code: Skill for Claude Code

.specify/extensions/superspec/.specify-dev/agent-commands/claude/speckit-superspec-tasks/SKILL.md

speckit-superspec-tasks is a skill for Claude Code, Codex from HelixDevelopment/code. It costs 24 tokens per session (545 once invoked), scanned A, original, MIT.

A command that turns a feature specification into a phased task list, with dependencies and markers for parallel work, tests, reviews, and delegation.

In plain words
What is it for?
Use it to create a tasks.md file for a feature in a spec-driven project. It organizes work from setup through implementation and final polish.
Why use it?
It removes the manual work of breaking a large feature plan into ordered, actionable tasks. It also makes required checkpoints and task dependencies explicit.

This is HelixDevelopment/code's own configuration. It tells Claude Code and Codex how to work on code itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything code configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

speckit-superspec-tasks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

speckit.superspec.tasks

Generate a phased task breakdown using writing-plans skills.

Usage

/speckit.superspec.tasks [spec-number|spec-path]

Process

  1. Read the spec, plan, and constitution for the target feature
  2. Read the template at .specify/templates/tasks-template.md
  3. Superpowers detection: Check for writing-plans skill
    • If found: Read the writing-plans SKILL.md and follow its task decomposition process, adapting outputs to the tasks template structure
    • If not found: Decompose directly from the plan using the template
  4. Organize tasks by phase: Setup → Foundational → User Stories (by priority) → Polish
  5. Apply execution markers to each task:
    • [P] — can run in parallel (different files, no dependencies)
    • [TDD] — must follow RED-GREEN-REFACTOR discipline
    • [REVIEW] — requires code review before proceeding
    • [SUBAGENT] — can be delegated to a subagent
  6. Define phase dependencies and checkpoint gates
  7. Write to specs/NNN-feature-name/tasks.md

Output

specs/NNN-feature-name/tasks.md with phased task breakdown.

Execution Markers

Marker Meaning Behavior
[P] Parallel Can run concurrently with other [P] tasks
[TDD] Test-Driven Must follow RED-GREEN-REFACTOR: write test → fail → implement → pass
[REVIEW] Review Gate Pause for human code review before proceeding
[SUBAGENT] Subagent Can be dispatched to a parallel subagent

Superpowers Adaptation

When using the writing-plans skill, adapt its outputs:

  • Implementation blueprints → merge into specs/NNN/tasks.md using template structure
  • Task dependencies → map to the Dependencies section
  • Parallel opportunities → mark with [P] and [SUBAGENT]

See .specify/extensions/superspec/references/superpowers-bridge.md for full adaptation rules.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

speckit-superspec-tasks is a skill published in the GitHub repository HelixDevelopment/code (2 stars, last pushed 3d ago), licensed MIT. It adds 24 tokens to every session and 545 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
