chore: initial commit — portable agent memory & skill scaffold

Extracted and cleaned up from a prior WSL/Windows agent-memory setup.
Contains only project-agnostic content:

- Claude_Memory/: feedback rules, user profile, reusable reference docs,
  session scratch space (claude_info/, claude_log/), mirrored skill defs
- caveman/: ultra-compressed communication mode skill + subcommands
- html-slide-deck/: self-contained HTML slide deck builder skill

Project-specific knowledge (previously mixed in) was moved out to each
project's own repository as part of this cleanup.

+# Agent Memories
+
+A portable, project-agnostic memory and skill scaffold for AI coding agents (Claude Code, Gemini/Antigravity, and similar).
+
+The core idea: an agent that works across many different codebases accumulates two kinds of knowledge —
+knowledge that is useful *everywhere* (how you like to communicate, how you like commits done, reusable
+tool workflows) and knowledge that only makes sense for *one specific project* (its language, its build
+system, its domain quirks). Mixing the two makes the "everywhere" knowledge unusable when you switch to a
+different project. This repository keeps only the first kind. Project-specific knowledge lives inside each
+project's own repository instead.
+

+### Memory file conventions (`Claude_Memory/`)
+
+| Prefix | Meaning | Changes how often? |
+|---|---|---|
+| `feedback_*.md` | A behavioral rule learned from an explicit user correction or confirmation. Each file states the rule, **why** it exists, and **how** to apply it. | Rare — only when the user corrects or confirms an approach |
+| `user_*.md` | Stable facts about the user: preferences, working style, profile. | Rare |
+| `reference_*.md` | Documentation for a reusable tool or workflow that isn't tied to any one project. | Occasional |
+| `claude_info/*.md` | Short-lived session scratch space (current status, discoveries, todos). | Every session |
+| `claude_log/*.md` | Dated logs of non-obvious discoveries, kept for future reference. | Per notable discovery |
+
+**Rule of thumb**: if a note only makes sense to someone who already knows the specific project you were
+working in, it does not belong here — move it into that project's own memory/notes instead. This repository
+was extracted from a working setup that originally mixed both kinds of content; project-specific material
+was moved out during that cleanup.
