Things URL Scheme

Write operations for Things 3 via the `things:///` URL scheme.

Arguments

`$0` is the command (`add`, `add-project`, `update`, `update-project`, `show`, `search`, `json`); the rest are its `key=value` params. Pass both straight to `url.ts`. A command is required. With none, infer the operation from the request. `capture` routes to `inbox.ts` instead (see [Inbox Capture](#inbox-capture)).

Quick Start

Use `url.ts` for most operations. It handles auth tokens and URL encoding.

bun ${CLAUDE_PLUGIN_ROOT}/scripts/url.ts <command> [key=value ...]

# Bulk update: pass multiple id= params to batch via JSON command
bun ${CLAUDE_PLUGIN_ROOT}/scripts/url.ts update id=X id=Y id=Z when=tomorrow

For raw URL scheme access: `open -g "things:///add?title=Buy%20milk&when=today"`. Use `-g` for data commands to run in background. Omit it for `show`/`search` to foreground Things.

Commands

| Command | Description | Auth required | |---------|-------------|:---:| | `add` | Create a todo | No | | `add-project` | Create a project with optional todos | No | | `update` | Modify a todo's properties | Yes | | `update-project` | Modify a project's properties | Yes | | `show` | Navigate to a list, todo, or project | No | | `search` | Open search with optional query | No | | `json` | Batch create/update via JSON payload | Yes (for updates) |

Full parameters, JSON payload schema, and limits: [url-scheme.md](url-scheme.md). `url.ts` fetches the auth token automatically ([1password.md](1password.md)).

`show` accepts built-in list IDs: `inbox`, `today`, `anytime`, `upcoming`, `someday`, `logbook`, `tomorrow`, `deadlines`, `repeating`, `all-projects`, `logged-projects`.

Tags

Things drops a tag it does not already hold and still reports success. `url.ts` resolves `tags` and `add-tags` against the stored tags first, so an unknown tag fails the call and names itself instead of vanishing from the write. Pass `--create-tags` to create the missing ones:

bun ${CLAUDE_PLUGIN_ROOT}/scripts/url.ts add title="Fix login" tags=bug --create-tags

Matching folds case, so `Bug` resolves to a stored `bug`. An empty `tags=` still clears a todo's tags. Tags inside a raw `json data=...` payload go through unchecked.

Reorder Items

bun ${CLAUDE_PLUGIN_ROOT}/scripts/reorder.ts [--list today|anytime|someday] <id1> <id2> <id3> ...

Items appear at the top of the list in the order specified. Default list is `today`. Use the `--list` value matching the items' current scheduling state. See [Reordering Replaces a Specific Date](#reordering-replaces-a-specific-date).

Inbox Capture

For quick captures to the inbox, use `inbox.ts`. It tags each todo `Claude` and appends session attribution, so prefer it over `url.ts add` when delegating a task mid-session.

bun ${CLAUDE_PLUGIN_ROOT}/scripts/inbox.ts --session-id ${CLAUDE_SESSION_ID} title="Buy milk"

`title` captures one todo. `titles` (newline-separated) captures several at once. Add tags with `--tag` (repeatable). Other params: `notes` (max 10,000 chars), `tags` (comma-separated), `checklist-items` (newline-separated, max 100).

On success it prints a confirmation. With the `x-callback-url` plugin, xcall returns the todo ID and the script prints `https://things.bendrucker.me/show?id=...`. Present that link to the user. Without xcall it prints `captured: <title>`.

Callback

When the `x-callback-url` plugin is installed, `url.ts` uses xcall to get a response from Things on stdout. Present the result as clickable `https://things.bendrucker.me/show?id=<id>` links:

• **Single todo** (`add`, `update`): returns `x-things-id=<id>` — present one link
• **Batch** (`json`): returns `x-things-ids=["id1","id2"]` — present a bulleted list with each todo's title and link

Callback is enabled by default. Disable with `--callback=false` to fall back to fire-and-forget via `open -g`. If xcall is unavailable, the script falls back silently.

Areas

The `list` parameter only works with project names. To file a todo under an area (on create or move), use `list-id` with the area UUID, not `area-id`. Query area IDs via the `things:jxa` skill.

Notes Formatting

Things notes support [Markdown](https://culturedcode.com/things/support/articles/4651820/) plus Things-specific `::highlight::` syntax.

Gotchas

Silent Success

`url.ts` prints only when xcall returns a result. On the fallback path it exits 0 with empty stdout after a successful write, so empty output says nothing about whether the change landed.

Judge failure by a non-zero exit and read stderr for the cause. To confirm a write that printed nothing, query the todo with the `things:jxa` skill. Never retry blind: a repeated `add` creates duplicate todos.

`inbox.ts` and `reorder.ts` do print on success regardless of xcall, so silence from those is a genuine failure.

Reordering Replaces a Specific Date

`reorder.ts` reschedules each item out of the target list and back, because the URL scheme offers no other way to move an item to the top. An item carrying a specific date has that date replaced by the target list, and there is no workaround.

Order within a project is untouched, being separate from scheduling.

Sandbox-blocked URL handoff

If stderr mentions `procNotFound`, `-10810`, or `LSOpenURLsWithRole`, the macOS sandbox blocked the URL handoff to Things. `url.ts` and `inbox.ts` carry the `claude:dangerouslyDisableSandbox` marker so the `mac` plugin's sandbox hook runs them outside the sandbox. If
