Trunk

Verified 19 Aug 2026

Unified linters, formatters, and CI flakiness as a merge gate.

Trunk wraps linters, formatters, and related CI into a single developer tool (Check, Merge, Flaky Tests). It is verification infrastructure. AI features are secondary to “make the gate runnable.”

Editorial take

Trunk is a paved road for deterministic gates. Agents should run `trunk check`, not a random subset of linters. That alone improves factories. It is not an LLM reviewer.

Strengths

One invocation for many linters/formatters.
Flaky test and merge products for CI-shaped factories.
Works locally and in CI.

Limitations

Vendor-shaped wrapper around tools you could run yourself.
Not an agent.
Pricing is mixed and will rot.
