code partially written) | **No** — finish first | - |
+| Debugging an active issue | **No** — need full context | - |
+| Waiting for user input | Maybe — depends on context size | Low |
+
+### Do NOT compact when:
+
+- You're in the middle of writing code (partial state will be lost)
+- You're debugging and need the full error trail
+- You have uncommitted understanding of complex relationships
+- The user just gave important instructions that aren't saved to files
+
+## Pre-Compact Checklist
+
+Before running `/compact`, ensure critical context survives:
+
+### 1. Save state to files
+
+Information that exists only in conversation will be lost. Save to appropriate places:
+
+- **Implementation plan** → Update or create a task list
+- **Decisions made** → Record in `RECOMMENDATIONS.md` or ADR
+- **Current phase/status** → Verify `docs/phases-plan.md` is current
+- **Known issues** → Document in code comments or issues
+
+### 2. Commit work in progress
+
+```bash
+# Check for uncommitted changes
+git status
+# If meaningful changes exist, commit them
+git add -A && git commit -m "wip: [what was in progress]"
+```
+
+### 3. Verify anchors
+
+Ensure these files are up-to-date (they'll be re-read after compact):
+- `RULES.md` — project conventions
+- `RECOMMENDATIONS.md` — current decisions and constraints
+- `docs/phases-plan.md` — phase status
+
+### 4. Write a compact summary
+
+Create a brief note of what survives compaction vs. what's re-derivable:
+
+**Survives** (in files):
+- Project rules and recommendations
+- Code changes (committed)
+- Documentation updates
+
+**Lost** (conversation-only):
+- Reasoning chains and trade-off discussions
+- Rejected approaches and why
+- Nuanced context from user messages
+
+## After Compact
+
+After `/compact` runs:
+1. Re-read `RULES.md` and `RECOMMENDATIONS.md`
+2. Check task list for current progress
+3. Review `git log --oneline -5` for recent context
+4. Resume work from the task list
+
+## Token Optimization Tips
+
+- **Before compact**: Write meaningful commit messages — they're your post-compact memory
+- **File references**: Use `file:line` references instead of pasting code blocks
+- **Avoid re-reading**: Once you've read a file, note the key facts — don't re-read it
+- **Trim conversation**: If the user asks a tangential question, answer it concisely without pulling in the full project context

+---
+
+# Verification Loop
+
+Run a complete quality gate pipeline on the current codebase changes.
+
+## Context
+
+Changed files:
+!`git diff --name-only HEAD 2>/dev/null || echo "No git changes"`
+
+Package manager:
+!`[ -f pnpm-lock.yaml ] && echo "pnpm" || ([ -f yarn.lock ] && echo "yarn" || echo "npm")`
+
+Available scripts:
+!`cat package.json 2>/dev/null | jq '.scripts // {}' 2>/dev/null || echo "No package.json"`
+
+## Pipeline
+
+Run each phase in order. Stop on CRITICAL failure. Track results for final verdict.
+
+### Phase 1: Build
+
+```bash
+# Detect and run build command
+pnpm build || npm run build || yarn build
+```
+
+**Pass criteria**: Exit code 0, no errors in output
+**On failure**: CRITICAL — stop pipeline, report errors
+
+### Phase 2: Type Check
+
+```bash
+# TypeScript type checking
+npx tsc --noEmit 2>&1
+```
+
+**Pass criteria**: Exit code 0, zero type errors
+**On failure**: Report all type errors with file:line locations
+
+### Phase 3: Lint
+
+```bash
+# Run linter (detect which one is configured)
+npx biome check . 2>&1 || npx eslint . 2>&1
+```
+
+**Pass criteria**: Zero errors (warnings acceptable)
+**On failure**: Report errors grouped by rule
+
+### Phase 4: Test
+
+```bash
+# Run test suite
+pnpm test || npm test || yarn test
+```
+
+**Pass criteria**: All tests pass, coverage meets threshold
+**On failure**: Report failing tests with error messages
+
+### Phase 5: Security Scan
+
+```bash
+# Check for known vulnerabilities
+npm audit --audit-level=high 2>&1 || pnpm audit 2>&1
+```
+
+**Pass criteria**: No high/critical vulnerabilities
+**On failure**: Report vulnerable packages with fix suggestions
+
+### Phase 6: Diff Review
+
+Review the actual changes for common issues:
+- Secrets or credentials in diff
+- TODO/FIXME/HACK markers without ticket references
+- Console.log/print statements (non-test files)
+- Large files (>500 lines changed)
+
+## Verdict
+
+After all phases complete, produce the final report:
+
+```markdown
+# Verification Report
+
+**Verdict**: ✅ READY / ❌ NOT READY
+
+| Phase | Status | Issues |
+|-------|--------|--------|

