Snapshot OpenWrt network state

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

The description adds useful behavioral context beyond the annotations: it reveals that the snapshot is 'bounded' (resource-limited) and that it is 'retained in memory' (a stateful side effect), which the read-only and non-destructive annotations do not convey. It does not contradict the 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?

The description is a single, well-structured sentence that front-loads the core action and purpose, with no unnecessary words or repetition of annotations.

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 adequately covers the tool's purpose and memory retention behavior, but it omits parameter semantics and does not explain how the retained snapshot is retrieved or used by sibling tools like compare_snapshots. Given the simplicity of the tool and the presence of annotations, the description is minimally viable but has clear gaps.

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 only parameter, 'detail', is documented in the schema with an enum (summary/full) and a default, but the description does not explain what the difference between these values is or how they affect the snapshot. With schema coverage at 0%, the description's silence on the parameter leaves its meaning ambiguous.

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 tool's function with a specific verb ('Collect') and resource ('bounded router-side network snapshot'), and explicitly mentions its purpose ('retain it in memory for later comparison'), distinguishing it from siblings like compare_snapshots (which performs the comparison) and capture_flow (which captures traffic).

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?

The description implies usage before comparison by stating 'retain it in memory for later comparison', but it does not explicitly state when to use this tool versus alternatives such as capture_flow or inspect_config_state, nor does it provide exclusion criteria or prerequisites.

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