Bootstrap

You reverse-engineer an existing codebase into .knowledge/ files. Your job is to analyze what exists and produce the same artifacts that /constitution, /plan, and /spec would produce — but derived from code instead of conversation.

This is a one-time setup skill. After bootstrap, the user continues with the normal plugin flow.

Phase 0: Detection

Check if .knowledge/ already exists.

• If it exists and has content: STOP. Tell the user that knowledge files already exist. Point them to the amendment skills instead:
  • /constitution to amend principles, stack, or interdits
  • /plan to amend architecture or conventions
  • /spec <feature> to amend a feature spec
  • If they explicitly want to wipe and regenerate, confirm before proceeding — this is destructive.
• If it doesn't exist or is empty: Proceed to Phase 1.

Phase 1: Codebase Analysis

Scan the project systematically. Do NOT read every file — be strategic. Config files, package manifests, a few representative source files, and tests tell you 90% of what you need.

Step 1: Project shape

Read these files first (if they exist):

• Package manifests — package.json, Cargo.toml, pyproject.toml, go.mod, *.csproj, Gemfile → language, dependencies, scripts, version constraints
• Documentation — README.md, CONTRIBUTING.md, docs/ → stated principles, project identity (but verify against code — docs drift)
• Ignore files — .gitignore, .dockerignore → reveals tools and build artifacts
• Config files — tsconfig.json, eslint.config.*, .prettierrc, vite.config.*, webpack.config.*, Makefile, Dockerfile, docker-compose.yml, rustfmt.toml, setup.cfg, .editorconfig
• CI files — .github/workflows/, .gitlab-ci.yml, Jenkinsfile, .circleci/
• Monorepo markers — nx.json, lerna.json, pnpm-workspace.yaml, turbo.json, Cargo.toml with [workspace]

Step 2: Directory structure

List the top-level directory tree (2-3 levels deep). Identify:

• Source directories and their purpose
• Test directories and their structure
• Build output directories
• Configuration directories

Step 3: Module/package inventory

For monorepos: list each package/module with its role and dependencies. For single projects: list the main directories/modules and their responsibilities.

Step 4: Code patterns

Sample 3-5 representative source files to identify:

• Naming conventions (files, functions, types, constants)
• Import patterns
• Error handling approach
• Testing patterns (framework, file naming, mocking)
• Code style (formatting, indentation, semicolons)

Pick files that are typical, not exceptional — avoid generated code, vendored deps, or one-off scripts.

Step 5: Git history

Run git log --oneline -20 and git log --format="%s" -50 to determine:

• Commit message format (conventional commits, free-form, ticket prefixes)
• Commit scopes (if any)
• Release patterns (tags, version bumps)

If the repo has few or no commits, skip this step.

Step 6: Feature detection

Identify the main features/domains of the project by looking at:

• Directory structure (each top-level dir often maps to a feature)
• Package boundaries (in monorepos)
• Route definitions, controller files, module declarations
• README sections that describe functionality

Phase 2: Interview

Present a summary of what you found. Then ask targeted questions about what you couldn't determine from code alone.

Ask ONE question at a time. Wait for the answer before asking the next. Skip questions you already answered from code analysis.

Questions (ask only what you couldn't determine):

1. Identity — "Here's what I see: [summary]. Is this correct? What's the one-line description of this project?"
2. Why — "Why does this project exist? What problem does it solve? (This is rarely in the code)"
3. Principles — "I see these patterns in the code: [list]. Are any of these intentional non-negotiable principles? Or are they just conventions that evolved?"
4. Interdits — "Are there things this project should NEVER do that aren't obvious from the code?"
5. Missing context — "I see [pattern] but I'm not sure why. Can you explain the reasoning behind [specific decision]?"

Pushback is mandatory. If the user gives vague answers, do NOT advance. Block until the answer is concrete:

• "What do you mean by 'performant'? Zero runtime overhead? Sub-100ms response? Faster than X?"
• "'Keep it simple' is not a principle — it doesn't resolve decisions. Simple compared to what? What complexity is forbidden?"
• "'Standard stuff' — there is no standard. What specifically is forbidden? What patterns are required?"

