Fillbyte creates software that gives people and development teams more capability with less friction. We build focused products, open-source developer infrastructure, and agent-native tools across the software lifecycle.
Our work is designed to be useful in real systems: clear in scope, composable with existing tools, explicit about trust boundaries, and backed by reproducible evidence.
| Project | Role |
|---|---|
| Fillbyte Skills | Production-grade agent skills, Codex plugins, MCP servers, and developer tools for research, architecture, implementation, testing, security, operations, and delivery. |
| Surface Audit | Deterministic security smoke tests for preview, staging, and pre-deploy web surfaces. |
| docsmoke | Executable documentation tests for Markdown examples, CI pipelines, and reusable GitHub Actions. |
- Solve a specific problem before adding abstraction.
- Prefer interoperable, inspectable building blocks over closed workflows.
- Treat tests, documentation, security boundaries, and release evidence as product features.
- State uncertainty and limitations instead of turning incomplete evidence into confidence.
- Keep open-source interfaces useful beyond any single product, platform, vendor, or framework.
