PacketFabric

pf_search_endpoints

Read-only

Search all PacketFabric API endpoints by keyword. Returns operation_ids to pass to pf_describe_endpoint / pf_call_endpoint.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

A4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds useful workflow context that results are operation_ids for describe/call, but it does not discuss pagination, limits, auth, or result behavior; with annotations carrying safety, this is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with purpose and followed by the return/handoff workflow. No wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given annotations, 75% parameter coverage, and an output schema, the description provides enough to understand the tool's role in endpoint discovery. It omits pagination/limit details, but those are either covered elsewhere or less critical.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 75% and already describes tag, query, and read_only; the description only restates keyword search. It adds no filter semantics beyond the schema, and limit remains undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: search all PacketFabric API endpoints by keyword. It also names the return artifact (operation_ids) and downstream tools, clearly distinguishing it from pf_call_endpoint and pf_describe_endpoint.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explains the discovery workflow: search by keyword, then pass returned operation_ids to pf_describe_endpoint or pf_call_endpoint. It does not explicitly say when to prefer pf_list_api_areas or when not to search, so it falls short of a full 5.

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