outlook_download_task_attachment

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

Annotations declare the safety profile (readOnlyHint=false, idempotentHint=true, destructiveHint=false); the description goes beyond them usefully by disclosing that save_path is sandboxed to the configured attachments directory, that the write is atomic (temp file + replace), and that a failed download never truncates an already-staged file. Auth requirements and error/return behavior are not covered, but for a download tool this is unusually informative.

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 sentences, front-loaded with the core action, and the follow-up sentence is dense with non-redundant operational detail rather than filler. Nothing reads as padding.

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?

No output schema exists, so the description needn't explain returns, and the safety profile is annotation-covered. It communicates the destination semantics and failure behavior well; only permissions/error semantics are unaddressed, which is minor here.

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 0%, so the description carries the burden, yet it only adds meaning for save_path (resolves inside the configured attachments directory). The roles of task_id, attachment_id, and list_id are left entirely to the schema names.

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 a specific verb (Download) and resource (a To Do task attachment's content) with a clear destination (a local file). The qualifier 'To Do task' distinguishes it from the sibling outlook_download_attachment, which handles message attachments.

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 purpose implies the usage context, but there is no explicit when-to-use guidance or routing advice against the very similar sibling outlook_download_attachment. No prerequisites or preconditions (e.g., listing attachments first) are stated.

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