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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered; the description adds useful auth context ('ChannelOAuthId resolved internally', 'send exact payload in body') and clarifies it is a fixed endpoint, not a generic caller. It does not disclose what the operation actually loads or any side effects, so with annotations doing the heavy lifting a 3 is right.

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 endpoint identification is front-loaded, but the text is puffed with doc-template boilerplate ('This is an explicit tool with a fixed endpoint; it is not a generic endpoint caller', 'Search terms: sales loadprogress') and repeats the same 'load progress operation for sales/order operations' phrasing three times.

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?

An output schema exists so return values needn't be explained, and auth handling is stated. However, for a POST endpoint with an opaque body the description leaves a key gap: what 'load progress' actually does and how it differs from the sibling hgr_load_order_progress.

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 coverage is 100% for the two parameters, so the baseline is 3. The description only adds that LoadProgressRequest's main field is 'Id: int', which is thin detail about an otherwise opaque body object, and offers no syntax or constraints beyond the schema.

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?

It names the verb+endpoint ('POST api/Sales/LoadProgress') but 'load progress operation' restates the tool name rather than explaining what it actually does with sales/order data. It also never distinguishes itself from the sibling hgr_load_order_progress, which an agent would find nearly indistinguishable.

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?

'Use it when: Use it when a client needs to run the load progress operation for sales/order operations' is circular and adds no condition for selection. No when-not guidance and no mention of the similar hgr_load_order_progress or other hgr_post_sales_* siblings.

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