Business Case Study Public

Public Case Study (tier 3)

Turn a run package into a case study fit for external publication. Tier 3 is the hard sanitization tier: no internal identifiers of any kind, aggregates and ranges only, every headline claim triangulated. Value is engineer-hours, cycle time, and capacity; never money.

Read references/interim-format.md first — it defines run location and the completeness gate. Defer these rendering references until the gate passes; a refused render never loads them:

• references/provenance.md — tag rendering, anti-inflation rules, the no-currency contract.
• references/evidence.md — the external evidence table and the triangulation procedure.
• references/audiences.md — the tier-3 contract and the final checklist.

User arguments: $ARGUMENTS

Context

Recent runs — run this command and read the output:

sh -c 'ls -dt "$HOME"/Documents/*/business/ /mnt/c/Users/*/Documents/*/business/ 2>/dev/null' | head -5 | grep . || echo "(no runs found)"

Procedure

1. Locate the run

Use the $ARGUMENTS path if given, else the newest run per interim-format.md. Confirm the choice with the user.

2. Completeness gate

Run the completeness gate from interim-format.md. Refuse to render from an incomplete package; list what is missing and stop.

3. Draft under the tier-3 contract

Read the deferred references above, then draft the case study in this order — sanitized from the first word, not sanitized afterwards:

1. Context — the kind of team and the kind of task, described without identifying anyone or anything internal.
2. Approach — what was built, in transferable terms.
3. Results — aggregates and ranges only; every figure tagged as tag plus method phrase per audiences.md; denominators and pinned-window lengths stated; honest rounding.
4. Limitations — candid and mandatory: measurement weaknesses, the counterfactual rung, what was not measured. Credibility is the PR asset.

4. Triangulate every headline claim

Apply the triangulation procedure from evidence.md to each headline claim. A claim outside the defensible external range is removed or kept only with an explicit methodology defense. Record each outcome.

5. Final checklist pass

Run the tier-3 final checklist from audiences.md over the finished draft as an explicit pass, item by item. Fix every hit, then write <run>/reports/case-study-public.md.

Output

Open with a one-line hero (✓ Public case study: <headline with tag>, ✓ Evidence report: <supported claim, unknowns named>, or ⚠ Refused: <reason>), then exactly these sections:

1. ## Run — the run chosen and its pinned window.
2. ## Gate — the completeness result.
3. ## Sanitization — the checklist results item by item, and the triangulation outcome per headline claim.
4. ## Report — where it was written and the headline.

End with an ask-user-choice panel: derive the PR release next, tighten a claim, or stop. Skip the panel in plan mode or when running non-interactively.

Portability notes

• ask-user-choice — present the listed options and wait for the user to pick one. Hosts with a structured multiple-choice tool (Claude Code's AskUserQuestion) should use it; otherwise print a numbered list and wait for a numbered reply. Never proceed on an assumed answer.
• $ARGUMENTS — the text the user passed when invoking this skill. If your host does not substitute it, read it as the user's request in the current turn, and ask when there is none.
• Bundled files — every relative path in this skill points at a file shipped inside this skill directory. Read them from here, not from the host's plugin tree.
