What is ObsidianArc CLAUDE.md?

A repository instruction file for ObsidianArc, a self-hosted AI platform with a Go server, provider routing, usage tracking, an admin console, chat, and agent work modes. It directs agents to follow the repository's AGENTS.md file for conventions.

Use it as project context when an agent works on the ObsidianArc codebase.

It points agents to one shared source of project rules, reducing the risk of inconsistent instructions.

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	$0.00065	$0.00065
Opus 5.5	$0.00026	$0.00026
Sonnet 5.5	$0.00013	$0.00013
Haiku 4.5	$0.00006	$0.00006

Security

Grade A, and why

ObsidianArc 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 yesterday.

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.

What it actually says

@AGENTS.md

The conventions for this repository live in AGENTS.md, as one file that every agent working here reads. Keeping a second copy is how two agents end up following two different rules, which is the exact failure this file exists to prevent — so add to AGENTS.md rather than here.

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.
