At least for gondolin and microsandbox, you bind a specific secret placeholder to the target host. i.e. your GH token is only replaced/injected for calls to api.github.com, not other hosts. And you can set up both with deny-by-default
Only if the replacement is global and not, say, only looking and inserting it into the actual (eg) Authorization header. If something is only transparently altering the Authorization header, then an agent inserting the dummy value somewhere else is totally safe.
For clarity, there is no "search and replace" function going on. It's only setting the header.
The main reason a "proxy-managed" env var is set is because most CLI tools assume if the env var is set, auth is set. If the env var is unset, it will assume auth needs to occur. Fortunately, most don't do a pattern matching on what the value actually is.
Oh, 3x at work. I shared some details on the methodology, its PR rate for ticketed features / bugs (so e.g. closed tickets as opposed to commits, loc, etc). For prompts and tasks, am happy to share (redacted as needed; check comment threads) if you want more details, presuming this is a genuine request? Here's a few example prompts (I can't paste exactly obviously, but I can approximate):
- "Rails / sidekiq: <x file> uses sidekiq batches. <y file> does it. Refactor your to use pattern in <x file> Match spec in <z file> then run rspec and rubocop"
- "Typescript / react. <x file>. Why is typescript compilation a bottle neck int his file. Use debugger to provide definitive evidence. Cast type to any and run script and time it; write a script to measure timing if needed. Iteratively work from type `any` to a real type and measure timing at each step. Summarize results"
- "I redefine <FormComponent> in five places. Find them all. Identify the shared patterns. Make new component in <x location>. Refactor each to to use new component. Run yarn lint and fix any ts issues when done"
- "<file y>: more idiomatic" (it knows my preferences)
Side projects and such I have no idea, and (as you noted) I do those quite infrequently anyways! Actually come to think of it... outside of the toy iOS work I did last week, I've not actually worked on my side projects since getting into Claude code / cursor agents. For work stuff, I guess other metrics I'd be interested in are total messages sent per task. I do sometimes look at $ per task (but for me anyways, that's so wildly in my favor I don't think it's worth it".
