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

It adds two genuinely useful behavioral facts beyond the annotations: the entitlement requirement and 'Notify only; never pauses ads', which bounds the blast radius of an otherwise destructiveHint=true mutation. It says nothing, though, about upsert overwrite semantics, what confirm/confirm_live/dry_run do, or what happens to fields omitted from a call — critical for a 34-parameter mutating 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?

Three short, front-loaded sentences with zero filler, and the scope statement is placed where an agent will read it. The tradeoff is that the terseness ('Admin + Pro, Agency, or the SEO add-on') is compressed to the edge of ambiguity.

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 34-parameter, zero-required, fully undocumented mutation endpoint, three sentences cannot be sufficient; the output schema helps with returns but nothing helps with inputs. An agent can identify the tool's purpose but cannot confidently populate or omit the many condition/threshold/delivery fields.

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 34 parameters and the description supplies no parameter meaning whatsoever — not even for high-consequence flags like dry_run, confirm, confirm_live, threshold, operator, or rule_id. The only implicit hint is that 'update' implies rule_id, which is far too thin to call semantics.

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 opens with a specific verb and resource: 'Create or update a SEO/AEO alert rule', which makes the upsert behavior explicit. It does not name or distinguish itself from the close siblings automate_upsert_alert_rule and automate_upsert_automation_rule, so an agent must infer the difference from the tool name alone.

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?

'Admin + Pro, Agency, or the SEO add-on' gives a real prerequisite gate (role plus plan entitlement) that tells the agent when the call can succeed. However, there is no guidance on when to pick this over upsert_alert_rule/upsert_automation_rule, nor on when to set rule_id (update) versus omitting it (create).

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