What it does

Base64 Parser is an agent skill from echoVic/blade-code. Base64 编解码工具，支持编码/解码文本、JSON、二进制文件，自动检测格式，支持批量处理

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `README.md` and `scripts/base64_tool.py`).

The repository describes itself as: AI-powered CLI coding agent with 20+ built-in tools, MCP support, and multi-model providers. The licence is MIT.

Example prompts

“/base64-parser”

Requirements

Python 3
Pre-approved tools (allowed-tools): Read, Write, Bash

Workflow steps

4 steps, taken from the step headings in SKILL.md.

解码 Base64
编码为 Base64
检测类型
批量处理

What it can do on your machine

Read from SKILL.md and the folder at commit 30f8684. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Write
- Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
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

Base64 Parser loads about 545 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 97 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~15
When it runs · the whole SKILL.md, loaded when a task matches: ~545

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NotePre-approves every shell command (allowed-tools: Bash)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); the scripts in this folder are not scanned.

Base64 编解码技能

功能

操作	说明
decode	解码 Base64 字符串为文本/JSON/二进制
encode	将文本/文件编码为 Base64
detect	自动检测 Base64 内容类型（JSON/文本/图片/PDF等）
batch	批量解码多个 Base64 字符串

使用方法

重要：始终使用 -p 参数获得人类友好的输出格式！

1. 解码 Base64

bash

# 解码并显示完整内容（推荐）
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p decode "SGVsbG8gV29ybGQ="

# 解码并保存到文件
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p decode "..." --output result.txt

# 解码二进制（如图片）并保存
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p decode "iVBORw0KGgo..." --output image.png --binary

2. 编码为 Base64

bash

# 编码文本
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p encode "Hello World"

# 编码文件
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p encode --file image.png

# URL 安全编码
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p encode "Hello World" --url-safe

3. 检测类型

bash

# 自动检测 Base64 内容类型并显示内容
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p detect "eyJ0ZXN0IjogMX0="

4. 批量处理

bash

# 从文件批量解码（每行一个 Base64）
python3 .blade/skills/base64-parser/scripts/base64_tool.py -p batch --file input.txt --output-dir ./decoded/

输出格式说明

-p (pretty): 人类友好格式，带 emoji 图标，显示完整解码内容
不加 -p: JSON 格式，适合程序处理

示例输出（使用 -p）：

✅ Successfully decoded as JSON

📊 类型: json (application/json)
📏 大小: 35 bytes

📄 解码内容:
--------------------------------------------------
{
  "name": "Blade",
  "version": "2.0"
}
--------------------------------------------------

支持格式

格式	自动检测	说明
JSON	✅	自动解析并格式化输出
纯文本	✅	UTF-8 文本
PNG/JPEG/GIF	✅	通过 magic bytes 检测
PDF	✅	通过 %PDF 头检测
其他二进制	✅	显示十六进制预览

常见场景

解析 JWT Token：JWT 的 payload 是 Base64 编码的 JSON
查看 API 响应：某些 API 返回 Base64 编码的数据
处理配置文件：Kubernetes Secrets 等使用 Base64
图片 Data URI：data:image/png;base64,... 格式
调试加密数据：查看加密前的原始内容

Can I use Base64 Parser in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add echoVic/blade-code --skill base64-parser -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/base64-parser, .gemini/skills/base64-parser, .github/skills/base64-parser and .opencode/skills/base64-parser in your project.

What does Base64 Parser need to run?

Going by SKILL.md and its folder, Base64 Parser needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Bash.

Does Base64 Parser access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Base64 Parser safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Base64 Parser use?

Base64 Parser is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Base64 Parser use?

About 545 tokens (SKILL.md is roughly 2.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
