Threat Hunting Bundle (Purple)

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

Adds significant value beyond annotations by detailing the bundled content (threat detail, IOCs, detection queries, etc.) and performance benefit. No contradiction with 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?

Extremely concise: two short sentences with no wasted words. Front-loaded with 'FLAGSHIP PURPLE TOOL' to immediately grab attention.

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?

Despite no output schema, the description enumerates what is included, making the tool's functionality clear. Combined with good annotations and simple parameters, it is 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?

Schema coverage is 100% and description does not add extra meaning beyond the schema's description of threat_id. Baseline score 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 uses specific verbs ('get') and resource ('threat hunting bundle') and clearly distinguishes from siblings like get_threat and get_threat_bundle by highlighting its comprehensive nature and Purple tier requirement.

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?

States when to use: 'Saves 5-7 MCP round-trips' and tier requirement. Does not explicitly mention alternatives like get_threat_bundle for non-Purple users, but context is clear.

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