apex_finalize_app

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

Annotations already indicate this is not read-only (readOnlyHint false) but also not destructive (destructiveHint false). The description adds the sequencing requirement but does not disclose whether finalization is reversible, what side effects occur, or what happens if called prematurely. There is an apex_undo_last sibling, but the description doesn't address undoability. So some transparency but gaps.

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 a single sentence, front-loaded with the action, and includes only necessary contextual information ('Must be called after...'). No filler or redundancy.

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 zero-parameter tool with an output schema, the description covers the essential purpose and timing. It could elaborate on the finalization process and any irreversible effects, but given the simplicity and output schema presence, it is reasonably complete.

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?

The input schema has zero parameters, making schema coverage 100%. The description correctly adds no parameter information since there are none. Per baseline for 0 parameters, the score is 4.

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 the action ('Finalize and commit the app') and the resource. It also notes the required ordering relative to adding pages/components, helping distinguish it from other app-level operations like apex_commit_batch or apex_dry_run_preview. Slightly vague on what 'finalize' entails, but the intent is clear.

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?

Explicitly states 'Must be called after all pages/components are added,' providing a clear precondition and timing guideline. It implies this is the final step, which distinguishes it from preview/validate tools. Does not mention alternative tools or exclusions, but the guidance is sufficient.

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