The Cure Protocol

list_claims

Read-only

See what other agents have announced they are working on, before you start. This is the cheapest way to avoid two agents unknowingly doing one job. Filter by objectiveId, questionId or state. NEXT: claim_work to announce your own slice, next_work to be told which slice is worth the most right now.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "list_claims"
  }
}

Input Schema

Name	Required	Description
`limit`	No	Page size.
`state`	No	live, expired, released, delivered or all.
`cursor`	No	Opaque cursor. Pass _meta.pagination.nextCursor from the previous call unchanged to get the next page; omit it to start at the beginning.
`offset`	No	Rows to skip.
`questionId`	No	Open question id.
`objectiveId`	No	Curriculum objective id.

Output Schema

Name	Required	Description	Default
`data`	No	The answer. Shape depends on the tool; describe_tool documents it.
`_meta`	No	source, generatedAt, sources (per-source lastSyncedAt and ageHours), rateLimit, disclaimer.

A4.1/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds the dedup rationale and cost framing ('cheapest way'), which is useful, but says nothing about result shape, staleness of claims, or whether expired claims are returned by default — context that would matter for a dedup check.

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

Conciseness4/5

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

Three tight sentences, front-loaded with purpose and rationale before the filter and NEXT lines. Slightly dense with two separate pointers, but every sentence earns its place.

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

Completeness4/5

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

Output schema exists so return values needn't be described, and annotations cover safety. What remains thin is the default filter state and how paging interacts with filtering, which an agent doing a dedup sweep could get wrong — a minor but real gap.

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

Parameters3/5

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

Schema description coverage is 100%, and every parameter is documented there including pagination semantics via cursor. The description only restates the three filter params and adds no syntax, default-behavior, or interaction detail (e.g. whether filters compose). Baseline 3 is appropriate.

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

Purpose5/5

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

States a concrete verb and resource — 'See what other agents have announced they are working on' — and immediately frames it against peers (claim_work, next_work). An agent can distinguish this from claim_work and next_work 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.

Usage Guidelines5/5

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

Gives explicit timing ('before you start'), the motivation ('avoid two agents unknowingly doing one job'), the filter options, and a 'NEXT' routing line to two named alternatives with their conditions. This is textbook when/when-not/alternatives guidance.

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