kaiten_delete_user_timer

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

With no annotations provided, the description carries the full burden of behavioral disclosure, and 'Delete a user timer' only conveys that the operation is destructive. It reveals nothing about reversibility, side effects on related data, permission requirements, error behavior for non-existent timers, or 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?

The single sentence is maximally concise and front-loaded with the action. However, it borders on under-specification rather than deliberate conciseness, since several behavioral dimensions are entirely unaddressed. It earns its place but there is simply too little of it.

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 destructive tool with no annotations and no output schema, the description is incomplete: it doesn't state what happens on success or failure, whether deletion is reversible, or whether timer_id can be obtained from kaiten_list_user_timers / kaiten_get_user_timer. A simple tool lowers the bar slightly, but a delete operation still needs more than a bare verb+object phrase.

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%, so the baseline is 3. The description adds nothing beyond the schema ('timer_id' / 'Timer ID', which is itself largely tautological), and it doesn't hint at how to discover a valid timer_id (e.g., via kaiten_list_user_timers). The high coverage keeps this at baseline rather than lower.

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 states a specific verb ('Delete') and resource ('user timer'), clearly distinguishing it from the create/get/update/list user timer siblings. However, it doesn't explain what a 'user timer' is, which matters given the presence of the seemingly adjacent kaiten_delete_time_log, and it relies entirely on the verb for differentiation.

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?

No guidance is given on when to use this tool versus alternatives such as kaiten_delete_time_log, kaiten_delete_sprint, or other delete_* tools. There are no prerequisites, no context about timer state, and no mention of how this differs from the ~40 other delete operations in the sibling list.

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