Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Spec Execution
Overview
Executes a feature specification through 6 iterative phases with quality-gated convergence. Each phase builds on the previous, with improvement cycles triggered when quality falls below threshold.
Six Phases
Phase 1: Implementation
- Read specification for requirements and architecture
- Implement each requirement following project conventions
- Add type definitions and JSDoc documentation
- Implement error handling for all failure modes
Phase 2: Test Writing
- Write unit tests for each module/function
- Write integration tests for API boundaries
- Cover all acceptance criteria from the specification
- Test edge cases and error paths
Phase 3: Code Review
- Verify all requirements are implemented
- Check acceptance criteria are tested
- Review architecture adherence
- Assess code quality
Phase 4: Iterative Improvement
- Address review findings
- Fix failing tests
- Resolve architecture deviations
- Re-verify quality (convergence loop, max 3 cycles)
Phase 5: Atomic Commit
- Group changes into logical atomic commits
- Descriptive messages following project conventions
- Separate production, test, and config changes
- Include specification reference
Phase 6: Progress Tracking
- Requirement completion percentage
- Test coverage summary
- Quality score report
- Remaining work identification
Quality Gate
Quality threshold defaults to 80. If not met after max improvement cycles, a human breakpoint is triggered for review.
