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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does add a key safety trait: 'Does not transmit customer data or execute business actions,' which tells the agent it is a non-destructive, privacy-preserving operation. However, it does not describe what happens to the bundle, whether it is stored, or any permissions required. The single behavioral note is useful but incomplete.

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 very concise, using only two short sentences. It front-loads the core purpose and then adds a behavioral caveat. No wasted words, but it could be more informative without sacrificing brevity. The structure is efficient, though slightly sparse.

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 4 parameters and no output schema or annotations, the description is severely incomplete. It does not explain what a 'handoff bundle' is, what each parameter does, what the output format is, or any context for when it is appropriate. The agent would have to guess at parameter semantics and tool behavior. This is far below the minimum viable level.

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 has 4 parameters (goal, problem, data_shape, constraints) with 0% description coverage, and the description provides no information about any of them. The agent has no guidance on what values to supply or their meaning. This is a critical gap that the description does not address at all.

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 states a clear, specific action: 'Prepare a privacy-preserving human handoff bundle.' It also differentiates from siblings by noting it 'Does not transmit customer data or execute business actions,' which distinguishes it from buildflow_discover_capabilities and buildflow_route_intent. The verb 'prepare' and resource 'handoff bundle' are unambiguous.

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 guidance on when to use this tool versus the siblings. The description does not mention any conditions, prerequisites, or alternatives. While the purpose implies a handoff scenario, it does not state when an agent should choose this over buildflow_route_intent or buildflow_discover_capabilities.

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