cskwork Ten Rules
A router over thirty-nine "10 rules" reference sets in ref/ — seventeen cross-cutting disciplines
plus twenty-two industry verticals. Before doing the work, load the rules that match the task, apply
their checklists, then execute.
1. Route the task
Match the strongest signal to a domain. If several apply (e.g. an LLM product launch page = ai-engineering + web-design + growth-marketing), start with the strongest domain; load another index only for a distinct requirement.
Core sets

Industry verticals — building a site or software for a specific industry. Layer these on top of the disciplines above (e.g. an online pharmacy = ecommerce-retail + healthcare-digital-health + data-privacy-legal; a Palantir-style tool = enterprise-data-platform + security + b2b-saas).

No domain matches → this skill does not apply; proceed normally.
2. Apply (same for every domain)
- Read the domain
INDEX.md. Pick the 1–5 rules that actually bear on this task. - Read only those full rule files (each has Why / How to apply / Checklist).
- Mention selected rules only when they explain a material decision or the user requested an audit.
- Apply the relevant checklist items within the user's requested scope; do not turn an example or general rule into unrequested work.
- Self-check: walk every item on those checklists, name each gap, and fix it before claiming done.
3. Notes
- investment has overlays — load
kr-equity/only for Korean (KOSPI/KOSDAQ) stocks, andquant-bot/only for an automated/agentic trading system. - coding duplicates the Ten Commandments already in
~/.claude/CLAUDE.md. Skip it unless the user explicitly asks, or you are running outside Claude Code (e.g. Codex/Gemini) without those rules. - The five core sets are vendored snapshots of
github.com/cskwork/{web-design-10-rules, communication-10-rules, investment-agent-rules, planning-doc-rules, coding-agent-rules}— refresh withscripts/refresh.sh. The twelve builder-stack sets and the twenty-two industry verticals are authored in-repo from recognized authorities (OWASP, Google SRE/AIP, NIST, Kimball, Nielsen Norman, GDPR, Baymard, Mayer, Kleppmann, ISA-95, HL7 FHIR, PCI-DSS, IATA NDC, GOV.UK Service Standard, et al.) cited in each rule's References;refresh.shdoes not touch them.
