当代码涉及 Excel/CSV/JSON/PDF 大文件导出、批量序列化、内存里构建大对象时触发。防止 OOM、临时文件残留、同步导出阻塞 HTTP 线程等内存安全陷阱。

  • Works in 3 steps: 拆成多个 PDF → 改用专业流式库（iText 商用、ReportLab） → 走异步 + 文件存储
  • Tasks that involve Excel spreadsheets
  • SKILL.md covers 决策：什么时候必须流式？, 陷阱 #1：Excel 大数据 → XSSFWorkbook…, 陷阱 #2：CSV 大文件 → 整文件 readlines… and 陷阱 #3：JSON 大数组导出 →…, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Streaming Export Safety is an agent skill from doccker/cc-use-exp. 当代码涉及 Excel/CSV/JSON/PDF 大文件导出、批量序列化、内存里构建大对象时触发。防止 OOM、临时文件残留、同步导出阻塞 HTTP 线程等内存安全陷阱。

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/multi-lang-examples.md`).

It sits in Documents & Office, covering Excel spreadsheets, CSV and tabular files and PDF. It works with Microsoft Excel, Python, openpyxl and pandas. The repository describes itself as: ⛔ No longer maintained → dev-agent-kit/recipes 让 Claude Code、Antigravity、Gemini CLI、Codex、Cursor 开箱即用的分层配置模板，总结十多年的日常开发经验.

When your agent uses it

  • Tasks that involve Excel spreadsheets
  • Tasks that involve CSV and tabular files
  • Tasks that involve PDF

Example prompts

  • “/streaming-export-safety”

Requirements

  • Python 3
  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. 拆成多个 PDF
  2. 改用专业流式库（iText 商用、ReportLab）
  3. 走异步 + 文件存储

What it can do on your machine

Read from SKILL.md and the folder at commit 64470cb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are java).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Streaming Export Safety loads about 1.9k tokens when it runs, and up to ~4.9k if it reads all its reference files. Until then it costs about 27 tokens; SKILL.md has 315 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 315 words (~1,950 tokens).
