list_versions

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

No annotations provided; description lists return values (version number, timestamp, tag) but does not disclose side effects or read-only nature. For a read-only list operation, this is acceptable but incomplete without annotations.

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: one for purpose, one for return format. No wasted words, front-loaded with action.

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 description covers purpose and return format adequately for a simple parameter-less tool. Could mention if version list is sorted or filtered, but not critical. Missing reference to time-travel concept, but sufficient.

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?

No parameters exist; schema coverage is 100% (trivially). With 0 parameters, baseline is 4, and description adds no extra param info (unnecessary).

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 'List' and resource 'versions of the chunks table for time-travel'. It distinguishes from sibling tools like checkout_version and restore_version which involve actions on versions.

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 on when to use this tool vs alternatives (e.g., checkout_version, restore_version). The phrase 'for time-travel' hints at context but does not explicitly state when-not or provide comparisons.

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