CODE REVIEWBUILT LIKE AMACHINE SHOP.

Bolt reads pull requests like a senior engineer who slept — finds the load-bearing failure, drafts the fix, routes it to the right human. Lint nits are suppressed by default.

What Bolt
actually does.

Bolt is opinionated about scope. It owns four jobs across the review surface — the rest stays human, by design.

01Pull request triage

Reads the PR like a senior who slept.

Bolt opens 1,400-line diffs, finds the load-bearing failure, and tags the file that breaks first. No 'consider extracting this'.

TTFC trend
02Blast-radius mapping

Maps every caller before you merge.

A diff that touches one helper surfaces the 28 routes that depend on it — across services, in your repos and your vendor's, with line numbers.

03Autofix queue

Drafts the fix; the human signs.

Mechanical issues — null checks, leaked descriptors, wrong context — get a queued patch you accept or reject. No drive-by commits.

04Ownership graph

Routes review to the engineer who knows.

Bolt knows who last touched which subsystem, who's on call, and who's out. The right reviewer is assigned without an algorithm meeting.

Sharp questions
deserve sharp answers.

Only when explicitly approved. Autofix patches sit in a queue your engineer signs. Bolt never pushes drive-by commits, force-pushes, or amends history. The PR title 'fix(autofix)' has a human author.

Through a read-only GitHub / GitLab / Bitbucket app. Code stays in your VCS — Bolt indexes locally on a dedicated tenancy. Nothing leaves your region. SOC 2 Type II and ISO 27001 are in scope today.

Cross-file invariants, leaked descriptors, races in async paths, fixture drift, vendor-version mismatches and the 'this used to work' class of regressions. The lint nits are explicitly suppressed.

Yes. Bolt accepts a YAML ruleset that maps repo-specific patterns to severity. Rulesets are versioned and replayable against historical PRs to test before rollout.

Per-PR pricing punishes teams that ship. Per-developer pricing is predictable and aligns with the value Bolt delivers — fewer review cycles, more shipped diffs.
