vs-crawler

vs-crawler is a skill for Claude Code, Codex from volcengine/SearchCLI. It costs 57 tokens per session (3,728 once invoked), scanned A, original, Apache-2.0.

A website crawler that collects articles, papers, GitHub content, documentation, or RSS entries into JSONL, a format with one JSON record per line. It can then create a searchable collection in Viking AI Search and keep it updated.

In plain words
What is it for?
Use it to build searchable knowledge bases from websites, news, blogs, academic papers, repositories, product documents, or RSS feeds, either once or on a schedule.
Why use it?
It removes the need to manually gather online content and prepare it in a consistent format for search.

About the project

SearchCLI is a command-line interface for connecting agent or business systems to Volcengine’s search, recommendation, and conversational-retrieval services. It is for developers who need to onboard data, build and test retrieval workflows, adjust search strategies, inspect poor results, and verify changes. Its catalogue entries provide installable skills for operating these workflows.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
  • medium Rogue Agent · line 142
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vs-crawler scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Viking Content Crawler

When to Use

Use this skill when the user wants to crawl content from websites and import it into Viking AI Search to build a searchable knowledge base. This covers news sites, blogs, academic papers, GitHub repositories, product documentation, RSS feeds, and similar web content sources.

The agent writes crawler code tailored to the target sites, outputs data in a fixed JSONL schema, and then hands off to the vs-item-onboarding skill for dataset creation and import.

Do not use this skill when:

  • The user already has a local file ready to import (use vs-item-onboarding directly).
  • The user wants to import from a database (use vs-item-onboarding directly with MySQL).

Version Check

Before starting this skill workflow, run vs version check --json. Continue only when status is up-to-date. If status is update-available, stop and tell the user to update the cloned vs repository, then run git pull --ff-only, bash ./scripts/install.sh, and bash ./scripts/install-skills.sh all --target auto --force (PowerShell: scripts/install.ps1 and scripts/install-skills.ps1). If the status is unknown, stop and report that the CLI version could not be verified.

Fixed Schema

All crawled records MUST conform to this schema. Every record is a flat JSON object written as one line in a JSONL file.

Field Type Required Description
id string yes Unique identifier. Use a source-native stable ID (e.g., arXiv ID, GitHub owner/repo, post slug) when available; otherwise derive a deterministic ID from title + author + published_at. Must be deterministic so re-crawling the same item produces the same ID.
title string yes Content title (headline, post title, paper title, repo name, doc page title).
summary string yes Short abstract or description (100-500 characters recommended).
content string yes Full text body with HTML stripped to plain text. For GitHub repos, concatenate README content. For PDF/DOC documents, extract the text content directly into this field.
category string yes One of: news, blog, paper, github, docs, other.
source string yes Human-readable source name, e.g. "Hacker News", "arXiv", "Viking Docs".
author string no Author name(s); multiple authors separated by commas.
published_at string no ISO 8601 datetime, e.g. "2026-07-16T10:30:00Z". Use crawl time if unavailable.
tags array<string> no Tags, keywords, or topics.
language string no ISO 639-1 code: "en", "zh", etc.
source_url string no Canonical URL of the source page (the URL the record was crawled from). Must be a fully-qualified URL with scheme and host.
metadata object no Structured key-value data. Must be flat (one level deep, no nested objects). Values must be scalar (string, number, boolean) — no arrays or objects inside. Only the standard keys listed below are allowed; do not add custom keys. All sources must use the same metadata schema.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vs-crawler is a skill published in the GitHub repository volcengine/SearchCLI (1,189 stars, last pushed 3d ago), licensed Apache-2.0. It adds 57 tokens to every session and 3,728 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
