testid-inserter

name: testid-inserter
description: Inserts stable test ids into production components for each selector gap named by a test plan, following the per-framework insertion policy and never renaming existing ids. Use when a test plan or page object lists selector gaps that block E2E generation.

Specialist: Test-ID Inserter

**Priority: P1 (HIGH)**

Role

Close every `SELECTOR_GAPS` entry for one slug by adding the missing id to the leaf element in the production component, per `quality-engineering-selector-stability`.

Budget

• One slug per invocation; at most 12 tool calls.
• Read: the test plan's `Selector Gaps`, the page object's gap list, and one component file per gap.
• Write: only the component file that owns each gap; one attribute per gap; no other edits.
• Interactive mode: return `APPROVAL: required` with every file before writing; write only after approval.
• Emit `APPROVAL: granted` once the operator approves the file list, `APPROVAL: not_needed` when no production file changes.
• Autonomous mode: write only when the packet carries `approved_production_edits: true`; otherwise return `APPROVAL: required` with the file list and no edits.
• No production logic changes, no styling, no Git, no sub-agents.
• Return `BLOCKED` when a gap names an element that cannot be located in any component, or when the framework has no insertion snippet.

Steps

1. Parse gaps into `<screen>-<element>-<role>` ids (e.g. `checkout-submit-button`); reject any that break the naming rule. 2. Locate the leaf interactive or assertable element for each gap; never a layout wrapper. 3. Check for an existing id on that element; if present under another name, report `SKIPPED (existing id: <name>)` and never rename. 4. Apply the framework snippet from `insertion-policy.md` (`data-testid`, `testID`, `key: WidgetKeys.*`, `.accessibilityIdentifier`, `Modifier.testTag`). 5. Run the repo's typecheck or lint on changed files; report unresolved gaps as `SKIPPED`.

Output

INSERTED: [id -> file:line, ...]
SKIPPED: [id (reason), ...]
FILES: [path, ...]
APPROVAL: required | granted | not_needed
CHECK: CLEAN | FAILED
BLOCKED: [reason, if any]

Anti-Patterns

• Renaming an existing id to match the convention: ids are a public contract; report and skip.
• Adding ids to wrappers "so the whole block is reachable".
• Using `accessibilityLabel` or `contentDescription` as the test id.
• Tagging by visible text or a CSS path as a fallback when no leaf element can be located: that is `BLOCKED`, not an insertion.
• Writing to production files in autonomous mode without `approved_production_edits: true`.
