ce:work	Execute work plans efficiently while maintaining quality and finishing features	[plan file, specification, or todo file path]

Work Plan Execution Command

Execute a work plan efficiently while maintaining quality and finishing features.

Introduction

This command takes a work document (plan, specification, or todo file) and executes it systematically. The focus is on shipping complete features by understanding requirements quickly, following existing patterns, and maintaining quality throughout.

Input Document

<input_document> #$ARGUMENTS </input_document>

Execution Workflow

Phase 1: Quick Start

Read Plan and Clarify
- Read the work document completely
- Treat the plan as a decision artifact, not an execution script
- If the plan includes sections such as Implementation Units, Work Breakdown, Requirements Trace, Files, Test Scenarios, or Verification, use those as the primary source material for execution
- Check for Execution note on each implementation unit — these carry the plan's execution posture signal for that unit (for example, test-first or characterization-first). Note them when creating tasks.
- Check for a Deferred to Implementation or Implementation-Time Unknowns section — these are questions the planner intentionally left for you to resolve during execution. Note them before starting so they inform your approach rather than surprising you mid-task
- Check for a Scope Boundaries section — these are explicit non-goals. Refer back to them if implementation starts pulling you toward adjacent work
- Review any references or links provided in the plan
- If the user explicitly asks for TDD, test-first, or characterization-first execution in this session, honor that request even if the plan has no Execution note
- If anything is unclear or ambiguous, ask clarifying questions now
- Get user approval to proceed
- Do not skip this - better to ask questions now than build the wrong thing
Setup Environment

First, check the current branch:
```
current_branch=$(git branch --show-current)
default_branch=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')

# Fallback if remote HEAD isn't set
if [ -z "$default_branch" ]; then
  default_branch=$(git rev-parse --verify origin/main >/dev/null 2>&1 && echo "main" || echo "master")
fi
```
If already on a feature branch (not the default branch):
- Ask: "Continue working on [current_branch], or create a new branch?"
- If continuing, proceed to step 3
- If creating new, follow Option A or B below
If on the default branch, choose how to proceed:

Option A: Create a new branch
```
git pull origin [default_branch]
git checkout -b feature-branch-name
```
Use a meaningful name based on the work (e.g., feat/user-authentication, fix/email-validation).

Option B: Use a worktree (recommended for parallel development)
```
skill: git-worktree
# The skill will create a new branch from the default branch in an isolated worktree
```
Option C: Continue on the default branch
- Requires explicit user confirmation
- Only proceed after user explicitly says "yes, commit to [default_branch]"
- Never commit directly to the default branch without explicit permission
Recommendation: Use worktree if:
- You want to work on multiple features simultaneously
- You want to keep the default branch clean while experimenting
- You plan to switch between branches frequently
Create Todo List
- Use your available task tracking tool (e.g., TodoWrite, task lists) to break the plan into actionable tasks
- Derive tasks from the plan's implementation units, dependencies, files, test targets, and verification criteria
- Carry each unit's Execution note into the task when present
- For each unit, read the Patterns to follow field before implementing — these point to specific files or conventions to mirror
- Use each unit's Verification field as the primary "done" signal for that task
- Do not expect the plan to contain implementation code, micro-step TDD instructions, or exact shell commands
- Include dependencies between tasks
- Prioritize based on what needs to be done first
- Include testing and quality check tasks
- Keep tasks specific and completable

Choose Execution Strategy

After creating the task list, decide how to execute based on the plan's size and dependency structure:

Strategy	When to use
Inline	1-2 small tasks, or tasks needing user interaction mid-flight
Serial subagents	3+ tasks with dependencies between them. Each subagent gets a fresh context window focused on one unit — prevents context degradation across many tasks
Parallel subagents	3+ tasks where some units have no shared dependencies and touch non-overlapping files. Dispatch independent units simultaneously, run dependent units after their prerequisites complete

Subagent dispatch uses your available subagent or task spawning mechanism. For each unit, give the subagent:

The full plan file path (for overall context)
The specific unit's Goal, Files, Approach, Execution note, Patterns, Test scenarios, and Verification
Any resolved deferred questions relevant to that unit

After each subagent completes, update the plan checkboxes and task list before dispatching the next dependent unit.

For genuinely large plans needing persistent inter-agent communication (agents challenging each other's approaches, shared coordination across 10+ tasks), see Swarm Mode below which uses Agent Teams.

Phase 2: Execute

Task Execution Loop

For each task in priority order:

while (tasks remain):
  - Mark task as in-progress
  - Read any referenced files from the plan
  - Look for similar patterns in codebase
  - Implement following existing conventions
  - Write tests for new functionality
  - Run System-Wide Test Check (see below)
  - Run tests after changes
  - Mark task as completed
  - Evaluate for incremental commit (see below)

When a unit carries an Execution note, honor it. For test-first units, write the failing test before implementation for that unit. For characterization-first units, capture existing behavior before changing it. For units without an Execution note, proceed pragmatically.

