<div align="center"> # GitContribute Contribution research for agents: check repository guidance, related work, code context, and validation before writing a patch. [](https://github.com/morluto/gitcontribute/actions/workflows/ci.yml) [](https://www.npmjs.com/package/gitcontribute) [](https://go.dev/) [](LICENSE) [](#platform-support) [Quick start](#quick-start) · [Workflow](#contribution-workflow) · [CLI](#cli) · [MCP](#mcp) · [Safety](#side-effect-boundaries) · [Documentation](#documentation)  </div> `gitcontribute` is available as a CLI, terminal UI, and MCP server for coding agents. GitHub can show you open issues. It cannot tell you whether an issue is still relevant, already being implemented, appropriate for an outside contributor, or supported by enough evidence to work on safely. GitContribute collects repository guidance, related issues and pull requests, code context, accepted contribution patterns, and validation results in a local SQLite corpus. Results identify missing or stale coverage. ```text find work -> understand it -> check competing work -> prove the change -> prepare the handoff ``` > [!IMPORTANT] > GitContribute never writes to GitHub. It prepares local research and drafts > for you to review. ## Quick start Run the guided setup with Node.js 18 or newer: ```sh npx --yes gitcontribute@latest setup ``` Choose **MCP** to use GitContribute from a supported coding agent, **CLI** for the terminal and TUI, or **Both**. The wizard shows every planned change before applying it. Adding a repository during setup does not contact GitHub or start a sync. After setup, start with a repository or an exact issue: | Task | Coding agent | CLI | | --- | --- | --- | | Find candidates | `Find contribution candidates in owner/repo. Rank them by contribution fit, evidence, scope, and coordination risk.` | `gitcontribute archive sync owner/repo`<br>`gitcontribute radar owner/repo --limit 10` | | Research an issue | `Investigate owner/repo#42. Check guidance, discussion, code, prior fixes, competing work, and missing evidence.` | `gitcontribute archive sync owner/repo --numbers 42`<br>`gitcontribute research brief issue:owner/repo#42` | Results include source references, coverage gaps, and suggested next steps. <details> <summary><strong>Other installation options</strong></summary> Install a persistent command: ```sh npm install --global gitcontribute@latest gitcontribute setup ``` Pin GitContribute to a project: ```sh npm install --save-dev gitcontribute npm exec -- gitcontribute setup --mode mcp --codex --token-source none --yes ``` Build from source with Go 1.26 or newer: ```sh go install github.com/morluto/gitcontribute/cmd/gitcontribute@latest ``` Native npm binaries are included for macOS ARM64/x64, Linux ARM64/x64, and Windows x64. You also need `git`. The `gh` CLI is optional and can provide authentication through `gh auth token`. </details> ## Contribution workflow ### 1. Find a candidate Search a repository or rank its open issues by available evidence, scope, risks, blockers, and signs that maintainer coordination is needed. ```text Find contribution candidates in golang/go. Exclude issues with active implementation work and explain why each remaining candidate is worth investigating. ``` The ranking only covers stored observations. Results report incomplete coverage. ### 2. Research an issue Build a research brief from the issue, repository guidance, discussion, linked work, indexed code, and historical contributions. Extracted maintainer text and checkboxes are not presented as complete acceptance criteria. ```text Investigate issue owner/repo#42. Summarize the confirmed problem, likely scope, relevant code, maintainer guidance, and open questions. ``` ### 3. Check related work Look for duplicate reports, linked pull requests, closing relationships, and semantically overlapping work before investing in an implementation. ```text Check whether owner/repo#42 has duplicate reports or competing implementation work. Tell me what you checked and identify any missing coverage. ``` Incomplete coverage is reported instead of being treated as proof that no competing work exists. In the MCP workflow, follow the returned typed recovery action, poll the durable job, and reread the affected exact thread or repository before drawing that conclusion. ### 4. Validate a change Record a reproduction, test, benchmark, or other validation and compare the unmodified baseline with a candidate. Validation commands run only after explicit approval. ```text Validate my candidate change against the baseline. Run the approved checks, record both results, and explain whether the evidence supports the change. ``` Stored runs include the command, outcome, timing, and available process metrics. ### 5. Prepare a draft Create a local issue, pull-request, or review draft tied to the research and validation evidence already collected. ```text Prepare a pull-request draft for this contribution. Tie its claims to the recorded evidence, include the validation results, and do not post anything. ``` Draft revisions retain their exact rendered bytes and provenance. ## Interfaces and storage GitContribute stores repositories, threads, code