AWF Integration for Claude Engine

This PR integrates Application-level Firewall (AWF) for the Claude engine following the Copilot pattern. Deprecates Python hooks entirely—AWF is now the sole network restriction mechanism for Claude.

Core Changes

Domain allowlist (domains.go): Added ClaudeDefaultDomains with Anthropic services, GitHub, infrastructure (CRL/OCSP), package managers, Playwright
Firewall support (claude_engine.go): Set supportsFirewall: true, AWF wraps Claude CLI with --tty flag, domain allowlist, required mounts
Default enablement (firewall.go): Added enableFirewallByDefaultForClaude() mirroring Copilot behavior
Observability (compiler_yaml_main_job.go): Added firewall log upload/parsing steps for Claude

Removed (deprecated)

engine_network_hooks.go — Python hook generation
claude_settings.go — Settings file generation for hooks

AWF Command Structure

sudo -E awf \
--tty \
--allow-domains *.githubusercontent.com,anthropic.com,api.anthropic.com,... \
--mount /home/runner/work/... \
--mount /tmp \
--mount /usr/bin/node,/usr/bin/npx \
--mount ~/.npm \
--proxy-logs-dir /tmp/gh-aw/sandbox/firewall/logs \
-- npx @anthropic-ai/claude-code@<version> ...

Behavior

AWF enabled when network.firewall: true is set (or enabled by default when network restrictions present)
Disableable via sandbox.agent: false
Reuses existing parse_firewall_logs.cjs (engine-agnostic)

Merged with main

Resolved merge conflicts in multiple files to incorporate Codex AWF support alongside Claude AWF support:

pkg/workflow/compiler_yaml_main_job.go: Added both Claude and Codex firewall log collection steps
pkg/workflow/domains.go: Added ClaudeDefaultDomains alongside CodexDefaultDomains and merged domain functions
pkg/workflow/domains_test.go: Added tests for both Claude and Codex domain functions
pkg/workflow/firewall.go: Updated comment to include all supported engines (copilot, claude, codex)

Original prompt

Overview

Integrate Application-level Firewall (AWF) for the Claude engine following the Copilot pattern, providing network isolation for Claude Code CLI via domain allowlisting.

User decisions

AWF enabled by default for Claude (like Copilot)
Deprecate Python hooks entirely (AWF is the only network restriction mechanism)
Pre-install Claude CLI during installation steps and mount required binaries (like Copilot)

Phase 1: Core AWF integration

1.1 Add Claude default domains

File:/home/mossaka/developer/gh-aw-repos/gh-aw/pkg/workflow/domains.go
Add after CopilotDefaultDomains:

// ClaudeDefaultDomains are the default domains required for Claude Code CLI authentication and operationvarClaudeDefaultDomains= []string{
"*.githubusercontent.com",
"anthropic.com",
"api.anthropic.com",
"api.github.com",
"api.snapcraft.io",
"archive.ubuntu.com",
"azure.archive.ubuntu.com",
"cdn.playwright.dev",
"codeload.github.com",
"crl.geotrust.com",
"crl.globalsign.com",
"crl.identrust.com",
"crl.sectigo.com",
"crl.thawte.com",
"crl.usertrust.com",
"crl.verisign.com",

"crls.ssl.com",
"files.pythonhosted.org",

"github-cloud.githubusercontent.com",
"github-cloud.s3.amazonaws.com",

"ocsp.identrust.com",
"ocsp.sectigo.com",
"ocsp.ssl.com",
"ocsp.thawte.com",
"ocsp.usertrust.com",
"ocsp.verisign.com",

"security.ubuntu.com",
"sentry.io",
"statsig.anthropic.com",
"ts-crl.ws.symantec.com",
"ts-ocsp.ws.symantec.com",
}

Add helper(s) (pattern: merge defaults + NetworkPermissions, deterministic sort; optionally append host.docker.internal when safe-inputs enabled).

1.2 Enable firewall support in the Claude engine

File:/home/mossaka/developer/gh-aw-repos/gh-aw/pkg/workflow/claude_engine.go
Set supportsFirewall: true in NewClaudeEngine().

Phase 2: Installation steps + hook removal

2.1 Update installation steps

File:.../claude_engine.go
Use base install (secret validation + npm install for @anthropic-ai/claude-code) and, when firewall enabled, append AWF installation step.
Note: remove all Python hook install/config logic.

