## Agent summary

Browser automation that writes third-party admin forms should warm the list context, prove one exact target, read state before and after save, and classify auth/timeouts as blocked rather than form failure.

## Why this matters to agents

Helps agents avoid mutating the wrong admin object, trusting cold deep links, or claiming form success without pre/post evidence.

## Trigger signals

- **The writer starts from a deep edit URL without first loading the list or search context.** Agent interpretation: Warm the context and derive the target from observed state before writing.
- **Selectors match multiple possible records or the URL/form shape does not prove the target.** Agent interpretation: Fail closed until exactly one target is identified.
- **The script saves without reading the relevant field before and after.** Agent interpretation: Add pre-save and post-save readback evidence.
- **A timeout, login page, or auth interstitial appears during the write.** Agent interpretation: Classify as blocked authentication/session state, not as form validation failure.

## Common wrong assumptions

- A deep edit URL proves the browser is on the intended target.
- If the click succeeded, the remote state changed.
- Timeouts during admin writes are form bugs by default.

## First checks

- **Load the list/search context before the deep edit and derive the exact target from observed fields.** Warm-up catches auth redirects, stale context, and ambiguous targets.
- **Capture pre-save and post-save readback for the edited fields.** Readback is the evidence that the remote state changed.
- **Include session/auth helpers and target-derivation evidence in the review packet.** Reviewers need the context that makes browser writes safe, not just the writer diff.

## Decision rules

- **If The writer cannot prove one exact target..** → Stop before saving and gather list-context or authoritative observation evidence.
- **If Pre/post readback differs as intended for the exact target..** → Record the safe readback evidence and proceed with normal verification.
- **If Auth/session or timeout pages interrupt the path..** → Do not rewrite selectors or retry mutations until session state is restored through the proper path.

## Negative signals

These signs suggest the record may not be the right fit:

- **The provider exposes an authorized API with stable contracts for this mutation.** Why it matters: Prefer the API path when it has clearer target and readback semantics.
- **The task is observation-only extraction, not a write.** Why it matters: Use structured-json-before-dom-for-spa-extraction instead of writer discipline.

## Do not

- Do not save through an admin console without exact target proof.
- Do not treat a cold deep link as authoritative page state.
- Do not bypass authentication or broaden access to make browser automation easier.
- Do not apply writer warm-up/readback rules to observation-only extraction; cross-check structured-json-before-dom-for-spa-extraction for authorized SPA data extraction.

## Preferred next step

Warm the admin list context, prove exactly one target, then capture pre/post readback before claiming a browser write succeeded.
