# Add Google Task Goal: add one task to the **default account's default task list** via `gog tasks add`, deriving the content from conversation context and confirming a summary before the write. This skill is **add-only**. Listing, editing, completing, and deleting tasks are out of scope; use `gog tasks` subcommands directly for those. ## Identity stays out of the repo - The task list argument is always `@default`, and `-a` / `--account` is never passed. - "Whose tasks" is resolved by the machine-local gog state (Keychain). The same skill writes to whatever account is default on the machine it runs on — identity and logic stay separated. - Never hardcode an email address, list name, or list ID. ## Workflow ### 0) Preconditions `command -v gog` and `gog auth status` must both succeed. If gog is missing or unauthenticated, point the user to the setup path and stop: ```bash gog auth credentials # one-time client setup gog auth add # add an account ``` ### 1) Derive the task from context (don't interrogate) The trigger is typically terse — "ok, add X to tomorrow's tasks". Build the task from the current conversation instead of asking field by field: - **title** (required) — rewrite the subject as a concise, self-contained task line, not a verbatim quote of the utterance. - **due** (optional) — resolve relative expressions (明日, Friday, next week) against the system clock to `YYYY-MM-DD`. Google Tasks ignores the time-of-day part, so round to a date
