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

Annotations already declare readOnly=false, idempotent=true, openWorld=true, and destructive=false. Beyond that, the description discloses the concrete side effect – one bounded public HTML fetch rather than a CMS write – which is genuinely useful context an agent cannot get from annotations. It does not say whether the check is synchronous or returns a job handle, leaving one 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.

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

Two tightly packed sentences with no filler; the affirmative scope comes first and the exclusion list follows immediately.

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?

For a no-output-schema mutation with four required parameters, the description covers what is recorded, what side effect fires, and what the tool is not. The main missing piece is the outcome shape of the queued HTML check (async job id vs immediate result) and the relationship to read_page_deployments.

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 coverage is 60%: reviewed, deployedAt, and idempotencyKey are documented in the schema, including the 90-day window and retry guidance. The description adds no parameter detail and leaves workspace and documentId undocumented anywhere beyond type and length, so it neither compensates nor regresses.

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 verb and resource: declaring that already-reviewed changes were applied to their mapped page. The second sentence further bounds the action by ruling out CMS publishing, paid research, and rank-lift proof, so an agent can distinguish this from prepare_page_changes or read_page_deployments.

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?

The prerequisite is clear from 'reviewed saved changes were applied' – the work must already be prepared and reviewed. The negative scoping ('not CMS publishing, paid research or proof of ranking lift') prevents misuse, but no sibling tool is named as the alternative for those adjacent tasks.

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