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 | $0.00024 | $0.00340 |
| Opus 5 | $0.00012 | $0.00170 |
| Sonnet 5 | $0.00005 | $0.00068 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
native-web-search 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 4d 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.
What it actually says
Native Web Search
Use this skill to run a fast model with native web search enabled and get a concise research summary with explicit full URLs.
Script
search.mjs
Usage
Run from this skill directory:
node search.mjs "<what to search>" --purpose "<why you need this>"
Examples:
node search.mjs "latest python release" --purpose "update dependency notes"
node search.mjs "vite 7 breaking changes" --purpose "prepare migration checklist"
Optional flags:
--provider openai-codex|anthropic--model <model-id>--timeout <ms>--json
Output expectations
The script instructs the model to:
- search the internet for the requested topic
- provide a concise summary for the given purpose
- include full canonical URLs (
https://...) for each key finding - highlight disagreements between sources
Notes
- No extra npm install is required.
- If module resolution fails, set
PI_AI_MODULE_PATHto@earendil-works/pi-ai'sdist/index.jspath. - If OAuth helper resolution fails, set
PI_AI_OAUTH_MODULE_PATHto@earendil-works/pi-ai'sdist/oauth.jspath. - For OAuth providers, the script can fall back to a still-valid cached
accesstoken from~/.pi/agent/auth.json.
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.

native-web-search is a skill published in the GitHub repository mitsuhiko/agent-stuff (3,044 stars, last pushed 2d ago), licensed Apache-2.0. It adds 24 tokens to every session and 340 once invoked, about $0.0001 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.
