orchestrate_init

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only mentions 'HMAC anti-tamper security' and gives no details about what initialization does, what side effects occur, whether an existing session must be absent, or what happens on failure. This is thin disclosure for a state-creating operation.

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 one clean front-loaded sentence with no wasted words. It is concise and scannable, though the brevity comes at the cost of missing useful usage and semantic guidance.

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 output schema does carry return-shape information, and the two parameters are simple, so the tool is minimally callable. However, the description does not explain the orchestration setup context, how workspace_root should be used, or how this tool fits in the orchestration lifecycle among six 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 does not explain either task_description or workspace_root. The parameter names are somewhat self-explanatory, but the tool description itself contributes no meaning, and with a nullable workspace_root, the intended semantics and null behavior remain ambiguous.

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 phrase 'Initialize a new orchestration session' gives a specific verb and resource and clearly distinguishes it from lifecycle siblings like orchestrate_status and orchestrate_archive. The HMAC clause is a security qualifier rather than a purpose statement, so it does not help define intent.

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 word 'Initialize' and the qualifier 'new' imply when this should be used, but the description does not explicitly state when to use it versus alternatives, does not mention lifecycle ordering, and provides no exclusions or prerequisites. Absence of explicit routing leaves some interpretation to the agent.

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