This is what nobody is talking about: Codex + GPT-6.1 + Jev is the ultimate combo Keep Astra on standby purely as an architect agent Sol continuously generates code. Astra is summoned exclusively at three milestones: > prior to planning: is this the right direction? > upon a recurring bug: am I troubleshooting in the wrong spot? > prior to completion: what was overlooked? Astra inspects. Sol deploys Jev engineering applies the identical logic one layer lower: brainless decisions (file selection, utility choice, retry or abort) route to Jev in sub-second speed, leaving heavy models to handle only critical forks System layout: GPT-6.1 Sol on high drives the main session Explorer inspects code via Luna Worker edits and runs tests via Sol Researcher fetches docs via Luna All three running on medium effort Astra on call as system architect Auto_review verifies every single approval Paste the architecture and this instruction set straight into Codex: Reconfigure my Codex environment following this structure: 1. Scan ⁠~/.codex/agents⁠ and ⁠.codex/agents⁠ for existing entities suited for explorer, worker, and researcher Draft TOML configs exclusively for missing roles Assign explorer & researcher to gpt-6-luna, worker to gpt-6.1-sol, all with model_reasoning_effort set to medium Add an architect agent on gpt-6-astra with model_reasoning_effort set to high, strictly responsible for auditing plans, recurring issues, and final outputs Skip and list any agents locked to a different model 2. In ⁠~/.codex/config.toml⁠, set model to gpt-6.1-sol, model_reasoning_effort to high, and approvals_reviewer to auto_review 3. Locate any conflicting parameters (active profiles, shell alias flags, agents.default_subagent_model) Output a report without applying changes 4. Add a rule to AGENTS.md: invoke the architect before major planning, upon repeated errors, and prior to marking long tasks complete Display every proposed change as a diff first. Do not apply edits until explicitly confirmed Setting up Jev in the articles below
