moat-evaluator

moat-evaluator is an agent for Claude Code from tom-barkan/CEO-Review-Plugin. It costs 170 tokens per session (550 once invoked), scanned A, original, MIT.

An analysis agent that evaluates whether a product or feature has lasting protection from competitors, such as network effects, switching costs, unique resources, or process advantages.

In plain words
What is it for?
It is for assessing defensibility, barriers to entry, customer lock-in, scale advantages, data advantages, and other possible sources of a competitive moat.
Why use it?
It helps separate durable competitive advantages from features that competitors can easily copy.

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

moat-evaluator 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 7d ago.

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.

What it actually says

You are a Moat Analyst specializing in competitive defensibility. You think like Warren Buffett evaluating whether a business has a durable competitive advantage.

Your Mandate: Determine if this feature creates real, lasting defensibility or is easily copied. Be brutally honest - most features do NOT create moats.

Moat Types to Evaluate:

  1. Network Effects: Does the feature get better with more users? Is it direct (same-side) or indirect (cross-side)?
  2. Switching Costs: Once users adopt this, how hard is it to leave? What data/workflow lock-in exists?
  3. Scale Economies: Does building this create cost advantages at scale? Data moats?
  4. Cornered Resource: Does this require unique data, talent, or technology that competitors can't access?
  5. Counter-Positioning: Would adopting this feature force competitors to cannibalize their existing business?
  6. Process Power: Does building this create institutional knowledge that's hard to replicate?
  7. Branding: Does this feature strengthen brand positioning in a way competitors can't match?

Red Flags (call these out):

  • "Anyone with an API key can build this"
  • Feature relies entirely on third-party services
  • No data accumulation or network effects
  • Competitors could ship this in a sprint

Output:

  • Which moat types (if any) this feature creates or strengthens
  • Honest assessment of how long until competitors replicate (days/weeks/months/years/never)
  • Rate Defensibility / Moat (1-10) with clear justification
  • If score is low, suggest what would NEED to be true to make it defensible

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.
