Every team using AI coding agents starts the same way: someone drops a CLAUDE.md (or .cursorrules, or a copilot-instructions.md) into a repo. It works. So the next repo gets one too. And the next.
Then you look up and you have 20 repos, 6 teammates, and 3 different AI tools — and no two of those config files are the same. Which one is right? Nobody knows.
I hit this wall running an integration platform with dozens of small repos. This post is the pattern I landed on, and a small open template you can clone to do the same.
Why a single instructions file breaks
A single file is perfect for one repo and one person. At team scale it fails in five predictable ways:
- It doesn't scale. Every repo gets a slightly different copy. There's no "the standard" — there are 20 forks of it.
- It drifts. Someone improves the file in one repo. That improvement never reaches the other 19.
- It's unversioned. No history, no ownership, no review. Your "AI brain" is the one artifact in your stack nobody code-reviews.
- It's tool-locked. Cursor's format isn't Claude's isn't Copilot's. Switch tools and you start over.
- It rots. The code changes; the instructions don't. Six months later the agent is confidently working from a map of a city that's been rebuilt.
None of these are exotic. They're just what happens when a copy-pasted file meets a growing team.
What already exists (and what it doesn't fix)
-
Curated rule lists (e.g.
awesome-cursorrules) are great for inspiration, but they're copy-paste, single-tool, and have no sync or freshness. - Skill/agent sync tools distribute tools across agents. Useful — but they solve distribution, not your team's standards, versioning-as-review, or the rot problem.
-
The Agent Skills standard +
AGENTS.mdare the right substrate to build on, not competitors.
The gap: nobody treats the standards themselves as code — owned, versioned, reviewed, and automatically distributed.
The pattern: standards-as-code
Three moves:
-
Put your standards in one git repo. Two kinds of artifact:
- Rules — standing behavior ("always validate input", "never log PII").
-
Skills — task workflows ("here's how to cut a release"), in the portable
SKILL.mdformat.
-
Auto-sync them into your editor. A setup script links
skills/andrules/into your tool's config directory. Git hooks re-run the sync on everypull/checkout/rebase. - Change them through pull requests. Improving a standard is now a reviewed diff, not a silent edit in one repo.
Git repo (source of truth) ~/.cursor/
skills/ ──────────────└ skills/ (junction/symlink)
rules/ ──────────────┤ setup + rules/ (synced .mdc)
└── git hooks ─────────→ every workspace, every teammate
Because rules sync to the user level, they apply in every workspace automatically. Update the repo, everyone git pulls, and the whole team's standards move together — no per-repo copies.
Why this beats a bare CLAUDE.md
| standards-as-code | bare CLAUDE.md
|
|
|---|---|---|
| Scales across repos | Yes (one source) | No (N copies) |
| Versioned + PR-reviewed | Yes | No |
| Auto-distributed | Yes (sync + hooks) | Manual |
| Freshness mechanism | Yes (later in the series) | No |
It's the difference between a shared library and a code snippet everyone pastes.
Try it (v0.1)
I packaged the mechanism as an open template: agent-standards-kit (this post pins v0.1).
git clone https://github.com/prathakmalik/agent-standards-kit.git
cd agent-standards-kit
./scripts/setup.ps1 # Windows/Cursor; no admin needed
Restart Cursor and your sample skills + rules are live. Swap in your own — the repo ships templates and a de-identified worked example.
My honest take
This is not another skills manager — that niche is crowded. It's a methodology plus a starter template, proven on a real multi-repo platform. Its value is the boring, durable stuff: team+repo scoping via plain git, review of changes, and (coming in this series) a loop that keeps the standards from rotting. If you're one dev on one repo, a single file is genuinely fine. The moment there's a team, treat your AI standards like code.
Coming up next (v0.2): One source of truth is great — but your team doesn't all use the same AI tool. Next post: making the same skills and rules work across Cursor, Claude Code, and GitHub Copilot, with cross-platform setup (bash and PowerShell). Star the repo to follow along.
If you found this useful, a ⭐ on the repo helps more than you'd think.
