OpenAI summaries are optional and explicitly opt-in.\n\nStatus:early public beta, stable release`v0.2.0`\n\n. The project is intentionally small, dependency-free, auditable, and contributor-friendly. OSSBeacon also dogfoods the current`main`\n\nbranch on its own pull requests.\n\nMaintainers spend a surprising amount of time routing attention rather than writing code. OSSBeacon is designed as a transparent first-pass signal, not an autonomous gatekeeper.\n\n- 🟢\n**Free baseline:** no AI key required. - 🔍\n**Transparent:** risk factors are shown, not hidden behind a score. - 🤖\n**Optional AI:** use the OpenAI Responses API only when you request it. - 🔐\n**Privacy-conscious:** AI mode sends compact metadata, not arbitrary repository source files. - 🧩\n**Zero runtime dependencies:** Node.js 20+ is enough. - ⚙️\n**GitHub Action ready:** put the report in your workflow summary, optionally comment on PRs.\n\nThe lowest-risk first trial is read-only, AI-off, and pinned to the stable release. Copy [ examples/workflow.yml](/closedfiles23-web/ossbeacon/blob/main/examples/workflow.yml) into your repository as\n\n`.github/workflows/ossbeacon.yml`\n\n.That baseline uses `pull-requests: read`\n\n, does not require an OpenAI key, and writes the report to the GitHub Actions job summary. If the signal is useful, you can later enable a duplicate-free managed PR comment, tune repository-specific risk rules, or opt into AI.\n\nFor the complete progression, including fork safety and least-privilege permissions, see ** Adopting OSSBeacon**. After a real trial,\n\n**with useful signals, false positives, missing signals, or setup friction.**\n\n[share an adoption report](https://github.com/closedfiles23-web/ossbeacon/issues/new?template=adoption.yml)\n\n```\ngit clone https://github.com/closedfiles23-web/ossbeacon.git\ncd ossbeacon\nnpm test\nnode src/cli.mjs demo\n```\n\nAnalyze a public PR:\n\n```\nnode src/cli.mjs analyze-pr --repo owner/project --pr 123\n```\n\nFor private repositories or higher GitHub API limits:\n\n```\nexport GITHUB_TOKEN=\"...\"\nnode src/cli.mjs analyze-pr --repo owner/private-project --pr 123\n```\n\nEnable the optional AI maintainer summary:\n\n```\nexport OPENAI_API_KEY=\"...\"\nnode src/cli.mjs analyze-pr --repo owner/project --pr 123 --ai\n```\n\nThe OpenAI integration uses the Responses API. The default model can be changed through `OSSBEACON_MODEL`\n\nor `.ossbeacon.json`\n\n.\n\n```\nossbeacon analyze-pr --repo owner/project --pr 123\nossbeacon analyze-pr --repo owner/project --pr 123 --json\nossbeacon analyze-pr --repo owner/project --pr 123 --ai\n```\n\nThe report considers change size, number of files, sensitive paths, obvious test changes, and configurable thresholds.\n\n```\nossbeacon triage-issue --repo owner/project --issue 42\n```\n\nIt proposes a type, labels, priority, and evidence. The heuristic is deliberately conservative.\n\n```\nossbeacon release-notes --repo owner/project --from v1.0.0 --to v1.1.0\n```\n\nConventional Commit prefixes are grouped into features, fixes, docs, maintenance, and other changes.\n\nAdd `--json`\n\nto any maintainer command to emit the versioned OSSBeacon report contract rather than internal GitHub API payloads.\n\n```\nossbeacon analyze-pr --repo owner/project --pr 123 --json\nossbeacon triage-issue --repo owner/project --issue 42 --json\nossbeacon release-notes --repo owner/project --from v1.0.0 --to v1.1.0 --json\n```\n\nReports include `schemaVersion`\n\nand `reportType`\n\n. The v1 contract, compatibility policy, and privacy guarantees are documented in [docs/REPORT_SCHEMA.md](/closedfiles23-web/ossbeacon/blob/main/docs/REPORT_SCHEMA.md), with a formal JSON Schema at [schemas/report-v1.schema.json](/closedfiles23-web/ossbeacon/blob/main/schemas/report-v1.schema.json).\n\nExternal repositories should pin the stable release:\n\n```\nname: OSSBeacon\non:\n  pull_request:\n    types: [opened, synchronize, reopened, ready_for_review]\n\npermissions:\n  contents: read\n  pull-requests: read\n\njobs:\n  review-signal:\n    runs-on: ubuntu-latest\n    steps:\n      - uses: closedfiles23-web/ossbeacon@v0.2.0\n        with:\n          github-token: ${{ github.token }}\n          use-ai: 'false'\n          comment: 'false'\n```\n\nStable `v0.2.0`\n\nincludes duplicate-free managed PR comments. When `comment: 'true'`\n\nis enabled, OSSBeacon marks its own report and updates that marked comment on later runs instead of posting duplicates or editing unrelated human and bot comments.\n\nFor least privilege, use `pull-requests: read`\n\nwhen comments are disabled. Creating or updating an OSSBeacon PR comment requires `pull-requests: write`\n\n. `contents: read`\n\nis sufficient for the Action's repository access.\n\nTo enable AI, store an OpenAI API key as a repository secret and pass it to `openai-api-key`\n\n. Do not place API keys in workflow files.\n\nOSSBeacon analyzes its own pull requests through [ .github/workflows/ossbeacon.yml](/closedfiles23-web/ossbeacon/blob/main/.github/workflows/ossbeacon.yml). That workflow deliberately uses the trusted Action from\n\n`@main`\n\n, keeps AI disabled, and does not check out or execute pull-request code.For same-repository branches it can maintain one OSSBeacon PR comment. For forked pull requests it leaves commenting disabled and still provides the workflow summary. This lets the project exercise current behavior without making external contributors depend on privileged tokens.\n\nDownstream projects should continue to use the stable release tag rather than copying this development-only `@main`\n\nchoice.\n\nCopy `.ossbeacon.example.json`\n\nto `.ossbeacon.json`\n\nand adjust thresholds, sensitive path patterns, or GitHub retrieval limits.\n\n```\n{\n  \"github\": {\n    \"maxPrFiles\": 1000\n  },\n  \"risk\": {\n    \"highThreshold\": 70,\n    \"mediumThreshold\": 35,\n    \"largeChangeLines\": 600\n  }\n}\n```\n\n`github.maxPrFiles`\n\nis a safety cap. OSSBeacon paginates changed files up to that limit and clearly warns when a larger PR is intentionally truncated.\n\n**Assist, do not replace maintainers.** Scores never merge or reject code automatically.**Explain signals.** Every risk score comes with human-readable factors.**Minimal data.** AI mode gets compact PR or issue metadata rather than complete source files.**Safe defaults.** Commenting and AI are disabled by default.**Portable core.** No framework or runtime dependency beyond modern Node.js.\n\nSee [ROADMAP.md](/closedfiles23-web/ossbeacon/blob/main/ROADMAP.md).
