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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00105 | $0.02713 |
| Opus 5 | $0.00053 | $0.01357 |
| Sonnet 5 | $0.00021 | $0.00543 |
| Haiku 4.5 | $0.00011 | $0.00271 |
Grade A, and why
zia-investigate-sandbox 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 Sandbox
Keywords

Overview
Investigate ZIA Sandbox file analysis results and security policy enforcement issues. This skill combines API-driven sandbox inspection (reports, quota, behavioral analysis) with runbook-guided troubleshooting for Malware Protection, Advanced Threat Protection (ATP), and Sandbox policies.
Use this skill when: An administrator reports files being unexpectedly blocked or allowed, files stuck in quarantine, sandbox not analyzing files, missing Patient 0 alerts, or needs to verify a sandbox verdict for a specific file hash.
Workflow
Step 1: Gather Issue Details
Collect from the administrator:
Required:
- Symptom: file blocked, file allowed unexpectedly, file stuck in quarantine, sandbox not analyzing
- File MD5 hash (if available from Web Insights logs)
- URL or domain where the file was downloaded from
Helpful:
- Policy Action from Web Insights logs (e.g., "Sandbox Block", "Quarantined", "Allowed")
- Threat Super Category from Web Insights logs (e.g., "Sandbox", "Virus", "Malware Protection")
- Blocked Policy Type (e.g., "Sandbox", "Malware Protection", "Advanced Threat Protection")
- File type and size
- Sandbox subscription level (Basic vs Advanced)
Step 2: Determine the Security Control Involved
The Blocked Policy Type in Web Insights logs identifies which security control is responsible:
| Blocked Policy Type | Security Control | API Tools Available? |
|---|---|---|
| Sandbox | ZIA Sandbox | Yes -- full API investigation |
| Malware Protection | ZIA Malware Protection | No API -- advisory guidance only |
| Advanced Threat Protection | ZIA ATP | No API -- advisory guidance only |
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.

zia-investigate-sandbox is a skill published in the GitHub repository zscaler/zscaler-mcp-server (50 stars, last pushed 4d ago), licensed MIT. It adds 105 tokens to every session and 2,713 once invoked, about $0.0005 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.
