Implement, Review, Fix

Use one parent orchestrator. It may call gateway providers, but provider jobs do not recursively orchestrate other providers. Every review dispatch uses the installed local stdio gateway MCP surface, never a direct provider binary, SDK, connector/shadow gateway, or ad hoc shell fallback.

Outcome contract

The cycle ends only after the final change set has relevant local verification and every required reviewer returns evidence-backed APPROVED_UNCONDITIONALLY. Do not use an arbitrary review-round, turn, token, price, budget, or wallclock cap. A timeout, malformed reply, residual condition, unavailable reviewer, or qualified approval is not approval.

Repair and re-review until all required reviewers approve. If a provider reaches a terminal external failure, retain the error/repair evidence and report INCOMPLETE or BLOCKED; do not silently reduce the review roster. Stop only on explicit user cancellation or after reporting the terminal blocker.

Explicit user-authorized full-access review override

Keep the ordinary implementation and inspection defaults below unless the user explicitly authorizes full provider permissions and native MCP access for the review. In that case, follow the complete multi-llm-review full-access protocol rather than weakening it into a safe-default example: build the target checkout, launch node dist/index.js --transport=stdio from that checkout, and do not use a globally installed or stale gateway process.

Apply the current provider-native full-access control on every new review job, preserve ambient provider MCP configuration without gateway tool allowlists, and do not assume a resumed session retained the grant. Give every reviewer the verification report as a corrective-program specification plus the exact base, diff or changed-file list, and persistent evidence locations. Require independent code, docs, tests, and command inspection. A report claim, intent, or green-check summary is never approval; a disputed finding needs direct code/doc/test evidence.

Do not set caller review caps. When the user requests a 90-second progress cadence, make a non-blocking wait and do not poll earlier. Re-run the complete required roster after every material change until each reachable reviewer returns APPROVED_UNCONDITIONALLY or records a concrete BLOCKED_EXTERNAL condition.

1. Establish the target and roster

1. Capture the exact target repository, base/head or dirty worktree state, changed-file list, relevant specs, and intended invariants.
2. Call cli_versions(), list_models(), and provider_tool_capabilities({cli:"..."}) for Claude, Codex, Gemini, Grok, Mistral, Devin, and Cursor.
3. Use the target-routing matrix in multi-llm-review: explicit workingDir for all seven providers. For Cursor, workspace remains its own native selector, and an absolute workspace path disagreeing with workingDir is rejected rather than ranked. Do not let a default workspace decide the review target. An unscoped child uses a neutral temporary cwd, not the gateway repository.
4. Start an exhaustive CLI review roster with all seven canonical providers. If the user explicitly asks for a narrower scope, record excluded providers and the limitation before dispatching.

approvalStrategy:"mcp_managed" and approvalPolicy are Claude-only. For Claude managed work, workingDir, selectors, native continuation, and other posture changes require an approval decision plus LLM_GATEWAY_APPROVAL_ALLOW_BYPASS=1. Codex, Gemini, Grok, Mistral, Devin, and Cursor use approvalStrategy:"legacy".

2. Implement with an explicit workspace

Gateway tool call:

codex_request({
  prompt:"Implement <feature> in <repo>. Requirements: <requirements>. Update focused tests and report commands actually run.",
  workingDir:"<repo>",
  sandboxMode:"workspace-write",
  approvalStrategy:"legacy",
  correlationId:"implementation"
})

Use sandboxMode:"read-only" only for inspection. fullAuto:true is a deprecated compatibility shorthand for workspace-write; do not use it in new dispatches. A resumed Codex session drops sandboxMode/fullAuto (configOverrides can still set sandbox_mode), so choose a fresh session if the required native posture has changed.

Run the smallest relevant local tests/builds after implementation. Preserve the commands, outputs, change set, and any failures as review evidence.

3. Build the review packet

For a normal read-only Git review, prefer review_changes when its durable SQLite/PostgreSQL validation surface is registered. It constructs the complete hashed committed/staged/unstaged/untracked packet without truncation and starts repository-bound read-only reviewers. Collect its returned validation job_status/job_result references for progress and human visibility. If a judge was requested, wait for terminal results, then call synthesize_validation with the validationId and same repository selector. For review_changes, do not pass caller results as evidence: synthesis ignores caller question/providerResults, reloads exact owned durable linked terminal jobs, reconstructs unavailable requested seats as skipped, and atomically claims the stored judge once. Stored repository, owner, judge, and consent are authoritative. General validation still requires caller question/results. Use the custom packet below when the user-authorized full-access protocol is required or the target is not a Git change set.

