loomem: Instructions file for Claude Code

CLAUDE.md

loomem CLAUDE.md is an instructions file for Claude Code from vvooki-sys/loomem. It costs 3,809 tokens per session, scanned A, original, Apache-2.0.

Project-specific instructions for Loomem, a single-user memory engine that stores context for AI agents and exposes memory tools.

In plain words
What is it for?
Use them when changing Loomem’s code, documentation, website content, or release files.
Why use it?
They tell AI coding assistants which rules apply to Rust, documentation, releases, and live project data, reducing accidental changes outside the task.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is vvooki-sys/loomem's own configuration. It tells Claude Code how to work on loomem 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 loomem 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

loomem 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — rules for AI code generators in the Loomem repo

Hard rules every AI assistant (Claude Code, Cowork, Copilot, Cursor, …) must follow when touching this repo. Some are enforced by CI; the rest are enforced in review. Deep rationale, complexity carve-outs and edge cases live in docs/agent-conventions.md — this file stays short on purpose, because it loads into context every session.

What Loomem is. An open-core, single-user memory engine (Apache-2.0, vvooki-sys/loomem), forked from Engram. The repo is public — assume external readers and their agents. Public positioning: "the open-source context layer for LLM agents." It is memory-only (the memory_* MCP tool set, no file layer) and single-user (no accounts, RBAC, SSO, multi-tenancy). Those two product boundaries are frozen (see § Product boundaries).

Router — read the subset that applies

  • Changing Rust code → § Five hard rules + § Build & run + § Repo map + § Rust rules.
  • Docs / landing / content / GEO → § Docs & site + hard rule 5 (surgical). A docs task never touches Rust.
  • Dashboard (loomem-dashboard/, React SPA) → § Build & run (dashboard bullet) + hard rule 5. A dashboard task touches no Rust beyond loomem-server/src/spa.rs.
  • Cutting a release → § Releases.
  • Always → § Five hard rules, especially live-state (rule 4), product boundaries (rule 3), secrets (rule 1).

Five hard rules (never break these)

  1. Secrets & personal data never get committed. No API keys, tokens, passwords, production endpoints — and no real names or private data in entities.toml / synonyms.toml (gitignored; only *.example variants are tracked). Any user content that gets persisted anywhere, including derived/audit fields like original_content, must pass through sanitizer + the PII filter — not just the visible content. .gitleaks.toml catches some leaks; you are the first gate. See something sensitive in a diff → stop and tell the user.

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.
