create_v2_delegation

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

No annotations are provided, so the description carries the full burden. It discloses that the delegation has mandatory sunset and PolicyContext binding, but does not explain prerequisites, side effects on existing delegations, or how versioning works. This is minimal behavioral transparency.

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?

A single sentence that is front-loaded and information-dense. Every phrase adds value: 'v2', 'versioning', 'mandatory sunset', and 'PolicyContext binding' are all meaningful discriminators.

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 gives a high-level overview but omits details about the return value, how PolicyContext binding is established (no corresponding parameter), and the implications of versioning. For a create operation with no output schema, more context is needed for full agent confidence.

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 75%, with trust_epoch undocumented. The description does not add meaning beyond the schema; 'versioning' might hint at trust_epoch's purpose but is not explicit. Since coverage is moderate, the description leaves a gap for trust_epoch.

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 creates a v2 delegation, distinguishing it from the sibling create_delegation (likely v1). The mention of versioning, mandatory sunset, and PolicyContext binding clarifies the specific resource and variant.

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 name and feature list imply when to use this tool (for v2 delegations with sunset and policy binding), but the description does not explicitly state when to prefer it over create_delegation or supersede_v2_delegation, nor does it mention exclusions.

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