deleteStickerFromSet

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly communicates the destructive action ('Delete') and the 'created by the bot' precondition, and it states the success return value. However, it does not mention irreversibility, failure behavior, or any permissions needed, though for a simple delete operation this is a moderate gap.

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 description is one concise sentence that front-loads the action and resource, then gives the return behavior. Every word earns its place, with no filler or repetition.

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 one-parameter tool with no output schema, the description is complete: it names the operation, restricts it to bot-created sets, and states the return value. The schema covers the parameter fully, and the sibling list does not reveal any missing edge case that would prevent an agent from invoking this correctly.

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%, and the sole parameter 'sticker' is already documented as 'File identifier of the sticker.' The description adds no additional parameter meaning beyond what the schema provides, so the baseline of 3 is appropriate.

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 uses a specific verb ('Delete') and states the exact resource: a sticker within a set created by the bot. It also distinguishes itself from sibling tools like deleteStickerSet by clarifying it removes a single sticker, not the entire set.

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 description implies the usage context: use this when you need to remove one sticker from a bot-created sticker set. However, it does not explicitly contrast with alternatives such as deleteStickerSet, replaceStickerInSet, or setStickerPositionInSet, leaving selection partly to inference.

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