modal_app_rollover

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

No annotations are provided, so the description carries the full burden. It only states the intended outcome without disclosing behavioral traits such as whether the app is stopped, whether downtime occurs, how the strategy parameter affects the rollout, or any permissions required. This is insufficient for a mutating operational tool.

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, focused sentence that conveys the core functionality with no redundant words. It is front-loaded and easy to parse.

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?

The description covers the essential purpose but lacks details about the rollover process, the meaning of the strategy enum, or the expected outcome. For a tool with no output schema and no annotations, it could provide more context to fully inform the agent about what happens when invoked.

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% with descriptions for all three parameters, so the baseline is 3. The description does not add parameter-specific details, but the overall purpose helps contextualize appIdentifier and strategy. No additional meaning is provided beyond what the schema already contains.

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 clearly states a specific action ('Redeploy an App') and its purpose ('get new containers without code changes'), distinguishing it from sibling tools like modal_deploy (which involves code changes) and modal_app_rollback (which reverts to a previous version). The scope is 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?

The phrase 'without code changes' provides clear context for when to use this tool versus alternatives, implying it is for operational refreshes rather than code deploys. However, it does not explicitly name alternative tools or state exclusions, so it falls short of full guidance.

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