# builder-skills [![skills.sh](https://skills.sh/b/waynesutton/builder-skills)](https://skills.sh/waynesutton/builder-skills) [![npm](https://img.shields.io/npm/v/@waynesutton/builder-skills)](https://www.npmjs.com/package/@waynesutton/builder-skills) [![license](https://img.shields.io/badge/license-Apache--2.0-blue)](LICENSE) Agent skills for builders shipping Convex apps. By [Wayne Sutton](https://waynesutton.ai). Seventeen skills. Fourteen teach an agent how to build on [Convex](https://convex.dev) the way the docs say to: validators on every function, indexes over filters, idempotent mutations, HTTP actions that verify signatures, migrations that do not take the app down. Three teach it how to run a project: write a PRD before touching code, keep `task.md`, `changelog.md`, and `files.md` true from git evidence, and never run a git command that can destroy work. They work with Claude Code, Codex, Cursor, OpenCode, and anything else that reads a `SKILL.md`. Looking for the official Convex skills? Those are at [get-convex/convex-agent-plugins](https://github.com/get-convex/convex-agent-plugins). This repo is my opinionated set, tuned for how I build. ## Install Three ways in. Pick one. <details open> <summary>skills.sh (any agent, editable files)</summary> ```bash npx skills add waynesutton/builder-skills ``` The installer asks which skills you want and which agents to install them for. It writes ordinary files into your repo that you can edit. Pull my updates later with `npx skills update`. </details> <details> <summary>Claude Code plugin (managed, auto updates)</summary> ```bash claude plugins marketplace add waynesutton/builder-skills claude plugins install builder-skills@waynesutton ``` Or inside a session: ``` /plugin marketplace add waynesutton/builder-skills /plugin install builder-skills@waynesutton ``` </details> <details> <summary>npm CLI (pick your target folder)</summary> ```bash npx @waynesutton/builder-skills install-all npx @waynesutton/builder-skills install-all --target codex npx @waynesutton/builder-skills install-all --target cursor npx @waynesutton/builder-skills install convex-functions project-workflow npx @waynesutton/builder-skills install-templates ``` `--target` takes `claude` (default, `.claude/skills`), `codex` (`.codex/skills`), `cursor` (`.cursor/skills`), `agents` or `opencode` (`.agents/skills`), or any path. Add `--link` to symlink instead of copy. </details> ## Then run `install-templates` ```bash npx @waynesutton/builder-skills install-templates ``` This drops five starter files at your project root and two editable skills in `.claude/skills/`: | File | What it is | | --- | --- | | `AGENTS.md` (+ `CLAUDE.md` symlink) | Stack, commands, rules, and a pointer to the skills | | `files.md` | One line per file. What it is for. | | `changelog.md` | Keep a Changelog. Dates from `git log`, never invented. | | `task.md` | To Do / In Progress / Completed with UTC timestamps | | `prds/lessons.md` | One line per lesson learned. Read at session start. | | `.claude/skills/dev/` | House style. Edit it. | | `.claude/skills/help/` | Root cause first, confidence bar, what not to touch. Edit it. | Nothing existing gets overwritten. ## Why these exist I build with Convex every day and I got tired of the same three failures. **The agent forgets the Convex rules.** It writes `filter` instead of `withIndex`. It skips the `returns` validator. It schedules `api.*` instead of `internal.*`. It puts `Date.now()` in a query and wonders why the cache never hits. The `convex-*` skills fix that. Each one is short, points at https://docs.convex.dev/llms.txt for the current API, and pushes deep material into `references/` so the agent only loads what the task needs. **The agent starts coding before it knows what it is building.** `project-workflow` makes it triage first, write a two screen PRD in `prds/`, track the work in `task.md`, and record a lesson when the same correction happens twice. **The docs drift from the code.** `project-docs` reads `git log` and the working tree, then updates `changelog.md`, `files.md`, and `task.md` from what shipped. It refuses to log a Convex component that is not registered in `convex.config.ts`, and it scans for secrets before saving. The evidence rules borrow from [get-convex/convex-hackathon-skill](https://github.com/get-convex/convex-hackathon-skill). And one more that cost me two days once: `git-safety`. No `reset --hard`, `checkout -- .`, `clean -fd`, or `stash drop` without the user saying yes to that exact command. "Undo" means edit the file, not check it out. ## How I build with these The loop is short. Ask for the change. The agent writes a PRD in `prds/`, builds against it, and moves the task through `task.md`. When it lands, `/project-docs` reads the git evidence and updates the three docs. Then I commit with the message it prints. A project run this way ends up with four things next to the code: ``` prds/ one PRD per non trivial change, plus lessons.md task.md what is queued, in flight, and done, with UTC timestamps changelog.md what shipped, dated from git log files.md what every file is for ``` [waynesutton-ai](https://github.com/waynesutton/waynesutton-ai) is the live example. This repo runs the same loop on itself. ## Skills ### Convex | Skill | Use when | | --- | --- | | [convex](skills/convex/SKILL.md) | Convex task with no closer match.

The description is third person and ends with a `Use when ...` sentence, because that is what the agent reads to decide whether to load the skill. Everything else is progressive disclosure: metadata always, body on match, references on demand. This follows the guidance in Anthropic's [Agent Skills overview](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/overview) and OpenAI's [Rethinking skills and prompts for GPT-6 Astra](https://developers.openai.com/blog/rethinking-skills-and-prompts-for-gpt-6-astra): short routers over long itineraries, triggers in the description, deep content one hop away. ## Programmatic use ```js import { listSkills, getSkill, getSkillMeta, SKILLS } from "@waynesutton/builder-skills"; listSkills(); // ["avoid-feature-creep", "convex", ...] getSkillMeta("convex-functions"); // { name, description } getSkill("git-safety"); // raw SKILL.md ``` ## Repo layout ``` skills/ the 17 skills templates/ starters installed by install-templates bin/cli.js builder-skills CLI index.js programmatic API scripts/ check-skills.mjs, run with npm run check .claude-plugin/ plugin.json and marketplace.json .codex/skills/ symlinks into skills/ so Codex finds them in this repo command/convex.md OpenCode slash command prds/ PRDs for this repo and lessons.md AGENTS.md agent context for this repo (CLAUDE.md symlinks here) GEMINI.md Gemini CLI context ``` ## Contributing Read [CONTRIBUTING.md](CONTRIBUTING.md). Short version: keep `SKILL.md` under 300 lines, frontmatter is `name` + `description`, every reference file is linked, `npm run check` passes. ## Related - [Convex docs](https://docs.convex.dev) and [llms.txt](https://docs.convex.dev/llms.txt) - [get-convex/convex-agent-plugins](https://github.com/get-convex/convex-agent-plugins), the official Convex skills - [get-convex/convex-hackathon-skill](https://github.com/get-convex/convex-hackathon-skill), evidence based build logs - [mattpocock/skills](https://github.com/mattpocock/skills), the repo whose shape this one borrows - [waynesutton/markdown-site](https://github.com/waynesutton/markdown-site), the Convex publishing framework behind waynesutton.ai - [skills.sh](https://skills.sh), the installer ## License Apache-2.0.
