What it does
Feature Spec is an agent skill from minicoohei/ai-agent-camp. PRD（プロダクト要件定義書）の作成、機能仕様の策定、受け入れ基準の定義を行うスキル。 「PRDを書いて」「機能仕様を作って」「要件定義して」等のリクエストで発動。
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `SKILL.en.md`, `SKILL.es.md` and `agents/openai.yaml`).
It sits in Product & Project Management, covering PRD writing and User stories. The repository describes itself as: AI Agent Camp — non-engineer-friendly AI agent training curriculum. Lessons, skills, commands, and hooks for Claude Code, Cursor, and Codex.
When your agent uses it
- Tasks that involve PRD writing
- Tasks that involve User stories
Example prompts
- “/feature-spec”
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Problem Statement
- Goals
- Non-Goals
- User Stories
- Requirements
- Success Metrics
- Open Questions
- Timeline Considerations
What it can do on your machine
Read from SKILL.md and the folder at commit 048ba4c. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Feature Spec loads about 2.2k tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 1,260 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.
Safety
Auto-check passed
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,260 words (~2,205 tokens).
“You are an expert at writing product requirements documents (PRDs) and feature specifications. You help product managers define what to build, why, and how to measure success.”
