Get workflow run

get_workflow_run
Read-onlyIdempotent

Read a workflow run, its recorded steps, generations, and current checkpoint. A run whose score builds a film reports it as storyboard: its id, name, scene count and app_url — read the board itself with get_storyboard.

Tool call template

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

  2. First observed

TDQS

A3.9/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, closed-world and non-destructive, so the safety profile is covered. The description adds genuinely non-obvious behavior: storyboard-backed runs are returned in a summarized form (id, name, scene count, app_url) rather than in full. It doesn't mention how a run_id is obtained or anything about run state transitions, but the summarization disclosure is the important surprise and it is stated.

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?

Two sentences, both carrying content: the first defines the payload, the second defines the exception and the escape hatch. The second sentence's clause ordering ("A run whose score builds a film reports it as storyboard") is harder to parse than it needs to be, which costs a point, but nothing is padding.

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 shape needn't be spelled out, yet the description still usefully flags the storyboard-summarization deviation an agent would otherwise misread. The one real gap is the run_id provenance link to list_workflow_runs, which is the missing piece for a first-time caller.

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 0%, so the description carries the burden for run_id and says nothing about it — not where to obtain it, nor that it must be a UUID identifying a specific run. The parameter name is largely self-describing and the input schema does supply format=uuid and required, which keeps this from being a 2.

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 opens with a specific verb+resource ("Read a workflow run") and enumerates what the read includes: recorded steps, generations, and current checkpoint. It also explicitly separates itself from get_storyboard. It loses a point because the phrase "a run whose score builds a film" is opaque jargon that an agent may not parse, and it doesn't distinguish itself from list_workflow_runs or get_generation.

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

Usage Guidelines4/5

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

It gives one piece of explicit routing guidance: when the run is a storyboard, read the board itself with get_storyboard rather than expecting full board data here. That is a concrete when-to-use-this-vs-alternative instruction. It stops short of stating the inverse condition (use list_workflow_runs to find a run_id) or any exclusions beyond storyboard content.

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