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

No annotations are provided, so the description carries full burden. It discloses that it serializes all tracks, regions, effects, notes, settings to an ArrayBuffer and saves to exports directory. It also states the return values: file path, size, and box count. However, it does not specify overwrite behavior or permission requirements.

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 four sentences: purpose, serialization details, companion tool reference, and parameter/returns note. It is concise and front-loaded, with no unnecessary words.

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?

Given the tool's complexity (saving entire project), the description covers: what is serialized (boxGraph), output format (.odaw), location (exports directory), parameter detail (no extension), return values (path, size, box count), and complementary restore tool. Even with an output schema present, the description provides sufficient context.

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 only parameter 'filename' is described as 'Name for the saved project (without extension).' This adds crucial meaning beyond the schema, which only provides a title and type string. Since schema coverage is 0%, the description fully compensates.

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 'Save the current project state to a binary file.' It specifies the verb 'Save', the resource 'project state', and the format '.odaw file'. It also distinguishes itself from sibling tool 'load_project' by mentioning it as the complementary load operation.

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 description explains that it serializes the entire boxGraph and saves as .odaw file, and explicitly suggests using load_project to restore later. This gives clear when-to-use context and a sibling tool reference, but does not mention when not to use or alternatives like export_mix or export_stems.

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