v0.6.20

Improvements

• Early workflow input validation: When running a workflow locally, Libretto now validates the workflow's input schema against the provided --params before opening a browser session. Invalid params produce a clear error immediately, without launching the browser first.

• npx libretto as the standard invocation: All documentation, README files, agent skill files, and scaffolded templates now use npx libretto <command> instead of a bare libretto command. The global install.sh installer has been removed. Installation is now purely through the local package (npm install libretto), with commands run via npx or the equivalent for pnpm, yarn, and bun projects.

• Simplified version mismatch warnings: The version mismatch warning now focuses on skill-vs-package mismatches and tells users to run libretto setup to fix them, rather than listing separate update instructions for the global CLI, local package, and skill files.

• libretto update uses project package manager: The update command now detects the project's package manager (npm, pnpm, yarn, or bun) and runs the appropriate install command for that tool instead of running the install.sh global installer script.

Fixes

• Billing price formatting: Escaped dollar signs in the billing docs so Mintlify renders the per-second and per-hour prices as bold text rather than inline math.
