GPT-5.6 Sol (Codex) on Find shared calendar slots

Passed in 22s. Attempt 1. Run 20260904T113000Z-gpt-5-6-sol-calendar-slots-1.

Task

Find three shared calendar slots

Read request.md, alice.ics, and bob.ics.

Write slots.json as a JSON array with at least three objects. Each object must have start and end timestamps in ISO 8601 with the Pacific offset, for example:

[{"start":"2026-09-08T10:00:00-07:00","end":"2026-09-08T10:30:00-07:00"}]

Every slot must follow the requested work hours and duration, be free for both people, and leave some space rather than starting or ending at the exact instant of an existing event.

Command

codex exec --skip-git-repo-check --dangerously-bypass-approvals-and-sandbox -m gpt-5.6-sol -c model_reasoning_effort=high --output-last-message /tmp/atris-bench/20260904T113000Z-gpt-5-6-sol-calendar-slots-1/last-message.txt 'You are working in the current folder.

I’m using the calendar workflow because this task requires interpreting shared availability from two ICS calendars. I’ll read the instructions and source files, then validate the resulting JSON.

# Calendar Agent

> Drop this in `~/.claude/skills/calendar/SKILL.md` and Claude Code becomes your calendar assistant.

## Bootstrap (ALWAYS Run First)

Before any calendar operation, run this bootstrap to ensure everything is set up:

` ` `bash
#!/bin/bash
set -e

# 1. Check if atris CLI is installed
if ! command -v atris &> /dev/null; then
  echo "Installing atris CLI..."
  npm install -g atris
fi

# 2. Check if logged in to AtrisOS
if [ ! -f ~/.atris/credentials.json ]; then
  echo "Not logged in to AtrisOS."
  echo ""
  echo "Option 1 (interactive): Run 'atris login' and follow prompts"
  echo "Option 2 (non-interactive): Get token from https://atris.ai/auth/cli"
  echo "                           Then run: atris login --token YOUR_TOKEN"
  echo ""
  exit 1
fi

# 3. Extract token (try node first, then python3, then jq)
if command -v node &> /dev/null; then
  TOKEN=$(node -e "console.log(require('$HOME/.atris/credentials.json').token)")
elif command -v python3 &> /dev/null; then
  TOKEN=$(python3 -c "import json,os; print(json.load(open(os.path.expanduser('~/.atris/credentials.json')))['token'])")
elif command -v jq &> /dev/null; then
  TOKEN=$(jq -r '.token' ~/.atris/credentials.json)
else
  echo "Error: Need node, python3, or jq to read credentials"
  exit 1
fi

# 4. Check Google Calendar connection status (also validates token)
STATUS=$(curl -s "https://api.atris.ai/api/integrations/google-calendar/status" \
  -H "Authorization: [REDACTED]")

# Check for token expiry
if echo "$STATUS" | grep -q "Token expired\|Not authenticated"; then
  echo "Token expired. Please re-authenticate:"
  echo "  Run: atris login --force"
  exit 1
fi

# Parse connected status
if command -v node &> /dev/null; then
  CONNECTED=$(node -e "try{console.log(JSON.parse('$STATUS').connected||false)}catch(e){console.log(false)}")
elif command -v python3 &> /dev/null; then
  CONNECTED=$(echo "$STATUS" | python3 -c "import sys,json; print(json.load(sys.stdin).get('connected', False))")
else
  CONNECTED=$(echo "$STATUS" | jq -r '.connected // false')
fi

if [ "$CONNECTED" != "true" ] && [ "$CONNECTED" != "True" ]; then
  echo "Google Calendar not connected. Getting authorization URL..."
  AUTH=$(curl -s -X POST "https://api.atris.ai/api/integrations/google-calendar/start" \
    -H "Authorization: [REDACTED]" \
    -H "Content-Type: application/json" \
    -d '{"redirect_uri":"https://api.atris.ai/api/integrations/google-calendar/callback"}')

  if command -v node &> /dev/null; then
    URL=$(node -e "try{console.log(JSON.parse('$AUTH').auth_url||'')}catch(e){console.log('')}")
  elif command -v python3 &> /dev/null; then
    URL=$(echo "$AUTH" | python3 -c "import sys,json; print(json.load(sys.stdin).get('auth_url', ''))")
  else
    URL=$(echo "$AUTH" | jq -r '.auth_url // empty')
  fi

  echo ""
  echo "Open this URL to connect your Google Calendar:"
  echo "$URL"
  echo ""
  echo "After authorizing, run your calendar command again."
  exit 0
fi

echo "Ready. Google Calendar is connected."
export ATRIS_TOKEN="$TOKEN"
` ` `

**Important**: Run this script ONCE before calendar operations. If it exits with instructions, follow them, then run again.

