# Cal.com Access
Manage Cal.com bookings and event types programmatically via Claude Code.
> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
## MANDATORY PREFLIGHT (Execute Before Any Cal.com Operation)
**CRITICAL**: You MUST complete this preflight checklist before running any Cal.com commands. Do NOT skip steps.
### Step 1: Check CLI Binary Exists
```bash
ls -la "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/calcom-cli/calcom" 2>/dev/null || echo "BINARY_NOT_FOUND"
```
**If BINARY_NOT_FOUND**: Build it first:
```bash
cd ~/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/calcom-cli && bun install && bun run build
```
### Step 2: Check CALCOM_OP_UUID Environment Variable
```bash
echo "CALCOM_OP_UUID: ${CALCOM_OP_UUID:-NOT_SET}"
```
**If NOT_SET**: You MUST run the Setup Flow below. Do NOT proceed to Cal.com commands.
### Step 3: Verify 1Password Authentication
```bash
op account list 2>&1 | head -3
```
…Read the whole file at its exact version.
