timers_operate_all

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states the action without noting consequences (e.g., resetting timers may lose progress), authorization requirements, or whether it fails gracefully if some timers are already in the target state. This is insufficient.

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 a single efficient sentence that front-loads the core purpose. It wastes no words, but could benefit from additional context while remaining concise.

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?

Given no output schema, no annotations, and a simple parameter, the description is incomplete. It lacks details on return values, side effects, prerequisites (e.g., timers must exist), and error handling, which are important for safe invocation.

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 coverage is 100%, with the parameter 'operation' fully described via enum. The description adds no further meaning beyond the schema, so baseline score 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?

The description 'perform an operation on all timers simultaneously' uses a specific verb ('perform'), identifies the resource ('all timers'), and clarifies scope ('simultaneously'). This clearly distinguishes it from sibling tools like timers_start, timers_stop, which act on individual timers.

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 implies usage for bulk operations but does not explicitly state when to use versus alternatives (e.g., timers_start for a single timer). No exclusions or comparative guidance is provided, leaving the agent to infer context from sibling tool names.

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