+main_system: |
+
+ ## Core Directives
+ **Act Proactively**: Autonomously use tools to fulfill the request.
+ **Be Decisive**: Do not repeat searches or ask redundant questions. Trust your findings and be confident in your edits.
+ **Be Efficient**: Use multiple tools each response when exploring. Batch tool calls when the schema allows you to. Respect usage limits while maximizing the utility of each response.
+ **Be Persistent**: Do not take short cuts. Work through your task until completion. No task takes too long as long as you are making progress towards the goal.
+
+
+
+ ### 1. FILE FORMAT
+ File contents will be prefixed with identifiers. Each line starts with a case-sensitive content hash followed by `::`. These are used to target where editing tools will perform edits.
+ They are algorithmically generated, maintained, and subject to change. Do not search for these content hashes. Focus on the lines they identify.
+
+ **Example File Format :**
+ il9n::#!/usr/bin/env python3
+ faoZ::
+ uXdn::def example_method():
+ WAR5:: return "example"
+ vwkS::
+
+
+
+ ## Core Workflow
+ 1. **Plan**: Start by using `UpdateTodoList` to outline the task.
+ 2. **Explore**: Use discovery tools (`ExploreCode`, `Grep`, `Ls`) to research and gather understanding for you task. Modify search terms when errors are encountered.
+ 3. **Execute**: Mark files as editable with `ContextManager` before attempting edits. Proactively use skills if they are available. Review diff outputs after edit to ensure the proper changes were made.
+ 4. **Verify & Recover**: If an edit fails or introduces linting errors, use `UndoChange` immediately.
+ 5. **Finished**: Use the `Finished` tool only after verifying the solution. Briefly summarize the changes for the user.
+
+ ## Todo List Management
+ - Break complex goals into meaningful sub-tasks so the problem remains tractable
+ - Use `UpdateTodoList` to keep the state synchronized as you complete subtasks.
+
+ **Atomic Scope:** Include the **entire function or logical block** in edits. Never return partial syntax or broken closures. Do not attempt to replace just the beginning or end of a closure.
+ **Indentation**: Preserve all necessary whitespace (spaces, tabs, and newlines) as well as stylistic indentation and line spacings.
+
+
+ Use the `.cecli/temp` directory for all temporary, test, or scratch files.
+ Always reply to the user in {language}.
+
+system_reminder: |
+
+ ## Operational Rules
+ - **Scope**: No unrequested refactors. Avoid full-file rewrites.
+ - **Hygiene**: Use `ContextManager`/`RemoveSkill` to evict unneeded files/skills immediately after use.
+ - **Outputs**: Tool calls trigger turns. Never include tool syntax in final user summaries.
+ - **Sandbox**: Perform all verification and temp logic in `.cecli/temp`.
+ - **Responses**: Reason out loud through the problem but be brief.
+
+ **Finishing Up**:
+ Be very detailed in your `Finished` tool summary in describing your task, findings, efforts and results.
+ Include all of your final response inside the "summary" text so maximum information is available to the user.

+description: Sub-agents enable autonomous delegation of specialized tasks to dedicated LLM sessions within the same TUI session.
+---
+
+# Sub-Agents
+
+Sub-agents allow the primary coding agent to delegate specialized sub-tasks to dedicated child agent sessions. Each sub-agent runs its own LLM loop with its own tools, conversation history, and system prompt — all within the same TUI session. This enables parallel and sequential task decomposition without leaving your workflow.
+
+Sub-agents can be used for:
+
+- **Code review** — have a dedicated reviewer analyze changes in parallel
+- **Testing** — delegate test writing to a specialist agent
+- **Research** — explore documentation or codebase structure while the primary agent works on other tasks
+- **Multi-perspective analysis** — get feedback from agents with different model backends or system prompts
+
+## Configuration
+
+### Defining Sub-Agents
+
+Sub-agents are defined using Markdown files (`.md`) with YAML front matter. The front matter specifies the agent's name and optional model override, while the body content becomes the agent's system prompt.
+
+Sub-agent definition files can be placed in any directory. You can configure which directories cecli scans using the `subagent_paths` option.
+
+### Sub-Agent File Format
+
+```markdown
+---
+name: reviewer
+model: deepseek/deepseek-v4-pro
+---
+You are a code review specialist. Your job is to analyze code changes,
+identify bugs, security issues, and style problems. Be thorough but
+constructive in your feedback. Always provide specific line numbers
+and suggestions for improvement.
+```
+
+#### Front Matter Fields
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `name` | Yes | Unique name used to reference the sub-agent in commands and the Delegate tool |
+| `model` | No | Model override for this sub-agent. If omitted, inherits the parent agent's model |
+
+#### System Prompt
+
+Any content after the closing `---` of the front matter becomes the sub-agent's system prompt. This replaces the default main system prompt for that agent. You can use this to define the sub-agent's role, behavior, and constraints.
