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

Annotations already show this is a write (readOnly=false) and non-destructive (destructive=false). The description adds meaningful behavioral context beyond annotations by explaining that the capsule is signed and sanitized, and that the continuity ledger stores only hashes and transition metadata, not task text.

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 concise sentences with no wasted words. The action and resource are front-loaded, and the second sentence adds valuable storage/security context without padding.

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?

Given the tool has 7 parameters, no output schema, and a set of closely related siblings, the description is not complete enough. It leaves the agent unsure when to use this tool versus handoff_agent_task, what output to expect, and how to shape the optional fields.

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 provides no parameter-level guidance. With 7 parameters and only goal required, the agent receives no explanation of how completed, remaining, nextAction, constraints, verifiedFacts, or requiredCapabilities should be populated. The description entirely fails to compensate for the empty schema descriptions.

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?

States a specific action ('Create') and resource ('signed sanitized cross-agent task capsule'). The description makes the core purpose understandable, but it does not explicitly distinguish this from sibling tools like handoff_agent_task, so it falls just short of full differentiation.

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 when-to-use guidance is provided. The description never mentions alternatives such as handoff_agent_task or verify_handoff_capsule, nor does it give conditions, exclusions, or prerequisites. An agent must infer when this tool is the correct choice.

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