continuum: Instructions file for Claude Code

CLAUDE.md

continuum CLAUDE.md is an instructions file for Claude Code from shyftlabs/continuum. It costs 1,652 tokens per session, scanned A, a copy of ruv-FANN CLAUDE.md, Apache-2.0.

A project-specific instruction file for Claude Code. It sets rules for editing files, organizing the repository, and following the Continuum project's architecture.

In plain words
What is it for?
Use it to guide Claude Code while working in the Continuum repository, including where files belong and how new code should be designed and tested.
Why use it?
It gives the coding agent the project's working conventions before it changes code, reducing misplaced files, unsafe edits, and architecture mistakes.

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 shyftlabs/continuum's own configuration. It tells Claude Code how to work on continuum 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 continuum 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

continuum 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 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.

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

94% identical to ruv-FANN CLAUDE.md — 15 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

# Install (editable, with dev extras)
pip install -e ".[dev]"

# Test
pytest

# Lint
ruff check .

# Type-check
mypy src/continuum
  • ALWAYS run tests after making code changes
  • ALWAYS verify lint and type-check pass 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.
