What’s new · Verified Autopilot checkpoint

Plan it. Prove it. Know the gaps.

The latest local IDE and CLI checkpoint turns a plain-language request into a durable plan, an isolated change, and a reviewable proof record—while keeping uncertainty and missing evidence visible.

Verified Autopilot checkpoint July 2026 · Local IDE + CLI

01 Intent

02 Action

03 Evidence

04 Claim

ProofGraph + Change Passport

See the chain behind every conclusion.

Tasks now write a local, hash-chained record of contracts, actions, evidence, claims, and known gaps. The resulting capsule and Change Passport make the outcome reviewable and replayable.

Local-first Hash-chained Gap-aware

Isolated ProofPatch

Model edits land in a staged workspace first. Preview, publish, discard, or roll back without silently overwriting concurrent work.

Action / Abstention Gate

Bounded discovery must justify an edit before mutation. “Already satisfied” is a valid, evidenced outcome—not a failed task.

One durable Task Workspace

Intent Mirror, executable plans, approvals, evidence, patch review, rollback, and task history now stay attached to one resumable local task.

Kimi K3, verified in the loop

A live moonshotai/kimi-k3 run proved exact command approval, attended containment labels, honest no-change abstention, and bounded follow-up evidence reuse.

Proof, shipping, and release foundations

CLI and local API flows expose durable planning, proof export, verified caching, causal runs, semantic merge forecasts, and structured GitHub or Cloudflare shipping preflights.

Built for the difficult 10%

More than another chat box.

Krater Pro combines deliberate model choice, real tools, durable project context, and cost-aware execution into one opinionated coding environment.

⌁

Smart Coding Router

Let Krater Pro weigh task complexity, accuracy needs, and cost before choosing a model—or pin Kimi K3 yourself when you know what you want.

◎

Agentic by design

Plan, inspect, edit, run, verify, and recover in a tight loop—with workspace boundaries and human-readable actions.

↻

Context without the tax

Prompt caching, reusable context, bounded search, and usage telemetry keep long sessions focused and cost-conscious.

⌘

Language-native judgment

Structured playbooks cover mainstream, systems, functional, data, mobile, infrastructure, and hardware languages.

✓

Benchmarked in the open

A 100-task expert suite plus adapters for DeepSWE, SWE-bench Pro, and SWE-Atlas make validation reproducible—not hand-wavy.

One agent, where you work

Start light. Go all the way.
