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

Annotations declare the mutation profile (readOnly=false, idempotent=false, destructive=false) but nothing about side effects. The description adds substantive context beyond that: default value is false, cached results and crawler copies may persist after disabling (a non-reversible effect), and the confidential-content warning. Strong disclosure for a mutation tool.

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?

Front-loads the core action and default in the first two sentences, then layers prerequisites and warnings. Dense but each sentence carries information. Slightly compressed into a run-on list of caveats.

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?

No output schema exists and this is a mutation, so the description correctly covers preconditions, side effects, and irreversibility. It is nearly complete except for the unexplained proposal_id parameter, which leaves a gap given the 0% schema coverage.

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% and neither parameter is meaningfully explained. The description implies the boolean default ('Default false') but never clarifies what 'indexable' toggles versus what 'proposal_id' identifies. With no schema help, the description fails to compensate for the gap.

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?

States a specific action on a specific resource: allowing/disallowing search-engine indexing of public pages. This is distinguishable from visibility-style siblings by the word 'indexing', though it never names the sibling it should be contrasted with (e.g., set_visibility). Clear purpose, no explicit sibling routing.

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?

Provides real preconditions: 'Requires public visibility and publishing eligibility' and 'Making the link private or passcode-protected disables indexing.' It also instructs confirmation before enabling. It stops short of naming alternative tools for related settings, so it earns a 4 rather than 5.

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