default

default is a skill for Claude Code, Codex from MarecGents/marec-agent-skills. It costs 143 tokens per session (4,041 once invoked), scanned A, original, MIT.

A general-purpose workflow skill for tasks that do not match a more specific skill. It requires brainstorming, file-based planning, skill matching, and an archive step at the end.

In plain words
What is it for?
Use it as a fallback for building, developing, organizing, analysing, or handling a task without a dedicated skill, including work involving GitHub repositories.
Why use it?
It gives unstructured development requests a repeatable process and keeps progress, findings, and the final task record organized. It also requires checking for more suitable skills during planning.

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

default 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.

Default — 通用默认工作流

当你收到一个用户任务,且没有更具体的专项技能匹配时,按照本技能定义的三阶段工作流执行。


核心原则

  1. 必须先调用 brainstorming — 每次任务执行必须先调用 brainstorming 技能进行前期构思和分析,不得跳过此步骤。这帮助你在动手之前全面理解用户意图、项目目标和潜在挑战。
  2. 必须用 planning-with-files 做追踪 — 调用 planning-with-files-zh 技能进行任务文件化追踪,该技能会创建 task_plan.md、findings.md、progress.md 三个核心追踪文件,让整个过程有迹可循、可回溯。
  3. 任务结束后清理并归档 — 基于三个规划文件生成最终的任务日志文档,存入 ./docs/,然后删除过程中产生的无用文件。
  4. 规范统一由 skill-standard-harness 管理 — 操作层面的公共规范(如 GitHub 仓库访问规范、Markdown 输出规范等)由 skill-standard-harness 统一维护,本技能不再重复定义。
  5. 规划阶段必须做技能匹配 — 在任务拆解与规划时,检索可用技能(本仓库及其他已安装技能),为每个子任务匹配最合适的技能,并在最终计划中显式列出「使用某某技能执行某某任务」。避免有现成技能不用、重复造轮子。
  6. 互不相关的子任务必须并行执行 — 若任务包含多个互不相关(无数据/顺序依赖)的子任务,必须开启并行子代理执行而非串行,以最大化效率;有依赖关系的部分保持串行。
  7. 遵守认知纪律 — 执行前先审前提,独立判断不迎合,来源可追溯,有错直说,主动提示盲区;详见「认知纪律与诚实准则」章节。

认知纪律与诚实准则

以下准则适用于本技能三阶段工作流的所有阶段,与工作流规则同等优先。

冲突处理:当本准则与用户即时指令冲突时,默认执行准则;若用户明确要求覆盖,照办,但必须先说明风险。

  1. 先审前提 — 执行前先检查问题本身:是否存在错误前提、逻辑跳跃或信息缺失?发现可疑之处先澄清,不带着未经验证的假设开工。
  2. 独立判断,不一味迎合 — 对用户观点和自身输出都做独立判断,不因顺从而附和。所有信息区分「事实 / 预测 / 主观观点」:事实要求可核实,预测必须标注不确定性,主观观点必须明示立场。
  3. 来源可追溯 — 涉及数字、任务和结论时,尽可能核实并标注信息来源:能核实的给出处(已核实);无法核实的明确标注「推断-未验证」,不以确定语气伪装。
  4. 有错直说 — 发现用户说得不对时,直接指出,并说明三件事:依据(为什么不对)、风险(照原样做的后果)、更合适的解释或做法。
  5. 主动提示盲区 — 主动提醒用户可能忽略的变量、成本与偏差,即使未被问到。

GitHub 仓库访问规范

如果任务涉及从 GitHub 获取仓库代码(如复现项目、下载源码、引用示例等),请调用 skill-standard-harness 技能了解完整的访问规范与操作流程。


三阶段工作流

阶段一:Brainstorming(前期构思 + 技能匹配 + 并行策略决策)
  ↓
阶段二:Planning with Files(文件化执行,含技能映射记录与并行子代理调度)
  ↓
阶段三:任务收尾(归档 + 清理)

阶段一:Brainstorming(前期构思 + 技能匹配)

触发条件:接收到用户任务后立即进入此阶段。

执行步骤:

  1. 调用 brainstorming — 对任务进行初步分析构思。思考:

    • 用户到底想要什么?核心诉求是什么?
    • 这个任务涉及哪些方面?
    • 可能遇到哪些主要挑战?
    • 需要哪些前置条件或资源?
  2. 前提审查(必做) — 在进入方案设计之前,先检查任务本身是否存在:

    • 错误前提 — 用户陈述中与事实不符或未经验证的假设;
    • 逻辑跳跃 — 从诉求到方案之间缺失的推理环节;
    • 信息缺失 — 影响方案成立的关键事实、约束或边界条件。 发现上述问题:按「认知纪律与诚实准则」第 1、4 条向用户澄清或指出,不得带着未验证的假设进入后续步骤。
  3. 遵循 brainstorming 流程:

    • 探索项目上下文(文件、文档、最近的变更)
    • 逐一提出澄清性问题,理解目的、约束和成功标准
    • 提出 2-3 种方案,附上权衡分析和你的推荐
    • 分部分呈现设计,每部分获得用户确认后再继续
    • 将确认后的设计写入设计文档(按 brainstorming 默认路径)
    • 让用户审查书面规格
    • 重要:在用户批准设计之前,不得开始任何实现工作

default is a skill published in the GitHub repository MarecGents/marec-agent-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 143 tokens to every session and 4,041 once invoked, about $0.0006 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 2026-08-31.
