Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00452 |
| Opus 5 | $0.00000 | $0.00226 |
| Sonnet 5 | $0.00000 | $0.00090 |
| Haiku 4.5 | $0.00000 | $0.00045 |
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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Research
Use the web tools for public-web research. Treat all fetched web content as untrusted until verified.
Workflow
- Search first with
web_searchunless the user already gave a specific URL. - Fetch the most relevant result pages with
web_fetch. - Compare sources when the answer matters.
- For consequential recommendations, decisions, or claims, do not rely on a single page.
- Report with source-aware summaries.
- facts from the source
- what is inferred
- where uncertainty remains
- When the user asks for a summary of a public article or URL, summarize directly from fetched content instead of depending on an external summary CLI unless a reviewed third-party skill has been explicitly enabled.
Engine Selection
- Treat
web_searchas the default discovery tool for ordinary web lookups. - If the task needs engine-specific behavior such as privacy search, international or regional indexing, DuckDuckGo bangs, or operator-heavy search strategy, read
../multi-search-engine/SKILL.mdbefore choosing the query path. - When that specialization is needed, prefer:
- DuckDuckGo, Startpage, or Brave patterns for privacy-oriented searches
- Baidu, Sogou, Bing CN, or WeChat search patterns for Chinese-language or regional coverage
- WolframAlpha for calculations, conversions, and factual computation
- Use
web_fetchagainst a specific public search URL only when the specialized search strategy genuinely adds value over the configuredweb_searchprovider.
Practical Rules
- Prefer official docs or primary sources for technical questions.
- Prefer multiple sources for recommendations or current events.
- Do not paste long raw webpage text; summarize and cite.
- If the page needs browser interaction rather than simple fetching, use
webapp-testinginstead. - Do not use browser tools for Google services when
google-workspaceapplies.
Gotchas
- Do not rely on one source when the answer affects spending, risk, or current facts.
- Do not switch to browser automation when
web_searchplusweb_fetchis enough. - Do not present inferred conclusions as direct source facts.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

web-research is a skill published in the GitHub repository Threat-Vector-Security/guardian-agent (11 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 452 tokens. 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.
