From d90de0759cf346599e86cd39c21cdc678bc4fbd2 Mon Sep 17 00:00:00 2001 From: dtoro Date: Mon, 6 Jul 2026 18:32:08 +0200 Subject: [PATCH] docs: redesign README for agent clarity and usability MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: README.md was human-centric and lacked critical context for agents (LLMs running on enrolled homelab clients). Agents needed: - Explicit entry points (AGENTS.md → OIKOS.md → skills → MCP/files) - Decision tree for tool selection (when to use MCP vs files vs grep) - Explanation of operating model (OODA loop, risk classes, layer model) Solution: Reorganized README with agent-first sections while preserving existing human-useful content: NEW SECTIONS: - "For Agents" (entry points + MCP tool selection table with decision criteria) - "Understanding the Operating Model" (Mermaid OODA loop diagram, risk classes, decision flow: classify → escalate if needed → execute → document) - "Finding & Understanding Information" (layer model table: sources/wiki/index/log, what's immutable vs editable, when to update docs) REVISED SECTIONS: - "Map & Quick Navigation" (agent entry points first, then topology) - "Conventions" (expanded with agent-specific guidance: caveman.md, page-templates.md) - "Updating the Wiki" (clarified infrastructure changes vs restructuring; reinforced same-session update rule with explicit checklist) - "More Information" (grouped agent-facing resources: HERMES, operations, skills, shared conventions) All links verified. No new files needed — all referenced content already exists. Verification: - OODA loop diagram present (visual roadmap for decision flow) - MCP vs Files vs Shell table shows decision criteria - Layer model (sources/wiki/index/log) explained with immutability matrix - All cross-references resolve - Existing topology + infrastructure content preserved Co-Authored-By: Claude Opus 4.8 --- README.md | 273 +++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 217 insertions(+), 56 deletions(-) diff --git a/README.md b/README.md index 9bd425b..7428f18 100644 --- a/README.md +++ b/README.md @@ -1,89 +1,250 @@ # Homelab Wiki — `hubris` -Living documentation for the **hubris** Proxmox homelab.
