deep-research

Disciplined, multi-source meta-research for high-stakes questions — the heavyweight alternative to the fast research router. Runs a 9-phase pipeline (reframe into falsifiable hypotheses → genre/blocks → plan → capability discovery → parallel sub-agent fan-out → score & triangulate → synthesize + adversarial pass → verify → refresh targets), triangulates every thesis against >=3 independent, differently-typed sources, saves each source to its own file with verbatim quotes, and never fabricates a citation. Output is an auditable, reusable folder with a delta-update refresh protocol. Use when a wrong answer is expensive: strategy, comparing N options, hypothesis validation, mapping a field.

cs-deep-research

/cs-deep-research

/cs:deep-research <question> — Disciplined multi-source investigation for a high-stakes question. Reframes into falsifiable hypotheses, plans, fans out parallel search sub-agents, triangulates every thesis against >=3 independent sources, saves each source to its own file with verbatim quotes, runs an adversarial pass, and emits an auditable, reusable research folder with a refresh protocol. The heavyweight alternative to the fast research router.

Agents1

cs-deep-research

/cs-deep-research

Rigor-first meta-research persona for high-stakes questions. Reframes the question into 2-4 falsifiable hypotheses, writes a plan, discovers available channels/APIs, fans out parallel search sub-agents, triangulates every thesis against >=3 independent differently-typed sources, saves each source to its own file with verbatim quotes, runs a mandatory adversarial pass, and emits an auditable, reusable research folder with a refresh protocol. Refuses to fabricate citations (empty fetch = empty claim). Refuses to state a claim backed by fewer than 3 independent sources as fact. Refuses to skip the adversarial pass on medium/deep investigations. Refuses to run sub-agents sequentially.

Skills1

deep-research

/deep-research

Run a disciplined, multi-source research investigation for a high-stakes question or decision — fan-out web search across many channels, parallel sub-agents, source triangulation (each claim backed by ≥3 independent sources), an adversarial review pass, and every source saved to its own file with verbatim quotes for reuse. Use when a low-quality answer is expensive: strategy work, comparing N products/methods/markets, validating a hypothesis with external data, or mapping how a field works. NOT for quick fact-checks (answer directly), structured 12-dimension competitor scoring (use competitive-teardown), or fast topic overviews where the decision risk is low (use the research router instead).

Works with: Claude Code · OpenAI Codex · Gemini CLI · OpenClaw · Hermes Agent¹ · Mistral Vibe² · Cursor · Aider · Windsurf · Kilo Code · OpenCode · Augment · Antigravity

5,200+ GitHub stars — the most comprehensive open-source Claude Code skills & agent plugins library.

What Are Claude Code Skills & Agent Plugins?

Claude Code skills (also called agent skills or coding agent plugins) are modular instruction packages that give AI coding agents domain expertise they don't have out of the box. Each skill includes:

SKILL.md — structured instructions, workflows, and decision frameworks
Python tools — 593 CLI scripts (all stdlib-only, zero pip installs)
Reference docs — 711 templates, checklists, and domain-specific knowledge files

One repo, thirteen platforms. Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, Hermes Agent skills, Mistral Vibe skills, and converts to more tools via scripts/convert.sh. All 593 Python tools run anywhere Python runs.

Skills vs Agents vs Personas

	Skills	Agents	Personas
Purpose	How to execute a task	What task to do	Who is thinking
Scope	Single domain	Single domain	Cross-domain
Voice	Neutral	Professional	Personality-driven
Example	"Follow these steps for SEO"	"Run a security audit"	"Think like a startup CTO"

All three work together. See Orchestration for how to combine them.

Quick Install

Gemini CLI (New)

# Clone the repository
git clone https://github.com/alirezarezvani/claude-skills.git
cd claude-skills

# Run the setup script
./scripts/gemini-install.sh

# Start using skills
> activate_skill(name="senior-architect")

Claude Code (Recommended)

# Add the marketplace
/plugin marketplace add alirezarezvani/claude-skills

Hermes Agent is BYO-sync tier: the repo ships a pre-generated .hermes/skills/claude-skills/ tree, but you run python scripts/sync-hermes-skills.py once locally to install into ~/.hermes/skills/. Uses the same agentskills.io SKILL.md standard — no format conversion. ↩
Mistral Vibe is also BYO-sync tier: the repo ships a pre-generated .vibe/skills/claude-skills/ tree, run ./scripts/vibe-install.sh once locally to install into ~/.vibe/skills/. Same agentskills.io SKILL.md standard — no format conversion. Docs: https://docs.mistral.ai/mistral-vibe/agents-skills. ↩
