On March 30, 2026, the agentic workflow firewall monitored 38 workflow runs across the
github/gh-awrepository. A total of 1,037 network requests were processed, with an overall block rate of 1.16% (12 blocked out of 1,037). The firewall is functioning correctly, enforcing domain allowlists while enabling legitimate AI and development tooling traffic to flow unimpeded.Five unique domains triggered blocks, primarily from AI services (chatgpt.com) and Go package infrastructure (proxy.golang.org, pkg.go.dev) that are not in the current allowlist. GitHub API access (github.com, api.github.com) was also blocked in two workflows that appear to be routing via a non-standard path instead of through the GitHub MCP server.

Request Patterns
The firewall successfully protected 38 workflow runs with 98.84% of traffic flowing freely. The dominant traffic sources were the Anthropic API (213 requests) and GitHub Copilot API (731 requests), confirming standard AI-engine behavior. The 12 blocked requests represent well-functioning policy enforcement.
Top Blocked Domains
The blocked domain distribution is concentrated across 5 domains in 3 categories. The most notable finding is
chatgpt.combeing blocked in 3 separate workflows — this may indicate AI agents attempting to make external LLM calls that should be routed through the configured engine instead. The Go package services (proxy.golang.org, pkg.go.dev) blocks are expected for workflows that don't have Go network access configured.Top Allowed Domains

🟡 Investigate: chatgpt.com Access Attempts
Three separate workflows (
Smoke Codex,Changeset Generator,Schema Feature Coverage Checker) attempted to accesschatgpt.com. This is suspicious as:🔵 Expected: github.com / api.github.com blocks in 2 workflows
Changeset GeneratorandSchema Feature Coverage Checkerare attempting direct GitHub API access. Per the AGENTS.md guidelines, the Copilot engine cannot access api.github.com directly — it must use the GitHub MCP server.tools.github.toolsets: [default]instead of allowing direct GitHub API access via network rules🔵 Expected: Go package service blocks in Dependabot Dependency Checker

These are legitimate Go package services needed for dependency resolution.proxy.golang.org,pkg.go.dev, andsum.golang.orgto the network allowlist for theDependabot Dependency Checkerworkflow if Go package resolution is required✅ No Security Concerns: All other traffic
The remaining 38 workflow runs (1,025 requests) were fully allowed with clean traffic patterns — primarily AI API calls (Copilot, Anthropic, OpenAI) and package registries (NPM, GitHub raw content).
