Anti-hallucination toggle for Claude Code. Activates three constraints from Anthropic's documentation that force Claude to cite sources, say "I don't know" when unsure, and ground responses in direct quotes.
Works in Claude Code CLI, the macOS desktop app, and the VS Code extension. Open Claude Code and run these two commands:
Step 1 -- Add the marketplace:
/plugin marketplace add assafkip/research-mode
Step 2 -- Install the plugin:
/plugin install research-mode@assafkip-research-mode
That's it. To confirm it installed, run /plugin and check that research-mode appears in your list.
Alternative -- install as a standalone skill:
If you prefer not to use the plugin system, clone this repo and copy the SKILL.md file into your project's .claude/skills/research-mode/ directory.
/research-mode:research
Or with a topic:
/research-mode:research what caused the Change Healthcare breach
Say "exit research mode" to turn it off.
Three constraints activate simultaneously:
- Say "I don't know" -- no guessing, no inferring. If there's no credible source, Claude says so.
- Cite everything -- every claim must reference a file, URL, paper, or named source. Unsourced claims get retracted.
- Quote first, then analyze -- responses are grounded in word-for-word quotes from source material, not paraphrased summaries.
- Not always-on. It's a toggle. Turn it on for research, off for creative work.
- Not slow. Claude still uses tools in parallel and works efficiently.
- Not restrictive on new ideas. You can synthesize across sources, but inputs must be grounded.
LLMs hallucinate. When you're doing research that matters, you need guardrails that force citation discipline. This plugin packages Anthropic's own recommendations into a one-command toggle.
"Plugin not found" after Step 1: Make sure you typed the marketplace command exactly as shown. The marketplace name is assafkip/research-mode (GitHub username/repo).
Command doesn't appear after install: Run /reload-plugins to refresh, or restart Claude Code.
Want to scope it to one project only: Add --scope project to the install command in Step 2.
Assaf Kipnis -- built while running GTM, investor outreach, and content ops for KTLYST entirely through Claude Code. When your AI assistant is writing your pitch decks, researching competitors, and drafting investor briefs, hallucinated facts aren't a minor annoyance. They're a credibility risk. This toggle exists because I needed it.
