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 | $0.00084 | $0.00845 |
| Opus 5 | $0.00042 | $0.00423 |
| Sonnet 5 | $0.00017 | $0.00169 |
| Haiku 4.5 | $0.00008 | $0.00085 |
Grade A, and why
notion-bank 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notion Bank — Documentation Hub
Use notion-bank MCP to keep implementation plans and service documentation in Notion. MCP tools are the only I/O to Notion; this skill teaches when and how to call them and when to chain other skills first.
When to Use
- User invokes
/notion-bank - Create or revise an implementation plan that should live in Notion
- Document a hinha service (or any service under the Plans root)
- Surgical section edits to an existing Notion plan
- Migrate local markdown into the plan bank
Prerequisites
- notion-bank MCP is connected in the host (Cursor / Claude / Codex / etc.)
- Never ask for
CLIENT_ID,CLIENT_SECRET, Notion tokens, broker URLs, ornpm serve - End-user auth is browser OAuth via mcp.notion.com (automatic)
Setup Gate (always first)
- Call
plan_status - If no auth:
plan_oauth_login(or any Notion tool — browser opens automatically) - If no Plans root: ask only for the user's Plans root Notion page URL →
plan_configure - Never invent page IDs or tokens
See references/mcp-tools.md for the full tool cheat sheet.
Skill Chaining (conditional — not a fixed pipeline)
Read references/chaining.md. Summary:
| Situation | Chain |
|---|---|
| New / ambiguous feature or plan | superpowers:brainstorming → superpowers:writing-plans, then Notion write |
Existing goal.md for Claude /goal |
optimize-goal (tighten file first), then Notion write |
| Docs-only revise of a known plan | Skip brainstorming; use engineering checklist + Notion tools |
| Health / fitness goals | Do not invoke health goal-analyzer — out of scope |
Always run the engineering goal checklist in references/engineering-goals.md before writing.
Write Path
Full create / replace:
plan_ensure_serviceif the service page may be missingplan_upsert(markdown string) orplan_migrate(local file)- Return the Notion page URL
What ships with it
3 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.

notion-bank is a skill published in the GitHub repository hinha/notion-bank-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 84 tokens to every session and 845 once invoked, about $0.0004 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 2026-08-31.
