pp-mixlayer
Privacy-first Mixlayer CLI for OpenAI-compatible chat, local PII redaction and vaulting, reasoning-aware model ladders, live model catalog refresh, and ledger-backed cost proofs.
Why this skill is useful
Adds multiple executable commands for privacy-focused data handling and model interaction that are not available in public documentation.
What it needs
Requires mixlayer-pp-cli installed locally. About 7k tokens when loaded. Last updated 2026-08-06. 1,890 stars on the source repository.
What this skill does
Mixlayer — Printing Press CLI Prerequisites: Install the CLI This skill drives the mixlayer-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: mixlayer-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead: If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. Use this skill for Mixlayer chat completions, privacy-safe frontier prompts, model-rung comparisons, reasoning ledger search, and local cost analysis. Unique Capabilities These capabilities aren't available in any other tool for this API. shield ingest — Split large CSV/text inputs into deterministic tranches, redact each tranche through one shared local vault, and reassemble a masked corpus with a manifest. shield ask — Redact local data, run an outbound PII tripwire, send only the masked payload to a frontier model, rehydrate the answer locally, and save a privacy receipt. shield scan — Detect high-risk PII locally with CI-friendly exit codes and no upstream model call. shield redact — Write a masked copy of a file and populate the local token-to-value vault with stable pseudonyms. shield restructure — Drop columns, bucket numeric values, and coarsen dates to reduce re-identification risk before prompting. vault — List, rehydrate, rotate, or purge the local reversible pseudonym vault without sending values upstream. …
