multi-llm-consensus — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited multi-llm-consensus (Agent Skill) and scored it 78/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 1 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.

Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.

Use the local gtwy stdio MCP server to obtain independent evidence from the required provider roster, reconcile disagreements, and continue until every required reviewer gives an unconditional verdict. Do not invoke provider CLIs directly for consensus or review requests.
The complete CLI roster is Claude, Codex, Gemini, Grok, Mistral, Devin, and Cursor. Confirm the live usable roster first with provider_tool_capabilities. A deliberately scoped subset is valid only when the user or governing process explicitly chose it. A required provider that is unavailable is a blocker, not a successful consensus with fewer voters.
Configured API providers are dynamic rather than members of this canonical CLI roster. Discover them with list_models and reported capabilities. They do not have a local CLI checkout/worktree or native ACP guarantee and must not silently replace a required source-inspecting CLI consensus reviewer.
For a mandatory approval review:
and evidence requirements.
APPROVED_UNCONDITIONALLY,CHANGES_REQUIRED, or BLOCKED_EXTERNAL with evidence-backed findings.
Cursor. They reject mcp_managed and their approvalPolicy fields have no effect. Use mcp_managed only for a deliberately configured Claude request.
sandboxMode: "workspace-write" only when it must create build or test artifacts. Do not use fullAuto.
The configured idle-timeout safeguard is only for lack of process output on incremental providers. For terminal-burst providers (gemini, mistral, devin, cursor) it is instead a total-runtime bound, since those emit nothing until exit. That classification is each provider's default invocation; cursor with outputFormat: "stream-json" streams, so there it is a real idle window.
evidence-backed APPROVED_UNCONDITIONALLY. Conditional approval, residual issues, a malformed response, inability to verify, cancellation, timeout, or provider failure is not approval.
Repair findings or evidence and re-dispatch as long as work remains. Stop only on explicit user cancellation or a terminal external provider failure. Preserve that failure as BLOCKED_EXTERNAL with the exact error; never count it as agreement or silently shrink the roster.
For a user who explicitly grants every reviewer full provider permissions and native MCP access, use the full multi-llm-review protocol, not the normal read-only examples below. Build the exact target checkout and start node dist/index.js --transport=stdio from it for the review. Do not use a globally installed or stale gtwy process.
Apply the per-provider full-access controls to each fresh job and verify their live capability. Do not use gateway allowlists or deny lists as a substitute for native MCP access, and do not assume a resumed job retained a grant. Give every reviewer a verification report as a corrective-program specification with the exact base, diff or exhaustive changed-file list, relevant untracked files, and durable job/test evidence. Require direct inspection of source, docs, tests, commands, and native MCP facts. A response must be APPROVED_UNCONDITIONALLY, evidence-backed CHANGES_REQUIRED, or a concrete BLOCKED_EXTERNAL condition. Do not impose caller caps; on a user-required 90-second progress cadence, wait non-blockingly and do not poll early.
| Provider | Local target rule |
|---|---|
| Claude, Codex, Grok, Mistral | Use workingDir on a new session, or select a registered workspace explicitly or by configured default. |
| Gemini | Use workingDir to select the process cwd. includeDirs is auxiliary and does not select cwd. |
| Devin | Use workingDir on a new CLI session, or select a registered workspace explicitly or by configured default. |
| Cursor | Use workingDir for the process cwd. workspace is Cursor's own selector (saved-workspace name, .code-workspace file, or directory); an absolute workspace path disagreeing with workingDir is rejected, not ranked. |
Do not use workspace_* tools to fix a local stdio targeting failure. For managed Claude, a custom working directory or other posture-expanding input needs its gateway approval decision and operator bypass configuration.
Use async gateway tools so the independent reviews can run in parallel. Apply the target rule before each call.

})Poll each job through gtwy with llm_job_status and collect it with llm_job_result. Use non-blocking waits. Do not cancel a required review because it takes a long time.
If persistence.backend = "none" and async tools are not registered, dispatch the same required roster with the corresponding sync request tools. Those calls run to completion without auto-deferral; do not use the absence of async jobs to shrink the review scope.

Claude, Codex, Gemini, Grok, and Mistral accept promptParts. Devin and Cursor accept only flat prompt. Keep a canonical exact review text, deliver it as prompt to Devin and Cursor, and use identical stable structured context for the other five:
codex_request_async({
promptParts: {
system: "Stable consensus review rules",
context: "Stable target paths, revision, and acceptance criteria",
task: "Review independently. Return terminal JSON verdict APPROVED_UNCONDITIONALLY, CHANGES_REQUIRED, or BLOCKED_EXTERNAL with inspected evidence."
},
sandboxMode: "read-only",
workingDir: "[repo]",
approvalStrategy: "legacy"
})Use exactly one of prompt or promptParts. Cache-state resources offer aggregate hashes and token data only. They can validate prefix discipline but never prove review completeness.
Mistral Vibe uses approvalStrategy: "legacy" and defaults its programmatic agent mode to accept-edits. Current Vibe defaults session logging to enabled. Before relying on Mistral resume, run doctor and correct an explicit [session_logging] enabled = false setting.
Codex native continuation requires a real Codex UUID. Do not rely on the resumed target directory: the gateway filters -C/--cd from resume argv, but the child is still spawned with the gateway-resolved cwd. The sandbox posture is not guaranteed to carry over: a resume sandboxMode cannot select one on resume, configOverrides still can, and Codex re-resolves configuration. Each other provider has provider-native continuity; verify the live capability before relying on a stored handle.
SQLite and Postgres persistence retain async jobs durably. Memory persistence is process-lifetime only and needs explicit acknowledgement; persistence.backend = "none" does not register async or job tools. Do not equate a failed persistence surface with a successful review.
Personal Agent Config Kit supports Claude, Codex, and Mistral only and requires durable job admission. It cannot run a complete seven-provider consensus. Treat that as a scope blocker unless the user explicitly chooses a different review scope. The usual workingDir rule does not apply to a Claude or Mistral Kit request: both reject caller-supplied workingDir before context compilation. Use explain_effective_config({workingDir:"<repo>"}) only to inspect a candidate scope, then select that provider's target through an already configured registered workspace alias or the configured default workspace. It never inherits the gateway process cwd.