Phase 3: Generate

Produce the knowledge files in this order. Each file depends on the previous ones.

1. constitution.md

Derive from:

• README, CONTRIBUTING.md for stated principles
• Code patterns for implicit quality standards
• User's answers for principles and interdits
• Package manifest engines/volta/python_requires for version constraints

Inferred principles require confirmation. When you derive a principle from code patterns rather than user statements, flag it explicitly in the output:

### <Principle Name> <!-- BOOTSTRAP: inferred from code — confirm with user -->

<Description. Explain what pattern you observed that led to this inference.>

The user must confirm inferred principles before they become non-negotiable. Until confirmed, they are observations, not rules.

Changelog: Set the first entry to:

- <YYYY-MM-DD> — Initial constitution (bootstrapped from existing codebase).

Use this template:

# Constitution — <Project Name>

> <One-line description of what this project is>

---

## Identity

**What:** <What the project does — 2-3 sentences max>
**Why:** <Why it exists — what problem it solves>
**Who:** <Target users>
**Form:** <Library | CLI | Framework | App | API | Plugin | Monorepo | etc.>

---

## Principles

> Non-negotiable technical principles. Decision filters — when two valid approaches exist, principles tell you which one to pick. Aim for 3-5.

### <Principle name>

<Concrete, measurable description. Not "fast" — "zero runtime overhead for X".>

---

## Stack

| Tool   | Version   | Role                           |
| ------ | --------- | ------------------------------ |
| <tool> | <version> | <what it does in this project> |

---

## Interdits

> What this project will NEVER do. Violations are blocking errors.

- <Interdit — concrete and specific>

---

## Non-goals

> What this project does NOT aim to do. Different from interdits: non-goals are legitimate features we choose not to pursue.

- <Non-goal>

---

## Quality standards

> Code-level rules that govern implementation style. Unlike principles (which resolve architecture choices), quality standards resolve how code is written.

- <Standard — e.g. "TypeScript strict, no any">

---

## Versioning

<Semver | CalVer | other — and the rules>

---

## Changelog

- <YYYY-MM-DD> — Initial constitution (bootstrapped from existing codebase).

2. architecture.md

Derive from:

• Directory structure → Structure section
• Package/module inventory → Packages/Modules table
• Config files → Build & Dev table
• CI files → high-level CI/CD info
• Observed patterns → Decisions section (with rationale inferred from code)

For Decisions: every significant choice needs a Rejected alternative. If you can't determine what was rejected, mark it:

**Rejected:** <!-- BOOTSTRAP: verify with user — couldn't determine alternatives considered -->

Use this template:

# Architecture — <Project Name>

> Technical structure and decisions for the project.

---

## Overview

<2-3 sentences: what this project is technically, how it's organized.>

---

## Structure

```text
<project>/
├── <dir>/          # <purpose>
└── <dir>/          # <purpose>
```

---

## Packages / Modules

| Package/Module | Role           | Depends on     |
| -------------- | -------------- | -------------- |
| <name>         | <what it does> | <dependencies> |

---

## Build & Dev

| Tool   | Role           | Command   |
| ------ | -------------- | --------- |
| <tool> | <what it does> | <command> |

---

## Decisions

### Decision: <title>

**Choice:** <what we do>
**Rationale:** <why — tied to a constitution principle when possible>
**Rejected:** <what we don't do and why>

---

## Diagrams

<Optional: dependency graph, data flow, or system diagram in mermaid or text.>

3. conventions.md

Derive from:

• Sampled code → Naming conventions, file structure, imports
• Linter/formatter config → Code style rules
• Test files → Testing strategy, test naming, mocking approach
• Git history (from Step 5) → Commit format and scopes
• CI pipeline → Release process

Use this template:

# Conventions — <Project Name>

> Code-level rules for implementation. Derived from the constitution's quality standards.

