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

Goes well beyond the annotations (which only say non-readonly, non-idempotent, non-destructive). It discloses timing of the held-payout release, that the returned status remains 'delivered' until settlement, the 7-day auto-release fallback with dispute exception, the 'tab' funding path that moves status to 'released' immediately, and the override semantics after a failed check.

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-loaded with the core action, and each subsequent sentence earns its place by covering a distinct case (settlement timing, auto-release default, tab funding, acceptance block, override). It is dense—nested parentheticals strain readability—but not padded.

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?

Covers the mutation's consequences, its timing behavior, alternate automatic paths, edge-case funding modes, and what the status looks like until completion—ample for a one-parameter mutation with no output schema. An agent can call this knowing exactly what it sets in motion.

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 coverage is 100% and the single parameter already documents 'UUID of the delivered quote thread to accept.' The description's reference to a 'delivered quote' reinforces the required state but adds little beyond what the schema and format pattern already supply.

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 and resource: 'Explicitly accept the deliverable on a delivered quote.' The 'delivered quote' qualifier implicitly distinguishes it from services_accept_quote and services_submit_deliverable, but no sibling is named, so an agent must infer the boundary rather than read it.

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 concrete conditions: use it after a fail/error verdict or while a check is pending (an override), and notes that without it funds auto-release after 7 days unless a dispute is filed. It also warns that on an acceptance-block quote a passing check has usually already paid out, which is a soft 'may be redundant' signal rather than an explicit exclusion.

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