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 | $0.00029 | $0.03116 |
| Opus 5 | $0.00015 | $0.01558 |
| Sonnet 5 | $0.00006 | $0.00623 |
| Haiku 4.5 | $0.00003 | $0.00312 |
Grade A, and why
web-search scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 324 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Search
Web search, scraping, and content extraction for AI coding agents. Zero API keys required. Five tools organized in fallback chains: WebSearch and Crawl4AI as primary, Jina as secondary, duckduckgo-search and WebFetch as fallbacks. Use when your agent needs web information -- finding pages, extracting content, or conducting research.
Terminology used in this file:
- Playwright: Browser automation framework used by Crawl4AI for JavaScript-rendered pages.
- SPA: Single-page application; content is rendered dynamically in JavaScript.
- MCP: Model Context Protocol, a standard for exposing tool servers to AI agents.
Setup
python3 -m pip install crawl4ai duckduckgo-search
crawl4ai-setup
- Claude Code: copy this skill folder into
.claude/skills/web-search/ - Codex CLI: append this SKILL.md content to your project's root
AGENTS.md
For the full installation walkthrough (prerequisites, verification, troubleshooting), see references/installation-guide.md.
Staying Updated
This skill ships with an UPDATES.md changelog and UPDATE-GUIDE.md for your AI agent.
After installing, tell your agent: "Check UPDATES.md in the web-search skill for any new features or changes."
When updating, tell your agent: "Read UPDATE-GUIDE.md and apply the latest changes from UPDATES.md."
Follow UPDATE-GUIDE.md so customized local files are diffed before any overwrite.
Quick Start
Run this minimal fallback-safe sequence:
# 1) Find candidate pages
python3 -c "from duckduckgo_search import DDGS; import json; print(json.dumps(DDGS().text('your query', max_results=5), indent=2))"
# 2) Extract one page quickly (no local deps)
curl -s "https://r.jina.ai/http://example.com/article" | head -80
# 3) Escalate to Crawl4AI if JS rendering is needed
crwl https://example.com/app --f markdown --bypass-cache
Use this routing rule: search with WebSearch first, extract with Jina/WebFetch for simple pages, escalate to Crawl4AI for JS-heavy targets.
What ships with it
7 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.

web-search is a skill published in the GitHub repository buildoak/fieldwork-skills (15 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 29 tokens to every session and 3,116 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
