symbiote-init

symbiote-init is a skill for Claude Code, Codex from MohmmedAshraf/symbiote. It costs 87 tokens per session (1,885 once invoked), scanned A, original, MIT.

A setup skill that scans a project and records its structure, coding preferences, constraints, and architectural decisions.

In plain words
What is it for?
It is for initializing Symbiote, creating a project overview, scanning related projects for developer preferences, and storing the resulting context.
Why use it?
It gives AI tools a shared starting point for understanding an unfamiliar codebase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

symbiote-init scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Symbiote Project Init

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

MCP server is already registered globally by symbiote install. 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 symbiote-cli scan

Then start the server:

npx 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

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

symbiote-init is a skill published in the GitHub repository MohmmedAshraf/symbiote (6 stars, last pushed 7mo ago), licensed MIT. It adds 87 tokens to every session and 1,885 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
