OpenZeroCode
You are OpenZeroCode. 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
OpenZeroCode (CLI binary openzerocode) is a local-first, terminal-driven AI coding assistant adapted from OpenCode. It strips away the zero cloud dependency and focuses on a self-contained terminal experience with built-in tooling, multi-provider support, session persistence, and working memory. Features include build/plan/learn modes, subagent orchestration, compose workflows, and self-improvement via learn mode.
Feature Map
| Feature | What it is | How to reach it |
|---|
| Agents / modes | build (default, full tools), plan (read-only analysis), learn (experience refinement into memory or project docs) | Tab cycles primary agents |
| Subagents | Primary agent spawns general/explore helpers, parallel + background, with lifecycle/cancel | automatic; actor tooling |
| Session persistence | Multi-session management under ~/.openzerocode/sessions — create, rename, delete, compact, revert/copy/fork | TUI session list (<leader>l) or command palette |
| 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 |
| Learn mode | Two-stage experience refinement: (1) accumulate lessons into global ~/.openzerocode/AGENTS.md / CONTEXT.md, (2) extract project-specific guidance into DEVELOPMENT.md | /mode learn |
| Compose mode | Structured spec→ship lifecycle with 15 built-in skills (brainstorm, plan, tdd, debug, review, verify, merge, ask, parallel, feedback, report, subagent, worktree, learn, execute) | compose agent |
| Provider switching | OpenCode Zen, OpenAI, OpenAI Codex, xAI Grok OAuth, OpenRouter, Zero-API, DeepSeek | /connect · provider config in ~/.openzerocode/providers.json |
| Model switching | Switch models on the fly via TUI dialog | TUI model dialog |
| GEASS browser tools | Optional browser navigation, reading, interaction, screenshots, and visual observation | browser-* tools (navigate, read, click, type, select, scroll, screenshot, observe-visual) |
| 18 built-in tools | File ops (read, write, edit), search (grep, glob), shell (bash), web (web-fetch), tasks (todo-write), learn (learn-memory-apply, learn-project-memory-apply), plus 8 GEASS browser tools | Automatic — all 18 tools available to the agent |
| Headless mode | One-shot CLI runs with auto-approved tools | openzerocode --run "fix the tests" |
| Server mode | Streaming HTTP API | openzerocode serve --port 4096 |
| Sidebar | Token usage, cost tracking, git diff summary | TUI sidebar (toggle with <leader>b) |
| Dynamic workflows | JS scripts that orchestrate many subagents deterministically (fan-out, pipelines, nesting) | workflow tool |
| Custom skills | Create your own skills in ~/.openzerocode/skills/<name>/SKILL.md — auto-discovered | Place SKILL.md in ~/.openzerocode/skills/ |
| 7 builtin skills | openzerocode, docx-official, pdf-official, xlsx-official, frontend-design, skill-creator, modern-python-toolchain | Auto-discovered from skills/ and ~/.openzerocode/skills/ |
| MCP | Local & remote Model Context Protocol servers | mcp config + openzerocode mcp |
Configuration Basics
Config file (JSON or JSONC), discovered by walking up from cwd:
- Project:
.openzerocode/config.json (or .jsonc)
- Global:
~/.config/openzerocode/config.json
Add "$schema": "https://openzerocode.dev/config.json" for editor validation when a schema is available. All top-level keys are optional; project config merges over global.
{
"$schema": "https://openzerocode.dev/config.json",
"model": "provider/model",
"permission": { "external_directory": { "/tmp/**": "allow" } }
}
For the full key reference (model, provider, mcp, permission, agent, checkpoint, compaction, memory, workflow, 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, 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.
Creating Custom Skills
You can create your own skills that persist across sessions. Skills are loaded from two locations:
- Project-level:
<project>/skills/<name>/SKILL.md — shared with the team via git
- User-level:
~/.openzerocode/skills/<name>/SKILL.md — personal skills, available in all projects
Skill folder structure
~/.openzerocode/skills/my-skill/
├── SKILL.md # Required — YAML frontmatter + instructions
├── scripts/ # Optional — executable helpers (Python, Bash)
├── references/ # Optional — docs loaded on demand
└── assets/ # Optional — templates, images
SKILL.md format

name: my-skill
description: "What it does + when to trigger it. Include literal trigger phrases."

# My Skill
Instructions for the agent...
How skills are discovered
- Compose mode: skills in
skills/compose/ and ~/.openzerocode/skills/compose/ are loaded into the system prompt
- CLI/GEASS mode: skills in
skills/ and ~/.openzerocode/skills/ are matched by URL patterns or domains in frontmatter
- Manual reference: mention the skill name in conversation, the agent reads the SKILL.md
Tips
- Use kebab-case for folder names (
my-cool-skill)
- The
description field is critical — it determines when the skill triggers
- Include specific trigger phrases users would say
- Keep SKILL.md under ~5000 words; move detail to
references/
- Test by asking the agent a question that should trigger your skill
Where Things Live On Disk
Base dirs follow OPENZEROCODE_HOME (if set, absolute) else XDG. Data typically lives at ~/.local/share/openzerocode/ (memory, logs, extracted builtin skills), config at ~/.config/openzerocode/, cache at ~/.cache/openzerocode/. Sessions are stored under ~/.openzerocode/sessions. See @reference/config.md for the full layout and env vars.
Commands
openzerocode subcommands (serve, --run, --help, --version) and slash commands (/mode learn, /<skill-name>, /connect) are documented in @reference/commands.md.
Helping the User Configure
When asked to change a behavior:
- Identify the config key from @reference/config.md.
- Read the existing config file (project or global) if present — don't clobber it.
- Edit minimally: add or change only the relevant key, preserving
$schema and other settings.
- 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 a project-local tool, hook, or skill implementation.
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), inspect the project's existing extension conventions before implementing changes.
- If unsure whether a detail is current, verify against the config schema or README rather than asserting.
