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 12d 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.

What it actually says

Web Researcher

Multi-source research agent with structured synthesis.

When to Use

  • User asks to research a topic, company, person, or technology
  • User needs competitive analysis or market research
  • User wants fact-checking or source verification
  • User needs summarized information from multiple web sources

Procedure

  1. Parse the research query to identify key topics and constraints
  2. Generate 3-5 diverse search queries covering different angles
  3. Execute searches in parallel using available search tools
  4. For each promising result, extract the full page content
  5. Cross-reference facts across multiple sources
  6. Synthesize findings into a structured report with citations
  7. Flag any conflicting information between sources

Research Output Format

# Research: [Topic]

## Key Findings
- Finding 1 (Source: [url])
- Finding 2 (Source: [url])

## Detailed Analysis
[Structured analysis with inline citations]

## Sources
1. [Title](url) - Relevance: High/Medium/Low
2. [Title](url) - Relevance: High/Medium/Low

## Confidence & Gaps
- Confidence: High/Medium/Low
- Information gaps: [what couldn't be verified]

Pitfalls

  • Always cite sources — never present research without attribution
  • Cross-reference claims across at least 2 sources
  • Note when information is from a single source only
  • Be explicit about information freshness and publication dates
  • Distinguish between facts, analysis, and speculation

Verification

  • Every claim should have at least one source URL
  • Key facts should be cross-referenced across sources
  • Report should explicitly state confidence level
Changes

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.
