TERMINAL-NATIVE · POWERED BY ANTHROPIC

An autonomous engineering agent that treats your terminal as the product.

KHAELOR reads, searches, edits, runs, and verifies code in your repository — streaming every action into a calm, fast, keyboard-native interface. No web UI. No Electron. Just your terminal, done properly.

$ curl -fsSL https://www.khaelor.sh/install.sh | sh

Why KHAELOR

❯_

The terminal is the product

Print-once scrollback, a bounded flicker-free live region, sub-16 ms input echo. Native selection and copy always work — nothing repaints behind your back.

▶▶

First-class streaming

Everything is event-driven — model text, tool calls, process output — coalesced into smooth 16 ms frames. No spinners pretending to be progress.

Seven powerful tools

read · write · edit (9-strategy replacer) · grep · glob · bash · process — a real background process manager, not blocking shells.

●○

Background processes

Start a dev server, keep editing, read its output later, run tests alongside. Long commands migrate to the background instead of hanging the agent.

⋮

Capability-based permissions

Allow / ask / deny by capability — never opaque tool names. Approve once with Enter, persist a precise grant with A, deny with Esc.

↻

Persistent sessions

Every session is an append-only event log. Resume is replay: your transcript, cost, file state, and even pending permission prompts survive restarts.

Honest numbers

Token usage, cost, and context pressure come from real API metadata — never estimates, never invented progress bars. If pricing is unknown, it says n/a.

⊕

Context engine

Token-pressure-aware compaction with structured checkpoints. Inspect exactly what the model sees with /context; compact on demand with /compact.

✎

Steer while it works

Type while the agent runs — messages queue and inject safely at tool boundaries. Esc interrupts instantly without corrupting the session.

Install

One line (checks Node ≥ 22, installs the CLI globally, verifies it):

curl -fsSL https://www.khaelor.sh/install.sh | sh

Or install the tarball directly with npm:

npm install -g https://www.khaelor.sh/khaelor.tgz

Then set your Anthropic API key and start it inside any project:

export ANTHROPIC_API_KEY=sk-ant-...
khaelor
