task-breakdown

task-breakdown is a skill for Claude Code, Codex from Go1c/LumioAgent. It costs 79 tokens per session (877 once invoked), scanned A, original, MIT.

A task-planning workflow that breaks a large or unclear development goal into smaller task cards. Each card describes its scope, dependencies, and objectively checkable acceptance conditions.

In plain words
What is it for?
Use it to prepare work for yourself or other developers, define task dependencies and parallel batches, and make each piece independently verifiable.
Why use it?
It removes ambiguity before implementation and prevents tasks from overlapping or leaving important work uncovered.

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

task-breakdown 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

Task Breakdown(任务拆解)

把一个模糊的大目标切成一组颗粒度合适、互不重叠、可独立完成的任务卡。每张卡都带验收标准,让执行者拿到就能动手,不必回头追问。

何时使用

  • 拿到的目标太大或太模糊,无法直接开工。
  • 一个目标涉及多个文件 / 模块 / 步骤。
  • 需要把工作分派给不同执行者前,先理清边界和顺序。

操作步骤

  1. 澄清。 读目标 + 相关上下文(AGENTS.mdknowledge/、相关源码),找出歧义和缺失信息;能从代码 / 文档确认的先确认,不能确认的明确列为待澄清项。
  2. 切分。 按「能独立完成且可独立验证」的原则切分。一个任务只解决一件事。
  3. 写卡。.spec/tasks/README.md 的格式契约写:一句话目标 / 涉及范围(文件集)/ 验收标准 / 依赖 + 可选「接口」节(Consumes / Produces)——字段口径以该契约为单一权威,此处不复述。有邻卡依赖的卡必须写接口契约(并行 worker 之间唯一的对齐依据),卡内禁占位符(判据见该契约)。深度计划(单功能、含完整代码与逐步验证)用 writing-plans 替代本技能。
  4. 排批。 标出任务间的依赖,划并行批次(wave):同批内无依赖边且涉及文件集互不重叠;给出批序,批间串行(扇出规则见 AGENTS.md「并行边界与合入」)。
  5. 自检。 对照下方「验证」逐条确认。

快速参考

一张卡 = 一个 .spec/tasks/<slug>.md。字段定义与目录纪律的单一权威在 .spec/tasks/README.md,此处只给形状、不复述:

---
status: pending
---

# <一句话目标>

## 涉及范围

- <文件路径 1>
- <文件路径 2>

## 验收标准

- [ ] <可验证的条件 1>
- [ ] <可验证的条件 2>

## 依赖

无(或列前置卡 slug)

注意事项(Pitfalls)

  • 别过度拆解。 能一步做完的事不要拆成多张卡。
  • 验收标准必须可验证。 写「页面好看」不行,写「在移动端 375px 下无横向滚动」才行。
  • 避免重叠。 两张卡改同一处逻辑,是该合并的信号。
  • 待澄清项要显式列出,不要用猜测填空当成已知。

验证

  • 每张卡都能让执行者不追问就开工。
  • 每张卡的验收标准都可客观验证。
  • 所有卡合起来正好覆盖原目标,无遗漏、无重叠、无超范围。
  • 批次划分成立:同批任务无依赖边、文件集无重叠。

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.

task-breakdown is a skill published in the GitHub repository Go1c/LumioAgent (20 stars, last pushed 1mo ago), licensed MIT. It adds 79 tokens to every session and 877 once invoked, about $0.0004 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.
