obsidian-agent-memory: Instructions file for Gemini CLI

GEMINI.md

obsidian-agent-memory GEMINI.md is an instructions file for Gemini CLI from mithunyc/obsidian-agent-memory. It costs 150 tokens per session, scanned A, a copy of obsidian-agent-memory AGENTS.md, MIT.

A set of instructions for an AI agent working in an Obsidian vault, a folder of linked notes used as a personal knowledge base. It requires reading the vault's central rules and retrieval instructions before taking action.

In plain words
What is it for?
It helps retrieve information, create approved Markdown or database files, follow the vault's property format, and record significant updates.
Why use it?
It protects system settings and raw source notes from unintended changes and keeps edits consistent with the vault's templates. It also requires important changes to be recorded in a change log.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md.

This is mithunyc/obsidian-agent-memory's own configuration. It tells Gemini CLI how to work on obsidian-agent-memory itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything obsidian-agent-memory configures →

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 GEMINI.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.

Origin

This is a copy

84% identical to obsidian-agent-memory AGENTS.md — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Gemini — Vault Adapter

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

→ 00_System/AI/VAULT_RULES.md

Then follow the retrieval protocol:

→ 00_System/AI/RETRIEVAL_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.
