Skylos
Code checks that show their work.
What Is Skylos?
Skylos is an open-source (Apache-2.0) CLI and pull-request gate for Python
projects that runs without an account. skylos . finds dead code: unused
functions, classes, imports and empty files. Add -a to check security bugs,
hard-coded secrets, vulnerable dependencies, code quality and AI-code
mistakes. Findings include source locations and supporting analysis;
skylos done checks whether a branch, often a coding agent's, is ready to
merge.
It is built for:
- Teams merging pull requests from AI coding agents such as Claude Code,
Codex and Cursor.
skylos doneruns your tests and flags deleted or skipped tests, loosened CI test steps, silenced lint or type checks, and test-only special cases. - Python maintainers who want framework-aware dead-code, security and secrets checks. Python has the deepest coverage; other languages are listed under Language Support.
pip install skylos
skylos . # find dead code
skylos . -a # add security, secrets, quality, dependency and AI-code checks
skylos done --base main # is this branch finished? runs your tests, compares with main
