What is mnemo AGENTS.md?

Repository instructions for mnemo, a tool that indexes AI coding sessions from multiple assistants into one searchable SQLite database. They describe the project’s purpose, files, structure and agent guidance.

Use them when changing mnemo, especially to understand its Go project layout, key files and supported session-indexing components.

They give an agent the context needed to work in the repository without guessing where code or documentation belongs.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02470	$0.02470
Opus 5.5	$0.00988	$0.00988
Sonnet 5.5	$0.00494	$0.00494
Haiku 4.5	$0.00247	$0.00247

Security

Grade A, and why

mnemo 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.

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.
