canonical-format-checker
canonical-format-checker
panaversity / agentfactory

This skill should be used when content teaches patterns (skills, subagents, ADRs, PHRs, specifications) that have canonical sources elsewhere.

Produce a long-form, shareable markdown writeup on whether Claude has regressed on this user's work. A bundled Python script scans `~/.claude/projects/`, computes every metric, and renders a markdown skeleton with tables already filled — in ~2.5s. Claude fills a dozen short narrative placeholders and saves. Writes `./cc-canary-<YYYY-MM-DD>.md` suitable for pasting into a GitHub issue or gist.

Testing & quality46

figma-pixel-verify
figma-pixel-verify
fudesign2008 / open-skills

Measure laid-out frames of a running UI against a Figma living artifact (inventory + spec + Verify section). Use when checking pixel alignment / 对照 Figma 验收 after implementation, including light/dark or hover/variant states (switch theme and state, measure each row). Non-document UIs use a layout-probe; source-constant comparison is not a pass. Fix and remeasure in the same run until overall PASS, without asking a person. Critical unmeasured rows fail overall. The checker must exit 0; a layout probe mounts the shipping parent. An openable channel must cite a saved, non-empty screenshot file; layout-probe may say not-openable. Triggers — 「检查像素对齐」「对照 Figma 验收」「设计保真检查」「是否对齐稿面」「figma 保真检查」「暗黑模式验收」「多主题保真检查」 / verify Figma fidelity, pixel check, dark mode fidelity check, multi-theme verify. Do NOT use as the primary implementation workflow (use figma-pixel-implement) or for code→Figma.

I
infrahub-reporting-skill-gaps
infrahub-reporting-skill-gaps
opsmill / infrahub-skills

Turns friction from an Infrahub skill session into a reviewed GitHub issue about an Infrahub skill's guidance. Infrahub skills fail quietly: a missing or unclear rule does not crash, it produces extra round trips and repeated user nudges. This skill gathers evidence of that friction, checks the tracker for an existing report, works out whether the skill or the underlying product is at fault, and drafts a proposed rule change. It never files anything itself: it hands the redacted draft to infrahub-reporting-issues, which shows it to the user and gets explicit approval before any submission. TRIGGER when: accepting a friction offer, the user says "report skill friction", asks why an Infrahub skill kept failing or needed so many retries, or wants a gap in an Infrahub skill's guidance reported. DO NOT TRIGGER when: reporting a bug in Infrahub itself or any other opsmill/infrahub-* product (use infrahub-reporting-issues instead), or for ordinary Infrahub work where nothing went wrong.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
