Symbiote Project Init

Initialize Symbiote for the current project — scan codebase and extract DNA + intent.

The plugin handles MCP registration and CLI auto-installation. This skill only scans and extracts.

Process

1. Scan the codebase and start the server
2. Write project overview
3. Scan ALL projects for developer identity
4. Build complete DNA entries, constraints, and decisions
5. Dispatch subagent with pre-built entries
6. Print one-line summary

Step 1: Scan and Start Server

Run these as SEPARATE bash commands:

npx -y symbiote-cli scan

Then start the server:

npx -y symbiote-cli serve --no-open > /dev/null 2>&1 &

Then wait and verify:

sleep 3 && curl -s http://127.0.0.1:$(cat .brain/port)/internal/health

IMPORTANT: Do NOT combine scan and serve into one command. The scan must finish and release the DB lock before the server starts.

Step 2: Write Project Overview

Write .brain/intent/overview.md — a concise project summary that gives AI tools instant context.

Read the codebase context (CLAUDE.md, package.json, top-level structure, scan results) and write a markdown file with this exact structure:

# {Project Name}

{One sentence: what this project does and who it's for.}

## Tech Stack

- {Language/runtime} ({key detail})
- {Framework} ({purpose})
- {Database/storage} ({why chosen})
- {Other significant deps}

## Architecture

- `{top-level-dir}/` — {what it contains}
- `{top-level-dir}/` — {what it contains}

## Key Patterns

- {How data flows}
- {How modules connect}

## Entry Points

- `{file}` — {what it does}

Rules: keep it under 40 lines, no frontmatter, be specific to THIS project.

Step 3: Scan ALL Projects for Developer Identity

Read the developer's full coding identity across every project:

1. ~/.claude/CLAUDE.md — global instructions
2. Every CLAUDE.md in ~/.claude/projects/*/ — all project instructions
3. Every .md file in ~/.claude/projects/*/memory/ — all memories
4. ./CLAUDE.md — current project

Read ALL of these. Do not skip any.

Also extract the developer's identity from the global CLAUDE.md:

• Name (look for "Name:", "Author:", or similar)
• Email
• GitHub handle
• Website/URL

Step 4: Build Complete DNA Entries

From everything in Step 3, build three COMPLETE lists. Every entry must be fully formed — do NOT leave fields empty.

DNA entries

Build each entry as a COMPLETE JSON object with ALL fields filled:

{
    "rule": "Use 4-space indentation everywhere, never tabs",
    "reason": "Consistency across polyglot stack eliminates context-switching friction and keeps diffs uniform",
    "category": "formatting",
    "applies_to": ["typescript", "javascript", "json", "php"],
    "not_for": ["go"],
    "source": "explicit"
}

EVERY field is required:

• rule — one specific sentence, self-contained
• reason — WHY this matters. NEVER leave empty. Generic "for consistency" is not acceptable.
• category — use organic categories: formatting, patterns, architecture, workflow, testing, tooling, ai-collaboration
• applies_to — list of languages/frameworks in lowercase. Empty [] means universal.
• not_for — exclusions where a rule doesn't apply. Omit if no exclusions.
• source — always "explicit" for init

Categories to cover (verify entries for each):

• formatting — indentation, quotes, semicolons, line length, file naming
• patterns — early returns, composition over inheritance, small functions, naming, error handling, type strictness
• architecture — project structure, separation of concerns, module boundaries
• workflow — commit style, push policy, destructive DB ops
• testing — framework per language, TDD, test structure
• tooling — framework choices per stack
• ai-collaboration — concise responses, research before changing

Confidence scoring:

• Found in 3+ project CLAUDE.md files → 1.0
• Found in 1-2 projects → 0.7
• Current project only → 0.5

Constraints (project rules)

For THIS project only. Use propose_constraint MCP tool.

Decisions (architectural choices)

For THIS project only. Use propose_decision MCP tool.

Step 5: Dispatch Subagent

Launch a single Agent to record everything. Pass the COMPLETE pre-built entries — do NOT ask the subagent to figure out fields.

Critical: also pass the developer identity so the subagent can update the profile metadata.

Agent prompt template:

Record the following Symbiote entries using MCP tools. Call tools in parallel where possible.

## Developer Identity

After recording all entries, the profile at ~/.symbiote/profiles/personal.json needs its metadata updated.
Read the file, update the "profile" block with:
- name: {developer name}
- handle: {github handle}
- bio: {one-liner about their coding identity, synthesized from the DNA entries}
Then write the file back.

## DNA entries

Use `record_instruction` for each. Pass the EXACT JSON shown — do not modify or simplify the fields.

1. {"rule": "...", "reason": "...", "category": "...", "applies_to": [...], "not_for": [...], "source": "explicit"}
2. ...

## Constraints

Use `propose_constraint` for each with `scope: "global"` and a slugified `id`:
1. [constraint]

## Decisions

Use `propose_decision` for each with `scope: "global"` and a slugified `id`:
1. [decision]

Return counts: { dna: N, constraints: N, decisions: N, failed: N }

Step 6: Output

One line, nothing more:

Symbiote initialized — scanned 350 files, recorded 48 DNA entries, 5 constraints, 3 decisions.

Do NOT render tables, lists, or per-entry details.
