/concept-model

BA Concept Model

Business object taxonomy using the Capsicum Triad (Party / Record / Resource). Interactive graph output.

/value-stream

BA Value Streams

Staged value delivery with outcome chain, capability mapping, PPIT breakdown. Interactive stage view + JSON export.

Installation
1
2

Upload each plugin to Cowork

In Cowork, click Customize in the left sidebar, then Skills. Click Browse plugins, select the Personal tab, then click + and choose Upload plugin.

Select the first .zip file. Cowork will confirm installation with a toast notification. Repeat for each of the four plugins.

3

Verify installation

Open a new Cowork task and type / in the chat. You should see all four commands: /plausibleba, /capability-map, /concept-model, and /value-stream.

Updating skills: Download the latest zips from this page, remove the old plugins in Cowork (Customize → Skills → ··· → Remove), then upload the new zips.

GitHub marketplace install (alternative)

If you prefer to install from GitHub, you can add the PlausibleBA marketplace directly. Note: this method may not work with all Cowork versions.

1

Open Browse Plugins

In Cowork, click Customize → Skills → Browse plugins. Select the Personal tab.

2

Add the PlausibleBA marketplace

Click +, then enter: plausibleba/ba-skills

3

Install each skill

Click each skill card and press Install. If this fails, use the zip upload method above — it's the most reliable option.


Running your first skill
1

Open a new Cowork task

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.

2

Paste your business description

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.

3

Type a slash command and press Enter

/plausiblebarecommended — 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.

4

Download or export

After the visualisation renders, the skill offers to download an XLSX workbook or export JSON for the VCC pipeline. Both are on demand — the visualisation is the primary deliverable.


Tips for best results

Run the skills 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.

Use a single task for a domain

All three skills in the same Cowork task automatically use the outputs from previous skills — richer cross-validation without re-entering context.

Validate at every checkpoint

Each skill pauses twice for your review. These checkpoints are where your domain knowledge matters most — don't skip them.

Start with a known domain

A capability map your stakeholders immediately recognise builds far more confidence than a technically correct one that feels unfamiliar.


Frequently asked questions

Do I need a specific Claude plan?

Cowork requires a Claude Max, Team, or Enterprise plan. The skills run on Claude Opus 4 by default within Cowork tasks.

Can I use these on any domain?

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.

What is the Capsicum Triad?

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.

What is the VCC pipeline?

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 →

Are the skills free?

Yes. PlausibleBA is free and open source under CC BY-SA 4.0. VCC has its own pricing for advanced analytical features.
