My Personal catalog of Agent Skills — portable instruction sets for AI coding agents. One install command works across Claude Code, OpenCode, Codex, Antigravity, Cursor, and every other agent supporting the Agent Skills specification.
- Run the skills.sh installer:
npx skills@latest add su-ekachai/skills- Pick the skills you want, and which coding agents to install them on.
| Category | Skill | Description | Version |
|---|---|---|---|
| writing | technical-writing |
12 technical writing rules with Write and Review modes for documentation, comments, commits, pull requests (PRs), and Obsidian notes | 1.0.0 |
| writing | blog-writing |
Personal blog voice with Draft, Humanize, and Review modes: a voice fingerprint from live posts plus a curated blog AI-pattern list | 1.0.0 |
| finance | fundamental-analysis |
Equity research notes for Obsidian: 10-section beginner-readable analysis, multi-model fair value, scored verdict; Analyze and Refresh modes | 1.0.0 |
| finance | crypto-news-screener |
Impact-scored crypto news screening: deduplicated stories from tiered sources with price direction and a 1–10 rubric; window and watchlist overridable | 1.0.0 |
The catalog contains only authored skills. technical-writing and
blog-writing curate their AI-pattern references from
avoid-ai-writing and run
it as a final pass when it is installed
(npx skills add conorbronsdon/avoid-ai-writing).
Every skill in use, by source. Authored skills live in this repository; third-party skills install from their upstream repositories per their own documentation.
User-invoked skills run only when typed as a slash command; their job is to orchestrate. Model-invoked skills are reached automatically by the agent when a task fits their description.
