Software engineering used to have one true code quality metric: WTFs per minute.
But in the age of agentic development, nobody reads code anymore — we supervise entities
that write it. The metric had to evolve.
same energy, new target
# The bands
"How many times did I yell at my agents before the task was done?"
live reading from an average tuesday
0–2
😌
Great agentic workflow
Either the agent behaved, or you have given up entirely.
3–5
😐
Needs better prompting
You said "actually" more than once. It was noted.
6+
🔥
I'm doing the task myself
The oldest fallback architecture known to engineering.
# How it works
A Claude Code hook watches every prompt you submit and scores it — fully locally.
No model calls, no network, no telemetry. Just a pile of honest heuristics
and a JSONL file that knows too much about you.
no cloud was harmed in the measuring of this rage
despair+4
"forget it, I'll do it myself"
profanity+3
the classics — in English and German
correction+2
"I said…", "that's not what I asked"
terse-rejection+2
"wrong again"
repetition+2
same prompt, second time, slower
caps+2
WHY ARE YOU STILL EDITING THAT FILE
negation-start+1
"no", "stop", "why", "ugh"
punctuation+1
!! ??? ?!
rapid-fire+1
short prompt, <25s after the last one
Deliberately not counted: code blocks and stack traces (pasting FATAL!!! is not anger),
short acronyms like API or TODO (not shouting), and /rage itself
(checking your rage is not a rage event).
# The report
Type /rage whenever you want the damage report.

# Install
Two commands inside Claude Code:
# add the marketplace
/plugin marketplace add rangulvers/rage-o-meter
# install the plugin
/plugin install rage-o-meter@rage-o-meter
Then just work as usual. The meter runs itself.
Privacy: everything stays in ~/.claude/rage/ on your machine.
Only an 80-character excerpt of flagged prompts is stored. Calm prompts never touch disk.
Wipe it any time with --reset --yes.
# The gallery
Everyone thinks their agent is the worst. Prove it.
Run /rage --share, open a pull request with the card it prints,
and your stats go up on the wall.
# generate your gallery card
/rage --share
Cards carry counts, verdict, and signal names only — never anything you typed.
