![Backlog demo GIF using: backlog board](https://raw.githubusercontent.com/MrLesk/Backlog.md/HEAD/.github/backlog-v1.40.gif) --- > **Backlog.md** turns any folder into a **self‑contained project board** > powered by plain Markdown files and a zero‑config CLI. ## Why Backlog.md in the AI era AI agents can now produce more plausible code in an hour than you can carefully read in a day. The bottleneck is no longer writing code. It's your attention. You can't meaningfully review 15,000 generated lines in one sitting, but you can read a screenful of task specs with acceptance criteria before any code exists, and push back while a misunderstanding is still one sentence, not a rebuilt feature. Backlog.md structures agent work around **three review checkpoints**: 1. **Review the spec:** the agent decomposes your idea into tasks with descriptions, acceptance criteria, and milestones before implementation starts. 2. **Review the plan:** the agent researches your codebase and writes its implementation plan into the task. Approve it or steer before any code is written. 3. **Review the code:** one task = one context window = one PR. Diffs stay a size a human can actually read. Afterwards, the completed tasks remain in Git as a permanent record of what was attempted and why, legible to you, your team, and the next agent. **Dogfooded:** nearly all of Backlog.md's own code is written by AI agents working through Backlog.md itself. The full task ledger lives in this repo's [backlog folder](https://github.com/MrLesk/Backlog.md/blob/HEAD/backlog/tasks). 📺 **See it in action:** [Devoxx Belgium 2025](https://www.youtube.com/watch?v=LSoDQU_9MMA) · [AI Engineer Code Summit 2025](https://www.youtube.com/watch?v=zMXKhhwiCIc) ## Features * 🤖 **AI-ready** -- works with Claude Code, Gemini CLI, Codex, Kiro & any other MCP or CLI compatible AI assistant * 📝 **Markdown-native tasks** -- every task is a plain `.md` file in your repo * ✅ **Acceptance criteria & Definition of Done** -- verifiable scope per task, plus a reusable DoD checklist for every new task * 🎯 **Milestones & dependencies** -- structure bigger efforts and make execution order reviewable, with task detail showing what a task waits on and what waits on it * 📊 **Terminal Kanban** -- `backlog board` paints a live board in your shell; `backlog board export` creates shareable markdown reports * 🌐 **Web UI** -- `backlog browser` serves a local Kanban board with drag-and-drop and task editing forms * 🔍 **Search** -- fuzzy search across tasks, docs & decisions with `backlog search` * 🔒 **Local-first** -- no server, no account, no telemetry; tasks are plain files in your repo, and remote Git operations are optional * 💻 Cross-platform (macOS, Linux, Windows) · 🆓 MIT-licensed & open-source --- ## Getting started Getting started ```bash # Install npm i -g backlog.md # or: bun add -g backlog.md # or: brew install backlog-md # or: nix run github:MrLesk/Backlog.md # Initialize in any Git repo backlog init "My Awesome Project" # Or initialize without Git for local/non-code projects backlog init "Personal Planning" --no-git ``` > [!TIP] > **Trying it without installing?** Use the full package name: `npx backlog.md init "My Project"`, `npx backlog.md board`. ### Run with Nix Run Backlog.md directly from the repository flake: ```bash nix run github:MrLesk/Backlog.md -- --version ``` Or install the named package into your Nix profile: ```bash nix profile install github:MrLesk/Backlog.md#backlog-md ``` The Nix flake supports `x86_64-linux`, `aarch64-linux`, and `aarch64-darwin`. The x86_64 Linux package uses [Bun's unified x64 runtime](https://bun.com/docs/installation#cpu-requirements), with an SSE4.2 minimum and automatic CPU-specific paths. Pre-AVX2 compatibility is checked under Ivy Bridge emulation. Intel macOS users can use the npm, Bun, or Homebrew installation instead. The init wizard will ask how you want to connect AI tools: - **CLI instructions** (recommended): creates a short instruction file that tells agents to run `backlog instructions overview`. - **MCP connector**: optionally auto-configures Claude Code, Codex, Gemini CLI, Kiro or Cursor for teams that prefer MCP. - **Skip**: no AI setup; use Backlog.md purely as a task manager. For Cursor with CLI instructions, select AGENTS.md or pass `--agent-instructions cursor`; both use the same AGENTS.md target. Backlog.md preserves existing AGENTS.md content and does not migrate or remove unrelated user-managed `.cursor/rules` files. Everything is stored as human-readable Markdown in a project-local backlog folder such as `backlog/`, `.backlog/`, or a custom project-relative path configured through `backlog.config.yml` (e.g. `backlog_directory: my-backlog`). Task IDs use a configurable prefix (`backlog init --task-prefix`): the default produces `TASK-1`-style IDs, while this repository uses `back`, so examples below show `BACK-1`-style IDs. Git is optional: `backlog init --no-git` creates a filesystem-only project. > [!TIP] > **Want an architecture diagram of your repo, kept up to date automatically?