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

Annotations already declare non-destructive, idempotent, closed-world write semantics, so the bar is lower; the description still adds real value by clarifying the operation only stages a packet and does not submit, prove delivery, or purchase coverage, plus a 'no secrets or credential uploads' constraint. It stops short of saying what is returned or whether the saved task is editable afterward.

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 compact sentences with the core action front-loaded and every clause carrying information — scope, staging-only behavior, and the credential prohibition. No filler or restated title.

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 mutation tool with a nested 12-property object, no output schema, and 5 parameters, the description leaves the answers payload completely unexplained and never says what the caller gets back (task id? status?). The safety framing is good, but an agent cannot construct a valid call from this plus the schema alone.

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 20% — just idempotency_key — and the nested 'answers' object has twelve undocumented sub-fields (usecases, privacy_url, material_ids, etc.). The description's mention of 'field packet' and 'eligible package' vaguely gestures at answers and material_ids but explains none of the field meanings or which are required per channel.

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 action and object ('Saves a field packet and eligible package') and scopes it to 'Claude/OpenAI owner review' preparation. 'Never submits, proves delivery or adds paid coverage' implicitly separates it from authorize_publisher_task, though that sibling is not named.

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 phrase 'Free preparation for Claude/OpenAI owner review' implies the phase in which to call it, and 'never submits' implies a later authorize step exists. But no alternative tool is named and no explicit when-not guidance is given beyond the negation of submission.

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