Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.00587 |
| Opus 5 | $0.00014 | $0.00293 |
| Sonnet 5 | $0.00005 | $0.00117 |
| Haiku 4.5 | $0.00003 | $0.00059 |
Grade A, and why
Locator Healer Agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Locator Healer Agent
Purpose: Automatically repair broken locators when automation tests fail.
When to Use
Use this skill when:
- A test fails with "element not found" or "element detached" errors
- UI has changed and existing locators no longer work
- After a frontend deployment that modifies DOM structure
Responsibilities
When a locator fails:
- Inspect current DOM or UI hierarchy
- Compare old locator with current page structure
- Identify updated attributes
- Generate a replacement locator
- Re-run test to verify the fix
Detection Strategy
Locator is considered broken when:
- Element not found (NoSuchElementException / TimeoutError)
- Element detached from DOM
- Selector matches zero elements
- Selector matches wrong element (different text/position)
Healing Workflow
Step 1: Analyze the Error
- Read error log to identify which locator failed
- Identify the Page Object file and line number
Step 2: Inspect Current DOM
- Open the page using MCP tools
- Navigate to the same state as the failing test
- Inspect the target area in DOM
Step 3: Find Alternative Locator
Try the following in priority order:
- Accessibility attributes (
aria-label,role) data-testid/data-testid(if stable, not auto-generated)- Semantic locator (Playwright
getByRole,getByLabel) css selector(stable attributes)xpath(relative, not positional)
Step 4: Validate & Replace
- Verify the new locator matches exactly one element
- Verify the element is the correct one (text, position, behavior)
- Replace the broken locator in the Page Object class
- Re-run the test
Difference from Smart Locator Agent
| Aspect | Locator Healer | Smart Locator |
|---|---|---|
| Trigger | Test failure (reactive) | New element (proactive) |
| Input | Broken locator + error log | HTML/DOM element |
| Goal | Fix existing locator | Generate new locator |
| Workflow | Error → Inspect → Replace → Verify | Inspect → Generate → Validate |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Locator Healer Agent is a skill published in the GitHub repository anhtester/antigravity-testing-kit (132 stars, last pushed 1mo ago), licensed MIT. It adds 27 tokens to every session and 587 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
