Usage Guidance
This skill appears coherent and local: it requires bash (4+) and python3, and its scripts produce terminal charts and SVG/HTML files. Before using: 1) Inspect the scripts (they're included) if you want to confirm behavior — they create files (chart_*.svg) in the working directory and a history.log under ~/.local/share/chart-generator (or CHART_DIR). 2) There are no network calls or secret accesses in the code, so data stays on your machine. 3) Be aware the scripts contain some minor shell-code issues (e.g., non-portable/broken arithmetic expressions) that could cause runtime errors — not a security red flag but may cause commands to fail. 4) If you intend to run the skill in a high-security environment, run it in a sandbox or test account first and/or change CHART_DIR to a directory you control.
Capability Analysis
Type: OpenClaw Skill
Name: bytesagain-charts
Version: 1.0.0
The BytesAgain Charts skill bundle is a legitimate tool for generating various types of data visualizations (ASCII, SVG, HTML). The implementation uses Bash scripts (chart.sh, script.sh) to dispatch data to embedded Python logic for rendering. The code includes basic security practices such as filename sanitization (using regex in chart.sh) to prevent path traversal and uses quoted heredocs to prevent shell injection during Python execution. The capabilities provided, such as reading CSV files and writing chart files locally, are strictly aligned with the stated purpose of the skill, and no evidence of data exfiltration, malicious prompt injection, or unauthorized remote access was found.
Capability Assessment
Purpose & Capability
Name/description say 'generate ASCII and HTML/SVG charts from CSV/JSON'. The repository provides bash scripts and an embedded Python SVG generator that implement exactly that. Required tools (bash, python3) match the stated requirements. No extra credentials or unrelated binaries are requested.
Instruction Scope
SKILL.md instructs the agent to run the included scripts (chart.sh / script.sh). Those scripts operate on user-supplied data (CSV/JSON or inline label:value strings), create SVG/html outputs and terminal charts, read CSV files you pass, and write files. They do not access other system credentials or external endpoints. Note: the scripts create a data directory (default ${XDG_DATA_HOME:-$HOME/.local/share}/chart-generator) and a history.log there — this is expected but persistent.
Install Mechanism
No install spec; this is instruction+scripts only. Nothing is downloaded or extracted at install time. Runtime uses only local bash and python3, so install risk is low.
Credentials
No required environment variables, no credentials or secret-looking vars. The scripts respect CHART_DIR/XDG_DATA_HOME for storage location (reasonable), and otherwise only rely on standard shell variables. No unrelated cloud keys or tokens are requested.
Persistence & Privilege
always:false and no autonomous privilege escalation. The skill writes generated charts to the working directory (chart_*.svg) and stores usage history under a per-user data dir (~/.local/share/chart-generator by default). This is normal for a CLI generator but is persistent state on disk.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install bytesagain-charts - After installation, invoke the skill by name or use
/bytesagain-charts - Provide required inputs per the skill's parameter spec and get structured output
