description	Add a new GeoBrix Cursor command or fix an existing one. Use when the user wants to create/change gbx:* commands or when a command fails and should be fixed (not worked around).

Add or Fix a GeoBrix Cursor Command

Use this skill when adding a new gbx:<category>:<action> command or fixing an existing command (do not work around failures; fix the command).

Command layout

• Location: .cursor/commands/
• Pair: Every command has two files:
  • gbx-<category>-<action>.md — Cursor registration (short description, usage, options). Shown in command palette.
  • gbx-<category>-<action>.sh — Bash implementation. Sourced from Cursor when the command runs.
• Shared helpers: common.sh — check_docker, resolve_log_path, setup_log_file, show_banner, show_separator, open_report. Source it in .sh when needed: source "$SCRIPT_DIR/common.sh".

Naming and ownership

• Format: gbx:<category>:<action> (e.g. gbx:test:function-info, gbx:docker:exec).
• Category must match the subagent that owns the topic (see .cursor/rules/00-agent-context.mdc):
  • test → Test Specialist
  • coverage → Coverage Analyst
  • data → Data Manager
  • docs → Documentation Manager (or Function-Info for function-info only)
  • docker → Docker Specialist
  • gdal → GDAL Expert
  • rasterx / gridx / vectorx → API specialists
• Subagents maintain and improve commands in their domain. After adding or changing a command, update the owning subagent’s .cursor/agents/<name>.md (e.g. document the new option or behavior).

Steps to add a new command

1. Decide category and action from the task (e.g. gbx:docker:logs for tailing container logs). Confirm the owning subagent and that no duplicate command exists (check .cursor/commands/ and .cursor/rules/cursor-commands.mdc).
2. Create the .md file:
   • Short title and 1–2 sentence description.
   • Usage: bash .cursor/commands/gbx-<category>-<action>.sh [OPTIONS].
   • Options (e.g. --log <path>, --help).
   • One or two example invocations.
   • Notes (e.g. “Runs inside Docker”, “Requires geobrix-dev”).
3. Create the .sh file:
   • Shebang: #!/bin/bash.
   • Resolve SCRIPT_DIR and PROJECT_ROOT (see existing commands).
   • Source common.sh if you need Docker check, logging, or banner helpers.
   • Implement options (e.g. --help with show_help; --log with setup_log_path/resolve_log_path).
   • Run the actual logic (often docker exec geobrix-dev ... for tests/docs).
   • Exit with appropriate code and optional success/failure message.
4. Register in cursor-commands.mdc: Add the command to the list under the right category in .cursor/rules/cursor-commands.mdc with a one-line description and example if useful.
5. Update the subagent: In .cursor/agents/<subagent>.md, add or adjust the “Commands” section so the new/fixed command is documented there.

Steps to fix an existing command

1. Reproduce the failure (run the command as the user would).
2. Inspect the .sh (and if relevant .md) under .cursor/commands/. Identify the bug (wrong path, missing check, bad option handling).
3. Change the script (or doc) to fix the behavior. Prefer minimal, clear fixes.
4. Re-run the command to confirm it succeeds.
5. Update the owning subagent file if the fix changes documented behavior or adds options.

Conventions

• Logging: Support --log <path>. Use resolve_log_path and setup_log_file from common.sh so relative paths go under test-logs/ when appropriate.
• Help: Support --help / -h and print usage and options; then exit 0.
• Docker: If the command needs the container, call check_docker early so the user gets a clear error if Docker or geobrix-dev is missing.
• No placeholders: Implement real behavior; do not leave TODOs that make the command a no-op.
