# ADR-008: Business-process tooling (C10)

- **Status:** Accepted
- **Date:** 2026-05-17
- **Deciders:** Дмитрий

## Context

The `C10 «Бизнес-процессы (общее)»` map section had zero tooling. C10 is the
catch-all of bucket C — its work (modeling, automation, analysis of business
processes) partly overlaps already-populated sections (C9 PM, E2 orchestration,
A6 diagrams). A toolset is needed without duplicating those.

## Decision

C10 adopts a hybrid toolset (Approach 3):

- **operations plugin** (`operations@knowledge-work-plugins`, Anthropic) —
  process documentation, change management, capacity planning.
- **process-modeling skill** — self-authored vendored skill: BPMN 2.0, process
  maps, RACI, state-machines. Renders via the mermaid skill.
- **process-analysis skill** — self-authored vendored skill: as-is discovery,
  bottlenecks, traceability, BP metrics.
- **Five reuse cross-references** (mermaid, architecture-patterns, CCPM,
  product-management, writing-plans) surfaced via `NODE_SECTION_SECONDARY` — no
  re-tagging of their home sections.
- **n8n-mcp** (workflow engine) is **deferred**: the portal stack has no n8n
  (the process engine is the Laravel queue); adopting n8n is an architecture
  decision with its own ADR. n8n-mcp is a reserved registry slot.
- C10 tools are non-UI → the `business-process` off-phase category, outside the
  PSR_v1 UI-pool.

## Consequences

- Positive: C10 populated; modeling + automation + analysis covered with zero
  duplication of C9/E2/A6 tools.
- Risk: the two skills are self-authored — owned by the project, no upstream
  dependency (this is the mitigation, not a risk).
- Deferred: no workflow engine until n8n is adopted as infrastructure — accepted,
  this is the decision.

## Enforcement

None — C10 tools are advisory; verified by use and code review.
