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 | $0.00043 | $0.01747 |
| Opus 5 | $0.00022 | $0.00873 |
| Sonnet 5 | $0.00009 | $0.00349 |
| Haiku 4.5 | $0.00004 | $0.00175 |
Grade B, and why
notion scanned grade B with 1 finding 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 yesterday.
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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
Never echo a Notion API token (prefix `ntn_…` for `ntn` OAuth or `secret_…` for integration tokens) in tool output, logs, commits, or PR bodies. The token belongs in `.envrc` (gitignored, `chmod 600`) or `~/.config/ntn/` How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notion
Prefer the official Notion MCP connector when it exposes the requested operation. Notion supports Codex and other clients as well as Claude Code; route by actual tools, not client identity. Use the optional ntn CLI for supported capabilities missing from the connector or a requested script. Run the Pre-flight, preserve the user's write scope and verify resulting content.
Pre-flight (do once per session before any content write)
MCP path only — on the ntn CLI branch, skip this and validate shapes against the REST API responses instead.
- Read the MCP resource
notion://docs/enhanced-markdown-spec— the canonical reference for Notion-flavored Markdown used bynotion-create-pagescontentandnotion-update-pageupdate_content/replace_content. Don't guess Markdown syntax — Notion's flavor diverges from CommonMark in non-obvious ways. - For database row CRUD —
notion-fetchthe target data source first. The fetch returns the current SQLite-style schema. Property names are case-sensitive; expanded keys apply (date:<col>:start | :end | :is_datetime,place:<col>:name | address | latitude | longitude | google_place_id, checkbox__YES__/__NO__, properties literally namedidorurl→ prefixuserDefined:).
Routing — MCP vs CLI
Default — MCP
Inspect the active tool descriptions. Depending on the connector, supported operations can include:
- SQL DDL for schemas —
notion-create-database/notion-update-data-source - View DSL —
notion-create-view/notion-update-view - Block-level comments —
selection_with_ellipsisagainst rendered Markdown - Batch up to 100 rows in one
notion-create-pagescall - Semantic search across connected sources (Slack, GDrive, GitHub, Jira, MS Teams, Sharepoint, OneDrive, Linear)
Use the ntn CLI when its capabilities fit
- File upload to Notion —
ntn files createwhen the active MCP lacks upload support. - Notion Workers / serverless —
ntn workers …when needed tools are absent from the MCP. - Headless / CI / non-interactive — use the supported CLI authentication and output flags for the requested script. A CI job need not have a Claude session; absence of Claude does not imply absence of MCP elsewhere.
- Raw API discovery —
ntn api lsenumerates every endpoint. Useful when an action isn't covered by any high-level MCP tool. - Shell piping —
ntn pages get <id> --json | jq …for ad-hoc data wrangling.
What ships with it
1 file 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.

notion is a skill published in the GitHub repository coroboros/agent-skills (4 stars, last pushed 2d ago), licensed MIT. It adds 43 tokens to every session and 1,747 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
session-wrap
Use when wrapping up a session before ending. 4 parallel subagents detect doc updates, repeated patterns, learning points, and follow-ups, then a verifier deduplicates and presents choices. Triggers on /session-wrap, session wrap, session cleanup, end of session.
skill-factory
A workflow that examines completed session work and turns reusable patterns into Claude Code skills.
shogun-model-switch
A live-switching tool for changing which command-line AI agent, model, and reasoning mode is running. It updates settings, restarts the agent, and refreshes the displayed session information.
caveman-help
Quick-reference card for all caveman modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /caveman-help, "caveman help", "what caveman commands", "how do I use caveman".
relay
Session relay — compresses what's been done so far (writes a one-liner for /compact) and generates a "next task" prompt (a baton) for the user to hand off. Use on requests like "relay / hand off / next session / continue after compact / baton / handoff / clean up context and continue next task." Does not run /compact…
agent-tamagotchi
Terminal pet that lives in your statusline. 12 species, 5 stats (DEBUGGING, PATIENCE, CHAOS, WISDOM, SPEED). Reacts to your workflow - happy when tests pass, sad when builds fail, excited during swarm mode. Deterministic species from user ID.