** See the [Backlog.md + Groma.md integration](#groma-md) below. --- ## Working with AI agents This is the recommended flow for Claude Code, Codex, Gemini CLI, Kiro and similar tools, following the **spec‑driven AI development** approach. After running `backlog init`, agents should start by running `backlog instructions overview`. Work in this loop: **Step 1: Describe your idea.** Tell the agent what you want to build and ask it to split the work into small tasks with clear descriptions and acceptance criteria. **🤖 Ask your AI Agent:** > I want to add a search feature to the web view that searches tasks, docs, and decisions. Please decompose this into small Backlog.md tasks. > [!NOTE] > **Review checkpoint #1:** read the task descriptions and acceptance criteria. **Step 2: One task at a time.** Work on a single task per agent session, one PR per task. Good task splitting means each session can work independently without conflicts. Make sure each task is small enough to complete in a single conversation. You want to avoid running out of context window. **Step 3: Plan before coding.** Ask the agent to research and write an implementation plan in the task. Do this right before implementation so the plan reflects the current state of the codebase. **🤖 Ask your AI Agent:** > Work on BACK-10 only. Research the codebase and write an implementation plan in the task. Wait for my approval before coding. > [!NOTE] > **Review checkpoint #2:** read the plan. Does the approach make sense? Approve it or ask the agent to revise. **Step 4: Implement and verify.** Let the agent implement the task. > [!NOTE] > **Review checkpoint #3:** review the code, run tests, check linting, and verify the results match your expectations. Mark verified work Done (or the configured final status). During periodic cleanup, `backlog task archive` moves it off the board; the same command takes canceled, duplicate, or invalid work off the board at any time. An archived task keeps its ID, record, and dependency links, stays readable with `backlog task view`, and is read-only. `backlog task restore` brings an archived task back to the board with the same ID. To remove a task for good, archive it and then run `backlog task delete`, which releases its ID once no other branch or worktree still holds the task. If the output is not good enough: clear the plan/notes/final summary, refine the task description and acceptance criteria, and run the task again in a fresh session. --- ## Working without AI agents Use Backlog.md as a standalone task manager from the terminal or browser. ```bash # Create and refine tasks backlog task create "Render markdown as kanban" backlog task edit BACK-1 -d "Detailed context" --ac "Clear acceptance criteria" # Track work backlog task list -s "To Do" backlog task list --json | jq '.tasks[] | .id' backlog task edit BACK-1 --comment "Can we split the UI work into a separate PR?" --comment-author @sara backlog search "kanban" backlog board # Work visually in the browser backlog browser ``` You can switch between AI-assisted and manual workflows at any time; both operate on the same Markdown task files. Just prefer Backlog.md commands (CLI/MCP/Web) over hand-editing task files, so field types and metadata stay consistent. Read commands support stable, versioned JSON for scripts and integrations. Use `--json` with `task list`, `task view`, the `task ` shorthand, and `search`. JSON mode is noninteractive and keeps successful stdout machine-readable. Add `--watch` to `task list --json` for an initial full list followed by changed full replacements, using the exact same JSON format. Read successive complete JSON values; each response replaces the previous list. **Learn more:** [CLI reference](https://github.com/MrLesk/Backlog.md/blob/HEAD/CLI-INSTRUCTIONS.md) | [Advanced