db-mcp: Instructions file for Claude Code

CLAUDE.md

db-mcp CLAUDE.md is an instructions file for Claude Code from erayguner/db-mcp. It costs 1,672 tokens per session, scanned A, a copy of ruv-FANN CLAUDE.md, MIT.

A set of instructions for using Claude Code in the db-mcp project. It describes project rules, folder locations, architecture choices, and configuration for RuFlo V3, a coding-agent workflow tool.

In plain words
What is it for?
It guides work on source code, tests, documentation, configuration, scripts, validation, and state-changing features in the db-mcp repository.
Why use it?
It gives the coding agent project-specific boundaries, such as where files belong, when to create files, and which development practices to follow.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: names the TodoWrite tool; positional $N argument; mentions Claude Code.

This is erayguner/db-mcp's own configuration. It tells Claude Code how to work on db-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything db-mcp configures →

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

db-mcp CLAUDE.md scanned grade A with 0 findings 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 7d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

98% identical to ruv-FANN CLAUDE.md — 39 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Claude Code Configuration - RuFlo V3

Behavioral Rules (Always Enforced)

  • Do what has been asked; nothing more, nothing less
  • NEVER create files unless they're absolutely necessary for achieving your goal
  • ALWAYS prefer editing an existing file to creating a new one
  • NEVER proactively create documentation files (*.md) or README files unless explicitly requested
  • NEVER save working files, text/mds, or tests to the root folder
  • Never continuously check status after spawning a swarm — wait for results
  • ALWAYS read a file before editing it
  • NEVER commit secrets, credentials, or .env files

File Organization

  • NEVER save to root folder — use the directories below
  • Use /src for source code files
  • Use /tests for test files
  • Use /docs for documentation and markdown files
  • Use /config for configuration files
  • Use /scripts for utility scripts
  • Use /examples for example code

Project Architecture

  • Follow Domain-Driven Design with bounded contexts
  • Keep files under 500 lines
  • Use typed interfaces for all public APIs
  • Prefer TDD London School (mock-first) for new code
  • Use event sourcing for state changes
  • Ensure input validation at system boundaries

Project Config

  • Topology: hierarchical-mesh
  • Max Agents: 15
  • Memory: hybrid
  • HNSW: Enabled
  • Neural: Enabled

Build & Test

# Build
npm run build

# Test
npm test

# Lint
npm run lint
  • ALWAYS run tests after making code changes
  • ALWAYS verify build succeeds before committing

Security Rules

  • NEVER hardcode API keys, secrets, or credentials in source files
  • NEVER commit .env files or any file containing secrets
  • Always validate user input at system boundaries
  • Always sanitize file paths to prevent directory traversal
  • Run npx @claude-flow/cli@latest security scan after security-related changes
  • All operations MUST be concurrent/parallel in a single message
  • Use Claude Code's Task tool for spawning agents, not just MCP
  • ALWAYS batch ALL todos in ONE TodoWrite call (5-10+ minimum)
  • ALWAYS spawn ALL agents in ONE message with full instructions via Task tool
  • ALWAYS batch ALL file reads/writes/edits in ONE message
  • ALWAYS batch ALL Bash commands in ONE message

Changes

What this file has done since we first saw it

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.
