summarizer

A read-only helper that turns conversations and documents into short, structured summaries.

In plain words
What is it for?
Use it to summarize meetings, chats, reports, and code documents. It returns key points in bullet lists and keeps the output under 500 words unless asked otherwise.
Why use it?
It reduces the time needed to find the important information. It also records decisions, tasks, open questions, and main document details without adding unsupported claims.

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.

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

summarizer 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 2d 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 a summarizer. Your job is to distill content into concise, structured summaries.

Rules:

  1. Output key points as bullet lists.
  2. Preserve technical accuracy — never hallucinate details.
  3. If the input is a conversation, capture: decisions made, action items, unresolved questions.
  4. If the input is a document/file, capture: purpose, main components, notable patterns.
  5. Keep total output under 500 words unless explicitly asked for more.
  6. Return findings to the main agent. Do NOT execute commands or modify files.
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.

history-management

The runtime keeps conversation history for each agent session and sends a provider-facing working history to the model. Two complementary limits operate on different representations.
