Build, debug, or publish an OpenClacky extension — scaffold a new one from an idea, fix a broken/invisible panel/api/skill/agent, or ship it to the marketplace. Trigger on create/start extension, plugin, panel, ext verify error, "won't load", "not showing up", publish/ship/unpublish an extension.
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
# Extension Development Use this skill to guide the workflow, not as a second API manual. The online references below own the detailed contracts, examples, and reload behavior. The local engineering checks below remain mandatory even when those references cannot be fetched. ## Before designing or editing 1. Identify what the user wants and the smallest capability set that can provide it. Check existing host services and shared panels before building a replacement. 2. For behavior-only discussion, apply **Engineering checks** without enumerating APIs. Before specifying or implementing an interface, choose its one matching capability reference below; read the overview when container/scaffold/reload behavior is relevant. Reuse verified text still in context. For a named interface, obey the system prompt's strict lookup budget and stop as unverified when it is exhausted. Use the article's contract/examples, not the documentation site's navigation, styles, or scripts. If the user declined a fallback, request only the missing source and never ask again. 3. Confirm the proposed behavior, affected files, and visible result with the user …

mdr add clacky-ai/openclacky/ext-develop@sha256:7576610e953edd85The line at the top of this page pins the label git:20260928.5326d06, 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.