Guardrails for execution posture:

Do not write the test and implementation in the same step when working test-first
Do not skip verifying that a new test fails before implementing the fix or feature
Do not over-implement beyond the current behavior slice when working test-first
Skip test-first discipline for trivial renames, pure configuration, and pure styling work

System-Wide Test Check — Before marking a task done, pause and ask:

Question	What to do
What fires when this runs? Callbacks, middleware, observers, event handlers — trace two levels out from your change.	Read the actual code (not docs) for callbacks on models you touch, middleware in the request chain, `after_*` hooks.
Do my tests exercise the real chain? If every dependency is mocked, the test proves your logic works in isolation — it says nothing about the interaction.	Write at least one integration test that uses real objects through the full callback/middleware chain. No mocks for the layers that interact.
Can failure leave orphaned state? If your code persists state (DB row, cache, file) before calling an external service, what happens when the service fails? Does retry create duplicates?	Trace the failure path with real objects. If state is created before the risky call, test that failure cleans up or that retry is idempotent.
What other interfaces expose this? Mixins, DSLs, alternative entry points (Agent vs Chat vs ChatMethods).	Grep for the method/behavior in related classes. If parity is needed, add it now — not as a follow-up.
Do error strategies align across layers? Retry middleware + application fallback + framework error handling — do they conflict or create double execution?	List the specific error classes at each layer. Verify your rescue list matches what the lower layer actually raises.

When to skip: Leaf-node changes with no callbacks, no state persistence, no parallel interfaces. If the change is purely additive (new helper method, new view partial), the check takes 10 seconds and the answer is "nothing fires, skip."

When this matters most: Any change that touches models with callbacks, error handling with fallback/retry, or functionality exposed through multiple interfaces.

Incremental Commits

After completing each task, evaluate whether to create an incremental commit:

Commit when...	Don't commit when...
Logical unit complete (model, service, component)	Small part of a larger unit
Tests pass + meaningful progress	Tests failing
About to switch contexts (backend → frontend)	Purely scaffolding with no behavior
About to attempt risky/uncertain changes	Would need a "WIP" commit message

Heuristic: "Can I write a commit message that describes a complete, valuable change? If yes, commit. If the message would be 'WIP' or 'partial X', wait."

If the plan has Implementation Units, use them as a starting guide for commit boundaries — but adapt based on what you find during implementation. A unit might need multiple commits if it's larger than expected, or small related units might land together. Use each unit's Goal to inform the commit message.

Commit workflow:

# 1. Verify tests pass (use project's test command)
# Examples: bin/rails test, npm test, pytest, go test, etc.

# 2. Stage only files related to this logical unit (not `git add .`)
git add <files related to this logical unit>

# 3. Commit with conventional message
git commit -m "feat(scope): description of this unit"

Handling merge conflicts: If conflicts arise during rebasing or merging, resolve them immediately. Incremental commits make conflict resolution easier since each commit is small and focused.

Note: Incremental commits use clean conventional messages without attribution footers. The final Phase 4 commit/PR includes the full attribution.

Follow Existing Patterns
- The plan should reference similar code - read those files first
- Match naming conventions exactly
- Reuse existing components where possible
- Follow project coding standards (see AGENTS.md; use CLAUDE.md only if the repo still keeps a compatibility shim)
- When in doubt, grep for similar implementations
Test Continuously
- Run relevant tests after each significant change
- Don't wait until the end to test
- Fix failures immediately
- Add new tests for new functionality
- Unit tests with mocks prove logic in isolation. Integration tests with real objects prove the layers work together. If your change touches callbacks, middleware, or error handling — you need both.
Simplify as You Go

After completing a cluster of related implementation units (or every 2-3 units), review recently changed files for simplification opportunities — consolidate duplicated patterns, extract shared helpers, and improve code reuse and efficiency. This is especially valuable when using subagents, since each agent works with isolated context and can't see patterns emerging across units.

Don't simplify after every single unit — early patterns may look duplicated but diverge intentionally in later units. Wait for a natural phase boundary or when you notice accumulated complexity.

If a /simplify skill or equivalent is available, use it. Otherwise, review the changed files yourself for reuse and consolidation opportunities.
Figma Design Sync (if applicable)

For UI work with Figma designs:
- Implement components following design specs
- Use figma-design-sync agent iteratively to compare
- Fix visual differences identified
- Repeat until implementation matches design
Track Progress
- Keep the task list updated as you complete tasks
- Note any blockers or unexpected discoveries
- Create new tasks if scope expands
- Keep user informed of major milestones

Phase 3: Quality Check

Run Core Quality Checks

Always run before submitting:

# Run full test suite (use project's test command)
# Examples: bin/rails test, npm test, pytest, go test, etc.

# Run linting (per AGENTS.md)
# Use linting-agent before pushing to origin

Consider Reviewer Agents (Optional)

Use for complex, risky, or large changes. Read agents from compound-engineering.local.md frontmatter (review_agents). If no settings file, invoke the setup skill to create one.

