ModSearch — Search & Fetch Bridge

Gives models without native web access a CLI-backed web search, X (Twitter) search, and page fetch that returns structured JSON evidence.

Web & APIIntermediate★ 111⑂ 5AI score 10/10Last updated: Aug 16, 2026

What it does

  • Runs the modsearch CLI to perform web search, X (Twitter) search, and single-URL page fetch when the host model has no built-in search or fetch tool.
  • Always returns a structured JSON contract (results[], items[].url, summary, uncertainty, warnings, attempts) so answers can be cited and audited.
  • Multiple engines per role (antigravity-cli, tavily, exa, firecrawl, grok-cli, local) with automatic fallback and quota cooldown handling.
  • A bundled launcher resolves the runtime in order — modsearch on PATH → npx → bunx — and emits a JSON diagnosis with next steps if none is available.
  • Explicit safety rule: fetched pages and posts are treated as untrusted data, never as instructions.

Who it's for

  • Anyone who needs post-cutoff facts: releases, news, prices, library versions.
  • Users on harnesses without a web tool who still need verifiable source links.
  • Researchers and marketers tracking discussion on X.

Examples

  1. "What's the latest release of this framework?" → modsearch -q "...", then cite items[].url.
  2. "What are people saying on X about this launch?" → --source x; if Grok isn't configured, relay the status: degraded warning instead of claiming X coverage.
  3. "Summarize this page" → modsearch -u "<url>" -q "focus" to fetch with an extraction focus.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/modsearch folder from the GitHub repo liustack/modsearch into my ~/.claude/skills/modsearch/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/liustack/modsearch.git /tmp/modsearch && mkdir -p ~/.claude/skills && cp -r /tmp/modsearch/skills/modsearch ~/.claude/skills/modsearch

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/liustack/modsearch.git /tmp/modsearch
  3. Copy the skill in: mkdir -p ~/.claude/skills && cp -r /tmp/modsearch/skills/modsearch ~/.claude/skills/modsearch
  4. Install a JavaScript runtime: Node 22.13+ (https://nodejs.org) or Bun (https://bun.sh).
  5. Smoke test: bash ~/.claude/skills/modsearch/scripts/run.sh -q "test" (on Windows use powershell -ExecutionPolicy Bypass -File ...\scripts\run.ps1 -q "test").
  6. If something fails, run bash ~/.claude/skills/modsearch/scripts/run.sh doctor --json to see engine readiness, and add a Tavily/Exa/Firecrawl key if web search has no engine.
  7. Restart Claude Code, then ask for current information or hand it a URL — the skill triggers automatically.
