When your agent uses it

Workbook context is insufficient and fresh external references are needed
Tasks that involve Web search
Tasks that involve Excel spreadsheets

Example prompts

“/web-search”

Requirements

Compatibility (from SKILL.md): Requires Pi for Excel integration "web_search" to be enabled. Works immediately with Jina (default); Serper/Tavily/Brave require an API key.

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Open /tools (or /extensions → Connections tab).
Enable external tools.
Enable Web Search for session and/or workbook scope.
(Optional) Choose a different provider and set its API key — Jina works by default with no configuration.

What it can do on your machine

Read from SKILL.md and the folder at commit a3cea8f. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires Pi for Excel integration "web_search" to be enabled. Works immediately with Jina (default); Serper/Tavily/Brave require an API key.
From compatibility in the SKILL.md frontmatter.

Context cost

Web Search loads about 410 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 146 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~410

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
