# blueprint

Runs a plan-writing session: reads your codebase, asks clarifying questions in rounds, and leaves the plan itself to a separate skill.

## What it does

This skill opens a planning session. It parses your feature description, reads `references/templates.json`, and asks which plan template to use — one option per template plus an “Other” entry where you describe your own. The chosen template sets the structure and the level of detail the questions aim at.

Next the agent explores the project: layout, main modules, existing conventions, and the files your request touches. It reads actual source files rather than guessing. Then it asks 3–5 clarifying questions in the format from `references/questions.md`. Answers can come back as shorthand such as `1a, 2b, 3e`, as prose, or mixed. Each round it prints the refined prompt in a blockquote so you can watch your answers reshape the plan.

The questioning does not stop on its own. Rounds continue until you invoke the `blueprint-generate` skill, which ends the Q&A and produces the plan. Until then the skill writes no code and edits no files — it only gathers information. Once a template is picked, every message ends with the progress line `✓ Explore  ● Plan  ○ Write  ○ Refine`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add imbue-ai/blueprint --skill blueprint -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/blueprint/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/blueprint/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add imbue-ai/blueprint --skill blueprint -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/blueprint/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add imbue-ai/blueprint --skill blueprint -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/blueprint/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install imbue-ai/blueprint blueprint
```

2. **Manually: put the files in place**
- File: `.github/skills/blueprint/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add imbue-ai/blueprint --skill blueprint -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/imbue-ai/blueprint --path skills/blueprint
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/blueprint/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add imbue-ai/blueprint --skill blueprint -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/imbue-ai/blueprint/tree/HEAD/skills/blueprint/SKILL.md

## When to use it
- think through an implementation plan before touching code
- surface requirements you had not spelled out
- check a change against existing project patterns
- capture decisions in a running draft prompt
- break a vague feature idea into concrete points

## Example prompts
- Start a blueprint session for the new notification system
- Run blueprint and figure out how this project handles background jobs
- Use blueprint to plan the payment module refactor

## Blueprint — Start plan session

Start a new plan-writing session. Help the user write an implementation plan through multi-round Q&A.

### Step 1: Parse arguments and select template

Parse the user's message for the feature description.

Read [references/templates.json](references/templates.json) to get the available templates. Ask the user which template they'd like to use — one per template, using the template's `name` as the label and `description` as the description. Always include an "Other" option so the user can describe a custom template.

This is the ONLY time you should ask a template selection question during the session.

### Step 2: Read the plan template

Read the selected template's `prompt` field to understand the structure and level of detail expected. If the user selected "Other", use their custom description as the template prompt.

Your questions should match the template's level and perspective.

### Step 3: Explore the codebase

Explore the project to understand:
- The project structure, key modules, and architecture
- Existing patterns and conventions
- Files and systems relevant to the user's request

Spend real effort here. Read actual source files.

### Step 4: Ask clarifying questions

Help the user think through everything they'd need to answer in order to write that plan well.

Based on the codebase exploration, ask 3-5 clarifying questions following the format in [references/questions.md](references/questions.md).

Guidelines:
- Keep text between questions brief — a sentence or two of context at most, not a full analysis
- Gather facts before asking — if something can be determined by reading code, searching docs, or looking up external references, find the answer yourself. Do not make subjective decisions on behalf of the user
- Look up external documentation, APIs, or tools when relevant
- Ground questions in what you found in the codebase — do NOT ask questions whose answers are already obvious from the code
- Questions must match the level and perspective of the selected template — if the template asks about external behavior, ask about external behavior. If it asks about implementation details, ask about implementation details
- Users generally expect to continue existing patterns and expand their system — only question existing patterns when the user's change clearly conflicts with them. Focus on what's new or ambiguous
- Do NOT ask questions about the plan template itself — ask questions that help define what to build
- Do NOT ask about implementation details unless the plan template explicitly calls for them

Before the questions, add this hint:
