genesis

genesis is a command for Claude Code from XBlueSky/cortexes. It costs 17 tokens per session (1,214 once invoked), scanned A, original, Apache-2.0.

A setup command for a Cortex memory vault, including its configuration, folder structure, and search index. The vault stores notes, projects, weekly reports, and raw session records.

In plain words
What is it for?
Use it to initialize or reconfigure a vault, check or install the Cortex indexing command, choose the vault location, provide author details, and rebuild local indexes.
Why use it?
It prepares the local state needed to record and search personal work history, while reporting when semantic search tools are unavailable.

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.

Security

Grade A, and why

genesis 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 24d 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialize or reconfigure the cortex memory vault. Run once per machine, or again after switching machines to rebuild local state.

Steps

1. Check the cortex-vec CLI

Run command -v cortex-vec. If it is not on PATH, tell the user the vault's indexing and search need the CLI, and offer to install it now:

# Recommended: isolated tool install via uv
uv tool install cortex-vec

# Or with pip
pip install cortex-vec

If they decline, continue anyway — recording and the skills degrade gracefully — but note that semantic indexing and cortex-vec search stay unavailable until it is installed.

2. Check for existing config

Read ~/.cortex/config.json. If it exists, show current config and ask if the user wants to reconfigure or abort.

3. Ask for vault path

If the user provided an argument, use that as the vault path. Otherwise, ask: "Where is the cortex vault? (e.g. /srv/cortex, ~/cortex)"

If the path exists and contains Notes/ or Projects/ or Raw/, recognize it as an existing vault. If the path doesn't exist, ask if they want to create it.

4. Ask for author info

Ask for:

  • Author name (for git commits)
  • Author email (for git commits)

5. Write config

Create ~/.cortex/ directory if needed, then write ~/.cortex/config.json:

{
  "vault_path": "<user's answer>",
  "author": "<name>",
  "author_email": "<email>",
  "git": {
    "auto_commit": true,
    "auto_push": false,
    "commit_trailer": ""
  }
}

git.commit_trailer (string, optional, defaults to ""): when non-empty, the distill and evolve skills append it as the last line of their commit messages, for git hosting setups that expect a specific trailer. Only those two commits, the ones that add new Notes / Projects pages, carry it; raw and broadcast commits do not.

6. Initialize vault structure

Ensure these directories exist in the vault:

  • Raw/
  • Notes/
  • Projects/

Those three are the whole taxonomy. Do not create Weekly/ — it is no longer a Cortexes content type. If an existing vault already has a Weekly/ directory, leave it and its files exactly where they are: never move, rewrite, or delete them. Tell the user it is no longer created, indexed, or searched, and that anything still worth keeping should be moved into Notes/ or Projects/ by hand, at their own pace.

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.

genesis is a command published in the GitHub repository XBlueSky/cortexes (22 stars, last pushed 25d ago), licensed Apache-2.0. It adds 17 tokens to every session and 1,214 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
