roll_snapshot_timestamp

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

No annotations are provided, so the description bears full responsibility. It discloses the basic effect (timestamp change) and the default/UTC interpretation, but does not mention side effects, prerequisites, permissions, reversibility, or any impact on dependent objects.

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 very concise: a one-line summary followed by bullet-point parameter explanations. It is front-loaded with the core purpose and contains no unnecessary words.

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 parameter count (4) and absence of annotations, the description covers basic functionality and parameter details. An output schema exists (context signal), so return values are documented elsewhere. However, behavioral gaps (side effects, prerequisites) make it only minimally complete.

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 0%, so the description adds meaning for all 4 parameters: workspace, warehouse, snapshot_name, and new_dt (optional, defaults, UTC interpretation). It sufficiently explains their roles beyond the schema 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?

The description clearly states the action ('roll a snapshot's timestamp forward or reset to current') and the resource (snapshot's timestamp). It effectively distinguishes from sibling tools like create_snapshot or delete_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?

No guidance on when to use this tool versus alternatives (e.g., creating a new snapshot or deleting). Context signals show many snapshot-related siblings but the description offers no exclusions or usage scenarios.

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