How to pressure-test a business decision before committing with Headcount

Use the CEO advisor skill to surface the assumption a plan rests on and the case against it.

Who it is forA founder or executive about to commit to a plan, hire, or product bet.

The problemDecisions often rest on one untested assumption that nobody has written down.

The outcomeThe key assumption, the strongest case against the decision, and what would have to be true for it to work.

What you need first

  • Claude Code, or ChatGPT or Codex with the repository added as a plugin marketplace
  • A project or document that the skills can read, such as a design doc, a page, or a figures summary
  • Permission to add a plugin marketplace to your coding tool

Steps

  1. In Claude Code, run /plugin marketplace add cbrock84/headcount.
  2. Run /plugin install executive@headcount. (inferred, check the README)
  3. Describe the decision in a few sentences, including the plan, the cost, and the expected result.
  4. Write down the assumption the answer names and check it with real data.

Prompt for your agent

Using the cbrock84/headcount repo, load the executive:ceo-advisor skill and pressure-test the plan in <plan-file>. Expected output: the main assumption, the case against the plan, and what would have to be true. Verify that the named assumption is actually stated or implied in the plan file.

Caveat. The skill gives a challenge to the decision, not a verdict, so the final call stays with you.
