User config (`.jsonc` preferred over `.json`): | Platform | Path | | ----------- | ----------------------------------------- | | macOS/Linux | `~/.config/opencode/oh-my-openagent.jsonc` | | Windows | `%APPDATA%\opencode\oh-my-openagent.jsonc` | JSONC supports `// line comments`, `/* block comments */`, and trailing commas. Enable schema autocomplete: ```json { "$schema": "https://raw.githubusercontent.com/code-yeongyu/oh-my-openagent/dev/assets/oh-my-openagent.schema.json" } ``` Run `bunx oh-my-openagent install` for guided setup. Run `opencode models` to list available models. ### Quick Start Example Here's a practical starting configuration: ```jsonc { "$schema": "https://raw.githubusercontent.com/code-yeongyu/oh-my-openagent/dev/assets/oh-my-openagent.schema.json", "agents": { // Main orchestrator: Claude Opus or Kimi K2.5 work best "sisyphus": { "model": "kimi-for-coding/k2p5", "ultrawork": { "model": "anthropic/claude-opus-4-6", "variant": "max" }, }, // Research agents: cheap fast models are fine "librarian": { "model": "google/gemini-3-flash" }, "explore": { "model": "github-copilot/grok-code-fast-1" }, // Architecture consultation: GPT-5.4 or Claude Opus "oracle": { "model": "openai/gpt-5.4", "variant": "high" }, // Prometheus inherits sisyphus model; just add prompt guidance "prometheus": { "prompt_append": "Leverage deep & quick agents heavily, always in parallel.", }, }, "categories": { // quick — trivial tasks "quick": { "model": "opencode/gpt-5-nano" }, // unspecified-low — moderate tasks "unspecified-low": { "model": "anthropic/claude-sonnet-4-6" }, // unspecified-high — complex work "unspecified-high": { "model": "anthropic/claude-opus-4-6", "variant": "max" }, // writing — docs/prose "writing": { "model": "google/gemini-3-flash" }, // visual-engineering — Gemini dominates visual tasks "visual-engineering": { "model": "google/gemini-3.1-pro", "variant": "high", }, // Custom category for git operations "git": { "model": "opencode/gpt-5-nano", "description": "All git operations", "prompt_append": "Focus on atomic commits, clear messages, and safe operations.", }, }, // Limit expensive providers; let cheap ones run freely "background_task": { "providerConcurrency": { "anthropic": 3, "openai": 3, "opencode": 10, "zai-coding-plan": 10, }, "modelConcurrency": { "anthropic/claude-opus-4-6": 2, "opencode/gpt-5-nano": 20, }, }, "experimental": { "aggressive_truncation": true, "task_system": true }, "tmux": { "enabled": false }, } ``` --- ## Core Concepts ### Agents Override built-in agent settings. Available agents: `sisyphus`, `hephaestus`, `prometheus`, `oracle`, `librarian`, `explore`, `multimodal-looker`, `metis`, `momus`, `atlas`. ```json { "agents": { "explore": { "model": "anthropic/claude-haiku-4-5", "temperature": 0.5 }, "multimodal-looker": { "disable": true } } } ``` Disable agents entirely: `{ "disabled_agents": ["oracle", "multimodal-looker"] }` #### Agent Options | Option | Type | Description | | ----------------- | ------------- | ------------------------------------------------------ | | `model` | string | Model override (`provider/model`) | | `fallback_models` | string\|array | Fallback models on API errors | | `temperature` | number | Sampling temperature | | `top_p` | number | Top-p sampling | | `prompt` | string | Replace system prompt | | `prompt_append` | string | Append