proj_save

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

No annotations are provided, so the description must carry the behavioral burden. It never says what saving actually does: writes to disk, overwrites the file on disk, requires an open project, whether it prompts a dialog, whether it saves all documents in the project, or what happens on failure. Only the return type is disclosed.

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 purpose sentence is front-loaded and the Args/Returns sections are short and structured. The Returns line duplicates what the output schema already declares, so it is slightly redundant, but nothing is bloated.

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 mutation tool with zero annotation coverage, the description leaves out essential context: persistence/side-effect semantics, preconditions (project must be open), and behavior on unsaved or read-only state. The existence of an output schema excuses not explaining return values, but the rest of the behavior gap remains.

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 0%, so the description carries the parameter explanation, and it does add meaning beyond the schema's bare 'project_path' string: it says the value is an optional path to a specific project and that omitting it targets the active project. That default behavior is not inferable from the schema alone.

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 states a specific verb and resource ('Save the current or specified project'), which is clear enough for an agent to know this persists project state. It does not distinguish itself from close siblings like app_save_all or app_save_document, so the agent cannot tell whether this is project-wide or document-level save.

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 guidance on when to use this versus app_save_all, app_save_document, or app_checkpoint. The 'If None, saves active project' note is the only usage hint and it concerns parameter behavior, not tool selection.

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