CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this repository is

cc-os is a documentation- and design-only repository — there is no application code, build, lint, or test step yet. It captures the design of a personal, cross-project memory system for Claude Code (for a multi-client freelancer) plus the research that informs it. Implementation has not started; the deliverables here are markdown specs, ADRs, and a build outline that a future session turns into a real implementation.

Everything is markdown-as-truth. When asked to "build," the next step is to convert the existing build outline into a staged implementation plan, not to start coding ad hoc.

Directory layout

Numbered files within a directory are not a required reading order — read the one whose topic you need.

• docs/memory-system/ — the design of the memory system itself. Go here to understand or change what is being built. 02-system-design.md is the architecture, 03-architecture- decisions.md is the ADR log (each decision + what was rejected/deferred and why), 04-build-plan.md is the build outline, 06-graphify-evaluation.md justifies the Graphify pivot. Read the specific file relevant to your task; read the whole set only when reworking the design.
• docs/graphify/ — a verified handbook for the Graphify knowledge-graph tool (the chosen knowledge-layer engine). Go here when working with Graphify commands/behavior. Skim 00-README.md for the model, keep 09-best-practices-checklist.md open while actually running it. Claims are provenance-tagged ([github] trustworthy; [interview] / [unverified claim] not).
• graphify-interview, memory-systems-compared060326 (repo root) — raw source transcripts (marketing / video). Only open these to trace where a claim came from; treat as intent, not fact — they were already corrected against primary sources in docs/.
• openspec/ — spec-driven change management (see workflow below). changes/ holds live changes, changes/archive/ completed ones, specs/ stable specs.
• .claude/, .codex/, .pi/ — identical copies of the OpenSpec skills for three AI assistants. Only open when changing a skill — and mirror any change across all three.

The current design in one paragraph

This is a work in progress, not a frozen spec. The paragraph below is the current approach; treat it as the default you operate from, but whenever a conversation with the user changes the design, update this paragraph (and the relevant docs/memory-system/ files + an ADR) to match. Keep it accurate, don't preserve it for its own sake.

Two memory types kept as separate systems: episodic ("what happened, when") handled by memsearch (Milvus Lite, embedded), and semantic/knowledge ("how do we…") handled by a flat Obsidian markdown vault as the single source of truth. Notes keep summary + namespaced tags (tool//client//domain//convention//scope/) as metadata, and the vault is queried via a Graphify knowledge graph (local Ollama SLM for doc extraction, free tree-sitter AST for code). Retrieval is hook-injected + on-demand so project repos stay thin; freshness is lazy (write-time hook + SessionStart reconcile, no daemon/cron); the vault syncs to a VPS while indexes stay disposable and rebuildable. Ships as a global Claude Code plugin with skills.

Recent pivot (2026-06-03): Graphify replaces the originally-planned Ruby/SQLite tag-index CLI and also covers the deferred QMD semantic layer. 04-build-plan.md and 06-graphify-evaluation.md reflect this; if an older doc still describes the Ruby CLI, defer to those two and fix the stale doc.

OpenSpec workflow

Changes are managed spec-driven via OpenSpec. Use the matching skills rather than editing spec files by hand: openspec-explore (think through an idea), openspec-propose (create a change with design/specs/tasks), openspec-apply-change (implement tasks), openspec-verify-change (validate before archiving), openspec-archive-change. Slash commands mirror these under /opsx:*. Live changes live in openspec/changes/, completed ones in openspec/changes/archive/, stable specs in openspec/specs/.

openspec/config.yaml uses schema: spec-driven; its context block is currently empty — project context for OpenSpec artifacts comes from docs/ and this file.

Conventions specific to this repo

• Provenance discipline: when writing about Graphify or anything sourced from the interview transcripts, keep the inline source tags and never promote an [interview] / [unverified claim] to fact without checking a primary source (the GitHub repo is the authority; it was anchored to Graphify v0.8.30).
• Dates are absolute (e.g. 2026-06-03), and design docs carry a _Last updated:_ / status line — keep these current when editing.
• Decisions live in ADRs. Don't silently reverse a locked decision; add or amend an ADR in 03-architecture-decisions.md with the reasoning.
• The package on PyPI is graphifyy (double-y) but the command is graphify.
