description: Systematic implementation using APEX methodology (Analyze-Plan-Execute-eXamine) with parallel agents, self-validation, and optional adversarial review. Use when implementing features, fixing bugs, or making code changes that benefit from structured workflow.
argument-hint: "[-a] [-x] [-s] [-t] [-b] [-pr] [-i] [-r ] "
metadata:
mcpmarket-version: 1.0.0
/apex add authentication middleware
Recommended workflow (autonomous with save):
/apex -a -s implement user registration
With adversarial review:
/apex -a -x -s fix login bug
Flags:
-a(auto): Skip confirmations-s(save): Save outputs to.claude/output/apex/-x(examine): Include adversarial code review-t(test): Create and run tests-pr(pull-request): Create PR at end
See <parameters> for complete flag list.

<parsing_rules>
**Flag parsing:**
1. Defaults loaded from `steps/step-00-init.md` `<defaults>` section
2. Command-line flags override defaults (enable with lowercase `-x`, disable with uppercase `-X`)
3. Flags removed from input, remainder becomes `{task_description}`
4. Task ID generated as `NN-kebab-case-description`
For detailed parsing algorithm, see `steps/step-00-init.md`.
</parsing_rules>
</parameters>
<output_structure>
**When `{save_mode}` = true:**
All outputs saved to PROJECT directory (where Claude Code is running):
.claude/output/apex/{task-id}/ ├── 00-context.md # Params, user request, timestamp ├── 01-analyze.md # Analysis findings ├── 02-plan.md # Implementation plan ├── 03-execute.md # Execution log ├── 04-validate.md # Validation results ├── 05-examine.md # Review findings (if -x) ├── 06-resolve.md # Resolution log (if -x) ├── 07-tests.md # Test analysis and creation (if --test) ├── 08-run-tests.md # Test runner log (if --test) └── 09-finish.md # Workflow finish and PR creation (if --pull-request)
**00-context.md structure:**
```markdown
# APEX Task: {task_id}
**Created:** {timestamp}
**Task:** {task_description}
## Flags
- Auto mode: {auto_mode}
- Examine mode: {examine_mode}
- Save mode: {save_mode}
- Test mode: {test_mode}
## User Request
{original user input}
## Acceptance Criteria
- [ ] AC1: {inferred criterion}
- [ ] AC2: {inferred criterion}
When provided, step-00 will:
- Locate the task folder in
.claude/output/apex/ - Restore state from
00-context.md - Find the last completed step
- Continue from the next step
Supports partial matching (e.g., -r 01 finds 01-add-auth-middleware).
For implementation details, see steps/step-00-init.md.

FIRST ACTION: Load steps/step-00-init.md
Step 00 handles:
- Flag parsing (-a, -x, -s, -r, --test)
- Resume mode detection and task lookup
- Output folder creation (if save_mode)
- 00-context.md creation (if save_mode)
- State variable initialization
After initialization, step-00 loads step-01-analyze.md.
| Step | File | Purpose |
|---|---|---|
| 00 | steps/step-00-init.md |
Parse flags, create output folder, initialize state |
| 01 | steps/step-01-analyze.md |
Smart context gathering with 1-10 parallel agents based on complexity |
| 02 | steps/step-02-plan.md |
File-by-file implementation strategy |
| 03 | steps/step-03-execute.md |
Todo-driven implementation |
| 04 | steps/step-04-validate.md |
Self-check and validation |
| 05 | steps/step-05-examine.md |
Adversarial code review (optional) |
| 06 | steps/step-06-resolve.md |
Finding resolution (optional) |
| 07 | steps/step-07-tests.md |
Test analysis and creation (if --test) |
| 08 | steps/step-08-run-tests.md |
Test runner loop until green (if --test) |
| 09 | steps/step-09-finish.md |
Create pull request (if --pull-request) |
- Load one step at a time - Only load the current step file
- ULTRA THINK before major decisions
- Persist state variables across all steps
- Follow next_step directive at end of each step
- Save outputs if
{save_mode}= true (append to step file) - Use parallel agents for independent exploration tasks
🧠 Smart Agent Strategy in Analyze Phase
The analyze phase (step-01) uses adaptive agent launching (unless economy_mode):
Available agents:
explore-codebase- Find existing patterns, files, utilitiesexplore-docs- Research library docs (use when unfamiliar with API)websearch- Find approaches, best practices, gotchas
Launch 1-10 agents based on task complexity:
| Complexity | Agents | When |
|---|---|---|
| Simple | 1-2 | Bug fix, small tweak |
| Medium | 2-4 | New feature in familiar stack |
| Complex | 4-7 | Unfamiliar libraries, integrations |
| Major | 6-10 | Multiple systems, many unknowns |
BE SMART: Analyze what you actually need before launching. Don't over-launch for simple tasks, don't under-launch for complex ones.
Step-00 runs scripts/setup-templates.sh to initialize all output files from templates/ directory.
Each step then:
- Run
scripts/update-progress.sh {task_id} {step_num} {step_name} "in_progress" - Append findings/outputs to the pre-created step file
- Run
scripts/update-progress.sh {task_id} {step_num} {step_name} "complete"
Template system benefits:
- Reduces token usage by ~75% (1,350 tokens saved per workflow)
- Templates in
templates/directory (not inline in steps) - Scripts handle progress tracking automatically
- See
templates/README.mdfor details
- Each step loaded progressively
- All validation checks passing
- Outputs saved if
{save_mode}enabled - Tests passing if
{test_mode}enabled - Clear completion summary provided
