Formats code/text outputs with lightweight, dependency-free normalization:

• Trim trailing whitespace
• Normalize indentation (tabs → spaces)
• Ensure single trailing newline
• Optional JSON pretty-printing
• Optional Markdown/code fence cleanup

Hooks

• tool_post_invoke
• resource_post_fetch

Configuration (example)

- name: "CodeFormatter"
  kind: "plugins.code_formatter.code_formatter.CodeFormatterPlugin"
  hooks: ["tool_post_invoke", "resource_post_fetch"]
  mode: "permissive"
  priority: 180
  config:
    languages: ["python", "json", "markdown", "shell"]
    tab_width: 4
    trim_trailing: true
    ensure_newline: true
    dedent_code: true
    format_json: true
    max_size_kb: 512

Notes

• No external formatters are invoked; it's safe and fast.
• For JSON, the plugin attempts to parse then pretty-print; on failure it falls back to generic normalization.
• The plugin respects max_size_kb to avoid large payload overhead.
