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 | $0.00023 | $0.00604 |
| Opus 5.5 | $0.00009 | $0.00242 |
| Sonnet 5.5 | $0.00005 | $0.00121 |
| Haiku 4.5 | $0.00002 | $0.00060 |
Grade A, and why
code-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 1mo 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Search (Exa)
Use this skill when the user needs external coding context: official docs, API examples, error explanations, library comparisons, or implementation references that are not already in the repo.
Tool Selection
| Intent | Primary Tool | Notes |
|---|---|---|
| Find docs, examples, API syntax, or error reports | web_search_exa |
Start here for most lookups; include language/library/version in the query. |
| Read official docs or a promising result | web_fetch_exa |
Fetch 1-3 high-signal URLs after discovery. |
| Need a concise grounded explanation | web_answer_exa |
Best for direct questions; ask for citations and short code snippets. |
| Compare libraries or approaches across sources | web_research_exa |
Use only when enabled and the answer needs synthesis, not a quick lookup. |
| Find similar docs or examples from one strong page | web_find_similar_exa |
Use when a seed URL is clearly relevant. |
If web_research_exa or web_search_advanced_exa is unavailable, do not pretend it can be used. Fall back to web_search_exa plus selective web_fetch_exa.
Query Writing
- Include the language, framework/library, and version when known:
TypeScript 5.7 TypeBox Object additionalProperties. - Include exact identifiers, error strings, function names, or package names when available.
- Prefer official docs, release notes, issue trackers, and maintainer-authored examples before blogs.
- For debugging, include the error class/message and runtime context.
Recommended Parameters
web_search_exa{ "query": "TypeScript 5.7 TypeBox additionalProperties examples", "numResults": 5 }
web_fetch_exa{ "urls": ["https://example.com/docs/page"], "maxCharacters": 5000 }
web_answer_exa{ "query": "How does TypeBox validate additionalProperties in TypeScript?", "systemPrompt": "Prefer official docs and concise code snippets." }
web_research_exa{ "query": "Compare TypeScript runtime validation libraries for backend APIs, focusing on schema reuse, performance, and ergonomics.", "systemPrompt": "Prefer official docs, maintainer posts, and recent benchmarks. Call out uncertainty.", "outputSchema": { "type": "text" } }
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.
- 1mo ago First seen · 47 lines · 23 tokens per session scan A f9873371503e
code-search is a skill published in the GitHub repository feniix/pi-extensions (25 stars, last pushed 3d ago), licensed MIT. It adds 23 tokens to every session and 604 once invoked, about $0.0001 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.
