Four methodology-grade skills for Claude Cowork. Free, open source, no account required.
All three skills in a single guided flow. Produces one ba-skills-bundle.json with capabilities, concepts, value streams, roles, and metrics. Start here.
MECE capability hierarchy. BIZBOK-grounded. L1–L3 with Execution/Governance split. Interactive treemap output.
Business object taxonomy using the Capsicum Triad (Party / Record / Resource). Interactive graph output.
Staged value delivery with outcome chain, capability mapping, PPIT breakdown. Interactive stage view + JSON export.
Download each .skill file below. These are the native Cowork format — upload directly, no unzipping needed.
Using Claude Code instead? Download the .zip versions and unzip into ~/.claude/skills/.
In Cowork, open the Skills menu, then click Upload skill. Select a downloaded .skill file — Cowork will confirm installation with a toast notification.
Repeat for each of the four skills. No unzipping needed.
Open a new Cowork task and type / in the chat. You should see all four commands: /plausibleba, /capability-map, /concept-model, and /value-stream.
.skill files from this page, remove the old skills in Cowork (Customize → Skills → ··· → Remove), then upload the new files.
If you prefer to install from GitHub, you can add the PlausibleBA marketplace directly. Note: this method may not work with all Cowork versions.
In Cowork, open the Skills menu from the main interface.
Click Add marketplace and enter: plausibleba/ba-skills
Click each skill card and press Install. If this fails, use the zip upload method above — it's the most reliable option.
Click New task in the left sidebar. This is essential — skills use conversation context. Running a skill in an existing task will cause Claude to reference prior outputs rather than eliciting from your new input. Always start fresh for each domain or session.
Any description works — a pitch deck, project brief, business plan, meeting notes, or a few paragraphs written from memory. The skill will ask clarifying questions if it needs more.
/plausibleba — recommended — runs all three skills in sequence, exports a single bundle
/capability-map — MECE capability hierarchy with interactive treemap
/concept-model — business object taxonomy with interactive graph
/value-stream — staged value stream with interactive stage view
The skill guides you through two validation checkpoints before rendering. The visualisation appears automatically.
After the visualisation renders, the skill automatically generates an XLSX workbook and a JSON bundle — both appear as clickable download links, no extra prompt needed. You'll also see suggested next steps to run companion skills (e.g. Concept Model → Value Stream) so you can build the full business architecture stack in sequence.
Run /capability-map first, then /concept-model — the concept model cross-validates that every business object is grounded in a capability. Then /value-stream to orchestrate them into delivery.
All three skills in the same Cowork task automatically use the outputs from previous skills — richer cross-validation without re-entering context.
Each skill pauses twice for your review. These checkpoints are where your domain knowledge matters most — don't skip them.
A capability map your stakeholders immediately recognise builds far more confidence than a technically correct one that feels unfamiliar.
Cowork requires a Claude Max, Team, or Enterprise plan. The skills run on Claude Opus 4 by default within Cowork tasks.
Yes. The skills are domain-agnostic — tested across property management, food delivery, financial services, insurance, and public sector. The methodology is BIZBOK-grounded, which means it applies wherever you need to describe what a business does, what it manages, and how it delivers value.
The Capsicum Triad classifies all business objects into three root types: Party (a person or organisation that plays a role), Resource (a thing of value that is managed or exchanged), and Record (a document that captures evidence of something that happened). Grounded in REA theory (McCarthy 1982) and Bunge's ontology.
VCC (Value Cognition Canvas) is a business architecture platform that accepts the ba-skills-bundle.json export from these skills, adding friction heatmaps, solution mapping, throughput projections, and governance controls. Learn more →
