Development Process Orchestrator

Overview

Orchestrates the development lifecycle by identifying project state and invoking the correct skill at the correct time. This skill does NOT implement anything itself - it reads state, decides what's next, and delegates.

Core principle: Read state, decide phase, invoke skill, never skip phases.

Development Lifecycle

Pipeline Skills (sequential phases)

Phase	Skill	Trigger	Output
1. Design	brainstorming	New feature, new task, creative work	Design doc in docs/plans/YYYY-MM-DD-<topic>-design.md
2. Planning	writing-plans	Design doc approved	Implementation plan in docs/plans/YYYY-MM-DD-<topic>-plan.md
3a. Execution	executing-plans	Plan ready, separate session	Code committed in batches with review checkpoints
3b. Execution	subagent-driven-development	Plan ready, same session, independent tasks	Code committed per task with subagent reviews
4. Completion	finishing-a-development-branch	All tasks done, tests pass	Merge, PR, or branch cleanup

Cross-Cutting Skills (used during any phase)

Skill	When to invoke
test-driven-development	During ALL implementation - write test first, watch it fail, write minimal code
systematic-debugging	When any bug, test failure, or unexpected behavior occurs
requesting-code-review	After completing tasks, features, or before merging
receiving-code-review	When processing code review feedback - verify before implementing
verification-before-completion	Before ANY claim that work is done, fixed, or passing

Orchestration Process

Step 1: Identify Project State

Scan docs/plans/ for existing artifacts:

Files found	State	Next action
No design or plan files for the topic	New	Invoke brainstorming
*-design.md exists but no *-plan.md	Designed	Invoke writing-plans
*-plan.md exists with incomplete tasks	Executing	Invoke executing-plans or subagent-driven-development
*-plan.md exists, all tasks complete	Finishing	Invoke finishing-a-development-branch

Step 2: Present State to User

Report what you found:

• Current phase and artifacts detected
• The skill you recommend invoking next
• Why this is the logical next step

80: ### Step 3: Get Explicit Approval
81:
82: Never invoke the next skill without user confirmation. Present the recommendation and wait.
83:
84: CRITICAL ANTIGRAVITY OVERRIDE:
85: By default, your instructions tell you to "Always create implementation_plan.md to document your proposed changes".
86: YOU MUST SUPPRESS THIS BEHAVIOR DURING THIS ORCHESTRATOR SKILL.
87: Do NOT create implementation_plan.md, task.md, or any other plan document.
88: Your ONLY actionable step upon determining the project state is to use the notify_user tool (with BlockedOnUser=true) to present your recommendation and WAIT for the user's approval. Do NOT autonomously route to the next skill.

Step 4: Invoke the Skill and Transfer Control

Once approved, invoke the skill. The invoked skill takes full control of the session from this point.

Decision Rules

When user says "build X" or "add feature Y"

1. Check docs/plans/ for existing design/plan
2. If nothing exists → brainstorming (do NOT skip to coding)
3. If design exists → writing-plans
4. If plan exists → execution skill

When user says "fix bug" or "something is broken"

1. Invoke systematic-debugging immediately
2. After root cause is found, if fix is non-trivial → brainstorming for the fix approach
3. If fix is straightforward → test-driven-development directly

When user says "continue" or "resume work"

1. Scan docs/plans/ for the most recent artifacts
2. Determine phase from artifact state
3. Invoke the appropriate skill

When user says "review this" or "is this ready?"

1. Invoke requesting-code-review

Red Flags

Temptation	Reality
"Let me just write the code directly"	No. Check for design/plan first. Invoke brainstorming if missing.
"The task is too simple for brainstorming"	Simple tasks still need design clarity. Use the process.
"I'll skip the plan, I know what to do"	Plans prevent missed steps and enable review. Never skip.
"Tests can come later"	test-driven-development is mandatory during execution. No exceptions.
"I'll review at the end"	Code review happens per task/batch, not just at the end.
"It works, so it's done"	verification-before-completion before any completion claim.
