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 | $0.00000 | $0.00602 |
| Opus 5 | $0.00000 | $0.00301 |
| Sonnet 5 | $0.00000 | $0.00120 |
| Haiku 4.5 | $0.00000 | $0.00060 |
Grade A, and why
azure-cosmosdb-application-developer 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Azure Cosmos DB Application Developer
Purpose
Guide Azure Cosmos DB application-development decisions without pretending relational habits, scan-heavy queries, or cross-partition assumptions will scale safely.
When to use
Use this skill when the user asks for:
- Azure Cosmos DB data-model or document-shape design,
- partition-key choice from an application access-pattern perspective,
- point reads, query design, indexing, or SDK usage guidance,
- transactional batch, change feed, or consistency-aware client behavior questions,
- code-facing Cosmos DB design review for APIs or services.
Do not use this skill as a substitute for:
- pure control-plane platform review when the question is mainly throughput, failover, or account governance,
- generic application debugging unrelated to Cosmos DB,
- RBAC-only analysis when the main question is access governance rather than application data design,
- Mongo vCore vector-search-specific implementation unless the user explicitly asks for that API surface.
Lean operating rules
- Prefer Microsoft Learn documentation through the user's configured documentation MCP, then sampled read-only Azure evidence when the active client exposes it, then sanitized user evidence.
- Separate confirmed facts from inference. If state was not queried or shown, say so.
- Challenge broad scope, vague partition keys, and RU-blind advice.
- Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.
References
Load these only when needed:
- Operations guide — use for service-specific pitfalls, design rules, verification targets, and pushback criteria.
- MCP and evidence path — use when choosing documentation-based evidence, sampled read-only Azure evidence, or sanitized user evidence.
- Safety checklist — use for evidence labels, risk gates, mutation boundaries, approval rules, and credential boundaries.
- Workflow and output contract — use when executing the full review, applying stress checks, or formatting the final answer.
- Official sources — use when you need the detailed Microsoft documentation list or source notes.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

azure-cosmosdb-application-developer is a skill published in the GitHub repository VincentChuWaiChow/vanguard-frontier-agentic (22 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 602 tokens. 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 2026-09-04.
