take_snapshot

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

No annotations are provided, so the description carries full burden. It states the tool saves a snapshot but does not disclose behavioral details like persistence, overwrite behavior, or side effects on the capture buffer. Adequate but incomplete.

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 concise, well-structured with a bullet-like workflow, and every sentence adds value. No redundant or filler content.

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 low complexity (single string parameter, no output schema), the description covers the core usage and purpose. However, it omits details like return value or behavior on duplicate names, which would be helpful but not critical.

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?

With 0% schema description coverage, the description must compensate. It adds 'name: Snapshot label,' which is a slight improvement over the schema's 'Name' but lacks constraints like uniqueness or length limits. Baseline 3 is appropriate.

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 explicitly states 'Save the current capture buffer as a named snapshot' with a specific verb and resource, and the step-by-step before/after workflow clearly distinguishes it from siblings like compare_snapshots and capture.

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?

Provides a concrete usage workflow with steps and an example (idle, throttle_pressed), making it clear when to use this tool. Lacks explicit when-not-to-use or alternatives, but the context of sibling tools compensates.

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