SeamSpec
Executable specs for AI coding agents. Build first; every seam that works gets a spec.
Status: pre-release (0.0.2). Under active development.
SeamSpec is an open-source governance layer for AI coding agents such as Claude Code, Cursor, and VS Code Copilot.
- When you and your agent get something working, SeamSpec helps turn that behavior into a small, human-approved test (an invariant).
- Approved invariants are enforced automatically: by editor hooks while the agent works, by a git pre-commit check, and in CI.
- Failed approaches are remembered as dead ends, so the agent doesn't retry them.
Most spec tools ask you to write the spec before you build. SeamSpec writes it after, from code that works, and makes sure it never silently breaks.
The name comes from Michael Feathers' seams: places where untested code can be put under test without rewriting it.
