competitive-analyzerCompetitive landscape analysis: Porter's Five Forces, competitor discovery, feature/pricing matrices, positioning maps, moat assessment via WebSearch.
Competitive Analyzer is an agent skill from Mathews-Tom/armory. Competitive landscape analysis: Porter's Five Forces, competitor discovery, feature/pricing matrices, positioning maps, moat assessment via WebSearch. Triggers on: "competitive analysis", "competitor comparison", "competitive landscape", "Porter's Five Forces", "market positioning", "moat assessment", "defensibility analysis".
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/cases.yaml`, `references/competitive-matrix.md` and `references/porters-five-forces.md`).
It sits in Marketing & SEO, covering Positioning and messaging and Competitor analysis. The repository describes itself as: Curated, production-grade skills for AI coding agents. Battle-tested workflows for developers who use AI seriously. The licence is MIT.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 4594fb7. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs 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.
Competitive Analyzer loads about 2.8k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 1,038 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.

| General web research and data gathering | tavily / web-fetch |
Identify competitors across three tiers using WebSearch.
Tier classification:
"[product category] alternatives", "[product] vs", "best [category] tools 2024""how to [solve problem] without [category]", adjacent category leadersDiscovery sources:
site:producthunt.com [category]site:g2.com [category] reviewssite:capterra.com [category]site:crunchbase.com [category] fundingOutput: A competitor roster table:
| Competitor | Tier | Founded | Funding | HQ | Est. Revenue | Target Segment |
|---|
Include 5-15 competitors. Fewer than 5 suggests the search was too narrow; more than 15 suggests the scope needs tightening.
Score each force 1-5 with supporting evidence. Reference references/porters-five-forces.md for scoring rubric and sub-criteria.
1. Threat of New Entrants (1-5)
2. Supplier Power (1-5)
3. Buyer Power (1-5)
4. Threat of Substitutes (1-5)
5. Competitive Rivalry (1-5)
Synthesis: Calculate overall industry attractiveness (weighted average of forces). Higher scores mean more competitive pressure, lower attractiveness.
Build a comprehensive comparison. Reference references/competitive-matrix.md for structuring methodology.
Feature comparison table:
| Feature Category | Feature | Competitor A | Competitor B | Competitor C | Our Product |
|---|---|---|---|---|---|
| Core | Feature 1 | Full | Partial | None | Full |
| Integration | API | REST | GraphQL | None | REST+GraphQL |
| Support | SLA | 99.9% | 99.5% | None | 99.95% |
Use: Full / Partial / None / Superior (exceeds category standard)

Reference references/positioning-analysis.md for dimension selection and mapping methodology.
Step 1: Dimension selection Select the two dimensions most important to target customers. Common pairs:
Validate dimension selection against customer research or publicly available review themes.
Step 2: Plot competitors Position each competitor on the 2D map using evidence from Phase 3.

Evaluate each moat type. Reference references/positioning-analysis.md for the moat taxonomy.
| Moat Type | Present? | Strength | Evidence |
|---|---|---|---|
| Network effects | Yes/No | Weak/Moderate/Strong | Description |

Overall moat rating:
Produce the final competitive analysis report with these sections:
Before delivering the report, verify:
| Situation | Adaptation |
|---|---|
| Pre-launch product with no direct competitors | Focus on indirect competitors and substitutes. Emphasize the "potential entrants" tier. The absence of direct competitors is itself a signal worth analyzing (nascent market vs. no market). |
| Highly fragmented market (50+ competitors) | Segment competitors into strategic groups. Analyze 2-3 representative competitors per group rather than every player. |
| Monopoly or duopoly market | Five Forces analysis becomes more important. Focus on substitute threats and potential entrants. Analyze the dominant player's moats in detail. |
| B2B enterprise with opaque pricing | Note pricing opacity as a finding. Use job postings, case studies, and review sites for indirect pricing signals. |
| User provides a competitor list | Skip discovery in Phase 1. Validate the list for completeness (are there missing tiers?) and proceed to Phase 2. |
| Rapidly changing market | Date-stamp all findings. Flag data older than 6 months as potentially stale. Emphasize monitoring recommendations. |

Run `npx skills add Mathews-Tom/armory --skill competitive-analyzer -a claude-code`. Or copy the skill folder (skills/competitive-analyzer in Mathews-Tom/armory) into .claude/skills/competitive-analyzer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Mathews-Tom/armory --skill competitive-analyzer -a codex`. Or copy the skill folder (skills/competitive-analyzer in Mathews-Tom/armory) into .agents/skills/competitive-analyzer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Mathews-Tom/armory --skill competitive-analyzer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/competitive-analyzer, .gemini/skills/competitive-analyzer, .github/skills/competitive-analyzer and .opencode/skills/competitive-analyzer in your project.
SKILL.md names no scripts, command-line tools or credentials: Competitive Analyzer is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Competitive Analyzer is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 8.2k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Competitive Analyzer: Startup Design (ferdinandobons/startup-skill, 1.2k stars), Competitor Teardown (irinabuht12-oss/marketing-skills, 3.9k stars), Competitive Analysis (w95/awesome-claude-corporate-skills, 237 stars) and Competitor Researcher (hanzili/hanzi-browse, 177 stars).
