Architectural guidance for changes to the PostHog Wizard: program and framework boundaries, agent routing, gateway admission, security, and TUI state. Read before structural changes, then load the relevant procedural skill.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Wizard development

Ask who owns the concern and what they should need to understand to change it.
Product knowledge belongs behind typed configuration boundaries; runner and UI
infrastructure should consume those boundaries.

| Concern                                               | Owner                                                                                                                                                                           |

How to install

The exact contents, by fingerprint

mdr add posthog/wizard/wizard-development@sha256:0652a57362ed772e

The line at the top of this page pins the label v2.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
