Available Skills

Red Pen

A strict editorial reviewer that checks writing, inspired by Orwell’s “Politics and the English Language” rules and Butterick’s Practical Typography.

Accessibility Review

Audits components, pages, and screenshots against WCAG 2.1/2.2 Level AA. Returns prioritized findings (Critical/Warning) with specific fixes rather than generic guidance.

WordPress Add Links

Scans a blog post draft, finds relevant internal and external link opportunities, and weaves them into existing sentences without disrupting the flow.

Create PRD

Plans features interactively. Asks clarifying questions, then generates a detailed PRD document with user stories, acceptance criteria, and technical considerations.

Ralph: Create JSON Issues

Converts a PRD or plan file into right-sized JSON stories for the JSON loop. Reads from .claude/plans/, plans/, or prds/, sizes each story to one context window, and wires up cross-PRD dependencies.

Fresh Eyes

Re-reads code you just wrote as if seeing it for the first time. Catches off-by-one errors, missed edge cases, naming issues, and logic bugs, then fixes them on the spot.

Humanize

Rewrites AI-generated text so it reads like a person wrote it. Applies 30 rules across 6 categories based on Wikipedia’s AI writing patterns guide, preserving meaning while removing robotic phrasing.

Markdown Image Alt Text

Reads each image in a markdown file, describes its content, and writes detailed alt text inline. Works with both Obsidian wiki-style (![[image]]) and standard markdown formats.

Motion Design

Evaluates UI animation needs and recommends specific easing curves, durations, and implementation approaches. Every animation gets a job, or it gets cut.

Ralph: GitHub Create Issues

Converts a PRD or plan file into GitHub Issues (parent + sub-issues). Reads from .claude/plans/, plans/, or prds/, sizes stories for single-context execution, and links dependencies via GitHub’s native blocking. This is the workflow I use.

Ralph: GitHub Start Loop

Autonomous development loop powered by GitHub Issues. Fetches open PRD issues, spins up git worktrees, implements stories, closes sub-issues on commit, and opens a PR when done.

Ralph: JSON Create Issues

Converts a PRD or plan file into right-sized JSON stories for the JSON loop. Reads from .claude/plans/, plans/, or prds/, sizes each story to one context window, and wires up cross-PRD dependencies. Learn more at richtabor.com/ralph.

Ralph: JSON Start Loop

Autonomous development loop powered by local JSON files. Picks up stories from .claude/plans/, plans/, or prds/, spins up git worktrees, and executes them one by one without manual intervention. Learn more at richtabor.com/ralph.

Review PR

Reviews PR comments from GitHub (Copilot, reviewers), evaluates them against actual code, replies with reasoning, and resolves threads.

Review AGENTS.md

Detects missing AGENTS.md files, creates them using progressive disclosure principles, and symlinks CLAUDE.md. Proactively checks new projects and handles all combinations of existing files.

Skill Review

Validates agent skills against the Agent Skills standard. Audits structure, frontmatter, description quality, progressive disclosure, and anti-patterns, then returns a scored report with actionable fixes.

Technical Writing

Turns the feature you just built into a technical blog post. Analyzes your codebase for implementation details, structures the narrative, and avoids AI-sounding language. Supports WordPress publishing.

X Writing

Turns notes and ideas into X posts that sound like you wrote them. Pulls ideas from a markdown file (X_SOURCE_FILE) or macOS Notes (X_NOTES_APP_SOURCE), identifies the most shareable angle, and drafts posts matched to your voice. Saves approved posts to X_DRAFTS_FILE.

Structure

Each skill lives in its own folder:

skill-name/
├── SKILL.md              # Required: Instructions and metadata
├── references/           # Optional: Documentation loaded as needed
├── scripts/              # Optional: Executable code
└── assets/               # Optional: Templates, images, etc.
