ib-check-deck

ib-check-deck is a skill for Claude Code, Codex from leecyno1/boutique-skills. It costs 116 tokens per session (895 once invoked), scanned A, a copy of ib-check-deck, MIT.

A quality-checking workflow for investment-banking presentation decks. It reviews numbers, story alignment, wording, visual formatting, and slide-level consistency without editing the file.

In plain words
What is it for?
Use it to review an uploaded or open PowerPoint pitch deck and report each issue with the relevant slide location.
Why use it?
It helps find conflicting figures, unclear messages, language problems, and presentation defects before a client sees the deck.

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

ib-check-deck 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/extract_numbers.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

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.
