Show HN: Grepathy – Claude made a decision nobody approved

https://github.com/evansjp/grepathy
13•evansjp•1h ago
hey HN - Claude pre-created users in Clerk with null emails/names as "guest users" on a contract job. Wasn't in any plan. The CTO asked why, and I didn't know! I didn't make that decision!

The reasoning was in a transcript on my laptop. Claude Code deletes those after 30 days by default. Two of my projects lost their whole history that way.

Grepathy distills transcripts locally into markdown committed with the code. Decisions only, never your messages, no server.

List every decision nobody approved:

  grep -rn "agent-initiated" .ai/why/
Ran a blind eval before shipping, published it including the misses (REPORT.md). Agents with Grepathy answered the "why" questions right. Baseline agents made up confident wrong answers.

Good catch on CTOs part. That scenario is one that keeps me awake at night -- that some large PR of mine has come functionality or feature that I didn't ask for and didn't notice.

How did the CTO respond to "Claude did it and I didn't catch it"? Did the AI PR summary mention it? Or did the CTO just read the code?

evansjp•52m ago
CTO responded well to it - frankly because we're all using some coding agent and it's just the natural process of code review for them to sniff things out. No mention of it in any PR summary - CTO found it in the migration that would mutate the User record to accept `null` email.

I am fighting against people doing this every day, and we've made it extremely clear that your computer and processes running on it are an extension of you, a human, who is responsible for the actions on your computer.
Synthetic7346•27m ago
Won't that slow you down a lot? I get it in principle, but in practice if you have to review everything your coding agent does the productivity gains diminish significantly
extrabajs•16m ago
I guess you get to choose between reviewing it yourself or wasting someone else’s time
sixtyj•1h ago
Well done.

This is not just Claude’s behaviour :)

It could be used for every agentic coding as well, because I have experienced such mess so many times in last three years.

One issue repaired, another one touched and changed…

evansjp•47m ago
thank you so much! started with a Claude Code adapter, but you think Codex would be a good next one?

Thanks for today's dose of impostor syndrome cure.

> Decisions only, never your messages

For me this is basically the opposite of how it would need to be, the decisions are all in my messages to the agent, almost never directly in the agent's replies, sometimes indirectly though I suppose.

Interesting to see that apparently some people use these tools and are the ones listening and doing what the LLM decide and says, rather than the opposite.

> Ran a blind eval before shipping, published it including the misses (REPORT.md). Agents with Grepathy answered the "why" questions right. Baseline agents made up confident wrong answers.

Is this eval public anywhere? The whole ecosystem severely lacks transparency, and people continue making strong claims without any sort of data or results that backs these up. Is there any public somewhere backing up the idea that it's more accurate that just using whatever agent harness?

> Claude made a decision nobody approved

It irks me a tiny bit that this is essentially clickbait, you don't know for sure Claude "made a decision nobody approved" as you've lost the data because you never thought sufficiently about storing these things in the first place. Most likely it misunderstood you at one point, you didn't carefully read the reply and approved it all, so most surely what you've done lead to that being done. These big models hardly ever just randomly do whatever, you can more often than not trace it to something you did wrong.

SpicyLemonZest•45m ago
Can we get the transcript of the session where you had Claude write this post? I want to understand the "why" behind this project, and whether a human being was at any point involved in the "blind, pre-registered evaluation of Grepathy against an honest baseline".

Wait what? Claude Code (and Codex) transcripts are auto-deleted??

That's a treasure trove of information for all my projects and I had built some tooling and workflows tahat deal with extracting insights from them -- withut ever realizing I mightbe losing old chats. Thanks for this -- I may need to include an archival step for retention.

weird-eye-issue•33m ago
Yes but it's just a setting you can change I don't think you really need an archival step

Throw that in ~/.claude/settings.json

simonw•2m ago
Horrifying, isn't it?

Amazing to me how little these companies respect the historic value of the transcripts. Most of my work is captured in them now.

vanyaland•36m ago
Your .ai/why/main.md is at 97KB and 148 entries. Does anything prune that, or does a long-lived branch keep growing?
trjordan•20m ago
100% important. But what decisions do you care about seeing?

The whole point of the agent is to make decisions for you. If you want to make every little detailed decision, just write the code.

The whole art of this problem is figuring out which decisions matter to you, and how to surface them.

(Disclosure: we're working on this too. https://tern.sh)
