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

Goes beyond the annotations (destructiveHint=true, idempotentHint=true, openWorldHint=true) by naming the concrete safety protocol: preview required for spending/deletion, owner approval, confirm:true, and the same requestId for confirmation and outcome recovery. It does not state which fields trigger the spending/deletion path or how to poll status, which is the remaining 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?

Front-loaded verb+resource and the safety rule comes early, which is good. But the trailing 'Fields: soclo://tools/soclo_ads_update_ad_group_assets' is an opaque pointer that consumes space without conveying anything an agent can act on, and the phrasing is telegraphic to the point 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 10-parameter destructive mutation with nested payload objects and no output schema, the confirmation flow is covered but the payload shape (updates array, 1-20 items, per-asset types), the adSetId scoping, and the status/recovery tool (soclo_ads_operation_status) are not referenced. Adequate to start the preview step, not complete enough to execute confidently.

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?

The description reinforces the two most consequential parameters (confirm and requestId reuse for confirmation and recovery), which matches their schema descriptions. It says nothing about payload.updates, adSetId, or the expectedBudgetAmount/Currency/BudgetType preview-echo parameters, and with 60% schema coverage that leaves real gaps.

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 verb and resource ('Update ad-group assets') consistent with the tool name, but doesn't say what an 'asset' is here (sitelinks, callouts, structured snippets, final URLs) nor how this differs from sibling tools like soclo_ads_attach_ad_group_assets, soclo_ads_remove_ad_group_assets, or soclo_ads_update_campaign_assets. The purpose is identifiable but the scoping decision still requires opening the schema.

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?

Gives a real procedural rule: preview first, then owner-approved confirm:true with the same requestId, and only treat the claim as live when status is active. However it offers no guidance on when to choose this tool over the attach/remove/update-campaign-assets siblings, which is the main ambiguity an agent faces.

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