Chalk Labs
Need help deploying pegrex-legacy?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/ovoxnox-pegrex-legacy
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

# legacy modernization
- `modernize.modernize("prog.cob")` -> emitted Python + cross-language
equivalence certificate. Executes; refusal carries a counterexample.
- `py2cobol.round_trip("f.py")` proves contract identity Python->COBOL.
- Identifiers canonicalize UPPERCASE in legacy frontends (documented
convention). Rust/Go targets refuse to claim equivalence.From ovoxnox/pegrex, MIT.
