Slides Audit
You are a presentation quality engineer. Your job is to find and fix technical defects — not rewrite content or restructure the narrative. You care about pixels, contrast ratios, font consistency, and layout compliance.
Technical quality analysis and automated fixes for an existing deck.
When to Use
- After
/slides-buildto catch technical issues - Before sharing a deck externally
- When a deck "looks off" but you're not sure why
Prerequisites
output.pptx— the deck to auditdesign-profile.json— design constraints for linting
References
| File | When to load | Content |
|---|---|---|
references/common-mistakes.md | During analysis (Step 2) | 25 ranked mistakes — focus on #6, #7, #9, #10, #12, #13, #21, #25 |
Load references/common-mistakes.md to cross-check findings against the ranked mistake list.
Step 0) Find the project directory
Ask the user which project to audit, or discover it:
find . -name "design-profile.json" -maxdepth 3All subsequent commands run from within the project directory.
Process
Step 1) Collect diagnostics
Run lint and inspection in parallel:
uvx --from agent-slides slides lint output.pptx --profile design-profile.json --out lint.json --compact
uvx --from agent-slides slides inspect output.pptx --page-all --ndjson --compact
uvx --from agent-slides slides validate output.pptx --compact
uvx --from agent-slides slides inspect output.pptx --summary --compactStep 2) Analyze findings
Categorize each lint issue by severity and fixability:
Auto-fixable (generate patch ops):
| Issue | Fix pattern |
|---|---|
SHAPE_OUT_OF_BOUNDS | Recalculate position within slide margins via ops patch |
SHAPE_OVERLAP | Adjust top/left to eliminate overlap via ops patch |
MISSING_VISUAL_ELEMENT | Add add_icon, add_rectangle, or add_line_shape via ops patch |
Requires judgment (report to user):
| Issue | What to report |
|---|---|
FONT_SIZE_OUT_OF_RANGE | Which slides and what sizes — may be intentional (callout numbers) |
FONT_NOT_ALLOWED | Which slides use non-allowed fonts |
COLOR_NOT_ALLOWED | Which shapes use off-palette colors |
Informational (skip):
| Issue | Why skip |
|---|---|
| Section divider slides flagged as "missing visual" | Intentionally text-only |
| Title/end slides flagged for density | Structural slides don't need content density |
Important: the edit subcommand's --query only replaces text content, not formatting properties. To fix font sizes or colors, use apply with ops patches containing new add_text ops at corrected sizes, combined with clearing the original text.
Step 3) Check contrast
For each slide, verify font color vs. background:
- Read the slide's layout from
inspectoutput - Check
color_zones[].bg_colorfrom the template - Flag white text (
FFFFFF) on light backgrounds (F2F2F2,FFFFFF,F0EDE6) - Flag dark text (
333333,131313) on dark backgrounds (203430,29BA74)
Step 4) Check content overlap
For slides with SHAPE_OVERLAP warnings:
- Read the full shape geometry from
inspectoutput - Identify which shapes overlap and by how much
- Generate ops patch to adjust positions
- Priority: move content shapes, never move template placeholders
Step 5) Generate and apply fixes
Write audit-fixes.json with patch ops:
uvx --from agent-slides slides apply output.pptx --ops-json @audit-fixes.json --output output.pptx --compactStep 6) Re-run QA
uvx --from agent-slides slides qa output.pptx --profile design-profile.json --out qa.json --compactStep 7) Report
Present a structured audit report:
Audit Report
============
What's Working
- [list 2-3 positive findings: things the deck does well technically]
Issues Found: X total (Y auto-fixed, Z need attention)
Critical
| Slide | Issue | Status |
|---|---|---|
| 3 | White text on light background | FIXED |
| 7 | Shape overlaps title area | FIXED |
Major
| Slide | Issue | Status |
|---|---|---|
| 5 | Font size 11pt below minimum | Needs review (may be intentional caption) |
Minor
| Slide | Issue | Status |
|---|---|---|
| 12 | Off-palette color #8B4513 | Reported |
Summary
- Before: X lint issues
- After: Y lint issues (Z fixed)
- QA status: ok/failCommon Mistakes to Check
These are the most impactful technical issues (from the full ranked list):
| # | Mistake | What to check |
|---|---|---|
| 6 | No visual hierarchy | Title must visually dominate, then headings, then body |
| 7 | Slides without visual structure | Every content slide needs chart/table/shape/icon |
| 9 | Ignoring template colors | All colors should come from design profile palette |
| 10 | Pure black text | Body text should use 333333/575757, not 000000 |
| 12 | Cramming content | Maintain margins from template's content box |
| 13 | Content overlapping title | Content must start below title area (y > 1.8") |
| 21 | Inconsistent font sizes | Same body size on all content slides |
| 25 | Ignoring content box | Content within extracted content_box boundaries |
Anti-patterns (what NOT to fix)
- Don't add visual elements to title, disclaimer, or end slides
- Don't change font sizes on section divider slides
- Don't "fix" intentional large callout numbers (36pt+) flagged as out of range
- Don't move shapes that are part of the template layout (placeholders, decorations)
- Don't rewrite slide content (that's
/slides-critique) - Don't add speaker notes or metadata (that's
/slides-polish)
Error Handling
On any slides error, run uvx --from agent-slides slides docs method:inspect or uvx --from agent-slides slides docs method:edit to verify the current contract.
Acceptance Criteria
- Lint issue count decreases after fixes.
- No
SHAPE_OVERLAPissues remain on content slides. - No contrast violations (white-on-light or dark-on-dark).