configuration](https://github.com/MrLesk/Backlog.md/blob/HEAD/ADVANCED-CONFIG.md) --- ## 🗺️ Backlog.md + Groma.md Backlog.md keeps the spec, the plan and the code reviewable. [Groma.md](https://groma.md) adds the architecture: it scans your repository into a C4 map that you or your coding agent curate, stored next to your code as an [Open Knowledge Format 0.2](https://github.com/GoogleCloudPlatform/open-knowledge-format/blob/main/SPEC.md) bundle. It reads your Backlog.md tasks, so the two work well together: Backlog.md's own architecture in Groma.md: Backlog.md tasks pinned to the components they touch, with one task selected and its acceptance criteria open * 📍 **Tasks on the map** -- every task is pinned to the components it touches, so you see where the work lands in your system, not only in a list * 👀 **Who is doing what** -- with several agents at work, the map shows where each one is busy * 🔍 **Review a task by its architecture** -- select a task to highlight the components it touches and inspect its changes without leaving the map * 📦 **Open Knowledge Format 0.2** -- one Markdown document per element, so the map stays portable and readable without Groma.md * 📝 **Still plain files** -- both run locally, need no account, and keep everything as Markdown in your repo Groma.md is a separate install, and Backlog.md works fine without it. To add the map to a repo that already uses Backlog.md: ```bash npm i -g groma.md groma web ``` Backlog.md uses it on itself: every push to main updates its map, and every pull request gets a comment showing what it changes in the architecture. 👉 **[Get started at groma.md](https://groma.md)** 🗺️ **[Explore Backlog.md's own architecture, live](https://mrlesk.github.io/Backlog.md/architecture/auto/)** --- ## Web Interface Web Interface Launch a web interface for visual task management on the local machine. The server listens on `127.0.0.1` and is not reachable from other devices on the LAN or VPN: ```bash # Start the web server (opens browser automatically) backlog browser # Custom port backlog browser --port 8080 # Don't open browser automatically backlog browser --no-open ``` **Features:** - Interactive Kanban board with drag-and-drop - Multi-select cards to move several tasks to one column - Task creation and editing with forms - Interactive acceptance criteria editor with checklists - Real-time updates across all views - Responsive design for desktop and mobile - Task archiving with confirmation dialogs - Seamless CLI integration - all changes sync with markdown files ![Web Interface Screenshot](https://raw.githubusercontent.com/MrLesk/Backlog.md/HEAD/.github/web.jpeg) To keep the Web UI running as an auto-starting local service, see [Running Backlog.md as a Service](https://github.com/MrLesk/Backlog.md/blob/HEAD/backlog/docs/doc-003%20-%20Running-Backlog-Browser-as-a-Service.md). --- ## 🔧 MCP Integration (Model Context Protocol) CLI instructions are the default AI setup. MCP remains supported for AI coding assistants like Claude Code, Codex, Gemini CLI and Kiro when you explicitly prefer an MCP connector. You can run `backlog init` (even if you already initialized Backlog.md) and choose MCP integration, or follow the manual steps below. ### Client guides
Claude Code ```bash claude mcp add backlog --scope user -- backlog mcp start ```
Codex ```bash codex mcp add backlog -- backlog mcp start ```
Gemini CLI ```bash gemini mcp add backlog -s user backlog mcp start ```
Kiro ```bash kiro-cli mcp add --scope global --name backlog --command backlog --args mcp,start ```
Cursor / other MCP clients Use the manual JSON config below in your client's MCP settings.
Use the shared `backlog` server name everywhere. The server finds the active project from your client's MCP roots, and re-resolves when you switch workspace or worktree. A single user-scope server covers every repo.
Manual config ```json { "mcpServers": { "backlog": { "command": "backlog", "args": ["mcp", "start"], "env": { "BACKLOG_CWD": "/absolute/path/to/your/project" } } } } ``` Set `BACKLOG_CWD` to pin the server to one project and stop workspace following. Use it to always target the same backlog, or when your client can't report MCP roots. If your IDE supports custom args but not env vars, you can also use `["mcp", "start", "--cwd", "/absolute/path/to/your/project"]`. Until the server finds an initialized project, it serves `backlog://init-required`.
