v2.2.4Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate a write operation (readOnlyHint=false, destructiveHint=false), and the description adds useful behavior: entries are validated and calendar conflicts are checked before writing. It does not, however, explain atomicity, partial-failure behavior, or how conflictPolicy affects the outcome, so it adds only modest transparency beyond the annotations.
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 description is two short sentences with no filler. It front-loads the core action and scope, then adds a relevant safety guarantee. Every word earns its place.
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?
Despite the highly complex nested schema and no output schema, the description is too brief to be complete. It omits return behavior, error handling, meaning of conflictPolicy values, and how validation failures are surfaced. The mention of pre-write validation and conflict checking is useful but far from sufficient for this tool's complexity.
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 0%, and the description does not compensate by explaining key parameters such as date, steps, overview, or conflictPolicy. It only vaguely references validation and calendar conflicts, which is insufficient for such a nested and complex input schema.
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 uses a specific verb ('Create and schedule') with a clear resource ('structured running/cycling workouts') and an explicit batch scope ('several ... in one request'). This distinguishes it from sibling tools like create_structured_workout, which handles a single workout, and from scheduling-only tools.
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 phrase 'several ... in one request' gives a clear signal that this tool is for batch creation and scheduling, which helps an agent choose it over single-item alternatives. It does not explicitly name alternatives or state when not to use it, but the use case is reasonably clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
