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

With no annotations provided, the description carries the full behavioral burden. It discloses the authorization requirement (Bearer token) and the consequence that contribution points go to the claiming identity. However, it does not detail potential side effects, idempotency, or what happens on failure, leaving some behavioral aspects opaque.

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 exceptionally concise: two sentences, front-loaded with the core purpose, and includes the authorization note as a secondary but relevant detail. There is no redundancy or filler, making it highly efficient.

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 submission tool with two flat parameters and no output schema, the description covers the essential purpose and authorization. However, it omits details like expected response format, error conditions, or whether the submission is idempotent. Given the lack of annotations, a bit more context could be expected, but it is minimally complete.

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% (both 'body' and 'task_id' have descriptions). The tool description adds no extra parameter-level detail, so it does not enhance the schema semantics. Baseline of 3 applies because the schema already documents the parameters adequately.

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 ('deliver') and a resource ('result of a task you claimed yourself'), which clearly indicates the action. It implicitly distinguishes from siblings like 'claim_habitat_task' by focusing on submission of a completed task. However, it does not explicitly name any sibling tools, so it stops short of full 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?

The description conveys the prerequisite ('task you claimed yourself') and imposes an authorization requirement. It implies this tool is appropriate only after claiming a task, but it does not explicitly state when not to use it or mention alternative tools like 'claim_habitat_task' or 'post_habitat_task'. The guidance is adequate but not fully explicit.

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