Features
特性
Built for long, cheap sessions.为长会话、低成本而生。
01
Cache-first loop
缓存优先循环
Append-only history aligned to DeepSeek's prefix cache. 90%+ hit on long sessions; input tokens bill at ~1/5.
append-only 历史对齐 DeepSeek prefix-cache。长会话 90%+ 命中,输入 token 约 1/5 计费。
02
Single Go binary
单个 Go 二进制
CGO-free, cross-compiled for darwin/linux/windows × amd64/arm64. No Node runtime.
无 CGO,交叉编译覆盖 darwin/linux/windows × amd64/arm64。运行不需要 Node。
03
MCP first-class
stdio, SSE, streamable HTTP. External servers merge their tools into one registry under a prefix.
stdio、SSE、streamable HTTP。外部服务器的工具以前缀合并进同一 registry。
04
Plan mode + sandbox
计划模式 + 沙箱
Writers are jailed to the workspace; /plan gates the session read-only until you approve.
写工具被关进工作区;/plan 进只读门,批准前不写盘。
05
Subagents & skills
子智能体与技能
explore / research / review / security-review agents, plus Markdown skill scripts with isolated tools.
explore / research / review / security-review 子智能体,加 Markdown 技能脚本与隔离工具。
06
Terminal-native
终端原生
Not another IDE plugin. git diff handles diffs, ls handles trees — the terminal is the workspace.
不是又一个 IDE 插件。diff 交给 git diff —— 终端就是工作面板。
Why DeepSeek
为何 DeepSeek
The cheapness is the point.便宜,就是核心。
Most agents pay full price for the same growing prompt every turn. Reasonix keeps the prefix byte-identical so DeepSeek's cache does the heavy lifting.多数 agent 每回合都为同一段不断增长的 prompt 付全价。Reasonix 让前缀逐字节稳定,让 DeepSeek 的缓存替你扛下来。
