Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Case Study Builder with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 21, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 577deba

Fetched SKILL.md via raw GitHub; frontmatter has name+description, single self-contained file, no scripts/hardcoded paths, no security smells (only an optional cross-reference to testimonial-collector, which exists in the repo tree). Ran one representative task (a 12-person law firm intake-automation win) twice: a baseline case study ignoring the body, and a skill-followed run in standard mode. Baseline was one flat narrative opening "We built..." ending on vague "freed up significant staff time"; skill output produced three distinct deployable formats plus a Tier-1 result classification, self-critique pass, and distribution plan, and flipped framing to client-as-hero. Both artifacts saved to scratchpad (csb_baseline.md, csb_skill.md).

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 8/10
Docs & honesty 5/5

What Case Study Builder does

Converts raw project-win details into three formatted proof assets: a two-line proposal blurb, a 150-250 word story version, and a full markdown case study. Enforces at least one concrete outcome number before drafting and classifies result strength into a 4-tier language system. Triggers when someone wants to document results, build sales credibility, or create reusable social proof.

How to install Case Study Builder

git clone --depth 1 https://github.com/BrianRWagner/ai-marketing-claude-code-skills.git /tmp/case-study-builder-src
mkdir -p ~/.claude/skills
cp -R /tmp/case-study-builder-src/case-study-builder ~/.claude/skills/case-study-builder
# Self-contained single SKILL.md, no scripts or external deps.
# Body cross-references a `testimonial-collector` skill (also in this repo) as an optional next step; not required to run.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