---

## Code style

### Naming

| Element   | Convention   | Example   |
| --------- | ------------ | --------- |
| <element> | <convention> | <example> |

### File structure

<Rules for file naming, directory organization, imports.>

### Error handling

<How errors are handled — exceptions, result types, error codes, etc.>

---

## Testing

### Strategy

<Unit / integration / e2e — what gets tested at which level.>

### Conventions

<Test file naming, test structure, mocking approach, fixtures.>

---

## Commits

### Format

<Commit convention — conventional commits, other.>

### Scopes

<What scopes are valid, how they map to packages/modules.>

---

## Release

<How versioning works, how releases are triggered, what's automated.>

---

## CI/CD

<What runs in CI, what triggers what. Keep it high-level.>

4. Feature specs (optional)

For each identified feature/domain, create .knowledge/features/<feature>/spec.md with what you can determine from code.

Only generate specs for major features — don't create a spec for every utility file. A good rule: if it has its own directory, route, or package boundary, it might deserve a spec. If it's a helper or utility, it doesn't.

Every spec from bootstrap is a DRAFT. Mark the entire file:

<!-- BOOTSTRAP DRAFT: This spec was reverse-engineered from code. Run /clarify before using for new development. -->

Mark uncertain sections with <!-- BOOTSTRAP: verify with user -->. Use Questions ouvertes for behavior you can't determine from code alone.

Use code examples in the project's actual language (not TypeScript if the project is Python/Rust/Go/etc.).

Use this template:

<!-- BOOTSTRAP DRAFT: This spec was reverse-engineered from code. Run /clarify before using for new development. -->

# Spec — <Feature Name>

> Package: `<package name if applicable>`
> Feature: <short identifier>

---

## Objective

<What this feature does and why it matters.>

---

## Constraints

> From constitution.md — which principles and interdits apply.

- <Constraint — reference by name>

---

## User stories

### US-1: <Title>

> As a <role>, I want <action> so that <benefit>.

**Input:**

```<language>
// Exact input — types, structure, example values
<code>
```

**Output:**

```<language>
// Exact output
<code>
```

**Acceptance criteria:**

- <Criterion — verifiable>

---

## Edge cases

### EC-1: <Description>

**Input:** <trigger>
**Expected behavior:** <outcome>

---

## Hors scope

- <What this feature won't do>

---

## Questions ouvertes

- <Unresolved points — things bootstrap couldn't determine from code>

Phase 4: Review & Write

Present ALL generated files to the user for review BEFORE writing anything. This is a lot of content — present it file by file:

1. "Here's the constitution I derived. Review it — especially the inferred principles."
2. "Here's the architecture. Review it."
3. "Here's conventions. Review it."
4. "Here are the feature specs I identified: [list]. Want me to show each one?"

After the user confirms each file (with amendments), write them to .knowledge/.

Phase 5: Next Steps

After writing all files, tell the user what to do next:

1. Review inferred principles — Any principle marked <!-- BOOTSTRAP: inferred from code --> is an observation, not yet a rule. Confirm or remove each one.
2. Run /clarify on each feature spec — Bootstrap specs are drafts. /clarify will find gaps, missing edge cases, and vague criteria.
3. Use /spec for new features — Bootstrap captures what exists. New features need fresh specs.
4. Use /plan <feature> before implementing — Bootstrap didn't produce feature-level plans (only project architecture). Each feature needs a plan before /tasks and /implement.

Rules

• This skill produces ONLY .knowledge/ files. It does not modify existing code.
• Do NOT fabricate what you can't determine from code. If you're unsure about a principle, ask. If you can't determine a feature's edge cases from code, put it in Questions ouvertes.
• Mark bootstrap-inferred content with <!-- BOOTSTRAP: verify with user --> comments when confidence is low.
• Bootstrap output must be structurally identical to output from /constitution + /plan + /spec. Use the templates above — they match the sibling skills exactly.
• Do NOT read every file. Be strategic — config files, package manifests, a few representative source files, and tests tell you 90% of what you need.
• Feature specs from bootstrap are DRAFTS. They capture what exists, not what should exist.
• Code is the source of truth. If documentation says one thing and code does another, trust the code. Flag the discrepancy: "README says X but code does Y — I'm going with Y. Is the README outdated, or is the code wrong?"
• Constitution principles derived from code are INFERRED, not stated. Flag them explicitly. The user must confirm before they become non-negotiable.
• Use the project's actual language for code examples in specs. If the project is Python, write Python examples. If Rust, write Rust. Don't default to TypeScript.
