Market Opportunity Analysis

Overview

This public intake copy packages

plugins/antigravity-awesome-skills-claude/skills/startup-business-analyst-market-opportunity

https://github.com/sickn33/antigravity-awesome-skills

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses

metadata.json

ORIGIN.md

Market Opportunity Analysis Generate a comprehensive market opportunity analysis for a startup, including Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM) calculations using both bottom-up and top-down methodologies.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Instructions for Claude, Tips for Best Results, Notes, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• Working on market opportunity analysis tasks or workflows
• Needing guidance, best practices, or checklists for market opportunity analysis
• The task is unrelated to market opportunity analysis
• You need a different domain or tool outside this scope
• Use when the request clearly matches the imported source intent: 'Generate comprehensive market opportunity analysis with TAM/SAM/SOM.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Clarify goals, constraints, and required inputs.
2. Apply relevant best practices and validate outcomes.
3. Provide actionable steps and verification.
4. If detailed examples are required, open resources/implementation-playbook.md.
5. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
6. Read the overview and provenance files before loading any copied upstream support files.
7. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.

Imported: Instructions for Claude

When this command is invoked, follow these steps:

Step 1: Gather Context

Ask the user for essential information:

• Product/Service Description: What problem is being solved?
• Target Customers: Who is the ideal customer? (industry, size, geography)
• Business Model: How does pricing work? (subscription, transaction, etc.)
• Stage: What stage is the company? (pre-launch, seed, Series A)
• Geography: Initial target market (US, North America, Global)

Step 2: Activate market-sizing-analysis Skill

The market-sizing-analysis skill provides comprehensive methodologies. Reference it for:

• Bottom-up calculation frameworks
• Top-down validation approaches
• Industry-specific templates
• Data source recommendations

Step 3: Conduct Bottom-Up Analysis

For B2B/SaaS:

1. Define customer segments (company size, industry, use case)
2. Estimate number of companies in each segment
3. Determine average contract value (ACV) per segment
4. Calculate TAM: Σ (Segment Size × ACV)

For Consumer/Marketplace:

1. Define target user demographics
2. Estimate total addressable users
3. Determine average revenue per user (ARPU)
4. Calculate TAM: Total Users × ARPU × Frequency

For Transactions/E-commerce:

1. Estimate total transaction volume (GMV)
2. Determine take rate or margin
3. Calculate TAM: Total GMV × Take Rate

Step 4: Gather Market Data

Use available tools to research:

• WebSearch: Find industry reports, market size estimates, public company data
• Cite all sources with URLs and publication dates
• Document assumptions clearly

Recommended data sources (from skill):

• Government data (Census, BLS)
• Industry reports (Gartner, Forrester, Statista)
• Public company filings (10-K reports)
• Trade associations
• Academic research

Step 5: Top-Down Validation

Validate bottom-up calculation:

1. Find total market category size from research
2. Apply geographic filters
3. Apply segment/product filters
4. Compare to bottom-up TAM (should be within 30%)

If variance > 30%, investigate and explain differences.

Step 6: Calculate SAM

Apply realistic filters to narrow TAM:

• Geographic: Regions actually serviceable
• Product Capability: Features needed to serve
• Market Readiness: Customers ready to adopt
• Addressable Switching: Can reach and convert

Formula:

SAM = TAM × Geographic % × Product Fit % × Market Readiness %

Step 7: Estimate SOM

Calculate realistic obtainable market share:

Conservative Approach (Recommended):

• Year 3: 2-3% of SAM
• Year 5: 4-6% of SAM

Consider:

• Competitive intensity
• Available resources (funding, team)
• Go-to-market effectiveness
• Differentiation strength

Step 8: Create Market Sizing Report

Generate a comprehensive markdown report with:

Section 1: Executive Summary

• Market opportunity in one paragraph
• TAM/SAM/SOM headline numbers

Section 2: Market Definition

• Problem being solved
• Target customer profile
• Geographic scope
• Time horizon

Section 3: Bottom-Up Analysis

• Customer segment breakdown
• Segment sizing with sources
• TAM calculation with formula
• Assumptions documented

Section 4: Top-Down Validation

• Industry category and size
• Filter application
• Validated TAM
• Comparison to bottom-up

Section 5: SAM Calculation

• Filters applied with rationale
• SAM formula and result
• Segment-level breakdown

Section 6: SOM Projection

• Market share assumptions
• Year 3 and Year 5 estimates
• Customer count implications
• Revenue projections

Section 7: Market Growth

• Industry growth rate (CAGR)
• Key growth drivers
• 5-year market evolution

Section 8: Validation and Sanity Checks

• Public company comparisons
• Customer count validation
• Competitive context

Section 9: Investment Thesis

• Market opportunity assessment
• Key positives and risks
• Venture-scale potential
• Next steps

Step 9: Save Report

Offer to save the report as a markdown file:

• Suggest filename:

  market-opportunity-analysis-YYYY-MM-DD.md

• Use Write tool to create file
• Confirm file location with user

Examples

Example 1: Ask for the upstream workflow directly

Use @startup-business-analyst-market-opportunity to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @startup-business-analyst-market-opportunity against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @startup-business-analyst-market-opportunity for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @startup-business-analyst-market-opportunity using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in

plugins/antigravity-awesome-skills-claude/skills/startup-business-analyst-market-opportunity

metadata.json

ORIGIN.md

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated

SKILL.md

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
