Description
Convert Telegram chat exports into a long screenshot-style image. Supports Telegram Desktop JSON exports with bubble-style message rendering, avatars, timest...
Usage Guidance
This skill appears coherent and performs only local processing of a Telegram JSON export into a PNG. Before running: (1) review the included script yourself since the source is 'unknown'; (2) be mindful of very large exports — rendering extremely tall images can consume a lot of memory/CPU; (3) the only dependency is Pillow (pip install Pillow); (4) the script reads files from disk and writes the image output — it does not appear to perform network I/O or access secrets, but if you plan to share outputs, ensure they don't contain private data. If you need stronger assurance, run it in a sandboxed environment or inspect the complete script file that will be executed.
Capability Analysis
Type: OpenClaw Skill
Name: telegram-chat-to-image
Version: 1.2.1
The skill is a legitimate utility for converting Telegram JSON chat exports into long screenshot-style images using the Pillow library. Analysis of the Python script (scripts/chat_to_image.py) shows standard image rendering logic, local file I/O for reading JSON and writing PNGs, and no evidence of network activity, data exfiltration, or malicious command execution. The SKILL.md instructions accurately describe the tool's purpose without any prompt-injection attempts.
Capability Assessment
Purpose & Capability
Name/description match the code and SKILL.md: the script reads Telegram Desktop JSON and renders a long chat image. No unrelated binaries, cloud services, or credentials are requested.
Instruction Scope
SKILL.md instructs CLI usage (pip install Pillow, run the script with --input/--output) and describes expected input/output. The instructions do not ask the agent to read unrelated files, access environment secrets, or transmit data externally.
Install Mechanism
No install spec is provided (instruction-only), so nothing is written to disk by an automated installer. The only runtime dependency is the well-known Pillow package installed via pip as documented.
Credentials
The skill declares no environment variables, credentials, or config paths. The code uses local filesystem (reading JSON export, optional font files) which is appropriate for the task.
Persistence & Privilege
always is false and the skill does not request persistent system presence or modify other skills. It performs one-off local rendering and writes only the output image (and optionally a ZIP if user follows recommendations).
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install telegram-chat-to-image - After installation, invoke the skill by name or use
/telegram-chat-to-image - Provide required inputs per the skill's parameter spec and get structured output
