📦 OMP 18.11.0 — Breaking: ApprovalDetailsOptions removed — formatApprovalDetails takes only args again. Also fixes OpenAI/Codex remote compaction refusing or truncating sessions that fit the window: preflight counted the JSON-escaped request, inflating quote-, backslash- and newline-heavy tool output such as disassembly.

📦 Pi 1.2.0 — Per-key OpenRouter model lists (only the models that key may use, with context size, max output, and prices), $schema validation for settings.json, models.json, keybindings, and themes, and PI_CLIPBOARD_OSC52=1 to send copied text to a remote client's clipboard.

Both harness releases extend their extension surfaces: OMP 18.11.0 adds AgentTool.delegationGuidance for same-name extension replacements that delegate to the native tool, and Pi 1.2.0 adds before_agent_start for extension-triggered runs.

📚 Self-Evolving Coding Agents via Harness-Policy Optimization — Self-HPO lets the coding agent improve its own harness, then trains the policy — a recursive framework that alternates harness and policy optimization for coding agents.

📚 τ-Emotion-Bench: Exposing the Interaction Fragility of LLM Agents through Real-World User Emotions — Benchmark exposing LLM agents' interaction fragility in long-horizon tool-calling tasks under real-world user emotions.

📚 Librarian Agents: Training LLMs to Curate Long-Context Workspaces that Anticipate Future Queries — Trains builder agents with reinforcement learning to reorganize document corpora into reusable hierarchical workspaces that anticipate future queries.

📚 New paper: Emerging trends in AI agent evaluation — Chen, Rabanser, Kapoor, and Narayanan map the methods, questions, and ecosystem of AI agent evaluation — amid growing calls for independent eval, what constitutes a 'good' one remains unclear.

Two of today's papers train agents to reshape their own working environment — Self-HPO has the coding agent improve its own harness, Librarian Agents reorganizes document corpora into workspaces that anticipate future queries.
