OpenLoomi is an open-source desktop AI coworker that connects work tools, gathers context, and highlights decisions or actions needing attention. It is for people managing work across multiple apps, and its catalogue add-ons extend the resident desktop for agent frameworks such as Claude Code, Codex, OpenCode, Hermes, and OpenClaw.
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.

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 | $0.00108 | $0.00536 |
| Opus 5 | $0.00054 | $0.00268 |
| Sonnet 5 | $0.00022 | $0.00107 |
| Haiku 4.5 | $0.00011 | $0.00054 |
Grade B, and why
openloomi-hooks scanned grade B with 1 finding 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 11d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- `/openloomi:hooks install` — merge the bundle into `~/.claude/settings.json` What it actually says
OpenLoomi Hooks Sub-skill
The plugin ships a hook bundle in hooks/hooks.json but never installs it
automatically. Users must explicitly run one of:
/openloomi:hooks install— merge the bundle into~/.claude/settings.json/openloomi:hooks uninstall— strip only the plugin's block (other plugins' hooks are preserved)/openloomi:hooks status— report whether the bundle is currently active
Under the hood this calls:
node ${CLAUDE_PLUGIN_ROOT}/scripts/loomi-bridge.mjs install-hooks
node ${CLAUDE_PLUGIN_ROOT}/scripts/loomi-bridge.mjs uninstall-hooks
node ${CLAUDE_PLUGIN_ROOT}/scripts/loomi-bridge.mjs hooks-status
Safety guarantees
install-hooksis merge-no-overwrite: only adds the plugin's block underhooks.__openloomi_claude_plugin_hooks__. Existing hooks for other plugins are not touched.uninstall-hooksremoves only the plugin-marked block; rerunning it after the first time reportsremoved: false, never deletes anything else's hooks.- The merge is atomic (
writeFileto a temp file, thenrename). - The Stop hook always exits 0 — archive failures are reported as
JSON
{continue: true, _openloomi: {archive: "skipped", reason: ...}}so they can never block Claude Code's response stream.
Suggested user prompt
This plugin can mirror Claude Code's lifecycle onto your Loomi Pet. To enable this, run
/openloomi:hooks install. To disable, run/openloomi:hooks uninstall. The plugin never modifies your~/.claude/settings.jsonwithout explicit consent.
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.

openloomi-hooks is a skill published in the GitHub repository melandlabs/openloomi (1,025 stars, last pushed 10d ago), licensed Apache-2.0. It adds 108 tokens to every session and 536 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
