What it does

Deck Autopsy is an agent skill from mohitagw15856/pm-claude-skills. Autopsy a slide deck from photos or screenshots of its slides — the narrative arc, the numbers, and what each slide is hiding. Use when given slide images (a competitor's pitch, a conference talk, your own deck before a big meeting) and asked what the deck argues, whether it holds up, or how to counter or improve it. Produces a slide-by-slide read, the reconstructed argument chain, weak links, and the questions the deck is engineered to avoid. Requires image input.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering Slides and decks. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Given slide images (a competitors pitch
  • A conference talk
  • Your own deck before a big meeting) and asked what the deck argues
  • Whether it holds up

Example prompts

  • “/deck-autopsy”

  1. Read each slide twice. Once for the claim (usually the headline), once for the support (the chart, the numbers, the logos). A slide whose…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Deck Autopsy loads about 1.1k tokens when it runs. Until then it costs about 121 tokens; SKILL.md has 593 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Autopsy a slide deck from photos or screenshots of its slides — the narrative arc, the numbers, and what each slide is hiding. Use when given slide images (a competitor's pitch, a conference talk, your own deck before a big meeting) and asked what the deck argues, whether it holds up, or how to counter or improve it. Produces a slide-by-slide read, the reconstructed argument chain, weak links, and the questions the deck is engineered to avoid. Requires image input.

Deck Autopsy Skill

A deck is an argument wearing design. This skill reads slide images the way a sceptical partner does — reconstructing the claim chain, checking the numbers against each other across slides, and naming the questions the deck is built to keep the room from asking.

What This Skill Produces

  • A slide-by-slide read: each slide's claim, its evidence, and what the design emphasises or buries
  • The reconstructed argument chain — the deck's whole case as explicit premises → conclusion, with the weak links marked
  • A cross-slide consistency check on the numbers
  • The avoided questions — what a hostile reader asks that the deck never answers, and (if it's your deck) how to fix that before they do

Required Inputs

  • The slide images, in order if possible. If none attached, ask — this skill autopsies real slides, not deck ideas.
  • Whose deck and why (ask if missing): analysing a competitor/pitch, or hardening your own before the meeting — the output's stance flips accordingly.

Autopsy Method

  1. Read each slide twice. Once for the claim (usually the headline), once for the support (the chart, the numbers, the logos). A slide whose headline isn't proven by its own body gets flagged on the spot.
  2. Read the design as rhetoric. Truncated y-axes, cherry-picked date ranges, percentages without denominators, log scales unannounced, "representative" logos — chart crimes are claims about weakness. Note them per slide.
  3. Reconstruct the chain. The deck's argument as numbered premises leading to its ask. Every deck has one; most hide a step. The hidden step is the weakest link.
  4. Cross-examine the numbers. Do the figures agree across slides (TAM vs revenue math, growth rate vs the chart, headcount vs burn)? Cross-slide inconsistency is the highest-value finding an autopsy produces.
  5. List the avoided questions. Given the claims made, what would a sceptic ask next that no slide answers? Absence is evidence of the sore spot.
  6. Anchor everything. Every finding cites its slide number. Unreadable content is flagged, never guessed.

Deck autopsy: [deck] — [n] slides examined

The deck's argument, reconstructed:

  1. [premise — slide #]
  2. [premise — slide #] ∴ [the ask/conclusion — slide #] Weakest link: [which step, why]

Slide-by-slide: [#n] — Claims: [headline]. Support: [what's actually shown]. Design notes: [emphasis/burial/chart crimes]. Verdict: holds / overreaches / unproven.

Numbers cross-check:

FigureSlide(s)Consistent?Note

Questions this deck is built to avoid:

  1. [question] — [what triggers it, which slide dances around it]

[If it's your deck] Hardening list: [the 3-5 fixes, in order of how likely each hole is to be found in the room]

Quality Checks

  • Every finding cites a slide number; illegible content is flagged, not guessed
  • Each slide's headline was checked against its own body, not just read
  • Chart integrity was examined (axes, ranges, denominators), not just chart content
  • Numbers were cross-checked between slides, not only within them
  • The avoided-questions list follows from the deck's own claims, not generic due-diligence boilerplate

Anti-Patterns

  • Do not autopsy from a deck's reputation or your memory of the company — only from the slides provided
  • Do not proceed without slide images — for text notes about a future deck, use board-deck-narrative or investor-pitch-deck instead
  • Do not treat beautiful design as evidence of a strong argument — the correlation runs the other way often enough
  • Do not list ten nitpicks and skip the structural weakness — one broken chain link outweighs every font choice
  • Do not soften findings on your own deck — the room won't

Example Trigger Phrases

  • "What is this deck really arguing?"
  • "Pick apart this competitor's pitch deck."
  • "Here are photos of their slides: what are they hiding?"
  • "Does my deck hold up before the big meeting?"
