Crawler policy guide

crawler_policy_guide
Read-onlyIdempotent

Static reference of 15 known AI crawlers and control tokens (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended...): owner, purpose, whether each drives AI citations or training, plus rules of thumb. Use to decide which bots to allow or block. No site is fetched. Do NOT use to audit a real site (use check_ai_readiness) or to produce rules (use robots_txt_for_ai).

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

  6. First observed

TDQS

A4.4/5.0
Behavior3/5

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

Annotations already declare readOnly, idempotent, closed-world, non-destructive, so the safety profile is covered. The description adds useful context beyond that: "No site is fetched" and the fixed size of 15 entries imply a static, possibly stale knowledge base. It does not say how current the bot list is or how the citation-vs-training determination is made, which is the main remaining behavioral gap.

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?

Four compact sentences: what it contains, what it is for, a safety clarification, and routing exclusions. Content inventory is front-loaded and nothing is repeated from the annotations or title.

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?

With an output schema present, the description needn't describe return values, and it covers scope, size, fields, use case, and exclusions. The only missing piece is freshness/coverage limits of the bot list, which matters for a static reference but is not stated.

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?

Zero parameters, so baseline 4 applies. The description correctly implies a parameterless lookup and adds no misleading input expectations.

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?

States a specific resource and scope: a static reference of 15 named AI crawlers with owner, purpose, and citation-vs-training classification. The concrete bot names (GPTBot, OAI-SearchBot, ClaudeBot) make it unmistakable what the tool returns and how it differs from the sibling tools.

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?

Gives an explicit use case ("decide which bots to allow or block") and two explicit exclusions with named alternatives: check_ai_readiness for auditing a real site, robots_txt_for_ai for producing rules. An agent can route correctly without opening any schema.

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