digikey_get_mylist

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that list-line data is returned alongside the list itself, which is modest but useful context about payload scope; it says nothing about permissions, rate limits, or whether the read is a live call to DigiKey.

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?

A single tight sentence with the operation front-loaded and no filler. It is efficient, though the extreme brevity is also what leaves the gaps in usage and parameter guidance.

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 need not be explained, and the annotations cover the safety profile. What remains missing is how list_id is obtained and how this read relates to the enumerate/validate/apply siblings — enough to make the definition only minimally sufficient.

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 required parameter (list_id) with 0% schema description coverage, and the description does not characterize it at all — no format hint, no statement that it comes from digikey_list_mylists. With a low-coverage schema the description should compensate and does not.

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 ('Read') and resource ('one DigiKey MyList') plus the payload ('its current list-line data'), which is clearer than a bare name restatement. It implicitly distinguishes the singular read from the sibling digikey_list_mylists (plural enumerate), though it never names that sibling explicitly.

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?

No when-to-use guidance is given: nothing says this is the fetch-one-list operation to use after enumerating lists or before mutating lines. Siblings like digikey_list_mylists, digikey_validate_mylist and digikey_preview_mylist_changes are not referenced, so the agent must infer the routing itself.

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