Install prompt-optimizer for Codex and Claude Code

Installs for the current user
codex plugin marketplace add IchenDEV/prompt-optimizer-plugins
codex plugin marketplace upgrade optimize-gpt-5-6-prompts
codex plugin add prompt-optimizer@optimize-gpt-5-6-prompts

Paste and run these commands in a terminal with Codex. They add and refresh the optimize-gpt-5-6-prompts catalog, then install this plugin.

Compatibility: the page URL and API slug “prompt-optimizer-2” remain stable.

  • Codex: prompt-optimizer-2@agent-plugin-marketplace → prompt-optimizer@optimize-gpt-5-6-prompts

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/IchenDEV/prompt-optimizer-plugins

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/prompt-optimizer/.

Included Skills11

audit-gpt-6-astra-skillsskills/audit-gpt-6-astra-skills/SKILL.md

Audit and subtractively clean Skills, AGENTS.md, and coding-agent scaffolding for GPT-6 Astra. Use when Astra stops early, loads the wrong skills, over-reads, over-tests, over-asks, or when migrating Sol-era harness instructions—not for rewriting product prompts (use optimize-gpt-6-astra-prompts).

optimize-claude-fable-5-promptsskills/optimize-claude-fable-5-prompts/SKILL.md

Clarify and rewrite prompts for Claude Fable 5. Use when optimizing, migrating, debugging, or designing a Fable 5 / Fabel prompt (including Fable/Fabel 提示词优化)—not for Claude Opus 5.

optimize-claude-opus-5-promptsskills/optimize-claude-opus-5-prompts/SKILL.md

Clarify and rewrite prompts or agent harnesses for Claude Opus 5 (claude-opus-5). Use when optimizing, migrating from Opus 4.8, or tuning Opus 5 behaviors such as long responses, over-narration, scope expansion, eager subagents, or over-verification (including Opus 5 提示词优化)—not for Claude Fable 5.

optimize-claude-sonnet-5-5-promptsskills/optimize-claude-sonnet-5-5-prompts/SKILL.md

Clarify and rewrite prompts or agent harnesses for Claude Sonnet 5.5 (claude-sonnet-5-5). Use when optimizing, migrating from Sonnet 5, or tuning Sonnet 5.5 behaviors such as effort, initiative/scope, between_tools, JSON accuracy, progress updates, or low-effort verification (including Sonnet 5.5 提示词优化)—not for Opus/Fable prompt rewrites or bare model picking (use select-claude-models).

optimize-deepseek-v4-promptsskills/optimize-deepseek-v4-prompts/SKILL.md

Clarify and rewrite prompts for DeepSeek-V4 Pro and Flash. Use when optimizing, debugging, migrating, or designing a DeepSeek-V4 prompt (including DeepSeek / DeepSeek-V4 提示词优化); keep reasoning modes and special tokens outside prompt prose.

optimize-gemini-promptsskills/optimize-gemini-prompts/SKILL.md

Clarify and rewrite prompts for the Gemini model family. Use when optimizing, debugging, migrating, or designing a Gemini prompt (including Gemini 提示词优化), especially multimodal or long-context cases.

optimize-glm-promptsskills/optimize-glm-prompts/SKILL.md

Clarify and rewrite prompts for the GLM / 智谱 model family. Use when optimizing, debugging, migrating, or designing a GLM prompt (including GLM 提示词优化 or 智谱提示词优化).

optimize-gpt-5-6-promptsskills/optimize-gpt-5-6-prompts/SKILL.md

Clarify and rewrite prompts for GPT-5.6 Sol and the GPT-5.6 family. Use when optimizing, debugging, migrating, or designing a GPT-5.6 prompt (including GPT-5.6 提示词优化)—not for GPT-6 Astra (use optimize-gpt-6-astra-prompts or audit-gpt-6-astra-skills).

optimize-gpt-6-astra-promptsskills/optimize-gpt-6-astra-prompts/SKILL.md

Clarify, migrate, and rewrite product prompts for GPT-6 Astra using OpenAI's latest-model guidance. Use when optimizing, debugging, migrating, or designing a GPT-6 Astra / gpt-6-astra prompt—not for Skills/AGENTS.md harness cleanup (use audit-gpt-6-astra-skills).

optimize-kimi-promptsskills/optimize-kimi-prompts/SKILL.md

Clarify and rewrite prompts for the Kimi model family. Use when optimizing, debugging, migrating, or designing a Kimi prompt (including Kimi 提示词优化).

select-claude-modelsskills/select-claude-models/SKILL.md

Recommend Claude model choices and multi-agent pairings (Opus 想 / Sonnet 干活, advisor-executor, orchestrator-worker). Use when picking among Opus 5.5, Sonnet 5.5, Fable, or Haiku, or designing Claude cost-versus-intelligence routing—not for rewriting a single model's prompt text.
