Event output

Event output settings control the size of agent message and tool previews in runtime events.

Configure event output

Skiller uses the event output section from the agent profile first. Select the profile in the workflow YAML:

- agent: reviewer
  config:
    file: "~/.skiller/profiles/agent.reviewer.json"

If the profile has no such section, Skiller uses the settings in ~/.skiller/settings/agent.json, the global agent configuration. If neither defines it, Skiller uses the defaults below.

The profile replaces the entire section. Omitted fields use their defaults rather than inheriting individual global values.

Event output section shape

Both files use the same structure:

{
  "event_output": {
    "truncate": {
      "enabled": true,
      "max_text_chars": 600,
      "max_json_chars": 4000,
      "max_array_items": 20
    }
  }
}

Fields

Field	Description	Default
truncate.enabled	Enables truncation of event previews.	true
truncate.max_text_chars	Maximum text characters in a preview.	600
truncate.max_json_chars	Character limit used for JSON previews.	4000
truncate.max_array_items	Maximum array items retained in a preview.	20

What truncation affects

These limits shorten event previews, not the agent’s conversation context or the underlying step results. They are not a context-window or tool-result budget.

All three size limits must be positive integers. Set truncate.enabled to false to disable preview truncation; events may then contain much larger payloads.

Defaults

These values apply in memory when neither configuration defines the section; Skiller does not create a file with this JSON:

{
  "event_output": {
    "truncate": {
      "enabled": true,
      "max_text_chars": 600,
      "max_json_chars": 4000,
      "max_array_items": 20
    }
  }
}
