Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Make Claude Code follow a real engineering workflow — Explore → Specify → Plan → TDD → Audit → Commit — with guardrails that test-first, audit to a quality score, and block secrets + destructive commands automatically.
Most Claude Code setups add more agents. claude-base adds discipline and safety: per-file rules, hooks, and an anti-drift CI gate. One install, auto-detects your stack — and it learns from your mistakes across every project so you stop repeating them.
claude-base install tour
_A real curl | bash install + claude-base init scaffolding the foundation into a project — start to finish._
Requires: the Claude Code CLI (the claude command), plus git and jq on your PATH (claude-base init reads JSON manifests with jq).
# 1. Install the foundation (clones to ~/.local/share/claude-base, symlinks to ~/.local/bin)
curl -fsSL https://raw.githubusercontent.com/christopherlouet/claude-base/main/install.sh | bash
claude-base version # ✓ should print: claude-base v5.0.0
# 2. Install into a project (auto-detects the stack, picks the right preset)
claude-base init --preset nextjs ./my-app
# or just: claude-base init ./existing-project (interactive, auto-detects)
# ✓ prints a summary of the .claude/ files written into the project
# 3. Open Claude Code in the project and run the canonical workflow
cd ./my-app && claude
> /work:work-flow-feature "add a /counter route with optimistic UI"That last command chains the 6 phases automatically: Explore → Specify → Plan → TDD → Audit → Commit. Each phase has dedicated slash commands you can also drive manually.
| You are... | This helps... | Skip it if... |
|---|---|---|
| Solo dev shipping side-projects with Claude Code | preset gives you stack + workflow rigor in 30s ; no copy-pasting prompts between sessions | you barely use Claude Code yet — start with the official docs first |
| Team lead wanting consistent Claude Code outputs across a codebase | enforces TDD + audit-loop gates in shared .claude/ config, anti-drift counters CI-gated | your team has already built bespoke prompts you're happy with |
| Educator / mentor | the 6-phase workflow is named, teachable, and the audit-loop produces a quality score | you only need ad-hoc Claude Code use |
| Returning user who tried Claude Code, found it too freeform | the dispatcher CLI stays small and learnable, and the foundation is fully reversible (claude-base uninstall) | you prefer raw .claude/ files without a foundation layer |
You don't have to learn the <!-- count:commands -->106<!-- /count --> commands. The core loop is six slash-commands — one per phase: /work:work-explore, /work:work-specify, /work:work-plan, /dev:dev-tdd, /qa:qa-loop, /work:work-pr. The rest are domain-specific (CI, a11y, payment, GDPR, etc.) and either auto-trigger via path rules or stay one slash away when relevant.
claude-base is the opinionated discipline layer for Claude Code — it doesn't compete with the tools below, it composes with them:
specify / plan / tasks / implement across 30+ agents; claude-base adds what it doesn't: an Explore phase, enforced TDD, the audit-fix loop, path-specific rules, and hooks — Claude-Code-native. Use both: spec-kit for the primitives, claude-base for the discipline.Full positioning — comparison tables, the curation engine, and where it's heading — in docs/POSITIONING.md.
A default install ships the core only. The horizontal activity domains (biz,legal,growth) and the stack/thematic domains (nextjs,flutter,iac,observability, …) are opt-in modules (claude-base add <module>) — runclaude-base modulesto list all 15. A fresh project gets the smaller core slice. Seespecs/horizontal-pure-modules/.

Learns across projects. A personal, human-gated lessons referential: after a hard-won fix or a correction, claude-base proposes a generalized, sanitized one-line lesson and — on your confirmation — stores it in your own ~/.claude/rules/lessons.md, which Claude Code loads into every project. A mistake made once stops recurring everywhere; run /lessons --bootstrap to seed it from what you already learned. The lessons stay yours — never committed to any repo. How it works →

After install, you cd ./my-app && claude and the foundation drives the workflow (the GIF at the top of this page is the real install, recorded in an isolated Docker container — reproducible, scaffolding under website/demo/):
> /work:work-flow-feature "add a /counter route with optimistic UI"
[work-explore] Scans app/, hooks/, lib/ → detects the project shape
[work-specify] Drafts user stories + acceptance criteria
[work-plan] Lists the files to touch + identifies risks
[dev-tdd] RED → GREEN → REFACTOR cycle, tests before code
[qa-loop] Audit + auto-fix until target score (default ≥ 90)
[work-pr] Branch, commit, push, open the PROne command chains the 6 phases. Each phase is also runnable on its own (/work:work-explore, /dev:dev-tdd, etc.) if you prefer manual control.
curl -fsSL https://raw.githubusercontent.com/christopherlouet/claude-base/main/install.sh | bashThis clones the foundation to ~/.local/share/claude-base and symlinks the dispatcher into ~/.local/bin/claude-base. The installer never runs as root, never modifies your shell rc files, and needs only git to run (the next step, claude-base init, additionally needs jq — see Requirements). After install:
claude-base init --preset fastapi ./my-api # Python backend
claude-base init --preset nextjs ./my-web-app # Next.js fullstack
claude-base init --simple ./my-project # Foundation only, no preset
claude-base preset list # Discover available presets
claude-base help # All commandsTo update the foundation later:
curl -fsSL https://raw.githubusercontent.com/christopherlouet/claude-base/main/install.sh | bash -s -- --update#### Pinning to a release (reproducible installs)
The one-liner above tracks the moving main tip. To install a specific, tested release instead, pass --ref <tag> — still a single line:
curl -fsSL https://raw.githubusercontent.com/christopherlouet/claude-base/main/install.sh | bash -s -- --ref v5.0.0A pinned install stays pinned across --update (it never silently jumps to main). To move it to another release, pass --ref <newtag>; to return to the latest main, pass --ref main.
#### Verify before executing (supply-chain conscious)
Piping any script straight into your shell runs it unverified — our own security.md rule says to download → verify → execute, and a hook in this repo blocks curl … | sh in agent sessions. Each tagged release publishes a SHA256SUMS asset, so you can honor that on install:
TAG=v5.0.0
curl -fsSL "https://raw.githubusercontent.com/christopherlouet/claude-base/$TAG/install.sh" -o install.sh
curl -fsSL "https://github.com/christopherlouet/claude-base/releases/download/$TAG/SHA256SUMS" -o SHA256SUMS
sha256sum --check --ignore-missing SHA256SUMS # must print: install.sh: OK
bash install.sh --ref "$TAG"Fetch install.sh from the same tag as the checksum (/$TAG/, not /main/) — the published SHA256SUMS covers the tagged script, not the moving tip.
If ~/.local/bin is not on your PATH, add it (most modern distros already do):
export PATH="$HOME/.local/bin:$PATH" # add to ~/.bashrc or ~/.zshrcgit clone https://github.com/christopherlouet/claude-base.git
cd claude-base
# Install in an existing project (in-repo dispatcher — no PATH install yet)
./bin/claude-base init --simple /path/to/your/project
# Full install with CI/CD, hooks, Docker
./bin/claude-base init --all /path/to/your/project# Copy the Claude configuration directly
cp -r claude-base/.claude your-project/
cp claude-base/CLAUDE.md your-project/
# Optional
cp claude-base/.mcp.json your-project/
cp claude-base/.github your-project/ -rThe commands above install and update claude-base — they do not touch the underlying Claude Code CLI. If you installed Claude Code through Homebrew or WinGet, you can opt into background upgrades by exporting CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE=1 in your shell. This has no effect on the curl one-liner install of claude-base, and no effect if you installed Claude Code through any other channel. Available in Claude Code 2.1.129+.

The fastest way in is the built-in orchestrator — or run the six phases yourself:
/assistant # guided: explains the workflow and suggests the next command
/assistant-auto "..." # automatic: routes your request to the right workflow# 1. Explore the existing system
/work:work-explore the authentication system
# 2. Specify the feature (User Stories + acceptance criteria)
/work:work-specify add OAuth2 Google sign-in
# 3. Plan the implementation
/work:work-plan OAuth2 Google
# 4. Implement in TDD (tests BEFORE the code)
/dev:dev-tdd OAuth2 authentication flow
# 5. Audit + fix loop (score 90 required)
/qa:qa-loop "score 90"
# 6. Open the PR
/work:work-pr OAuth2 Google authenticationThe shape is identical for any stack — swap the arguments (e.g. /dev:dev-tdd UserProfileScreen with BLoC + widget tests for a Flutter screen). The single /work:work-flow-feature "..." command chains all six phases for you.

Pass --clean to wipe-and-replace (a backup is created first). update also flags a stack pivot: if your project has outgrown its recorded preset (e.g. a Vite SPA that grew into Next.js), it prints a non-blocking notice pointing at claude-base update --preset <name>; --detect-only reports that check (Diverges: yes/no) without updating anything.
The foundation follows Semantic Versioning. Each release is tagged vX.Y.Z and shipped with a GitHub Release containing the relevant CHANGELOG excerpt. Pin via git checkout vX.Y.Z in ~/.local/share/claude-base if you need reproducible installs. Behaviour-breaking changes between minor versions are explicitly called out in the CHANGELOG under ### Breaking.
