How to Trust Your Coding Agents More

How to Trust Your Coding Agents More

AI X
To trust your coding agents, stop over-prompting and start engineering your codebase to be inherently agent-friendly.
What: Developer Lauren Tan advises using static analysis, strict types, and automated verification like TLA+ rather than relying on human review for every PR generated by agents.
Why it matters: This advocates for an 'inverse pyramid' approach where most effort is spent on robust system architecture that prevents agent failure by design, rather than manual oversight.
Takeaway: Install the Cursor plugins and use '/correct' and '/architect' on past commits to identify and rearchitect the parts of your codebase where agents struggle most.

  • TLA+: A high-level formal specification language used for designing, modeling, and verifying concurrent and distributed systems.
  • Invariants: Logical assertions that must always remain true in a program's state to prevent bugs.

  1. codebase improvements: this is just good software engineering - better architecture, stronger types and invariants, clear boundaries. agents love to copy what exists and take the shortest path, so make the easy thing the right thing. categorically eliminate problems through code and you won't need to think about it again.
  2. static analysis: lint rules, tests, CI, verification (eg TLA+). very token efficient ways to catch issues ahead of time.
  3. prose: comments, rules, AGENTS.md, skills - anything that can't be enforced and requires agent judgment. use it minimally, but do use /create-verification-skill.
  4. human review: the hardest to scale. at the rate agents land code, it's pretty much impossible to thoroughly review every PR, so spend that effort on the highest leverage point, designing an environment where agents do the right thing by default.

this forms an inverse pyramid: you want most of your effort at the top, least at the bottom. codebase improvements are deterministic, making it more token efficient, and lets you sleep more soundly at night.

install github.com/cursor/plugins and create a new Project:

  1. look through my slack/chat messages and code review comments where i've given feedback on PRs, code, architecture
  2. use /recall on my past transcripts to learn how i steer agents
  3. /poteto-mode use /correct and /architect on past commits to find the most common pitfalls agents fall into, then propose a plan to rearchitect the code i own so it's more agent friendly. answer open questions with prototyping rather than defer to me, and back the plan with real data.
  4. before you begin, use /sharpen + /in-your-own-words and confirm this prompt with me
