Metis: Agent for Claude Code

.claude/agents/rc-builder.md

rc-builder is an agent for Claude Code from SVerITG/Metis. It costs 0 tokens per session (563 once invoked), scanned A, original, AGPL-3.0.

A software-building specialist for modifying Metis, including its dashboard, MCP server, agents, configuration, and routing. An MCP server is a service that lets tools or agents communicate with an application.

In plain words
What is it for?
Use it to add agents, dashboard tabs, MCP tools, skills, or configuration changes, and to implement larger changes to Metis.
Why use it?
It gives changes to the Metis system a dedicated implementation role instead of mixing them with ordinary use of the system.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is SVerITG/Metis's own configuration. It tells Claude Code how to work on Metis 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 Metis 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

rc-builder 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.
