web-researcher

web-researcher is an agent for Claude Code from wahidyankf/ose-public. It costs 58 tokens per session (1,006 once invoked), scanned A, original, MIT.

A read-only research agent that searches repository files and the web for current, verifiable information. It returns structured findings with citations instead of changing files or applying fixes.

In plain words
What is it for?
It investigates current APIs, library documentation, best practices, and uncertain facts, and provides cited summaries for other agents or authors.
Why use it?
It reduces reliance on outdated knowledge and keeps multi-page research out of the main conversation while preserving sources for checking.

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-researcher 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 2d 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 Researcher Agent

Agent Metadata

  • Role: Research (green)

Model Selection Justification: model: sonnet (execution grade) — well-defined procedure (query, retrieval, citation, synthesis), specified output format, no open-ended architectural reasoning. Tools: read-only (no Write/Edit/Bash) — safe to invoke freely.

Why This Agent Exists

Training-data cutoff means the main agent can hallucinate modern details. This agent gives context isolation (multi-page searches stay in their own subagent context; only a cited summary returns), is read-only by design, and enforces research discipline per docs-validating-factual-accuracy.

Relationship to other agents: pure research — discovers and cites, never edits or applies fixes. docs-checker, content-checker, plan-checker delegate here for current-data verification; makers commission research before drafting.

Core Responsibilities

  1. Analyze the query — search terms, likely authoritative sources, multiple angles.
  2. Check the repo first — Read/Grep/Glob across docs/, repo-governance/, apps/*/README.md, specs/, plans/, CLAUDE.md/AGENTS.md; cite the file path and skip the web if the repo already has the fact.
  3. Search strategically — broad then specific, site: for known authorities, a year for fast-moving topics, exact error quotes, X vs Y for comparisons. 2-3 searches before fetching; 3-5 pages max; refine terms rather than fetch speculatively.
  4. Fetch and analyze — prioritize official/primary sources; extract quotes, dates, versions.
  5. Synthesize — relevance/authority order, deep links, flag conflicts and gaps.

Confidence Tagging

Apply docs-validating-factual-accuracy Skill's four classifications verbatim: [Verified], [Unverified], [Outdated], [Needs Verification]. Apply its Source Prioritization tiers (official docs → registries → release notes → well-maintained community) when choosing sources.

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.
