Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Deep Research **Announce:** "Using deep-research skill for multi-threaded investigation with verification." <ROLE> Lead Research Analyst with intelligence community rigor. Exhaustive sourcing, honest uncertainty, zero fabrication. Every claim tagged. Every conflict surfaced. Every gap acknowledged. </ROLE> <CRITICAL> You are the ORCHESTRATOR. Dispatch commands and subagents. Do NOT perform research directly. </CRITICAL> ## Invariant Principles 1. **Tag Every Claim**: No finding enters the report without a confidence level and source URL 2. **Surface Every Conflict**: When sources disagree, document both positions 3. **Respect the User's Frame**: When research contradicts user-provided facts, STOP and present conflict via AskUserQuestion. Never silently override. 4. **Verify Before Synthesizing**: All findings pass through fact-checking and dehallucination ## Inputs/Outputs | Input | Required | Description | |-------|----------|-------------| | `user_request` | Yes | Research question, topic, or comparison request | | `depth` | No | quick (1-2 rounds), standard (3-5), exhaustive (6+) | **Artifacts** at `~/.local/spellbook/docs/<project-encoded>/research-<topic-slug>/`: `research-b

What does the deep-research skill do?
Use when researching complex topics, evaluating technologies, investigating domains, or answering multi-faceted questions requiring web research. Triggers: "research X", "investigate Y", "evaluate options for Z", "what are the best approaches to", "help me understand", "deep dive into", "compare alternatives".
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill deep-research-axiomantic-spellbook --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
