What it does

Mckinsey Critic is an agent skill from sruthir28/enterprise-ai-skills. Reviews decks, documents, and strategies like a McKinsey engagement manager. Grades each section, flags structural problems, and gives the top 3 fixes. Use after building a deck, writing a strategy doc, or outlining a recommendation — before it goes to stakeholders.

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Open-source AI skills for enterprise professionals. McKinsey consulting frameworks, PM workflows, and practical tools. Currently for Claude, expanding to other LLMs. The licence is MIT.

Example prompts

  • “Use the mckinsey-critic skill to review decks, documents, and strategies like a McKinsey engagement manager”
  • “/mckinsey-critic”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Grade the overall work (Green / Yellow / Red)
  2. Review each section or slide with a status and specific issue
  3. Identify the top 3 fixes — ranked by impact, with clear instructions
  4. Call out one thing that works — so you know what to protect

What it can do on your machine

Read from SKILL.md and the folder at commit ae8fe60. 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

Mckinsey Critic loads about 983 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 440 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~983

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
Reviews decks, documents, and strategies like a McKinsey engagement manager. Grades each section, flags structural problems, and gives the top 3 fixes. Use after building a deck, writing a strategy doc, or outlining a recommendation — before it goes to stakeholders.

McKinsey Critic

Reviews your work the way a McKinsey engagement manager would at 2am before a client presentation. Catches structural problems, weak arguments, missing data, and logical gaps — then tells you exactly what to fix.

How It Works

Give the critic any deck outline, strategy document, memo, or recommendation. It will:

  1. Grade the overall work (Green / Yellow / Red)
  2. Review each section or slide with a status and specific issue
  3. Identify the top 3 fixes — ranked by impact, with clear instructions
  4. Call out one thing that works — so you know what to protect

Grading Scale

GradeMeaning
GreenReady for stakeholders. Minor polish only.
YellowFixable overnight, but do not send as-is. Structural issues that undermine credibility.
RedNeeds rework. Core argument or structure is broken.

What the Critic Checks

Structure
  • Does the narrative flow logically? (Problem → Context → Analysis → Solution)
  • Are section breaks in the right place?
  • Is there a clear beginning, middle, and end?
Rigor
  • Is every claim backed by data or a source?
  • Are numbers specific, not vague ("grew significantly" → "grew 25% YoY")?
  • Are comparisons fair and complete?
  • Is there a financial frame where one is needed?
So-What
  • Does each section have a clear takeaway?
  • Can someone read just the titles/headers and understand the full argument?
  • Is the recommendation actionable and time-bound?
Completeness
  • Are there comparison frameworks where options are presented? (not just a list)
  • Are competitors named, not described generically?
  • Are next steps specific with owners and timelines?

Common Problems the Critic Catches

  • Topic titles instead of claim titles — "Market Overview" vs "Global coffee market will reach $373B by 2030"
  • Lists where frameworks belong — three options as bullets vs a comparison table with dimensions
  • Missing financial frame — recommendations without revenue/cost/investment sizing
  • Unsourced statistics — numbers without citations destroy credibility
  • Structural errors — solution content in the problem section, complication slides after resolution
  • Vague recommendations — "allocate resources" instead of "$15-25M Phase 1 investment over 12 months"
  • No "so what" — data presented without interpretation or implication

When to Use

  • After building a deck (with Storyline Builder or any other method)
  • Before sending a strategy document to leadership
  • When reviewing a team member's work
  • After writing a memo or recommendation
  • Any time work needs to survive a senior audience

Tips

  • Run the critic BEFORE you polish formatting. Fix structure first, then make it pretty.
  • The top 3 fixes are ranked by impact. If you only have time for one fix, do Fix 1.
  • Yellow is the most common grade. That's expected — it means the thinking is right but the execution needs tightening.
  • Pair with the Storyline Builder. Build the narrative first, then let the critic review it.
