01coder Agent Skills

June 3, 2026 · View on GitHub

A marketplace of agent skills by VerySmallWoods — content creation, publishing, analytics, and security scanning. Works with Claude Code, Codex, Cursor, Windsurf, and any other coding agent that supports the skills.sh format.

Install

Universal (Claude Code · Codex · Cursor · Windsurf · ...)

Uses the skills.sh installer by Matt Pocock:

npx skills@latest add sugarforever/01coder-agent-skills

Pick the skills you want and the agents to install them on. Done.

Claude Code (native marketplace)

/plugin marketplace add sugarforever/01coder-agent-skills
/plugin install 01coder-skills@01coder-agent-skills

New skills are picked up automatically on marketplace update — no reinstall needed.

Available Skills

Content & Writing

  • personal-chinese-writing-style — Personal writing-style preferences (punctuation, structure, voice). Reference when writing, translating, or editing content.
  • video-planner — Plan videos and prepare publishing materials: read-aloud scripts (口播稿) with per-section screen-share cues, plus title, description, tags, and YouTube chapter timestamps for YouTube and Bilibili.
  • cover-image — Hand-drawn style article cover image generator with 17 style options and 10 composition layouts.
  • tweet-insight — Read a tweet plus its linked papers / blogs / system cards, then write an original Chinese share-post in your own words.
  • share-reading — Draft social-media posts to recommend an article, paper, or resource across X, Substack, and 知识星球.
  • promote-post — Write a teaser tweet for a published article that opens the story instead of summarizing it — the tweet IS the first bite, not a label on the packaging.
  • slides-video — Orchestrate slide generation + script writing to produce slides-driven narration videos (口播视频), with each slide mapping 1:1 to one voiceover section.
  • subtitle-correction — Correct speech-recognition errors in .srt subtitle files (Chinese and English) while preserving timestamps.

Publishing

  • publish-x-article — Publish Markdown articles to the X (Twitter) Articles editor with proper formatting. Inspired by wshuyi/x-article-publisher-skill.
  • publish-substack-article — Publish Markdown articles to Substack as drafts, with Markdown-to-HTML conversion.
  • publish-zsxq-article — Publish Markdown articles to Zsxq (知识星球) as drafts.

Domain-Specific

  • fpl-copilot — Fantasy Premier League copilot. Syncs live FPL data into local SQLite, analyzes players/teams/fixtures, generates self-contained HTML reports for gameweek strategy, captain picks, fixture matrices, and transfer comparisons.

Security Scanning

  • nextjs-security-scan — Security vulnerability scanner for Next.js and TypeScript/JavaScript projects. OWASP Top 10, XSS, injection, secret scanning, dependency CVEs.
  • python-security-scan — Security vulnerability scanner for Python projects. Framework-aware checks for Flask, Django, and FastAPI.

Utilities

  • codex-cli — Delegate one-off tasks to OpenAI Codex CLI, including coding reviews, implementation passes, and image generation with proactive image path discovery.
  • diagram-to-image — Convert Mermaid diagrams and Markdown tables to PNG / SVG images for platforms that don't support rich formatting.
  • interactive-input — Embed interactive UI components (multiple choice, forms, surveys) in chat responses on compatible clients.

codex-cli Development Direction

The codex-cli skill is intended to let other agents, such as Claude Code or OpenClaw, deliberately consult OpenAI Codex CLI for scoped one-off work. It should behave like a bridge workflow, not a replacement for the host agent: first verify that codex is installed, delegate a clearly framed task through codex exec, then inspect and report the concrete result.

When improving this skill, keep it focused on practical Codex CLI operation:

  • Prefer non-interactive codex exec workflows over interactive sessions.
  • Shape delegated prompts with Codex best-practices sections: Goal, Context, Constraints, and Done when.
  • Use read-only for planning, review, critique, and image generation unless the user explicitly wants Codex to edit files.
  • For implementation tasks, encourage plan-first delegation before write-mode execution.
  • For image generation, always locate the generated file under $CODEX_HOME/generated_images/<session-id>/ or ~/.codex/generated_images/<session-id>/, verify dimensions when an aspect ratio was requested, and report the path proactively.
  • Do not claim a specific image backend model unless Codex output, logs, or metadata prove it.
  • Do not trust Codex's final message alone when file changes matter; inspect Git status, diffs, or output files.

Future additions should be small and evidence-oriented: better session-id extraction, safer output parsing, known CLI flag changes, and stronger image/file discovery are aligned with the skill. Broad Codex product documentation, general prompt engineering, or host-agent-specific behavior should stay out unless it directly improves this delegation workflow.

Integrations

  • add-feishu — Add Feishu (飞书 / Lark) as an agent channel via WebSocket long connection. No public URL required.

Creating a New Skill

  1. Create skills/<skill-name>/SKILL.md with YAML frontmatter: 
    ---
name: skill-name
description: When to trigger this skill. Be specific about trigger phrases — include Chinese and English if applicable.
---
  2. Run ./scripts/sync-marketplace-skills.sh to regenerate the skills[] array in .claude-plugin/marketplace.json, then bump the version manually.
  3. (Optional) Add references/, scripts/, assets/, or templates/ directories alongside SKILL.md for domain knowledge, automation, or report templates.

See CLAUDE.md for the full convention.
