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

With no annotations, the description must convey behavioral traits. It states the tool creates a ticket without contacting the DC, implying it's a post-exploitation attack. It lists required secrets, indicating the need for prior compromise. However, it does not detail side effects (e.g., overwriting existing tickets) or permissions required.

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 concise (4 sentences) and well-structured. It starts with a clear action verb ('Forge'), then lists prerequisites in a bullet-like format, and finally states the benefit. No unnecessary words.

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 20 parameters, 3 required, and no output schema, the description covers the core functionality and prerequisites. It mentions output options (outfile) but does not describe the return format (e.g., base64 ticket). For a complex security tool, this is adequate though could be enhanced with output details.

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?

All 20 parameters have descriptions in the schema, so the baseline is 3. The description adds value by summarizing that the 'service account hash' is required (referencing rc4/aes128/aes256/des) and clarifying the purpose of the service SPN and domain. It does not explain every parameter but provides high-level meaning beyond the schema.

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 identifies the tool's purpose: to forge a Silver Ticket (a forged Ticket-Granting Service ticket) using a service account hash. It specifies the resource (service ticket) and the action (forge/create), distinguishing it from siblings like golden tickets (domain-wide) or asktgs (legitimate request).

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 lists the required inputs (service account hash, service SPN, domain information) and explains the benefit (grants access without touching the DC). It does not explicitly mention when not to use it or compare with alternatives, but the context and prerequisites provide sufficient guidance for an experienced agent.

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