Example session with this skill installed
Use the bundled synthetic file examples/review.csv shown below. Run google-calendar-csv-check examples/review.csv after the README installation and return the full JSON receipt. Do not edit the input, access an account or import/upload anything.

- Read your context and instructions
- Compiled the google calendar event
Synthetic input, measured local CLI result
Executed using the unchanged buyer package v0.1.1 on Windows with Python 3.14. This demonstrates the installed CLI, not automatic agent activation or a native platform test. Input uses UTF-8 and LF newlines; a different save encoding/line ending changes the hash.

Interpretation and next step
Logical row 2 contains February 29, 2026, which is not a valid calendar date. Review the intended date, correct a working copy and rerun. Timezone and existing events are outside this check.
The CLI returned exit code 1 (REVIEW). A separate normal synthetic input returned exit code 0 (PASS_CHECKED_RULES) in the same exact-package replay. A local pass covers only the documented rules; complete the platform's own review before import/upload.
The JSON above is the complete terminal output. No CSV export, account connection, correction or upload was produced by the checker.

About this skill
Before you install: Windows 10/11 on a genuinely local drive; macOS/Linux filesystem inputs are unsupported. Python 3.11+ is required. This is a downloadable source ZIP with a Python CLI and Agent Skill instructions, not a hosted service or one-click desktop app. A terminal (or a compatible agent allowed to run local Python) is required. Prepare trusted pip, setuptools>=68 and wheel for source installation. The core CLI uses only the Python standard library. No connected service account or API key is needed for the local checks; AI assistant/provider fees are separate. Optional local MCP requires its separately installed trusted SDK and local root configuration; it is not required for CLI use.
How to use: Extract the whole ZIP, install from its folder using the README command, and run google-calendar-csv-check <local-file>. Review the JSON receipt, correct any issue yourself in a separate working copy, then rerun before the platform's own manual review. The checker does not change or import your input. Its receipt is printed to the terminal; save it separately if you need a report file.
Short description: Check Google Calendar CSV dates, times, required headers and repeated event rows before manual import. Get a local JSON receipt; no Google account connection.
Description: Calendar CSV imports fail or put events at the wrong dates; inspect dates, times, required headers and repeated events before import. Checks exact Subject/Start Date headers, supported date/time and True/False fields, backwards end boundaries, all-day/time conflicts and repeated same event tuples. Optional dates/times may be absent. Newlines and quoted commas are supported. Includes a Skill, independent Python core/CLI, optional local stdio MCP adapter, setup guide and sample inputs/receipts. Read-only; no remote account access or automatic changes.
Buyer requirements: Windows10/11 on a genuinely local drive; POSIX/macOS/Linux filesystem inputs refused. Trusted Python3.11+ and setuptools68+ for source installation; optional mcp>=2,<3 SDK. Core/CLI runtime is standard-library only. File1000000 bytes, 20000 rows,64 columns,65536 characters/record,128 visible findings. A local result does not guarantee platform acceptance. Local selected-rule check only; no guarantee of remote import. Timezone, recurrence, reminders, account state and existing events are not checked. Dates use MM/DD/YYYY; supported times are 12-hour AM/PM or 24-hour HH:MM. The 1000000-byte cap is conservative; Google documents a 1MB import limit. Native platform validation is a free alternative. No affiliation or endorsement.
Compatibility evidence: Measured CLI examples used Windows and Python 3.14. Agent activation and every host/version combination have not each been tested.
