Premiere Agent Closed Loop

Overview

This skill captures the repo-local workflow for turning premiere-mcp into a closed-loop editing agent instead of a loose collection of tools.

When to Use

• Adding or changing agent orchestration behavior
• Introducing task scenarios such as viral_style or reference_video
• Adding post-write verification or critic-style review gates
• Standardizing tool/runtime errors for programmatic recovery

Required Workflow

1. Classify the request into an explicit scenario first.
2. Produce a structured plan with prerequisites, success criteria, and per-step failure behavior.
3. Enforce the research gate before any style-driven assembly work.
4. Verify important write operations with read-back comparison.
5. Run an independent critic before reporting success.
6. Emit a structured failure report when the loop aborts.

Guardrails

• Do not allow build_timeline_from_xml on the agent path while it is marked disabled.
• Do not let viral_style or reference_video skip research and go straight to assembly.
• Do not treat ok:true or success:true as completion without verification and critic results.
• Do not leave failures as free-form strings only; keep error_code and retryable available for runtime decisions.

Common Mistakes

• Folding planning, execution, validation, and review into one opaque step
• Using existence-only checks where the task needs value comparison
• Letting the execution layer self-certify success without a critic pass
• Forgetting to preserve fallback guidance for disabled tools
