all the tools

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

With no annotations provided, the description carries the full burden and adds valuable behavioral context beyond the input schema. It discloses that deletion is destructive (implied by 'Deletes'), mentions cascade effects ('deletes its subtasks and dependency links'), and specifies the return value ('count of successfully deleted tasks'). However, it lacks details on permissions, error handling, or rate limits.

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 front-loaded with the core purpose, followed by parameter requirements, important behavioral notes, and return information—all in four concise sentences with zero wasted words. Each sentence earns its place by adding distinct value.

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 the tool's complexity (destructive operation with cascade effects), no annotations, and no output schema, the description does well by explaining the action, parameters, cascade behavior, and return value. However, it could be more complete by addressing error scenarios or prerequisites (e.g., authentication needs), which are missing.

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?

The schema description coverage is 100%, so the schema already fully documents the parameters (project_id and task_ids). The description adds minimal semantic value by restating the need for 'project ID and an array of task IDs' but does not provide additional context like format examples or edge cases beyond what the schema describes.

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 clearly states the specific action ('Deletes'), the resource ('one or more tasks within a specified project'), and distinguishes it from siblings like 'deleteProject' (which deletes entire projects) and 'listTasks' (which only reads). It provides a precise verb+resource combination that differentiates its scope.

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 context by specifying 'within a specified project' and listing required parameters, but it does not explicitly state when to use this tool versus alternatives like 'deleteProject' or 'setTaskStatus' (which might archive instead of delete). No explicit exclusions or comparison to siblings are provided, leaving some ambiguity.

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