t-800-agent: Agent for Claude Code

.cursor/agents/t-800-research-news.md

t-800-research-news is an agent for Claude Code, Cursor from Khar-AG/t-800-agent. It costs 83 tokens per session (432 once invoked), scanned A, original, MIT.

A read-only agent for recent news, release notes, and change announcements from sources such as Hacker News, vendor blogs, and the Cursor changelog. It prefers news from the last 30 days and rejects undated items.

In plain words
What is it for?
Use it during deep research about trends, breaking changes, new AI models, or updates to coding tools; it should not be the only research source.
Why use it?
It adds current context for fast-changing tools and helps distinguish announcements from facts that have been independently checked.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

This is Khar-AG/t-800-agent's own configuration. It tells Claude Code and Cursor how to work on t-800-agent 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 t-800-agent 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

t-800-research-news 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 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.
