                    :regions ((:start 94 :lines 18)))))))
'
```

--------------------------------

### Requirements: External Tools Check

Source: https://context7.com/xenodium/emacs-skills/llms.txt

Checks for the presence of various external command-line tools required by specific Emacs skills. Ensure these are installed and in your PATH if you intend to use the corresponding skills.

### Run D2 Compiler with Theming

Source: https://github.com/xenodium/emacs-skills/blob/main/skills/d2/SKILL.md

Execute the D2 compiler to generate a PNG image from a D2 file. Use `--theme 200` for dark mode or `--theme 0` for light mode, and always include `--pad 40`.

```sh
# Use --theme 200 for dark, --theme 0 for light
d2 --theme 200 --pad 40 /tmp/agent-diagram-XXXX.d2 /tmp/agent-diagram-XXXX.png
```

--------------------------------

### Look Up Emacs Documentation

Source: https://context7.com/xenodium/emacs-skills/llms.txt

--------------------------------

### Open Files in Emacs with emacsclient

Source: https://github.com/xenodium/emacs-skills/blob/main/skills/open/SKILL.md

Use this command to open files in Emacs. Ensure `agent-skill-open.el` is loaded and provide file paths, optionally with specific line numbers. Use absolute paths for files.

```sh
emacsclient --eval \
'(progn
  (load "/path/to/skills/open/agent-skill-open.el" nil t)
  (agent-skill-open
    :files (quote ((:file "/path/to/file1.txt"
            :line 42)

plantuml -tpng /tmp/agent-diagram-XXXX.puml
```

--------------------------------

### Requirements: Check emacsclient PATH

Source: https://context7.com/xenodium/emacs-skills/llms.txt

Verifies that the `emacsclient` executable is available in the system's PATH. This is a prerequisite for using `emacsclient` commands.

```

--------------------------------

### Open Files in Emacs Dired

Source: https://context7.com/xenodium/emacs-skills/llms.txt

Use the `/dired` skill to open files in an Emacs dired buffer. If files share a common directory, dired opens at that directory with files marked. Otherwise, a virtual `*agent-files*` buffer is created.

```emacs-lisp
(progn
  (load "/path/to/skills/dired/agent-skill-dired.el" nil t)
  (agent-skill-dired
    :dir "/src/app"
    :files (quote ("file1.ts"
                   "file2.ts"))))
```

```emacs-lisp
(progn
  (load "/path/to/skills/dired/agent-skill-dired.el" nil t)
  (agent-skill-dired
    :dir "/src"
    :files (quote ("app/file1.ts"
                   "lib/utils.ts"

```

--------------------------------

### Generate Mermaid Diagram Configuration

    "noteBorderColor": "#eeffff"
  }
}
```

--------------------------------

### Generate PlantUML Diagram

Source: https://context7.com/xenodium/emacs-skills/llms.txt

### Generate Gnuplot Script and Plot Data

Source: https://context7.com/xenodium/emacs-skills/llms.txt

Writes a gnuplot script to a temporary file and then executes gnuplot to generate a transparent PNG. The script configures terminal settings, output file, colors, and plots data from a here-document.

```sh
cat > /tmp/agent-plot-$(date +%s).gp << 'EOF'
set terminal pngcairo transparent enhanced size 800,500
set output "/tmp/agent-plot-1700000000.png"

FG = "#eeffff"
set border lc rgb FG
set key textcolor rgb FG
set xlabel "Month" textcolor rgb FG
set ylabel "Sales" textcolor rgb FG
set title "Monthly Sales" textcolor rgb FG
set xtics textcolor rgb FG
set ytics textcolor rgb FG

$DATA << EOD
1 120
2 145
3 98
4 167
5 210
EOD

plot $DATA using 1:2 with linespoints lc rgb FG title "Sales"
EOF

gnuplot /tmp/agent-plot-1700000000.gp
# Output inline:
# ![Monthly Sales](/tmp/agent-plot-1700000000.png)
```
