Claim a task

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

With no annotations available, the description carries the behavioral burden and does a good job: it discloses the recentActivityNearby return value, explains it contains real recent commits from others, and explicitly notes that a non-empty list does not block the claim. It could go further on persistence, permissions, or side effects, but the core behavior is clearly communicated.

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?

Three sentences, each earning its place: purpose first, then the key return value, then the important caveat about non-blocking behavior. No wasted words and the most decision-relevant information is front-loaded.

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 no annotations, no output schema, and minimal input schema, the description is fairly complete for a simple claim action. It explains purpose, source of the task, what the return contains, and how to interpret it. The main missing piece is parameter semantics, particularly memberName, and clearer routing against sibling tools.

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%, and the description adds little parameter-level meaning. It implies taskId comes from get_context, but never explicitly names or explains taskId, and memberName is entirely absent from the description. This is a meaningful gap for two parameters.

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 uses a specific verb ('claim') and resource ('existing task'), and clearly states the purpose: signaling to teammates that you're working on it. It also points to get_context as a source of the task, helping differentiate from creation-oriented siblings like declare_task.

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 the usage context: after getting a task from get_context and before diving in. However, it never explicitly states when not to use this tool or names alternatives like declare_task, update_task_status, or log_activity, so the agent must infer the boundary between these siblings.

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