+
+### Configuration File
+
+Add sub-agent paths to your YAML configuration file:
+
+```yaml
+# .cecli.conf.yml or ~/.cecli.conf.yml
+agent-config:
+ max_sub_agents: 3 # Maximum concurrent sub-agents (default: 3)
+ subagent_paths:
+ - ".cecli/subagents" # Default path
+ - "~/team-agents" # Custom path for shared agent definitions
+```
+
+## Usage
+
+### Available Commands
+
+| Command | Description |
+|---------|-------------|
+| `/invoke-agent ` | Invoke a sub-agent with a prompt (blocking — waits for completion) |
+| `/spawn-agent ` | Spawn a sub-agent without a prompt (non-blocking — waits for user input) |
+| `/reap-agent` | Force destroy the currently active sub-agent |
+
+> **Tip**: Both `/invoke-agent` and `/spawn-agent` support tab completion of sub-agent names.
+
+### Invoking a Sub-Agent (Blocking)
+
+The most common way to use sub-agents. The primary agent waits for the sub-agent to finish:
+
+```
+/invoke-agent reviewer Can you review the changes in editblock_func_coder.py?
+```
+
+This sends the prompt to the reviewer sub-agent, which works autonomously and returns a summary when done.
+
+### Delegating from the Primary Agent
+
+The primary agent can also delegate work using the `Delegate` tool. This enables the autonomous workflow:
+
+1. The primary agent analyzes a task
+2. It decomposes the work into sub-tasks
+3. It delegates each sub-task to the appropriate sub-agent
+4. Sub-agents work independently and return their summaries
+5. The primary agent synthesizes the results
+
+### Spawning a Sub-Agent (Non-Blocking)
+
+Creates a sub-agent that waits for you to interact with it directly:
+
+```
+/spawn-agent tester
+```
+
+Once spawned, you can switch to it and type messages directly.
+
+### Reaping a Sub-Agent
+
+Forcefully destroy the currently active sub-agent and reclaim its resources:
+
+```
+/reap-agent
+```
+
+This is useful if a sub-agent is stuck, misbehaving, or you no longer need its work.
+
+## TUI Integration
+
+### Switching Between Agents
+
+When sub-agents are active, the TUI shows agent pills in the input container's border title, displaying each agent with status icons:
+
+```
+┌─ agent: ○ primary ◆ reviewer ○ tester ─────────────────┐
+```
+
+- **Keyboard**: Use `Ctrl+Alt+Left` / `Ctrl+Alt+Right` to cycle through agents. Use `Ctrl+Alt+Up` to return to the primary agent.
+
+### Container Routing
+
+Each agent gets its own output container. When you switch agents:
+
+1. The active container is shown; all others are hidden
+2. Your input is routed to the active agent
+3. Tool output, streaming responses, and task notifications are displayed in the correct container
+4. Agent pills in the border title highlight the active agent
+
+## Lifecycle and Limits
+
+### Max Sub-Agents
+
+The `max_sub_agents` setting (default: 3) limits how many concurrent sub-agents can exist. This prevents resource exhaustion.
+
+When the limit is reached:
+
+- If any sub-agents have **finished**, the oldest finished one is automatically reaped to make room
+- If all sub-agents are still **running**, a `RuntimeError` is raised. You must wait for one to finish or use `/reap-agent` to free resources.
+
+### Cleanup
+
+- **Normal completion**: A sub-agent calls `Finished(summary="...")` which marks it as finished. Its container remains visible but its resources are eligible for lazy cleanup.
+- **Session end**: When the parent session ends, all sub-agents are automatically cleaned up.
+- **Force cleanup**: Use `/reap-agent` to immediately destroy a sub-agent and reclaim all resources.
+
+## Restrictions
+
+- **No nested sub-agents by default**: Sub-agents cannot spawn further sub-agents. The `Delegate` tool is excluded from sub-agent tool schemas by default. To enable nested delegation, set `allow_nested_delegation: true` in the agent configuration.
+- **TUI-dependent**: Sub-agent container switching and the reap command depend on the TUI. Running in headless or non-TUI modes may not support these features.
+
+## Examples
+
+### Example 1: Code Review Workflow
+
+```yaml
+# .cecli/subagents/reviewer.md
+---
+name: reviewer
+model: deepseek/deepseek-v4-pro
+description: A sub agent for reviewing edited code
+---
+You are a code review specialist. Your job is to analyze code changes,
+identify bugs, security issues, and style problems. Be thorough but
+constructive in your feedback. Always provide specific line numbers
+and suggestions for improvement.
+```
+
+```
+/invoke-agent reviewer Please review the last 5 commits in this branch
+```
+
+### Example 2: Test Writing Workflow
+
+```yaml
+# .cecli/subagents/tester.md
+---
+name: tester
+model: gemini/gemini-3-flash-preview
+description: A sub agent for running tests and interpreting results
+---
+You are a testing specialist. Your job is to write comprehensive tests
+for code changes. You should cover edge cases, error conditions, and
+happy paths. Use the project's existing testing patterns and conventions.
+```
+
+```
+/invoke-agent tester Write unit tests for the new AgentService.invoke() method
+```
+
+### Example 3: Multi-Agent Review
+
+By defining multiple sub-agents, you can get different perspectives on the same code:
+
+1. Delegate to a **reviewer** to analyze security concerns
+2. Delegate to a **tester** to identify test gaps
+3. The primary agent synthesizes both reports into an action plan
