Draft

Stop shipping AI-generated bugs.
One command runs a three-stage review on your branch — validation, spec compliance, code quality — and writes the missing tests. Free. Open-source. MIT.

The 60-second pitch

Your AI assistant just wrote 200 lines. Some of them are bugs. Some don't match your patterns. Some skip tests.

/draft:review

Three stages, one command:

• Validation — runs your tests, lints, type-checks, and surfaces real failures
• Spec compliance — checks the diff against the agreed spec, not vibes
• Code quality — flags hotspots, blast radius, and missing test coverage using a tree-sitter knowledge graph of your repo

Free. No API keys. No paid tier. No vendor lock-in. Catches the 3 bugs you missed before they hit your reviewer.

Demo coming soon — for now, watch the 8-minute walkthrough.

Install (30 seconds)

One command installs Draft into your agent. No clone, no config.

npx @drafthq/draft install <host>      # claude-code | cursor | codex | opencode

…or install the CLI once and reuse it:

npm install -g @drafthq/draft
draft install <host>
draft list                             # show every host + where it installs

Each host installs the way that host actually loads extensions — no manual steps after the command:

Host	draft install …	What it does
Claude Code	claude-code	Registers the plugin via claude plugin marketplace add + claude plugin install (user scope). Restart Claude Code.
Cursor	cursor	Copies the plugin into ~/.cursor/plugins/local/draft/, writes .cursor-plugin/plugin.json, registers draft@draft-plugins in Cursor's plugin registry, and enables it. Restart Cursor (or Developer: Reload Window).
Codex	codex	Writes ./AGENTS.md, which Codex reads automatically.
opencode	opencode	Writes ./AGENTS.md + ~/.agents/skills/draft/, both auto-discovered.

Flags: --global / --project to pick scope, --dry-run to preview, --force to overwrite, --no-graph to skip the graph-engine fetch.

Then, in Claude Code (after restarting):

/draft:init       # 5-phase codebase analysis (one-time)
/draft:review     # ← run this on every branch before you push

Run /draft for the full command map.

Other ways to install →

Claude Code — native marketplace

/plugin marketplace add drafthq/draft
/plugin install draft

Cursor — from GitHub

Cursor requires .cursor-plugin/plugin.json; the draft install cursor command also registers the plugin via the shared Claude plugin registry that Cursor reads on many builds. To add from source instead, use Settings > Rules, Skills, Subagents > Rules > New > Add from Github:

https://github.com/drafthq/draft.git

GitHub Copilot

Copilot reads a committed instructions file — copy it directly (not a draft install host):

mkdir -p .github && curl -o .github/copilot-instructions.md \
  https://raw.githubusercontent.com/drafthq/draft/main/integrations/copilot/.github/copilot-instructions.md

Gemini

curl -o .gemini.md https://raw.githubusercontent.com/drafthq/draft/main/integrations/gemini/.gemini.md

Recommended next step after install: run /draft:init to index your repo, then /draft:review on any branch with AI-generated changes. Once you've seen what it catches, explore the rest.

Built-in Code Intelligence

Draft is powered by a local knowledge graph engine (codebase-memory-mcp) that gives every command precise structural context — module boundaries, call graphs, dependencies, hotspots. It's 100% local (no API key, no SaaS), fetched during draft install (best-effort; --no-graph to skip), with first-use fetch as a fallback.

/draft:graph                                  # build / refresh the snapshot
scripts/tools/graph-impact.sh --file src/auth/login.go
# → blast radius: which files, which symbols, which tests/docs/configs

Capability	What it provides
Multi-language extraction	Tree-sitter + LSP-grade resolution across 159 languages, 100% local
Call graph	Callers/callees with confidence signals so review/bughunt can weight findings
Impact analysis	Blast-radius with file-class dimension (code/test/doc/config) — answers "what breaks if I change this?"
Cycle detection	Flags circular call dependencies before they bite
Hotspot ranking	Fan-in score so high-risk symbols get extra scrutiny
Incremental indexing	git-aware, content-based; only changed code re-indexes
Track impact memory	metadata.json.impact snapshots each completed track's blast radius — /draft:new-track flags overlap with recent work

The graph powers /draft:graph and /draft:impact, enriches /draft:bughunt and /draft:review, and is consumed by skills via core/shared/graph-query.md. The engine is installed via scripts/fetch-memory-engine.sh; the deterministic shell helpers live under scripts/tools/.

Deterministic helper tools

Skills also call into shell helpers under scripts/tools/ for mechanical work — git metadata, file classification, test-framework detection, hotspot ranking, freshness checks, ADR indexing, and live graph queries (graph-callers.sh, graph-impact.sh, hotspot-rank.sh, cycle-detect.sh, mermaid-from-graph.sh). All emit JSON or markdown, follow a uniform exit-code contract, and degrade gracefully when their input source is unavailable.

Why Draft?

AI tools are fast but unstructured. Draft applies Context-Driven Development to impose clear boundaries: explicit context, phased execution, and built-in verification, ensuring outputs remain aligned, predictable, and production-ready.

product.md       →  "Build a task manager"
tech-stack.md    →  "React, TypeScript, Tailwind"
architecture.md  →  Comprehensive: 10-section graph-primary engineering reference, Mermaid diagrams (source of truth). Mature brownfield projects with strong existing agent docs (CLAUDE.md, INVARIANTS.md, etc.) receive early Context Quality Audit, graph fidelity dashboard, and explicit Relationship + Gaps sections (no blind duplication).
.ai-context.md   →  200-400 lines: condensed from architecture.md (token-optimized AI context)
.state/          →  freshness hashes, signal classification, run memory (incremental refresh)
spec.md          →  "Add drag-and-drop reordering"
plan.md          →  "Phase 1: sortable, Phase 2: persist"

Each layer narrows the solution space. By the time AI writes code, decisions are made.

Incremental refresh: After initial setup, /draft:init refresh uses stored file hashes and signal classification to only re-analyze what changed — no full re-scan needed.
