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.

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 | $0.00220 | $0.04006 |
| Opus 5.5 | $0.00088 | $0.01602 |
| Sonnet 5.5 | $0.00044 | $0.00801 |
| Haiku 4.5 | $0.00022 | $0.00401 |
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 2d 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.

Maximem Synap — Agent Memory Skill
Synap is a managed memory layer for AI agents: facts, preferences, episodes and entities remembered across sessions, users and tenants, with no vector DB, extraction pipeline or ranker to run. For single-turn LLM calls with no agent loop and no cross-session state, Synap is overkill: say so (reference/discovery.md).
Public prompt (asks if Synap fits, no code): follow reference/public-start.md first; on yes it runs <cli> auth login --purpose onboarding, then step 2.
Procedure: onboarding a project end to end
Never guess. If anything is unclear, stop and ask the human. Full steps and sign-out message: reference/onboarding-details.md; questions, tips, failures: reference/onboarding-ask-rules.md; CLI: reference/dashboard-setup.md.
CLI. <cli> means maximem-synap from PATH if maximem-synap --version reports 0.3.3 or newer (the session commands do not exist before), otherwise npx @maximem/synap-cli@latest (needs Node and Python 3.10+). If the prompt names an environment, add --env <name> to every CLI command (or export SYNAP_ENV=<name>) and never say it to the human; a one-time code only works on the server that issued it.
Quick reference. Put --json or --output json before the subcommand; use the full inst_... id, never a truncated table id. If SYNAP_API_KEY is set in your shell, CLI calls fail with 401 or 403: run them with env -u SYNAP_API_KEY <cli> ....
- Sign in.
<cli> auth login --code <syn_ob_...> --agent-name <name>, with your own lowercase product name (claude-code,cursor,codex,windsurf,other). A missing, expired or used code at this first sign-in is the one case where you say: copy a fresh prompt from the dashboard. The key lasts 7 days; neverauth refreshit. Pin your session: login prints your profile name; put--profile <name>before the subcommand of EVERY CLI command (<cli>below includes it; your shell keeps no variables between calls,SYNAP_PROFILEworks only if it does). Never log out or touch a profile that is not yours. On a 'pin your profile' refusal (exit 2) read the names in the message and pin your own. - State.
<cli> onboard statusshows this session's steps and a read-only list of OTHER sessions. Trust only steps you reported yourself; other sessions are someone else's work: never act on them, answer their questions, or skip drafting, approval or creation because they look done. Re-running the prompt is safe. 2b. What exists (right after step 2, before step 3).<cli> instances list --json; tell the human in plain words each instance (name, what it is for if known, ready, being built or failed:reference/instances-explained.md). If any exist, ask ONE question with your recommendation and tip: reuse one or create a new one. Recommend reuse only if it is for THIS agent (one instance serves one agent, /concepts/agent-topologies). Reuse = the existing-instance variant below.
What ships with it
49 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

synap is a skill published in the GitHub repository maximem-ai/maximem_synap_sdk (77 stars, last pushed yesterday), licensed Apache-2.0. It adds 220 tokens to every session and 4,006 once invoked, about $0.0009 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 2026-08-30.
