Drive Google Tasks via `curl + jq`. The user's OAuth bearer token is
in `$GOOGLE_TASKS_TOKEN`; every call needs it as
`Authorization: Bearer $GOOGLE_TASKS_TOKEN`. At minimum the token
carries `tasks.readonly` plus the identity scopes
(`openid email profile`); if the user opted in to write at install
time it also carries the broader `tasks` scope (read + write).

The Tasks API returns standard JSON; failures surface as
`{"error": {"code": 401|403|..., "message": "..."}}` — show that
error verbatim. `401` means the token expired (re-install). `403
insufficientPermissions` on a write means the user only granted
`tasks.readonly` — ask them to re-install with the read+write box
checked.

**Always start with `users/@me/lists`** to discover which task lists
the account has — the user's default plus any extras they created on
calendar.google.com or in the Tasks app.

**Before bulk creates / completions / deletes** echo the exact
titles back to the user and ask them to confirm. Don't trash a
task by guessing an id.

## Recipes

### Verify auth + list all task lists (always run first)

```sh
curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
  "https://tasks.googleapis.com/tasks/v1/users/@me/lists" \
  | jq '.items[] | {id, title, updated}'
```

The default list is usually titled "我的任务" / "My Tasks" but the
**id** (a long opaque string like `MTAxMjM0NTY3OA`) is what every
subsequent `lists/{id}/tasks` call needs.

### List all unfinished tasks across every list

```sh
curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
  "https://tasks.googleapis.com/tasks/v1/users/@me/lists" \
  | jq -r '.items[] | "\(.id)\t\(.title)"' | while IFS=$'\t' read LIST_ID LIST_TITLE; do
    curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
      --get "https://tasks.googleapis.com/tasks/v1/lists/$LIST_ID/tasks" \
      --data-urlencode 'showCompleted=false' \
      --data-urlencode 'maxResults=100' \
      | jq --arg list "$LIST_TITLE" '.items[]? | {list: $list, title, due, status, notes}'
  done | jq -s '. | sort_by(.due // "9999")'
```

`showCompleted=false` filters out done items at the API level. The
default `showCompleted=true&showHidden=false` returns done tasks too.

### Pending tasks in one specific list, sorted by due date

```sh
LIST_ID='MTAxMjM0NTY3OA'
curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
  --get "https://tasks.googleapis.com/tasks/v1/lists/$LIST_ID/tasks" \
  --data-urlencode 'showCompleted=false' \
  --data-urlencode 'maxResults=100' \
  | jq '.items // [] | sort_by(.due // "9999") | .[] | {title, due, notes, status, position}'
```

`position` is the user's drag-to-reorder rank inside the list — useful
when the user says "what's at the top of my tasks". Tasks without a
`due` field are open-ended.

### Tasks due today

```sh
TODAY=$(date -u +%Y-%m-%d)
TOMORROW=$(date -u -d "+1 day" +%Y-%m-%d 2>/dev/null \
  || date -u -v+1d +%Y-%m-%d)
TODAY_START="${TODAY}T00:00:00.000Z"
TOMORROW_START="${TOMORROW}T00:00:00.000Z"

curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
  "https://tasks.googleapis.com/tasks/v1/users/@me/lists" \
  | jq -r '.items[] | "\(.id)\t\(.title)"' | while IFS=$'\t' read LIST_ID LIST_TITLE; do
    curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
      --get "https://tasks.googleapis.com/tasks/v1/lists/$LIST_ID/tasks" \
      --data-urlencode "dueMin=$TODAY_START" \
      --data-urlencode "dueMax=$TOMORROW_START" \
      --data-urlencode 'showCompleted=false' \
      | jq --arg list "$LIST_TITLE" '.items[]? | {list: $list, title, due, notes}'
  done | jq -s
```

`dueMin` / `dueMax` are RFC 3339 timestamps. The Tasks API stores
`due` at midnight UTC, so the local-day window is approximate around
the date boundary — that's fine for "due today" semantics, mention
the caveat only if the user pushes back.

### Overdue tasks (everything still pending with a due date in the past)

```sh
NOW=$(date -u +%Y-%m-%dT%H:%M:%S.000Z)
curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
  "https://tasks.googleapis.com/tasks/v1/users/@me/lists" \
  | jq -r '.items[] | "\(.id)\t\(.title)"' | while IFS=$'\t' read LIST_ID LIST_TITLE; do
    curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
      --get "https://tasks.googleapis.com/tasks/v1/lists/$LIST_ID/tasks" \
      --data-urlencode "dueMax=$NOW" \
      --data-urlencode 'showCompleted=false' \
      | jq --arg list "$LIST_TITLE" '.items[]? | {list: $list, title, due, daysOverdue: (((now * 1000) - (.due | sub("Z"; "+00:00") | fromdateiso8601 * 1000)) / 86400000 | floor)}'
  done | jq -s
```

### Recently completed tasks (this week, for a recap)

```sh
ONE_WEEK_AGO=$(date -u -d "-7 days" +%Y-%m-%dT%H:%M:%S.000Z 2>/dev/null \
  || date -u -v-7d +%Y-%m-%dT%H:%M:%S.000Z)

curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
  "https://tasks.googleapis.com/tasks/v1/users/@me/lists" \
  | jq -r '.items[] | "\(.id)\t\(.title)"' | while IFS=$'\t' read LIST_ID LIST_TITLE; do
    curl -sS -H "Authorization: Bearer $GOOGLE_TASKS_TOKEN" \
