Dev Lifecycle
Coordinate the phase-specific AI DevKit skills instead of running phase details directly.
Required phase skills:
dev-worktree for feature workspace setup and resume.dev-requirements for phases 1-2: new requirement and requirements review.dev-design for phase 3: design review.dev-planning for phases 4 and 6: initial task planning and updates after implementation tasks.dev-implementation for phases 5 and 7: execute plan and check implementation.dev-testing for phase 8: write tests and verify coverage.dev-review for phase 9: final code review.
Supporting skills:
memory for reusable project knowledge during clarification.tdd for implementation tasks.verify before completing implementation, implementation checks, testing claims, and review readiness.
Startup Validation
At the beginning of every dev-lifecycle run:
- Run
npx ai-devkit@latest skill list to inspect currently installed project skills.
- Confirm the listed skills include all required phase skills and supporting skills.
- If any required skill is missing, run
npx ai-devkit@latest skill add --built-in to install all AI DevKit built-in skills. Then rerun npx ai-devkit@latest skill list.
- If installation fails or a required skill is still missing, stop and report the missing skill names and command output summary. Do not run a phase without its skill.
- Run
npx ai-devkit@latest lint to verify the configured AI docs structure.
- If working on a specific feature, run
npx ai-devkit@latest lint --feature <name>.
- If lint fails because project docs are not initialized, run
npx ai-devkit@latest init -a -e claude --built-in --yes, then rerun lint.
Plan Before Execution
Before executing any phase:
- Identify the target feature, current docs state, branch/worktree context, and likely next phase.
- Propose a concise plan that names the phase skill to use, the docs/files to read, commands to run, expected edits, and verification evidence.
- Wait for user approval before executing the plan unless the user already gave explicit approval for that exact phase execution.
- After approval, load and follow only the selected phase skill plus any explicitly required supporting skills.
Phase Routing
| Phase |
Route to |
When |
| Setup. Workspace |
dev-worktree |
Starting or resuming feature work |
| 1. New Requirement |
dev-requirements |
User wants to add a feature or start /new-requirement |
| 2. Review Requirements |
dev-requirements |
Requirements doc needs validation |
| 3. Review Design |
dev-design |
Design doc needs validation against requirements |
| 4. Create Initial Plan |
dev-planning |
Requirements, design, and testing docs are ready for task breakdown |
| 5. Execute Plan |
dev-implementation |
Ready to implement tasks from planning doc |
| 6. Update Planning |
dev-planning |
Auto-trigger after completing any implementation task |
| 7. Check Implementation |
dev-implementation |
Verify code matches design and docs |
| 8. Write Tests |
dev-testing |
Add or verify test coverage |
| 9. Code Review |
dev-review |
Final pre-push review |
Sequential flow: setup -> 1 -> 2 -> 3 -> 4 -> 5 -> 6 after each completed task -> 7 -> 8 -> 9.
Resuming Work
If the user wants to continue work on an existing feature:
- Use
dev-worktree to identify and confirm the target branch/worktree.
- Run
npx ai-devkit@latest lint --feature <feature-name> in the active context.
- Run the phase detector from the installed
dev-lifecycle skill directory:
- Resolve
<skill-dir> as the directory containing this SKILL.md.
- Run
<skill-dir>/scripts/check-status.sh <feature-name>.
- Use the suggested phase when proposing the execution plan.
Backward Transitions
Not every phase moves forward. When a phase reveals problems, route back:
- Requirements review finds fundamental gaps: return to
dev-requirements Phase 1.
- Design review finds requirements gaps: return to
dev-requirements Phase 2.
- Design review finds design flaws: stay in
dev-design and revise design.
- Implementation check finds major deviations: return to
dev-design if design is wrong, or dev-implementation if code is wrong.
- Testing reveals design flaws: return to
dev-design.
- Review finds blocking issues: return to
dev-implementation or dev-testing.
Rules
- Use
npx ai-devkit@latest lint and npx ai-devkit@latest lint --feature <name> to discover and validate the configured docs directory. Do not assume docs/ai; it is only the default.
- Read existing configured AI docs before changes. Keep diffs minimal.
- Keep feature names aligned with branch/worktree
feature-<name>.
- New feature docs come from
npx ai-devkit@latest docs init-feature <name>. Use the paths returned by the command as authoritative.
- Existing feature docs are the paths reported or validated by
npx ai-devkit@latest lint --feature <name>. If you must infer manually, first resolve the configured docs directory from .ai-devkit.json paths.docs, falling back to docs/ai.
- After each phase, summarize output and suggest the next phase.
- Do not claim completion without fresh verification evidence.