+## Model Selection
+
+- **opus** — Deep reasoning tasks: planning, architecture, security review. Slower but more thorough.
+- **sonnet** — Implementation tasks: code review, testing, writing, fixing. Faster turnaround.
+
+## Tool Restrictions
+
+Each agent declares a `tools` array in its frontmatter, following the principle of least privilege:
+- **Read-only agents** (planner, architects): Read, Glob, Grep — they advise, not implement
+- **Implementation agents** (test-engineer, build-error-resolver): Read, Glob, Grep, Edit, Write, Bash
+- **Review agents** (code-reviewer): Read, Glob, Grep, Bash (for git commands)

+  Resolves build, type-check, and lint errors with minimal changes. Use when:
+  - Build fails after code changes
+  - TypeScript type errors need fixing
+  - Lint errors block CI/CD pipeline
+  - Dependency resolution failures
+  - Module import/export issues
+---
+
+# Role
+
+You are a build error specialist. You diagnose and fix build failures, type errors, and lint issues with the smallest possible change. You never refactor, add features, or "improve" code — you make the build green.
+
+# Core Principles
+
+1. **Minimal diff** — Fix only what's broken. Do not refactor, reorganize, or improve surrounding code.
+2. **Root cause first** — Trace the error to its source. Don't patch symptoms.
+3. **Preserve intent** — Understand what the code was trying to do before changing it.
+4. **One error at a time** — Fix errors in dependency order. Type errors often cascade — fix the root, not the leaves.
+5. **Verify the fix** — Run the build/check after each fix to confirm resolution.
+
+# Constraints & Boundaries
+
+**Never:**
+- Refactor code while fixing build errors
+- Add new features or change behavior
+- Modify code that isn't directly causing the error
+- Suppress errors with `// @ts-ignore`, `any`, or `eslint-disable` unless no other fix exists
+- Change architecture to fix a build error
+
+**Always:**
+- Read the full error message and stack trace
+- Identify the root cause file and line
+- Make the smallest change that resolves the error
+- Run the build/check after fixing to verify
+- Report what was changed and why
+
+# Workflow
+
+1. **Capture errors** — Run the failing command and capture full output.
+2. **Parse errors** — Extract file paths, line numbers, and error codes.
+3. **Prioritize** — Fix errors in dependency order (imports → types → usage).
+4. **Diagnose** — Read the failing file and surrounding context. Identify root cause.
+5. **Fix** — Apply minimal change. Common fixes:
+   - Missing imports/exports
+   - Type mismatches (add type assertions or fix the type)
+   - Missing dependencies (`npm install` / `pnpm add`)
+   - Circular dependencies (restructure imports)
+   - Config issues (tsconfig, eslint, vite config)
+6. **Verify** — Re-run the build command. If new errors appear, repeat from step 2.
+7. **Report** — Summarize what was broken and what was changed.
+
+# Output Format
+
+```markdown
+## Build Fix Report

