prd-v03-moat-definitionAssess competitor defensibility and define our own moat strategy during PRD v0.3 Commercial Model.
Prd V03 Moat Definition is an agent skill from mattgierhart/PRD-driven-context-engineering. Assess competitor defensibility and define our own moat strategy during PRD v0.3 Commercial Model. Triggers on requests to analyze competitor moats, define our defensibility, assess switching costs, identify vulnerabilities, find wedge opportunities, or when user asks "what's our moat?", "how defensible are they?", "where can we compete?", "switching costs?", "defensibility", "who to target". Consumes Competitive Landscape (v0.2) CFD- entries. Outputs CFD- entries for competitor moats and BR- entries for…
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files and assets (for example `assets/br-targeting.md`, `assets/cfd-moat-analysis.md` and `references/examples.md`).
It sits in Product & Project Management, covering PRD writing and Physical and earth sciences. The repository describes itself as: PRD-Led Context Engineering — Memory as Infrastructure. An ontology layer for product teams building products that solve real problems — with AI agents that remember. Gated PRD… The licence is MIT.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 30ed1b0. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:

No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.

From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Prd V03 Moat Definition loads about 2.3k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 145 tokens; SKILL.md has 771 words of instructions outside code blocks.
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.
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.

All CFD moat analysis entries should include:
confidence: 2-3/5 (based on public evidence + user interviews about switching friction)Example moat analysis entry:
CFD-055: Competitor Moat Analysis — Notion
Competitor: Notion
Primary Moat Type: Switching Costs (data lock-in)
Moat Strength Tier: Strong
Confidence: 3/5 (source: public-research + 2-user-interviews)
Date: 2026-02-01
Switching Cost Quantification:
- Financial: Multi-year contract, no early termination ($0 direct cost)
- Time/Effort: 20+ hours migration, team retraining
- Data Migration: Proprietary database format (complex export)
- Workflow Retraining: Unique templates, team habits
- Integration Rework: Deep Slack/GitHub dependencies
Total Switching Cost: $3K in labor + 20 hours = Material friction
Moat Verdict: Strong — switching costs >$3K + meaningful time investment
Vulnerability Signal: SMB segment with small teams; they use <20% of feature set (opportunity for simpler tool)
Targeting Decision: Avoid direct competition. Wedge in SMB with simplified, cheaper offering.
Evidence:
- CFD-042 (landscape): Reviews show enterprise love; SMB complaints focus on cost + complexity
- CFD-015 (value hypothesis): SMB would save $12,500/year with simpler tool
Next Target: "Would move to 4/5 if we interview 5+ SMB teams about exact switching cost dollars"Every moat falls into one of six types. Identify primary + secondary moats per competitor:
| Moat Type | Definition | Strong When | Weak When |
|---|---|---|---|
| Switching Costs | Friction to leave (data, workflow, contracts) | Multi-year data, deep integrations | Easy export, monthly contracts |
| Network Effects | Value increases with users | Two-sided marketplace, content platform | Single-player tool, linear value |
| Data/IP | Proprietary data or algorithms | Unique training data, patents | Commodity ML, public datasets |
| Brand/Trust | Recognition, credibility | Regulated industry, high-risk decisions | Low-stakes, undifferentiated |
| Scale/Cost | Volume economics | Infrastructure-heavy, marginal cost near zero | Labor-intensive, linear cost |
| Regulatory | Compliance barriers | Certifications required, government contracts | No compliance requirements |
For micro-SaaS: Switching costs and brand/trust matter most. Network effects and scale rarely apply.
Rate each competitor's defensibility:
| Tier | Criteria | Evidence Signals | Targeting Implication |
|---|---|---|---|
| Impenetrable | Multi-layered moat, 10+ years data lock-in | "Would take years to switch" | Avoid direct competition |
| Strong | Significant switching friction, 1-2 year contracts | High NPS + low churn despite complaints | Target underserved segments only |
| Moderate | Some friction, workarounds exist | Churn 5-10%, export options | Wedge opportunity exists |
| Weak | Easy to replace, commodity offering | Monthly plans, high churn, price shopping | Direct competition viable |
| Eroding | Former strength declining | New alternatives gaining share | Aggressive targeting |
Gate rule: Don't compete where incumbent has Impenetrable or Strong moat unless targeting segment they explicitly ignore.
Quantify ALL switching costs — the sum determines moat strength:
| Cost Type | High Impact | Low Impact | How to Assess |
|---|---|---|---|
| Financial | >6mo contract, early termination fees | Monthly billing, no penalty | Check pricing page terms |
| Time/Effort | 40+ hr migration, retraining | <4 hr setup, familiar UX | Trial the competitor |
| Data Migration | Proprietary format, no export | Standard export (CSV, API) | Test export function |
| Workflow Retraining | Unique methodology, team habits | Standard patterns | Read onboarding docs |
| Integration Rework | Deep API dependencies | Standalone tool | Map their integrations |
Calculation: Sum hours + dollars. >$5K or >40hr = material switching cost.
Use moat analysis to determine where to compete:
Moat Impenetrable/Strong → DON'T COMPETE HERE
↓ unless
Target ignored segment (SMB, specific vertical)
Moat Moderate → WEDGE STRATEGY
↓ identify
Entry point that bypasses switching friction
Moat Weak/Eroding → DIRECT COMPETITION
↓ execute
Feature + price attack on their coreA wedge exists when:
Retrieve CFD- entries from v0.2 Competitive Landscape. For each competitor, you need: pricing, complaints, feature set.
For each competitor, determine primary moat type. Use evidence from reviews, pricing structure, integration depth.
Apply tier criteria. Flag if insufficient evidence (Tier 4-5 confidence).
Complete the 5-category switching cost assessment. Quantify hours + dollars.
