AWS CLI best practices including pagination control, output formatting, and efficient querying. Use when running AWS CLI commands, querying AWS resources, or automating AWS operations.
AWS CloudWatch dashboard observability patterns including dashboard hierarchy, widget selection, CDK implementation, metric math, alarms, and cross-account monitoring. Use when creating dashboards, setting up observability, or instrumenting workloads with CloudWatch.
Docker image building best practices including multi-stage builds, layer optimization, and security hardening. Use when creating Dockerfiles, optimizing image size, or debugging container builds.
Technical documentation patterns including READMEs, API docs, runbooks, and architecture decision records. Use when writing documentation, creating runbooks, or documenting system architecture.
Git operations, branching strategies, commit conventions, and repository management. Use when working with version control, creating branches, writing commits, or resolving merge conflicts.
Bash and Zsh scripting patterns with built-in logging and non-interactive execution. Use when writing automation scripts, CLI tools, or system administration tasks.

Always use --no-cli-pager for complete results in a single response:
# Good: Complete results
aws ec2 describe-instances --no-cli-pager
aws s3api list-objects-v2 --bucket my-bucket --no-cli-pager
aws iam list-users --no-cli-pager
# Bad: May truncate or require interaction
aws ec2 describe-instances
Only use default pagination when:
Combine --no-cli-pager with --query for efficient data retrieval:
# Running instances only
aws ec2 describe-instances --no-cli-pager \
--query 'Reservations[].Instances[?State.Name==`running`].[InstanceId,InstanceType]'
# Large S3 objects
aws s3api list-objects-v2 --bucket my-bucket --no-cli-pager \
--query 'Contents[?Size>`1000000`].[Key,Size]'
# Specific fields as table
aws ec2 describe-instances --no-cli-pager \
--query 'Reservations[].Instances[].[InstanceId,State.Name,InstanceType]' \
--output table
--output json # Default, full detail
--output table # Human-readable
--output text # Tab-separated, good for scripting
--output yaml # YAML format
# Get account ID
aws sts get-caller-identity --query 'Account' --output text --no-cli-pager
# List all regions
aws ec2 describe-regions --query 'Regions[].RegionName' --output text --no-cli-pager
# Wait for resource
aws ec2 wait instance-running --instance-ids i-1234567890abcdef0
# Dry run (check permissions)
aws ec2 run-instances --dry-run --image-id ami-12345 --instance-type t3.micro
