## About

# Deep Research

This is a **Modular Reasoning Workflow Skill**. It preserves the governing semantics of Reasoning Workflow but is intentionally scoped to one Family. Use only the references needed for the current gap; do not bulk-load the folder.

User instructions and hard safety/authorization constraints take precedence. This Skill is a strategy and invariant layer, not a mandatory long checklist. If another Family clearly owns the next gap and that sibling Skill is installed, route to it rather than duplicating its method here.

Activate for material evidence depth, frame uncertainty, multi-source verification, causal/systemic uncertainty, competing explanations, or an explicit Deep/Max/Ultra research request.

## Progressive references
- [`inquiry-and-research`](references/inquiry-and-research.md) — Load only when the active gap matches one of: deep-research, evidence-need, research-loop, frame-discovery.
- [`evidence-and-provenance`](references/evidence-and-provenance.md) — Load only when the active gap matches one of: evidence, provenance, citation, source-independence.
- [`retrieval-and-observation`](references/retrieval-and-observation.md) — Load only when the active gap matches one of: retrieval, orientation-retrieval, evidence-retrieval, observation.
- [`time-scenarios-and-forecasting`](references/time-scenarios-and-forecasting.md) — Load only when the active gap matches one of: forecast, time, scenario, freshness, volatility.
- [`multimodal-and-data`](references/multimodal-and-data.md) — Load only when the active gap matches one of: multimodal, data, files, images.

- [`ultra-research`](references/ultra-research.md) — Load only for explicit Ultra depth or gaps involving fresh-frame, evidence-ecology, missingness, boundary, research-path reset, or pivotal-claim coverage.

## Modular boundary

Return findings, decisions, evidence, uncertainty, and state effects to the parent task. Do not treat agreement between sibling Skills or agents as independent empirical evidence.
