penpot_create_file_snapshot

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

With no annotations, description carries full burden. It explains creation, return of metadata including id, and constraints on later operations. However, it doesn't disclose potential side effects like file modification dates or authorization 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?

Two sentences efficiently convey purpose, parameter details, and a behavioral note. No fluff; every sentence adds value.

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 create tool with 2 params and no output schema, description covers purpose, parameter behavior, and return value. Lacks mention of prerequisites or rate limits, but sufficient for typical use.

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 has 0% description coverage. Description adds meaning: fileId is required, label is optional with auto-generated timestamp; also explains consequences of omitting label. Significantly augments schema.

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?

Description clearly states verb (create), resource (snapshot of a file), and purpose, and distinguishes from siblings like get_file_snapshot and delete_file_snapshot.

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?

Explains optional label and auto-generation behavior, and notes that only user-created snapshots can be renamed/deleted/locked. Lacks explicit when-not-to-use or alternatives, but provides clear context for usage decisions.

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