Google Sheets Row Sync
Write app records into a chosen Google Sheet as clean, correctly mapped rows.
What it adds
A configured append or upsert of app records into a selected spreadsheet and worksheet under an explicit column mapping.
What your agent is told to do
5
What your agent is told to do
5-
1
Have the user pick the spreadsheet, the worksheet, and the field-to-column mapping explicitly at setup, and show them a sample row before the mapping is saved.
-
2
Resolve columns by their header text read at write time rather than by fixed position, and stop the write with a clear message when a mapped header is missing instead of writing into the neighbouring column.
-
3
Decide per destination whether rows are append-only or keyed. When they are keyed, carry a stable app identifier in its own column and update the matching row rather than appending a second one.
-
4
Neutralize any user-supplied value a spreadsheet would interpret as a formula before writing it, so a submitted field cannot execute in whoever opens the sheet.
-
5
Queue writes through the app's existing background-job system and batch them. Do not write a row inline during a form submission, because a slow or rate-limited provider would then make the user's submission fail.
Edge cases it handles
8
Edge cases it handles
8- A user who reorders columns breaks a position-based mapping silently, and data keeps flowing into the wrong fields until somebody notices. Resolve by header and verify before writing.
- A mapped column that has been renamed or deleted must halt the write with a message naming the column, not drop the value or add a new column unannounced.
- A retried job with no stable key appends the same record a second time. Keyed destinations must update in place, and append-only destinations must at least be able to detect the duplicate.
- Text beginning with an equals sign, a plus, a minus, or an at sign is executed as a formula by spreadsheet software. Escape it, because an unescaped value from a public form is an attack on whoever opens the sheet.
- Provider quotas are low relative to a busy app. Batch rows and retry with backoff, holding the queue rather than discarding records once the quota is exhausted.
- Any editor can revoke access to the sheet, and the stored authorization can be revoked separately. Detect the loss, pause that destination, and tell the owner which sheet stopped and why.
- A sheet has a hard cell limit and will eventually be full. Surface that as its own condition rather than an opaque write failure.
- Dates, currency, and long numeric identifiers are reformatted on entry unless written with an explicit type. An order number arriving as scientific notation is not recoverable from the sheet.
Definition of done
8
Definition of done
8- Spreadsheet, worksheet, and column mapping are chosen explicitly and previewed before the first write.
- Columns are resolved by header at write time, and a missing header stops the write with a named error.
- Keyed destinations update the existing row, and a retried job never produces a duplicate.
- Values that a spreadsheet would evaluate as formulas are neutralized before writing.
- Writes happen in the background, and a form submission succeeds regardless of the provider's availability.
- Revoked access, exhausted quota, and a full sheet each produce a distinct, visible state.
- The feature matches the existing design system.
- No existing functionality is broken.

Contentful Entry Sync
Contentful Entry Sync
Create and update Contentful entries against the connected space, environment, and locale.
What it does
A sync that writes app records into Contentful entries using the connected space's content model and locale configuration.
How it works
- 1 Have the operator select the space, the environment, and the default locale during connection, and store all three, because writing production content into a sandbox environment is an easy and expensive mistake.
- 2 Fetch the content model at connection time and again before each sync run, map app fields to entry fields by their stable identifiers, and validate the value type against the model before attempting the write.
- 3 Write every localized field under an explicit locale rather than relying on whatever the space treats as default, and state clearly which locales the app owns and which it leaves to editors.

Typesense Index Sync
Typesense Index Sync
Keep a search index in step with your records so results stay current and correctly scoped.
What it does
A one-way sync from the app's records into a Typesense collection, with server-enforced tenant filtering and a rebuild path.
How it works
- 1 Identify every model users search today and declare the indexed shape explicitly: the fields people type into, the fields they filter and sort on, and nothing more. Treat a missing or newly added field as absent rather than letting the document fail validation.
- 2 Reuse the app's existing background-job system to push creates, updates, and deletes. Do not index inside the request cycle; a slow or unreachable search service must never make a save fail or hang.
- 3 Build the tenant, workspace, and permission filter on the server at query time and attach it to every search. Do not accept a filter, collection name, or scope value from a client-supplied parameter, because anything the browser can set the browser can change.

Mapbox Geocoding
Mapbox Geocoding
Convert typed locations into coordinates and structured addresses the app can use.
What it does
Forward and reverse geocoding with confirmed matches, controlled result bias, and coordinate precision rules.
How it works
- 1 Separate the two directions explicitly: text to coordinates for entry and search, coordinates to address for a dropped pin or a device location. They take different inputs, carry different confidence, and fail differently.
- 2 Present ambiguous matches as a list the user confirms. Silently taking the first result is how a record ends up in the wrong country with nobody noticing for months.
- 3 Bias results toward a location only when the app genuinely knows one, such as a workspace address or the map viewport the user is already looking at.

It inspects, then implements
Your agent reads your existing app first, then adds the feature to fit it.
Works with your stack
These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
Need it tighter than that? Customize the feature and tell it exactly what you're running.
