A message lands in the group chat: "Can you take a look at this repo? Something's off with it."
Before I clone it, before I read the README, before I open the code, I run one command. It takes ten seconds, and it changes how I read everything that follows.
npx @wuchunjie/gitpulse .
It's a zero-dependency git analytics tool — it reads the .git directory on your machine and prints the repo's shape: commit totals, contributor distribution, active days, file breakdown, recent activity. Nothing leaves the machine.
Here's what the output looks like on a real project:
Total commits: 1
Contributors: 1
Active days: 1
Files touched: 4

What the ten seconds tell me
1. Who actually maintains this. The contributor graph answers "how many people does this depend on?" One name with 95% of the commits means the person who sent me the message is the whole maintenance story. Two names split 60/40 means something else. The "something's off" in the message gets a very different reading depending on which.
2. When it was last alive. Active days and recent activity tell me the repo's current tense. A repo with 200 commits but zero activity in 8 months is a museum, not a project — "something's off" might mean "it stopped working and nobody's coming to fix it." A repo with 30 commits and activity last week is a live organism, and "something's off" is a current wound I can expect to get a response on.
3. What the repo is made of. The file type breakdown is a fast map of the codebase's center of gravity. A repo that's 60% .md is a documentation project with a thin code core. One that's 80% .ts with a .sql cluster has migrations that matter. I open the right files first because the shape told me where the mass is.
4. How much history I'm inheriting. Total commits sets my expectation for the archaeology. Twenty commits: the whole history fits in one git log read. Four thousand: I'm going to need gitpulse's breakdown and a search strategy before I touch anything.
Why this beats "just open the code"
Because triage changes what I'm looking for when I open the code. Walk into a repo blind and you read files in the order they appear. Walk in after the ten seconds and you read in the order of risk:
- Contributor graph says one person owns 90% → I look for the files that person wrote last, because that's where the current thinking lives.
- File breakdown says 40% of the mass is test files → I read the tests before the source; the tests tell me what the author believed the system did.
- Recent activity says a burst of commits three days ago → I diff that burst first; "something's off" is probably in the most recent change.
The tool doesn't answer "what's wrong." It answers "where should I look first, and what should I expect to find." That's the difference between ten minutes of wandering and ten minutes of aimed reading.
The version I run on my own repos
Same command, different question. Before I start work on my own repo after a break, gitpulse is the orientation pass: what changed while I was away, who touched what, whether the activity pattern shifted. It's the difference between picking up a project from memory and picking it up from evidence.
The honest limit
gitpulse is a census, not a diagnosis. It tells you the shape of the repo — contributors, activity, file mass. It doesn't tell you the code is good, the tests pass, or the architecture is sane. Those are still your job, with your eyes, in the files.
But the ten seconds it costs to get the census before you start reading is the cheapest orientation pass I know. And for the "take a look at this repo" message, it's the difference between replying "what do you mean, something's off?" and replying "the last burst of commits is in the auth module — I'm looking there."
