autospec-checklistGenerate YAML checklist for feature quality validation. An agent skill from ariel-frischer/autospec.
Autospec Checklist is an agent skill from ariel-frischer/autospec. Generate YAML checklist for feature quality validation.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Unit testing. The repository describes itself as: CLI for streamlined spec-driven development. The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 3381f26. 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 (its code samples are yaml and bash).
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.
Autospec Checklist loads about 2.4k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 728 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.
The full file from ariel-frischer/autospec at commit 3381f26, republished under its MIT licence (© ariel-frischer). 728 words, ~2,353 tokens.
.claude/skills/autospec-checklist/SKILL.md (or your agent's skills folder).This Agent Skill is generated from autospec.checklist. When the user invokes "$autospec-checklist" or "/autospec.checklist", load and follow these instructions directly. Treat the text after the skill or command name as "$ARGUMENTS". Do not route back through "autospec checklist"; this skill is the prompt for the stage.

CRITICAL CONCEPT: Checklists are UNIT TESTS FOR REQUIREMENTS WRITING - they validate the quality, clarity, and completeness of requirements in a given domain.
NOT for verification/testing:
FOR requirements quality validation:
Metaphor: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.
$ARGUMENTSYou MUST consider the user input before proceeding (if not empty).
The following paths have been pre-computed and are available for use:
{{.FeatureDir}}{{.FeatureSpec}}Clarify intent (dynamic): Derive up to THREE initial contextual clarifying questions. They MUST:

Autospec Checklist fits situations like: tasks that involve Unit testing.
Run `npx skills add ariel-frischer/autospec --skill autospec-checklist -a claude-code`. Or copy the skill folder (.agents/skills/autospec-checklist in ariel-frischer/autospec) into .claude/skills/autospec-checklist in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ariel-frischer/autospec --skill autospec-checklist -a codex`. Or copy the skill folder (.agents/skills/autospec-checklist in ariel-frischer/autospec) into .agents/skills/autospec-checklist 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 ariel-frischer/autospec --skill autospec-checklist -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/autospec-checklist, .gemini/skills/autospec-checklist, .github/skills/autospec-checklist and .opencode/skills/autospec-checklist in your project.
SKILL.md names no scripts, command-line tools or credentials: Autospec Checklist is instructions for the agent only.
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.
Autospec Checklist is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