to system prompt | | `tools` | array | Allowed tools list | | `disable` | boolean | Disable this agent | | `mode` | string | Agent mode | | `color` | string | UI color | | `permission` | object | Per-tool permissions (see below) | | `category` | string | Inherit model from category | | `variant` | string | Model variant: `max`, `high`, `medium`, `low`, `xhigh` | | `maxTokens` | number | Max response tokens | | `thinking` | object | Anthropic extended thinking | | `reasoningEffort` | string | OpenAI reasoning: `low`, `medium`, `high`, `xhigh` | | `textVerbosity` | string | Text verbosity: `low`, `medium`, `high` | | `providerOptions` | object | Provider-specific options | #### Anthropic Extended Thinking ```json { "agents": { "oracle": { "thinking": { "type": "enabled", "budgetTokens": 200000 } } } } ``` #### Agent Permissions Control what tools an agent can use: ```json { "agents": { "explore": { "permission": { "edit": "deny", "bash": "ask", "webfetch": "allow" } } } } ``` | Permission | Values | | -------------------- | --------------------------------------------------------------------------- | | `edit` | `ask` / `allow` / `deny` | | `bash` | `ask` / `allow` / `deny` or per-command: `{ "git": "allow", "rm": "deny" }` | | `webfetch` | `ask` / `allow` / `deny` | | `doom_loop` | `ask` / `allow` / `deny` | | `external_directory` | `ask` / `allow` / `deny` | ### Categories Domain-specific model delegation used by the `task()` tool. When Sisyphus delegates work, it picks a category, not a model name. #### Built-in Categories | Category | Default Model | Description | | -------------------- | ------------------------------- | ---------------------------------------------- | | `visual-engineering` | `google/gemini-3.1-pro` (high) | Frontend, UI/UX, design, animation | | `ultrabrain` | `openai/gpt-5.4` (xhigh) | Deep logical reasoning, complex architecture | | `deep` | `openai/gpt-5.3-codex` (medium) | Autonomous problem-solving, thorough research | | `artistry` | `google/gemini-3.1-pro` (high) | Creative/unconventional approaches | | `quick` | `openai/gpt-5.4-mini` | Trivial tasks, typo fixes, single-file changes | | `unspecified-low` | `anthropic/claude-sonnet-4-6` | General tasks, low effort | | `unspecified-high` | `anthropic/claude-opus-4-6` (max) | General tasks, high effort | | `writing` | `google/gemini-3-flash` | Documentation, prose, technical writing | > **Note**: Built-in defaults only apply if the category is present in your config. Otherwise the system default model is used. #### Category Options | Option | Type | Default | Description | | ------------------- | ------------- | ------- | ------------------------------------------------------------------- | | `model` | string | - | Model override | | `fallback_models` | string\|array | - | Fallback models on API errors | | `temperature` | number | - | Sampling temperature | | `top_p` | number | - | Top-p sampling | | `maxTokens` | number | - | Max response tokens | | `thinking` | object | - | Anthropic extended thinking | | `reasoningEffort` | string | - | OpenAI reasoning effort | | `textVerbosity` | string | - | Text verbosity | | `tools` | array | - | Allowed tools | | `prompt_append` | string | - | Append to system prompt | | `variant` | string | - | Model variant | | `description` | string | - | Shown in `task()` tool prompt | | `is_unstable_agent` | boolean | `false` | Force background mode + monitoring. Auto-enabled for Gemini models. | Disable categories: `{ "disabled_categories": ["ultrabrain"] }` ### Model Resolution 3-step priority at runtime: 1. **User override** — model set in config → used exactly as-is 2. **Provider fallback chain** — tries each provider in priority order until available 3. **System default** — falls back to OpenCode's configured default model #### Agent Provider Chains | Agent | Default Model | Provider Priority | | --------------------- | ------------------- | ---------------------------------------------------------------------------- | | **Sisyphus** | `claude-opus-4-6` | `claude-opus-4-6` → `glm-5` → `big-pickle` | | **Hephaestus** | `gpt-5.3-codex` | `gpt-5.3-codex` → `gpt-5.4` (GitHub Copilot fallback) | | **oracle** | `gpt-5.4` | `gpt-5.4` → `gemini-3.1-pro` → `claude-opus-4-6` | | **librarian** | `gemini-3-flash` | `gemini-3-flash` → `minimax-m2.5-free` → `big-pickle` | | **explore** | `grok-code-fast-1` | `grok-code-fast-1` → `minimax-m2.5-free` → `claude-haiku-4-5` → `gpt-5-nano` | | **multimodal-looker** | `gpt-5.3-codex` | `gpt-5.3-codex` → `k2p5` → `gemini-3-flash` → `glm-4.6v` → `gpt-5-nano` | | **Prometheus** | `claude-opus-4-6` | `claude-opus-4-6` → `gpt-5.4` → `gemini-3.1-pro` | | **Metis** | `claude-opus-4-6` | `claude-opus-4-6` → `gpt-5.4` → `gemini-3.1-pro` | | **Momus** | `gpt-5.4` | `gpt-5.4` → `claude-opus-4-6` → `gemini-3.1-pro` | | **Atlas** | `claude-sonnet-4-6` | `claude-sonnet-4-6` → `gpt-5.4` | #### Category Provider Chains | Category | Default Model | Provider Priority | | ---------------------- | ------------------- | -------------------------------------------------------------- | | **visual-engineering** | `gemini-3.1-pro` | `gemini-3.1-pro` → `glm-5` → `claude-opus-4-6` | | **ultrabrain** | `gpt-5.4` | `gpt-5.4` → `gemini-3.1-pro` → `claude-opus-4-6` | | **deep** | `gpt-5.3-codex` | `gpt-5.3-codex` → `claude-opus-4-6` → `gemini-3.1-pro` | | **artistry** | `gemini-3.1-pro` | `gemini-3.1-pro` → `claude-opus-4-6` → `gpt-5.4` | | **quick** | `gpt-5.4-mini` | `gpt-5.4-mini` → `claude-haiku-4-5` → `gemini-3-flash` → `minimax-m2.5` → `gpt-5-nano` | | **unspecified-low** | `claude-sonnet-4-6` | `claude-sonnet-4-6` → `gpt-5.3-codex` → `gemini-3-flash` | | **unspecified-high** | `claude-opus-4-6` | `claude-opus-4-6` → `gpt-5.4 (high)` → `glm-5` → `k2p5` → `kimi-k2.5` | | **writing** | `gemini-3-flash` | `gemini-3-flash` → `claude-sonnet-4-6` | Run `bunx oh-my-openagent doctor --verbose` to see effective model resolution for your config. --- ## Task System ### Background Tasks Control parallel agent execution and concurrency limits. ```json { "background_task": { "defaultConcurrency": 5, "staleTimeoutMs": 180000, "providerConcurrency": { "anthropic": 3, "openai": 5, "google": 10 }, "modelConcurrency": { "anthropic/claude-opus-4-6": 2 } } } ``` | Option | Default | Description | | --------------------- | -------- | --------------------------------------------------------------------- | | `defaultConcurrency` | - | Max concurrent tasks (all providers) | | `staleTimeoutMs` | `180000` | Interrupt tasks with no activity (min: 60000) | | `providerConcurrency` | - | Per-provider limits (key = provider name) | | `modelConcurrency` | - | Per-model limits (key = `provider/model`).

