Capture System Snapshot

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed world, so safety is covered. The description adds the coverage list (CPU, RAM, Processes), but says nothing about cost, snapshot retention, freshness, or how the result is delivered beyond what the output schema will show.

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?

One crisp sentence leads with the verb and scope, and nothing is redundant. The appended CONCEPT taxonomy string adds no decision-relevant information and slightly dilutes the front-loaded clarity.

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?

With an output schema present, the description need not explain return values, and the zero-parameter signature keeps the call surface trivial. The only meaningful gap is the missing routing guidance against the many health/process siblings.

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 tool takes zero parameters, so the baseline is 4. There is no parameter surface the description needs to explain, and it does not confuse the reader with any.

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?

States a specific verb (takes a point-in-time snapshot) and resource (system state), and enumerates the captured dimensions (CPU, RAM, Processes), so the agent knows exactly what it produces. It does not distinguish itself from overlapping siblings such as health_check or get_process_details, which limits it to a 4.

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?

There is no statement of when to call this versus health_check, get_process_details, start_system_trace, or the sm_*_operations siblings, and no prerequisites or exclusions. The agent must infer usage entirely from the phrase 'point-in-time snapshot'.

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