rag-vault AGENTS.md

rag-vault AGENTS.md is an instructions file for Codex, OpenCode from maxrotemberg04-spec/rag-vault. It costs 260 tokens per session, scanned A, original, MIT.

Project instructions for a local search system that finds relevant notes in an Obsidian vault, a personal note-taking database, and returns answers with links to the source notes.

In plain words
What is it for?
Use them when working on rag-vault to search notes, run its tests, protect private vault data, and keep changes small and reviewable.
Why use it?
They keep answers grounded in the vault’s contents and set rules for testing, secrets, commits, explanations, and reviews.

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

rag-vault AGENTS.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 5d 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.

What it actually says

rag-vault — agent instructions

Local-first RAG over Max's Obsidian vault — ask the second brain questions in the terminal, get grounded answers with citations that deep-link back into Obsidian. Retrieval is hand-rolled (BM25 + embeddings + reciprocal rank fusion), and the engine doubles as an MCP server so local agents can search the notes as a tool.

Public portfolio repo — this code is part of Max's pitch; keep it interview-clean. Python 3.12. Tests: pytest -q (same as CI).

Hard rules

  1. Commits are 100% Max. Never add AI co-author trailers or AI attribution to commits, code comments, or docs.
  2. Evidence before "done" — run the tests and show the output.
  3. No secrets in git; .env stays local — and never commit real vault content; fixtures/demo notes only.
  4. Teach while doing — Max is learning; explain the why in plain terms as you work.
  5. Cross-model review before merge on non-trivial changes — whichever model wrote it, the other reviews.

Keep diffs small and readable — every line in this repo should be explainable in an interview.

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.
