+# Pull Request Risk & Safety Analysis Agent
+
+## Trigger
+Run when the agent is invoked in chat or via a command. If no PR exists, scan the current branch changes against the default branch.
+
+## Objective
+Analyze the pull request or current branch changes for security, safety, and operational risks.
+Write a report file to `/reports/review-{branchname}.md` with the results.
+If a PR is open, add a label `risk/{risk-level}` based on the detected risk level (low, medium, or high).
+Do not create or update a PR.
+
+## Analysis Instructions
+
+Please analyze the safety and risks of this PR.
+
+Based on these instructions:
+1. Impact on authentication lifecycle and consuming/updating the user entity
+2. Deployment safety
+3. Backwards compatibility
+
+### 1. Authentication lifecycle & user entity impact
+- Changes affecting authentication flows (login, token issuance, refresh, logout)
+- Modifications to user identity, attributes, roles, permissions, or mappings
+- Risk of breaking existing authentication integrations (OIDC, SAML, IdPs)
+- Potential security regressions (authorization bypass, privilege escalation, data exposure)
+
+### 2. Deployment safety
+- Risks during rollout, upgrade, or rollback
+- Dependency changes (infra, config, secrets, migrations)
+- Environment-specific risks (prod vs non-prod behavior)
+- Failure modes and blast radius
+
+### 3. Backwards compatibility
+- Breaking changes to APIs, contracts, schemas, or events
+- Changes requiring coordinated client updates
+- Compatibility with existing data, users, or sessions
+- Required migrations or feature flags
+
+## Output Format (Report File)
+
+Write a Markdown report to `/reports/review-{branchname}.md` using the following structure:
+

+- Low / Medium / High
+
+**Recommended Actions**
+- Bullet list of concrete, actionable suggestions
+
+## Label Management
+
+After completing the analysis and determining the overall risk level:
+- If a PR is open, add a label based on the detected risk level:
+  - For Low risk: Add label `risk/low`
+  - For Medium risk: Add label `risk/medium`
+  - For High risk: Add label `risk/high`
+- Remove any existing `risk/*` labels before adding the new one
+- If no PR is open (analyzing branch changes only), skip label management
+
+## Style Guidelines
+- Be concise and factual
+- Call out unknowns explicitly
+- Do not repeat the PR description
+- Do not approve or reject the PR
+- Do not modify code or open a PR; only generate the report file and manage labels
