initialize_agent

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

No annotations are provided, so the description carries full burden. It discloses that the tool launches a terminal CLI and requires Owner/Admin role. However, it does not mention side effects, reversibility, or potential environment requirements. More behavioral context would be beneficial.

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 well-structured with a clear one-line summary, detail paragraph, and formatted Args list. It is front-loaded. Minor redundancy: the first two sentences convey similar information.

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 description covers purpose, constraints, parameters, and return structure (including key fields). Given moderate complexity and output schema presence, it is fairly complete. Could add error scenarios or more explicit prerequisites.

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 input schema has no descriptions (0% coverage), but the description's Args block fully explains each parameter's purpose, valid values, defaults, and dependencies (e.g., custom_prompt only relevant for custom/file types). This adds significant meaning beyond the schema.

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 clearly states the tool initializes an agent and launches AI CLI with a role template. It mentions the prerequisite (agent created with create_agent) and the action. However, it does not explicitly differentiate from sibling tools like create_agent or terminate_agent, though the purpose is distinct.

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 provides usage context: only Owner and Admin can use, and it details prompt_type options (auto, custom, file). It implies usage after create_agent but does not explicitly state when not to use this tool or compare with alternatives. No exclusion criteria.

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