FairScale Trust Gate

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

Annotations already provide readOnlyHint=false, openWorldHint=true, etc. The description adds context about reputation/trust flow and metadata stability, but does not fully disclose behavioral traits (e.g., side effects, state changes) beyond what annotations indicate. It adds some value but not comprehensive.

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 three sentences, front-loaded with the core action, and contains no fluff. Every sentence adds necessary context, making it highly concise and well-structured.

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's complexity, the description covers purpose and usage context well. With an output schema available, it does not need to detail return values. However, it could mention the outcome of 'passing the gate' and how it fits into the broader SAP workflow.

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 100%, so parameters are well-documented. The description does not add significant extra meaning beyond the schema, such as clarifying expected formats or valid ranges. Baseline 3 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 clearly states the verb 'Evaluate' and the resource 'agent with SDK FairScaleRegistry.trustGate,' and provides context about reputation and trust flow. It is specific but does not explicitly distinguish from the sibling tool 'sap_fairscale_score,' which likely has a similar focus.

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 gives a precondition ('after verifying the target agent PDA or wallet') and a caution ('keep hashes/attestation metadata stable and auditable'), implying when to use. However, it does not mention alternatives or when not to use, such as compared to 'sap_fairscale_score.'

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