Base64 encoding and decoding toolkit. Encode/decode text, URL-safe Base64, and image to Base64 conversion.
README (SKILL.md)
Base64 Toolkit
A comprehensive Base64 encoding and decoding tool for developers.
Features
- Encode - Convert text to Base64
- Decode - Convert Base64 back to text
- URL-Safe - URL-safe Base64 encoding (+/- instead of /+)
- Image to Base64 - Convert images to Base64 data URI
Usage
python3 skills/base64-toolkit/scripts/base64_toolkit.py \x3Caction> [options]
Actions
| Action | Description |
|---|---|
encode |
Encode text to Base64 |
decode |
Decode Base64 to text |
encode-url |
URL-safe Base64 encoding |
decode-url |
URL-safe Base64 decoding |
image-encode |
Convert image to Base64 data URI |
Options
| Option | Type | Default | Description |
|---|---|---|---|
--input |
string | - | Input string or file path |
--file |
bool | false | Treat input as file path |
Examples
# Encode text
python3 skills/base64-toolkit/scripts/base64_toolkit.py encode --input "Hello, World!"
# Decode Base64
python3 skills/base64-toolkit/scripts/base64_toolkit.py decode --input "SGVsbG8sIFdvcmxkIQ=="
# URL-safe encode
python3 skills/base64-toolkit/scripts/base64_toolkit.py encode-url --input "Hello+World?"
# URL-safe decode
python3 skills/base64-toolkit/scripts/base64_toolkit.py decode-url --input "SGVsbG8rV29ybGQ_"
# Image to Base64
python3 skills/base64-toolkit/scripts/base64_toolkit.py image-encode --input /path/to/image.png
Use Cases
- API authentication - Encode credentials for Basic Auth
- Data transmission - Safely transmit binary data as text
- URL parameters - Use URL-safe Base64 in URLs
- Image embedding - Embed images in HTML/CSS as data URIs
- JWT tokens - Decode and inspect JWT payload
Current Status
Ready for testing.
Usage Guidance
This appears to be a simple, coherent Base64 utility. Before installing: 1) Fix or confirm the script path in SKILL.md (the examples point to 'skills/base64-toolkit/scripts/...' but the file is at 'scripts/base64_toolkit.py') so the agent can run it reliably. 2) Remember that image-encode and --file read local files and output their Base64 content (including file_path in the JSON); do not point the tool at secrets or sensitive files you don't want to be emitted to agent outputs. 3) You can review and run the script locally (python3 scripts/base64_toolkit.py ...) to confirm behavior. If you plan to encode secrets for use elsewhere, consider doing that locally rather than sending them through an external agent.
Capability Analysis
Type: OpenClaw Skill
Name: base64-toolkit
Version: 1.0.0
The skill bundle provides standard Base64 encoding and decoding utilities, including URL-safe variants and image-to-data-URI conversion. The Python script (scripts/base64_toolkit.py) uses standard libraries without any network activity, external dependencies, or suspicious execution patterns, and all behaviors are consistent with the stated purpose.
Capability Assessment
Purpose & Capability
The name/description (Base64 encode/decode, image-to-data-URI) matches the included Python script and required binary (python3). One minor inconsistency: SKILL.md examples reference path 'skills/base64-toolkit/scripts/base64_toolkit.py' while the repository contains 'scripts/base64_toolkit.py' (README uses the latter). This is likely a documentation/path mismatch rather than malicious behavior, but it may cause runtime failures if the agent attempts the documented path.
Instruction Scope
SKILL.md instructs the agent to run the bundled script and the script's behavior is limited to encoding/decoding and reading local files for file-based input or image-encoding. Reading local files is expected for the stated features. The tool also returns the file_path, base64 string and data URI for image-encode — useful but means any file you point at will have its contents represented in the tool output (be cautious about sensitive files).
Install Mechanism
No install spec; this is an instruction-only skill that relies on an existing python3 binary. No external downloads or third-party package installs are performed.
Credentials
The skill requests no environment variables, credentials, or config paths. That is proportionate for a local Base64 utility.
Persistence & Privilege
The skill does not request permanent presence (always=false) and does not modify other skills or system configuration. Agent autonomous invocation is allowed by default but not a special privilege here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install base64-toolkit - After installation, invoke the skill by name or use
/base64-toolkit - Provide required inputs per the skill's parameter spec and get structured output
