memmy-memory

memmy-memory is a skill for Claude Code, Codex from MemTensor/memmy-agent. It costs 50 tokens per session (674 once invoked), scanned A, original, MIT.

Instructions for using the memmy-memory command-line tool, which connects an agent to a persistent Memory service.

In plain words
What is it for?
Use it to open or close sessions, start or finish turns, search or read memories, add or delete memories, check service health, and make uncommon requests.
Why use it?
It helps an agent save and retrieve information across sessions instead of relying only on the current conversation.

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

memmy-memory 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.

Memmy Memory CLI

Use this skill when the task needs persistent agent memory through the memmy-memory command.

Command Selection

  • Check availability: read health.
  • Create or resume a session: read session open.
  • Close a session: read session close.
  • Begin a turn and retrieve prompt context: read turn start.
  • Finish a turn and write memory: read turn complete.
  • Search memory: read search.
  • Add a memory manually: read add.
  • Read one memory by id: read get.
  • Delete one memory by id: read delete.
  • Call uncommon HTTP routes for debugging: read raw.

Common Options

  • --url <url> sends requests to a specific Memory HTTP service.
  • --token <token> sends a bearer token.
  • --config <path> loads a specific Memmy config file.
  • --source <agent-source> identifies the calling agent/source, such as codex, cursor, or openclaw; use it on memory commands from installed agent skills.
  • --body '<json>', --json '<json-or-path>', and --body-file <path> provide request body fields.

Prefer explicit CLI parameters for required fields. Use JSON body options only for extra request fields or raw debugging.

Agent Workflow

  1. Use memmy-memory health before relying on Memory if service state is unknown.
  2. Use memmy-memory session open --source <agent-source> when a conversation or task begins.
  3. Use memmy-memory turn start --source <agent-source> before answering when prior memory may help.
  4. Use memmy-memory search --source <agent-source> for direct memory lookup outside a turn lifecycle.
  5. Use memmy-memory turn complete --source <agent-source> after the final answer to persist the interaction.
  6. Use memmy-memory add --source <agent-source> only for explicit facts, preferences, decisions, or durable project notes.

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.
