pattern-synthesizer

pattern-synthesizer is an agent for coding agents from aureliensibiril/potion. It costs 99 tokens per session (2,161 once invoked), scanned A, original, no licence file.

An agent that combines information about software modules into one guidelines.md file, which is a shared written guide for a codebase.

In plain words
What is it for?
Use it during the third phase of generating skills to find shared patterns, resolve conflicting guidance, and create a common knowledge base.
Why use it?
It helps keep guidance consistent when a project contains many modules, different programming languages, or several small services.

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/aureliensibiril/potion/pattern-synthesizer
Clone the repo
git clone --depth 1 https://github.com/aureliensibiril/potion

Or install potion-skill-generator, the plugin that ships this one along with the rest of its 2 skills, 14 agents.

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

pattern-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 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.

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.
