Direct Hire

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

Even though the annotations already indicate readOnlyHint, idempotentHint, and non-destructive behavior, the description adds important context by explicitly stating 'No funds move — you still create the escrow yourself via create_escrow_vault().' This prevents a serious misunderstanding about whether direct_hire actually transfers money or creates an escrow.

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 well-structured with a clear opening statement, explicit usage conditions, a numbered typical flow, and a concise return list. Every sentence contributes useful information, and the most important fact — no funds move — is prominently stated.

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 single parameter, existing output schema, and the annotations, the description is complete. It explains what the tool returns, how it fits into the larger hiring workflow, and what side effects it does not have. An agent has enough context to call it correctly and interpret the result.

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?

The schema description for skill_id is already complete (100% coverage) with an example format, so the description does not need to add much. It mentions skill_id in the flow and example call, but does not add new parameter-level meaning beyond what the schema already provides. 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 a specific action and resource: getting the wallet address and hiring details for a skill listing. It explicitly distinguishes itself from the job board flow and names the related sibling tools, so an agent can immediately understand what direct_hire does and how it differs.

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 explicitly says when to use this tool: after finding a provider via list_marketplace_skills() and when wanting to hire without the bid/award process. It also provides a typical three-step flow with create_escrow_vault(), which is strong practical guidance beyond just a vague 'use this for direct hiring.'

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