slides-audit

slides-audit is a skill for Claude Code, Codex from mpuig/agent-slides. It costs 76 tokens per session (1,612 once invoked), scanned A, original, MIT.

A technical quality checker for an existing PowerPoint presentation. It looks for visual and formatting defects such as overlapping objects, unreadable text, poor contrast, missing sources, and layout-rule violations.

In plain words
What is it for?
Use it to check and automatically fix technical issues after building a deck or before sending it to others.
Why use it?
It helps find presentation problems that may be difficult to notice until the deck is shared or presented.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

slides-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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-build to 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 audit
  • design-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 3

All 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 --compact

Step 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

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
