Troubleshooting

Can My Agent Write to Google Sheets?

Yes—usually. But only when the connector/auth path is configured correctly. Here’s the fast way to diagnose it.

Community pattern: users ask for Google Sheets writes, the agent says "I need a CLI install," and everyone gets stuck in setup loops.

Short version: don’t assume local CLI is required. First verify connector/auth state, then force a no-install write plan.

What actually blocks Sheets writes

Google connector not installed or not fully authorized.
OAuth completed in one session, but you're testing in another stale session.
Sheet sharing/permissions don’t allow edits for the connected account.
Agent defaults to a developer workflow and suggests CLI unnecessarily.

Use this 4-step recovery flow

1) Force a no-install path

Do not require local CLI tools. Use only headless/container-safe methods. If Google Sheets write is possible, provide exact steps now. If not, explain exactly which capability is missing.

2) Validate connector status in plain language

Before writing anything, state: - Whether my Google connector is available in this session - Which account it is authenticated as - Whether write scope is available - One read test you can run first

3) Run a tiny, reversible write test

Create a test row in sheet [SHEET NAME/URL]: Column A = "heyron-test" Column B = current timestamp Then confirm by reading back the inserted row.

4) If it fails, collect a clean escalation packet

Expected action: write one test row Actual result: [error text] Connector status reported by agent: [paste] Google account used: [email] Sheet URL: [link] Can you read from the sheet in same session? [yes/no]

Important permission check (most-missed step)

Even with a working connector, writes fail if the target sheet isn’t editable by the authenticated Google account.

Open the sheet and check Share settings.
Confirm the connected account has Editor access.
Re-test with a brand-new row, not an overwrite of protected cells.

Avoid this loop: "Agent can read Gmail/Drive so Sheets write must work." Read and write permissions can differ. Always test write explicitly.

Advanced gotchas that look like "write failed"

Wrong tab target: the sheet file is right, but the write is sent to a different worksheet/tab.
Protected ranges: account is an Editor but specific columns/cells are locked.
Header mismatch: automation expects exact column names; renamed headers can cause skipped writes.
Filter/sort confusion: row appears "missing" because filtered view hides it.

Use this verification prompt:

Write to sheet [URL], tab name exactly "[TAB NAME]", append one row with values: A="heyron-verify", B=current timestamp. Then read back the last 3 rows from that same tab and print them verbatim.

Bottom line: treat "install a CLI" as optional unless the agent proves no connector/API path exists. Most users can solve this with connector auth + sheet permissions + explicit tab targeting + a tiny write-readback test.
