Core Knowledge Base Hub — Company Memory & Recall
When Not to Use
Simple or one-off tasks — if the task is straightforward, direct execution is faster than structured methodology.
Already established workflows — follow existing team conventions rather than introducing new frameworks.
When automation overhead exceeds benefit — for very small scopes, the setup cost may not be justified.
Dependencies
Python 3.8+ or Node.js 18+
Access to relevant APIs/services for your specific use case
Basic understanding of the domain concepts

Money-Making Overview
A well-structured knowledge base is the single highest-leverage investment for an autonomous agent ecosystem. Every hour spent organizing knowledge saves 10 hours of re-discovery and context-switching. Direct revenue impact:
Capability
ROI Impact
Timeline
Session-start context loading
Eliminates 10-15 min of re-orientation per session
Day 1
Company knowledge recall
Instant access to strategies, playbooks, finance data
Total addressable value: A mature knowledge base turns a 1-person operation into a 10-person operation by eliminating context loss. Every lost context costs $50-200 in re-discovery time. With 5+ sessions per day, that's $250-1,000/day saved.
Phase 1: Initialize Knowledge Base Structure (10 min)
# 1. Verify PARA directory structure existsls -la ~/kb/projects/

kb read --today
# Expected: daily note with yesterday's summary, current tasks, open decisions# 3. Quick scan of company entities

company-kb list-entities --type product

Anti-Rationalization Table
Rationalization
Reality
"I'll remember what we decided last week"
You won't. Neither will the next agent. Write it down or lose it.
"The conversation is the memory"
Conversations disappear when the session ends. KB persists.
"Structuring by PARA is overkill for one person"
PARA scales from 1 to 100 agents. Start structured or refactor later at 10x cost.
"I'll add facts later when I have time"
"Later" never comes. Capture at the moment of decision.
"Search is good enough for retrieval"
Search finds strings. Structure finds meaning, decisions, and relationships.
"Archiving loses information"
Archiving moves stale data out of active context — it is not deletion.
"Only humans need documentation"
Agents need documentation more than humans — they have no intuition to fill gaps.
Output Format
When using the knowledge base hub, produce structured recall results:
{"query":"pricing decision","results":[{"file":"areas/pricing-strategy/facts.yaml","relevance_score":85.0,"snippet":"Decision: Standard tier at $49/mo, Pro tier at $99/mo","last_updated":"2026-07-01T14:30:00Z","status":"confirmed"}],"total_found":3,"total_returned":2,"filters_applied":{"category":"areas"}}
