What is notion-memory?

A memory workflow that stores and retrieves user and project context in a Notion workspace. Notion is a workspace for notes and documents, and persistent memory means information can be reused in later sessions.

Use it to save and look up profile information, project state, decisions, and other organized long-term context in a Notion page.

It helps an assistant remember preferences, decisions, and project details instead of rebuilding that context every time.

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	$0.00000	$0.01590
Opus 5	$0.00000	$0.00795
Sonnet 5	$0.00000	$0.00318
Haiku 4.5	$0.00000	$0.00159

Security

Grade A, and why

notion-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 3d 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.

Notion Memory — Long-Term Memory for Claude Cowork & Claude Code

You are Claude running in Cowork mode or Claude Code. This skill gives you persistent long-term memory by storing and retrieving context from the user's Notion workspace. Use it to remember facts, decisions, preferences, and project state across sessions.

This works in both environments:

Cowork: Connect Notion via Settings → Connectors → Notion
Claude Code: Add a Notion MCP server to your Claude Code config (.mcp.json or settings)

Prerequisites

The user must have Notion MCP tools available (connected via Cowork or configured in Claude Code)
If Notion tools are not available, tell the user how to connect based on their environment:
- Cowork: "Connect Notion via Settings → Connectors → Notion"
- Claude Code: "Add a Notion MCP server to your .mcp.json config"

Memory Architecture

All memory lives in a single Notion page called "Claude Memory" in the user's workspace. Under that page, you create child pages organized by category:

Claude Memory (root page)
├── Profile          — User preferences, name, role, communication style, recurring instructions
├── Projects         — One sub-page per active project with goals, status, decisions, context
├── Decisions Log    — Key decisions made across sessions with date and reasoning
├── Session Archive  — Summaries of past sessions (most recent first)
└── Quick Facts      — Short key-value facts the user has told you to remember

Core Workflows

1. Initialize Memory (First Time Setup)

When the user first asks you to remember something or says "set up memory", and no "Claude Memory" page exists yet:

Use notion-search to look for a page titled "Claude Memory"
If not found, use notion-create-pages to create the root page "Claude Memory"
Create the five child pages listed above under the root page
Confirm to the user: "I've set up your memory space in Notion. I'll use it to remember things across our sessions."

Generates and maintains a design manifest for visual consistency. In existing projects, reads current styles and documents the design language. In new projects, asks a few questions and generates a starter manifest. The post-edit hook reads the manifest and flags deviations.
