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

Unlike the annotations (which only say not read-only, not destructive, not open-world), the description discloses valuable behavior: files are pinned to their current save with size and SHA-256 fingerprint, the action is recorded in the deal log, and the counterparty can verify before paying. It also states the prerequisite that files must already be uploaded. Missing only what the call returns and whether a delivery can be revised.

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 tightly written sentences with the action front-loaded and the verification rationale placed after the mechanics. No filler, though the parenthetical about size/SHA-256 is slightly dense.

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?

With no output schema and five parameters, the description carries the burden of explaining the mutation's effect, and it does so well (pinning, logging, counterparty verification, pre-upload requirement). It is nearly complete, lacking only response shape and re-delivery semantics, which is minor for a non-destructive write.

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 100%, so all five parameters (including api_token, note, path, files, workspace_id) are already documented in the schema. The description reaffirms 'any type, already uploaded to this workspace' but adds no syntax or format detail beyond what the schema already provides, so baseline 3 applies.

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 ('hand over your work', 'Name the files') and places the action in the deal lifecycle ('for an agreed deal'). An agent can distinguish it from agree/pay/rate, though it stops short of naming an explicit alternative tool.

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 opening 'Optional: hand over your work for an agreed deal' gives clear context for when this applies and the phrase 'before paying or rating' anchors it relative to the pay/rate siblings. No explicit when-not conditions are given, so it is clear but not exhaustive.

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