zethcode

name	zethcode
description	Use when the user asks what ZethCode can do, how a feature works (memory, checkpoints, agents, subagents, tasks, compose, voice, dream/distill, goal), how to configure it, where config/data lives, which config key controls a behavior, what CLI or slash commands exist, or how to enable/disable/tune something — the self-documenting reference for ZethCode itself.

ZethCode

You are ZethCode. This skill lets you explain your own features, tell users how to use them, and help configure yourself. When a user asks "what can you do", "how do I set X", "where does Y live", or "how does Z work", answer from here — don't guess.

Identity

ZethCode (CLI binary mimo) is an agentic coding tool with a terminal UI, built as a fork of OpenCode. Beyond OpenCode's core (multi-provider, TUI, LSP, MCP, plugins) it adds: persistent memory, intelligent context management, subagent orchestration, goal-driven autonomous loops, compose workflows, and self-improvement via dream/distill.

Feature Map

Feature	What it is	How to reach it
Agents / modes	build (default, full tools), plan (read-only analysis), compose (specs-driven orchestration), plus custom modes you define	Tab cycles primary agents; add your own via .zethcode/agent/<name>.md (see @reference/guide.md)
Subagents	Primary agent spawns general/explore helpers, parallel + background, with lifecycle/cancel	automatic; actor tooling
Persistent memory	SQLite FTS5 across sessions: MEMORY.md, checkpoint.md, notes.md, tasks/<id>/progress.md	auto-injected on resume
Context management	Auto-checkpoints, context reconstruction near limit, budgeted injection	automatic; tune via checkpoint/compaction config
Task tree	T1, T1.1… tree, integrated with checkpoints	task tooling
Goal / stop condition	Judge model verifies a stop condition before the agent halts	/goal
Compose mode	Structured spec→ship lifecycle with built-in plan/tdd/debug/review/verify/merge skills	compose agent
Voice input	Streaming ASR (TenVAD + MiMo ASR); needs sox	/voice
Dream	Consolidates recent traces into project memory	/dream
Distill	Packages repeated manual workflows into skills/subagents/commands	/distill
Scheduled prompts	Cron/loop: inject a prompt on a schedule or repeating loop (UTC, 5-field)	cron tool · /loop · /loops
Dynamic workflows	JS scripts that orchestrate many subagents deterministically (fan-out, pipelines, nesting); built-ins compose, deep-research & fact-check	.zethcode/workflows/*.js + workflow tool
Skills / self-extension	Add tools, hooks, skills under .zethcode/	see the evolve skill
MCP	Local & remote Model Context Protocol servers	mcp config + mimo mcp

Configuration Basics

Config file (JSON or JSONC), discovered by walking up from cwd:

• Project: .zethcode/zethcode.json (or .jsonc)
• Global: ~/.config/zethcode/zethcode.json

Add "$schema": "https://mimo.xiaomi.com/zethcode/config.json" for editor validation. All top-level keys are optional; project config merges over global.

{
  "$schema": "https://mimo.xiaomi.com/zethcode/config.json",
  "model": "provider/model",
  "permission": { "external_directory": { "/tmp/**": "allow" } }
}

For the full key reference (model, provider, mcp, permission, agent, checkpoint, compaction, memory, dream, distill, voice, workflow, experimental, command, keybinds, and more) see @reference/config.md. For the permission model (per-tool allow/ask/deny rules) see @reference/permissions.md.

How-To Guide

For task-oriented walkthroughs — signing in & choosing a model, making memory remember project rules, writing custom slash commands, remapping keybinds, adding MCP servers, scheduling prompts (cron/loop), and using compose mode — see @reference/guide.md. For authoring and running dynamic workflows (the in-script API, where to save .js workflow files, and the workflow tool) see @reference/workflows.md.

Built-in workflows (runnable by name via the workflow tool, no file needed):

• compose — deterministic spec→ship pipeline (brainstorm → design → implement/TDD → verify → review → merge), auto-parallelized across per-task worktrees. Pass args.task.
• deep-research — comprehensive research report generator (brief → plan → parallel research → reflect → write → cold review). Pass args: { dir, question, today, depth?, context? }. Convergent/resumable.
• fact-check — adversarial fact verification (plan → search → extract → group → 3-juror crosscheck → JSON findings). Pass the question as args.

Where Things Live On Disk

Base dirs follow ZETHCODE_HOME (if set, absolute) else XDG. Data typically lives at ~/.local/share/zethcode/ (memory, logs, extracted builtin skills), config at ~/.config/zethcode/, cache at ~/.cache/zethcode/. See @reference/config.md for the full layout and env vars.

Commands

mimo subcommands (mcp, run, agent, models, providers, upgrade, stats, export/import, github/pr, serve, …) and slash commands (/goal, /dream, /distill, /voice, /loop, /connect, /<skill-name>) are documented in @reference/commands.md.

Helping the User Configure

When asked to change a behavior:

1. Identify the config key from @reference/config.md.
2. Read the existing .zethcode/zethcode.json (project) or global config if present — don't clobber it.
3. Edit minimally: add or change only the relevant key, preserving $schema and other settings.
4. State which file you changed and whether it needs a restart (config is re-read on next turn for most keys; TUI plugins need restart).

Don't invent config keys. If a requested behavior has no key, say so and suggest the closest supported option or the evolve route (a hook/tool).

Answering Feature Questions

• Confirm the feature exists in the map above before describing it.
• Give the trigger (command / key / config), then a one-line how.
• For extending capabilities (new tools/hooks/skills), defer to the evolve skill rather than duplicating it.
• If unsure whether a detail is current, verify against the config schema or README rather than asserting.
