gemini-mem-v3: Instructions file for Gemini CLI

GEMINI.md

gemini-mem-v3 GEMINI.md is an instructions file for Gemini CLI from JHdehao/gemini-mem-v3. It costs 99 tokens per session, scanned A, a copy of gemini-mem GEMINI.md, MIT.

Instructions for Gemini CLI, Google's command-line coding agent, to use project-level memory. The memory stores technical context, decisions, constraints, and active tasks.

In plain words
What is it for?
Use it to manage persistent coding context, retrieve stored memories, check memory health, and keep secrets out of saved memory.
Why use it?
It helps the agent retain relevant project context between completed conversations instead of starting from scratch.

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

gemini-mem-v3 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 8d 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

100% identical to gemini-mem GEMINI.md — 0 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.md

Use this extension as persistent memory for project-level coding context.

Memory behavior

  • Memory cards are generated from completed agent turns.
  • Retrieval combines local FTS shortlist and Gemini reranking.
  • Injected context is concise and biasing toward decisions, constraints, and active tasks.

Operator notes

  • Keep memory cards technical and concrete.
  • Avoid storing secrets; redaction is enforced before persistence.
  • Use npm run mem:status to inspect health quickly.
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.
