ModSearch — скилл

---
name: modsearch
description: "Plug-in web search, X (Twitter) search, and page fetch for models without native web access. Use whenever the task needs current information, external facts, source links, posts from X, or the content of a specific URL, and the active model/harness has no native search or fetch tool. Runs the modsearch CLI to return structured JSON evidence. Also use when the user asks how to install or configure modsearch, or wants to switch engines or add a key."
compatibility: Requires network access and one of node 22+/npx, bun/bunx, or a preinstalled modsearch binary on PATH.
allowed-tools: Bash

# ModSearch — Search & Fetch Bridge Skill

Use this skill when:

- The user asks about anything after your knowledge cutoff (releases, news, prices, versions)
- The answer needs source links or verifiable external facts
- The user asks what people are saying on X or Twitter (推特, 推文, tweets, threads)
- The user gives a URL to read and the harness has no fetch tool
- The user asks how to configure modsearch, add a key, or change engines

Do not use this skill for:

- Analyzing images (that is `modlens`)
- Questions your own knowledge answers reliably and time does not affect
- Searching inside DeepSeek Harness (dsh, `DSH_SHELL=1`): there modsearch runs as
  a plugin behind the native `web_search`. If dsh still answers from its default
  provider, the plugin is missing: point the user to Step 0 of INSTALL.md

## Prerequisites

Run every modsearch command through the launcher bundled with this skill.
Replace `<skill-dir>` with the directory this SKILL.md lives in:

```bash
bash <skill-dir>/scripts/run.sh -q "test"                                       # macOS / Linux
powershell -ExecutionPolicy Bypass -File <skill-dir>\scripts\run.ps1 -q "test"  # Windows
```

The launcher finds a working way to run modsearch and forwards your arguments to it unchanged. It tries, in order: a compatible `modsearch` already on `PATH`, then `npx`, then `bunx`. If none of those exists it prints a JSON diagnosis to stderr and exits 78, with a `nextSteps` list for the user. Relay those steps instead of retrying. To see the full diagnosis, run `bash <skill-dir>/scripts/run.sh doctor --json` (on a machine that can launch the CLI it also chains modsearch's own engine/config `doctor`).

Nothing else needs setting up first: modsearch works with no config file. Web search and page fetch run out of the box on Firecrawl's keyless free quota (no signup, no key), and a configured engine or API key takes precedence when present.

### If you cannot run the launcher script

Some harnesses forbid running scripts. Reason through the same order by hand and run the first line that works (the pinned version is 5.10.9):

1. A `modsearch` on `PATH` whose major version is 5 and is at least 5.10.9: `modsearch <args>`.
2. Otherwise, if `npx` exists: `npx --yes --package @liustack/modsearch@5.10.9 modsearch <args>`.
