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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered structurally. The description adds genuinely new information with 'Free' (cost) and hints the return content ('changedAt revisions'), but says nothing about pagination, grant volume, or response shape.

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 clauses, front-loaded with the operation and its output, then cost/safety, then the doc pointer. No filler sentences.

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?

With no parameters, no output schema, and rich annotations, the description covers purpose, cost, non-mutation, and roughly what comes back. The phrase 'grants' and the 'Fields:' URI are left unexplained, which is the main remaining gap.

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 tool takes zero parameters, which is the baseline-4 case; there is no parameter semantics burden. The 'Fields: soclo://tools/...' line points at a schema/doc resource rather than describing any input.

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?

A specific verb ('Read all') plus a specific resource ('campaign platform auto-pause grants and their changedAt revisions'). It is clearly distinct from soclo_ads_watch_auto_pause_set by the read/set verb split, though it never names the 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?

'Free; no permission is changed' implies a safe, zero-cost inspection call, most plausibly a pre-check before soclo_ads_watch_auto_pause_set, but that sequencing is left to inference. No explicit when-to-use or when-not-to-use statement is given.

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