## API Reference

Base: `https://api.atris.ai/api/integrations`

All requests require: `-H "Authorization: [REDACTED]"`

### Get Token (after bootstrap)
` ` `bash
TOKEN=$(node -e "console.log(require('$HOME/.atris/credentials.json').token)")
` ` `

### List Events
` ` `bash
# Next 7 days (default)
curl -s "https://api.atris.ai/api/integrations/google-calendar/events" \
  -H "Authorization: [REDACTED]"

# Next N days
curl -s "https://api.atris.ai/api/integrations/google-calendar/events?days=14" \
  -H "Authorization: [REDACTED]"

# Custom date range (ISO 8601)
curl -s "https://api.atris.ai/api/integrations/google-calendar/events?time_min=2026-02-15T00:00:00Z&time_max=2026-02-16T00:00:00Z" \
  -H "Authorization: [REDACTED]"
` ` `

### Get Today's Events
` ` `bash
curl -s "https://api.atris.ai/api/integrations/google-calendar/events/today" \
  -H "Authorization: [REDACTED]"
` ` `

### Get Single Event
` ` `bash
curl -s "https://api.atris.ai/api/integrations/google-calendar/events/{event_id}" \
  -H "Authorization: [REDACTED]"
` ` `

### Create Event
` ` `bash
curl -s -X POST "https://api.atris.ai/api/integrations/google-calendar/events" \
  -H "Authorization: [REDACTED]" \
  -H "Content-Type: application/json" \
  -d '{
    "summary": "Meeting with Hugo",
    "start": "2026-02-15T14:00:00-08:00",
    "end": "2026-02-15T15:00:00-08:00",
    "description": "Discuss project roadmap",
    "location": "Zoom",
    "attendees": ["hugo@atrismail.com"],
    "timezone": "America/Los_Angeles"
  }'
` ` `

**IMPORTANT:** Use `POST` to create events. Do NOT use `PUT` — that is for updating existing events.

### Update Event
` ` `bash
curl -s -X PUT "https://api.atris.ai/api/integrations/google-calendar/events/{event_id}" \
  -H "Authorization: [REDACTED]" \
  -H "Content-Type: application/json" \
  -d '{
    "summary": "Updated meeting title",
    "start": "2026-02-15T15:00:00-08:00",
    "end": "2026-02-15T16:00:00-08:00",
    "timezone": "America/Los_Angeles"
  }'
` ` `

### Delete Event
` ` `bash
curl -s -X DELETE "https://api.atris.ai/api/integrations/google-calendar/events/{event_id}" \
  -H "Authorization: [REDACTED]"
` ` `

### Check Connection Status
` ` `bash
curl -s "https://api.atris.ai/api/integrations/google-calendar/status" \
  -H "Authorization: [REDACTED]"
` ` `

### Disconnect Google Calendar

curl -s -X DELETE "https://api.atris.ai/api/integrations/google-calendar" \
  -H "Authorization: [REDACTED]"
` ` `

1. Run bootstrap
2. Get events: `GET /google-calendar/events?days=7`
3. Group by day, display each day's events

### "Schedule a meeting with X"

2. Create event: `POST /google-calendar/events` with summary, start, end, attendees
3. Confirm: "Meeting created! [link]"

### "Do I have any meetings this afternoon?"
1. Run bootstrap
2. Get events: `GET /google-calendar/events/today`
3. Filter events where start time is after 12:00 PM in user's timezone
4. Display matching events or "No meetings this afternoon."

### "When is my next meeting?"
1. Run bootstrap
2. Get events: `GET /google-calendar/events/today`
3. Find the next event after current time
4. Display: "Your next meeting is [title] at [time]" or "No more meetings today."

### "Cancel my 3pm meeting"
1. Run bootstrap
2. List events: `GET /google-calendar/events/today`
3. Find event at 3pm
4. **Confirm with user** before deleting
5. Delete: `DELETE /google-calendar/events/{event_id}`

## Display Format

When showing calendar events, use this format:

` ` `
Today's Schedule (Feb 15, 2026)

  9:00 AM - 9:30 AM   Team Standup
                       Google Meet

# Find three shared calendar slots

Read `request.md`, `alice.ics`, and `bob.ics`.

Write `slots.json` as a JSON array with at least three objects. Each object must have `start`
and `end` timestamps in ISO 8601 with the Pacific offset, for example:

` ` `json
[{"start":"2026-09-08T10:00:00-07:00","end":"2026-09-08T10:30:00-07:00"}]
` ` `

Every slot must follow the requested work hours and duration, be free for both people, and leave
some space rather than starting or ending at the exact instant of an existing event.
Today is Mon 2026-09-07. Find three 30-minute slots this week, Tuesday through Friday,
9:00 AM to 5:00 PM Pacific, when Alice and Bob are both free. A proposed slot must not touch
an existing event at either end.

The calendars have multiple clean gaps with 15-minute buffers. I’m selecting three 30-minute slots on separate days so none touches an event boundary.
