What it does

SaaS Idea Validator is an agent skill from cbrock84/headcount. Evaluates a software or startup idea against problem, market, competition, monetization, defensibility, and execution, and returns a verdict rather than encouragement. Use this when an idea needs pressure-testing before anyone builds, when deciding whether something is worth pursuing, when assessing competition or willingness to pay, or when a validated idea needs a first-customers and MVP plan. Default to scrutiny; the useful answer is usually the unwelcome one.

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 Sales & Support, covering Pricing strategy. The repository describes itself as: An agent organization structured as a company — 15+ departments, 125+ skills, each independently installable, citing the standards and regulators that settle the question. Runs… The licence is MIT.

When your agent uses it

  • Tasks that involve Pricing strategy

Example prompts

  • “Use the saas-idea-validator skill to evaluate a software or startup idea against problem, market, competition, monetization, defensibility, and…”
  • “/saas-idea-validator”

What it can do on your machine

Read from SKILL.md and the folder at commit 98d1c17. 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

SaaS Idea Validator loads about 1.1k tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 637 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~122
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.

SaaS idea validator

Most ideas fail for reasons visible before any code is written. Finding them costs an hour; not finding them costs a year.

Interrogate in this order

Problem. Who has it, how often, and what does it cost them today? An idea survives this only if you can name a specific person and what they currently do instead. "Businesses struggle with X" is not a problem statement — it is a category.

The strongest signal is a workaround: someone has built a spreadsheet, hired a contractor, or strung tools together to survive this. Paid workarounds are validated demand.

Market. Who exactly, and how many, and can you reach them? A large market you cannot address cheaply is smaller than a narrow one you can. Ask specifically: where do these people already gather, and what would it cost to reach a hundred of them this month?

Competition. Established competitors are usually good news — they prove budget exists. The dangerous answers are "nobody is doing this" (usually because it does not work or nobody pays) and "everybody is doing this" with no differentiation.

Name the actual alternative, including doing nothing and using a spreadsheet, which win far more often than competitors do.

Monetization. Who pays, how much, and out of which budget? Products die between "useful" and "someone has a line item for it." If the buyer and the user are different people, that is a different and harder business.

Defensibility. What stops a competitor copying this in a quarter? Features are not a moat. Data, switching costs, network effects, distribution, and regulatory position are.

Execution. Can this team build and sell it? Distribution is more often the binding constraint than engineering, and it is more often the one nobody has thought about.

The verdict

Give one. "It depends" is an evasion.

  • Pursue — what to validate first, and the cheapest test.
  • Pursue if — the specific condition that must hold, and how to check it.
  • Reframe — the adjacent idea that is stronger, and why.
  • Do not pursue — the reason, stated once, without softening.

Red flags

Any one of these should lower the verdict materially, and several together are usually fatal:

  • The problem is described in terms of the solution, and the founder cannot state it without mentioning their product.
  • Nobody currently pays anything to solve it, including in labor.
  • The stated advantage is "better UX" or "AI-powered" with nothing structural underneath.
  • The buyer is "everyone," or the segment widened when challenged.
  • Revenue depends on a platform whose terms could change unilaterally.
  • The founder has not spoken to ten prospective customers, and has a reason why not.

The investor lens

Whether or not you are raising, the question is clarifying: could this plausibly become large, and what would have to be true?

  • What does this look like at scale — same motion at ten times the volume, or a different business?
  • Where does growth come from once the obvious channel saturates? Most plans have exactly one channel and no answer.
  • What is the wedge and what is the expansion? A narrow entry point is a strength only if there is somewhere to go from it.
  • Why has nobody done this? Usually there is a reason. Find it before assuming you spotted something others missed.

When it survives

The first job is not building. It is finding ten people with the problem who will say what they do today and what they would pay. If ten cannot be found in a fortnight, the reachability answer above was wrong.

Then the smallest thing that delivers the value once, manually if necessary. A concierge version that works beats an automated version that might.

Never

  • Score an idea favorably because the person is invested in it.
  • Accept "there's no competition" without checking what people do instead.
  • Recommend building before anyone has said they would pay.
