Koda

Verification and memory for coding-agent workflows. Install once, verify the changes that matter, remember what keeps breaking.

1,000+ downloads on Open VSX — Koda is already watching commits in editors around the world.

Why Koda exists

Coding agents write features in minutes — but who verifies every commit? Full test suites are too slow to run per commit, so most verification happens late (or never). Koda closes that gap: on every commit it verifies only what changed, in seconds-to-minutes, and remembers what keeps breaking so your agent stops reintroducing old bugs.

Koda never writes code. It orchestrates verification, remembers patterns, and reports — to both the human and the agent.

The three surfaces

How it works — the pipeline

git commit
   │
   ▼
pre-commit ── secret guard (blocks committed API keys / private keys)
   │
   ▼
post-commit ── koda run (background, never blocks you)
   │
   ▼
1. Read diff ──────────── classify files: api / page / component / lib / config / test
2. Impact analysis ────── agent-supplied (MCP) → Groq fallback → deterministic heuristics
3. Kane browser flows ─── headless, scoped to changed UI only (page/component changes)
4. Endpoint checks ────── GET / HEAD / OPTIONS only; regressions flagged (200 → 500)
5. Integration tests ──── Jest / Vitest / Mocha / node:test, matched to changed files
6. Report ─────────────── JSON (agent-readable) + Markdown (human-readable)
7. Memory ─────────────── recurring patterns, resolution history, time-to-fix

Most commits never launch a browser: API/config/test-only changes verify with endpoints + tests in seconds. Browser flows fire only when UI files change.

Quick start

npm install -g koda-verify
cd your-project
koda init        # creates .koda/, installs git hooks, detects your app's port
koda doctor      # verifies: git, config, Kane CLI, target URL, directories

Then just keep committing — verification runs in the background on every commit.

One-time browser setup (optional, per user)

Browser flows are powered by the Kane CLI. The IDE extension onboards it for you: click Enable and Koda offers to install Kane and connect your account. Or do it manually:

npm install -g @testmuai/kane-cli
kane-cli login --oauth        # opens your browser — use (or create) YOUR OWN Kane account

About Kane accounts — yours, not ours

Koda ships zero credentials. Every Koda user authenticates their own Kane account:
