description	Create implementation tasks from specs (full lane)

Tasks

Create implementation tasks for the change set. Full lane only—vibe/bug lanes skip this and use ae-sdd-plan.

Required Skills

• spec-driven-development (state management, lane detection, task operations)

Inputs

[!IMPORTANT] Resolve the change set by running ls changes/ | grep -v archive/. If exactly one directory exists, use it. Only prompt the user when multiple change sets are present.

Instructions

1. Load spec-driven-development skill. Read state from changes/<name>/state.toml. Apply state entry check per skill guidelines.

2. Lane check: If lane is vibe or bug, redirect to ae-sdd-plan per skill guidelines.

3. Read proposal, specs from changes/<name>/specs/, and thoughts from changes/<name>/thoughts/.

4. This is a dialogue. Before creating tasks, present your breakdown thinking:

   • How you'll map spec requirements to tasks
   • Why you're grouping them this way
   • What task order maintains system stability
   • Ask for feedback on granularity and flow.

5. Create tasks by editing tasks.toml to add for each task:

   • Title (short, descriptive)
   • Description (what the task accomplishes)
   • spec_requirements entries grouped by source spec file
   • Requirement strings mapped from spec lines using EARS syntax
   • Status: pending

   Required structure:

   [[task]]
   name = "task-name"
   title = "Task title"
   description = "What this task accomplishes"
   status = "pending"
   
   [[task.spec_requirements]]
   spec = "changes/<name>/specs/<file>.md"
   requirements = [
     "When <condition>, the system SHALL <behavior>",
     "If <trigger>, the system SHALL <behavior>"
   ]
   

6. Task ordering principles:

   • Foundations first (models, types, codegen)
   • Then vertical implementation slices
   • Then integration
   • Then validation

7. Task constraints:

   • Every task must be completable in one session
   • Independently testable
   • Leave the system in a committable state

8. Do not update phase status in this command. When the user wants to proceed, suggest ae-sdd-next <name>.

Examples

Full lane, task breakdown dialogue:

Input: None (full lane, single change "user-reg")
Output: Present breakdown: "I'll scaffold DB models first, then vertical slices. 3 tasks total."
       User approves. Create tasks in tasks.toml for: foundation, implementation, validation.

Task shape sample:

[[task]]
name = "foundation"
title = "Foundation - DB models and migrations"
description = "Add user tables and migrations to support registration."
status = "pending"

[[task.spec_requirements]]
spec = "changes/user-reg/specs/registration.md"
requirements = [
  "When a new user is created, the system SHALL persist profile fields.",
  "When validation fails, the system SHALL return field errors."
]

[[task.spec_requirements]]
spec = "changes/user-reg/specs/security.md"
requirements = [
  "If password policy fails, the system SHALL reject account creation."
]

Wrong lane detected:

Input: "vibe-lane" (not full lane)
Output: "Vibe lane should use ae-sdd-plan instead. Redirecting."
