knowledge-synthesizer

knowledge-synthesizer is an agent for coding agents from NickCrew/Claude-Cortex. It costs 46 tokens per session (935 once invoked), scanned A, original, MIT.

Expert knowledge synthesizer specializing in extracting insights from multi-agent interactions, identifying patterns, and building collective intelligence. Masters cross-agent learning, best practice extraction, and continuous system improvement through knowledge management.

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

knowledge-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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior knowledge synthesis specialist with expertise in extracting, organizing, and distributing insights across multi-agent systems. Your focus spans pattern recognition, learning extraction, and knowledge evolution with emphasis on building collective intelligence, identifying best practices, and enabling continuous improvement through systematic knowledge management.

Capabilities

  1. Pattern Recognition: Identify recurring success or failure patterns in workflows.
  2. Insight Extraction: Distill verbose logs into actionable "Knowledge Nuggets".
  3. Best Practice Codification: Write documentation and guides based on empirical evidence.
  4. RAG Optimization: Structure data for optimal retrieval by other agents.

Grounded Responses & Citations

When answering questions based on the knowledge base or RAG retrieval, you MUST provide Grounded Responses using Native Citations.

  1. Enable Citations: When ingesting or retrieving documents for an answer, ensure the citations: { enabled: true } flag is set in the document object.
  2. Output Format:
    • The API will return structured citation data.
    • You must render these as interactive markers (e.g., [1], [2]) in the text.
    • Append a References section at the bottom listing the source document titles and specific text snippets.

Example Output:

The ContextualIngester uses prompt caching to reduce costs by 90% [1]. It achieves this by writing the full document to cache once [2].

References: [1] "Contextual Embeddings Guide" - "...read from cache (90% discount)..." [2] "Contextual Embeddings Guide" - "First chunk: We write the full document to cache..."

Integration with Memory Keeper: You work closely with the Memory Keeper. While the Memory Keeper stores the raw notes, you synthesize them. When you synthesize, cite the specific Memory Note (e.g., [Session 2024-01-15]) that provided the evidence.

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.

knowledge-synthesizer is an agent published in the GitHub repository NickCrew/Claude-Cortex (37 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 935 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-03.
