drogon-gen-advice

drogon-gen-advice is a skill for Claude Code, Codex from voidvec/drogon-claude-plugin. It costs 42 tokens per session (401 once invoked), scanned A, original, MIT.

A code-generation skill for registering Drogon advice, which is Drogon's way to run logic at selected points in request, connection, and session handling. It supports observing an event or intercepting it.

In plain words
What is it for?
Use it to generate registration code for Drogon's built-in advice types, including routing, request handling, response sending, new connections, and session start or destruction.
Why use it?
It helps insert cross-cutting behavior such as logging, access control, security checks, response headers, and session handling without guessing the registration code or callback rules.

Token cost

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.

ModelPer sessionOnce invoked
Fable 5 $0.00042 $0.00401
Opus 5 $0.00021 $0.00200

Security

Grade A, and why

drogon-gen-advice 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 4d 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

drogon-gen-advice

生成 drogon AOP(面向切面)Advice 注册代码。drogon 提供 11 个内建切面。

使用场景

当需要插入横切逻辑(统一日志、安全拦截、响应头注入、连接级访问控制、会话生命周期监听)时,使用此技能。

输入参数

  • advice_type: 切面类型,取值之一:
    • sync(同步拦截,返非空 resp 短路)
    • pre_routing_obs / pre_routing_int(观察/拦截)
    • post_routing_obs / post_routing_int
    • pre_handling_obs / pre_handling_int
    • post_handling(观察)
    • pre_sending(观察,含静态响应)
    • http_response_creation
    • beginning
    • new_connection
    • session_start / session_destroy

输出

  1. 对应 register*Advice(...) 注册代码(放在 app().run() 之前)
  2. 拦截型标注"恰好一次回调"纪律
  3. SyncAdvice 返非空短路示例

示例

/drogon-gen-advice advice_type=pre_routing_obs

Files

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.

Changes

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.
