Practical Notes
- Quant: track how many repos adopt the pointer-style
AGENTS.MDline; the goal is 1 shared source of truth, not copy/paste drift. - Quant: run the validator on every commit and measure “skills failing lint” rate over time (it should trend down).
Why pointer-style AGENTS beats copy/paste
Copying guardrails into every repo guarantees divergence. Pointer-style rules give you:
- One canonical shared rule set.
- Fast updates across the fleet.
- Clear “local overrides” when a repo truly needs them.
How to introduce safely
- Start with one pilot repo.
- Add the pointer line at the top of
AGENTS.MD. - Keep repo-specific notes below it.
Maintenance habit
When a guardrail changes, update it once here, then roll it out like any dependency update: changelog + verification run.
FAQ
Q: Is this only useful for one author’s repos? A: The pattern generalizes well: shared scripts + shared rules are valuable in any multi-repo team.
Q: Do I need Bun? A: Only for rebuilding certain compiled helpers; the guardrail text and hooks can still be used without it.
Q: What is the biggest failure mode? A: Breaking changes to shared rules without a rollout plan—treat updates like dependency upgrades.
