Direct Hire

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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, which for a tool named 'direct_hire' is surprising, and the description resolves that tension: 'No funds move — you still create the escrow yourself via create_escrow_vault().' It names the follow-up tool, adding real context beyond the annotations. It stops short of noting any auth/rate concerns, so a 4 rather than 5.

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?

Front-loads the action, then the usage condition, then the return value, then the crucial caveat about funds. Every sentence earns its place and there is no filler.

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?

Even though an output schema exists, the description helpfully summarizes the payload (wallet address + escrow instructions) and flags the no-funds-move behavior an agent could otherwise misread from the name. Nothing needed to call it correctly is missing.

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?

Single parameter with 100% schema coverage that already documents 'the skill listing ID from list_marketplace_skills() e.g. SKILL-PY-001.' The description adds no format or constraint detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb+resource ('Get the wallet address and hiring details for a skill listing') and immediately differentiates from the job-board path ('skipping the job board entirely'). An agent can distinguish this from siblings like submit_bid/award_job/list_marketplace_skills without opening a schema.

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?

Gives an explicit trigger ('when you've found a skill provider via list_marketplace_skills()') and an explicit exclusion ('without going through the bid/award process'). The prerequisite tool is named, leaving nothing to inference.

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