web

A toolkit for getting information from websites, including ordinary pages, JavaScript-heavy apps, search results, screenshots, PDFs, and structured data.

In plain words
What is it for?
Use it to search the web, read or crawl pages, capture screenshots or PDFs, extract data, and check claims against live sources.
Why use it?
It provides different ways to fetch and inspect web content when a simple page request is not enough.

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.

Made for: Claude Code, Codex.

Per session 150 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 2,107 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

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.

Security

Grade A, and why

web 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 yesterday.

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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Web Content Operations

All web operations use shell scripts in ${CLAUDE_PLUGIN_ROOT}/scripts/. Output goes to .claude-crawl/ in the project root to protect the context window from large content.

Before any operation: mkdir -p .claude-crawl/{reads,searches,crawls,extractions,reranks,ground,screenshots,pdfs}

WebFetch calls are automatically intercepted and routed through Jina Reader for cleaner markdown output. Set CLAUDE_CRAWL_NO_INTERCEPT=1 to disable this behavior and use WebFetch directly. Run check-auth.sh --verbose to see which services are available.

Routing Table

Choose the right tool based on what you have and what you need:

HAVE                      NEED                        USE
─────────────────────────────────────────────────────────────────────
Topic/question            Search results              jina-search.sh or fc-search.sh
URL, static page          Clean markdown              jina-read.sh
URL, JS-heavy/SPA         Rendered content            fc-scrape.sh
URL, need visual capture  Screenshot or PDF           cf-page.sh --format screenshot|pdf
URL, need structured data JSON extraction (AI)        cf-page.sh --format json --ai-prompt "..."
Domain                    All URLs on site            fc-map.sh
Multiple URLs, bulk       Multi-page content          cf-crawl-start.sh or fc-crawl.sh
Statement/claim           Fact verification           jina-ground.sh
Multiple results          Ranked by relevance         jina-rerank.sh

How to decide between similar tools

Search: Use jina-search.sh for general web search (fast, returns full content). Use fc-search.sh when you need Firecrawl-specific features like --scrape (auto-scrapes each result) or want an alternative search provider.

Single page fetch: Start with jina-read.sh — it's fastest and cheapest. If the result is thin (< 100 words, no headings — the script warns you), escalate to fc-scrape.sh which renders JavaScript. If you need Cloudflare's AI extraction or screenshots, use cf-page.sh.

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.

Changes

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 is a skill published in the GitHub repository hex/claude-crawl (1 stars, last pushed 5mo ago), licensed MIT. It adds 150 tokens to every session and 2,107 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings.
