Google Drive Access

List, download, and sync files from Google Drive 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 Drive Operation)

CRITICAL: You MUST complete this preflight checklist before running any gdrive commands. Do NOT skip steps.

Step 1: Check CLI Binary Exists

ls -la "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/gdrive-tools/skills/gdrive-access/scripts/gdrive" 2>/dev/null || echo "BINARY_NOT_FOUND"

If BINARY_NOT_FOUND: Build it first:

cd ~/.claude/plugins/marketplaces/cc-skills/plugins/gdrive-tools/skills/gdrive-access/scripts && bun install && bun run build

Step 2: Check GDRIVE_OP_UUID Environment Variable

echo "GDRIVE_OP_UUID: ${GDRIVE_OP_UUID:-NOT_SET}"

If NOT_SET: You MUST run the Setup Flow below. Do NOT proceed to gdrive commands.

Step 3: Verify 1Password Authentication

op account list 2>&1 | head -3

If error or not signed in: Inform user to run op signin first.

---

Setup Flow (When GDRIVE_OP_UUID is NOT_SET)

Follow these steps IN ORDER. Use AskUserQuestion at decision points.

Setup Step 1: Check 1Password CLI

command -v op && echo "OP_CLI_INSTALLED" || echo "OP_CLI_MISSING"

If OP_CLI_MISSING: Stop and inform user:

1Password CLI is required. Install with: brew install 1password-cli

Setup Step 2: Discover Drive OAuth Items in 1Password

op item list --vault Employee --format json 2>/dev/null | jq -r '.[] | select(.title | test("drive|oauth|google"; "i")) | "\(.id)\t\(.title)"'

Parse the output and proceed based on results:

Setup Step 3: User Selects OAuth Credentials

If items found, use AskUserQuestion with discovered items:

AskUserQuestion({
  questions: [{
    question: "Which 1Password item contains your Google Drive OAuth credentials?",
    header: "Drive OAuth",
    options: [
      // POPULATE FROM op item list RESULTS - example:
      { label: "Google Drive API (56peh...)", description: "OAuth client in Employee vault" },
      { label: "Gmail API - dental-quizzes (abc12...)", description: "Can also access Drive" },
    ],
    multiSelect: false
  }]
})

If NO items found, use AskUserQuestion to guide setup:

AskUserQuestion({
  questions: [{
    question: "No Google Drive OAuth credentials found in 1Password. How would you like to proceed?",
    header: "Setup",
    options: [
      { label: "Create new OAuth credentials (Recommended)", description: "I'll guide you through Google Cloud Console setup" },
      { label: "I have credentials elsewhere", description: "Help me add them to 1Password" },
      { label: "Skip for now", description: "I'll set this up later" }
    ],
    multiSelect: false
  }]
})

• If "Create new OAuth credentials": Read and present references/gdrive-api-setup.md
• If "I have credentials elsewhere": Guide user to add to 1Password with required fields
• If "Skip for now": Inform user the skill won't work until configured

Setup Step 4: Confirm mise Configuration

After user selects an item (with UUID), use AskUserQuestion:

AskUserQuestion({
  questions: [{
    question: "Add GDRIVE_OP_UUID to .mise.local.toml in current project?",
    header: "Configure",
    options: [
      { label: "Yes, add to .mise.local.toml (Recommended)", description: "Creates/updates gitignored config file" },
      { label: "Show me the config only", description: "I'll add it manually" }
    ],
    multiSelect: false
  }]
})

If "Yes, add to .mise.local.toml":

1. Check if .mise.local.toml exists
2. If exists, append GDRIVE_OP_UUID to [env] section
3. If not exists, create with:

[env]
GDRIVE_OP_UUID = "<selected-uuid>"

1. Verify .mise.local.toml is in .gitignore

If "Show me the config only": Output the TOML for user to add manually.

Setup Step 5: Reload and Verify

mise trust 2>/dev/null || true
cd . && echo "GDRIVE_OP_UUID after reload: ${GDRIVE_OP_UUID:-NOT_SET}"

If still NOT_SET: Inform user to restart their shell or run source ~/.zshrc.

Setup Step 6: Test Connection

GDRIVE_OP_UUID="${GDRIVE_OP_UUID}" $HOME/.claude/plugins/marketplaces/cc-skills/plugins/gdrive-tools/skills/gdrive-access/scripts/gdrive list 1wqqqvBmeUFYuwOOEQhzoChC7KzAk-mAS

If OAuth prompt appears: This is expected on first run. Browser will open for Google consent.

Drive Commands (Only After Preflight Passes)

GDRIVE_CLI="$HOME/.claude/plugins/marketplaces/cc-skills/plugins/gdrive-tools/skills/gdrive-access/scripts/gdrive"

# List files in a folder
$GDRIVE_CLI list <folder_id>

# List with details (size, modified date)
$GDRIVE_CLI list <folder_id> --verbose

# Search for files
$GDRIVE_CLI search "name contains 'training'"

# Get file info
$GDRIVE_CLI info <file_id>

# Download a single file
$GDRIVE_CLI download <file_id> -o ./output.pdf

# Sync entire folder to local directory
$GDRIVE_CLI sync <folder_id> -o ./output_dir

# Sync with subfolders
$GDRIVE_CLI sync <folder_id> -o ./output_dir -r

# JSON output (for parsing)
$GDRIVE_CLI list <folder_id> --json

Extracting Folder ID from URL

Google Drive folder URL:

https://drive.google.com/drive/folders/1wqqqvBmeUFYuwOOEQhzoChC7KzAk-mAS
                                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                                       This is the folder ID

Drive Search Syntax

Query	Description
name contains 'keyword'	Name contains keyword
name = 'exact name'	Exact name match
mimeType = 'application/pdf'	By file type
modifiedTime > '2026-01-01'	Modified after date
trashed = false	Not in trash
'<folderId>' in parents	In specific folder

Reference: https://developers.google.com/drive/api/guides/search-files

Environment Variables

Variable	Required	Description
GDRIVE_OP_UUID	Yes	1Password item UUID for OAuth credentials
GDRIVE_OP_VAULT	No	1Password vault (default: Employee)

Token Storage

OAuth tokens stored at: ~/.claude/tools/gdrive-tokens/<uuid>.json

• Central location (not in plugin, not in project)
• Organized by 1Password UUID (supports multi-account)
• Created with chmod 600

Post-Execution Reflection

After this skill completes, reflect before closing the task:

0. Locate yourself. — Find this SKILL.md's canonical path before editing.
1. What failed? — Fix the instruction that caused it.
2. What worked better than expected? — Promote to recommended practice.
3. What drifted? — Fix any script, reference, or dependency that no longer matches reality.
4. Log it. — Evolution-log entry with trigger, fix, and evidence.

Do NOT defer. The next invocation inherits whatever you leave behind.
