# Code Formatter Plugin
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)
```yaml
- 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.
