Persistent Goal Mode

new in CLI 0.128

User-Provided Objective (excerpt)

Build the complete Laravel shop system from specs/* until all acceptance criteria are implemented, independently verified, and documented. Persistent goal mode. Continue until DONE WHEN is fully satisfied or a real blocker occurs. Do not stop early or ask for next steps. ---

Codex was launched with an <untrusted_objective> brief and persistent get_goal / update_goal tools. The agent loops on its own (PLAN → IMPLEMENT → VERIFY → INDEPENDENT QA → FIX → TRACK → COMMIT) until the goal is marked complete. Only one user message was sent during the entire 23h run.

Cost & Tool Usage

$530.26 total

Note: These are hypothetical API costs based on the official GPT-5.5 list prices (≤272K context tier: $5/M input, $0.50/M cache read, $30/M output). This session was run on the Codex Pro plan with fixed monthly pricing, so no per-token charges actually applied. Cache reads were 98.2% of input.

Codex 0.128 assigns each sub-agent a scientist nickname when it spawns. The final three (Anscombe, Gibbs, Arendt) are the independent code reviewer / QA analyst / QA engineer triad called in for the completion audit.

Halley

23:12:09 · explorer · 39 tool calls

You are the planning challenger for the Laravel shop build. Read specs/*.md and specs/progress.md if present. Produce a concise acceptance checklist grouped by vertical slice, call out dependencies/risks, and identify any likely missing implementation areas in the current repo. Do not edit files. Focus on gaps and verification evidence needed. Return concrete file/spec references where possible.

Avicenna

Implement the catalog foundation from specs/01-DATABASE-SCHEMA.md Epic 2 and specs/09-IMPLEMENTATION-ROADMAP.md Phase 2: products, product_...

Kuhn

23:49:59 · explorer · 42 tool calls

Read-only QA analyst for /Users/fabianwesner/Herd/shop.

Zeno

00:10:20 · explorer · 20 tool calls

Read-only Laravel code reviewer for /Users/fabianwesner/Herd/shop. Review the current uncommitted Phase 2 catalog code for Laravel correctness, tenant isolation, migrations/factories/seeders, service logic, tests, and security/validation risks.
