Read-onlyIdempotent

Extract readable text and citations from web pages, PDFs, Office files, and YouTube transcripts by providing a single URL. Automatically picks the best extraction method.

Instructions

Read a single URL and get back its content — web pages (including JavaScript-heavy sites), PDFs, Word/PowerPoint files, and YouTube transcripts — picking the best extraction method automatically. Returns readable text plus a ready-to-use citation. Reach for this when you already have a URL and want what's on the page; use search_and_scrape to find and read in one step, or web_search when you only need links. Modes: full (default, cleaned text), preview (a fast first look), and raw (verbatim page bytes with no sanitization — only for inspecting source like JSON or HTML, and the bytes are untrusted, so never execute or render them). Blocked pages and other failures return structured JSON (kind, retryable, suggestedAction). Results stay fresh for 1 hour.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlYesThe HTTP/HTTPS URL to extract content from. Supports web pages, PDFs, DOCX, PPTX, and YouTube video URLs.,required
modeNoExtraction depth: full (default, cleaned readable text up to max_length), preview (first 5000 bytes, faster), or raw (verbatim unsanitized bytes — see tool description before using).
max_lengthNoMaximum content length in bytes (default: 50000). Reduce for faster responses when you only need a summary.
sessionIdNoLink this page to a sequential_search session. The URL and title are automatically recorded as a source for recovery after context loss.

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds rich behavioral context beyond annotations: automatic extraction method selection, citation return, mode specifics, failure JSON format with retryable and suggestedAction, and 1-hour cache freshness. No contradictions with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with logical flow: core function, usage guidance, mode details, error handling, freshness. Each sentence is informative, though slightly verbose; no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers all key aspects: supported content types, mode behaviors, error handling format, caching duration, and output includes citation. Given the output schema exists, return values are adequately described.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers 100% of parameters, but the description adds crucial context: explains mode options in depth, warns about raw mode trust issues, and clarifies sessionId links to sequential_search. Adds significant value beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool reads a single URL and extracts content from various formats (web, PDFs, YouTube). It explicitly distinguishes itself from siblings like search_and_scrape and web_search, making the purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit guidance on when to use this tool (when you have a specific URL) and when to use alternatives. Also details the three modes and their appropriate use cases, helping the agent decide.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
