Ecosystem Update - 2026-06-29

TL;DR

• No automatic harness Quick Win passed the safety gate today; config, hooks, agents, AGENTS policy, skills, and plugins were not mutated.
• OpenAI published Codex CLI 0.142.4 on 2026-06-29 with no identified user-facing changes; PATH is still 0.142.1 and the app bundle is 0.142.3, so this is a deliberate upgrade/smoke task, not an auto-fix.
• Daily community sources produced mostly duplicate or placeholder signal; the strongest new non-duplicate item is Glite ARF's verifier-driven research pattern for parallel Codex/Claude coding campaigns.

Quick Wins

Auto-Implemented

• Backed up config.toml, hooks.json, and all agent TOMLs to /Users/chadsimon/.codex/backups/2026-06-29/.
• Wrote this report to /Users/chadsimon/.codex/reports/ecosystem/2026-06-29.md.
• Updated the ecosystem-update state file.
• No website deployment was performed.

Build Queue

• Codex 0.142.4 PATH/app version reconciliation (Codex-md) - https://github.com/openai/codex/releases/tag/rust-v0.142.4 - Latest stable is 0.142.4; PATH codex is 0.142.1; app-bundled Codex is 0.142.3. Impact 2 / Effort 2. Do as an explicit runtime task with rollback notes plus smoke checks for codex --version, app-bundled CLI, MCP startup, hooks, and a noninteractive dry run.
• Glite ARF corrections-overlay and project-overview adapter (agent-pattern/research) - https://arxiv.org/abs/2606.27416 - Glite ARF uses deterministic verifier scripts, task isolation, immutability of completed work, corrections overlays, and a materialized project overview for many parallel Claude Code/Codex tasks. Impact 2 / Effort 2. The local harness already has planning-gate, validator agents, and AgentOps contracts; the useful gap is a scoped experiment that adds a corrections overlay/project overview artifact for long research or benchmark campaigns without adding a new orchestration service.

Research

• GBC: Gradient-Based Connections for Optimizing Multi-Agent Systems - Fine-grained attribution across agent outputs is relevant to reviewer/worker accountability, but it requires research before any live harness change.
• Glite ARF: Verifier-Driven Research with Parallel LLM Coding Agents - Strong fit for controlled multi-agent campaign evidence; promoted to Build Queue as a bounded adapter idea.
• When Does Personality Composition Matter for Multi-Agent LLM Teams? - Supports keeping coding agents role- and evidence-oriented instead of tuning personality traits for structured coding outcomes.

Already Have

Native ~/.codex/config.toml with schema header, model = "gpt-5.5", review_model = "gpt-5.4", approval_policy = "never", sandbox_mode = "danger-full-access", service_tier = "fast", live web search, hooks enabled, goals enabled, plugins enabled, plugin hooks disabled, native memories disabled in favor of omni-mem, prompt telemetry off, app destructive actions disabled, OpenAI Developer Docs MCP, omni-mem MCP, Wren MCP, node_repl MCP, Browser/Chrome/Computer Use plugins, OpenAI Developers plugin, marketplace/plugin support, read-only explorer/planner/reviewer/validator agents, Python and TypeScript reviewers, workspace-write worker and chad-twin, bounded max_threads, max_depth, and worker runtime, project_doc_fallback_filenames = ["AGENTS.md"], codex-session-search, strict codex-skill-audit, planning-gate, /auto, /drive, /build, /govern, what-would-chad-do, rlm-scan, PreToolUse Bash guard, PostToolUse verification/failure-context hooks, SessionStart RLM/runtime/config posture checks, UserPromptSubmit route classifier, Stop omni-mem save and completion-evidence gate, PreCompact memory capture, config posture checker, AgentOps contract checker, and a large local skill library. Codex best-practice concepts for subagents, skills, plugins, marketplaces, MCP servers, profiles, rules, hooks, and progressive skill disclosure are already covered. Previously seen items skipped today include native memories, plugin hooks, skill catalog audits, deterministic anchoring, NOVA, DynamicMem, policy-as-code, execution-cost tradeoffs, Agent-as-a-Router, and 0.143 alpha release watches.

Rejected

• Auto-upgrade or symlink Codex to 0.142.4 - rejected: binary/path changes require explicit rollback notes and smoke tests, even for no-user-facing maintenance releases.
• Adopt 0.143.0-alpha.29 globally - rejected: alpha releases are under-development features and current runtime policy forbids enabling them globally.
• Treat today's awesome-claude-code commits as a portable pattern - rejected: the 2026-06-29 changes are placeholder README/media churn ending in "Coming soon", with no usable hook, agent, skill, or MCP pattern.
• Install community skill catalogs wholesale - rejected: outside skills require strict audit and a concrete domain need; current setup already has skill-audit, skill-installer, plugin support, and a prior plugin-era posture review item.
• Increase subagent depth to Boris-style nested depth 5 automatically - rejected: local config deliberately keeps max_depth = 1; nested depth needs an eval-backed task before changing global concurrency/context behavior.
• Enable native memories from Codex best-practice tips - rejected: current memory policy uses omni-mem and keeps native Codex memories off.
• Add universal auto-format hooks from community tips - rejected: repo formatters vary and automatic hook wiring changes global edit behavior; existing hooks already record verification and failure context.
• Adopt GBC/AgentChord wholesale - rejected: gradient-style multi-agent attribution is research-heavy and would add complexity before a local failure mode proves it is needed.
• Adopt CHIA or other domain frameworks wholesale - rejected: hardware/software co-design frameworks are too domain-specific for the global Codex harness.
