From gtmvp-gtm-agents
Use when you need to identify a defensible set of direct, cross-shoppable competitors for a B2B brand — not a list of mega-corps that show up because they share a keyword. Provides the 4-step chain-of-thought (define profile → must-have overlap criteria → systematic search → cross-shop validation) plus the disqualifier rules that reject HubSpot/Salesforce/Adobe-class false positives when the target is sub-$50M ARR. Cited by the competitor-mapper agent and the /competitor-map slash command.

The single most common failure mode of automated competitor discovery is returning a mega-corp list. Customer of a 30-person B2B agency does not cross-shop HubSpot. This skill is the disqualifier-first method that fixes it.
Guides Next.js Cache Components and Partial Prerendering (PPR): 'use cache' directives, cacheLife(), cacheTag(), revalidateTag() for caching, invalidation, static/dynamic optimization. Auto-activates on cacheComponents: true.
Migrates code, prompts, and API calls from Claude Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5, updating model strings on Anthropic, AWS, GCP, Azure platforms.
Breaks plans, specs, or PRDs into thin vertical-slice issues on the project issue tracker using tracer bullets. Useful for converting high-level work into grabbable implementation tickets.

When invoked, run all four steps before producing any output. Skipping steps is the fastest way to fail.
Before you can do this work, gather:
If you don't have these, ask for them or pull them from the brand's site before proceeding. Do not guess.
Pin down the exact shape of the company you're searching against:
Write each of these as a single explicit statement before continuing.
From the profile, declare:
If you cannot name disqualifiers, you have not defined the profile tightly enough. Go back to Step 1.
Work outward in concentric rings:
Hard rule: Ignore companies that are 10x+ larger than the target unless the target is itself enterprise-scale. A $5M ARR boutique agency does not compete with a $5B platform — they share a keyword, not a customer.
For every candidate, ask one question and answer it explicitly:
"Would a real customer actually cross-shop these two companies?"
If the answer requires hedging ("well, theoretically..." or "if they grew 10x..."), the candidate is not a direct competitor.

example.com, no placeholders, no inferred-but-unverified URLs.rejectedCandidates is mandatory. Document at least 2-3 rejections — this is evidence the disqualifier logic ran.whitespaceGaps is the highest-leverage section. It surfaces where the brand can attack. Don't skip it.| Failure | What it looks like | Fix |
|---|---|---|
| Mega-corp drift | Salesforce, HubSpot, Adobe in the list for a sub-$50M brand | Apply Step 2 disqualifier hard |
| Keyword overlap | Two companies share "AI" but solve different problems | Use Step 4 cross-shop test |
| Half-overlap | Found companies doing one of two services in the combination | Re-check Step 1 — the combination is the requirement |
| Theoretical competition | "If they pivoted, they'd compete" | Step 4: real and current only |
| No rejections logged | Empty rejectedCandidates array | You skipped Step 2 — go back |
