cli-hub-matrix-knowledge-research

Knowledge / Office / Research Matrix (S2 — v2 capability-based)

Scenario S2. Strongest coverage in the current ecosystem: search, reference management, notes, synthesis, documents, and diagrams all have first-party harnesses; Python/native fallbacks fill the rest.

Schema: docs/cli-matrix/matrix_registry.schema.md. Matrix plan: docs/cli-matrix/cli-matrix-plan.md.

Install

cli-hub matrix install knowledge-research
cli-hub matrix info    knowledge-research
cli-hub matrix preflight knowledge-research --json

---

Provider selection constraints

1. Use preflight as an availability report, not as a provider selector.
2. Treat provider order as documentation order only.
3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

Offline context? Filter to offline: true providers.
