Breaking Specs into Actions: specsfy-05-tasks for Agents
Manage task decomposition, dependencies, and vertical slices directly in spec.md. Learn how this skill keeps agents aligned with the single source of truth.
Where this fits
You've just finished writing a detailed spec.md for a new feature. The next step is turning that specification into a list of actionable, ordered tasks with clear dependencies. Instead of manually copying IDs or risking divergence between the spec and a separate task list, your agent can use specsfy-05-tasks to populate the 14. Tarefas section directly in the source file. This is especially useful when you're working with a strict RED-GREEN-REFACTOR workflow and need to plan or reprioritize tasks after each test failure.
Why agents benefit
- Single source of truth: Agents edit the
14. Tarefassection insidespec.md—no separate task files that can drift out of sync. - Dependency ordering: The skill understands how to sequence tasks by the IDs already defined in the spec, so agents can produce a logically ordered backlog.
- Vertical slice planning: It helps group tasks into minimal end-to-end slices, making each iteration testable and shippable.
- Automatic transition handling: When a spec is promoted after RED, the skill announces pending work and can hand off to the next responsible skill without asking for confirmation.
- Scope discipline: It explicitly avoids writing code or marking work complete, preventing agents from overstepping into execution phases.
Practical scenarios
Planning a new feature from scratch
You've drafted a 5-page spec for a payment integration. The agent uses specsfy-05-tasks to break it into 12 tasks, assigns each a dependency, and groups them into three vertical slices: auth, charge, and refund. The result is a clean backlog ready for the first RED cycle.
Re-planning after a RED failure
Your agent just finished a test that failed because a pre-requisite task was skipped. The skill detects the mismatch, updates the task order, and announces the transition to the next skill—keeping momentum without manual intervention.
Maintaining a long-lived spec
Months later, you add a new requirement to the spec. The agent re-runs the skill to insert the new task, re-orders dependent tasks, and updates the 14. Tarefas section—ensuring the source of truth remains accurate without touching stale task boards.
Add it to your agent workflow
Install directly and invoke when you need to decompose or update tasks:
npx skills add promovaweb/specsfy --skill specsfy-05-tasks
Then, in your agent prompt, you can say: "Break the spec into ordered tasks with dependencies, updating section 14 of spec.md." The skill will handle the rest, respecting the single source of truth.
Compare before adopting
Before committing, compare against alternatives:
- Quality signals: Check the skill's README for clarity on scope boundaries and transitions—does it enforce the "no code" rule?
- Maintenance freshness: The GitHub repo (promovaweb/specsfy) has 60+ stars; look for recent commits and issue responses.
- Alternatives: Some workflows use separate
tasks.mdor external PM tools—weigh the cost of sync against this skill's tight coupling tospec.md. - Workflow fit: If your agent already adheres to strict RED-GREEN-REFACTOR phases, this skill's automatic transition announcements align well.
Why it is worth tracking
This skill addresses a real pain point: keeping task plans synchronized with evolving specifications. Its community momentum (60 stars, active author) suggests it's being used in production. Evaluate it when you're building agent loops that require disciplined planning without scope creep. For a deeper look, see its listing on OpenAgentSkill. Keep an eye on how the author handles edge cases like conflicting IDs—that's where the quality will show.
