name	sdlc-plan
description	Break specs into ordered tasks with acceptance criteria. Use after sdlc-spec to create executable task breakdown.

Model auto-switch: Extension switches to plan-tier model automatically.

Rules: Assign task types so executor loads correct rules from docs/rules/.

SDLC Plan

Overview

Transform spec into ordered tasks with testable criteria, dependencies, and scope estimates.

Dependency: Requires pi-memctx.

Process

Step 0: Check Approval

plan_tracker_ide:
  action: check_approval
  phase: plan

If APPROVED, skip to tracker status and handoff. Do not re-ask for plan confirmation.

Step 1: Load Spec

memctx_search:
  query: "spec {feature}"
  mode: keyword

Or read from docs/specs/{path}/spec.md.

Step 2: Create Tasks

For each task, create docs/specs/{feature}/tasks/NN-{name}.md:

# Task NN: {Name}

**Scope:** S | M | L
**Type:** backend | frontend | mixed
**Dependencies:** [Task numbers]

## Description
[What this accomplishes]

## Acceptance Criteria
- [ ] [Criterion 1]
- [ ] [Criterion 2]

## Files
- Create: `path/to/new.ts`
- Modify: `path/to/existing.ts`
- Test: `tests/path.ts`

## Steps
1. [Specific action]
2. [Specific action]

## Verification
- Test: `npm test -- {pattern}`

Task Types

Type	Executor Rules
backend	TDD mandatory (red→green→refactor)
frontend	Anti-slop mandatory, reference existing
mixed	Backend: TDD, Frontend: anti-slop

Step 3: Sync to memctx

memctx_save:
  type: observation
  title: {feature} Tasks
  path: 60-observations/{feature}-tasks.md
  tags: [sdlc, plan, {feature}]

Step 4: Init Tracker

plan_tracker_ide:
  action: init
  feature: "{feature}"
  specPath: "docs/specs/{feature}/spec.md"
  tasks:
    - name: "Task 01: {name}"
      type: backend
      criteria: ["criterion 1", "criterion 2"]
    - name: "Task 02: {name}"
      type: frontend
      criteria: ["criterion 1"]

Step 5: Approve Phase

plan_tracker_ide:
  action: approve
  phase: plan
  summary: "{N} tasks created for {feature}"

Step 6: Commit

git add docs/specs/{feature}/tasks/
git commit -m "docs: add task breakdown for {feature}"

Task Granularity

Good: 15-60 min, single responsibility, independently testable.

Split if: Multiple unrelated changes, >3 files, >2 hours.

Merge if: <5 min, tightly coupled.

Handoff

Plan complete: {N} tasks in docs/specs/{feature}/tasks/
