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

Annotations already declare this is a non-destructive, idempotent, closed-world mutation, so the safety profile is covered. The description usefully adds the effect—restoring ranking position on the brand page rather than creating a new boost—which is not in the annotations. However it stays silent on cost/credits, cooldowns, limits on how often a code can be refreshed, or what happens when the code is already at the top, all of which matter for a ranking-affecting write.

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?

One short sentence with the action front-loaded and no filler. It is efficient, though the brevity comes partly at the cost of the missing guidance noted elsewhere.

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?

With no output schema and a crowded sibling set (boost_code, refresh_all_codes, publish_code), the definition should say what the operation returns or what distinguishes it from boost_code. Neither is present, so it is not complete enough for confident selection.

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 coverage is 100% and the single parameter's description already tells the agent to source code_id from list_my_codes. The description adds no syntax, format, or constraint detail beyond the schema, so the baseline 3 applies.

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 sentence names a verb ("bump ... back up") and a resource (a code) and scopes the effect to the brand page ranking, which is concrete. But "bump back up" is vague about the actual mechanism, and it gives no signal distinguishing it from the sibling boost_code, which reads as an almost identical operation—nor from refresh_all_codes. An agent must guess which of the three to call.

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 statement of when to use this rather than boost_code or refresh_all_codes, no prerequisites, and no exclusions. The only usage hint comes indirectly from the code_id schema note pointing at list_my_codes.

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