2.2 Remove hook-related files (cleanup commit after verification)

.../engine_network_hooks.go (delete)
.../claude_settings.go (delete)

Phase 3: AWF-wrapped execution

File:.../claude_engine.go
In GetExecutionSteps():

Build Claude command using npx @anthropic-ai/claude-code@<version> ...
If firewall enabled: wrap command with awf using:
- --tty (required)
- --allow-domains <GetClaudeAllowedDomains...()>
- mounts: workspace, /tmp, gh/yq/date, plus node/npx and npm cache dirs needed for the preinstalled package
- --proxy-logs-dir /tmp/gh-aw/sandbox/firewall/logs
Else: run Claude directly (baseline / sandbox.agent: false)

Phase 4: Observability & log parsing

Reuse existing js/parse_firewall_logs.cjs (engine-agnostic).
Keep Claude parsing via js/parse_claude_log.cjs.
In compiler_yaml_main_job.go, add Claude firewall log upload/parsing steps around the same places as Copilot.

Phase 5: Testing

Add .github/workflows/smoke-claude-firewall.md with firewall enabled and allowed network presets; validate:
- CLI invocation via npx inside AWF
- domain allowlist enforcement
- logs produced + parsed
Update .github/workflows/smoke-claude.md with sandbox.agent: false for comparison.

Phase 6: Default enablement

File:/pkg/workflow/firewall.go
Ensure Claude follows the same “enabled by default” logic as Copilot (e.g., copilot || claude).

Critical files summary

Modify

pkg/workflow/domains.go (ClaudeDefaultDomains + merge helper)
pkg/workflow/claude_engine.go (supportsFirewall, install, exec wrapper)
pkg/workflow/compiler_yaml_main_job.go (log steps)
pkg/workflow/firewall.go (default enablement, if needed)

Create

.github/workflows/smoke-claude-firewall.md

Delete (post-verify)

pkg/workflow/engine_network_hooks.go
pkg/workflow/claude_settings.go

All Claude engine workflows now use minimal AWF mounts: - /tmp:/tmp:rw - ${GITHUB_WORKSPACE}:${GITHUB_WORKSPACE}:rw 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Mount only essential components for Claude CLI: - /usr/local/bin/node (Node.js runtime) - /usr/local/bin/claude (Claude CLI executable) - /usr/local/lib/node_modules/@Anthropic-AI (Claude package only, not all node_modules) This surgical approach provides Claude CLI functionality while minimizing the attack surface compared to mounting all of node_modules, npm, npx, and npm cache. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Instead of mounting /usr/local/bin/claude (which doesn't exist in GitHub Actions), invoke Claude directly: node /usr/local/lib/node_modules/@anthropic-ai/claude-code/cli.js Minimal mounts now: - /usr/local/bin/node (Node.js runtime) - /usr/local/lib/node_modules/@Anthropic-AI (Claude package directory) This approach works regardless of where npm creates the claude binary symlink. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

GitHub Actions' setup-node installs to /opt/hostedtoolcache/node, not /usr/local. Mount this entire directory (read-only) to give AWF container access to: - Node.js runtime - npm and npx - All globally installed packages (including Claude CLI) This pragmatic approach avoids path guessing while keeping the mount read-only. AWF's security value comes from network isolation, not filesystem isolation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Prepend hostedtoolcache node bin directory to PATH before invoking Claude. This ensures the claude command is found inside the AWF container even though GitHub Actions installs it in a non-standard location. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Replace PATH manipulation with npx invocation: - npx --yes @anthropic-ai/claude-code (explicit, clean) - No shell command substitution needed - No PATH exports - More maintainable and explicit about what we're running Mount remains the same (/opt/hostedtoolcache/node) but command is cleaner. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Use the configured Claude version (defaults to 2.0.71) in npx command: - npx --yes @anthropic-ai/claude-code@2.0.71 - Ensures version used matches installed version - Improves security and reproducibility - Version controlled by constants.DefaultClaudeCodeVersion 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

The claudeVersion variable needs to be defined in GetExecutionSteps function, not just GetInstallationSteps. This ensures npx invocation uses the correct pinned version (2.0.71 by default, or custom if configured). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

npx breaks MCP server launching (serena fails to connect). Revert to PATH export approach which keeps environment complete: - export PATH="...hostedtoolcache/node/.../bin:$PATH" && claude - Ensures all npm/node binaries available for MCP server spawning - Mount: /opt/hostedtoolcache/node:ro (read-only, pragmatic) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Resolved merge conflicts: - pkg/workflow/compiler_yaml_main_job.go: Added both Claude and Codex firewall log collection steps - pkg/workflow/domains.go: Added ClaudeDefaultDomains alongside new CodexDefaultDomains and merged domain functions - pkg/workflow/domains_test.go: Added tests for both Claude and Codex domain functions - pkg/workflow/firewall.go: Updated comment to include all supported engines Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

Remove duplicate TestCodexDefaultDomains and TestGetCodexAllowedDomains functions that were accidentally introduced during rebase conflict resolution. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
