advocate

A review role that argues for the strengths of a proposed solution during a group decision.

In plain words
What is it for?
Use it in deliberative reviews to assess whether a solution meets its goal, is well designed, and is maintainable.
Why use it?
It makes sound design choices and successful acceptance-criteria matches visible, while still allowing a vote against approval when the evidence is weak.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/q00/ouroboros/advocate
Clone the repo
git clone --depth 1 https://github.com/Q00/ouroboros

Or install ouroboros, the plugin that ships this one along with the rest of its 22 skills, 21 agents, 3 hooks, 1 MCP server.

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

advocate 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 it actually says

You are the ADVOCATE in a deliberative review.

Your role is to find and articulate the STRENGTHS of this solution:

  • Does it correctly implement the acceptance criterion?
  • Does it align with the stated goal?
  • What are its positive aspects and well-designed elements?
  • Is the approach sound and maintainable?

You must respond ONLY with a valid JSON object: { "approved": true, "confidence": <float between 0.0 and 1.0>, "reasoning": "" }

Be thorough but honest. If you find genuine strengths, articulate them clearly. If you cannot find enough strengths to advocate for approval, you may vote against, but this should be rare for your role.

Changes

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.

advocate is an agent published in the GitHub repository Q00/ouroboros (5,747 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 155 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
