host.tool_test

Dry-run a published tool by name: verdict (pass/will_fail/unverifiable), writes rolled back (dry_run); see host.quickstart.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "name": "<name>"
    },
    "name": "host.tool_test"
  }
}

Input Schema

NameRequiredDescriptionDefault
argsNoArguments to pass, same shape as a real call. Omit to run one example generated from the tool's args_schema; the response then carries example_args (what ran) and untyped (keys the schema gave no type for).
nameYesLocal name of the already-published tool to dry-run.
fixturesNoChain tools only: {"<step number or tool name>": <recorded result>}. A fixtured step executes nothing (no upstream call); later mappings resolve against it. host.runs.get(run_id, as_fixtures=true) exports a real run in this shape.
tenant_keyNoThe key `signup` returned. Optional on the connection that ran signup (or host.redeem): that connection is already bound to the tenant it created, so later calls on it need no tenant_key. On a connection with no Authorization: Bearer header and no prior signup, omitting it implicitly signs that connection up as a brand-new tenant and runs this call as it -- see host.whoami's source field. When both a header and this argument are present, the header wins.

TDQS

A3.8/5.0
Behavior4/5

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

With no annotations, the description carries the full burden, and it does disclose the key behavioral trait: writes are rolled back in dry_run. It also names the verdict states, which tells the agent what to inspect. It omits auth/tenant implications and what a failed verdict means in practice.

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?

A single dense sentence with the core action front-loaded and no filler; the verdict enumeration and rollback note are packed efficiently. The quickstart pointer is short and actionable.

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?

An output schema exists, so return values need not be explained, and the schema fully covers the four parameters including nested objects. The description covers the essential contract (dry-run, rollback, verdict); only the fixture/chaining story is left entirely to the schema.

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 baseline is 3; every parameter including args, fixtures and tenant_key is already documented in the schema. The description adds little beyond re-stating that the tool is selected 'by name'.

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 and resource ('Dry-run a published tool by name') plus the outcome vocabulary (pass/will_fail/unverifiable), which lets an agent distinguish it from the real-call sibling host.tool_call. It stops short of naming that sibling explicitly, so differentiation is implied rather than stated.

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 only implied by 'Dry-run' and the pointer 'see host.quickstart'. There is no explicit statement of when to prefer this over host.tool_call, nor any exclusion such as 'cannot dry-run unpublished tools'.

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