Awesome Codex Plugins is a curated catalogue and marketplace of installable plugins, skills, and related resources for OpenAI Codex and ChatGPT. It helps people find, create, validate, and submit extensions for Codex workflows across its app, command-line interface, and IDE extensions. The catalogue add-ons are the plugins, skills, agents, and hooks listed or supported by this project.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.00627 |
| Opus 5.5 | $0.00018 | $0.00251 |
| Sonnet 5.5 | $0.00009 | $0.00125 |
| Haiku 4.5 | $0.00005 | $0.00063 |
Grade A, and why
error-experience-library scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Error Experience Library
用途
- 自动从错误中学习：每次错误解决后，将根因-解决方案对沉淀到经验库
- 历史查询：遇到错误时，先查询经验库是否有已知模式
- 反馈更新：根据实际解决结果更新经验库的成功/失败计数
- 持续优化：高成功率的模式优先推荐，低成功率的模式标记为警示
核心操作
1. 记录错误模式 (record)
当成功解决一个错误后，将经验沉淀：
错误类型: [如: build_error, runtime_error, type_error]
错误信息片段: [可匹配的关键词]
根因: [为什么会发生]
解决方案: [如何修复]
语言/框架: [如: python, typescript, react]
文件模式: [可选，如: **/*.ts]
标签: [如: null-check, async, import]
2. 查询错误模式 (search)
遇到错误时，先查询经验库：
查询关键词: [错误信息或类型]
返回: 按成功率排序的匹配模式
3. 提供反馈 (feedback)
解决方案验证后，更新成功率：
pattern_id: 模式ID
success: true/false
存储位置
- 本地：
~/.claude/memory/error_experience/patterns/ - 每个模式一个 JSON 文件，包含 success_count 和 failure_count
触发信号
- 遇到 build error 或 runtime error 时
- 成功解决错误后，应该记录到经验库
- 使用
/error-lookup命令快速查询
配合约束
- 记录时尽量包含具体的错误信息片段，便于后续匹配
- 根因要具体，不要只写"代码有 bug"
- 解决方案要包含具体的修改内容
- 标签要准确，便于按领域查询
- 验证结果后务必提供反馈，更新成功率

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

error-experience-library is a skill published in the GitHub repository hashgraph-online/awesome-codex-plugins (1,352 stars, last pushed yesterday), licensed Apache-2.0. It adds 46 tokens to every session and 627 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
