Table Image

Generate images from tables for better readability in messaging apps like Telegram. Use when displaying tabular data.

Security Scan

The skill is an instruction-only helper that consistently documents using the open-source tablesnap tool to render markdown tables as PNGs; it is coherent with its purpose but has minor packaging/installation omissions you should know about.

Purpose & Capability

The skill's stated purpose (rendering tables to images) matches the runtime instructions which install and use the tablesnap tool. However, the manifest does not declare required binaries (the instructions require the Go toolchain and git), so the declared requirements are incomplete.

Instruction Scope

SKILL.md stays on-topic: it instructs installing/building tablesnap, piping markdown tables to the tablesnap binary, producing an image file (e.g., /tmp/table.png), and sending it via MEDIA:. It does reference filesystem paths (/tmp) and a one-time emoji download via tablesnap, which are consistent with the skill's goal.

Install Mechanism

There is no formal install spec in the manifest; instead the instructions recommend 'go install' or cloning the GitHub repo and building. Downloading/building from https://github.com/joargp/tablesnap is a common pattern and uses a well-known host, but building/executing code fetched at runtime writes binaries to disk and requires the Go toolchain.

Credentials

The skill requests no environment variables, credentials, or config paths — appropriate for a local rendering tool. There is no apparent need for additional secrets or unrelated credentials.

Persistence & Privilege

always:false and normal invocation behavior. The skill's instructions will create a binary (when the user follows the build/install steps) and write image files (e.g., /tmp/table.png), but it does not request persistent agent-wide privileges or modify other skills.

Assessment

This skill is an instruction-only wrapper around the open-source tablesnap tool and is coherent with its description. Before installing: ensure you have the Go toolchain and git available (the SKILL.md omits these as required binaries); review the tablesnap GitHub repo to confirm you trust the code you will build and run; prefer installing a pinned release rather than 'latest' if you need reproducibility; be aware that building from source and running the binary will execute code retrieved from the internet and will write files (binaries and /tmp images) to your system; the optional 'tablesnap emojis install' will download emoji assets — verify that destination and contents if you care about network downloads.

Table Image Skill

Render markdown tables as PNG images for messaging platforms that don't support markdown tables.

Prerequisites

Install tablesnap:

go install github.com/joargp/tablesnap/cmd/tablesnap@latest

Or build from source:

git clone https://github.com/joargp/tablesnap.git
cd tablesnap
go build -o tablesnap ./cmd/tablesnap

Usage

echo "| Header 1 | Header 2 |
|----------|----------|
| Data 1   | Data 2   |" | tablesnap -o /tmp/table.png

Then send with MEDIA:/tmp/table.png

Options

Flag	Default	Description
-i	stdin	Input file
-o	stdout	Output file
--theme	dark	Theme: dark or light
--font-size	14	Font size in pixels
--padding	10	Cell padding in pixels

Emoji Support

Bundled (work out of the box): ✅ ❌ 🔴 🟢 🟡 ⭕ ⚠️

Full emoji (one-time download):

tablesnap emojis install

Unsupported emoji render as □ until full set is installed.

Example Workflow

# Create table image
echo "| Task | Status |
|------|--------|
| Build | ✅ |
| Deploy | 🚀 |" | tablesnap -o /tmp/table.png

# Send in reply
MEDIA:/tmp/table.png

Notes

• Dark theme by default (matches Telegram/Discord dark mode)
• Auto-sizes to fit content
• Output ~10-20KB (messaging-friendly)
• Cross-platform (Inter font embedded)
