v0.3.0: first release (10 method skills + 5 domain packs)

Business Analyst Skills for Claude: first release

AI already knows how to write a requirement. A senior BA knows what to ask in a specific domain. This release packages both: 10 method skills that follow BABOK techniques, and 5 domain packs (Banking, E-commerce, Payments, Lending, Logistics) with the rules, edge cases and stakeholder questions a senior BA would bring. English and Vietnamese.

What is inside

Method skills (how a BA works)
meeting-to-requirements · requirements-linter · functional-decomposition · user-story-writer · bpmn-modeling · ba-diagrams · screen-spec · decision-table · edge-case-finder · api-spec

Domain packs (what a BA must know)
domain-banking · domain-ecommerce · domain-payments · domain-lending · domain-logistics

Highlights

• Token-run simulation (bpmn-modeling): runs scenarios through a BPMN diagram and finds where the process gets stuck, with a lint and AS-IS to TO-BE mode.
• decision-table ships a checker script that finds missing, conflicting and overlapping rule combinations and generates test cases.
• functional-decomposition works from one spec file: lint, Mermaid, SVG, CSV/Jira and an interactive HTML explorer.
• screen-spec writes a screen specification from a mockup image and separates what is visible from what is assumed.
• Skills never invent business rules: unknown values stay as [to confirm] placeholders plus open questions.

Install

• Claude Code: /plugin marketplace add lechithinh/ba-claude-skills then /plugin install ba-claude-skills@ba-claude-skills
• Claude.ai: download the zip of the skill you need and the domain pack that fits, then upload them in Settings, Capabilities, Skills. Each zip is one skill.
• Manual (Claude Code): unzip ba-claude-skills-all.zip and copy the folders in skills/ to ~/.claude/skills/.
• Cursor, Codex, Gemini CLI and others: point the agent to AGENTS.md (included in the all-in-one zip).

Downloads

File	Contents
ba-claude-skills-all.zip	All 15 skills, AGENTS.md, license
<skill-name>.zip	One skill (for example decision-table.zip, domain-banking.zip), each with its license

Known limitations

• Domain knowledge and the regulation files are community drafts written from general industry practice. They have not yet been reviewed by practitioners in each industry, and regulation files list topics to ask Compliance or Legal about, not legal advice.
• The scripts, examples and diagrams are validated, but the skills have not yet been checked for automatic activation across many fresh sessions. Feedback on real projects is very welcome.
• Domain packs have a Vietnam focus; each company's rules differ.
