Visualize data with bar charts, sparklines, and progress bars in terminal. Use when plotting metrics, rendering inline charts, or transforming data.
README (SKILL.md)
ChartMaker
A data toolkit for chart-related data logging and export. Record, transform, query, and export data entries — all from the command line, all stored locally.
Commands
| Command | What it does |
|---|---|
chartmaker ingest \x3Cinput> |
Log a new ingest entry (no args = show recent entries) |
chartmaker transform \x3Cinput> |
Log a transform entry |
chartmaker query \x3Cinput> |
Log a query entry |
chartmaker filter \x3Cinput> |
Log a filter entry |
chartmaker aggregate \x3Cinput> |
Log an aggregate entry |
chartmaker visualize \x3Cinput> |
Log a visualize entry |
chartmaker export \x3Cinput> |
Log an export entry (see also export with format below) |
chartmaker sample \x3Cinput> |
Log a sample entry |
chartmaker schema \x3Cinput> |
Log a schema entry |
chartmaker validate \x3Cinput> |
Log a validate entry |
chartmaker pipeline \x3Cinput> |
Log a pipeline entry |
chartmaker profile \x3Cinput> |
Log a profile entry |
chartmaker stats |
Show summary statistics across all log files |
chartmaker export \x3Cfmt> |
Export all data to json, csv, or txt format |
chartmaker search \x3Cterm> |
Search all entries for a term (case-insensitive) |
chartmaker recent |
Show the 20 most recent activity log entries |
chartmaker status |
Health check — version, entry count, disk usage |
chartmaker help |
Show usage and available commands |
chartmaker version |
Print version string |
Each logging command (ingest, transform, query, etc.) accepts free-form text. Called without arguments, it shows the 20 most recent entries for that category.
Data Storage
All data is stored locally in ~/.local/share/chartmaker/. Each command category writes to its own .log file, and all actions are recorded in history.log with timestamps.
Requirements
- Bash 4+
When to Use
- Logging chart and visualization data points from the command line
- Tracking data transformations and schema changes over time
- Exporting accumulated entries to JSON, CSV, or plain text for reports
- Searching across all logged entries to find specific visualization data
- Checking health and statistics of your local chart data store
Examples
# Log visualization data
chartmaker ingest "Monthly revenue: Jan=10k Feb=12k Mar=15k"
# Transform and record a data step
chartmaker transform "Normalized Q1 values to percentage scale"
# Search across all logs
chartmaker search "revenue"
# Export everything to CSV
chartmaker export csv
# View recent activity
chartmaker recent

Usage Guidance
This skill appears coherent and local-only, but it will create and write files to ~/.local/share/chartmaker (logs, history, exports). Before installing or using it: review the script if you have sensitive data (to avoid accidentally logging secrets), inspect the export files prior to sharing, and be aware the JSON export implementation has a minor formatting bug (may produce invalid JSON). If you prefer, run it in an isolated account/container first. Because it can be invoked by the agent, confirm you trust the agent to run local commands that read/write your home directory.
Capability Analysis
Type: OpenClaw Skill
Name: chartmaker
Version: 2.0.0
The ChartMaker skill is classified as suspicious due to a major discrepancy between its documentation and implementation. While SKILL.md claims the tool can 'Visualize data with bar charts, sparklines, and progress bars,' the actual code in scripts/script.sh contains no visualization logic and only performs simple text logging to ~/.local/share/chartmaker/. Additionally, the script contains unreachable code (a duplicate 'export' case) that prevents the actual export function from ever running, making the tool a non-functional stub that could mislead an AI agent into reporting a task as complete when no visualization has occurred.
Capability Assessment
Purpose & Capability
Name/description (terminal charts, logging, exports) align with what is implemented: a Bash CLI that logs entries by category, searches, shows stats, and exports data. No unrelated capabilities (cloud access, system config modifications) are requested.
Instruction Scope
SKILL.md and the script are scoped to local logging and export behavior. The script only reads/writes files under $HOME/.local/share/chartmaker, and uses common CLI tools (grep, tail, wc, du). It does not reference other system paths, secrets, or external endpoints.
Install Mechanism
There is no install spec (instruction-only) which is low risk. A single included Bash script implements behavior; no downloads, package installs, or archive extraction occur during install.
Credentials
The skill requests no environment variables, credentials, or config paths. The script uses only $HOME to place its data directory, which is proportional to a local logging tool.
Persistence & Privilege
The skill is not flagged always:true and does not modify other skills or system-wide config. It stores its own logs/exports under the user's home directory only.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install chartmaker - After installation, invoke the skill by name or use
/chartmaker - Provide required inputs per the skill's parameter spec and get structured output
