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

The description clearly warns that sync_task_templates overwrites and deletes omitted templates, that relationship collections replace full lists, and that pricing/recurrence changes affect future delivery. This goes beyond the destructiveHint annotation by specifying exactly which operations are destructive and how to avoid unintended deletions.

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?

The main description is front-loaded with key warnings, and parameter descriptions are dense but relevant. The overall length is justified by 28 parameters, with minimal fluff, though a few descriptions restate information already implied by the parameter name or type.

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?

The description covers conditional fields, required-vs-optional behavior for create and update, destructive semantics, unit conversions, and relationship replacement rules. Even without an output schema, an agent has enough context to invoke the tool correctly and avoid common mistakes.

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?

Every parameter is described, and many descriptions add crucial semantics not inferable from the schema alone, such as deadline being in hours, recurring enum meanings, conditional requirements for recurring=2, folder_id null-versus-omitted behavior, and the full-replacement behavior of task_templates. This far exceeds the baseline expected from full schema coverage.

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 explicitly states that the tool creates or updates services and syncs task templates, clearly identifying the resource and actions. It also distinguishes itself from read-oriented tools by instructing the agent to fetch task templates before syncing, making selection unambiguous.

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?

The description gives concrete usage rules: call get_task_templates before sync_task_templates and retain IDs to avoid deletion, convert deadlines to hours, and understand that relationship collections replace full lists. It could more explicitly contrast with service-read for ordinary reads, but the write-versus-read distinction is clear enough.

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