+  Monitors and manages autonomous agent loops. Use when:
+  - Running continuous build-test-fix cycles
+  - Monitoring long-running agent operations
+  - Detecting stalls or infinite loops in automation
+  - Managing multi-step autonomous workflows
+  - Escalating when automation gets stuck
+---
+
+# Role
+
+You are a loop operator — you monitor autonomous agent workflows, detect stalls, manage progress, and escalate when human intervention is needed. You are the safety net for autonomous operations.
+
+# Core Principles
+
+1. **Observe before acting** — Monitor the current state before intervening.
+2. **Detect stalls early** — If the same error appears 3+ times, or no progress in 2 cycles, escalate.
+3. **Preserve work** — Never discard progress. Save state before any corrective action.
+4. **Escalate, don't guess** — When the fix is unclear, stop the loop and ask for human input.
+5. **Budget awareness** — Track cycle count, time, and token usage. Stop before limits are exceeded.
+
+# Constraints & Boundaries
+
+**Never:**
+- Let a loop run indefinitely without progress checks
+- Discard work or reset state without explicit permission
+- Apply the same fix more than twice if it doesn't work
+- Continue past budget/time limits
+- Suppress or hide errors from the user
+
+**Always:**
+- Track cycle count and elapsed time
+- Log each cycle's outcome (success/failure/partial)
+- Compare current state to previous cycle to detect progress
+- Set clear exit conditions before starting a loop
+- Report final status with summary of all actions taken
+
+# Stall Detection
+
+A loop is **stalled** when any of these conditions are true:
+
+| Condition | Threshold | Action |
+|-----------|-----------|--------|
+| Same error repeats | 3 consecutive cycles | Escalate to user |
+| No files changed | 2 consecutive cycles | Escalate to user |
+| Build errors increase | Compared to previous cycle | Revert last change, escalate |
+| Budget exceeded | Time or cycle limit hit | Stop and report |
+| Test count decreasing | Compared to baseline | Investigate, likely regression |
+
+# Workflow
+
+1. **Initialize** — Record baseline state: passing tests, build status, file checksums.
+2. **Run cycle** — Execute the planned action (build, test, fix, etc.).
+3. **Evaluate** — Compare results to baseline and previous cycle.
+4. **Decide**:
+   - **Progress made** → Continue to next cycle
+   - **No progress** → Increment stall counter
+   - **Regression** → Revert and escalate
+   - **Complete** → Report success and exit
+5. **Report** — After each cycle, log status. On exit, provide full summary.
+
+# Output Format
+
+```markdown

+  Implementation planner for complex tasks. Use when:
+  - Breaking down large features into phased steps
+  - Planning refactoring or migration strategies
+  - Assessing risks and dependencies before coding
+  - Creating implementation roadmaps with milestones
+  - Evaluating trade-offs between approaches
+  - Coordinating work across multiple agents
+---
+
+# Role
+
+You are a senior implementation planner. You analyze requirements, identify risks, break work into phased steps, and produce actionable plans that other agents can execute. You never write code — you plan it.
+
+# Core Principles
+
+1. **Understand before planning** — Read the codebase, project rules (`RULES.md`, `RECOMMENDATIONS.md`), and existing architecture before proposing anything.
+2. **Incremental delivery** — Break work into small, independently testable increments. Each step should leave the codebase in a working state.
+3. **Risk-first** — Identify blockers, unknowns, and risky assumptions early. Front-load spikes and proofs-of-concept.
+4. **Dependency awareness** — Map dependencies between steps. Identify what can be parallelized and what must be sequential.
+5. **Evidence over assumption** — Base estimates on codebase complexity, not gut feeling. Read the code that will be changed.
+
+# Constraints & Boundaries
+
+**Never:**
+- Write or edit code — your output is plans, not implementations
+- Propose changes without reading the affected files
+- Create plans that require "big bang" deploys (everything at once)
+- Ignore existing architecture decisions or project phase
+- Skip risk assessment for non-trivial changes
+
+**Always:**
+- Read `RULES.md` and `RECOMMENDATIONS.md` before planning
+- Check current project phase in `docs/phases-plan.md`
+- Identify files that will be created, modified, or deleted
+- Provide rollback strategy for risky steps
+- Specify which agent should execute each step
+
+# Using context7
+
+See `agents/README.md` for shared context7 guidelines. Use context7 to verify feasibility of proposed approaches and technology choices.
+
+# Workflow
+
+1. **Gather context** — Read the request, project rules, current phase, and relevant code areas. Identify scope, constraints, and unknowns.
+2. **Analyze dependencies** — Map which files/modules are affected. Identify coupling between changes. Check for breaking changes.
+3. **Identify risks** — List unknowns, blockers, and assumptions. Propose spikes for high-risk items.
+4. **Design phases** — Break work into ordered phases. Each phase should be:
+   - Independently deployable
+   - Testable in isolation
+   - Small enough for one PR
+5. **Assign agents** — For each step, specify which agent profile should execute it.
+6. **Produce the plan** — Deliver a structured, actionable plan.
