Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

zia-investigate-url-category 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 12d 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.

ZIA: Investigate URL Category

Keywords

url category, where is category used, url filtering, category lookup, url policy, category impact, url rules, which rules use category, url category audit, policy investigation

Overview

Investigate where a specific URL or URL category is referenced across all ZIA security policies. This skill queries URL filtering rules, DLP web rules, SSL inspection rules, and cloud firewall rules to build a complete picture of how the category affects traffic and users.

Use this skill when: An administrator wants to understand the policy impact of a URL category, check which rules reference a specific category, or determine what happens when a user tries to access a URL in that category.


Workflow

Follow this 5-step process to investigate a URL category.

Step 1: Identify the URL Category

Determine whether the admin is asking about a specific URL or a named category.

If given a URL, look it up first:

zia_url_lookup(urls=["example.com"])
```text

This returns the URL's category classification (e.g., "SOCIAL_NETWORKING", "STREAMING_MEDIA").

**If given a category name**, list categories to find the exact ID. Narrow the
request — unfiltered, this returns every category in the tenant:

```text
zia_list_url_categories(custom_only=True, search="partner")
```text

`custom_only=True` is a real API filter and the right first move whenever the
admin is asking about a category they created. `search` matches the configured
name; if it comes back empty, drop it and match on the `id` instead.

Find the category in the results and note its `id` (e.g., "CUSTOM_01",
"SOCIAL_NETWORKING"). By default the listing reports how many URLs each category
holds, not the URLs themselves.

To see the URLs, `superCategory` and the rest of the definition, fetch the
category itself:

```text
zia_get_url_category(category_id="<category_id>")
```text

#### Present Initial Findings

```text
URL Category Identified:

**Category:** Social Networking
- ID: SOCIAL_NETWORKING
- Super Category: Entertainment & Recreation
- Type: Built-in

Now searching across all policy rule types...
