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 | $0.01586 | $0.01586 |
| Opus 5 | $0.00793 | $0.00793 |
| Sonnet 5 | $0.00317 | $0.00317 |
| Haiku 4.5 | $0.00159 | $0.00159 |
Grade A, and why
jina 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 5d 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Jina MCP Tools Usage Rules
Always Use Jina MCP Tools for Research and Verification
When you are uncertain about knowledge, or the user doubts your answer, always use Jina MCP tools to search and read best practices and latest information.
Why Use Jina MCP Tools
- Up-to-date information: Access current web content and academic papers
- Comprehensive search: Search web, academic papers (arXiv), and images
- Efficient reading: Parallel reading capabilities for multiple sources
- Quality sources: Access academic papers and verified web content
- Deduplication: Built-in tools to remove duplicate content
Available Jina MCP Tools
Search Tools
mcp_jina-mcp-server_search_web- Search the web for current information, news, articlesmcp_jina-mcp-server_search_arxiv- Search academic papers and preprints on arXivmcp_jina-mcp-server_search_images- Search for images across the webmcp_jina-mcp-server_parallel_search_web- Run multiple web searches in parallelmcp_jina-mcp-server_parallel_search_arxiv- Run multiple arXiv searches in parallelmcp_jina-mcp-server_expand_query- Expand and rewrite search queries for better results
Reading Tools
mcp_jina-mcp-server_read_url- Extract and convert web page content to markdownmcp_jina-mcp-server_parallel_read_url- Read multiple web pages in parallelmcp_jina-mcp-server_capture_screenshot_url- Capture screenshots of web pagesmcp_jina-mcp-server_guess_datetime_url- Guess last updated/published datetime
Utility Tools

Critical Rule: Search Must Be Complemented with Read
NEVER use search tools alone. Every search must be complemented with read_url or parallel_read_url to read the
source URL content.
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.
- 5d ago First seen · 179 lines · 1,586 tokens per session scan A c9859cece5a3
jina is a cursor rule published in the GitHub repository basher83/lunar-claude (22 stars, last pushed yesterday), licensed MIT. It adds 1,586 tokens to every session, about $0.0079 per session on Opus 5. 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.
