Simple Tasks — Break Down a Feature into an Ordered Task List

You are creating an ordered task list for a feature. Your job is to produce an issues.json file inside docs/<feature-name>/ that gives an AI coding agent (or a human developer) a clear, prioritized work queue — each task small enough to implement in a single session, ordered so that dependencies are respected and the feature comes together incrementally.

This skill consumes the output of simple-spec and simple-design (and optionally simple-visual). It pairs with simple-implement, which picks tasks from this list one at a time, and simple-run, which orchestrates the loop.

Folder convention

All feature artifacts live in docs/<feature-name>/:

docs/
  index.json              ← feature manifest (created/updated by this skill)
  visual.md               ← from simple-visual (app-level, optional)
  <feature-name>/
    spec.md               ← from simple-spec
    spec/                 ← optional detail files (from simple-spec, if spec.md was split)
    design.md             ← from simple-design
    design/               ← optional detail files (from simple-design, if design.md was split)
    issues.json           ← THIS SKILL'S OUTPUT
    progress-log.md       ← created by simple-implement

The <feature-name> token is a short kebab-case identifier (e.g., auth, workspace-sharing, csv-export) that ties all artifacts together by directory.

Workflow

1. Gather context

Start by collecting all available planning documents before asking the user anything.

Required inputs:

• Read docs/<feature-name>/spec.md — this is your primary source for what to build, user stories, acceptance criteria, and edge cases.
• Read docs/<feature-name>/design.md — this tells you how to build it: architecture, data flow, interfaces, affected components, testing strategy.
• If spec.md or design.md indexes child detail files (a spec/ or design/ subfolder), read those too. They hold the page-level detail you need to size tasks accurately and to point each task at the right section.

Optional inputs:

• Read docs/visual.md if it exists — this is the app-level visual design system. UI/visual tasks need this context.
• Scan the codebase to understand its current state, conventions, and complexity. This helps you size tasks accurately and identify prerequisites.

If inputs are missing:

• If the user hasn't specified a feature name, check docs/ for existing feature subdirectories and ask which one to break down. If there's only one, use it.
• If spec.md or design.md doesn't exist, tell the user and suggest running simple-spec or simple-design first. You can still proceed if the user provides enough context directly, but the output quality will be lower — say so explicitly.

2. Ask follow-up questions (only if needed)

After reading the planning docs, assess whether you have enough to produce a good breakdown. Common gaps:

• Granularity preference: "The design describes 3 major components. Should each be one task, or should I break them into smaller units (e.g., data model, API, UI separately)?"
• Priority signals: "The spec has 5 user stories — are any higher priority than others, or should I order by technical dependency only?"
• Scope confirmation: "The spec marks X as out-of-scope, but the design references it. Should I include it or flag it as a discrepancy?"
• Testing expectations: "Should testing be a separate task per component, or bundled into each implementation task?"

Keep it to one round of 1-4 focused questions. If you can make reasonable choices from the planning docs, do so — you can note assumptions in the task descriptions.

3. Generate the task list

Read the template at references/issues_template.json in this skill's directory. Use it as the structural guide for your output.

Required fields for every task:

Field	Type	Description
id	string	TASK-<feature>-001 format, zero-padded, sequential
type	string	"story" | "bug" | "task" | "chore"
title	string	Short imperative summary (e.g., "Add sharing permissions model")
description	string	Concise but sufficient detail for an agent to implement
acceptance_criteria	array of string	Success conditions — specific and verifiable
status	string	Always "todo" when generated by this skill
priority	integer	1 = highest. Determines execution order
depends_on	array of string	IDs of tasks that must complete first. Empty if none

Optional fields — add these when the project complexity warrants it:

• estimated_effort: "small" | "medium" | "large" — relative sizing
• tags: array of strings for categorization (e.g., ["backend", "database"])
• notes: string for context that doesn't fit elsewhere
• blocked_reason: string explaining why a task is blocked (used by simple-implement)
• files_likely_affected: array of file paths the task will probably touch

The agent is free to add other fields as needed for complex projects. The required fields are the contract that simple-implement depends on.

Key principles:

• Order by dependency, then by priority. Tasks with no dependencies and high priority come first. Tasks that depend on others come after their dependencies. The priority field is the tiebreaker when dependencies are equal.

• Each task should be completable in one session. If a task feels like it would take more than a few hours of focused work, break it into smaller pieces. An agent should be able to pick up a single task, implement it, verify it, and move on.

• Tasks should be independently verifiable. Each task's acceptance criteria should be testable without completing subsequent tasks. This means the feature builds up incrementally — each task leaves the codebase in a working state.

• Reference the planning docs, don't duplicate them. Task descriptions should point back to specific sections of the spec or design (e.g., "Implement the sharing permissions model described in design.md § Proposed storage changes", or a child file such as "design/permissions.md § Schema changes"). Don't copy entire sections.

• Include setup and testing tasks. Don't skip the boring stuff: database migrations, config changes, test scaffolding, CI updates. These are tasks too and they often block other work.

• Be specific about what "done" means. "Implement the API endpoint" is vague. "Implement POST /api/workspaces/:id/share — validates input, creates sharing record, returns 201 with sharing details. Returns 409 if already shared with that user." is verifiable.

• Map user stories to tasks, but don't force a 1:1 mapping. A single user story might require multiple tasks (data model + API + UI). Multiple simple stories might be one task. The design document's "affected components" and "planned changes" sections are usually the best guide for task boundaries.

4. Save the output

• Save the task list to docs/<feature-name>/issues.json.
• Update (or create) docs/index.json at the project root. This is a lightweight manifest:

{
  "features": {
    "<feature-name>": {
      "status": "tasks_ready",
      "path": "docs/<feature-name>/"
    }
  }
}

Valid feature statuses: "planning", "spec_ready", "design_ready", "tasks_ready", "in_progress", "done".

• Tell the user the file path and give a brief summary: how many tasks, what the critical path looks like, and any assumptions you made.

5. Suggest next step

Let the user know the task list is ready for implementation. Mention that they can:

• Use simple-implement to work through tasks one at a time (manual control).
• Use simple-run to automatically loop through all tasks until the feature is complete.
• Review and adjust the task list before starting — reorder, split, merge, or remove tasks as needed. The JSON format makes this easy.

Important notes

• This skill produces a task breakdown, not a spec or design — focus on what work units to do and in what order, not requirements or architecture. If you find yourself writing user stories or proposing technical approaches, reference the planning docs instead.
• Keep the task count proportional to complexity — a small feature might have 3-5 tasks, a large one 15-25. Don't inflate or compress artificially.
• If the spec and design disagree, flag it as a discrepancy for the user to resolve rather than silently picking one.
• All tasks start with status: "todo" — only simple-implement changes task status.
• depends_on forms a DAG — no circular dependencies. If two tasks are truly co-dependent, merge them into one.
