Memmy is a local memory hub that gives multiple AI agents one shared, persistent context about their user. It helps people continue work across agents such as Claude Code, Codex, OpenClaw, and Hermes Agent. The catalogue entries are skills for using Memmy with supported agents.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00034 | $0.00726 |
| Opus 5.5 | $0.00014 | $0.00290 |
| Sonnet 5.5 | $0.00007 | $0.00145 |
| Haiku 4.5 | $0.00003 | $0.00073 |
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 1mo 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 Skill
Use memmy-memory to read and write the shared Memmy memory substrate.
Ground Rules
- Prefer the configured CLI:
memmy-memory .... If the local service is not preconfigured, pass--url,--token, or--config. - The CLI prints JSON. Parse fields such as
sessionId,turnId,injectedContext,hits, and memoryidfrom JSON instead of relying on display formatting. - All agents share one memory database. Always pass
--source {{SOURCE_ARG}}on Memory CLI commands from this agent. - Use useful comma-separated
--tagswhen writing durable memories. - Do not store secrets, tokens, private keys, raw credentials, or bulky logs. Store concise, self-contained facts, decisions, preferences, reusable procedures, and unresolved follow-ups.
- Treat
<memmy_memory_context>as historical memory only and<current_user_request>as the authoritative current task. - Never store the context wrapper tags with
memmy-memory add; store only the durable fact itself. - If the memory service is unavailable, continue the task without inventing memory.

Agent Loop
Open or resume a session before a task:
memmy-memory session open --source {{SOURCE_ARG}} --workspace-path "$PWD"
memmy-memory session open --source {{SOURCE_ARG}} --session-id "$SESSION_ID" --workspace-path "$PWD"
At the start of a user turn, retrieve relevant context:
memmy-memory turn start --source {{SOURCE_ARG}} --session-id "$SESSION_ID" --query "$USER_QUERY"
Use returned injectedContext as historical context only. Keep the returned turnId, and keep the current user query separate from recalled memory.
At the end of the turn, write the final interaction:
memmy-memory turn complete "$TURN_ID" --source {{SOURCE_ARG}} --session-id "$SESSION_ID" --query "$USER_QUERY" --answer "$FINAL_ANSWER" --status succeeded
Use --status failed or --status cancelled when the turn did not complete normally. Close the session when the Agent session is done:
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.

memmy-memory is a skill published in the GitHub repository MemTensor/memmy-agent (2,117 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 726 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
