provider-gemini — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited provider-gemini (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Process guidance for keeping the gateway's Gemini-compatible provider key (gemini) aligned with Google Antigravity CLI (agy). This skill does not define argv/env behaviour — the single mechanical source of truth is UPSTREAM_CLI_CONTRACTS.gemini in src/upstream-contracts.ts, enforced by validateUpstreamCliArgs / validateUpstreamCliEnv. Never re-encode flags, permission modes, output formats, or resume rules here or in TOML.

sandbox, includeDirs, workspace, worktree, sessionId,resumeLatest, and createNewSession are the relevant controls. JSON or stream-json output, attachments, policy files, admin policy files, and skipTrust are unsupported/rejected in the current Antigravity path.
sessionId or resumeLatest:true.Gateway-generated gw-* IDs are bookkeeping IDs and are rejected if replayed as Gemini session IDs; check the response resumable field.
