AWS Cloudformation Task Ecs Deploy Gh

What it does

When your agent uses it

• Building Docker images
• Updating ECS task definitions
• Deploying ECS services
• Integrating with CloudFormation stacks

Example prompts

• “Use the aws-cloudformation-task-ecs-deploy-gh skill to provide patterns to deploy ECS tasks and services with GitHub Actions CI/CD”
• “/aws-cloudformation-task-ecs-deploy-gh”

Requirements

• Docker
• Pre-approved tools (allowed-tools): Read, Write, Bash

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

1. 1Configure AWS Authentication: Set up OIDC provider for GitHub Actions
2. 2Create IAM Roles: Define roles for deployment actions
3. 3Set Up ECR Repository: Create repository with image scanning
4. 4Create ECS Cluster: Define cluster infrastructure
5. 5Configure Task Definition: Set up task and container definitions
6. 6Set Up ECS Service: Configure service with deployment strategy
7. 7Create GitHub Workflow: Define CI/CD pipeline steps
8. 8Configure Secrets: Store credentials securely in GitHub Secrets

What it can do on your machine

Read from SKILL.md and the folder at commit fe73fb3. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Bash

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

AWS Cloudformation Task Ecs Deploy Gh loads about 2.8k tokens when it runs, and up to ~40k if it reads all its reference files. Until then it costs about 147 tokens; SKILL.md has 774 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~147

When it runs · the whole SKILL.md, loaded when a task matches

~2.8k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~40k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

• NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

  allowed-tools: Read, Write, Bash

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Provides patterns to deploy ECS tasks and services with GitHub Actions CI/CD. Use when building Docker images, pushing to ECR, updating ECS task definitions, deploying ECS services, integrating with CloudFormation stacks, configuring AWS OIDC authentication for GitHub Actions, and implementing production-ready container deployment pipelines. Supports ECS deployments with proper security (OIDC or IAM keys), multi-environment support, blue/green deployments, ECR private repositories with image scanning, and CloudFormation infrastructure updates.
