Your agent shipped a bug.
Ghost shows you which prompt did it.
GhostInTheCodebase is a black-box recorder for AI coding agents. It captures every turn, watches the app at runtime, attributes the regression to the exact prompt — then rewinds the file in one click.
agent-agnostic · no SDK · no agent cooperation required
Module-level Map cache with no eviction policy.
TestSprite tells you the PR is red.
Every pull request gets a verdict. It catches the regression before it merges — but the verdict is a symptom, not a cause.
Ghost tells you which prompt turned it red.
The turn, the diff, the metric that moved, and the file to roll back. Different layer of the same loop — behind the maker, not the merge.
Three verbs. One repeat.
Record what happened, attribute the regression, reverse the damage. Then the agent tries again — with the autopsy in hand.
Record
A shadow git commit per change burst. Runtime metrics sampled straight from the app. Nothing is installed into your agent.
passiveAttribute
Thresholds catch the spike, trend slope separates a leak from a busy minute, and a per-turn bisect names the prompt that introduced it.
autopsyReverse
Roll the blamed turn back, re-measure, and watch the curve flatten. The fix prompt is one click from the clipboard.
time travelBuilt to be trusted when the agent is not.
Every claim in the dashboard comes from something Ghost observed — files on disk, memory in the process, responses from the app.
Black-box recorder
Shadow git commits every change burst, so the timeline is built from what actually landed on disk — not from what an agent says it did.
Autopsy engine
Four signal types — memory, CPU, latency, error rate — plus a slope test that tells a leak from a load spike, attributed to a single turn.
3D code city
Modules become districts, files become towers, imports become arcs. AI-written code glows amber, unreviewed code sits under fog.
One-click rollback
Restore the blamed file to the commit before the regression, then watch the metric line drop back to baseline in the same view.
Agent-agnostic
Cursor, Claude Code, Codex, OpenCode, or a human with a keyboard. Ghost watches the filesystem and the process, so it never needs an integration.
TestSprite-native
The live API is covered by a TestSprite suite that runs on every pull request, so the regression guard keeps working after the demo ends.
Replay a real autopsy.
Seven turns, one unbounded cache, one heal. Scrub the timeline, read the diff, rotate the city, and copy the fix prompt.
