Run your agent normally. Then check what it learned:
gcsee your agent's brain
curl localhost:9000/statusone-line summary
curl localhost:9000/logrecent activity
curl -X POST localhost:9000/feedback -d '{"rating":"down"}'thumbs-down a bad response. your agent won't make that mistake again.
What happens after you install
It gets smarter every day.
Day 1
Your agent learns 12 facts from your first few tasks. Type gc to see them.
Day 3
It caught a mistake you made last week before you made it again. You didn't ask it to.
Day 5
Competence bars show python 87%, css 43%. Your agent knows what it's good at.
Day 7
Background reviews run when idle. Daily audits show what the agent learned.
Day 10
If your agent keeps struggling in one area, GreenCube spins up a focused sub-agent for that domain and routes matching tasks to it automatically.
Under the hood
5 systems. One runtime.
Runs locally. 145 tests. SQLite database you own.
Memory
Extracts facts from every task. Injects relevant ones into future requests. Decays unused entries over time.
Self-verification
Scores every response 1-5 against the original request. Low scores drop competence and trigger retries.
Competence tracking
Per-domain confidence from real outcomes. Knows python 87%, css 43%. Routes tasks based on actual success rates.
Mistake prevention
Stores corrections from thumbs-down feedback. Catches matching patterns in future tasks before they fail.
Auto-routing
When the agent keeps struggling in a domain, spins up a focused sub-agent for that domain. No user action required.
