ai-builder-kit
A collection of skills, plugins, and hooks for AI coding agents. Works as a Claude Code plugin marketplace, a Codex plugin marketplace, and a plain skills repo for npx skills. Every skill is a portable SKILL.md, so the same folder works in Claude Code, Codex, and any agent that follows the Agent Skills spec.

One source of truth: every channel reads the same skills/ folder, and the hook plugin pulls its skill in through a symlink instead of a copy.
Available Skills
| Skill | Last Modified | Description |
|---|
| ai-knowledge-harvester | 2026-04-12 | Harvest AI docs, prompt logs and agent configs from repos or pasted AI exports into a private knowledge repo with a project-first taxonomy |
| branded-pptx | 2026-10-25 | Create branded PowerPoint decks from a template: analyzes themes, slide masters and layouts (shape dimensions, text capacity, visual data), then generates slides that match, in timestamped run folders. Requires: the pptx skill, uv |
| chat-conversation-logger | 2026-05-24 | Log Claude.ai chat conversations as prompt-log-YYYY-MM-DD-{N}-{slug}.md files with verbatim prompts, attachment metadata and a per-turn tool record |
| competing-pr-triage | 2026-04-11 | Compare two PRs or branches that different agents produced for the same goal and recommend one, with a per-requirement verdict table, a scope audit and a follow-up plan |
| conversation-logger | 2026-05-24 | Log Claude Code and Codex sessions as prompt-log-YYYY-MM-DD-{N}-{slug}.md files. The stage counter {N} keeps a folder listing in chronological order, and a new day starts a new file |
| drawio | 2026-04-27 | Generate .drawio XML diagrams in Jack's brand style (swimlane frames, 4-color semantic palette, cylinders for data stores, orthogonal edges, dashed lines only for responses). Multiple-choice interview first, then a render-view-fix loop with versioned iterations. Ships worked examples and an evals harness |
| excalidraw | 2026-09-13 | Generate .excalidraw diagrams in Jack's brand style (hand-drawn roughness, Nunito, 7-color semantic palette, frames for grouping) with a mandatory render-view-fix loop. Ships six worked examples with PNG previews and an evals harness. Requires: uv plus a one-time uv run --with playwright playwright install chromium |
| hlx-admin-api-executor | 2026-10-25 | AEM Edge Delivery Services Admin API executor: plan the calls, run one request at a time with human review, and log every request and response. Soft guardrails only; the guarded plugin below enforces them |
| jack-git-commit | 2026-11-06 | Conventional Commits with traceable metadata footers (Goal, Step, Worker, Skill, Tools), so git log works as a queryable work ledger. Pushes when done unless the project says not to |
| playwright-demo-video | 2026-06-11 | Generate polished demo MP4s from Playwright specs: on-screen captions, ElevenLabs voiceover synced to timestamps, freeze-frame merge and background music. Auto-discover mode scans a project and writes the demo spec. Requires: ffmpeg, Node.js 18+, Playwright in the target project, an ElevenLabs API key for voiceover |
| podcast-slides-video | 2026-10-25 | Build a YouTube-ready MP4 from narrated audio (a NotebookLM overview, a recorded talk) plus a slide deck (PDF or PPTX), with slide changes cut to the transcript. Produces the MP4, an auditable cue sheet, a validation contact sheet and a YouTube chapter list. Requires: ffmpeg/ffprobe, uv (MLX Whisper on Apple Silicon, validator dependencies), poppler, LibreOffice for PPTX input |
Available Plugins
| Plugin | Last Modified | Description |

| hlx-admin-api-executor-guarded | 2026-10-25 | The hlx-admin-api-executor skill plus a PreToolUse hook that asks before any curl write to admin.hlx.page or api.aem.live. Claude Code only |
| ai-builder-kit | 2026-09-13 | Every skill above as one plugin, for Claude Code (ai-builder-kit@ai-builder-kit) and Codex (.agents/plugins/marketplace.json). Skills only, no hooks |
Getting Started
Pick one path. They all read the same skills/ folder.
Option A: npx skills (any agent, one skill at a time)
npx skills add jackzhaojin/ai-builder-kit --list # see what is available
npx skills add jackzhaojin/ai-builder-kit --skill excalidraw # into this project
npx skills add jackzhaojin/ai-builder-kit --skill excalidraw -g -a claude-code codex # global, Claude Code + Codex
npx skills add jackzhaojin/ai-builder-kit -g -y # everything, global
npx skills update -g -y # pull updates later
