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 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.

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.
