# overlane observe compare

{/* Generated by apps/docs/scripts/generate.mjs (CLI pages from the command registry in packages/cli). Do not edit; run `pnpm --filter @overlane/docs gen`. */}

For one task given to more than one agent, shows each agent's runs, cost, tokens, time and review outcome, and names the cheapest, the fastest and the lowest-cost agent whose work was approved.

## Usage

```sh
overlane observe compare --task TASK
```

## Flags

| Flag | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `--task` | string | yes |  | The task ID |

## Examples

```sh
overlane observe compare --task task-77
overlane observe compare --task task-77 --json
```

## Behavior

- Effect: `read` (changes nothing).
- Needs credentials: yes. Uses the network: yes.
- Supports `--dry-run`: no. Accepts `--force`: no.
- Machine-readable description: `overlane schema observe compare`.

## Result

With `--json` (the default when stdout is not a terminal) the command prints this JSON Schema's shape on stdout.
