Skill Routing Arbitrator

Disambiguator for when multiple skills could match the same user prompt. Use when uncertain which of several overlapping skills to invoke — e.g., code review (engineering:code-review vs ecc:code-review vs ecc:python-review vs review), security audit (ecc:security-review vs anthropic-skills:security-audit-engine vs ruflo-security-audit:audit), MCP server building (anthropic-skills:mcp-builder vs ecc:mcp-server-patterns), or any case where two or more skills' descriptions match the user's request. Returns the canonical preferred skill and explains why.

Skill Routing Arbitrator

When multiple skills could fire on the same prompt, this skill provides deterministic preferences so Claude routes to the right one.

Priority hierarchy (general)

Most specific language/domain wins over generic — e.g., ecc:python-review over ecc:code-review
Active executor wins over strategy/workflow doc — e.g., ecc:code-review (runs review) over engineering:code-review (strategy)
Current version wins over dated snapshot — e.g., anthropic-skills:mcp-builder over anthropic-skills:mcp-builder-20260419
Real skill wins over legacy shim — e.g., ecc:tdd-workflow over ecc:tdd shim
Connected-data-source skill wins when data is available — e.g., common-room:account-research if Common Room MCP is connected, else sales:account-research

Specific cluster rules

Code review

Situation	Skill
Language known + active review needed	`ecc:<lang>-review` (cpp, python, go, rust, kotlin, flutter)
PR / multi-agent comprehensive	`ecc:review-pr`
Local diff review	`ecc:code-review`
PR triage (lightweight built-in)	`review`
Security focus on PR	`security-review`
Codebase security review	`ecc:security-review`
Strategy / process discussion only	`engineering:code-review`

Testing

Situation	Skill
TDD in language X	`ecc:<lang>-test`
E2E specifically	`ecc:e2e-testing`
Generate tests from existing file	`ruflo-testgen:testgen`
Identify coverage gaps	`ruflo-testgen:test-gaps`
Strategy / test plan	`engineering:testing-strategy`

Build error resolution

Pick by language: ecc:cpp-build / go-build / kotlin-build / rust-build / flutter-build / gradle-build.

Security audit

Situation	Skill
Codebase review (vulnerabilities in code)	`ecc:security-review`
Dependency / supply chain CVE	`ruflo-security-audit:dependency-check`
Formal SOC 2 / ISO 27001 / HIPAA readiness	`anthropic-skills:security-audit-engine`
Smart contract / DeFi	`agency-agents-fork:compliance-audit-routing` → `blockchain-security-auditor`
Healthcare PHI in code	`ecc:healthcare-phi-compliance`
LLM trading agent security	`ecc:llm-trading-agent-security`
Bug bounty mode	`ecc:security-bounty-hunter`
PR-context lightweight	`security-review`

Documentation

Situation	Skill
Library / API docs lookup	`ecc:documentation-lookup` (NOT `ecc:docs` shim)
Auto-generate from code	`ruflo-docs:doc-gen` or `ruflo-docs:api-docs`
Plan documentation strategy	`engineering:documentation`
RuFlo-managed project	`ruflo-docs:ruflo-docs`

Document generation by file format

Always prefer format-specific:

PDF → anthropic-skills:pdf
PPTX → anthropic-skills:pptx
DOCX → anthropic-skills:docx
XLSX → anthropic-skills:xlsx

For code-generated mixed-format documents with charts → specialized-document-generator agent (via knowledge-content-routing).

Brand voice

Situation	Skill
Search platforms for brand materials	`brand-voice:discover-brand`
Generate guidelines from materials	`brand-voice:generate-guidelines`
Apply guidelines to content	`brand-voice:enforce-voice`
Review existing content for brand fit	`marketing:brand-review`
Anthropic-branded artifact (colors/typography)	`anthropic-skills:brand-guidelines`

MCP server building

Situation	Skill
New MCP server	`anthropic-skills:mcp-builder`
Pattern reference	`ecc:mcp-server-patterns`
Snapshot (don't use)	`anthropic-skills:mcp-builder-20260419`

Skill creation pipeline

Stage	Skill
Author new skill	`anthropic-skills:harness-skill-builder`
Review pre-package	`anthropic-skills:skill-review-gate`
Package as patch/upgrade	`anthropic-skills:skill-upgrade-pipeline`
Patch exam engine	`anthropic-skills:exam-engine-patcher`
Extract from git history	`ecc:skill-create`
Compliance scan on skills	`ecc:skill-comply`
Portfolio dashboard	`ecc:skill-health`
Inventory	`ecc:skill-stocktake`

Planning / execution

Canonical PRP flow: ecc:prp-prd → ecc:prp-plan → ecc:prp-implement → ecc:prp-pr → ecc:prp-commit.

Alternatives:

Multi-agent agency engagement → agency-agents-fork:strategy-nexus
Agent-to-agent handoff doc → anthropic-skills:work-order-drafter
Lightweight restate + plan → ecc:plan

Compliance (route by domain)

Domain	Skill
SOX testing	`finance:sox-testing`
Financial audit support	`finance:audit-support`
HIPAA in code	`ecc:hipaa-compliance`
Healthcare PHI	`ecc:healthcare-phi-compliance`
Legal contract compliance	`legal:compliance-check`
Operational tracking	`operations:compliance-tracking`
Smart contract / n8n	`agency-agents-fork:compliance-audit-routing`
Formal SOC 2 / ISO 27001	`anthropic-skills:security-audit-engine`
Skill ecosystem compliance	`ecc:skill-comply`

Sales / account research

Situation	Skill
Common Room MCP available	`common-room:account-research` / `compose-outreach` / `call-prep` / `weekly-prep-brief`
No Common Room data	`sales:account-research` / `draft-outreach` / `call-prep`
Methodology depth (MEDDPICC etc.)	`agency-agents-fork:sales-methodology-routing`

Memory / session

Situation	Skill
Working memory edits	`productivity:memory-management`
Cleanup / consolidate	`anthropic-skills:consolidate-memory`
Save session state	`ecc:save-session`
Resume session	`ecc:resume-session`
Pre-compaction prep	`ecc:strategic-compact`
RAG memory CRUD	`ruflo-rag-memory:ruflo-memory`
RAG semantic recall	`ruflo-rag-memory:recall`

Always avoid

Legacy shims: ecc:tdd, ecc:e2e, ecc:eval, ecc:docs, ecc:devfleet, ecc:claw, ecc:orchestrate, ecc:prompt-optimize — use the destination skill directly
Dated snapshots: *-20260418, *-20260419 suffixes — use the current version
