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

Adds substantial context beyond the annotations: it is slow (several LLM calls, 1-3 minutes), synchronous, returns a concrete payload (new title, meta description, full HTML, before/after), and publishes nothing. It also discloses failure and refusal behavior — safety-check failure reverts the row to "proposed" with a reason, and a hand-edited draft causes refusal because it would be overwritten — none of which appears in the structured fields.

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-loaded with purpose and scoping, then cost, then return value, then routing — a sensible order with no filler. It is a dense single paragraph with many parenthetical clauses, which costs a little readability but every sentence carries information.

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 the description compensates by enumerating the return payload. Combined with the latency warning, the non-publishing guarantee, and the failure/refusal paths, an agent has everything needed to call this correctly and set expectations.

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 50%; the description never mentions updateId directly, though it does implicitly characterize it by explaining that "retarget", "sections" and "full" rows behave differently, which helps an agent understand what kind of update it is targeting. The site enum is only documented in the schema, so the description adds partial but not decisive semantic value.

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?

Opens with a specific verb+resource ('Write the improved version of a proposed page update') and immediately scopes it to rows in status "proposed". It distinguishes itself from the neighboring draft tools by explaining that it produces the content, while edit_update_draft, approve_update and dismiss_update act on it afterward.

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?

Explicitly names the downstream alternatives ('Next: edit_update_draft to tweak it, approve_update to publish, or dismiss_update') and states a blocking precondition (refused when a hand-edited draft exists). It doesn't spell out the inverse case — when to prefer edit_update_draft over re-running this — so it stops short of a full when/when-not matrix.

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