From the author

Investment banking presentation quality checker. Reviews a pitch deck or client-ready presentation for (1) number consistency across slides, (2) data-narrative alignment, (3) language polish against IB standards, (4) visual and formatting QC. Use whenever the user asks to review, check, QC, proof, or do a final pass on a deck, pitch, or client materials — including requests like "check my numbers", "reconcile figures across slides", "is this client-ready", or "what am I missing before I send this out".

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The ib-check-deck skill provides a structured framework for auditing professional pitch decks. It performs a multi-dimensional review focusing on numerical consistency, data-narrative alignment, professional language standards, and visual formatting. By extracting content from slides and applying specific validation logic, it helps ensure that high-stakes financial presentations are accurate, polished, and ready for client delivery.

What it does

  • Identifies numerical inconsistencies across multiple slides.
  • Validates that narrative claims are supported by the provided data.
  • Polishes language to meet professional investment banking standards.
  • Checks for visual and formatting errors such as missing citations or inconsistent styles.
  • Categorizes findings by severity to prioritize critical fixes.
  • Generates a structured report for final review.

When to use it

  • Before sending a pitch deck or client-ready presentation.
  • When you need to reconcile figures across a large slide deck.
  • To ensure your presentation language is formal and free of casual phrasing.
  • When performing a final quality control pass on financial materials.

Advantages

  • Reduces human error in complex financial data reporting.
  • Ensures consistent terminology and tone throughout the document.
  • Provides clear, actionable feedback categorized by impact.
  • Standardizes the review process for client-facing materials.

Usage examples

“Can you check my numbers and reconcile figures across these slides?”
The agent will extract numerical data from the deck, flag any conflicting values across slides, and report them in the specified format.
“Is this pitch deck client-ready?”
The agent will perform a full audit covering number consistency, narrative alignment, language polish, and formatting, providing a summary report of issues.
“What am I missing before I send this out?”
The agent will conduct a comprehensive review of the deck and highlight any critical, important, or minor issues that require attention.

Documentation by Anthropic

IB Deck Checker

Perform comprehensive QC on the presentation across four dimensions. Read every slide, then report findings.

Environment check

This skill works in both the PowerPoint add-in and chat. Identify which you're in before starting:

  • Add-in — read from the live open deck.

  • Chat — read from the uploaded .pptx file.

This is read-and-report only — no edits — so the workflow is identical in both.

Workflow

Read the deck

Pull text from every slide, keeping track of which slide each line came from. You'll need slide-level attribution for every finding ("$500M appears on slides 3 and 8, but slide 15 shows $485M"). A deck with 30 slides is too much to hold in working memory reliably — write the extracted text to a file so the number-checking script can process it.

The script expects markdown-ish input with slide markers. Format as:

## Slide 1
[slide 1 text content]

## Slide 2
[slide 2 text content]
1. Number consistency

Run the extraction script on what you collected:

python scripts/extract_numbers.py /tmp/deck_content.md --check

It normalizes units ($500M vs $500MM vs $500,000,000 → same number), categorizes values (revenue, EBITDA, multiples, margins), and flags when the same metric category shows conflicting values on different slides. This is the part most likely to catch something a human missed on the fifth read-through.

Beyond what the script flags, verify:

  • Calculations are correct (totals sum, percentages add up, growth rates match the endpoints)

  • Unit style is consistent — the deck should pick one of $M or $MM and stick with it

  • Time periods are aligned — FY vs LTM vs quarterly, explicitly labeled

2. Data-narrative alignment

Map claims to the data that's supposed to support them. This is where decks go wrong quietly — someone edits the chart on slide 7 and forgets the narrative on slide 4.

  • Trend statements ("declining margins") → does the chart actually go that direction?

  • Market position claims ("#1 player") → revenue and share data support it?

  • Plausibility — "#1 in a $100B market" with $200M revenue is 0.2% share; that's not #1

3. Language polish

IB decks have a register. Scan for anything that breaks it: casual phrasing ("pretty good", "a lot of"), contractions, exclamation points, vague quantifiers without numbers, inconsistent terminology for the same concept.

See references/ib-terminology.md for replacement patterns.

4. Visual and formatting QC

Run standard visual verification checks on each slide. You're looking for: missing chart source citations, missing axis labels, typography inconsistencies, number formatting drift (1,000 vs 1K within the same deck), date format drift, footnote and disclaimer gaps.

Visual verification catches overlaps, overflow, and contrast issues that don't show up in text extraction. Don't skip it — a chart with no source citation looks the same as a properly sourced one in the text dump.

Output

Use references/report-format.md as the structure. Categorize by severity:

  • Critical — number mismatches, factual errors, data contradicting narrative. These block client delivery.

  • Important — language, missing sources, terminology drift. Should fix.

  • Minor — font sizes, spacing, date formats. Polish.

Lead with criticals. If there aren't any, say so explicitly — "no number inconsistencies found" is a finding, not an absence of one.

      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,

      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
