Here's the thing I keep getting stuck on: agents are pretty good at writing local code now, but I still can't trust them with repo-wide changes. Once the change touches aliases, call sites, imports, generated-looking files, or a bunch of files at once, most of them still end up doing some version of search, patch, search again.

So I built my own set of structural refactoring tools for agents. Less "edit this blob of text," more "find the actual references, change the actual nodes, validate, snapshot, rollback if it explodes." The model doesn't get smarter — it just stops doing compiler work by hand.

In this demo, the agent uses the tools (getpando.ai if you want to look closer) to find exact references, apply a structural edit, validate the result, and snapshot before mutation. 290 files, 31 seconds.

I'm posting to look for similar large codebases, ugly cases: barrel exports, aliases, macros, generated code, weird imports, large repos, whatever. If you have a refactor where Claude or Codex typically faceplants, plz share it. I want to see if my tools can tackle it.

And if your honest reaction is "cool, still wouldn't use it" — I'd genuinely love to know why too.

Hi Clojurians,

pando is a tool for coding agents that treats code as data and has first class support for *structural* (i.e. using the AST) Clojure code navigation and editing. It works in addition to your existing tools - just connect over MCP.

I'd love your feedback on it - https://clojure.getpando.ai

Thank you kindly!

Here's what I did:

1. Built a proxy that intercepts Codex's calls to OpenAI and rewrites them on the fly.
2. Replayed 3,807 rounds of SWE-bench Verified traces through it: avg prompt 44k → 6k tokens (-87%).
3. Posted it here to get the next reduction applied to my confidence interval — starting with the inevitable "How about accuracy?"
