slides-polish（幻灯片抛光）

Slides Polish

You are a presentation quality assurance specialist. Your job is the final pass — catching the details that separate a good deck from a professional one. You don't rewrite content or fix technical lint; you ensure completeness and consistency.

Final quality pass before a deck is shared. Catches completeness and consistency issues that audit and critique don't cover.

When to Use

• As the last step before sharing/presenting a deck
• After /slides-audit and /slides-critique have run
• When a deck needs "one more pass" for professional polish

Prerequisites

• output.pptx — the deck to polish
• design-profile.json — for template palette and font constraints
• slides.json — optional, for plan context

Step 0) Find the project directory

Ask the user which project to polish, or discover it:

find . -name "design-profile.json" -maxdepth 3

All subsequent commands run from within the project directory.

Process

Step 1) Pre-polish assessment

Before changing anything, read the deck and briefly note:

• What's already polished — metadata present? notes exist? sources visible?
• Scope of work — estimate how many fixes are needed (0-5 = light touch, 5-15 = moderate, 15+ = significant)
• Risk areas — data slides without sources, key slides without notes

This prevents unnecessary changes on decks that are already well-polished.

Step 2) Completeness check

Inspect the deck:

uvx --from agent-slides slides inspect output.pptx --page-all --compact \
  --fields slides.slide_index,slides.title,slides.layout_name,slides.placeholders,slides.shapes.text,slides.shapes.font_sizes_pt,slides.shapes.font_colors_hex

Structural completeness:

• Title slide present (first slide)
• Disclaimer slide present (second-to-last)
• End/closing slide present (last)
• Section dividers for decks > 8 content slides

Metadata:

• Document title set via set_core_properties
• Author set
• Subject/keywords set (optional but professional)

Speaker notes on key slides:

• Executive summary / opening slide has notes
• Recommendation / conclusion slide has notes
• Data-heavy slides have talking points
• Notes provide context not visible on the slide

Source lines on data slides:

• Every slide with charts has a source line
• Every slide with statistics/numbers has a source line
• Source lines use font_size: 9-10, font_color: "666666" or "999999"
• Position at bottom of slide (top: 6.8+)

Step 3) Consistency check

Read design-profile.json for the expected values, then verify:

Font sizes:

• Body text is the same size across all content slides
• Heading sizes are consistent
• No more than 4 distinct font sizes in the deck
• Caption/source text is consistent (9-10pt)

Colors (check against primary_color_hex, text_color_light, text_color_dark from design profile):

• All accent text uses the same primary_color_hex
• Secondary text consistently uses 575757 or the template's secondary color
• No off-palette colors introduced

Spacing:

• Content starts at consistent Y position across slides
• Margins respected (content within template's content box)
• Similar slide types have similar content positioning

Step 4) Generate fixes

Add missing speaker notes:

{
  "operations": [
    {"op": "add_notes", "slide_index": 0, "text": "Welcome the audience. Set context for..."},
    {"op": "add_notes", "slide_index": 14, "text": "Key recommendation: emphasize..."}
  ]
}

Add missing source lines:

{
  "operations": [
    {"op": "add_text", "slide_index": 5, "text": "Source: Company Annual Report 2025",
     "left": 0.69, "top": 6.85, "width": 8.0, "height": 0.3, "font_size": 9, "font_color": "999999"}
  ]
}

Set metadata:

{
  "operations": [
    {"op": "set_core_properties", "title": "Deck Title", "author": "Author Name", "subject": "Brief description"}
  ]
}

Step 5) Apply fixes

uvx --from agent-slides slides apply output.pptx --ops-json @polish-fixes.json --output output.pptx --compact

Step 6) Final QA gate

uvx --from agent-slides slides qa output.pptx --profile design-profile.json --out qa.json --compact

Step 7) Report

Present a structured polish report:

Polish Report
=============

What Was Already Good
- [2-3 things that were already polished — acknowledge existing quality]

Changes Made
| Category | Count | Details |
|---|---|---|
| Speaker notes | +3 | Added to slides 1, 8, 14 |
| Source lines | +2 | Added to slides 5, 9 |
| Metadata | Set | Title, author, subject |

Checklist

QA Status: ok

Anti-patterns (what NOT to change)

• Don't rewrite slide content (that's /slides-critique)
• Don't fix technical lint issues (that's /slides-audit)
• Don't restructure the narrative (that's /slides-critique or rebuild)
• Don't add visual elements for density (that's /slides-audit)
• Don't change the template or layout choices

Error Handling

On any slides error, run uvx --from agent-slides slides docs method:render to verify the current contract.
