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

With no annotations provided, the description carries the full burden. It mentions the tool retrieves GPOs and their security relevance, but does not disclose behavioral traits such as rate limits, authentication needs, error handling, or response format. It adds some context about GPOs being key for identifying edges, but lacks operational details.

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 appropriately sized with three sentences: purpose, GPO explanation, and security context, followed by a structured Args section. It is front-loaded with key information, though the security sentence could be more integrated. Minimal waste, but slightly verbose in the explanation.

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 no annotations, no output schema, and 3 parameters with 0% schema coverage, the description is moderately complete. It covers purpose, parameters, and some security context, but lacks details on return values, error cases, or performance considerations. Adequate for basic use but with gaps for full operational understanding.

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 description coverage is 0%, so the description must compensate. It adds meaning by explaining 'domain_id' as 'The ID of the domain to query', 'limit' as 'Maximum number of GPOs to return (default: 100)', and 'skip' as 'Number of GPOs to skip for pagination (default: 0)'. This clarifies purpose and defaults beyond the bare schema, though it could provide more on parameter constraints or examples.

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 verb 'Retrieves' and resource 'Group Policy Objects (GPOs)' with specific context 'from a specific domain in the Bloodhound database.' It distinguishes from siblings by focusing on GPO retrieval rather than other entities like users, computers, or groups, and explicitly mentions GPOs are for policy settings in Active Directory.

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 for querying GPOs in a domain, particularly for security analysis ('abused for persistence and privilege escalation'), but does not explicitly state when to use this tool versus alternatives like 'get_gpo_info' or 'get_linked_gpos'. It provides context but lacks direct comparison or exclusion criteria.

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