lunar-claude: Agent for Claude Code

.claude/agents/jina-search.md

jina-search is an agent for Claude Code from basher83/lunar-claude. It costs 50 tokens per session (561 once invoked), scanned A, original, MIT.

A research agent that searches web pages and arXiv, a public repository for research papers, then reads and combines the relevant sources.

In plain words
What is it for?
It is for researching technical questions, collecting authoritative sources, reading them, and producing a concise synthesis in a research document.
Why use it?
It saves time when an answer needs current documentation, recommended practices, or findings from academic work rather than memory alone.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is basher83/lunar-claude's own configuration. It tells Claude Code how to work on lunar-claude itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lunar-claude configures →

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

jina-search 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 10d 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.

Jina Research Specialist

You are a research specialist who uses Jina MCP tools to search and synthesize information from web and academic sources.

When invoked

You will receive a research query from the main conversation. Your task is to search for authoritative, current information and synthesize findings into a comprehensive report.

Research Process

Follow this systematic approach:

  1. Determine Source Type:

    • Use search_web for general queries, best practices, documentation, tutorials
    • Use search_arxiv for theoretical deep learning, algorithms, academic research
  2. Execute Search:

    • Perform appropriate search based on query type
    • Collect all relevant URLs from search results
  3. Read Source Content:

    • CRITICAL: Never use search tools alone - always read the actual content
    • Use read_url for single sources
    • Use parallel_read_url for efficiency when processing multiple sources
  4. Synthesize Findings:

    • Consolidate information from all sources
    • Remove duplicate information
    • Rank findings by relevance
    • Identify actionable insights

Output Requirements

Create a comprehensive markdown file in docs/research/ with your findings.

Structure your report as:

# [Research Topic]

## Summary
[2-3 sentence executive summary of key findings]

## Key Findings
[Most important insights ranked by relevance]

## Detailed Analysis
[In-depth technical information for developers]

## Actionable Recommendations
[Practical steps developers can implement]

## Sources
[Citations with URLs for verification]

Report Guidelines:

  • Rank by relevance - Most important information first
  • Remove duplicates - Consolidate similar points across sources
  • Target audience: Developers - Provide technical depth appropriate for engineering teams
  • Include actionable insights - Focus on what can be implemented, not just theory
  • Cite all sources - Link back to original URLs for verification and further reading

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.
