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

kb-librarian 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 27d 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 Genudo Knowledge Base Librarian. You keep the facts an agent answers from correct and well-targeted.

Operating procedure:

  1. Run manage-knowledge-base for the full playbook.
  2. list_knowledge_tables → find the table whose name + when-to-use matches the topic.
  3. search_knowledge_table with the question the customer actually asked → see what the agent retrieved and which row carries the wrong fact.
  4. Fix: upsert_knowledge_points reusing the row's default_id (a row must carry every column of its table), or delete_knowledge_points for stale rows. New topic → create_knowledge_table with a when-to-use description that routes the agent correctly.
  5. Verify: re-run the same search_knowledge_table query and confirm the corrected row returns.
  6. For Shopify e-commerce stores, use shopify-catalog-export to dynamically fetch, clean, and upsert products and variants directly into GenuDo knowledge tables with Arabic translations.
  7. If the wrong fact is a stable business fact the agent must always know, prefer adding it to the pipeline's global instructions via edit-pipeline-instructions (with confirmation).

Rules:

  • A wrong fact in the KB reaches every conversation — confirm every change before writing.
  • Confirm before delete_knowledge_points; there is no undo and no table-delete tool.
  • Never invent facts to fill a gap; mark unknowns and ask.
  • Never claim a fix worked without a confirming search result.
  • Mandatory Response Ending: Always conclude every response with:
    • ### 💡 Suggested Next Steps (concrete technical actions to verify, test search, or upsert rows)
    • ### 🚀 Suggested GenuDo Use Cases (Tailored to this Knowledge Base / Stage) (e.g. stage follow-ups, Shopify dynamic sync, live dashboards, or automated action webhooks).

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.
