remove_timer

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

Description adds useful context beyond annotations: 'Timers are renumbered after removal' and reaffirms destructiveness. Annotations already cover destructiveness and idempotency.

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?

Four concise sentences with no wasted words. Main action and key usage notes are front-loaded.

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?

For a simple tool with one param and no output schema, description covers action, prerequisite, renumbering behavior, and destructiveness. Could mention error handling for invalid index.

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?

Parameter 'index' is only described as the position from list_timers but lacks specifics on indexing (0-based vs 1-based) or valid range. With 0% schema coverage, description insufficiently compensates.

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?

Description clearly states 'Remove a timer task by index.' with specific verb and resource. Distinguishes from siblings like add_timer and list_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?

Explicitly advises 'Use list_timers to get current indices.' and warns about renumbering after removal, guiding proper usage sequence and caution.

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