Kleio vs Git Blame / Log
Git shows what changed.
Not why it ended up that way.
Commits are more verbose than ever. But verbosity doesn't equal reasoning. Kleio captures the intent that git can't.
Where Git Blame works well
- Free, universal, and already part of every developer's workflow.
- Shows who changed what and when — line-level attribution.
- Commit messages can carry intent when teams have strong discipline.
- Diffs are the definitive record of what actually changed in the code.
- Integrations everywhere — every tool reads git history.
Where it breaks down
- Commit messages contain the why — until decisions happen outside of git. Reasoning lives in PRs, Slack, and meetings.
- Squash merges destroy individual commit history. The carefully written commit messages vanish into a single squash.
- AI-generated commits are verbose but meaningless — they describe what changed, not why it should have changed.
- Rebases rewrite authorship and ordering. Git blame tells you who to blame, not why they did it.
- Cross-file reasoning is invisible. A decision that spans 5 files shows up as 5 disconnected commits.
- No semantic search. Finding "all decisions about auth" means grep-ing through thousands of commit messages.
- No one reads them anymore. Even with AI making commits more verbose, the signal-to-noise ratio has dropped.
How Kleio is different
- Checkpoints intentionally differ from commits — they record validation, deferrals, and meaning that survives squash/rebase.
- Signal links connect commits to the decisions and context behind them — the why behind the what.
- kleio_ask provides semantic search over decision history — not just keyword matching in commit messages.
- Captures decisions from all sources, not just the ones that make it into a commit message.
- Cross-cutting decisions that span files, PRs, and sessions are first-class objects, not disconnected commits.
- Works alongside git — doesn't replace it, adds the decision layer that git history can't provide.

Better together or full replacement?
Complementary. Git is the definitive record of what changed. Kleio adds the why layer — the decisions, tradeoffs, and context that produced those changes. You'll still use git blame for line-level attribution. You'll use Kleio to understand why the code ended up that way.
