claude-control: Skill for Claude Code

.claude/skills/web-research/SKILL.md

web-research is a skill for Claude Code from dewil/claude-control. It costs 189 tokens per session (1,578 once invoked), scanned A, original, MIT.

A web-research workflow for answering questions with current, checked information from multiple online sources. It breaks the question into searches, reads full pages, compares claims and records citations with URLs and access dates.

In plain words
What is it for?
Use it for current facts, comparisons, open research, or checking whether a claim is true. It is intended for research that needs several sources and citations, rather than a quick fact from one known page.
Why use it?
It reduces the risk of relying on outdated search snippets or a single unverified source. It makes important claims traceable and highlights uncertainty or information that may have changed.

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

web-research 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 2mo 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.

web-research

Скилл задает дисциплину поиска в интернете. Дефолтное поведение модели - дернуть WebSearch один раз, прочитать сниппеты и ответить - дает поверхностный и часто устаревший/галлюцинированный результат. Здесь поиск превращается в проверяемый процесс: несколько переформулированных запросов, чтение страниц целиком, перекрестная сверка фактов между источниками, явная пометка неуверенного и устаревшего, обязательные цитаты.

Ценность не в количестве ссылок, а в том, что каждое утверждение в ответе привязано к источнику и пережило попытку его опровергнуть.

Когда применять

  • Нужен фактический ответ из веба, который мог измениться после обучения модели: версии, цены, релизы, статус проекта, события, "что сейчас с X".
  • Сравнение вариантов (инструменты, библиотеки, подходы) с опорой на актуальные данные.
  • Проверка конкретного утверждения ("правда ли, что Y") - найти подтверждающие и опровергающие источники.
  • Открытый research по теме, где нужен синтез из нескольких источников.

Когда НЕ применять

  • Один быстрый факт с известным URL или из одной страницы - прямой WebFetch/WebSearch без обвязки.
  • Вопрос уверенно отвечается из знаний модели и свежесть не важна (определения, устоявшаяся теория, синтаксис языка) - не ходить в веб ради проформы.
  • Запрос про код/файлы текущего репозитория - это searcher/explorer, не веб.

Жесткие правила

  1. Минимум два независимых источника на ключевое утверждение. Один источник = гипотеза, не факт. Если второго нет - так и пометить ("по единственному источнику").
  2. Читать страницы, а не сниппеты. По релевантным результатам поиска делать WebFetch и опираться на полный текст. Сниппет выдачи - повод открыть страницу, а не готовый факт.
  3. Каждый факт - с источником. В заметке у утверждения стоит ссылка (URL) и дата доступа. Без источника утверждение в ответ не идет.
  4. Свежесть явно. Для меняющихся данных (цены, версии, статусы) указывать дату публикации источника и помечать риск устаревания. Сегодняшнюю дату брать из контекста сессии.
  5. Противоречия не сглаживать. Если источники расходятся - показать расхождение и какой источник почему весомее (первоисточник > агрегатор > форум), а не выбирать удобный молча.
  6. Не выдавать знания модели за результат поиска. Если факт не подтвержден найденной страницей - он либо помечен как догадка, либо не включается.

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.
