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

No annotations are provided, so the description carries the full burden. It mentions 'verified, tracked' and 'attribution' but does not disclose permissions required, side effects (e.g., whether a record is created), error handling for invalid option_id, or rate limits. The behavioral profile is substantially incomplete for a tool with no annotation coverage.

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 a single, front-loaded sentence with dense but useful context. 'PHASE 2 HANDOFF' is compact and informative, though the trailing parameter list is slightly crowded, keeping it from a perfect score.

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?

With no annotations and no output schema, the description should carry more behavioral and return-value context. It adequately identifies the tool's purpose and inputs but leaves gaps about what the generated link looks like, whether it expires, and what happens on failure.

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 the baseline is 3. The description reiterates sub_id, agent_ref, locale, and currency but adds no meaning beyond what the schema already documents with examples and detailed descriptions.

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 states a specific verb ('Generates') and resource ('verified, tracked affiliate deep link') with clear scope ('for any option_id returned by GEO360 search tools'). It distinguishes this handoff tool from search and booking siblings by tying its input to search outputs.

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 'PHASE 2 HANDOFF' framing and mention of 'option_id returned by GEO360 search tools' implies this tool should be used after a search, but it does not explicitly state when not to use it or name alternative tools like book_offer or hold_offer. Usage is inferable but not spelled out.

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