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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value beyond them by disclosing the shape of the returned data (tasks, resources, linked assets) and the important quirk that monetary amounts are bare numbers requiring a separate settings lookup.

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?

Two tight sentences: purpose first, then the currency caveat. Every sentence earns its place and the most actionable warning is not buried. Slightly better than average sizing with no filler.

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 available, the description carries the burden of describing the payload and does so at a summary level, plus flags a real formatting hazard. It omits error/not-found behavior and how to discover an ID, but for a one-parameter read tool it is largely complete.

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 100% and the single 'id' parameter is fully documented in the schema (type, UUID format, pattern). The description adds no additional semantics about the ID (e.g., where to obtain it), so the baseline of 3 applies.

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 and resource (get a PM schedule) and enumerates what the payload contains (tasks, resources, linked assets), which goes beyond a tautological restatement of the title. It does not explicitly distinguish itself from list_pm_schedules or get_compliance_pm_schedule, so an agent must infer the 'specific by ID vs. list' distinction from 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?

There is no explicit when-to-use/when-not-to-use guidance versus siblings such as list_pm_schedules or get_compliance_pm_schedule; usage is only implied by the required UUID parameter. It does, however, give one concrete cross-tool routing instruction (call get_organization_settings for currency_code), which is a partial usage rule.

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