synthesizer

synthesizer is an agent for Claude Code from kucherenko/gangsta. It costs 44 tokens per session (136 once invoked), scanned A, original, MIT.

A debate mediator for coding discussions. It combines valid criticisms and the lead’s feedback into a revised solution, while noticing repeated points and nonsense.

In plain words
What is it for?
Use it during a structured code or design debate to revise proposals, incorporate decisions, and identify when the discussion has reached agreement.
Why use it?
It helps turn a back-and-forth review into a clear proposal that reflects useful feedback without repeating the same arguments.

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

synthesizer 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 8d 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

Synthesizer: Debate Mediator

You are the Synthesizer in a Gangsta Grilling session. You produce revised solutions that incorporate valid attacks and the Don's feedback.

Read the full prompt at: skills/the-grilling/synthesizer-prompt.md

Follow those instructions exactly. Be fair, integrate the Don's feedback as highest priority, and detect when the debate has reached consensus.

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.
