groups_multi_purpose_labels_get_one

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

With no annotations, the description carries the full behavioral burden. It does signal 'read-only', but says nothing about authentication requirements, permissions, error behavior when item_id does not exist, or whether the label is group-scoped. This is thin for a tool with zero structured annotation coverage.

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 useful content is the first two sentences; the remaining bulk is a ~20-term keyword list that restates the same verbs and nouns repeatedly. Only the endpoint line earns its place beyond the opening.

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 parameterized lookup with no output schema and no annotations, the description should explain what a 'multi purpose label' is in this API and what the response contains. It leaves both unspecified, so an agent cannot fully predict behavior before calling.

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 0% and the description adds nothing about item_id beyond the URL template placeholder. The schema's uuid4 format is the only hint; the description does not say the ID must be an existing group multi-purpose label's UUID or what happens otherwise.

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+resource ('Get label') scoped to Groups: Multi Purpose Labels, plus the concrete endpoint GET /api/groups/labels/{item_id}. It does not explicitly contrast with the sibling get_all/create_one/update_one/delete_one label tools, but the singular resource and ID path make the retrieval intent unambiguous.

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?

Nothing states when to use this versus groups_multi_purpose_labels_get_all or the other label siblings. The keyword list ('get label, fetch label, read label...') is a synonym dump, not usage guidance, and provides no conditions or exclusions.

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