A tool for checking whether installed o9k components and related frameworks have updates, and for applying approved safe updates.

Use it to run an update report, apply safe npm-global updates after approval, and refresh host integrations when the stated conditions are met.

It shows what is out of date and separates checking for updates from changing installed files.

o9k-update — Skill for Claude Code by Bumblebiber

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add Bumblebiber/its-over-9k

Claude Code

/plugin install o9k-core

Made for: Claude Code.

Or install o9k-core, the plugin that ships this one along with the rest of its 5 skills, 1 hook.

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	$0.00054	$0.01473
Opus 5	$0.00027	$0.00737
Sonnet 5	$0.00011	$0.00295
Haiku 4.5	$0.00005	$0.00147

Security

Grade A, and why

o9k-update 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 8d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

o9k-update — Keep the Stack Current

o9k checks its dependencies for updates automatically in the background (once per O9K_UPDATE_INTERVAL_HOURS, default 24h) and mentions anything updatable at session start. This skill is the on-demand and apply path.

Check now (read-only)

node "${CLAUDE_PLUGIN_ROOT}/scripts/update-check.mjs" --report

Forces a fresh check (ignores the cache) and prints: each npm-global companion's installed→latest version, both o9k channels (npm global package + git marketplace clone), and the exact commands to apply. Nothing is changed.

Apply the safe updates

Only after showing the report and getting a yes (unless the user has already opted into O9K_UPDATE_CHECK=auto):

node "${CLAUDE_PLUGIN_ROOT}/scripts/update-check.mjs" --apply

Scope: --apply only updates npm-global CLIs (including its-over-9k when installed via npm i -g its-over-9k). Host configs (Codex/Cursor/ OpenCode/Hermes hook wiring, skills) are touched when:

the its-over-9k npm package was just updated (auto-refresh — marketplace files on disk changed), or
O9K_REFRESH_HOSTS=on, or
you run --refresh-hosts separately.

Every file --refresh-hosts writes gets a .o9k-bak backup first.

It deliberately does not touch:

Claude marketplace plugins / git clone — run /plugin marketplace update o9k instead (Claude Code manages that clone; a manual pull could clobber it). After that marketplace update, always run:
```
node "${CLAUDE_PLUGIN_ROOT}/scripts/update-check.mjs" --refresh-hosts
```
Claude picks up new plugin hooks via CLAUDE_PLUGIN_ROOT; other hosts need this re-bake because wrappers bake absolute paths and skills are copies.
Plugins like superpowers / Ponytail — /plugin owns those.
git/uvx tools (Serena) — already always-latest via uvx; npx-based MCPs (Context7) too. Nothing to pin.

Two o9k install channels

Channel	How installed	Update path
npm	`npm i -g its-over-9k`	`--apply` runs `npm i -g its-over-9k@latest`, then auto `--refresh-hosts`
git marketplace	`/plugin marketplace add Bumblebiber/its-over-9k`	`/plugin marketplace update o9k`, then `--refresh-hosts`

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.
