## Short answer

**Can Google Antigravity help me write an X post from an agent test run?**

Yes, once Tareno is registered as an MCP server in Antigravity. It can take the notes and screenshots you export from a session, write a post of up to 280 characters and store it as a draft through Tareno. No client test with Antigravity has been completed on our side, so published guides define the setup. You approve in Tareno.

Teams that let an agent click through their web app end up with something worth showing: a sequence of screenshots that proves the sign-up flow works, or a failure that was caught before a customer saw it. Sharing it on X is a small act of credibility, if the post says what was tested and what was not. Antigravity produces the notes and screenshots inside the Agent Manager, and Tareno turns the ones you choose into a draft. This page follows a small SaaS team through that routine, with the connection steps that published guides describe, and the caution that an agent's test run is evidence of what it tried, not a guarantee.

## Example: a SaaS team shares a checked sign-up flow

Imagine a team that asked Antigravity to walk through its new sign-up flow on three screen sizes. The developer exports the run's notes and the four screenshots she wants to show, and uploads the screenshots to the Tareno library. In Antigravity she asks for a post that says what was tested, one thing that broke and was fixed, and what was not tested. Antigravity writes 250 characters, adds a line that mobile Safari was outside the run, and finds the screenshots with `list_media`. She reads the post, checks that no test account email appears in the images, and saves it with `create_drafts` before requesting a Wednesday slot.

## Step by step

1. **Find the raw MCP file.** The route that published guides describe runs through the Agent window menu to Manage MCP Servers and its raw config view. Menu names have moved between releases, so match them to the version you have installed.
2. **Register the hosted endpoint.** Under mcpServers, add Tareno with its hosted address. Current Antigravity docs specify serverUrl for remote servers and also accept url; the legacy httpUrl field is not supported. If nothing appears, compare the entry with the docs for your Antigravity surface and version.
3. **Sign in and try a harmless call.** Approve the browser prompt, reload the server list and request `list_accounts`. Seeing your X account proves the link; an empty answer usually means the account is not yet connected inside Tareno.
4. **Export the notes and choose the screenshots.** Export the run's notes and pick the screenshots that show the flow. Remove images that show real email addresses or tokens before you upload them to the library.
5. **Write what was tested and what was not.** Ask Antigravity for a post within 280 characters that names the flow, one defect found and what the run did not cover. A test post that lists only successes is marketing.
6. **Save, request and approve.** Antigravity finds the images with `list_media` and saves the post through `create_drafts`. Give a day, a time and an IANA time zone, and approve the pending request in the Tareno dashboard.

## Prompts to copy

### Summarize the run honestly

```text
Read the exported notes from the sign-up flow run and list what was tested, what failed and was fixed, and what the run did not cover, such as browsers or screen sizes. Do not claim more than the notes show, and mark anything you inferred.
```

### Check the screenshots

```text
Use Tareno to look up the screenshots named [signup-1 to signup-4] in my media library. Tell me which appears out of order, then list anything visible in the images that I should remove before they are public, such as email addresses or test tokens.
```

### Write the post

```text
Write an X post within 280 characters that says the sign-up flow was run on three screen sizes, names the one defect that was fixed and states one thing the run did not cover. Use first person plural and no hashtags, and give me the character count.
```

### Save the draft

```text
Use Tareno to confirm the X account [handle] and save the approved text with the four screenshots as a draft. Give me the draft ID and the image order, and wait for my day and time zone before asking for any slot.
```

## X in Tareno

- X allows up to four photos in a post, which fits a four-step flow exactly, and Tareno's configuration for X sets the same limit.
- Tareno's configuration for X allows 280 characters, so the post can say what was tested and what was not, but not list every screen size.
- Tareno does not read posts or replies on X, so Antigravity cannot see whether the post prompted questions or bug reports.
- Tareno saves single posts for X, so a step-by-step walkthrough as a thread has to be written by hand on X.

Official rules ([X API documentation: create a post](https://docs.x.com/x-api/posts/creation-of-a-post), checked 2026-10-24):

- A post may include up to 4 photos, 1 animated GIF or 1 video.
- The allowed video length depends on the posting account, not on the API plan: 20 minutes and 8 GB by default, 125 minutes and 16 GB with X Premium or verified status. Tareno's configuration for X stops at 140 seconds.
- Quote-posting through the API requires an Enterprise plan and is not available on self-serve tiers.

## Mistakes to avoid

- Leaving real data in a screenshot. Check email addresses, tokens and customer names in every image.
- Presenting an agent's pass as a guarantee. Say what was not covered.
- Editing the raw config with the wrong key. If no tools appear, check the field names in Tareno's documentation before Antigravity's.
- Signing in on one surface only. Google reports separate tokens per surface, so each one may need its own approval.

## What does not work

- Antigravity cannot judge whether an image shows private data, so a person looks at every screenshot before it is uploaded.
- It cannot read replies or bug reports under the post, because Tareno does not expose replies for X.
- It cannot send anything to X on its own, because every time request stops at your approval in the dashboard.

## Frequently asked questions

### Is a test run enough evidence to post about?

It shows what the agent tried and saw, not what every user will meet. Post what the notes support, add one thing the run did not cover, and keep screenshots free of real addresses and tokens.

### What if the Tareno tools never appear in Antigravity?

Compare the key names in your raw config with the guides and the Remote MCP setup page, since a wrong key can fail silently. We have not tested every Antigravity version ourselves, so treat that report as a lead.

### Why did Tareno ask me to sign in again?

Google's codelab says tokens are not shared between Antigravity surfaces such as the IDE and the command line. Signing in once per surface is expected, and nothing in Tareno needs changing.

### Should a test post say what failed?

Yes, and what was not tested. A post that lists one fixed defect and one limit is more believable than one that lists only passes, and it fits in 280 characters if you keep it to those two things.

### How many screenshots fit in the post?

Up to four photos on X, according to its API documentation and Tareno's configuration. Pick the four that show the sequence in order, and check each for private data.

### Can Antigravity send the post to X itself?

No. Each time request is held in Tareno until you approve it in the dashboard, and from Antigravity you can only see that it is waiting. Nothing leaves for X before that approval.

## Tareno tools used

- `list_accounts`
- `list_media`
- `create_drafts`

Approval model: Tareno saves drafts directly. Scheduling, publishing, edits to scheduled posts and deletions become pending actions that a person approves in the Tareno dashboard; no agent can approve them.
