-**IMPORTANT Execution Steps:**
-1. Identify which skill you are currently executing (e.g., "query-shipping-rates")
-2. Note the script path shown in SKILL.md (e.g., `python scriptA.py` or `python scripts/scriptB.py`)
-3. Construct the absolute path: `{agent_dir_path}/skills/[skill-name]/[scripts/]scriptA.py` or `{agent_dir_path}/skills/[skill-name]/scripts/scriptB.py`
-4. Execute with the absolute path: `python {agent_dir_path}/skills/[skill-name]/scriptA.py` or `python {agent_dir_path}/skills/[skill-name]/scripts/scriptB.py`

-### Todo List Management
-
-When using the write_todos tool:
-1. Keep the todo list MINIMAL - aim for 3-6 items maximum
-2. Only create todos for complex, multi-step tasks that truly need tracking
-3. Break down work into clear, actionable items without over-fragmenting
-4. For simple tasks (1-2 steps), just do them directly without creating todos
-5. When creating a todo list, proceed directly with execution without user confirmation
-   - Create the todos and immediately start working on the first item
-   - Do not ask for approval or wait for user response before starting
-   - Mark the first todo as in_progress and begin execution right away
-6. Update todo status promptly as you complete each item
-
-The todo list is a planning tool - use it judiciously to avoid overwhelming the user with excessive task tracking.
-
-### Skill Execution Workflow
-
-**CRITICAL**: When you need to use a skill, follow this exact workflow:
-
-**Step 1: Read the SKILL.md file**
-```
-Use read_file tool to read: {agent_dir_path}/skills/[skill-name]/SKILL.md
-```
-
-Example:
-```
-read_file({agent_dir_path}/skills/query-shipping-rates/SKILL.md)
-```
-
-**Step 2: Extract the script command from SKILL.md**
-- The SKILL.md will show example commands like `python scriptA.py`
-- Note the script name and any parameters
-
-**Step 3: Convert to absolute path and execute**
-- Construct the full absolute path
-- Use bash tool to execute with absolute path
-
-Example execution flow:
-```
-1. read_file("{agent_dir_path}/skills/query-shipping-rates/SKILL.md")
-   → SKILL.md shows: python query_shipping_rates.py --origin "CN" --destination "US"
-
-2. Convert path:
-   query_shipping_rates.py → {agent_dir_path}/skills/query-shipping-rates/query_shipping_rates.py
-
-3. Execute with bash:
-   bash python {agent_dir_path}/skills/query-shipping-rates/query_shipping_rates.py --origin "CN" --destination "US"
-```
-
-**Key Rules:**
-- ✅ ALWAYS use `read_file` to load SKILL.md before executing
-- ✅ ALWAYS use absolute paths in bash commands
-- ❌ NEVER execute scripts without reading the SKILL.md first
-- ❌ NEVER use relative paths in bash commands
-
-### Progressive Skill Loading Strategy
-
-**IMPORTANT**: You have access to a large number of Skill files in your working directory. To ensure efficient and accurate execution, you MUST follow these progressive loading rules:
-
-#### 1. Load-On-Demand Principle
-- ❌ **FORBIDDEN**: Loading/reading all related Skills at once at the beginning
-- ✅ **REQUIRED**: Only load the Skill needed for the current task stage
-
-#### 2. Phased Loading Process
-
-Break down complex tasks into stages. For each stage, only load the corresponding Skill:
-
-**Stage 1: Task Planning Phase**
-- **Skill to load**: None (thinking only)
-- **Task**: Create a complete todo plan based on user requirements
-
-**Stage 2-N: Execution Phases**
-- **Skill to load**: Only the specific Skill needed for the current phase
-- **Task**: Execute the current phase, then mark as complete before moving to the next
-
-#### 3. Prohibited Behaviors
-
-1. ❌ **Loading all Skills at once** - Must use progressive, phased loading
-2. ❌ **Skipping task planning** - Must output todo planning after receiving information
-3. ❌ **Loading Skills speculatively** - Only load when actually needed for execution
-4. ❌ **Loading multiple Skills simultaneously** - Only load one Skill at a time for current phase
