prd-v10-case-study-builderBuild customer case studies as marketing and chasm-crossing reference assets during PRD v1.0 Market Adoption.
Prd V10 Case Study Builder is an agent skill from mattgierhart/PRD-driven-context-engineering. Build customer case studies as marketing and chasm-crossing reference assets during PRD v1.0 Market Adoption. Triggers on requests to build case studies, produce customer stories, create reference content, or when user asks "build a case study", "customer story", "reference account", "case study interview", "before/after story", "social proof page", "logo wall". Outputs CFD-CASE- evidence entries, GTM-CASE- marketing assets, and updates ADO-REF- with story status.
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Product & Project Management, covering Storytelling, PRD writing and Physical and earth sciences. The repository describes itself as: PRD-Led Context Engineering — Memory as Infrastructure. An ontology layer for product teams building products that solve real problems — with AI agents that remember. Gated PRD… The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 30ed1b0. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrepFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Prd V10 Case Study Builder loads about 2.9k tokens when it runs. Until then it costs about 125 tokens; SKILL.md has 1,112 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.
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.

Default is standard. See .claude/rules/08-skill-execution-modes.md for selection logic.
| Mode | What this skill produces |
|---|---|
| quick | Short-format case (testimonial + 1-paragraph story + logo); single placement |
| standard | Full case study (1,500 words) + short and medium derivatives + customer-approved + 3 channel placements |
| deep | Long-form case (2,500–4,000 words) + multi-format derivatives (PDF, blog, video, conference talk) + measurable outcome quantified + outcome-attribution interview |
Turns customer success — already documented as CFD-* evidence and ADO-REF-* candidates — into structured case studies. Case studies are the pragmatist buyer's #1 reference signal: they need to see a customer in their segment achieving the outcome they want, with enough detail to make it credible.
This is an operational "doing" skill, not a strategy skill. The strategic question (which segment, what story angle, what outcome to highlight) was answered by prd-v10-chasm-adoption-moore. This skill produces the artifact.
Customer: Acme Logistics (beachhead segment: freight forwarders, 50-200 employees, US PNW). ADO-REF-002.
Interview: 50 minutes with Acme's VP Operations.
Quantified outcome:
SCQR:
Three formats produced:
| Trigger | Mode |
|---|---|
| First reference customer in beachhead is ready to talk | standard |
| Chasm-crossing push needs 3+ in-segment case studies | deep |
| Pricing-page logo wall expansion | quick (short format only) |
| Sales enablement asset for new segment | standard |
| Investor / partner update | standard |
| Customer success milestone (e.g., 1-year anniversary) | quick |
Do not use for: customers outside beachhead during chasm crossing (their story doesn't resonate with pragmatists); customers without consent (legal risk); customers without quantifiable outcomes (story will feel vague).

| Cold Outreach (Tiered) | Cases referenced in Touch 3 of sequences | Tier 1 outreach mentions in-segment case study |
| Testimonial Collector | Short-format derivatives are testimonial-shaped | Auto-eligible for testimonial walls |
| AEO Audit | Cases become AI-citation sources | High-traffic case pages cited by AI search |
| Sales / Investor | Direct asset for sales calls and investor updates | "Here's how Acme uses [product]" |

SKILL.md names no scripts, command-line tools or credentials: Prd V10 Case Study Builder is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit, Glob, Grep.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Prd V10 Case Study Builder is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.9k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
