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

No annotations are provided, so the description carries the behavioral disclosure burden. It explicitly discloses the side effect that the profile 'persists onto the agent,' and '(re)generate' implies overwriting or updating the existing profile. It does not mention cost or async behavior, but this is reasonable for a one-parameter mutation.

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 short sentences with no filler. The main action and the key persistence consequence are front-loaded, making the description easy to scan and act on.

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 tool with one parameter and no output schema, the description explains what happens, where the result is stored, and why it matters for later Signal Searches. It does not mention the return value or whether generation is asynchronous, but those details are secondary for this mutation-oriented tool.

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?

The schema provides only 'agent_id' as a required string with no description, and the description does not explicitly document the parameter. However, the tool text's repeated reference to 'the agent' plus the self-explanatory parameter name makes the intended meaning clear for this simple single-parameter tool.

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 specific action and resource: running Claude on the agent's knowledge to (re)generate its signal profile. It also explains the persistence behavior, which distinguishes this generator from sibling accessor tools like sdr_get_agent_signal_profile.

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 text clearly indicates when the tool is needed: to generate or regenerate an agent's signal profile so later Signal Searches can reuse it. It does not explicitly name alternatives or state when not to use it, but the context is clear enough for a single-purpose tool.

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