Action space quality 2. Observation quality 3. Recovery quality 4. Context budget quality ## Action Space Design 1. Use stable, explicit tool names. 2. Keep inputs schema-first and narrow. 3. Return deterministic output shapes. 4. Avoid catch-all tools unless isolation is impossible. ## Granularity Rules - Use micro-tools for high-risk operations (deploy, migration, permissions). - Use medium tools for common edit/read/search loops. - Use macro-tools only when round-trip overhead is the dominant cost. ## Observation Design Every tool response should include: - `status`: success|warning|error - `summary`: one-line result - `next_actions`: actionable follow-ups - `artifacts`: file paths / IDs ## Error Recovery Contract For every error path, include: - root cause hint - safe retry instruction - explicit stop condition ## Context Budgeting 1. Keep system prompt minimal and invariant. 2. Move large guidance into skills loaded on demand. 3. Prefer references to files over inlining long documents. 4. Compact at phase boundaries, not arbitrary token thresholds. ## Architecture Pattern Guidance - ReAct: best for exploratory tasks with uncertain path. - Function-calling: best for structured deterministic flows. - Hybrid (recommended): ReAct planning + typed tool execution. ## Benchmarking Track: - completion rate - retries per task - pass@1 and pass@3 - cost per successful task ## Anti-Patterns - Too many tools with overlapping semantics. - Opaque tool output with no recovery hints. - Error-only output without next steps. - Context overloading with irrelevant references. ## 原文 - [英語版の原文](../../../../skills/agent-harness-construction/SKILL.md) ## ナビゲーション - [日本語ドキュメント一覧](../../README.md) - [skills/README.md](../README.md) - [貢献ガイド](../../../../CONTRIBUTING.md)

Install targets
Codex install prompt
Install the "agent-harness-construction" agent skill from https://github.com/loulanyue/awesome-claude-notes/tree/main/docs/ja-JP/skills/agent-harness-construction. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Design and optimize AI agent action spaces, tool definitions, and observation formatting for higher completion rates. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"loulanyue-agent-harness-construction","task":"Install agent-harness-construction","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: docs/ja-JP/skills/agent-harness-construction/SKILL.md. Recorded revision: 6c15cfa1999fbc349d51fefe8187ef43cbb21efd. Confirm the source matches these instructions.
