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

No annotations are provided, but the description discloses key behavior: list is free, ordering is newest-first, and neither action returns checkpoint contents. This adds meaningful context beyond the schema, though it does not cover side effects of creation 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?

Three concise sentences cover purpose, usage advice, and a behavioral caveat with no redundancy. Information is front-loaded and the description is appropriately sized.

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?

The tool has an output schema and a moderate parameter count; the description covers the main workflows. It lacks detail on parameter meanings and restore mechanics, but overall is sufficient for basic usage.

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 description explains the action parameter values (create/list) but does not clarify label, limit, metadata, or idempotency_key. Schema coverage is 0%, so these parameters remain ambiguous despite self-explanatory titles.

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?

Clearly states the tool creates or lists project checkpoints, with specific action values. Differentiates from sibling tools by focusing on checkpoint capture/list rather than memory/commit/rollback operations.

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?

Explicitly advises using create before risky work, and notes list is free and returns newest first. Does not name alternative tools but provides context for when each action is appropriate.

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