The shell scripts is actually a fun bit: why use an AI for something that can be deterministic? We wrote a bunch of scripts that CI runs to enforce various things like the aforementioned docs. We also force any changes to agent skills / agents.md go into their own PR. 14.6K views · 44 likes · 0 reposts · 2 replies Open on X →

We also spent a bunch of time rewriting our agent skills to ensure we were giving our agents better instructions. We had a lot of cruft from 2025-era AI. 19.1K views · 33 likes · 0 reposts · 1 replies Open on X →

We wrote evals for our skills then tested them to see which had been consumed by modern LLM knowledge. We ultimately deleted a lot and then improved what remained. 17.6K views · 41 likes · 0 reposts · 2 replies Open on X →

While we were there, we found a lot of markdown docs had been accumulating from doc-happy agents and leading to context poisoning We're now centralizing our docs into a single docs folder and requiring those be written by humans. Location gets enforced by another shell script. 16.2K views · 56 likes · 1 reposts · 5 replies Open on X →

With a risk-based system, we agreed that if your change touched the public API/MCP, auth, design system, non-additive database schema changes, or agent skills, it needed a human review. We then enforced that with a shell script to add a github label. 25.7K views · 119 likes · 0 reposts · 5 replies Open on X →

Improving guardrails was pretty easy, just expensive in tokens and attention. We enabled nearly every rule in ruff/prettier/eslint/ty and we improved our unit test coverage to a floor of 85%. 23.3K views · 59 likes · 0 reposts · 3 replies Open on X →

We took a pretty high-level approach to o11y, preferring to instrument the customer-facing signals that indicate a bad time is about to happen (eg, ingestion, data processing, response times, auth). There's a few areas we went deeper on as needed, of course. 21.2K views · 38 likes · 0 reposts · 1 replies Open on X →

We decided to do a couple things instead: - Switch to a risk-based system - Improve our guardrails (unit and e2e testing, post-deploy o11y, stricter linting and type checking, etc) 29.8K views · 124 likes · 1 reposts · 4 replies Open on X →

I had been tossing around the idea for a while about having AI do all code review and so I just asked the team: what if we just...didn't review the PRs? 29K views · 39 likes · 0 reposts · 3 replies Open on X →
