Code review

Found 1 issue:

Unresolved merge conflict marker (=======) in README.md between the aws-amplify MCP Servers section and the migration-to-aws section. This will break the rendered documentation and indicates the branch has conflicts that need to be resolved before merging. The PR also shows mergeable: CONFLICTING status.

           ## migration-to-aws

SKILL.md tells users to "come back and start a new conversation" after configuring AWS credentials (line 45). This is unnecessarily disruptive and not enforceable -- the agent can re-run the prerequisite check in the same session. Consider changing to: "Re-run the prerequisite check script to verify your credentials, then continue."

agent-plugins/plugins/aws-amplify/skills/amplify-workflow/SKILL.md

Lines 40 to 46 in ee2e90a

    
           **Quick options:** 
        
           - Run `aws configure` to set up access keys 
        
           - Run `aws sso login` if using AWS IAM Identity Center 
        
           Once your credentials are configured, **come back and start a new conversation** to continue building with Amplify. 
        
           ```

SKILL.md is missing an explicit ## Defaults section. All other plugins include one (DESIGN_GUIDELINES says "All defaults explicitly specified"). The amplify workflow has implicit defaults (phase ordering, framework choices, deployment targets) that should be documented with override syntax. See deploy-on-aws SKILL.md for reference.

https://github.com/awslabs/agent-plugins/blob/ee2e90a81dd83769842c9b49c83dcdd638af95f1/plugins/aws-amplify/skills/amplify-workflow/SKILL.md

prereq-check.sh uses aws sts get-caller-identity (line 35) but AWS CLI is not listed as a prerequisite. The script checks Node.js, npm, and AWS credentials -- but if aws is not installed, the credentials check fails with a confusing error rather than a clear "AWS CLI not found" message. Consider adding an explicit AWS CLI check to the script and documenting it as a prerequisite.

agent-plugins/plugins/aws-amplify/skills/amplify-workflow/scripts/prereq-check.sh

Lines 34 to 36 in ee2e90a

    
           # AWS credentials configured 
        
           check "AWS credentials" bash -c 'AWS_PAGER="" aws sts get-caller-identity --query Account --output text'

Code review

All 4 issues from the previous review have been addressed:

Merge conflict resolved (PR is now mergeable)
"Start new conversation" replaced with re-run prerequisite check flow
## Defaults section added to SKILL.md
AWS CLI check added to prereq-check.sh

One remaining item: the plugin is missing a plugins/aws-amplify/README.md. DESIGN_GUIDELINES requires this file with the following sections:

Overview - 1-2 sentence plugin purpose
Skills - List of included skills with descriptions
MCP Servers - Required servers and what they provide
Installation - claude plugin install command
Examples - 3-5 concrete usage examples

Keep under 300 lines. See plugins/migration-to-aws/README.md for reference.
