AC slide-to-video-converter

End-to-end pipeline for converting PPT/PPTX/PDF slides with speaker notes into narrated MP4 videos. Defaults to Edge TTS (Microsoft free online API) for universal compatibility. Supports three TTS modes: Edge TTS (default), Qwen3-TTS (local GPU acceleration), and HTTP service. Features audio validation, auto-synced subtitles, batch processing, and PPTX support via LibreOffice conversion. Input: PPT/PPTX/PDF file + JSON subtitles. Output: High-quality MP4 video with narration and subtitles. Use when users want to: (1) Automate video creation from presentations, (2) Generate training/lecture videos with TTS, (3) Batch produce slide-based content, (4) Create videos with consistent quality control, (5) Convert PPTX files to video.

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Process rating: all ten parameters 52/100

    • 0Result and completion. Does not say what the result is
    • 0Inputs and preconditions. Does not say what the process needs to start
    • 0Progress reporting. Says nothing while it works
    • 30Running it twice. 1 mutating operations with no state check
    • 50When it triggers. No condition that starts the skill
    • 50Failures and branches. 0 branches, has a failure section
    • 60Tools and files. Uses tools (bash, python) that frontmatter does not declare
    • 100Steps. 30 steps
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 1858 tokens

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

    Quality signals

    • +5Description has no quoted example phrases that should trigger the skill
    • +4Description does not say when NOT to use the skill (false activations)
    • +3Output format is not stated: the model decides each time
    • -37 of 9 scripts are never mentioned in SKILL.md
    • +1No license
    • +2Single-language instructions
    • +3Description length 736: enough signal without eating the budget

    Quality base 70; lint remarks subtract, signals add up to 100. Result: 85.

    External checks

    ClawHub: suspicious
    This appears to be a real slide-to-video tool, but its optional TTS server is too open and could expose or overwrite local files if reachable by others.
