A commit message rarely contains the full decision behind the code.
Code history, connected
Understand why code exists — before you change it.
RepoLore traces code back through commits, pull requests, issues, and regression tests — then turns that history into an evidence-backed explanation.
Read-only. Evidence-linked. Built for public GitHub repositories.

Question
if (needsCompatibilityCheck(runtime)) {
applyLegacyFallback();
}
applyLegacyFallback();
}
Why does this compatibility check still exist?
Removal risk: High
Confirmed
Introduced in a bug-fix commit and preserved by a regression test.

Before changing it
Run the compatibility suite and verify the affected runtime versions.
The problem
Git blame tells you who. RepoLore helps explain why.
Pull requests, issues, patches, and tests hold different parts of the story.
A safe change starts with understanding the reason a guard or fallback exists.
How it works
From a line of code to a decision you can inspect.
Provide a public GitHub URL, file, and — when useful — a line range.
RepoLore investigates file history, commits, PRs, issues, patches, and tests.
Get a timeline, confidence level, evidence links, and validation plan.
What comes back
Useful output, with uncertainty left visible.
See how the implementation and its rationale evolved.
Find the change most likely to have introduced the behavior.
Connect code to the discussion and reported problem around it.
Identify tests that help preserve the current behavior.
Understand what a change may affect before proceeding.
Separate confirmed facts from reasonable inference.
Use cases
For the moments when code has more history than comments.
Unpack old guards, workarounds, and compatibility paths.
Map the evidence before removing or simplifying behavior.
Learn a new project through the choices embedded in its history.
Follow an incident back to its fix and the test that protects it.
Trust and boundaries
Built to investigate, not to act on your repository.
The current version works with public GitHub repositories only.
RepoLore makes no repository writes and never executes repository code.
Source URLs are included; confirmed facts are separated from inference. RepoLore cannot guarantee code is safe to remove.

FAQ
Answers for a careful workflow.
Does RepoLore modify my repository?
No. RepoLore is read-only and does not write to repositories, execute repository code, or create commits.
Does it support private repositories?
No. The current version is designed for public GitHub repositories.
Is RepoLore the same as git blame?
No. Git blame identifies a line's last change; RepoLore traces the surrounding history and related evidence to help explain the decision.
Can RepoLore guarantee that code is safe to remove?
No. It can surface evidence and risks, but a change still needs appropriate review and validation.
What information does RepoLore process?
It processes the public repository reference and the investigation details needed to retrieve public GitHub history. See the Privacy Policy for specifics.
Where does the evidence come from?
Evidence comes from publicly available GitHub repository history, including commits, pull requests, issues, patches, and tests.
