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 | $0.00063 | $0.02885 |
| Opus 5 | $0.00032 | $0.01443 |
| Sonnet 5 | $0.00013 | $0.00577 |
| Haiku 4.5 | $0.00006 | $0.00288 |
Grade A, and why
prior-auth-review-skill 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.

Prior Authorization Review Skill
Overview
This skill automates the payer review process for prior authorization (PA) requests. It processes clinical documentation, validates medical necessity against coverage policies, and generates authorization decisions with supporting rationale.
Target Users: Health insurance payer organizations (Medicare Advantage, Commercial, Medicaid MCOs)
Value Proposition: Reduce PA review time from 30-60 minutes to under 5 minutes. Enable auto-approval for 40-60% of clear-cut cases.
Architecture
This skill uses a simplified 2-subskill workflow:
Subskill 1: Intake & Assessment
↓ (validates data, extracts clinical info, assesses medical necessity)
Subskill 2: Decision & Notification
↓ (generates auth decision with provider notification)
ONLY REVIEW THE SUBSKILL FILES WHEN THEY ARE NEEDED, DONT PRE-READ THE WHOLE SKILL ON BOOTUP
Output: Authorization Decision Package
Waypoint Files

├── assessment.json # Subskill 1 output (consolidated)
└── decision.json # Subskill 2 output (final decision)
Prerequisites
Required MCP Servers
This skill requires 3 healthcare MCP connectors:
- CMS Coverage MCP Connector - Medicare coverage policies (NCDs, LCDs)
- ICD-10 MCP Connector - Diagnosis code validation and lookup
- NPI MCP Connector - Healthcare provider verification via NPPES
For detailed tool usage, parameters, and CMS web resources, see references/01-intake-assessment.md.
MCP Invocation Notifications
During execution, the skill displays notifications before and after each MCP connector call:
- Before: "Verifying provider credentials via NPI MCP Connector..."
- After: "NPI MCP Connector completed successfully - Provider verified: Dr. [Name]"
- Before: "Validating diagnosis codes via ICD-10 MCP Connector..."
- After: "ICD-10 MCP Connector completed successfully - [N] codes validated"
- Before: "Searching coverage policies via CMS Coverage MCP Connector..."
- After: "CMS Coverage MCP Connector completed successfully - Found policy: [Policy ID]"
- Before: "Validating procedure codes via CMS Fee Schedule..."
- After: "CPT/HCPCS codes validated via CMS Fee Schedule - [N] codes checked"
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.

prior-auth-review-skill is a skill published in the GitHub repository Agent-Threat-Rule/agent-threat-rules (389 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 2,885 once invoked, about $0.0003 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 2026-09-05.
