provider-codex — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited provider-codex (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 Codex (codex) integration aligned with the upstream CLI. This skill does not define argv/env behaviour — the single mechanical source of truth is UPSTREAM_CLI_CONTRACTS.codex in src/upstream-contracts.ts, enforced by validateUpstreamCliArgs / validateUpstreamCliEnv. Never re-encode flags, sandbox/approval modes, or resume rules here or in TOML.

These values mirror UPSTREAM_CLI_CONTRACTS.codex.upstreamMetadata and docs/upstream/provider-sources.dag.toml ([providers.codex]). The TypeScript metadata is authoritative; the TOML is scanner input only.
codex request fails the upstream contract check before spawn.npm run upstream:scan -- --live reports a change on the Codex release notesor changelog.
controls:
provider_tool_capabilities({cli:"codex"})For a cached read-only resource, use provider-tools://codex.
codex_request for normal implementation/review turns,codex_request_async for long-running work, and codex_fork_session when a real Codex session needs to branch.
model unless the caller explicitly asked for a specific variant; thegateway resolves the configured Codex default/profile.
fullAuto:true when Codex must edit files or run shell commands.Pair it with approvalStrategy:"mcp_managed" for the gateway approval gate.
allowedTools or disallowedTools; Codex does notexpose those request fields through the gateway. mcpServers is approval tracking only because Codex owns its MCP configuration.
sandboxMode, askForApproval, profile, configOverrides, images,outputFormat, and outputSchema only as reported by provider_tool_capabilities.
codex exec resume: pass a real Codex UUIDfrom ~/.codex/sessions/, or resumeLatest:true. Gateway gw-* IDs are not Codex sessions, and fullAuto:true is dropped on resume because Codex inherits the original session approval policy.
