What it does
Biz Porters Five Forces is an agent skill from asgard-ai-platform/skills. Apply Porter's Five Forces framework to assess industry competitive dynamics and attractiveness. Use this skill when the user needs to analyze an industry's profitability structure, evaluate market entry barriers, assess supplier or buyer bargaining power, or understand competitive intensity — even if they say 'industry analysis' or 'is this market worth entering' without naming Porter's explicitly.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `examples/sample_scenario.md` and `references/framework-comparison.md`).
It sits in Marketing & SEO, covering Go-to-market strategy and Market research. The repository describes itself as: 301 open-source coding agent skills across 22 domains — methodology, judgment & gotchas packaged as Claude Agent Skills for the Asgard AI Platform. The licence is MIT.
When your agent uses it
- The user needs to analyze an industrys profitability structure
- Evaluate market entry barriers
- Assess supplier
- Buyer bargaining power
Example prompts
- “industry analysis”
- “is this market worth entering”
- “/biz-porters-five-forces”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 4e7f4f8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Biz Porters Five Forces loads about 1.9k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 664 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.
Safety
Auto-check passed
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.

Porter's Five Forces Analysis
Overview
Porter's Five Forces assesses industry-level competitive dynamics by examining five structural forces that determine profitability. Unlike SWOT (company-level) or PESTEL (macro-level), this framework operates at the industry level — it answers "is this industry attractive?" not "is this company strong?"
When to Use
Trigger conditions:
- User asks whether an industry or market is attractive or profitable
- User evaluates whether to enter a new market or industry
- User needs to understand competitive dynamics beyond direct competitors
- User mentions "barriers to entry", "supplier power", or "industry structure"
When NOT to use:
- For company-specific strengths/weaknesses → use SWOT
- For macro-environment scanning → use PESTEL
- For product portfolio decisions → use BCG Matrix
Framework
IRON LAW: Industry-Level, Not Company-Level
Each force describes the INDUSTRY structure, not a specific company's position.
"Our supplier raised prices" is a company event.
"Suppliers in this industry are concentrated with few alternatives" is an industry force.
NEVER analyze a single company's situation — analyze the structural conditions
all players in the industry face.IRON LAW: All Five Forces, Every Time
Analyze ALL five forces before drawing conclusions. Skipping forces produces
misleading assessments. An industry with low rivalry but high substitute threat
is very different from one with low rivalry and no substitutes.Step 1: Define the Industry Boundary
Before analyzing forces, clearly define:
- What industry? Be specific — "food delivery platforms in Taiwan" not "tech"
- Geographic scope: global, regional, or national
- Time horizon: current state or projected 3-5 years
Getting the boundary wrong invalidates the entire analysis.
Step 2: Analyze Each Force
Rate each force as High / Medium / Low pressure on industry profitability:
1. Threat of New Entrants — How easy is it for new players to enter?
- Capital requirements, economies of scale, brand loyalty, regulatory barriers
- Access to distribution channels, switching costs, incumbents' response
2. Bargaining Power of Suppliers — Can suppliers dictate terms?
- Supplier concentration, uniqueness of inputs, switching costs
- Forward integration threat, importance of volume to supplier
3. Bargaining Power of Buyers — Can customers dictate terms?
- Buyer concentration, price sensitivity, product differentiation
- Backward integration threat, switching costs, information availability
4. Threat of Substitutes — Can other products fulfill the same need?
- Price-performance of substitutes, switching costs
- Buyer propensity to substitute, functional equivalence
5. Industry Rivalry — How intense is competition among existing players?
- Number and size of competitors, industry growth rate
- Product differentiation, exit barriers, fixed costs structure
Step 3: Assess Overall Industry Attractiveness
Synthesize the five forces into an overall assessment:
- More forces = High pressure → less attractive (lower profitability)
- More forces = Low pressure → more attractive (higher profitability)
- Identify the dominant force — the one that most constrains profitability
Step 4: Strategic Implications
Based on the analysis:
- Which forces can the company influence or reshape?
- Where should the company position to minimize negative forces?
- What structural changes might shift forces in the future?

Correct Application
Scenario: Five Forces for the Taiwan bubble tea industry
| Force | Pressure | Reasoning |
|---|---|---|
| New Entrants | High | Low capital requirements (~NT$500K to open a shop), minimal regulatory barriers, many franchise options available |
| Supplier Power | Low | Tea leaves and tapioca are commodity inputs with many suppliers; no single supplier has pricing power |
| Buyer Power | High | Zero switching costs for consumers, hundreds of options within walking distance, high price sensitivity |
| Substitutes | Medium | Coffee, convenience store drinks, and home-brewed tea serve similar "afternoon drink" need, but bubble tea has strong cultural preference |
| Rivalry | High | Saturated market with thousands of shops, low differentiation among mid-tier brands, frequent price wars |
Overall: Low attractiveness — high entry threat + high rivalry + high buyer power squeeze margins.
Incorrect Application
Scenario: Same bubble tea industry
What went wrong:
- "Our flagship store has strong foot traffic" → This is a company fact, not an industry force. Violates Iron Law: analyze industry structure, not individual company position.
- Only analyzed "Rivalry" and "New Entrants", skipped other three forces → Violates Iron Law: all five forces required. Missing supplier/buyer/substitute analysis gives incomplete picture.
Gotchas
- Confusing company position with industry structure: "We have a strong brand" is not relevant to Five Forces. "Brand loyalty creates high barriers to entry for the industry" is.
- Overlooking substitutes: Most analysts underweight this force. Ask: "If prices in this industry doubled, what would customers switch to?"
- Static analysis: Five Forces describes current structure. Industries evolve — note emerging shifts (e.g., digital disruption lowering entry barriers).
- Industry boundary too broad: "The food industry" is not analyzable. Narrow to a specific segment with shared competitive dynamics.
- Treating forces as independent: Forces interact. High buyer power + low switching costs amplifies the effect of new entrants.
