agent_manage

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

With no annotations, the description carries the full burden. It does not disclose whether re-registering overwrites prior state, what permissions are required, whether presence is ephemeral or persisted, or how the three operations differ behaviorally. Only 'shared project' adds any context beyond the name.

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 no padding, so it is concise. But it is under-specified rather than tight, omitting one of the three operation modes, so conciseness comes at the cost of usefulness.

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?

The tool has 7 params, no annotations, no output schema, and 0% schema coverage, yet the description addresses none of the parameter or behavioral details. For a multi-operation management tool it is materially incomplete.

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?

Seven parameters with 0% schema description coverage, and the description explains none of them. Fields like name, role, capabilities, runtime, and agentId are entirely undocumented, and the description does not clarify how operation values map to which other parameters are required.

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 names a verb pair (Register/update) and resource (agent runtime / presence in shared project), which gives a usable sense of purpose. However, the operation enum exposes three modes (register, status, list) and the description only accounts for two, leaving the 'list' capability unexplained. It also does not differentiate this tool from siblings like agent_message or task_manage.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no pointer to an alternative tool. The phrase 'shared project' hints at scope but the agent is left to infer when registration or presence updates are appropriate versus messaging or task tools.

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