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

Annotations establish mutation-without-destruction (readOnlyHint=false, destructiveHint=false), and the description adds real behavioral context beyond them: it auto-negotiates, auto-quotes, auto-creates milestones/scope, and mock-funds escrow on testnet. It stops short of stating auth requirements or failure/rollback behavior.

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?

Three dense sentences with no filler: purpose first, then side effects, then outputs, then the testnet caveat. Slightly overloaded but every clause carries information.

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?

For a multi-step orchestration tool with no output schema, the description compensates by enumerating return values (jobId, scopeId, escrowId, quote, contract terms). The nested 'parameters' object remains vague, but overall an agent has enough to invoke it correctly.

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 five parameters are already documented in the schema. The description's only added parameter meaning is that testnet escrow is mock-funded, which loosely maps to the paymentMethod enum; 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?

The description names a specific composite verb-set ('fast-track paid job') and enumerates exactly what the single call accomplishes: negotiation, quote, escrow with milestones, and execution scope. It is clearly distinguishable from the step-by-step siblings (pcc_publish_request, fund_escrow, pcc_create_scope), though it never names one explicitly.

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?

'Fast-track' and 'one call from DHT discovery to funded escrow' imply the when: use this instead of chaining the individual escrow/scope/quote tools. However no explicit when-not, no prerequisites, and no named alternative are given, so usage is only implied.

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