speckit-planExecute the implementation planning workflow using the plan template to generate design artifacts.
Speckit Plan is an agent skill from kunstmusik/blue. Execute the implementation planning workflow using the plan template to generate design artifacts.
Its SKILL.md is about 2.1k 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.
2 steps, taken from the step headings 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 Plan loads about 2.1k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 982 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.

Execute the implementation planning workflow using the plan template to generate design artifacts. Speckit Plan is an agent skill from kunstmusik/blue. Execute the implementation planning workflow using the plan template to generate design artifacts.
Speckit Plan fits situations like: tasks that involve Spec-driven development.
Run `npx skills add kunstmusik/blue --skill speckit-plan -a claude-code`. Or copy the skill folder (.agents/skills/speckit-plan in kunstmusik/blue) into .claude/skills/speckit-plan in your project. Claude Code loads it when a task matches its description.
Run `npx skills add kunstmusik/blue --skill speckit-plan -a codex`. Or copy the skill folder (.agents/skills/speckit-plan in kunstmusik/blue) into .agents/skills/speckit-plan 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-plan -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-plan, .gemini/skills/speckit-plan, .github/skills/speckit-plan and .opencode/skills/speckit-plan in your project.
SKILL.md names no scripts, command-line tools or credentials: Speckit Plan 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 Plan 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 2.1k tokens (SKILL.md is roughly 8.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
