competitors makes your assistant build pages that position your product against others. It covers four formats: a singular alternative page, plural alternatives, you vs a competitor, and one competitor vs another. Each format has a search intent, URL pattern and page structure, plus essential sections such as a TL;DR, feature and pricing comparison, who it is for and a migration section.

Its Evidence Discipline rules are the point to know before you use it. For example, a feature missing from a pricing page is written as 'not listed' with a date, not as 'doesn't have'. It can also run a Competitive Asset Audit that marks each claim Current, Changed, Unverifiable or Overclaimed. It bundles content-architecture and templates references and an evals/evals.json file, and no scripts.

Good for

SEO and content marketers building vs and alternative pages
Product marketers who keep battle cards and comparison tables
Founders who want honest, defensible competitor claims

What's in the skill

When it loads

When the user wants to create competitor comparison or alternative pages for SEO and buyer-facing use. Also use when the user mentions 'alternative page,' 'vs page,' 'competitor comparison,' 'comparison page,' '[Product] vs [Product],' '[Product] alternative,' 'competitive landing pages,' 'how do we compare to X,' 'competitor teardown,' 'audit our competitor pages,' 'are our comparison pages out of date,' or 'competitive asset audit.' Use this for any content that positions your product against competitors. Covers four formats: singular alternative, plural alternatives, you vs competitor, and competitor vs competitor. For auditing existing claims (not researching competitors from scratch, which is competitor-profiling; not technical SEO on these pages, which is seo-audit), use the asset audit here. For internal battle cards and sales-specific competitor docs, see sales-enablement.

Questions

What does the competitors skill do?

It writes competitor comparison and alternative pages, and audits existing competitive content. It is built to keep claims about other companies accurate and dated.

How do I install the competitors skill?

Use the install box at the top of this page. The repo's README also offers a Claude Code plugin called marketing-skills that installs every skill in the collection, and a Codex plugin route for the same set. Pick one skill only if you want just this one. If you ask an agent session to run npx skills for you, the README says to pass -a claude-code, because the CLI may otherwise install only to .agents/skills/, which Claude Code does not read.

Do I need the product-marketing skill first?

No. The competitors SKILL.md says to read your product marketing context file if one exists, and to ask you for anything the file does not cover. The README calls product-marketing the foundation that the other skills check first, so it helps to run it once.

Does it browse competitor sites?

The audit step says to re-verify each claim against the competitor's current site, docs or changelog. If your assistant cannot browse, it marks claims unchecked and lists what to verify.

How is it different from competitor-profiling?

The description sends researching competitors from scratch to competitor-profiling, and internal battle cards to sales-enablement. This skill builds the buyer-facing pages and audits existing claims.

Does it work in Codex, Cursor or only Claude Code?

The README says the collection works with Claude Code, OpenAI Codex, Cursor, Windsurf, and any agent that supports the Agent Skills spec. It does not list test results per skill.

Is the competitors skill safe to install?

It is a markdown skill. The folder bundles reference files and an evals/evals.json file, and no scripts. The SKILL.md names no API key. It changes how your assistant works in your project, so read the SKILL.md if you need to review it first.
