Service guide for one service_id: with view=guide it returns the first request, preparation, validation checks and access requirements. Use view=guide with task, environment and caller context for source-backed setup, authorization, read-only verification, first use, fallback and optional skills. Public access; reuse existing provider connections.

+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so safety is covered. The description adds useful access context ('Public access; reuse existing provider connections') but does not explain side effects, response shape, or how caller context affects returned guidance.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is reasonably front-loaded with the service guide purpose, but it repeats 'with view=guide' and is dense with jargon. It is not excessively long, but some sentences could be tightened.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
This is a complex tool with a required service_id, an enum view, and a deeply nested context schema, plus no output schema. The description is far too thin for that complexity: it does not explain view=full, most context fields, how caller_profile is used, or what the guide output contains.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must carry the burden for three top-level parameters and a massive nested context object. It only mentions view=guide and alludes to 'task, environment and caller context' without defining any context fields or explaining how they alter results.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it is a 'Service guide for one service_id' and explains what view=guide returns, but it never clarifies what the default view=full returns. It also does not distinguish inspect_site from siblings such as inspect_documentation or get_agent_path.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It gives relevant scenarios for view=guide ('setup, authorization, read-only verification, first use, fallback and optional skills'), which implies when to use that mode. However, it never states when to use view=full, when to choose inspect_site over inspect_documentation, or any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
