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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered. The description adds real value beyond that: success is gated on a browser paint acknowledgement, and a failed render preserves the previous component, i.e. the pre-condition and failure/rollback semantics of a destructive publish.

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?

Three tight, front-loaded sentences that each carry distinct information: the action, the validation precondition, and the failure/rollback behavior. No filler, though the validation and acknowledgement clauses are densely packed.

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 destructive, open-world mutation with 6 required params, no output schema, and 0% schema coverage, the description covers operation semantics well (validation, acknowledgement, rollback) but leaves the identifiers and controlToken unexplained, so an agent cannot fully reason about the inputs.

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% across 6 required parameters, so the description must carry the burden and largely does not. It gestures at expectedRevision ('validating workspace revision'), version ('exact reviewed draft version'), and review ('reviewed'), but gives no meaning for operationID or controlToken and no format/handling guidance.

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 ('publishes an exact reviewed draft version') and adds qualifying conditions (validated revision, target dimensions, paint acknowledgement). It is clearly distinguishable from read_draft/update_draft/prepare_draft in intent, though it never names a sibling explicitly.

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?

Usage is implied rather than stated: the phrase 'exact reviewed draft version' suggests a completed review stage, and validation language hints at prerequisites. But there is no explicit when-to-use/when-not-to-use guidance or routing to prepare_draft, discard_draft, or cancel_operation.

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