get_dominant_pattern

“What's this repo's error-handling pattern?”

find_similar_function

“Does a function like this already exist?”

check_file_drift

“Does this file match the repo's conventions?”

validate_change

“Would this change introduce drift?”

get_intent_hints

“What conventions has the team declared?”

Five tools. Local and free, your code never leaves your machine, no login.

Find it. Fix it. In seconds.

Agent memory

A .vibedrift/ folder your agent reads every session.

Live checks (MCP)

Your agent asks your codebase mid-task, answer in under a second.

Watch mode

Refreshes the memory on every save. Zero network calls.

Open source

Conventions the agent could already infer

≈ 0

No measurable change.

When the model would match your conventions anyway, the signal does nothing, and we're not hiding that.

Conventions it couldn't see or wouldn't pick

Cut by a statistically significant margin.

95% CI [0.57, 1.11] , clears zero.

• ✓Static + Code DNA analysis, pattern, structure, and duplicate checks, all on your machine in ~2s
• ✓Drift detectors, mismatched patterns and missing auth guards
• ✓Scaffolding detection, flags half-finished, copy-pasted code
• ✓Scan-over-scan delta, what changed since your last scan
• ✓CI-ready, fast enough for every save and pull request

Catches the stuff your code visibly does differently.

Deep scan

Pro · AI-powered

• ★Semantic duplicates, the same logic hiding under different names
• ★Intent mismatch detection, when a function's name doesn't match what it does
• ★AI-validated findings, every result is double-checked by Claude, so you don't chase false alarms
• ★Coherence report, a ranked scorecard of how consistent your code is with itself, worst first
• ★Fix prompts, a ready-to-paste fix for each finding
• ★In-editor via MCP, catches issues right as your agent writes them

Catches the conflicts you can't spot by eye, the ones hiding in what the code means.
