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

With no annotations supplied, the description carries the full burden. It does add real operational context that structured fields cannot: the $0.01 USDC-on-Base cost, the x402 payment vehicle with the exact params._meta key, and the POST endpoint. It says nothing about failure modes, what happens when payment is missing, or the response shape, which leaves meaningful gaps for a paid mutation-free compute call.

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?

Front-loaded with the capability, then the two pieces of invocation-critical metadata (price/payment and endpoint) in tight succession. Dense but no wasted sentences; the payment string is unavoidably verbose.

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?

No output schema exists and the sole input is an undocumented array of objects with three nested fields, so the description should have explained what a task entry looks like and what a result contains. It covers cost and transport well but leaves the actual data contract entirely to inference.

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?

There is one top-level parameter with 0% schema description coverage, and the description never mentions it. The enumerated outputs (weekdays, business days) hint that the nested 'unit' and 'start' fields select calendar conventions, but the meaning of 'days', valid 'unit' values, and the date format for 'start' are entirely undocumented.

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?

States a specific verb and resource ('Plan a whole task list at once') and enumerates the outputs it produces (due dates, weekdays, business days remaining, overdue flags). It is clearly a batch deadline-calculation tool, though it never contrasts itself with near-neighbours like agentkit__sla or bizcal_api__workdays.

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 'a whole task list at once' implies the batch-vs-single distinction, which is some usage guidance. However, no alternative tool is named, no preconditions are stated, and nothing tells the agent when this is the wrong choice versus the many calendar/SLA siblings.

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