Install in Gemini CLI

Where Gemini CLI loads installed capabilities from, the path SaferSkills targets, and how to install with the trust score checked first.

SaferSkills installs into Gemini CLI by writing under ~/.gemini/config/, which is both the load path and the config location in the agent manifest. The saferskills install command detects Gemini automatically, shows the capability’s trust score and five-axis breakdown, discloses that it is writing to Gemini, and gates on the aggregate score before anything lands on disk. You can also install by hand from the public catalog.

Where does Gemini CLI load installed capabilities from?

Gemini CLI loads from ~/.gemini/config/, and the same directory is the config location SaferSkills records against. SaferSkills writes a capability into that path on install and reverses exactly what it wrote on uninstall.

SettingValue
Install path~/.gemini/config/
Config file~/.gemini/config/

This path is the agent manifest SaferSkills ships with. SaferSkills only manages the capabilities it placed there — it does not modify the rest of your Gemini configuration.

How do I install with the CLI?

Run install with the catalog name. The CLI resolves the name to a catalog item, prints a digest, discloses that it is writing to Gemini, and then applies the install score gate.

npx saferskills install mcp-server-github

Before any file is written, the CLI shows the aggregate score and the five sub-scores (Security, Supply Chain, Maintenance, Transparency, Community). The gate is the aggregate: below the minimum (default 90, set with SAFERSKILLS_MIN_SCORE) it warns and confirms; a red-tier item (score under 40) requires typing its name. --yes confirms a below-threshold install; --force bypasses only the red-tier name prompt. See install and the global flags.

Inspect first with info (alias check):

npx saferskills info mcp-server-github

uninstall reverses exactly what the CLI wrote under ~/.gemini/config/:

npx saferskills uninstall mcp-server-github

Can I install without the CLI?

Yes. Find the capability in the catalog, open its public report at saferskills.ai/items/<slug>, read the score and findings, then place the files under ~/.gemini/config/ per the author’s instructions. A manual install skips the score gate and the write-disclosure, so read the report — every rule that fired, with a quotable line of evidence — before you copy anything.

What should I know about the trust boundary?

A capability under ~/.gemini/config/ is content the model reads, which makes it an indirect prompt injection surface: the body is exactly the untrusted external content OWASP ranks as the top LLM risk (LLM01

). If you install an MCP server here, its tool descriptions are an additional tool poisoning surface — OWASP MCP03
in the MCP Top 10. SaferSkills scans for both classes — invisible Unicode tag-channel injection, fenced run-this imperatives, description-creep and shadow-tool poisoning — and reports each as a rule_id with the matched evidence.

A few boundary facts:

If you maintain a capability and a finding is wrong, the right of reply lets you prove ownership and post a public response that triggers a re-scan.
