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 | $0.00336 | $0.00336 |
| Opus 5.5 | $0.00134 | $0.00134 |
| Sonnet 5.5 | $0.00067 | $0.00067 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
cosmosdb-agent-kit GEMINI.md 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 2mo 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.
What it actually says
Azure Cosmos DB Gemini Extension
This extension provides best practice skills for Azure Cosmos DB (NoSQL) — covering data modeling, partition key design, query optimization, SDK usage, indexing strategies, vector search, full-text search, global distribution, security, monitoring, and design patterns.
Installation
Install via the skills CLI:
npx skills add AzureCosmosDB/cosmosdb-agent-kit
Or copy the extension file into your Gemini configuration directory.
Usage
Once installed, the skills are automatically available when Gemini detects tasks related to Azure Cosmos DB. Example prompts:
- "Review my Cosmos DB data model for performance issues"
- "Help me choose a partition key for my e-commerce orders"
- "Optimize this query to reduce RU consumption"
- "Set up vector search on my Cosmos DB container"
- "What security do I need for a new Cosmos DB app?"
Skill Categories
| Priority | Category | Impact |
|---|---|---|
| 1 | Data Modeling | CRITICAL |
| 2 | Partition Key Design | CRITICAL |
| 3 | Query Optimization | HIGH |
| 4 | SDK Best Practices | HIGH |
| 5 | Design Patterns | HIGH |
| 6 | Vector Search | HIGH |
| 7 | Full-Text Search | HIGH |
| 8 | Security | HIGH |
| 9 | Indexing Strategies | MEDIUM-HIGH |
| 10 | Throughput & Scaling | MEDIUM |
| 11 | Global Distribution | MEDIUM |
| 12 | Developer Tooling | MEDIUM |
| 13 | Monitoring & Diagnostics | LOW-MEDIUM |
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.
