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.

Model	Per session	Once invoked
Fable 5.1	$0.04068	$0.04068
Opus 5.5	$0.01627	$0.01627
Sonnet 5.5	$0.00814	$0.00814
Haiku 4.5	$0.00407	$0.00407

Security

Grade A, and why

SumSec-Skills CLAUDE.md 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 8d 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.

SumSec-Skills 仓库说明（供 Agent）

本仓库为 SummerSec 个人 Agent Skills 集合，与具体业务代码仓库分离，仅存放可复用的 SKILL.md 及附属资源。仓库以多插件 monorepo 结构管理，Skill 来源包括：

本仓库原创 skill。
submodule 同步：claude-plugins-official、context7、taste-skill-upstream、semantic-linter-upstream。

默认 Git 规则

本仓默认提交目标分支为 master。
除非用户明确要求创建分支、提交 PR，或指定其他分支，否则维护性改动默认应提交并推送到 master。
如果当前不在 master，提交前先确认是否需要切回 master；不要把“默认新建 codex/* 分支”当成本仓默认行为。
GitHub 远端默认分支可能仍显示为 main；提交/推送前用 git branch --show-current 和 git remote show origin 确认当前目标，不要只依赖 remote HEAD。
暂存时只纳入本次任务相关文件，不要使用无差别 git add .。
不要提交无关未跟踪目录、临时输出或同步过程残留，除非本次任务明确要求。

发现与使用

所有 skill 按类别分组在插件目录下：<plugin>/skills/<skill-name>/。
每个 skill 的入口为 <plugin>/skills/<skill-name>/SKILL.md，顶部 YAML frontmatter 中的 description 用于判断是否与任务相关。
当用户任务与某个 skill 的 description 匹配时：先读取并遵循该 SKILL.md，再按需读取其同目录下 references/、scripts/、assets/、rules/ 等由 SKILL.md 直接链接的文件。
执行 skill 时遵守其中的确认门槛、工作流顺序与输出格式要求；不要在未阅读 skill 的情况下用通用流程替代。

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.
