speckit-tasksGenerate an actionable, dependency-ordered tasks.md for the feature based on available design artifacts.
Speckit Tasks is an agent skill from kunstmusik/blue. Generate an actionable, dependency-ordered tasks.md for the feature based on available design artifacts.
Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires spec-kit project structure with .specify/ directory
It sits in Development, covering Spec-driven development. The repository describes itself as: Blue - An Integrated Music Environment. The licence is GPL-3.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 3c32d58. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires spec-kit project structure with .specify/ directory
From compatibility in the SKILL.md frontmatter.
Speckit Tasks loads about 3k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 1,481 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

FEATURE_DIR and TASKS_TEMPLATE must be absolute paths when provided. AVAILABLE_DOCS is a list of document names/relative paths available under FEATURE_DIR (for example research.md or contracts/). For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'''m Groot' (or double-quote if possible: "I'm Groot").

Context for task generation: $ARGUMENTS
The tasks.md should be immediately executable - each task must be specific enough that an LLM can complete it without additional context.
CRITICAL: Tasks MUST be organized by user story to enable independent implementation and testing.
Verification is constitution-driven: Generate automated regression, serialization, contract, runtime, UI, project-history commit→undo→redo, and quickstart tasks whenever the constitution or plan requires them. For unrelated behavior with no constitutional verification obligation, additional TDD tasks remain optional.
Every task MUST strictly follow this format:
- [ ] [TaskID] [P?] [Story?] Description with file pathFormat Components:
- [ ] (markdown checkbox)Examples:
- [ ] T001 Create project structure per implementation plan- [ ] T005 [P] Implement authentication middleware in src/middleware/auth.py- [ ] T012 [P] [US1] Create User model in src/models/user.py- [ ] T014 [US1] Implement UserService in src/services/user_service.py- [ ] Create User model (missing ID and Story label)T001 [US1] Create model (missing checkbox)- [ ] [US1] Create User model (missing Task ID)- [ ] T001 [US1] Create model (missing file path)From User Stories (spec.md) - PRIMARY ORGANIZATION:

Generate an actionable, dependency-ordered tasks.md for the feature based on available design artifacts. Speckit Tasks is an agent skill from kunstmusik/blue.md for the feature based on available design artifacts.
Speckit Tasks fits situations like: tasks that involve Spec-driven development.
Run `npx skills add kunstmusik/blue --skill speckit-tasks -a claude-code`. Or copy the skill folder (.agents/skills/speckit-tasks in kunstmusik/blue) into .claude/skills/speckit-tasks in your project. Claude Code loads it when a task matches its description.
Run `npx skills add kunstmusik/blue --skill speckit-tasks -a codex`. Or copy the skill folder (.agents/skills/speckit-tasks in kunstmusik/blue) into .agents/skills/speckit-tasks in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add kunstmusik/blue --skill speckit-tasks -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/speckit-tasks, .gemini/skills/speckit-tasks, .github/skills/speckit-tasks and .opencode/skills/speckit-tasks in your project.
SKILL.md names no scripts, command-line tools or credentials: Speckit Tasks is instructions for the agent only. Compatibility (from SKILL.md): Requires spec-kit project structure with .specify/ directory.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Speckit Tasks is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 3k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
