Features

What it does

Plan / Edit / Auto modes

Plan mode blocks all mutating tools for safe research. Edit mode prompts per call. Auto mode approves everything for trusted tasks.

Live task panel

For multi-step work, the agent publishes a task list with progress icons, elapsed time, and token deltas. Multi-step work feels managed.

Image understanding

Drop image paths (PNG, JPG, WebP, GIF, BMP up to 5 MB) into any prompt. The model sees them inline — perfect for UI reviews, diagrams, and screenshots.

Extensible JSON themes

Fully customizable color palettes with WCAG contrast validation. Pick from built-in presets or define your own. Live preview with Ctrl+T.

Web search, GitHub, and headless browser

Research the web, read GitHub repos, and fetch JavaScript-rendered pages — all without leaving your terminal.

LSP semantic code intelligence

Hover, go-to-definition, references, and diagnostics via Language Server Protocol. Auto-configured per project with an interactive wizard.

Turn supervisor with tiered skills

The agent picks the right skill depth for the task — from quick edits to deep research — with graceful preemption and visible TUI indicators.

Streaming reasoning

Toggle the model's chain-of-thought with /reasoning or Ctrl-R. See how it thinks in real time.

Session persistence

Every turn is auto-saved. /resume lists past sessions with message counts in a paginated picker. Never lose your place.

Smart permissions

Bash session-allow is keyed by the first token (allow all git commands). Write/edit show a unified diff before you approve.

262K context window

Read entire modules, large configs, and full stack traces without the model losing track. Direct to Cloudflare — no middleman.

MCP server integration

Plug in external tools via the Model Context Protocol — local stdio servers or remote SSE endpoints. GitHub, Sentry, docs search, databases, and more.

Kimiflare Cloud mode

Device auth — no API key needed. Get started in seconds with a managed proxy and real-time token budget tracking. 5 million free tokens until May 14, 2026.

Explicit cross-session memory

The agent never surveils your conversation. Memories are stored only when you ask — via remember, recall, and forget tools — with SQLite + embeddings for durable, privacy-respecting retrieval across sessions.
