memvid_create

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

Annotations cover basic traits (non-readOnly, non-destructive, etc.), but the description adds minimal context beyond 'create a new file.' It doesn't disclose details like file creation constraints, error conditions, or interactions with existing files, offering limited behavioral insight.

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, direct sentence with no wasted words. It's front-loaded and efficiently conveys the core action, making it highly concise and well-structured.

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 simple input schema (1 parameter) and annotations covering safety traits, the description is adequate but incomplete. It lacks output details (no output schema) and doesn't address file format specifics or error handling, leaving gaps in 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?

Schema description coverage is 100%, with the parameter 'file' documented as 'Path to the .mv2 memory file.' The description doesn't add extra meaning beyond this, so it meets the baseline for high schema coverage without compensating further.

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 verb ('Create') and resource ('new .mv2 memory file'), making the purpose unambiguous. However, it doesn't differentiate from sibling tools like 'memvid_put' or 'memvid_put_many' which might also create files, missing explicit distinction.

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?

No guidance is provided on when to use this tool versus alternatives. The description lacks context about prerequisites, file overwriting behavior, or comparisons to sibling tools, leaving usage unclear.

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