tascan_delete_subtask

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

The description adds that the deletion cascades to completions and is irreversible, which is valuable beyond the annotations' destructiveHint and idempotentHint. It does not contradict the provided annotations and gives clear context about what gets destroyed.

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?

Two short, direct sentences contain all essential information. The primary action is front-loaded and the irreversibility warning is immediate, with no unnecessary content.

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 destructive operation with one clearly documented parameter, the description sufficiently covers the object being deleted, the cascading effect, and permanence. It does not describe return values, but there is no output schema and the tool's purpose is straightforward.

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?

With 100% schema description coverage, the schema already fully describes the single 'subtask_id' parameter. The description does not add parameter-level details, but none are needed given the schema's clarity.

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?

States the specific action 'Delete a subtask and its completions' with a clear verb and resource, and explicitly notes the irreversible nature. It clearly distinguishes itself from sibing delete_task by targeting subtasks and their associated completions.

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 explicit guidance on when to use this tool instead of alternatives such as tascan_update_subtask or tascan_complete_subtask. The resource name implies the usage, but the description does not state conditions, exclusions, or alternative selection criteria.

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