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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Output Handling · line 91 Model output is used without validation or sanitization. Unvalidated output injected into downstream contexts (SQL, shell, HTML) enables injection attacks and arbitrary code execution.Fix: Validate and sanitize all model output before using it in downstream contexts. Use parameterized queries for SQL, shell quoting for commands, and HTML encoding for web output.
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 | $0.00078 | $0.05196 |
| Opus 5 | $0.00039 | $0.02598 |
| Sonnet 5 | $0.00016 | $0.01039 |
| Haiku 4.5 | $0.00008 | $0.00520 |
Grade A, and why
mcp-core-best-practices 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 11d 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 — 425 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Alibaba Cloud MCP Core Best Practices
This skill documents the canonical patterns for using the alibabacloud-core MCP
server — the generalized OpenAPI MCP Server Core that covers all Alibaba Cloud
APIs without requiring pre-selection of specific operations.
Available Tools
| Tool | Purpose |
|---|---|
AlibabaCloud___SearchApis |
Natural language search for APIs matching a requirement |
AlibabaCloud___CallCLI |
Execute a single CLI command remotely |
AlibabaCloud___GetApiDefinition |
Get full API definition (params, response, errors) by product/version/name |
AlibabaCloud___ListApis |
List all APIs for a product, optionally filtered |
AlibabaCloud___ListProductRegions |
List regions where a product is available |
AlibabaCloud___GenerateCLICommand |
Generate a CLI command from API definition + parameters |
AlibabaCloud___ListProducts |
List all Alibaba Cloud products |
AlibabaCloud___SearchDocuments |
Search Alibaba Cloud official documentation by keyword, with optional product/language/site filters |
AlibabaCloud___GetDocument |
Get full Markdown content of a document by doc_id (preferred) or URL |
AlibabaCloud___GetDocumentTree |
Browse a product's document directory tree to discover available docs |
AlibabaCloud___GrepDocuments |
Search within a specific product's documents by keyword pattern |
AlibabaCloud___RunScript |
Start a restricted Python task with structured Alibaba Cloud OpenAPI access |
AlibabaCloud___GetTask |
Long-poll a RunScript task until approval, execution, or failure reaches a terminal state |
AlibabaCloud___RunIaC |
Run Terraform / IaC (action=plan/apply/destroy) to provision or tear down a multi-resource stack; plan-before-apply, sync or async, HITL approval |
AlibabaCloud___GetPresignedUrl |
Get a time-limited OSS presigned URL (default upload) + presignToken to feed RunIaC; no credentials exposed |
Standard Workflow
1. API Discovery
When the target API is unknown, use AlibabaCloud___SearchApis with a natural
language description of the requirement. Each query should be granular enough to
map to a single API call.
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.

mcp-core-best-practices is a skill published in the GitHub repository aliyun/alibabacloud-agent-toolkit (21 stars, last pushed today), licensed Apache-2.0. It adds 78 tokens to every session and 5,196 once invoked, about $0.0004 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.
