Long-term memory for AI-coded codebases.
A git blame for AI agents — but for the why, not just which line which
model touched. Captured live, by the agent, as the change happens.
Selvedge is a local MCP server. AI coding agents (Claude Code, Cursor,
Copilot) call it as they work to log structured change events with
reasoning. Your data stays in a SQLite file under .selvedge/ next to
your code.
Six months ago, your AI agent added a column called user_tier_v2. You don't
know why. git blame points to a commit from claude-code with a generated
message that says "Update schema." The session that made the change is long
gone — and so is the prompt that produced it.
With Selvedge, you run this instead:
$ selvedge blame user_tier_v2
user_tier_v2

Commit 3e7a991
Reasoning User asked to add a grandfathering flag for legacy free-tier
users during the pricing migration. Stores the original tier
so we can backfill discounts without touching billing history.
