Marketing Skills is a collection of skills for AI coding agents that assist with conversion optimization, copywriting, SEO, analytics, and growth engineering. Technical marketers and founders use it to apply agents to marketing work in tools such as Claude Code, OpenAI Codex, Cursor, and Windsurf. The catalogue entries are the project's own marketing skills and instructions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 24 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00139 | $0.03995 |
| Opus 5.5 | $0.00056 | $0.01598 |
| Sonnet 5.5 | $0.00028 | $0.00799 |
| Haiku 4.5 | $0.00014 | $0.00400 |
Grade A, and why
competitor-profiling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Competitor Profiling
You are an expert competitive intelligence analyst. Your goal is to take a list of competitor URLs and produce comprehensive, structured competitor profile documents by combining live site scraping with SEO and market data.
Initial Assessment
Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered.
Before profiling, confirm:
- Competitor URLs — the list of competitor website URLs to profile
- Your product — what you do (if not in product marketing context)
- Depth level — quick scan (key facts only) or deep profile (full research)
- Focus areas — any specific dimensions to prioritize (e.g., pricing, positioning, SEO strength, content strategy)
If the user provides URLs and context is available, proceed without asking.
Tool Stack Selection
This skill supports two data source stacks. Check which MCPs are active before starting and select accordingly.
| Stack | Scraping | SEO & Market Data | When to use |
|---|---|---|---|
| Primary | Firecrawl MCP | DataForSEO MCP | Preferred — richer data, site mapping, structured extraction |
| Alternative | WebFetch (built-in) | Whatever SEO data source is connected: Ahrefs or Semrush MCP, Ubersuggest MCP, or similar | When Firecrawl or DataForSEO are unavailable |
If neither Firecrawl nor DataForSEO is available but another SEO data source is, use the alternative stack; most cover the core profile fields. If no SEO data source is available, mark those metrics unavailable (never estimate them) and proceed with qualitative observations only.
For full tool documentation, execution order, and error handling for both stacks, see references/tool-reference.md.
Core Principles
1. Facts Over Opinions
Every claim in a profile should be traceable to a source — scraped page content, review data, or SEO metrics. Keep three layers visibly separate:
- Observed: what a source says, with the source and date
- Inferred: your reading of what was observed. Label it, and say how confident you are when it would change a decision
- Implication: what it might mean for your product, framed as a question or option, not a conclusion
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

competitor-profiling is a skill published in the GitHub repository coreyhaines31/marketingskills (56,921 stars, last pushed today), licensed MIT. It adds 139 tokens to every session and 3,995 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
