reverse-engineer-marketing
reverse-engineer-marketing is a skill in coreyhaines31/marketingskills, last changed 30 Oct 2026. It can handle money, run shell commands, reach the network, name web addresses and bundle scripts — read the findings before installing.
When the user wants to reverse engineer how another company grew and copy what worked. Also use when the user mentions 'reverse engineer,' 'how did X grow,' 'how does X get customers,' 'growth teardown,' 'marketing teardown,' 'GTM teardown,' 'growth blueprint,' 'what is X doing for marketing,' 'what made X take off,' 'copy X's playbook,' 'X's distribution strategy,' 'what content works for X,' 'funnel hack,' 'map their funnel,' or 'watch what X is doing.' Builds a dated log of a company's moves against its traffic curve from public data, sign-ups and demos, team interviews, and hidden signals (DNS, certificate logs, archives, sponsorships), compares it with the user's own data, and turns what lined up with growth into plays routed to the skill that runs each one.

Pattern check
Pattern check: nothing flagged · commit 88c79f6 · 31 Oct 2026
We checked every text file in this skill, at commit 88c79f6 on 31 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses with warnings
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Warning
The body is about 6,096 tokens (approx.); the spec suggests under 5,000. B2
Fix: Move detail into reference files that the agent reads only when needed.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
There is no license field, so readers can't tell whether they may reuse the skill. O2
Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
- Note
Reference files over 100 lines with no table of contents at the top: references/playbook-template.md (134 lines). B5
Fix: Add a short list of the sections at the top of each.
- Note
Line 222 has dated wording ("since 2024"), which goes stale. B8
Fix: Describe the current way, and move old patterns into their own clearly marked section.
- Warning
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
The body is about 6,096 tokens (approx.); the spec suggests under 5,000. After compaction Claude Code keeps only the first 5,000 tokens of a skill. B2
Fix: Move detail into reference files that the agent reads only when needed.
- Note
Reference files over 100 lines with no table of contents at the top: references/playbook-template.md (134 lines). B5
Fix: Add a short list of the sections at the top of each.
- Note
Line 222 has dated wording ("since 2024"), which goes stale. B8
Fix: Describe the current way, and move old patterns into their own clearly marked section.
- Note
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
The description is 961 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
The body is about 6,096 tokens (approx.); the spec suggests under 5,000. Anthropic's guidance says the same. B2
Fix: Move detail into reference files that the agent reads only when needed.
- Note
Reference files over 100 lines with no table of contents at the top: references/playbook-template.md (134 lines). B5
Fix: Add a short list of the sections at the top of each.
- Note
Line 222 has dated wording ("since 2024"), which goes stale. B8
Fix: Describe the current way, and move old patterns into their own clearly marked section.
- Note
OpenAI (Codex & API)Passes
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
VS Code & CopilotPasses
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Note
Anthropic's packaging script leaves these out: evals/. F8
Fix: Delete them, or list them in .gitignore.
- Note
SKILL.md
