AWS IAM
Independent PiSkill directory guide. The original skill remains hosted by AWS Agent Toolkit.
What is AWS IAM?
Provides verified IAM guidance for policy evaluation, trust relationships, least-privilege role creation, STS sessions, condition operators, and common security edge cases.
What does AWS IAM do?
AWS IAM is an AWS Agent Toolkit skill for reasoning about identity, permissions and policy behavior on AWS. It helps design least-privilege roles and policies, understand trust relationships and STS sessions, and troubleshoot why a principal is or is not authorized.
Who is AWS IAM best for?
- AWS developers designing least-privilege access
- Security teams reviewing IAM policies
- Engineers troubleshooting AssumeRole or permission failures
- Projects that need clearer trust and identity boundaries
Common use cases
- Create or review an IAM role and trust policy
- Explain why an AWS request is denied
- Design least-privilege access for an application
- Review condition operators and cross-account assumptions
How does AWS IAM work?
The skill separates identity policies, resource policies, trust relationships and session context, then applies AWS policy-evaluation logic to the requested scenario. It uses that model to propose least-privilege changes or explain why an authorization path succeeds or fails.
Key benefits
- Improves reasoning about complex AWS permission chains
- Keeps least privilege as a design goal
- Useful for both implementation and troubleshooting
- Helps distinguish trust policy problems from permission policy problems
Things to know
- AWS authorization can involve organization policies, permission boundaries and service-specific rules beyond one IAM document
- Generated policies should be tested in the target account
- Security-sensitive access changes still require owner review
