At a glance
Turns a client win into case studies, proposal blurbs, social proof quotes and sales stories, after collecting the details and at least one concrete number.
- Works in 5 steps: Situation Analysis → The Hero Principle → Generate Three Formats → …
- Documenting a client result for a proposal or sales call
- SKILL.md covers Mode, Context Loading Gates, Phase 1: Situation Analysis and Phase 2: The Hero Principle, plus 4 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The skill has three modes. Quick gives one paragraph for proposals, standard is the default and gives a proposal blurb, a social proof pull-quote and a sales story, and deep adds a blog-ready case study, an FAQ variant and campaign assets. Before drafting it collects eight fields: client, the before state, actions taken, the after result, timeline, a client quote, whether the client may be named and where the piece will be used.
The after field must contain at least one specific number, and if you only say results were good, the agent stops and asks for revenue change, time saved or lead volume, accepting a rough estimate. A situation analysis then rates result strength, checks that the client is the hero and the author the guide, and looks for the tension that makes a story. A SKILL-OC.md variant is bundled.
When your agent uses it
- Documenting a client result for a proposal or sales call
- Creating a social proof pull-quote from a finished project
- Turning a win into a blog-ready case study with an FAQ
Example prompts
- “Write a quick case study from my website redesign for a dental clinic; leads went from 0 to 5 a month.”
- “Build a standard case study package for our onboarding automation project.”
- “Turn this client win into a deep asset set for the blog, including an FAQ variant.”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Situation Analysis
- The Hero Principle
- Generate Three Formats
- Self-Critique Pass (REQUIRED)
- Distribution Plan
What it can do on your machine
Read from SKILL.md and the folder at commit f36b34f. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Case Study Builder loads about 1.8k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 754 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.
Safety
Auto-check passed
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 754 words (~1,769 tokens).
“Everyone wants social proof. Nobody makes time to create it. You finish a project, the client's happy, you move on — and six months later you're in a sales call with nothing to show.”
