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 | $0.01797 | $0.01797 |
| Opus 5 | $0.00898 | $0.00898 |
| Sonnet 5 | $0.00359 | $0.00359 |
| Haiku 4.5 | $0.00180 | $0.00180 |
Grade A, and why
notion-skills CLAUDE.md 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.
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.

Claude Code Integration Guide
This document provides instructions for how Claude Code should interact with the Notion Skills plugin.
Plugin Registration
This plugin provides four specialized skills that automatically activate when relevant:
{
"skills": [
"knowledge-capture",
"meeting-intelligence",
"research-documentation",
"spec-to-implementation"
]
}
Skill Activation Triggers
Knowledge Capture
Claude should activate this skill when the user:
- Asks to organize or document conversations
- Wants to convert meeting notes to structured documentation
- Requests to extract decisions or action items from discussions
- Needs to create knowledge base articles from discussions
- Asks to archive or preserve conversations
Example triggers:
- "Organize these meeting notes"
- "Document this discussion in Notion"
- "Extract action items from the meeting"
- "Turn this transcript into a knowledge base article"
Meeting Intelligence
Claude should activate this skill when the user:
- Asks to prepare for an upcoming meeting
- Wants to gather context about a meeting topic
- Requests a comprehensive meeting agenda
- Needs background materials for a meeting
- Asks to review past interactions with meeting attendees
Example triggers:
- "Help me prepare for my meeting with..."
- "Create an agenda for tomorrow's meeting"
- "What do I need to know about..."
- "Gather context for this meeting"
Research Documentation
Claude should activate this skill when the user:
- Asks to research a specific topic
- Wants to document research findings
- Requests a competitive analysis or market research
- Needs to create a literature review
- Asks to compare technologies or frameworks
Example triggers:
- "Research [topic] and document findings"
- "Create a competitive analysis for..."
- "Compare [option1] vs [option2]"
- "Build a knowledge base about..."
Spec-to-Implementation
Claude should activate this skill when the user:
- Asks to convert a specification into an implementation plan
- Requests task breakdown for a feature or project
- Wants to create a project timeline with estimates
- Needs to generate a roadmap from requirements
- Asks to set up implementation tracking
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.
- 10d ago First seen · 318 lines · 1,797 tokens per session scan A 3f2330a34857
notion-skills CLAUDE.md is an instructions file published in the GitHub repository tommy-ca/notion-skills (62 stars, last pushed 10mo ago), licensed MIT. It adds 1,797 tokens to every session, about $0.0090 per session on Opus 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.
