A setup command that adds Memex organization to a workspace. It checks whether the workspace is empty, already contains notes, or has an older Memex setup, then follows the matching setup path.

Use it to create the initial Memex structure, organize existing Markdown files with confirmation, or check an existing installation’s health.

It prepares the workspace for Memex without assuming existing files can be moved or deleted.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00053	$0.01181
Opus 5	$0.00026	$0.00590
Sonnet 5	$0.00011	$0.00236
Haiku 4.5	$0.00005	$0.00118

Security

Grade A, and why

init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memex - Init

Wikilink rule: When referencing any file in markdown you write or edit, always use [[filename]] wikilink format. Never plain text.

Core principle: never assume, never delete. Existing files are sacred. Moves only happen with explicit confirmation.

Step 1: Detect workspace state

Run WORKSPACE_ROOT=$(pwd) && echo "$WORKSPACE_ROOT" via Bash.

State	Detection	Action
Empty	No markdown files, no manifest	Quick Start (below)
Files, no manifest	Markdown exists, no `_MANIFEST.md`	See `references/scan-and-organize.md`
Compatible manifest	`_MANIFEST.md` exists, no `<!-- memex-managed` marker	Offer to add marker (opt in) or continue compatible
Old version	`<!-- memex-managed:X.X.X -->` behind current	Tell the user to run `/memex:upgrade` (one-command migration to current version). Init does not perform the migration itself — see `references/migrations.md` for what changes.
Current version	Current marker	See `references/health-check.md`

Do not announce the detected state. Just run the appropriate flow.

Quick Start (empty workspace)

Ask: "What are you working on right now?". Seeds status.md with active focus, in-progress items, next priorities.
Create from templates/: memory/status.md, memory/session-log.md, memory/decisions.md, memory/glossary.md, memory/_CLOSETS.md (use memory-closets.md.tmpl), scratch/ideas.md.
Append the three Memex lines to workspace-root CLAUDE.md (template at templates/CLAUDE.md.tmpl). Preserve existing content. Skip if .claude/CLAUDE.md already has them.
Create _MANIFEST.md from templates/_MANIFEST.md.tmpl. Tier 1 table, empty Tier 2/3, empty Hub Map. Write last. It's the activation marker.
Print the post-setup message in references/post-setup-message.md.

Scan and Organize (existing files)

See references/scan-and-organize.md for the full scan / analyze / propose / build flow. Closets file format is canonical at memex/skills/session-end/references/closets-format.md; per-entry summary fields follow memex/skills/session-end/references/summary-rules.md.

What ships with it

15 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