snapshots, investigations, evidence, validation results, and contribution outcomes in SQLite. Network access is explicit; once information has been synced, corpus search and inspection work offline. ```text GitHub read APIs Local checkout | | | explicit sync / hydrate | explicit index / acquire v v +------------------------------------------------+ | Local SQLite corpus | | observations · coverage · evidence · outcomes | +------------------------+-----------------------+ | offline reads +---------+---------+ v v CLI / TUI Coding agents ``` The CLI and MCP server use the same application services and side-effect boundaries. ## CLI The CLI exposes the same workflow without requiring an MCP client: ```sh # Sync repository context and current threads gitcontribute archive sync-context owner/repo gitcontribute archive sync owner/repo # Find and inspect contribution candidates gitcontribute radar owner/repo --limit 10 gitcontribute research brief issue:owner/repo#42 # Search stored threads and indexed code gitcontribute search threads "connection timeout" --repo owner/repo gitcontribute search code "context.WithTimeout" --repo owner/repo ``` For implementation work: ```sh gitcontribute investigation start-thread issue:owner/repo#42 --json gitcontribute workspace create <investigation-id> gitcontribute validation define --kind=test --command="go test ./..." \ --working-dir=/path/to/workspace <investigation-id> gitcontribute validation run <validation-id> --kind=base --execute gitcontribute validation run <validation-id> --kind=candidate --execute gitcontribute validation compare <base-run-id> <candidate-run-id> gitcontribute readiness opportunity <opportunity-id> gitcontribute prepare pr --approach="Bound retries with context" \ --workspace <workspace-id> <opportunity-id> ``` Run `gitcontribute --help` or `gitcontribute <command> --help` for the complete command and flag reference. Most non-interactive commands accept `--json`; machine-readable output goes to stdout and progress goes to stderr. Launch the local TUI with: ```sh gitcontribute tui ``` ## MCP The MCP server advertises one unified catalog. Hosts such as Codex and Claude Code can discover large MCP catalogs with native tool search, so setup does not ask users to choose permanent capability profiles. ```sh gitcontribute setup --mode mcp --codex --token-source none --yes gitcontribute setup --mode mcp --all-clients --token-source none --yes ``` To start the stdio server directly: ```sh gitcontribute mcp serve --transport=stdio ``` Add `--read-only` to remove tools that permit network access, local writes, or execution. See [MCP catalog and composition](docs/mcp.md) for capability boundaries, snapshot recovery, resource handoffs, and common tool sequences. GitHub users are stored as first-class actors. Live discovery records identity only; profile, social-account, organization, pinned-item, repository, and contribution facts are synchronized independently. See the [actor corpus](docs/actor-corpus.md) for the data and freshness model. ## Side-effect boundaries GitContribute separates corpus reads, GitHub reads, local writes, process execution, and external mutation. | Operation | Network | Local write | Runs a process | GitHub write | | --- | :---: | :---: | :---: | :---: | | Search and inspect stored research | No | No | No | No | | Record investigations and evidence | No | Yes | No | No | | Sync or hydrate GitHub context | Yes | Yes | No | No | | Acquire and index code | Yes | Yes | `git` only | No | | Run an explicitly approved validation | No by default | Yes | Yes | No | - Corpus reads never fetch data. - Crawling and indexing never execute repository-controlled code. - Explicit validation commands run on your host with your user permissions. - GitContribute has no GitHub mutation capability. - There is no hosted corpus or product telemetry. See [Architecture](docs/architecture.md) for the complete boundary definitions. ## Documentation - [Onboarding and configuration](docs/onboarding.md) - [MCP catalog and composition](docs/mcp.md) - [Actor corpus](docs/actor-corpus.md) - [Architecture and side-effect boundaries](docs/architecture.md) - [Operational runbooks](docs/runbooks.md) - [Security policy](SECURITY.md) - [Contributing](CONTRIBUTING.md) ## Storage GitContribute follows platform conventions: | Platform | Configuration | Data | | --- | --- | --- | | Linux | `$XDG_CONFIG_HOME/gitcontribute` or `~/.config/gitcontribute` | `$XDG_DATA_HOME/gitcontribute` or `~/.local/share/gitcontribute` | | macOS | `~/Library/Application Support/gitcontribute` | `~/Library/Application Support/gitcontribute/Data` | | Windows | `%APPDATA%\gitcontribute` | `%LOCALAPPDATA%\gitcontribute\Data` | The default corpus is `gitcontribute.db` in the data directory. Run `gitcontribute metadata` or `gitcontribute doctor --json` to inspect the local setup. ## Platform support Linux and macOS are the primary development and test targets. Windows builds are tested in CI and use the standard `%APPDATA%` and `%LOCALAPPDATA%` locations. ## Development ```sh make verify go run ./cmd/gitcontribute --help ``` Before changing package boundaries or side effects, read [docs/architecture.md](docs/architecture.md).
