name: specialist-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. risk_tier: L2 metadata: internal: true triggers: keywords: - testid inserter - insert test ids - close selector gaps - add data-testid - selector gaps

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, Semantics(identifier:), .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.