Include:

• Base/head identifiers or an explicit uncommitted-worktree statement.
• Exact diff and changed-file list.
• Requirements, invariants, migration/deployment behavior, and docs contract.
• Tests/build/lint/typecheck commands actually run with their outcomes.
• Earlier reviewer findings and evidence-backed responses.

Require reviewers to open source/tests/docs directly and return strict JSON:

{
  "verdict": "APPROVED_UNCONDITIONALLY | CHANGES_REQUIRED | BLOCKED_EXTERNAL",
  "findings": [
    {
      "file": "src/example.ts",
      "line": 1,
      "issue": "...",
      "evidence": "...",
      "suggested_fix": "..."
    }
  ],
  "inspected": ["..."],
  "reviewed_change_identity": "exact diff artifact or exhaustive file list"
}

The packet is a claim, not proof. A reviewer that cannot inspect a claimed input must report CHANGES_REQUIRED with evidence or BLOCKED_EXTERNAL with its exact external access error.

4. Review through the full roster

Use *_request_async when async tools are registered and dispatch the seven provider calls described in multi-llm-review. They are gateway tool calls, not shell commands. Start all required reviewers with the same substantive packet, provider-appropriate target routing, and an explicit strict verdict clause.

• For a pure source review, start Codex with sandboxMode:"read-only"; move to workspace-write only when it must run checks that write artifacts.
• The preceding safe Codex posture is not the explicit full-access override. For that user-authorized case, use the full provider mapping in multi-llm-review, including Codex sandboxMode:"danger-full-access" and dangerouslyBypassApprovalsAndSandbox:true on a fresh session.
• Do not pass Claude allowedTools or tools selectors in a routine managed review. They are high-risk managed inputs, not a way to guarantee access.
• Gemini rejects non-empty allowedTools, skipTrust:true, JSON/stream-JSON output, and unsupported policy/attachment fields in the Antigravity path.
• Devin and Cursor take flat prompt only. Claude/Codex/Gemini/Grok/Mistral can receive promptParts, but it is mutually exclusive with prompt; keep the canonical flat packet for the two providers that do not support it.

SQLite/PostgreSQL jobs survive restarts. Acknowledged memory jobs do not, and persistence.backend = "none" has no async/job tools. Poll with a non-blocking cadence, but never treat cadence as a review deadline.

5. Triage, fix, and re-review

1. Verify every finding against source, tests, docs, or upstream references.
2. Fix correct findings in the target workspace and run focused verification.
3. For a disputed finding, send the same reviewer exact counter-evidence. It must withdraw or revise the finding with evidence; assertion is not rebuttal.
4. Refresh the packet and exact diff after every change.
5. Re-dispatch every reviewer whose prior verdict is not unconditional and any reviewer whose evidence predates the changed diff.
6. Repeat until all required reviewers unconditionally approve the final exact change set.

Session and Kit boundaries

session_create creates gateway bookkeeping, not a generic provider-native conversation. Use a provider-native handle only when the provider response and its capability record say it is resumable. Do not pass a gateway gw-* ID as a native session ID. Codex needs a real Codex UUID or resumeLatest:true; Gemini only reports resumable:true for a caller-supplied usable conversation ID.

Personal Agent Config Kit is local-only and supports only Claude/Codex/Mistral with healthy SQLite/PostgreSQL durable admission. It disables validation and least-cost routing. If an effective Kit profile caps turns or budget, it cannot produce an unconditional exhaustive review. Use explain_effective_config({workingDir:"<repo>"}) first, then obtain an uncapped approved profile or explicit user direction rather than silently lowering the review scope.

That workingDir is valid for read-only Kit inspection only. A Claude or Mistral Kit request rejects caller-supplied workingDir before it compiles context. Target that Kit execution through an already configured registered workspace alias or the configured default workspace. It never inherits the gateway process cwd.

Do not do this

• Do not call a provider CLI directly for implementation review.
• Do not use route_request, select:"cheapest", a cost cap, or a fixed number of review rounds for a mandatory review.
• Do not skip unavailable providers or accept conditional approval.
• Do not use Claude managed approval on a non-Claude request.
• Do not treat cache hashes, a session record, a summary, or a green plan as substitute evidence for inspection and verification.
