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 | $0.00123 | $0.02323 |
| Opus 5.5 | $0.00049 | $0.00929 |
| Sonnet 5.5 | $0.00025 | $0.00465 |
| Haiku 4.5 | $0.00012 | $0.00232 |
Grade A, and why
workspace-explorer 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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Notion Workspace Explorer
Explore and navigate Notion workspaces through Notion's MCP server, which pi connects with its built-in MCP support.
For detailed reference on specific operations, see:
references/databases.md— Database schemas, DDL types, views, queries, property formatsreferences/write-operations.md— Create/update pages, comments, move, duplicate, trashreferences/failure-modes.md— Error table and tips (read when something fails)
Prerequisites
Notion's tools are named mcp__notion__<tool>, with - replaced by _: notion-search is mcp__notion__notion_search. This skill uses Notion's own names. They are deferred: load the ones you need with tool_search before calling them, or call them from a codemode script.
tool_search ranks by matching words, not exact names, so a tool's own name often loads a similar tool instead (notion-query-data-sources loads notion-query-multiple-data-sources). These queries load the right tool, also with a mcp__notion prefix. Before the first Notion call, load every tool the task needs at once: send these tool_search calls in parallel as separate tool calls (tool_search is not available inside codemode), each with "limit": 1:
| Tool | tool_search query |
|---|---|
notion-search |
search connected sources |
notion-fetch |
notion fetch |
notion-query-data-sources |
faithful structured rows |
notion-query-meeting-notes |
query meeting notes |
If no Notion tools are found, or calls fail because Notion needs sign-in, ask the user to run /mcp login notion. Do not try to sign in yourself.
A user with several Notion workspaces has one server per workspace, such as mcp__notion__* and mcp__notion_work__*. Use the server whose name or description matches the workspace the user means; if that is unclear, ask which workspace before calling. Pages and IDs from one workspace do not exist in another.
Search
Start with just a query; add other parameters only to narrow the search:
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.

workspace-explorer is a skill published in the GitHub repository feniix/pi-extensions (25 stars, last pushed 2d ago), licensed MIT. It adds 123 tokens to every session and 2,323 once invoked, about $0.0005 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.
