get_recent_flow_activity

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behavioral traits: the tool provides a snapshot with specific time constraints (last 10-20 minutes), result limits (up to 50 flows), and intended use case (immediate analysis). It doesn't mention error conditions, authentication requirements, or rate limits, but provides substantial operational context beyond basic functionality.

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 efficiently structured with zero wasted sentences. It front-loads the core functionality, immediately provides critical constraints, then delivers clear usage guidelines with specific examples. Every sentence adds essential information about the tool's purpose, limitations, and appropriate use cases.

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 tool has no parameters, no annotations, and no output schema, the description provides excellent contextual completeness for a read-only query tool. It explains what the tool returns (recent flow activity snapshot), temporal scope, result limits, and when to use it versus alternatives. The main gap is lack of information about return format or error conditions, but for a zero-parameter tool with clear sibling differentiation, this is quite 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?

The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters since none exist, and instead focuses on the tool's operational characteristics and usage guidelines.

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 specific action ('Get recent network flow activity snapshot') and resource ('network flow activity'), with precise temporal scope ('last 10-20 minutes') and result limit ('up to 50 most recent flows'). It explicitly distinguishes this tool from its sibling 'search_flows' by emphasizing it's for immediate analysis only, not historical data.

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 provides explicit guidance on when to use this tool ('what's happening right now?', current security threats, immediate network issues) and when not to use it (historical analysis, getting more than 50 flows, daily/weekly patterns). It names the alternative tool ('search_flows') and specifies when to prefer it ('For comprehensive analysis, always prefer search_flows').

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