What is IntentGuard?

IntentGuard is an open-source, self-hosted GitHub Action that automatically reviews pull requests against linked Linear issues and sprint context. It uses AI to classify PRs as ALIGNED, MISALIGNED, or UNCLEAR, helping AI-native engineering teams ensure code changes stay on track with project intent.

Key Features
  • Reviews PRs against linked Linear issues and sprint context
  • Classifies PRs as ALIGNED, MISALIGNED, or UNCLEAR with reasoning
  • Self-hosted via GitHub Actions, no data sent externally except to LLM provider
  • Code review agent that analyzes git diffs and posts findings (read-only)
  • Documentation sync agent that updates Markdown docs to match code via PRs (docs-only, never auto-merges)
  • Autonomous QA testing agent that understands product from code and executes end-to-end flows with backend assertions
  • Reads repository structure without model calls (grep+find) to extract routes, services, and entities
  • Derives prioritized end-to-end business flows from code analysis
  • Runs each flow as an agent loop with Playwright browser driving and backend API assertions via token reuse
  • Free audit of codebase and knowledge base
  • Agentic code generation and refactoring
  • Senior engineer review on every PR
Pros
  • Open-source and self-hosted, full data control
  • Direct integration with GitHub and Linear
  • Requires no manual test writing — QA agent derives flows from code
  • Deep autonomous testing with frontend and backend assertions
  • Open source and self-hosted, no vendor lock-in
  • Automatically understands application logic from code, not just UI
  • Pay only for shipped code, no retainer
  • Free audit with no obligation
Cons
  • Requires LLM API key (Anthropic) for live use
  • Only supports Linear issue tracking (no Jira, Notion, etc.)
  • Requires setup of multiple dependencies (Node.js, Playwright, CLI tools)
  • Agent-based testing can be non-deterministic and slower than scripted tests
  • Requires manual setup of environment and dependencies
  • Not a hosted SaaS; operator must manage infrastructure
  • Not ideal for greenfield projects without scoping
  • Requires upfront deposit for work
Best For
  • Engineering teams using Linear and GitHub
  • Teams using AI coding agents like Copilot or Cursor
  • Developers and teams wanting automated, continuous code review and testing
  • QA engineers looking to reduce manual test script maintenance
  • Development teams needing automated end-to-end QA without writing test scripts
  • Projects with complex business flows where UI-only testing misses backend state bugs
  • Non-technical founders
  • Startups with overflowing backlogs
