Fields

provider: Provider

model: String

ollama_host: String

api_key: Option<String>

max_diff_lines: usize

max_file_lines: usize

max_context_chars: usize

Maximum context characters for LLM prompt (~4 chars per token) Default 24000 is safe for 8K context models

timeout_secs: u64

Request timeout in seconds (default 300)

temperature: f32

LLM temperature (0.0-2.0, default 0.3)

num_predict: u32

Maximum tokens to generate (default 256)

think: bool

Enable thinking/reasoning for Ollama models that support it (default: false) When enabled, thinking tokens are separated from the response. Requires higher num_predict (8192+) to accommodate thinking tokens.

openai_base_url: Option<String>

Base URL for OpenAI-compatible APIs (default: https://api.openai.com/v1)

anthropic_base_url: Option<String>

Base URL for Anthropic API (default: https://api.anthropic.com/v1)

rename_threshold: u8

Rename detection similarity threshold (0-100, default 70) Set to 0 to disable rename detection.

custom_secret_patterns: Vec<String>

Additional custom secret patterns (regex strings)

disabled_secret_patterns: Vec<String>

Built-in secret pattern names to disable

locale: Option<String>

Language for commit message generation (ISO 639-1 code, e.g., “de”, “ja”, “fr”) When set, the LLM is instructed to write in this language. Type/scope remain in English per Conventional Commits spec.

learn_from_history: bool

Enable experimental commit history style learning (default: false) Analyzes recent commits to learn scope naming, type patterns, and subject phrasing conventions for the repository.

history_sample_size: usize

Number of recent commits to sample for style learning (default: 50)

exclude_patterns: Vec<String>

Glob patterns for files to exclude from analysis and diff context Excluded files are listed in output but not sent to the LLM.

system_prompt_path: Option<PathBuf>

Path to custom system prompt file (overrides built-in SYSTEM_PROMPT)

template_path: Option<PathBuf>

Path to custom user prompt template file

format: CommitFormat

Commit message format options
