Nine agent skills trending this week, plus a SKILL.md starter

A skill is a text file

Your coding agent reads a SKILL.md when its trigger matches. The header (the bit between the --- lines) says when it applies. The body says how to behave. No code runs. Claude Code, Codex, Cursor and OpenCode all read the same file, from a folder like ~/.claude/skills/<name>/SKILL.md, ~/.codex/skills/<name>/SKILL.md or .cursor/skills/<name>/SKILL.md.

Nine of the 22 repos on GitHub's weekly trending page (read 15 Sep 2026, 22:40 IST) are skills or skill frameworks. 53,148 stars between them in seven days. Star counts below are from the GitHub API the same night; install lines are copied from each README.

The nine

1. i-have-adhd (ayghri) · +17,658 this week, 46,085 total, #1 on the page

Stops the agent burying the answer. Action first, steps numbered, one next action at the end, no tangents. Ten rules in one 7KB file; the other 63 files in the repo are mostly installers.

Install: paste this into your CLI:

Install the i-have-adhd skill/plugin from https://github.com/ayghri/i-have-adhd, refer to the repo's AGENTS.md for instructions.

3. ponytail (DietrichGebert) · +7,722, 139,184 total, three months old

The lazy senior dev. Does this need to exist, stdlib, platform, one line, only then code. Their own benchmark (12 tasks, n=4, Haiku 4.5, same repo with and without the file) reports about 54% less code on average.

A SKILL.md starter

Write the one rule your agent keeps breaking. This is the rule I would write first. Save it as ~/.claude/skills/answer-first/SKILL.md (or the matching folder for your CLI) and invoke it with /answer-first.

---
name: answer-first
description: When I ask for a fix, a command or a path, lead with it. Invoke with /answer-first; stays on until "normal mode".
---

# answer-first

The first line is something I can run or open. Prose after, if at all.

1. Command, path or snippet first.
2. Number multi-step work. One bounded action per step.
3. End with one next action I can do in under two minutes.
4. A second issue is a separate question, offered after the first is done.

These rules stay on for the whole session. Turn off on "normal mode" and confirm in one line.

Two of the nine run on my machine (superpowers and ponytail). i-have-adhd I read the night I wrote this. Which rule would you write first? Reply to the DM, I read every one.
