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 5.1	$0.00064	$0.00930
Opus 5	$0.00032	$0.00465
Sonnet 5	$0.00013	$0.00186
Haiku 4.5	$0.00006	$0.00093

Security

Grade A, and why

init-codex-genome 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 today.

The scan reads SKILL.md. This mod also ships 2 executable files (bundle/portable/.agent-workspace/tooling/genome.py, scripts/genome.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialize and maintain the Codex genome

This skill owns the Codex distribution and adapter. A project has one genome workspace under .agent-workspace/; Claude Code and Codex use that same guidance, roles, lessons, decisions, wiki and task state. Harness-specific instructions, configuration and deployment records remain separate. The project's requirements and deliverables remain project-owned.

Establish the operation

Identify the target project from the request and the current workspace. Resolve it to an absolute path before running a command. Use authorization already given in the conversation. Ask only if the intended project, a material merge decision or authority for the proposed change remains unresolved.

Find this skill's actual directory from the skill path supplied by Codex. Run its scripts/genome.py by absolute path. The script finds the bundle in this installed skill; it does not assume the user's project contains the source repository. Python 3.12 or later is required.

Use init when the project has no .codex/genome-manifest.json. Use update when that manifest already exists. If a complete shared genome workspace is already present, init reuses it and installs only the Codex adapter, Codex standards and Codex tooling. A previous generated Codex installation without the new manifest requires adoption under references/adoption.md, not an ordinary update.

Install or update a project

Inspect the project's existing instructions, overrides, configuration and workflows before deciding what to merge. Establish its real purpose and verification commands from its sources; do not invent project facts to fill a template. Read the selected bundle templates and the deployment plan to understand the proposed changes.

Run a dry run first:

python <skill>/scripts/genome.py init --project <absolute-project-path>
python <skill>/scripts/genome.py update --project <absolute-project-path>

Review the returned operations, conflicts and inventory. The two commands are alternatives for the states described above. Do not infer ownership from a familiar directory name or a generated-file comment. Resolve existing root instructions or local changes through the procedure in references/adoption.md. Preserve project configuration and other skills; the core needs no model, permissions, trust, hook or MCP changes.

What ships with it

43 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.

init-codex-genome is a skill published in the GitHub repository tuannv0069/claude-doc-genome (1 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 930 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-16.