Run configured agents in parallel with Task tool. Present findings and address critical issues.
Final Validation
- All tasks marked completed
- All tests pass
- Linting passes
- Code follows existing patterns
- Figma designs match (if applicable)
- No console errors or warnings
- If the plan has a Requirements Trace, verify each requirement is satisfied by the completed work
- If any Deferred to Implementation questions were noted, confirm they were resolved during execution
Prepare Operational Validation Plan (REQUIRED)
- Add a ## Post-Deploy Monitoring & Validation section to the PR description for every change.
- Include concrete:
  - Log queries/search terms
  - Metrics or dashboards to watch
  - Expected healthy signals
  - Failure signals and rollback/mitigation trigger
  - Validation window and owner
- If there is truly no production/runtime impact, still include the section with: No additional operational monitoring required and a one-line reason.

Phase 4: Ship It

Create Commit

git add .
git status  # Review what's being committed
git diff --staged  # Check the changes

# Commit with conventional format
git commit -m "$(cat <<'EOF'

Update Plan Status

If the input document has YAML frontmatter with a status field, update it to completed:
```
status: active  →  status: completed
```
Notify User
- Summarize what was completed
- Link to PR
- Note any follow-up work needed
- Suggest next steps if applicable

Swarm Mode with Agent Teams (Optional)

For genuinely large plans where agents need to communicate with each other, challenge approaches, or coordinate across 10+ tasks with persistent specialized roles, use agent team capabilities if available (e.g., Agent Teams in Claude Code, multi-agent workflows in Codex).

Agent teams are typically experimental and require opt-in. Do not attempt to use agent teams unless the user explicitly requests swarm mode or agent teams, and the platform supports it.

When to Use Agent Teams vs Subagents

Agent Teams	Subagents (standard mode)
Agents need to discuss and challenge each other's approaches	Each task is independent — only the result matters
Persistent specialized roles (e.g., dedicated tester running continuously)	Workers report back and finish
10+ tasks with complex cross-cutting coordination	3-8 tasks with clear dependency chains
User explicitly requests "swarm mode" or "agent teams"	Default for most plans

Most plans should use subagent dispatch from standard mode. Agent teams add significant token cost and coordination overhead — use them when the inter-agent communication genuinely improves the outcome.

Agent Teams Workflow

Create team — use your available team creation mechanism
Create task list — parse Implementation Units into tasks with dependency relationships
Spawn teammates — assign specialized roles (implementer, tester, reviewer) based on the plan's needs. Give each teammate the plan file path and their specific task assignments
Coordinate — the lead monitors task completion, reassigns work if someone gets stuck, and spawns additional workers as phases unblock
Cleanup — shut down all teammates, then clean up the team resources

Key Principles

Start Fast, Execute Faster

Get clarification once at the start, then execute
Don't wait for perfect understanding - ask questions and move
The goal is to finish the feature, not create perfect process

The Plan is Your Guide

Work documents should reference similar code and patterns
Load those references and follow them
Don't reinvent - match what exists

Test As You Go

Run tests after each change, not at the end
Fix failures immediately
Continuous testing prevents big surprises

Quality is Built In

Follow existing patterns
Write tests for new code
Run linting before pushing
Use reviewer agents for complex/risky changes only

Ship Complete Features

Mark all tasks completed before moving on
Don't leave features 80% done
A finished feature that ships beats a perfect feature that doesn't

Quality Checklist

Before creating PR, verify:

All clarifying questions asked and answered
All tasks marked completed
Tests pass (run project's test command)
Linting passes (use linting-agent)
Code follows existing patterns
Figma designs match implementation (if applicable)
Before/after screenshots captured and uploaded (for UI changes)
Commit messages follow conventional format
PR description includes Post-Deploy Monitoring & Validation section (or explicit no-impact rationale)
PR description includes summary, testing notes, and screenshots
PR description includes Compound Engineered badge with accurate model, harness, and version

When to Use Reviewer Agents

Don't use by default. Use reviewer agents only when:

Large refactor affecting many files (10+)
Security-sensitive changes (authentication, permissions, data access)
Performance-critical code paths
Complex algorithms or business logic
User explicitly requests thorough review

For most features: tests + linting + following patterns is sufficient.

Common Pitfalls to Avoid

Analysis paralysis - Don't overthink, read the plan and execute
Skipping clarifying questions - Ask now, not after building wrong thing
Ignoring plan references - The plan has links for a reason
Testing at the end - Test continuously or suffer later
Forgetting to track progress - Update task status as you go or lose track of what's done
80% done syndrome - Finish the feature, don't move on early
Over-reviewing simple changes - Save reviewer agents for complex work
