Handbooks

Instance-agnostic reference material for coding agents — the verbose, citable kind that belongs in a retrieval store, not in a skill.

What goes here

• Public standards, style guides, and conventions that apply regardless of which box or project is running — general git operations, language style guides, CERT/MISRA-style rulebooks.
• Long-form and specific. A handbook can be as detailed as it needs to be; nothing here is loaded into a model's context wholesale, so length carries no per-turn tax.

What does not go here

• Anything specific to one machine or one project. A local Gitea's branch-naming rule, this box's PR checklist — that's instance-bound and belongs in that project's own KB corpus instead (kb-engineering for halogen).
• Short, prescriptive procedures achievable within a context window or two. That's a skill, not a handbook — it gets loaded, not retrieved. See skills/ in the halogen-workstation-roadmap repo for the sibling convention.
• The retrieval store itself. This repo holds the source-of-truth markdown a human has vouched for. The chunked, embedded index built from it is derived and rebuildable state — it lives beside whichever KB is consuming it, never committed here.

Format

One markdown file per topic at the repo root. Each file should stand as a single admittable document — the same shape a human vouches for at KB admission time.
