How to improve

  1. Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec

  • error name-long name is longer than 64 chars
  • warning name-format name should be kebab-case (lowercase letters, digits, hyphens)
  • warning description-short description under 40 chars: too little signal for triggering
  • warning description-no-when description does not say WHEN to use the skill (no "use when")

Process rating: all ten parameters 31/100

  • 0Steps. Prose only: no discrete steps
  • 0Result and completion. Does not say what the result is
  • 0When it triggers. No condition that starts the skill
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Failures and branches. Linear process with no failure handling
  • 0Progress reporting. Says nothing while it works

DO NOT proceed. Inform the user they must restart the gateway. --- ## EXECUTION STEPS ### 1. PROJECT INITIALIZATION - Identify the app name from user intent. Sanitize to lowercase-hyphenated. - **PROJECT PATH**: `/Users/dulorai/projects/[APP_NAME]` - Run initialization: ```bash mkdir -p /Users/dulorai/projects/[APP_NAME] && cd /Users/dulorai/projects/[APP_NAME] && /Users/dulorai/.npm-global/bin/ag-kit init ``` - **VERIFY**: Check if `.agent` folder exists: `ls -la /Users/dulorai/projects/[APP_NAME]/.agent` ### 2. LAUNCH ANTIGRAVITY (WITH READY-CHECK) - **FOCUS**: ensure no other app is interfering. - Launch using ABSOLUTE project path: ```bash /Users/dulorai/.antigravity/antigravity/bin/antigravity /Users/dulorai/projects/[APP_NAME] > /tmp/antigravity_launch.log 2>&1 & ``` - **VERIFY WINDOW & READY STATE**: ```bash for i in {1..15}; do /opt/homebrew/bin/peekaboo sleep 2000 # Wait for internal UI components to ensure project is loaded READY=$(/opt/homebrew/bin/peekaboo see --app Antigravity --json | /usr/bin/jq -r '.data.ui_elements[] | select(.title == "Explorer" or .title == "Chat") | .id' | head -n 1) if [ ! -z "$READY" ]; then break; fi if [ $i -eq 5 ]; then open -n -a Antigravity --args /Users/dulorai/projects/[APP_NAME] >> /tmp/antigravity_launch.log 2>&1; fi done ``` ### 3. ACTIVATE AGENT MODE - **FOCUS**: ```bash /opt/homebrew/bin/peekaboo focus --app Antigravity ``` - Loop `⌘ + L` until the "Code with Agent" chatbox is visible: ```bash for i in {1..5}; do /opt/homebrew/bin/peekaboo hotkey --keys "cmd,l" --app Antigravity /opt/homebrew/bin/peekaboo sleep 2000 VISIBLE=$(/opt/homebrew/bin/peekaboo see --app Antigravity --json | /usr/bin/jq -r '.data.ui_elements[] | select(.title == "Code with Agent") | .id') if [ ! -z "$VISIBLE" ]; then break; fi done ``` ### 4. INJECT COMPLETE BRAINSTORM (SINGLE PROMPT) - **MANDATORY WAIT FOR QUIET**: ```bash while true; do BUSY=$(/opt/homebrew/bin/peekaboo see --app Antigravity --json | /usr/bin/jq -r '.data.ui_elements[] | select((.title | ascii_downcase | contains("stop")) or (.title | ascii_downcase | contains("thinking")) or (.title | ascii_downcase | contains("generating")) or .role == "activityIndicator") | .id') if [ -z "$BUSY" ]; then break; fi /opt/homebrew/bin/peekaboo sleep 4000 done ``` - **FOCUS & TYPE COMPLETE PROMPT IN ONE GO**: ```bash ID=$(/opt/homebrew/bin/peekaboo see --app Antigravity --json | /usr/bin/jq -r '.data.ui_elements[] | select(.role == "textField" or .title == "Code with Agent") | .id' | head -n 1); if [ ! -z "$ID" ]; then /opt/homebrew/bin/peekaboo click --on "$ID"; fi /opt/homebrew/bin/peekaboo type "/brainstorm Continue autonomously using /orchestrator.

MONITOR & UI INTERACTION (THE LOOP) - **LOOP (Run 30 times)**: 1. `/opt/homebrew/bin/peekaboo sleep 5000` 2. **STRICT WAIT FOR AGENT**: ```bash while true; do UI_DATA=$(/opt/homebrew/bin/peekaboo see --app Antigravity --json) ACTIVE=$(echo "$UI_DATA" | /usr/bin/jq -r '.data.ui_elements[] | select((.title | ascii_downcase | contains("stop")) or (.title | ascii_downcase | contains("thinking")) or (.title | ascii_downcase | contains("generating")) or .role == "activityIndicator" or .role == "progressIndicator") | .id') if [ -z "$ACTIVE" ]; then break; fi /opt/homebrew/bin/peekaboo sleep 5000 done ``` 3.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Description length 25: 120–800 characters recommended
  • +4Structure: 1 headings, hard to scan
  • +3No numbered steps or checklist
  • +3Output format is not stated: the model decides each time
