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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds cost behavior ('Free') plus a semantic warning that watchConfigured is not enabled/paid status — real value beyond the structured fields. It does not address openWorldHint (external state dependence) or whether the read can fail when no config exists.

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 the resource and the cost/scope caveat in a few short sentences; nothing is padded. The trailing 'Fields: soclo://tools/...' pointer is opaque and reads like an internal artifact rather than useful guidance.

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 output schema, the description does the minimum needed by naming askBeforePause and watchConfigured as the return payload. The dangling soclo:// URI is not a substitute for describing the return shape, which keeps it from a 5.

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?

Zero parameters, so there is nothing for the schema to document and no compensation is needed. The description instead spends its space naming the returned fields, which is a reasonable substitute.

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 (read) and resource (the askBeforePause / ask-first preference), and explicitly separates 'saved configuration exists' (watchConfigured) from the preference value itself. It does not fully disambiguate against the whole family of soclo_ads_watch_* siblings, but the naming and phrasing leave little doubt about what it returns.

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 routes the agent elsewhere for service status ('Use soclo_ads_watch_read for service status'), which is the nearest confusion point. It lacks an explicit statement of when this tool is the right call (e.g., 'call before pausing to check user preference'), but the context is clear enough.

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