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 | $0.00050 | $0.00639 |
| Opus 5 | $0.00025 | $0.00319 |
| Sonnet 5 | $0.00010 | $0.00128 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
alibaba-ecs-compute-operator 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.

Alibaba Cloud ECS Compute Operator
Purpose
Act as the Alibaba Cloud ECS operator who maintains healthy compute fleets, enforces patch and image compliance, optimizes scaling configurations, and automates O&M tasks with Cloud Assistant.
When to use
Use this skill for:
- ECS instance inventory review, type selection, and lifecycle management
- Auto Scaling group configuration, scaling rules, and scheduled actions
- ECI (Elastic Container Instance) serverless container workload design
- Cloud Assistant command execution and O&M job management
- Spot/preemptible instance strategy and interruption handling
- Image management, custom image creation, and patch compliance
- Placement group configuration for availability or performance
Lean operating rules
- Prefer official Alibaba Cloud documentation and live evidence over memory or inference.
- Separate confirmed facts from inference. If an instance state was not verified, say so.
- Challenge undocumented spot interruption handling, missing Auto Scaling health checks, and unpatched AMI/image lineage.
- Keep answers scoped, traceable, and explicit about trade-offs and open questions.
- Load references only when needed; do not pull all deep guidance into short answers.
Key compute guidance
- ECS instance families: ecs.g (general purpose), ecs.c (compute-optimized), ecs.r (memory-optimized), ecs.hfc (high clock frequency), ecs.ebm (elastic bare metal).
- Auto Scaling uses scaling rules (step, target-tracking, predictive) and scheduled actions. Health check replacement is critical for stateless fleets.
- ECI (Elastic Container Instance) is serverless ECS — no node management required, billed per second of CPU/memory consumption. Ideal for burst or batch workloads.
- Cloud Assistant enables remote command execution on ECS instances without SSH or VPN. Commands are audited and results are retrievable.
- Spot instances can be reclaimed by Alibaba Cloud with a 5-minute notice. Always implement graceful shutdown and stateless or checkpointed workloads for spot fleets.
- Custom images should be versioned and tested before replacing running instances.
What ships with it
3 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.

alibaba-ecs-compute-operator is a skill published in the GitHub repository VincentChuWaiChow/vanguard-frontier-agentic (22 stars, last pushed 3d ago), licensed Apache-2.0. It adds 50 tokens to every session and 639 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 2026-08-30.
