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

With no annotations, the description carries the full burden. It discloses the serialization process (boxGraph to ArrayBuffer), the output format (.odaw), the save location (exports directory), and return values (file path, size, box count). It does not mention potential overwrites or errors, but the provided details go well beyond a minimal description.

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 compact and well-organized: a main action sentence, a short technical explanation, a cross-reference to load_project, and explicit parameter/return notes. Every sentence earns its place with no fluff 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 simple tool with one parameter and no nested objects, the description is complete. It covers what the tool does, what data it serializes, where it saves, what the filename parameter means, and what it returns. The existence of an output schema further reduces the need to explain return structure in prose.

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 schema only lists 'filename' with type string and no description. The description adds crucial meaning: 'Name for the saved project (without extension).' This clarifies that the extension is added automatically, which is essential for correct usage. For a single-parameter tool, this fully compensates for the 0% schema coverage.

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 ('Save the current project state to a binary file'), specifies the resource (boxGraph with all tracks, regions, effects, notes, settings), and differentiates from siblings by mentioning the .odaw format and exports directory. It also explicitly references load_project, distinguishing it as the saving counterpart.

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?

Provides clear context: use this to persist the entire project for later restoration, and explicitly mentions 'Use load_project to restore later.' It does not enumerate exclusions or compare with other export tools, but the context is specific enough for an agent to choose it over alternatives like export_midi or export_mix.

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