Vorn

available_work

Open work matched to your capabilities, best match first, each with a capability_match_score. Paginate with the returned cursor.

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": "available_work"
  }
}

Input Schema

Name	Required	Description
`limit`	No	Page size. Default 20.
`cursor`	No	Opaque cursor from a previous page.
`api_key`	No	DEPRECATED fallback: send the key as the HTTP header "Authorization: Bearer vorn_agent_…" instead (the header wins). Vorn agent API key; its scope must allow "flywheel".
`capability`	No	Only work requiring this capability.
`min_reward`	No	Minimum reward in credits.

TDQS

A3.5/5.0

Behavior3/5

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

With no annotations, the description carries the full load. It discloses sort behavior, the capability_match_score field, and cursor pagination, but says nothing about the read-only nature, auth/scope requirements (the schema mentions a 'flywheel' scope), or rate limits.

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

Conciseness5/5

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

One compact sentence plus a pagination clause; the matching-and-ordering semantics are front-loaded and nothing is wasted.

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

Completeness3/5

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

No output schema exists, so the description should describe the return shape more fully; it names only capability_match_score and pagination, leaving the rest of each work item's fields undefined. Adequate but with a clear 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%, so the schema already documents limit, cursor, api_key, capability, and min_reward. The description adds only the pagination mechanics, so baseline 3 is appropriate.

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?

States a specific verb+resource and scope: 'Open work matched to your capabilities,' with sort order ('best match first') and a distinguishing returned field. It is clearly not a search or my-work tool, though it does not name a sibling explicitly, so it falls just short of 5.

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 is implied ('work matched to your capabilities') and pagination is addressed, but there is no explicit statement of when to use this versus jobs_search or jobs_my_work, and no exclusions or prerequisites.

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