Relief Pitcher AI

A Claude Code Plugin that auto-generates presentation materials — so AI can pitch in your place.

daida-ai (from Japanese daida 代打 — pinch hitter): just as a relief pitcher steps onto the mound when you can't, this plugin takes over and delivers your entire presentation for you.

Features

1. Input a talk theme and generate a structured outline in Markdown
2. Build slide decks from the outline
   • Slides are generated in PowerPoint format
   • Pre-designed slide templates (dark tech, warm casual, formal business)
   • Slides use proper layouts (not blank canvases) for consistent formatting
   • Titles and body text are set in outline-accessible placeholders
3. Write talk scripts (speaker notes) for each slide
   • Multiple speaking styles: casual, keynote, formal, humorous
4. Synthesize narration audio from the talk scripts
   • Pronunciation dictionary auto-corrects common TTS misreadings
   • TTS scripts can be exported for manual editing
5. Embed synthesized audio into the slides
6. Configure automatic slideshow playback

Supported Formats

PPTX and ODP (Open Document Presentation)

Installation

Prerequisites

• Claude Code installed
• Python 3.11+

Step 1: Add the marketplace

In Claude Code, run:

/plugin marketplace add hawkymisc/daida-ai

Step 2: Install the plugin

/plugin install daida-ai@hawkymisc-daida-ai

Step 3: Setup

On first use, run /daida-ai:relief-pitcher-ai and you will be prompted to execute the setup script. Follow Claude's instructions and approve:

bash <plugin-dir>/skills/relief-pitcher-ai/scripts/setup.sh

This creates a Python virtual environment and installs all dependencies.

Usage

Invoke in Claude Code:

/daida-ai:relief-pitcher-ai

Or use natural language:

• "Create LT slides for me"
• "Generate a presentation"
• "Make a pitch deck"

Workflow

You'll be asked interactively:

1. Theme: What the talk is about
2. Audience: Who the talk is for
3. Duration: How many minutes (default: 5)
4. Template: tech / casual / formal
5. TTS Engine: edge (default) / voicevox

The full pipeline runs automatically: Outline → Slides → Talk Script → Audio Synthesis → Audio Embedding → Slideshow Setup.

Help

Ask "help", "show usage", or "how does this work?" to see the full pipeline diagram.

Restarting from a Step

If you modify the PPTX or TTS scripts midway, you can say "restart from Step 4" to resume from that step.

Common examples:

• After editing the PPTX manually → "restart from Step 4" to regenerate audio
• After fixing pronunciation → "restart from Step 4c" to re-run audio synthesis only
• To change the template → "restart from Step 2" to regenerate slides

Fixing TTS Pronunciation

If TTS produces incorrect readings, you can fix them in two ways:

• Pronunciation dictionary: Define substitution rules in skills/relief-pitcher-ai/assets/pronunciation_dict.tsv (applied automatically at export time)
• Manual editing: Export the TTS script and edit it directly in a text editor

Templates

Template	Style	Font
tech	Dark theme, cyan accents	Noto Sans CJK JP
casual	Warm tones, rounded design	Noto Sans CJK JP
formal	White base, business-oriented	Noto Serif CJK JP / Noto Sans CJK JP

Note: Templates are currently optimized for Japanese content. For other languages, system fonts will be used as fallback.

TTS Engines

Engine	Description	Notes
edge-tts	Microsoft Edge TTS. No installation required. Supports multiple languages.	Default
VOICEVOX	Character voices (e.g., Zundamon). Japanese-language TTS engine.	Requires VOICEVOX Engine running

Validation

The following validations are automatically applied to the slide specification JSON (generated by LLM):

• Slide count (1–20 slides)
• Layout-field consistency (e.g., two_content requires left/right)
• Text length limits (title: 100 chars, body item: 200 chars, etc.)
• Audio file format (MP3/WAV) and size (max 50 MB)
• Estimated speaking duration check

Notes

Playback in LibreOffice Impress

Auto-advance (automatically moving to the next slide after audio finishes) only works in PowerPoint (Windows / macOS).

LibreOffice Impress does not support auto-advance. This is a known limitation where LibreOffice does not correctly process PPTX timing settings (advTm) — see Bug 101527.

When using LibreOffice Impress:

• Advance slides manually (click or arrow keys)
• Or set auto-advance times manually via the "Slide Transition" panel in LibreOffice
