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

Annotations already declare the tool destructive and idempotent. The description adds useful operational context beyond that: it requires explicit approval metadata and a matching idempotency key, and it operates on an already-previewed publish. It does not detail downstream side effects, but the destructiveHint covers the main risk.

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 a single tight sentence with no filler. It front-loads the action and immediately communicates the two key constraints: prior preview and approval metadata.

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?

This is a complex, nested-object mutation tool with no parameter descriptions and no output schema. The description explains neither where the approval metadata fields come from (presumably the preview response) nor what happens on mismatched idempotency keys or version preconditions. An agent would need substantial prior knowledge of the bind/preview protocol to invoke it 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%, so the description must compensate. It broadly groups the binding object as 'explicit approval metadata' and mentions a 'matching idempotency key,' but it does not explain the purpose of preview_hash, approved_input_hash, approved_action_key, or resource_version_precondition. An agent would still be guessing about how to populate the nested binding object correctly.

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'), a resource ('an already-previewed job-posting publish'), and the distinctive context of explicit approval metadata. It clearly distinguishes this bind step from the sibling publish_preview tool and the archive_bind pattern.

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?

'Already-previewed' clearly signals that this tool is used after a publish preview, and 'matching idempotency key' indicates a key precondition. It does not explicitly name the alternative (publish_preview) or state 'do not call without a preview,' but the context is strong enough for an agent to identify the intended flow.

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