 # Claude Code Action
 
-A general-purpose [Claude Code](https://claude.ai/code) action for GitHub PRs and issues that can answer questions and implement code changes. This action intelligently detects when to activate based on your workflow context—whether responding to @claude mentions, issue assignments, or executing automation tasks with explicit prompts. It supports multiple authentication methods including Anthropic direct API, Amazon Bedrock, Google Vertex AI, and Microsoft Foundry.

+## Network Restrictions
+
+For enhanced security, you can restrict Claude's network access to specific domains only. This feature is particularly useful for:
+
+- Enterprise environments with strict security policies
+- Preventing access to external services
+- Limiting Claude to only your internal APIs and services
+
+When `experimental_allowed_domains` is set, Claude can only access the domains you explicitly list. You'll need to include the appropriate provider domains based on your authentication method.
+
+### Provider-Specific Examples
+
+#### If using Anthropic API or subscription
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # Or: claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
+    experimental_allowed_domains: |
+      .anthropic.com
+```
+
+#### If using AWS Bedrock
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    use_bedrock: "true"
+    experimental_allowed_domains: |
+      bedrock.*.amazonaws.com
+      bedrock-runtime.*.amazonaws.com
+```
+
+#### If using Google Vertex AI
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    use_vertex: "true"
+    experimental_allowed_domains: |
+      *.googleapis.com
+      vertexai.googleapis.com
+```
+
+### Common GitHub Domains
+
+In addition to your provider domains, you may need to include GitHub-related domains. For GitHub.com users, common domains include:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    experimental_allowed_domains: |
+      .anthropic.com  # For Anthropic API
+      .github.com
+      .githubusercontent.com
+      ghcr.io
+      .blob.core.windows.net
+```
+
+For GitHub Enterprise users, replace the GitHub.com domains above with your enterprise domains (e.g., `.github.company.com`, `packages.company.com`, etc.).
+
+To determine which domains your workflow needs, you can temporarily run without restrictions and monitor the network requests, or check your GitHub Enterprise configuration for the specific services you use.

-## Structured Outputs
-
-Get validated JSON results from Claude that automatically become GitHub Action outputs. This enables building complex automation workflows where Claude analyzes data and subsequent steps use the results.
-
-### Basic Example
-
-```yaml
-- name: Detect flaky tests
-  id: analyze
-  uses: anthropics/claude-code-action@v1
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    prompt: |
-      Check the CI logs and determine if this is a flaky test.
-      Return: is_flaky (boolean), confidence (0-1), summary (string)
-    claude_args: |
-      --json-schema '{"type":"object","properties":{"is_flaky":{"type":"boolean"},"confidence":{"type":"number"},"summary":{"type":"string"}},"required":["is_flaky"]}'
-
-- name: Retry if flaky
-  if: fromJSON(steps.analyze.outputs.structured_output).is_flaky == true
-  run: gh workflow run CI
-```
-
-### How It Works
-
-1. **Define Schema**: Provide a JSON schema via `--json-schema` flag in `claude_args`
-2. **Claude Executes**: Claude uses tools to complete your task
-3. **Validated Output**: Result is validated against your schema
-4. **JSON Output**: All fields are returned in a single `structured_output` JSON string
-
-### Accessing Structured Outputs
-
-All structured output fields are available in the `structured_output` output as a JSON string:
-
-**In GitHub Actions expressions:**
-
-```yaml
-if: fromJSON(steps.analyze.outputs.structured_output).is_flaky == true
-run: |
-  CONFIDENCE=${{ fromJSON(steps.analyze.outputs.structured_output).confidence }}
-```
-
-**In bash with jq:**
-
-```yaml
-- name: Process results
-  run: |
-    OUTPUT='${{ steps.analyze.outputs.structured_output }}'
-    IS_FLAKY=$(echo "$OUTPUT" | jq -r '.is_flaky')
-    SUMMARY=$(echo "$OUTPUT" | jq -r '.summary')
-```
-
-**Note**: Due to GitHub Actions limitations, composite actions cannot expose dynamic outputs. All fields are bundled in the single `structured_output` JSON string.
-
-### Complete Example
-
-See `examples/test-failure-analysis.yml` for a working example that:
-
-- Detects flaky test failures
-- Uses confidence thresholds in conditionals
-- Auto-retries workflows
-- Comments on PRs

 ## Ways to Tag @claude
 
 These examples show how to interact with Claude using comments in PRs and issues. By default, Claude will be triggered anytime you mention `@claude`, but you can customize the exact trigger phrase using the `trigger_phrase` input in the workflow.
