# Arize Link

Generate deep links to the Arize UI for traces, spans, sessions, datasets, labeling queues, evaluators, and annotation configs.

## When to Use

- User wants a link to a trace, span, session, dataset, labeling queue, evaluator, or annotation config
- You have IDs from exported data or logs and need to link back to the UI
- User asks to "open" or "view" any of the above in Arize

## Required Inputs

Collect from the user or context (exported trace data, parsed URLs):

| Always required | Resource-specific |
|---|---|
| `org_id` (base64) | `project_id` + `trace_id` [+ `span_id`] — trace/span |
| `space_id` (base64) | `project_id` + `session_id` — session |
| | `dataset_id` — dataset |
| | `queue_id` — specific queue (omit for list) |
| | `evaluator_id` [+ `version`] — evaluator |

**All path IDs must be base64-encoded** (characters: `A-Za-z0-9+/=`). A raw numeric ID produces a valid-looking URL that 404s. If the user provides a number, ask them to copy the ID directly from their Arize browser URL (`https://app.arize.com/organizations/{org_id}/spaces/{space_id}/…`). If you have a raw internal ID (e.g. `Organization:1:abC1`), base64-encode it before inserting into the URL.

## URL Templates

Base URL: `https://app.arize.com` (override for on-prem)

**Trace** (add `&selectedSpanId={span_id}` to highlight a specific span):
```
{base_url}/organizations/{org_id}/spaces/{space_id}/projects/{project_id}?selectedTraceId={trace_id}&queryFilterA=&selectedTab=llmTracing&timeZoneA=America%2FLos_Angeles&startA={start_ms}&endA={end_ms}&envA=tracing&modelType=generative_llm
```

**Session:**
```
{base_url}/organizations/{org_id}/spaces/{space_id}/projects/{project_id}?selectedSessionId={session_id}&queryFilterA=&selectedTab=llmTracing&timeZoneA=America%2FLos_Angeles&startA={start_ms}&endA={end_ms}&envA=tracing&modelType=generative_llm
```

**Dataset** (`selectedTab`: `examples` or `experiments`):
```
{base_url}/organizations/{org_id}/spaces/{space_id}/datasets/{dataset_id}?selectedTab=examples
```

**Queue list / specific queue:**
```
{base_url}/organizations/{org_id}/spaces/{space_id}/queues
{base_url}/organizations/{org_id}/spaces/{space_id}/queues/{queue_id}
```

**Evaluator** (omit `?version=…` for latest):
```
{base_url}/organizations/{org_id}/spaces/{space_id}/evaluators/{evaluator_id}
{base_url}/organizations/{org_id}/spaces/{space_id}/evaluators/{evaluator_id}?version={version_url_encoded}
```
The `version` value must be URL-encoded (e.g., trailing `=` → `%3D`).

**Annotation configs:**
```
{base_url}/organizations/{org_id}/spaces/{space_id}/annotation-configs
```

## Time Range

CRITICAL: `startA` and `endA` (epoch milliseconds) are **required** for trace/span/session links — omitting them defaults to the last 7 days and will show "no recent data" if the trace falls outside that window.

**Priority order:**
1. **User-provided URL** — extract and reuse `startA`/`endA` directly.
2. **Span `start_time`** — pad ±1 day (or ±1 hour for a tighter window).
3. **Fallback** — last 90 days (`now - 90d` to `now`).

Prefer tight windows; 90-day windows load slowly.

## Instructions

1. Gather IDs from user, exported data, or URL context.
2. Verify all path IDs are base64-encoded.
3. Determine `startA`/`endA` using the priority order above.
4. Substitute into the appropriate template and present as a clickable markdown link.

## Troubleshooting

| Problem | Solution |
|---|---|
| "No data" / empty view | Trace outside time window — widen `startA`/`endA` (±1h → ±1d → 90d). |
| 404 | ID wrong or not base64. Re-check `org_id`, `space_id`, `project_id` from the browser URL. |
| Span not highlighted | `span_id` may belong to a different trace. Verify against exported span data. |
| `org_id` unknown | `ax` CLI doesn't expose it. Ask user to copy from `https://app.arize.com/organizations/{org_id}/spaces/{space_id}/…`. |
