description	USER-INVOKED ONLY. Use only when the user explicitly invokes $of or $op, or explicitly names this skill to open/view a local file. Never invoke implicitly. Opens visualizable files such as images, Mermaid, Markdown, HTML, PDF, and text using the system default app.

Open File

Open one local file the user explicitly asks to view.

Human-invoked only. Do not activate implicitly from a merely mentioned path or artifact.

Input

Optional:

path: <file path>

If no path is provided, infer the target from the most recent concrete local file path in the conversation or tool output. Prefer generated/opened artifacts over their sources when the user says "open it", "view it", "$of", or "$op" without a path.

Workflow

1. Pick the target:
   • explicit path in the user prompt wins;
   • otherwise use the latest unambiguous local file path from context;
   • if several files are equally plausible, ask one short question.
2. Resolve the path against the current working directory when relative. Expand ~ to $HOME; do not use shell eval.
3. Verify the file exists before opening it.
4. Open with the platform default viewer:
   • Linux: xdg-open -- "$path"
   • macOS: open "$path"
   • Windows/Git Bash: start "" "$path"
5. Run the opener in the background when the terminal command would otherwise block. Report the exact file opened.

Guardrails

• Open local files only. For URLs or remote resources, use the normal browser tooling only when the user clearly asked for that.
• Do not modify, render, convert, or regenerate the file unless the user asked.
• Do not guess between multiple candidate files with the same recency.
