card_label_remove

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

No annotations are provided, so the description carries the full behavioral burden and does not meet it. It never says whether the operation is idempotent when the label isn't on the card, whether it mutates only that card's associations, what permission level is required, or what is returned on success or failure.

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 front-loaded sentence with no filler; the trigger condition comes first and the identifier note follows. It is efficient, though so brief that it borders on under-specification rather than tight scoping.

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 simple two-parameter mutation with a fully documented schema and no output schema, this is close to adequate. However, with zero annotations the description should still cover idempotency and error behavior, and it does neither.

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% for both parameters, so the schema already documents that cardId accepts an id, short link, or URL. The description only echoes 'by label id' without adding format, constraint, or edge-case detail beyond the schema, which is the expected baseline of 3.

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?

The description names a specific verb and resource ('removing an existing Trello label from a card') and constrains the identifier ('by label id'). It implicitly separates itself from label_delete (removes the label from the board entirely) by scoping the action 'from a card', but never names the 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?

'Use when removing an existing Trello label from a card' gives a usable trigger condition, but offers no when-not guidance and does not distinguish this from card_label_add, card_label_create_and_add, or label_delete. An agent has to infer which of the four label tools applies.

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