obsidian-agent-memory AGENTS.md

obsidian-agent-memory AGENTS.md is an instructions file for Codex, OpenCode from mithunyc/obsidian-agent-memory. It costs 195 tokens per session, scanned A, original, MIT.

A set of rules for an AI coding agent working with an Obsidian vault, a folder of linked Markdown notes. It defines how to read the vault’s rules, retrieve information, and close a work session.

In plain words
What is it for?
It guides information retrieval, restricts file creation and edits, applies the vault’s property schema, logs major changes, and runs a session closeout process.
Why use it?
It reduces accidental changes to settings or raw source files and keeps the agent’s work consistent with the vault’s structure.

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

obsidian-agent-memory 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 4d 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

Agent Memory System

Read the canonical rules file before taking any action in this vault.

00_System/AI/VAULT_RULES.md

Then follow the retrieval protocol to load only what you need:

00_System/AI/RETRIEVAL_PROTOCOL.md

At the end of every session, run the closeout protocol:

00_System/AI/SESSION_CLOSEOUT_PROTOCOL.md

Constraints

  • Do not modify .obsidian/ unless explicitly asked.
  • Treat any raw/ folder as immutable — read only.
  • Create only .md and .base files.
  • Use the property schema defined in 00_System/Templates/.
  • Log significant vault changes in 00_System/Logs/Vault-Changes.md.
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.
