Bump a JsonFabrica sequence

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

With no annotations, the description carries the behavioral disclosure burden. It clearly reveals that this is a POST/mutating operation, that it advances the sequence by its configured step, and that it returns the updated record. It does not mention authentication, idempotency, or irreversibility, but the core side effect is explicitly disclosed.

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?

Two short sentences contain the endpoint, the action, the sequencing behavior, and the return value. There is no filler, and the most identifying information is front-loaded.

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?

This is a simple tool with one required parameter and no output schema or annotations. The description covers what the tool does, how it does it via the endpoint, and what it returns. Minor gaps such as error behavior and prerequisite existence of the sequence prevent a perfect score, but the essential calling context is present.

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%, so the description must compensate. The path segment '/sequences/{name}/bump' indicates that 'name' is the sequence name, which is useful, but it does not explain what sequences are eligible, whether the name must already exist, or any formatting constraints. It adds some meaning beyond the bare schema but not complete parameter guidance.

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 ('bump'), a specific resource ('sequence'), and gives the exact HTTP endpoint. It also states the observable effect—advancing the sequence by its step and returning the updated record—making it clearly distinct from sibling operations like update_sequence or get_sequence.

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?

There is no guidance on when to use this tool versus alternatives such as update_sequence, get_sequence, or create_sequence. The action is described, but no context, prerequisites, or exclusions are provided, so an agent must infer when bumping is appropriate.

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