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

No annotations are provided, so the description carries the full behavioral burden. It does not disclose whether the tool blocks execution, merely validates, is read-only, or what it returns; the '0.002 USDC' cost hint is the only behavioral detail, and it is terse.

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 compact sentence front-loads the core action and includes the cost. It is efficient, though the compression is part of what leaves the contract underspecified.

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 three-required-parameter, nested-object tool with no annotations and 0% schema coverage, the description is far too thin. Even noting that an output schema exists, the input contract and the guard's effect are not conveyed, so the definition is not sufficient to call 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 description coverage is 0% and all three parameters are untyped nested objects ('call', 'intent', 'policy'). The description names the concepts but adds no structure, expected shape, or required fields for any of them, so the agent must guess the object contracts.

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 specific verb ('Bind') and objects ('proposed tool call', 'declared intent', 'execution policy'), which is more specific than the name alone. However, 'Bind' is abstract jargon and the tool's actual effect (validation? logging? blocking?) is left ambiguous, so an agent cannot fully distinguish it from siblings like delegation_scope_guard or preflight.

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 given. With sibling tools such as preflight, payment_preflight, mcp_manifest_firewall and delegation_scope_guard all plausibly overlapping with policy enforcement, the agent has no signal about which guard to invoke in which scenario.

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