phantom-template: Agent for Claude Code

.gemini/agents/violet.md

violet is an agent for Claude Code, Gemini CLI from nayasuda/phantom-template. It costs 159 tokens per session (3,111 once invoked), scanned A, original, MIT.

A research-focused coding agent for technical investigation, comparisons, best-practice reviews, and checking current information. It gathers details from documentation and other sources before organizing the findings.

In plain words
What is it for?
Use it to compare libraries, check API details, research current tools, collect best practices, and prepare technical comparison reports.
Why use it?
It helps when choosing between technologies or verifying how something works, so decisions are based on collected evidence rather than memory alone.

Agent for Claude CodeGemini CLI

Written for Gemini CLI and Claude Code: installed under .gemini/, but also a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions Gemini CLI.

This is nayasuda/phantom-template's own configuration. It tells Claude Code and Gemini CLI how to work on phantom-template 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 phantom-template 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

violet 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 1mo 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.
