OpenCodeCommit

AI commit messages via terminal AI agents. VSCodium / VS Code extension + standalone Rust / npm CLI.

Security scanning built in — diffs are scanned locally for secrets, source maps, and private keys before anything leaves your machine.

VSCodium Open VSX registry
VS Code Marketplace · npm · crates.io · GitHub

Install

Extension: Search "OpenCodeCommit" in VSCodium / VS Code, or ext install Nevaberry.opencodecommit

CLI: cargo install opencodecommit or npm i -g @nevaberry/opencodecommit (installs occ command)

Prerequisite: At least one CLI backend:

Backend	Install
Codex CLI	npm i -g @openai/codex
OpenCode	npm i -g opencode
Gemini CLI	npm i -g @google/gemini-cli
Claude Code	npm i -g @anthropic-ai/claude-code

VSCodium / VS Code Usage

1. Stage changes (or leave unstaged — auto-detected)
2. Click the sparkle button in Source Control
3. Commit message appears in the input box

Dropdown menu: mode-specific generation, refine, branch name generation, switch language, diagnose.

CLI Usage

occ commit                         # generate message + commit
occ commit --dry-run               # preview only, don't commit
occ commit --language Suomi        # generate in Finnish
occ branch                         # generate branch name + checkout
occ branch --mode adaptive         # match existing branch naming style
occ pr                             # generate PR title + body
occ changelog                      # generate changelog entry

# JSON output (default), or --text for human readable plain text
occ commit --text
occ commit --allow-sensitive       # skip secret scanning

occ is the short form. opencodecommit also works if occ clashes with something on your system.

Exit codes: 0 success, 1 no changes, 2 backend error, 3 config error, 5 sensitive content detected

Sensitive Content Detection

Diffs are scanned locally before being sent to any AI backend. The CLI blocks (exit 5) and the extension shows a warning dialog.

Flagged file names:

Category	Patterns
Environment / secrets	.env*, credentials.json, secret.*, secrets.*, .netrc, service-account*.json
Source maps	*.js.map, *.css.map, *.map — can expose full source code
Private keys / certs	*.pem, *.key, *.p12, *.pfx, *.keystore, *.jks
SSH keys	id_rsa, id_ed25519, id_ecdsa, id_dsa, .ssh/*
Auth files	.htpasswd

Category	Patterns
Generic secrets	API_KEY, SECRET_KEY, ACCESS_TOKEN, AUTH_TOKEN, PRIVATE_KEY, PASSWORD, DB_PASSWORD, DATABASE_URL, CLIENT_SECRET, CREDENTIALS
Service-specific	AWS_SECRET, GH_TOKEN, NPM_TOKEN, SLACK_TOKEN, STRIPE_SECRET, SENDGRID_KEY, TWILIO_AUTH
Token patterns	Bearer <20+ chars>, sk-<20+ chars>, ghp_<20+ chars>, AKIA<12+ chars>

Configuration

All VSCodium / VS Code settings are prefixed with opencodecommit.. Key settings:

Setting	Default	Description
backendOrder	["codex","opencode","claude","gemini"]	Backend fallback order
commitMode	adaptive	adaptive, adaptive-oneliner, conventional, conventional-oneliner
branchMode	conventional	conventional or adaptive (matches existing branch names)
diffSource	auto	auto, staged, or all
languages	English, Suomi	Array of language configs with custom prompt modules
commitTemplate	{{type}}: {{message}}	Supports {{type}}, {{emoji}}, {{message}}

CLI config: ~/.config/opencodecommit/config.toml (TOML with the same fields in kebab-case).

Languages

Built-in: English (default), Suomi (Finnish), Custom (example) (template for your own).

Each language defines full prompt modules (base, adaptive, conventional, length, sensitive note). Missing modules fall back to English. CLI: --language Suomi. Extension: dropdown menu or opencodecommit.activeLanguage setting.

Add custom languages in config — only label and instruction are required:

[[languages]]
label = "Deutsch"
instruction = "Schreibe die Commit-Nachricht auf Deutsch."
