Overall Process Description
Process Architecture: requirement input → content creation (1-4) → image generation creation (5) → audio and subtitle creation (6-7) → video synthesis (8: COZE API) → full-process quality inspection (9) → data feedback iteration (10)
Core Principles：
- Mandatory API Synthesis: the Video Engineer is the only one that calls the COZE platform video large model API to complete video synthesis, with no local dependency package calls
- Process Blocking Rule: if local dependency package calling behavior occurs, immediately terminate and switch to a pure COZE API synthesis process to prevent infinite loops
- API Adaptation Priority: all outputs are defined in the format required by the COZE video large model API, enabling direct upload and synthesis of "image + subtitle + audio" materials
Collaboration Rules：
- Parallel collaboration: The subtitle specialist and sound effects specialist can start in parallel after the scriptwriter outputs, improving efficiency
- Closed-loop control: All outputs must pass verification by the quality inspection agent before entering the next stage
- Iterative linkage: The optimization suggestions of the data feedback agent directly act on the underlying configuration of each agent, forming continuous iteration

- Synthesis execution: Start API synthesis, enablereal-time callback of synthesis status; if a synthesis exception occurs, immediately trigger theAPI retry mechanism(retry count ≤3 times, timeout 10 seconds), do not enter a local infinite loop; if retries fail, report a skill exception
- Finished product output: After synthesis is complete, directly obtain the finished video from the COZE API, with no local secondary editing/processing steps
-
Core Prohibitions：
- It is prohibited to call any local dependency packages (moviepy/opencv-python/mediapipe/pillow/numpy, etc.)
- Prohibit execution of any local composition scripts
- If local package invocation behavior occurs, immediately terminate the current operation and switch to the pure COZE API composition process
Collaboration Rules：
- Material pre-check synced to the quality inspection agent
- API composition parameters and finished videos synced to the quality inspection agent for verification
- If composition fails, provide feedback to the corresponding agent
- No local operations throughout the entire process; all steps are completed in the COZE API
Step 9: Quality Inspection Agent - Full-process Quality Control (New dependency package/composition exception verification)
Role Definition: Full-process quality control specialist, whose core responsibility is to conduct quality inspection of all stages of the outputs from each agent,with key verification of whether there are any local dependency package-related operations and whether materials are compatible with the COZE API, intercept defective content, drive problem rectification, and ensure unified quality of skill outputs
Trigger Conditions：
- After the storyboard artist outputs images: start "Storyboard Image Special Quality Inspection"
- After the video engineer outputs the finished product: start "Finished Video Special Quality Inspection"
- Receive outputs from each creation stage: perform random sampling inspection
Input Requirements：
- Outputs from each agent (copywriting, storyline, storyboard script, storyboard images, subtitle parameter package, sound effect material package, finished video)
- Quality standards for the corresponding stage
- COZE API adaptation requirements, rules prohibiting local dependency packages
Output Standards：
- Stage-by-stage quality inspection report: verify in the order of "copywriting→storyline→script→images→subtitles→sound effects→finished product", with newly added2 core inspection dimensions：
- Whether there are any statements/operations related to local dependency packages
- Whether all outputs are compatible with the COZE API format
- Clearly mark qualified/unqualified results, defect types, corresponding agents, and rectification suggestions
- Defect grading handling: minor defects (such as minor wording order adjustments in copywriting) are directly fed back to the corresponding agent for optimization,major defects (including mentioning/invoking local dependency packages, materials not compatible with the API, character inconsistency, subtitle obstruction) are directly intercepted from output, requiring remaking and synchronizing with the skill lead
- Quality inspection ledger: record defect data, rectification results, and qualified pass rate for each batch of outputs, forming a standardized ledger for the data feedback agent to call
Core New Dimensions of Quality Inspection：
- Process compliance: no mention or invocation of any local dependency packages (moviepy/opencv-python, etc.), with the entire process using pure online COZE API composition
- API adaptation: image, subtitle, and sound effect material formats and parameters all meet the requirements of the COZE video large model API and can be directly uploaded for composition without secondary processing
Collaboration Rules：
- Pre-inspection: mandatory quality inspection is performed on storyboard images, subtitle parameter packages, and sound effect material packages; if unqualified, the corresponding agent is rejected and must redo until standards are met
- Synchronized linkage: quality inspection results are synchronized in real time to the corresponding agent, video engineer, and data feedback agent
- Closed-loop control: track rectification results to ensure 100% resolution of defects before proceeding to the next stage
- If local dependency package invocation behavior is detected, immediately terminate composition and require the video engineer to restart the pure API composition process
Step 10: Data Feedback Agent - Data Analysis and Iterative Optimization
Role Definition: Skill Iteration Data Analyst, core responsibility is to collect, count, and analyze full-process data (with key focus onthe number of local dependency package violations, the number of API adaptation failures, and the number of subtitle adaptation issues), output iteration suggestions, optimize agent prompts and collaboration logic, and improve overall skill performance

- Iteration optimization suggestions: for high-frequency defects (such as character inconsistency, subtitle parameters not adapting to API, dependency package violations), optimize the prompt constraints of the corresponding agents; for efficiency bottlenecks, adjust the agent collaboration process
- Data accumulation: store standardized data in the skill database to form an iteration loop of "defect type-optimization plan-effect verification", adapting to subsequent skill upgrades
New Core Analysis Dimensions：
- API adaptation analysis: count the API adaptation failure rate of subtitles/sound effects/image materials, and identify root causes (such as vague prompts, incorrect format annotations)
- Process compliance analysis: count the number of local dependency package violations and the corresponding agents, and optimize the prohibited constraints in prompts
Collaboration Rules：
- Data linkage: synchronize quality inspection data and creation data in real time to ensure accurate analysis
- Iteration promotion: synchronize optimization suggestions to the skill development side, and update the underlying prompts and collaboration logic of each agent
- Effect review: track data changes after optimization, form a review report, and continuously iterate the skill
