Agent SLA Rail

wever_agent-sla-rail

Destructive

Paid URL: 0.10 USDC per call on Base; 10 signed-wallet free calls shared over rolling 30 days. Read the backend 402 body for x402 terms. Record wallet-scoped SLA terms and evaluate deadlines against retained completed-work or callback observations. Operating boundary: Wallet-declared terms and evaluation at call time. No counterparty consent, background scheduling, retry execution, contractual enforcement or compensation is implied. POST /api/agent-sla-rail. Existing product credentials, signed mandates, and single-use action grants remain required where applicable. This adapter grants no authority and never supplies server credentials. Wallet-authenticated bounded operations service with durable records. See /api/operations-contract for exact schemas, verified scope and unavailable capabilities.

B3.2/5.0

Behavior4/5

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

Annotations already declare destructive=true, idempotent=false, openWorld=true, but the description adds material context they do not carry: the exact price (0.10 USDC per call on Base), the rolling-30-day free-call allowance shared across signed wallets, the no-authority/no-credential stance, and that records are durable. This is genuinely additive. It stops short of explaining what gets mutated per mode or what the retry_limit actually triggers, keeping it out of 5 territory.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and front-loads the pricing/402 mechanics before the actual purpose, which is arguably the wrong lead for an agent deciding whether to call it. Several sentences are boilerplate ('See /api/operations-contract,' 'This adapter grants no authority'), and none of the freed space is used to explain the modes.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 10 parameters, a three-way oneOf discriminator, no output schema, and annotations that only give coarse hints, the description does not explain which mode to select, what each mode returns, or how expected_work binds to the free-call/payment allowance. The heavy lifting is delegated to an external /api/operations-contract document the agent may not be able to read.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 10 parameters, so the description carries the full burden and largely fails: mode, idempotency_key, sla_id, callback_probe_id, expected_work kinds, usage enum, retry_limit, and deadline_at are never explained. Only loose echoes appear ('wallet-scoped SLA terms,' 'deadlines,' 'callback observations'), which do not tell the agent how to populate a three-variant oneOf.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a concrete dual purpose: 'Record wallet-scoped SLA terms and evaluate deadlines against retained completed-work or callback observations,' which is a specific verb+resource and separates it from siblings like escrow-lite or invoice-rail. It does not, however, surface the three operating modes (record/evaluate/retrieve) that the schema actually exposes, so the agent must open the schema to learn the tool does more than one thing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is implied (post to /api/agent-sla-rail, read the 402 body for x402 terms, credentials required where applicable) but there is no explicit when-to-use vs when-not-to-use guidance and no sibling alternative is named. The 'Operating boundary' paragraph usefully excludes non-goals (no enforcement, scheduling, or consent), which is stronger than nothing, but it is about scope rather than invocation choice.

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