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

No annotations are supplied, so the description carries the full behavioral burden. It usefully discloses returned data (status, per-attempt time, HTTP status or error), but does not state read-only safety, error behavior for unknown task IDs, rate limits, or whether delivery attempts are paginated or truncated.

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?

It is a single front-loaded sentence with zero wasted wording. The parenthetical efficiently clarifies what a delivery attempt contains.

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 one-parameter retrieval tool with no output schema, the description adequately explains the return contents. It is slightly incomplete around failure cases and pagination, but nothing critical is missing for typical invocation.

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 coverage is 100%: the single task_id parameter is fully documented with its pattern and origin from schedule_http. The description adds no parameter meaning beyond what the schema already provides, so the baseline of 3 applies.

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 and resource ('Get a task') plus the returned scope ('status and every delivery attempt'), which is clear and actionable. It does not explicitly distinguish itself from siblings such as list_tasks or watch_http, so it falls short of a 5.

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?

Usage is only implied: retrieve details for a single task. The description gives no explicit when-to-use guidance, no exclusions, and no alternatives such as list_tasks for enumeration or redrive_task for retries.

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