alterlab_crawl_status

Monitor crawl progress and retrieve scraped pages by polling status with a crawl ID. Returns status: queued, running, completed, failed, cancelled.

Instructions

Poll the status and results of an ongoing or completed crawl. Call this after alterlab_crawl to check progress and retrieve scraped pages. Status values: queued, running, completed, failed, cancelled. When completed, results contains the scraped page content.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
crawl_idYesCrawl ID returned by alterlab_crawl
Behavior3/5

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

No annotations provided, so description carries full burden. It explains polling behavior and that results are present when completed, but does not specify idempotency, whether results persist after first read, or any side effects. Adequate but not deep.

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

Conciseness5/5

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

Two sentences with no wasted words. Front-loaded with purpose, then adds details on status values and output. Excellent conciseness.

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

Completeness4/5

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

No output schema, so description explains that 'results contains the scraped page content' when completed. Lists status values. Could mention if results are paginated or size limits, but complete enough for a simple status poll tool.

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 coverage is 100%, so baseline 3. Description adds context by noting crawl_id is returned by alterlab_crawl, helping the agent understand the parameter source. Slight improvement over bare 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?

Description clearly states it polls status and results of a crawl, explicitly naming the action and resource. It distinguishes itself from siblings like alterlab_crawl and alterlab_crawl_cancel by specifying it is the follow-up call for progress checking.

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

Usage Guidelines4/5

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

Explicitly says 'Call this after alterlab_crawl' and lists status values, providing clear context. Does not include explicit when-not-to-use or alternative tools, but given sibling set, this is the only status poll for crawls.

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