agent-briefing

agent-briefing is a skill for Claude Code, Codex from cass-2003/local-workflow-skill. It costs 105 tokens per session (12,234 once invoked), scanned A, original, MIT.

A guide for turning vague requests into clear task briefs for coding agents or groups of agents. Each brief states the goal, context, limits, permissions, stopping rules, evidence, and required handoff format.

In plain words
What is it for?
Use it to plan code changes, audits, tests, research, remote work, UI or image tasks, and multi-agent assignments. It also helps define what an agent may do and how it must report back.
Why use it?
It reduces misunderstandings, unsafe assumptions, and hard-to-check results when an agent works with incomplete context or unclear instructions.

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

agent-briefing 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 7d 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.

Agent 提示词简报

Agent 提示词简报(agent-briefing,兼容 slug: apb)负责本技能描述范围内的定位、执行、验证和交接边界;旧短 slug 仅作兼容 alias/URL 主键,不作为规范技能名。

定位:把“让 Agent 去做事”收敛成可委派、可执行、可审计、可验收的任务简报,而不是润色一段提示词。 铁律:没有目标、上下文、边界、权限、停止条件、验收格式,不生成执行型 Agent brief;缺证据时输出缺口,不把假设包装成任务事实。

快速总则

  1. 先判任务类型:只读搜索、代码理解、方案规划、实现修改、测试验证、代码审计、外部调研、远程执行、长任务监控、多 Agent 协作分别生成不同 brief。
  2. Agent brief 的目标是降低跑偏:明确做什么、不做什么、看什么、不能假设什么、允许用什么工具、何时停止、如何回传。
  3. 子 Agent 默认没有完整父上下文;必须把任务背景、已知事实、已排除内容、关键路径、文件、日志、命令、限制和用户原话打包进去。
  4. 用户通常只会说功能、感觉和不满意点;brief 必须把“高级、简单、别花、像人写的、照图做、优化一下”翻译成可执行假设和验收标准。
  5. 描述字段决定路由质量:写清何时使用、何时不用、触发词、反例和交接边界;不要只写“擅长分析问题”。
  6. 权限先于能力:只读、可执行、可编辑、外部写、生产写必须分层;写操作、DB、发布、发消息、改权限、付费和删除默认需要明确授权。
  7. 输出必须可验收:结论要绑定 file:line、命令输出、URL 原文、测试结果、截图、API 样本或“未验证”声明。
  8. 停止条件必须前置:证据不足、影响面扩大、高风险副作用、连续两次无效、工具权限不足、冲突指令、超预算时停止并报告。
  9. 不为了并行而拆 Agent:只有独立子问题、不同专业域、搜索空间过大或需要隔离上下文时才拆;过碎分工会丢失语境。
  10. 不能让子 Agent 接管最终判断:子 Agent 负责收集、验证、局部实现或第二意见;主流程负责综合、取舍和最终交付。
  11. 每个 brief 都要写回传格式;如果不指定,结果会变成散文,难以合并、审计和复验。

口语需求归一化

  1. brief 中保留 user_quote,并新增 normalized_intent;normalized_intent 只写可执行解释,不写空泛审美词。
  2. “优化一下 / 改好看点”:归一成目标用户、当前问题、改动范围、完成状态、验收截图或命令。
  3. “高级 / 现代 / 别土”:归一成低噪声、强对齐、真实组件、少颜色、合适留白、明确主操作和可扫描层级。
  4. “简单 / 极简 / 浅色”:归一成浅色画布、白/浅灰 surface、细边框、少阴影、1 个主色、最多 3 个主导色族。
  5. “看图做 / 复刻”:归一成先抽 layout DSL,再实现;证据不足标 confidence,不要求子 Agent 先写长 brief。
  6. “生图 / 参考图”:归一成画面用途、主体、layout、色彩预算、negative prompt、比例和审图清单;默认浅色极简 UI mockup,除非用户明确要强视觉。
  7. 缺非关键细节时写默认假设并继续;缺平台、权限、真实品牌/人物/IP、生产写或高风险合规时才停止询问。

可复制 brief 片段:

user_quote: "{用户原话}"
normalized_intent: "{把口语需求转成具体目标、范围、视觉/质量标准}"
default_assumptions:
  - UI/image style defaults to light minimal, neutral surfaces, one subdued primary color, max 3 dominant color families.
  - Missing non-critical details are assumptions, not blockers.
acceptance:
  - Output is directly usable or clearly marked unverified.
  - Visual result avoids unnecessary color noise and follows the requested function first.

Agent brief 必填字段

  1. 任务标题:一句话说明本次委派要解决的问题。
  2. Agent 类型:Explore、Plan、general-purpose、测试、审计、研究或远程执行;说明选择理由。
  3. 任务类型:只读、可运行命令、可修改文件、可调用外部 API、可部署;必须和权限匹配。
  4. 背景:用户原始目标、业务目的、当前进度、已知事实、已排除假设、相关约束。
  5. 目标:本次 Agent 必须回答或完成的最小闭环,不写泛化目标。
  6. 非目标:明确不要改什么、不要查什么、不要扩展什么、不要凭什么下结论。
  7. 输入上下文:路径、函数、接口、日志、错误、截图、文档、URL、命令、环境、版本、账号地域和样本。
  8. 搜索范围:允许查看的目录、关键词、API、外部来源和时间范围;缺范围时按只读探索处理。
  9. 工具权限:允许工具、禁止工具、需确认工具、最大命令/查询/轮次数。
  10. 副作用边界:文件写入、DB 写入、生产 API、部署、发通知、创建 PR/issue、删除资源的确认规则。
  11. 执行步骤:建议路径、分叉判断、证据收集顺序、验证方式。
  12. 证据要求:每个结论绑定来源;本地代码用 file:line,外部资料用标题、URL、日期和适用范围。
  13. 停止条件:完成条件、阻塞条件、风险升级条件、预算/时间/轮次上限。
  14. 输出格式:结论、证据、风险、缺口、建议、下一步;必要时给表格字段。
  15. 验收标准:主流程如何判断这个 Agent 的结果可用、不可用或需复查。

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.

agent-briefing is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 2mo ago), licensed MIT. It adds 105 tokens to every session and 12,234 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
