Voice-of-Customer Miner
Purpose
Mine public customer voice — review sites, app stores, Reddit and practitioner forums, community
boards — for unmet needs, competitor weaknesses, and switching triggers: search plan → source sweep
→ verbatim capture → need themes → so what → next-step options. This bridges competitive
intelligence and discovery: it delivers customers' exact words without waiting on an interview cycle.
But public voice skews toward the angry and the vocal, so every theme it surfaces is a hypothesis to
validate, never a verdict — the output's last stop is always a real conversation.
Input
Works best with: the product(s) or competitor(s) to mine — yours, a rival's, or a set — and the
decision this should inform.
Also useful: a theme to focus on (onboarding, pricing, reliability) if you have one; otherwise the
sweep runs open.
Input supplied inline with the invocation — text after the skill name, a pasted context dump, or an
appended
line — counts as answers already given. Use it against the question budget;
don't re-ask.
Arriving empty-handed? That works too. The skill opens with at most 3 questions (whose voice,
what decision, theme or open sweep) and proceeds on labeled assumptions if they go unanswered.
Example invocation: Mine voice-of-customer for [Competitor A] and [Competitor B], focus on onboarding — informs whether our Q1 bet is a migration tool.
Key Concepts
- Governing protocol: honors the
contract — question budget of 3, search-plan gate, Fact/Inference/Assumption labels, Just Enough
Mode, stable schema, 4-option Final Step. Discipline: OSINT's review-and-community layer (see
intelligence-collection-disciplines
).
- Theme by need, not by feature. "Exports are broken" is a feature complaint; "I can't get my
data where my team works" is the underlying need. Theming by need is the same solution-free
discipline as JTBD and painstorming — and it's what makes themes portable into discovery.
- Verbatims are the product. Short, real, quoted customer language with URLs. Verbatims teach
persona language: the exact words customers use become interview probes and positioning copy.
Never fabricate quotes, ratings, review counts, or reviewer roles.
- Every source has a known skew. Reviewers skew negative; vendor communities skew loyal; app
stores over-represent update anger. Note the bias per source — public voice is evidence with a
known skew, not ground truth.
- Honest frequency. Recurring across sources ≠ concentrated in one thread ≠ isolated but
vivid. Say which; one articulate ranter is not a theme.
- When NOT to use: no meaningful public footprint (early-stage, niche enterprise) → run
instead; you need your users'
voice on a private area → mine your own tickets and research; statistical confidence required →
this is qualitative theming.
Application
- Credit inline context, then ask only the unanswered questions (max 3):
- Whose customer voice — yours, a competitor's, or a set?
- What decision should this inform?
- Any specific theme to focus on, or open sweep?
- Show the 3-bullet search plan — which voice sources you'll sweep, how you'll select
representative verbatims, how observation will be separated from interpretation. Continue unless
revised.
- Sweep mixed voice sources — review sites (G2, Capterra, TrustRadius), app stores, Reddit and
practitioner forums, community boards, social threads — capturing short real quotes with URLs and
noting each source's bias.
- Emit the schema below exactly.

# Voice-of-Customer Snapshot
## 1. Scope
**Products mined:** | **Decision supported:** | **Sources swept:** | **As-of date:**
## 2. Need Themes
For each of the top 3-5 themes:
### Theme: [Underlying need, solution-free, 4 to 8 words]
- **Frequency:** [recurring across sources / concentrated / isolated]
- **Verbatim:** "[short real quote]" — [source, URL]
- **Verbatim:** "[short real quote]" — [source, URL]
- **Who says it:** [role/segment, if evident — labeled]
- **Reading:** [Inference — what this suggests]
## 3. Competitor Weak Points
- **[Competitor]:** [weakness in customers' words; frequency; URL]
- [Max 5, strongest evidence only]
## 4. Switching Triggers
- [What pushes customers off a product; what pulls them; labeled, cited]
## 5. So What?
- **3** opportunity hypotheses (phrased as problems, not features)
- **2** battle-card-ready weaknesses (with evidence quality noted)
- **3** assumptions to validate in real interviews
Each bullet: label, confidence, URL where relevant.

Final Step (offer exactly 4 options)
- Generate discovery interview questions from the top theme ()
- Feed the weaknesses into a competitive battle card ()
- Build an opportunity solution tree from the top hypothesis (
opportunity-solution-tree
)
- Re-run scoped to one theme in Verbose Mode

Examples
A theme done right (fictional product, illustrative verbatims):
Theme: getting historical data out at contract end
- Frequency: recurring — 9 reviews across two sites plus a forum thread, past 6 months
- Verbatim: "export took three support tickets and still dropped custom fields" — [G2-style review, URL]
- Verbatim: "we stayed a year longer than we wanted because leaving meant losing our audit trail" — [forum thread, URL]
- Who says it: ops managers at 50-200-person firms — Inference (reviewer titles where shown)
- Reading: exit friction is functioning as involuntary retention — Inference; a rival with
effortless migration turns this from their moat into their churn event.
Notice the theme name contains no feature ("export tool") — it names the need, so discovery can
explore solutions the reviews never imagined.

FSM-software market) where frequency honesty caps a vivid theme at low confidence and each
source's bias becomes a reading instruction.

Common Pitfalls
- Feature-name theming. Clustering by the feature customers blame instead of the need underneath
hands your roadmap to the loudest UI complaint.
- Verbatim laundering. Paraphrasing a review and quoting it. If it has quote marks, it must be a
real excerpt at a real URL — this domain's do-not-invent list exists because fabricated customer
quotes are both tempting and toxic.
- Rant amplification. One vivid one-star review presented as a theme. Frequency honesty is the
discipline: recurring, concentrated, or isolated — say which.
- Skew blindness. Reading review sites as a census. The angry and the vocal are over-sampled;
the satisfied-and-silent majority never posts. Bias notes per source are mandatory.
- Skipping the validation handoff. Shipping themes straight into the roadmap. The output's
"assumptions to validate in real interviews" section is the bridge to discovery — use it.
