A structured task processing framework for Claude Code. MCE transforms any request into executable, governed workflows.
Master Control Expert (MCE) is a task classification and execution framework that helps Claude Code efficiently handle various types of tasks. Through standardized processes and prompt templates, MCE ensures every task receives systematic, high-quality processing.
Receive Task → Intake → Classify → Plan → Deliver → Evolve
- Intake - Collect necessary information using the universal checklist
- Classify - Categorize the task into A-H categories
- Control - Output control summary and definition of done
- Execute - Apply corresponding prompt templates and produce concrete deliverables
- Evolve - Self-assess and propose category additions or prompt improvements
| Category | Name | Use Cases |
|---|---|---|
| A | Logic & Argumentation | Argument audits, validity checks, counterexamples, "cold-water reviews" |
| B | Math / Theory Explanation | Tiered explanations, concept maps, learning routes, book lists |
| C | Engineering Delivery | Systems, refactors, specs, incidents, deployment |
| D | Product / Mechanism Design | Governance, rules, incentives, anti-abuse, sustainability |
| E | Writing & Publishing | Outlines, rewrites, de-duplication, editorial guidance |
| F | Policy / Legal / Compliance | Legal reasoning, compliance checklists, policy analysis |
| G | Research Curation / Study Guide | Knowledge maps, reading guides, tagging systems, bibliographies |
| H | Events & Project Management | Conferences, forums, awards, competitions, dinners |

When activated in Claude Code, the system automatically follows the MCE framework to process tasks:
/master-control-expert
- First consult
playbook/intake_checklist.mdfor intake - Based on task type, consult corresponding template in
playbook/prompt_catalog.md - Use
playbook/control_plan.mdto plan execution - Record important decisions in
playbook/decision_log.md
- Direct and Operational: Provide clear checklists, tables, and numbered steps
- No Stalling: Deliver immediately, don't promise future work
- Explicit Assumptions: When information is insufficient, make reasonable assumptions and label them
- Track Decisions: Explicitly record decisions, maintain a decision log
- Concrete Deliverables: Files, content blocks, executable steps
- Self-Evolving: Continuously assess category coverage and prompt effectiveness, proactively improve
MCE has self-evolution capabilities and can automatically optimize based on usage:
When a task doesn't fit any A-H category, MCE will:
- Assess whether a new category is needed
- Present a new category proposal to the user (name, definition, prompt skeleton)
- Upon user confirmation, automatically update relevant files
- Record in
evolution_protocol.md
Triggers:
- Task differs from A-H by > 70%
- 3 consecutive tasks fall into Other with related themes
- User explicitly requests a new category
When a category's prompt effectiveness is suboptimal, MCE will:
- Diagnose the issue (missing/redundant/misordered)
- Present improvement proposal to user (before/after comparison)
- Upon user confirmation, update
prompt_catalog.md - Increment version number and record improvement log
Triggers:
- User feedback indicates poor effectiveness
- Prompt skeleton found to miss key items
- User repeatedly overrides default sections
- Same category requires major adjustments 2+ times
See playbook/evolution_protocol.md for details.
For each task, MCE produces:
- Control Summary: Objective, deliverables, constraints, assumptions, risks, definition of done
- Execution Plan: Milestones, resources, steps
- Concrete Deliverables: Actual files/content blocks
- Decision Log Entries: Record key decisions
