What is ra-h_os CLAUDE.md?

A developer guide for ra-os, a local application that stores connected knowledge as a searchable graph. It covers the Next.js and TypeScript app, its SQLite database, and its MCP connection for AI assistants.

Use it when developing ra-os, working on its knowledge graph, database, MCP tools, API routes, or local setup.

It shows how to run the project locally and where its database, tools, settings, and documentation live. This gives an agent the project context needed to make changes safely.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00278	$0.00278
Opus 5.5	$0.00111	$0.00111
Sonnet 5.5	$0.00056	$0.00056
Haiku 4.5	$0.00028	$0.00028

Security

Grade A, and why

ra-h_os 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 2mo 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.

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.
