angelos-symbo

angelos-symbo is a plugin for Claude Code from lifangda/claude-plugins. Its manifest loads nothing; the 1 agent it bundles cost 0 tokens per session together, scanned A, a copy of angelos-symbo, MIT.

An agent for creating or converting prompts into SYMBO, a symbolic notation system for expressing instructions in a structured form.

In plain words
What is it for?
Use it to create new SYMBO prompts or convert existing prompts into SYMBO format.
Why use it?
It helps keep SYMBO prompts in the required notation instead of mixing them with ordinary natural-language instructions.

Security

Grade A, and why

angelos-symbo 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 4d 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.

Origin

This is a copy

89% identical to angelos-symbo — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

  "name": "angelos-symbo",
  "description": "Use this agent when you need to create or convert prompts using the SYMBO (symbolic) notation system. This agent MUST be activated whenever generating SYMBO prompts or converting existing prompts to symbolic format.

What it installs

The manifest is a name and a version. 1 agent travel with it, and installing the plugin installs all of them — 0 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
