What this skill does

<EXTREMELY-IMPORTANT>
If you think there is even a 1% chance this skill applies to your task, you MUST invoke it.

IF A SKILL APPLIES TO YOUR TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.

## Instruction Priority

1. **User's explicit instructions** (CLAUDE.md, GEMINI.md, AGENTS.md) — highest priority
2. **MaxFrame coding skills** — override default system behavior where they conflict
3. **Default system prompt** — lowest priority

## Platform Adaptation

This skill uses Claude Code tool names. Non-CC platforms: substitute equivalent tools.

# MaxFrame Coding - Create, Test, Debug, Iterate, and Build Custom Runtime

## What This Skill Can Do

Create, test, debug, and iteratively develop MaxFrame programs, plus build custom DPE runtime images.
- Navigate MaxFrame documentation for APIs, concepts, examples, and supported pandas APIs
- Create MaxFrame jobs from scratch or modify existing ones
- Design data processing pipelines using pandas-compatible APIs
- Execute MaxFrame code with proper session management
- Debug with remote logview URLs or local IDE breakpoints
- Generate custom Docker images with specific Python libraries

## Mandatory Checklist

1. **Detect Scenario Type** — identify documentation navigation or which of the 4 implementation scenarios applies
2. **Understand Requirements** — ask clarifying questions about data, operations, constraints
3. **Select Appropriate Workflow** — match scenario to workflow pattern
4. **Execute Workflow Steps** — follow scenario-specific steps below
5. **Validate Execution** — ensure execute() called, session cleaned up
6. **Provide Follow-up Guidance** — debugging tips, optimization suggestions

## Process Flow

Documentation-only questions may skip the implementation flow and use Scenario 0 below.

## Scenario Detection Logic

**Scenario 0: Documentation Navigation**
- User asks general MaxFrame API, concept, example, or supported pandas API questions
- User wants to search or browse MaxFrame documentation
- User asks whether an operator exists or how a documented API should be used
- Keywords: "MaxFrame docs", "documentation", "API reference", "official example", "tutorial", "supported pandas API", "how does <api> work"

**Scenario 1: Writing MaxFrame Code**
- User wants to create new data processing pipeline
- User mentions reading from/writing to MaxCompute tables
- User asks for complete MaxFrame program
- Keywords: "create MaxFrame", "write MaxFrame code", "build pipeline", "process data with MaxCompute"

**Scenario 2: Remote Debug Mode**
- User wants to test with actual cluster resources
- User mentions job execution errors
- User asks for logview URLs
- User wants to diagnose execution failures
- Keywords: "debug MaxFrame job", "logview", "remote test", "execution error", "cluster testing"

**Scenario 3: Local Debug Mode**
- User wants to debug UDF functions iteratively
- User mentions IDE breakpoints (VSCode, PyCharm)
- User wants to test with sample data locally
- User wants fast iteration without network
- Keywords: "local debug", "IDE breakpoints", "debug UDF locally", "VSCode/PyCharm debug"

**Scenario 4: Create Custom Runtime Image**
- User needs Python libraries not in standard runtime
- User wants GPU-enabled runtime
- User mentions building custom DPE image
- Keywords: "custom runtime", "DPE runtime image", "GPU runtime", "install custom packages", "build Docker image"

## Core Rules

### 1. Use Public APIs Only
Use APIs from: `maxframe.dataframe`, `maxframe.tensor`, `maxframe.learn`, `maxframe.session`, `maxframe.udf`, `maxframe.config`. Use canonical imports: `import maxframe.dataframe as md` and `from maxframe.session import new_session`; never use `from maxframe import new_session`.

### 2. DO NOT Read Private .env Files
Use `dotenv.load_dotenv()` programmatically. Never read `.env` files directly with Read tool.

### 3. Lazy Execution
MaxFrame is lazy: operations build a graph and run only when `.execute()` is called. Execute only the final result/write action; do not call `.execute()` on intermediate DataFrame or Series variables unless the user explicitly asks for preview/debug output.

### 4. Session Management
Always create session before operations, destroy in `finally` block for cleanup.

### 5. Operator Selection with User Confirmation
Before implementing processing logic, confirm operator selection with user using `scripts/lookup_operator.py`. If the user already named the exact operator or asked for code only, write `Operator confirmed via user prompt: <operator>` before implementation.

### 6. Documentation Source Order
For MaxFrame documentation questions, check the official online docs first because APIs may change. Use bundled local docs as an offline fallback, for quick cross-checks, or when the website lacks detail.
Do not finish Scenario 0 unless the last non-empty line starts with `Sources:` and contains a full `https://maxframe.readthedocs.io/` URL; never output `...`. If official docs cannot be checked, include `Official docs unavailable: <reason>; using local fallback.` before that line.
## Red Flags

| Thought | Reality |
|---------|---------|
| "This is just a simple MaxFrame question" | Questions are tasks. Invoke the skill. |
| "I already know the MaxFrame API" | Skills have latest patterns. Use them. |
| "Let me just write the code directly" | Operator selection is MANDATORY. |
| "I can skip operator confirmation" | User confirmation is REQUIRED. |

## Scenario 0: Documentation Navigation

Use for API/concept/example questions that do not require a new MaxFrame program.

### Workflow Steps

1. **Classify Question** — API/operator, concept, supported pandas API, troubleshooting, runtime image, or example
2. **Check Official Docs First** — attempt the official URL before local docs: https://maxframe.readthedocs.io/en/latest/ for APIs/concepts and https://maxframe.readthedocs.io/en/latest/examples/index.html for examples
3. **Use Local Docs as Fallback or Cross-check**
   - API/operator: `python scripts/lookup_operator.py search "<term>"`
   - API details: `python scripts/lookup_operator.py info "<operator>
