Commit Miner
A Rust CLI that classifies Git commit diffs and messages with Jev into bug fixes, security fixes with CWEs, and change types, then writes HTML or CSV reports from saved scans.

About this project
Classify Git commit diffs and messages with Jev. Bug fixes, security fixes/CWEs, and change types. commit-miner scan --help lists all arguments. commit-miner categories lists classifications/CWEs. Filters preserve the full saved scan. Managed GitHub clones refresh automatically; local directories use their current HEAD. New scans show estimated Jev cost from reported token usage and known model pricing. Calculation details.

Highlights
- Scans the latest N commits, exactly one SHA or ref, or an inclusive UTC date range, against a local directory or a managed GitHub clone.
- Filters --only security,change_performance and --cwe 79,89 narrow the displayed classifications while the full saved scan is preserved.
- Reports estimate Jev cost from reported token usage and known model pricing; scans are saved under ~/.local/share/commit-miner with list, show, and export.
- Runs up to 8 workers by default and maximum, writes HTML or CSV, and Ctrl+C retains completed results.
- Ships an agent skill for codex, claude, or opencode via commit-miner install-skill.
Quickstart
bash
git clone https://github.com/devanshbatham/commit-miner.git
cd commit-miner
cargo install --path . --locked
export TYPESAFE_API_KEY="YOUR_API_KEY"
commit-miner scan . -n 500 -o report.htmlWatch out
No license file, so reuse terms are unclear. Needs Rust/Cargo, Git, and a TYPESAFE_API_KEY; managed GitHub clones refresh automatically while local directories use their current HEAD.
Questions about this entry
Short answers drawn from the linked project or page.
Both, and the diff is the point. It classifies commit diffs and messages into bug fixes, security fixes mapped to CWEs, and change types, so a message claiming a fix can be weighed against what actually changed. `commit-miner categories` prints the full classification and CWE vocabulary. What the README does not include is the exact question wording sent to Jev; docs/JEV_PROTOCOL.md is linked for the cost calculation.
Every new scan prints an estimated Jev cost computed from the token usage Jev reported plus known model pricing, so you see it at run time. The README documents no fixed price per commit and no hard spending cap flag, so if cost matters start with a narrow slice such as --commit or a --since/--until window instead of -n 500. Filters like --only security or --cwe 79,89 narrow only the display.
Both behaviours exist and which one you get depends on the target. A managed GitHub clone refreshes automatically, so scanning a repository URL picks up new commits, while a local directory is read at its current HEAD, which means uncommitted work is out of scope. Scans are saved under ~/.local/share/commit-miner on Linux, overridable with --data-dir, and Ctrl+C keeps whatever finished.
Rust and Git, and it installs from source rather than a registry package: clone, cargo install --path . --locked, then export TYPESAFE_API_KEY. There is no offline mode, so a key is required even for a single-commit probe such as scan . --commit SHA. An agent skill is bundled and installs for codex, claude, or opencode via commit-miner install-skill.
Yes. --commit SHA_OR_REF scans exactly one commit and cannot combine with count or dates, while --since and --until take inclusive UTC committer dates.
Yes. Scans are saved locally, listed with commit-miner list, inspected with show SCAN_ID, and exported with export SCAN_ID -o report.html; filters such as --only security narrow the display but preserve the full saved scan.
Run commit-miner install-skill all, or choose one with codex, claude, or opencode, then restart your harness; the bundled SKILL.md covers binary installation, arguments, and saved-result commands.
