A privacy-first, maintainer-ready bug report draft from local repository metadata.
reprokit turns scattered context around a failed build into two local files: a human-editable repro.md and machine-readable repro.json. It does not upload data, open GitHub issues, read .env values, include Git remotes, include diffs, or run your application commands.
The promise: make the first maintainer reply less likely to be “Can you share your environment, lockfile state, Git state, and reproduction steps?”—without sending source code or secrets anywhere.
ReproKit is an early beta. The preferred path after the first npm release is:
npx @aaserag/reprokit --output .reprokit --title "Build fails after dependency update"Until that release is visible on npm, use the source-install path below.
Issue templates help contributors structure a report, while environment-reporting tools focus on operating-system and runtime versions. ReproKit focuses on the missing handoff: a concise, privacy-reviewed snapshot of a specific repository plus clear placeholders for the human reproduction steps.
git clone https://github.com/aaserag1/reprokit.git
cd reprokit
npm ci
node bin/reprokit.mjs --output .reprokit-demo --title "Build fails after dependency update"To run the CLI against another project, use the local executable from that project directory:
node /path/to/reprokit/bin/reprokit.mjs --output .reprokit --title "Describe the failure briefly"This writes a report directory:
.reprokit/
├── repro.md # paste into a GitHub issue after review
└── repro.json # structured metadata for tooling
repro.md is a ready-to-edit GitHub issue draft. It contains clearly marked placeholders for the human parts of a useful report: what happened, the smallest reproduction, expected behavior, and actual behavior. repro.json carries the same safe metadata for tooling.
# Build fails after dependency update
## Steps to reproduce
<!-- Add the smallest sequence of commands or interactions that triggers the problem. -->
## Project snapshot
- Ecosystems: node
- Lockfiles:
- package-lock.json (sha256: ...)Before sharing either file, review it yourself. ReproKit reduces risk; it cannot know every private detail in your project.
| It does | It does not do |
|---|---|
| Detect ecosystem files, lockfile hashes, runtime versions and compact Git state | Read source-code content, manifest content, .env values, Git remotes, diffs or commit history |
Write repro.md and repro.json locally |
Upload a report, create an issue, contact an API or run project test/build scripts |
| Redact common token patterns before serializing output | Guarantee that a report contains no sensitive context; human review remains mandatory |
| Category | Included | Explicitly excluded |
|---|---|---|
| Project | Detected ecosystem, manifest names, lockfile SHA-256 hashes, package script names | Source-code content and manifest content |
| Runtime | Node, Python, Go and Rust version strings when available | Local binary paths |
| Git | Branch, short commit, changed-file count and untracked-file flag | Remote URL, diff, file names and commit history |
| Privacy | A summary of redaction categories | Environment variable values and .env values |
ReproKit is intentionally conservative. It only executes version checks and read-only Git metadata commands. Before writing output, it replaces common secret shapes such as GitHub tokens, AWS access keys, JWTs, URL credentials and token=value style assignments. This is a safety net, not a substitute for manually reviewing a report before sharing it.

npm run check
node bin/reprokit.mjs --output .reprokit-demoA ready-to-use GitHub Actions workflow lives at docs/github-actions-test.yml. Copy it to .github/workflows/test.yml after the repository token or account has permission to create workflow files. The workflow runs the unit tests and syntax checks on Node.js 18, 20 and 22.
New contributors are welcome, especially for ecosystem detectors, redaction rules, report wording, test fixtures, and accessibility/readability improvements in the generated Markdown. Start with the first-contribution guide, then read CONTRIBUTING.md and the security policy.
The first release targets Node, Python, Rust and Go repositories. Future versions may add opt-in issue-template mapping, custom safe collectors, and integrations with GitHub CLI. ReproKit will keep external uploads and automatic issue creation opt-in.