Built-in skills: `playwright`, `playwright-cli`, `agent-browser`, `dev-browser`, `git-master`, `frontend-ui-ux` Disable built-in skills: `{ "disabled_skills": ["playwright"] }` #### Skills Configuration ```json { "skills": { "sources": [ { "path": "./my-skills", "recursive": true }, "https://example.com/skill.yaml" ], "enable": ["my-skill"], "disable": ["other-skill"], "my-skill": { "description": "What it does", "template": "Custom prompt template", "from": "source-file.ts", "model": "custom/model", "agent": "custom-agent", "subtask": true, "argument-hint": "usage hint", "license": "MIT", "compatibility": ">= 3.0.0", "metadata": { "author": "Your Name" }, "allowed-tools": ["read", "bash"] } } } ``` | `sources` option | Default | Description | | ---------------- | ------- | ------------------------------- | | `path` | - | Local path or remote URL | | `recursive` | `false` | Recurse into subdirectories | | `glob` | - | Glob pattern for file selection | ### Hooks Disable built-in hooks via `disabled_hooks`: ```json { "disabled_hooks": ["comment-checker"] } ``` Available hooks: `todo-continuation-enforcer`, `context-window-monitor`, `session-recovery`, `session-notification`, `comment-checker`, `grep-output-truncator`, `tool-output-truncator`, `directory-agents-injector`, `directory-readme-injector`, `empty-task-response-detector`, `think-mode`, `anthropic-context-window-limit-recovery`, `rules-injector`, `background-notification`, `auto-update-checker`, `startup-toast`, `keyword-detector`, `agent-usage-reminder`, `non-interactive-env`, `interactive-bash-session`, `compaction-context-injector`, `thinking-block-validator`, `claude-code-hooks`, `ralph-loop`, `preemptive-compaction`, `auto-slash-command`, `sisyphus-junior-notepad`, `no-sisyphus-gpt`, `start-work`, `runtime-fallback` **Notes:** - `directory-agents-injector` — auto-disabled on OpenCode 1.1.37+ (native AGENTS.md support) - `no-sisyphus-gpt` — **do not disable**. It blocks incompatible GPT models for Sisyphus while allowing the dedicated GPT-5.4 prompt path. - `startup-toast` is a sub-feature of `auto-update-checker`. Disable just the toast by adding `startup-toast` to `disabled_hooks`. ### Commands Disable built-in commands via `disabled_commands`: ```json { "disabled_commands": ["init-deep", "start-work"] } ``` Available commands: `init-deep`, `ralph-loop`, `ulw-loop`, `cancel-ralph`, `refactor`, `start-work`, `stop-continuation`, `handoff` ### Browser Automation | Provider | Interface | Installation | | ---------------------- | --------- | --------------------------------------------------- | | `playwright` (default) | MCP tools | Auto-installed via npx | | `agent-browser` | Bash CLI | `bun add -g agent-browser && agent-browser install` | Switch provider: ```json { "browser_automation_engine": { "provider": "agent-browser" } } ``` ### Tmux Integration Run background subagents in separate tmux panes.

Disabled by default. ```json { "hashline_edit": true } ``` When enabled, two companion hooks are active: `hashline-read-enhancer` (annotates Read output) and `hashline-edit-diff-enhancer` (shows diffs). Opt-in by setting `hashline_edit: true`. Disable the companion hooks individually via `disabled_hooks` if needed. ### Experimental ```json { "experimental": { "truncate_all_tool_outputs": false, "aggressive_truncation": false, "auto_resume": false, "disable_omo_env": false, "task_system": false, "dynamic_context_pruning": { "enabled": false, "notification": "detailed", "turn_protection": { "enabled": true, "turns": 3 }, "protected_tools": [ "task", "todowrite", "todoread", "lsp_rename", "session_read", "session_write", "session_search" ], "strategies": { "deduplication": { "enabled": true }, "supersede_writes": { "enabled": true, "aggressive": false }, "purge_errors": { "enabled": true, "turns": 5 } } } } } ``` | Option | Default | Description | | ---------------------------------------- | ---------- | ------------------------------------------------------------------------------------ | | `truncate_all_tool_outputs` | `false` | Truncate all tool outputs (not just whitelisted) | | `aggressive_truncation` | `false` | Aggressively truncate when token limit exceeded | | `auto_resume` | `false` | Auto-resume after thinking block recovery | | `disable_omo_env` | `false` | Disable auto-injected `` block (date/time/locale).
