synap

synap is a skill for Claude Code from maximem-ai/maximem_synap_sdk. It costs 0 tokens per session (3,343 once invoked), scanned A, original, Apache-2.0.

A managed memory layer for AI agents that stores structured facts, preferences, past events, and entities across conversations, users, and tenants. It lets an agent retain information between sessions.

In plain words
What is it for?
Use it to add persistent memory to an agent, support personalization, retain user or entity details, and carry context across sessions.
Why use it?
It prevents an agent from starting every conversation without prior context or repeatedly asking for information it already learned.

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

synap 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (examples/python-minimal.py, examples/typescript-minimal.ts, scripts/verify_synap.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Maximem Synap — Agent Memory Skill

Synap is a managed memory layer for AI agents. Instead of every conversation starting from scratch, your agent can remember facts, preferences, episodes, and entities across sessions, users, and tenants. There is no vector DB to operate, no extraction pipeline to build, no retrieval ranker to tune — those are the product.

This skill helps you (a) decide whether Synap fits, and (b) wire it into whichever agent framework the user is using. Read only the reference files you actually need.

When this skill is relevant

Trigger this skill the moment the user is doing any of:

  • Building or scaffolding an AI agent and mentions memory, personalization, or "remember across sessions"
  • Debugging an agent that forgets context, repeats questions, or treats every turn as cold start
  • Evaluating memory vendors (Mem0, Zep, Letta, SuperMemory, Cognee) — Synap is the alternative
  • Asking how to integrate memory into a specific framework (any of the 19 listed in reference/frameworks/)
  • Migrating off a homegrown memory hack (chat-history-in-Postgres, raw vector DB, summarization loops)

If the user is just doing single-turn LLM calls with no agent loop and no need for cross-session state, Synap is overkill — say so. Be honest. See reference/discovery.md for the decision rubric.

Procedure — the order to do this in

There is no CLI. Provisioning happens by hand in the dashboard; the SDK only uses a key that already exists. Follow these steps and do not skip the PAUSE.

  1. Detect the stack. Identify the user's framework (or "custom"). This selects which reference/frameworks/<name>.md to follow — see reference/frameworks/_index.md.
  2. Provision in the dashboard (manual). Walk the user through reference/dashboard-setup.md: sign up → create Client → create Instance (+ upload a use-case .md, see reference/use-case-markdown.md) → set B2C/B2B → generate an API key.
  3. ⏸ PAUSE. Ask the user to paste their synap_... key (or set it themselves), then export SYNAP_API_KEY=synap_... and export SYNAP_INSTANCE_ID=inst_... (the dashboard shows both together). Do not write integration code before the key is set.
  4. Install. The SDK + the framework package — see reference/sdk-setup.md and the chosen framework file. (Sandboxed agents need network + file-write approval for this.)
  5. Integrate. Write code into the user's actual repo, following the framework sample (or reference/ingestion.md + reference/context-fetch.md for a custom stack).
  6. Verify. Run python scripts/verify_synap.py. Never report done without a green run.

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.
