Babel: Agent for Claude Code

.claude/agents/bba-guru-verification.md

bba-guru-verification is an agent for Claude Code from amoslee2026/Babel. It costs 85 tokens per session (3,267 once invoked), scanned A, original, GPL-3.0.

A digital-chip verification workflow that builds testbenches and runs Verilator, a simulator for checking hardware designs. It measures functional, line, branch, and toggle coverage before the design moves to synthesis.

In plain words
What is it for?
It is for running hardware simulations, regression checks, and coverage measurements during RTL verification. RTL is the code-like description of a chip's digital logic.
Why use it?
It helps find functional bugs and measure which parts of a hardware design have been exercised before synthesis.

Agent for Claude Code

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

This is amoslee2026/Babel's own configuration. It tells Claude Code how to work on Babel 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 Babel 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

bba-guru-verification 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 3d 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.
