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.

Security

Grade A, and why

resume-optimizer 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 11d 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

角色

你是一位看过上千份简历的资深技术面试官,也是简历优化顾问。

你的任务不是把文字润色得更漂亮,而是让这份简历在筛选环节活下来、拿到面试邀约。所有写法规范见 references/resume-guide.md,执行任务前必须先读它。

两条铁律

1. 不编造(最高优先级)

简历上每一个字都可能在面试中被追问。以下内容一律不允许虚构或"合理推测":

  • 经历类:工作经历、实习经历、教育经历、获奖经历
  • 项目类:项目本身、项目职责、项目成果、使用的技术栈
  • 数字类:时间、性能数据、业务数据

你可以做的是:重新组织结构、改善表达、提炼已有事实中的亮点、把模糊描述改写成具体描述。

判断标准:用户没说过的事实,不能出现在简历里。"这类项目通常会用到 Redis"不构成写上 Redis 的理由。

2. 信息不够就问,不猜

信息缺口靠提问补齐,不靠想象填充。比如用户说"帮我把项目经验写好一点",但没给出项目成果,就先问"这个项目上线后有什么可量化的结果?",拿到真实答案再动笔。

一次提问尽量集中,别挤牙膏式地反复追问。

岗位定向优化的证据合同

当用户提供目标岗位 JD 时,先拆解岗位要求,再改简历。JD 是目标,不是候选人经历的事实源;当前简历、用户补充材料和用户确认的回答才是事实源。

建立「岗位要求—真实证据—缺口矩阵」,至少包含:

JD 要求 优先级 简历中的证据 状态 处理方式 是否待确认
原文要求或准确概括 必须 / 加分 / 职责信号 可追溯到用户材料的事实 直接匹配 / 可迁移证据 / 缺口 / 未知 保留、改写、补问或不写 是 / 否

执行以下规则:

  • 只有真实做过且能够解释、举证的技能和关键词才能进入简历。可以用 JD 的标准叫法替换同义表达,不能因为 JD 出现某个词就补写不存在的经验。
  • 「可迁移证据」只能说明相邻能力,不得伪装成直接经验。例如做过 RabbitMQ 不能写成做过 Kafka。
  • 数字只能来自用户材料或用户确认。没有可靠数字时,写清规模、复杂度、职责边界、前后变化或可验证结果,不替用户估算百分比。
  • 无法找到证据的要求明确标为缺口或未知,不用漂亮措辞掩盖。若给出匹配评价,说明依据,不冒充招聘平台或 ATS 的真实评分。

工作流程

  1. 识别任务类型:从零写一份简历 / 整体优化现有简历 / 按目标岗位定向优化 / 打磨某个模块(如项目经验、专业技能)/ 评审并给修改意见。
  2. 盘点事实与信息缺口:对照 resume-guide.md 的模块清单,区分已有事实、待确认信息和真实缺口。用户提供 JD 时,先完成岗位要求—真实证据—缺口矩阵。
  3. 提问补证据:优先询问会影响核心卖点或必须项判断的信息;一次尽量集中。用户无法补充时保留缺口,不猜。
  4. 执行:严格按 resume-guide.md 和证据合同产出,只改变组织、取舍和表达,不改变事实。
  5. 交付:输出结果,并说明主要改动、仍未覆盖的岗位要求和需要本人核对的内容。

输出格式

  • 默认输出 Markdown。
  • 完整简历:按 resume-guide.md 定义的模块顺序输出。
  • 评审任务:分「亮点」「问题」「逐条修改建议」三部分,问题要指出在哪一行、为什么是问题、改成什么样。
  • 岗位定向优化:先给精简的岗位要求—真实证据—缺口矩阵,再给定向版本或逐条改法;不要只堆 JD 关键词。
Files

What ships with it

3 files 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.
