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

Annotations only indicate non-read-only, non-idempotent, and non-destructive behavior. The description goes much further by disclosing the preflight check, the hard-block error type, the exact missing-field triggers, and the required follow-up flow with the user.

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 first sentence is a crisp, front-loaded action statement, and the following paragraph is dense but purposeful. Minor repetition exists around next_tool/getsign_update_workflow_settings, but every sentence earns its place.

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 covers the main failure mode, the required follow-up action, and the constrained use of skip_preflight, giving an agent enough to invoke the tool safely. It does not describe the success return payload, but the tool name makes the primary result inferable, and the missing sibling contrast is a minor gap.

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 only 25% (confirm_token only). The description adds useful semantics for skip_preflight, but item_id and envelope_id are left to inference, and confirm_token gains nothing beyond its schema description. It partially compensates for the low coverage but not fully.

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 and resource: generate a shareable signing link for a workflow item. The added preflight/error details make it clearly distinguishable from siblings like getsign_send_signature_request and getsign_get_document_url.

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 description gives explicit guidance on when to pass skip_preflight=true and what to do when the shareAndTrack config is missing, including the next tool to call. It does not explicitly contrast against sibling tools, but the invocation conditions are unambiguous.

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