start_workspace_session

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

With no annotations, the description must disclose behavioral traits. It only states 'Creates workspace + session,' implying mutation, but does not mention permissions, rate limits, or details about the coding agent launch (e.g., asynchronous behavior).

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?

Description is structured with usecase, parameters, and example sections. It front-loads the main purpose, but the usecase and parameters tags are somewhat redundant with the plain text. Overall 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?

Covers basic purpose and parameters, but lacks information about return values, side effects, or prerequisites (e.g., task must exist). Given no output schema and no annotations, more context would be helpful for an agent to use correctly.

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 coverage is 100%, so description adds little beyond the schema. It provides an example call and restates parameter lists and defaults, but the schema already includes descriptions and defaults. The example is the main added value.

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?

Clear verb ('Start') and resource ('coding session for a task'). The usecase tag further clarifies it launches a coding agent and creates workspace+session, distinguishing it from siblings like create_task (creates task only) or get_session (retrieves existing).

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?

No explicit guidance on when to use this tool versus alternatives. While the description implies it's for launching a coding session, it doesn't specify prerequisites (e.g., task must exist) or when to use list_sessions or get_session instead.

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