AI-powered scoped git commits as a GitHub CLI extension, driven by the OpenCode CLI. Scopes map Conventional Commit scope names to path prefixes. They are generated from the repository file tree, stored in a local DuckDB database, and auto-regenerate whenever .gitignore changes. Changed files are grouped by scope and committed one scope at a time with generated type(scope): message subjects.

Install

gh extension install prdlk/gh-commit

Requirements

uv — Python package runner (handles dependencies automatically)
OpenCode — non-interactive AI runner (opencode run)
OpenCode Go access for the default model — opencode auth login (choose OpenCode Go) or set OPENCODE_API_KEY

By default, gh-commit uses opencode-go/gpt-5.6-luna: the fastest model in OpenCode Go's largest context tier (1.05M tokens). Override it with GH_COMMIT_OPENCODE_MODEL (any provider/model from opencode models).

Prompts run through a private opencode run --standalone server with an inline read-only gh-commit agent: every tool except read, glob, and grep is denied, so the model never modifies the working tree.

Usage

cd your-repo
gh commit init   # generate scopes for this repo
gh commit        # commit changes grouped by scope

Commands

Command	Behavior
`gh commit`	Full scoped-commit flow: group changed files by scope, generate a message per group, confirm, commit, offer to push
`gh commit init`	Generate scopes from the file tree via OpenCode; migrates legacy configs; confirms overwrite
`gh commit refresh`	Show current scopes, regenerate with existing scopes as context, confirm apply
`gh commit sync`	Create/update GitHub labels from scopes (color = first 6 hex chars of MD5 of the scope name)
`gh commit list`	Table of configured repositories: name, path, scope count
`gh commit remove`	Delete the current repo from the database after confirmation
`gh commit db-path`	Print the database file path
`gh commit version`	Print `gh-commit <version>`
`gh commit help`	Help, including the DB path and environment variable docs

Flags: --auto (skip confirmations), --push (auto-push).

Environment

Variable	Description
`GH_COMMIT_AUTO=1`	Skip all confirmation prompts
`GH_COMMIT_PUSH=1`	Auto-push after commits
`GH_COMMIT_NO_AUTO_REFRESH=1`	Don't auto-regenerate scopes when `.gitignore` changes
`GH_COMMIT_OPENCODE_CMD`	Override the OpenCode command (default `opencode`)
`GH_COMMIT_OPENCODE_MODEL`	Override the model (default `opencode-go/gpt-5.6-luna`)
`GH_COMMIT_OPENCODE_TIMEOUT`	Per-prompt timeout in seconds (default `120`)
`GH_COMMIT_DEBUG=1`	Show scope-response parse diagnostics

Storage

Scopes live in ${XDG_DATA_HOME:-~/.local/share}/gh-commit/gh-commit.db (DuckDB). Legacy .github/Repo.toml and .github/scopes.json files are migrated automatically on first run (the source file is archived as *.migrated.<timestamp>).

Manual acceptance

mkdir /tmp/accept && cd /tmp/accept && git init
mkdir -p src docs
echo 'package app' > src/app.go
echo '# Docs' > docs/README.md
gh commit init          # scopes generated and saved
echo '// change' >> src/app.go
echo 'More docs' >> docs/README.md
gh commit               # one commit per scope
git log --format='%s'   # verify type(scope): message subjects

Development

The extension is a bash launcher (gh-commit) that runs smartcommit.py with uv run --script; uv resolves the inline dependencies (duckdb, rich, questionary) automatically.

python -m py_compile smartcommit.py   # syntax check
bash -n gh-commit                     # launcher check
./gh-commit version                   # smoke test