> [!IMPORTANT] > When adding the MCP server manually, add a short instruction to your CLAUDE.md/AGENTS.md files telling agents to read `backlog://workflow/overview`. > This step is not required when using `backlog init` as it adds these instructions automatically. > For CLI-based setups, use `backlog instructions overview` to fetch the current workflow guidance. Once connected, agents can read the Backlog.md workflow instructions via `backlog://workflow/overview`, with detailed guides at `backlog://workflow/task-creation`, `backlog://workflow/task-execution`, and `backlog://workflow/task-finalization`. Use `/mcp` command in your AI tool (Claude Code, Codex, Kiro) to verify if the connection is working. --- ## CLI Reference CLI reference Full command reference covering task management, search, board, docs, decisions, and more: **[CLI-INSTRUCTIONS.md](https://github.com/MrLesk/Backlog.md/blob/HEAD/CLI-INSTRUCTIONS.md)** Quick examples: `backlog`, `backlog instructions`, `backlog task create`, `backlog task list`, `backlog task edit`, `backlog milestone add`, `backlog milestone rename`, `backlog milestone remove`, `backlog search`, `backlog board`, `backlog browser`. Full help: `backlog --help` --- ## Configuration Configuration Backlog.md works with zero configuration. Settings merge from CLI flags, then the project config file (`backlog.config.yml` when present, otherwise `backlog/config.yml` or `.backlog/config.yml`), then built‑in defaults. Run `backlog config` with no arguments to launch the interactive wizard (the same experience triggered from `backlog init` advanced setup). It walks through cross-branch accuracy (`checkActiveBranches`, `remoteOperations`, `activeBranchDays`), Git workflow (`autoCommit`, `bypassGitHooks`), ID formatting (`zeroPaddedIds`), editor integration (`defaultEditor`), Definition of Done defaults, and Web UI defaults (`defaultPort`, `autoOpenBrowser`). Skipping the wizard applies the safe built-in defaults, and rerunning `backlog init` or `backlog config` pre-populates prompts with your current values. For filesystem-only projects (`backlog init --no-git`), the saved config forces `checkActiveBranches=false`, `remoteOperations=false`, and `autoCommit=false` so CLI, Web, and MCP local-file workflows do not depend on a Git repository. ### Definition of Done defaults Set project-wide DoD items with `backlog config` (or during `backlog init` advanced setup), in the Web UI (Settings → Definition of Done Defaults), or by editing the project config file directly: ```yaml definition_of_done: - Tests pass - Documentation updated - No regressions introduced ``` When a project uses root config discovery, edit `backlog.config.yml` instead of `backlog/config.yml`. These items are added to every new task by default. You can add more on create with `--dod`, or disable defaults per task with `--no-dod-defaults`. For the full configuration reference (all options, default values, commands, and detailed notes), see **[ADVANCED-CONFIG.md](https://github.com/MrLesk/Backlog.md/blob/HEAD/ADVANCED-CONFIG.md)**. --- ## Troubleshooting ### Apple Silicon (macOS) On M-series Macs, `backlog` can fail with `illegal hardware instruction` or `Binary package not installed for darwin-...` when Node, Bun, or Homebrew run under Rosetta (x64 emulation) and install the Intel binary instead of the arm64 one — or the other way around. The launcher runs whichever darwin variant (arm64 or x64) is actually installed, but a clean native-arch install is the reliable fix. Check what your tools report: ```bash uname -m # arm64 = Apple Silicon hardware; x86_64 = Intel or a Rosetta shell node -p process.arch # architecture of your Node/Bun runtime sysctl -in sysctl.proc_translated # 1 = current shell runs under Rosetta which brew # /opt/homebrew = arm64 brew, /usr/local = Intel brew ``` If the architectures disagree, reinstall with the native one: ```bash # Homebrew: make sure `which brew` prints /opt/homebrew, then brew reinstall backlog-md # npm arch -arm64 npm i -g backlog.md # Bun arch -arm64 bun add -g backlog.md ``` Running an x64 Node under Rosetta on purpose also works: `backlog` falls back to whichever `backlog.md-darwin-*` package is present. --- ## 📺 Talks & Community Watch Backlog.md in action: - **Devoxx Belgium 2025**: [the spec-driven agent workflow behind Backlog.md, live on stage](https://www.youtube.com/watch?v=LSoDQU_9MMA) - **AI Engineer Code Summit 2025**: [Backlog.md: task management for AI agents](https://www.youtube.com/watch?v=zMXKhhwiCIc) - Slides from these and more talks: [mrlesk.com/talks](https://mrlesk.com/talks) ### Community tools - **[vscode-backlog-md](https://marketplace.visualstudio.com/items?itemName=ysamlan.vscode-backlog-md)** - VS Code extension with issues panel, kanban view, and editing.
