🔥 Executive Summary

This report covers firewall activity for the 24-hour period ending 2026-09-24. Across 50 distinct workflows and 201 firewall-enabled workflow runs (103 run summaries were skipped due to missing/malformed data or no firewall analysis present), the fleet-wide firewall monitored 15,689 network requests. The vast majority of traffic was allowed (98.4%), with a small but consistent stream of blocked requests concentrated on a handful of domains — most notably registry.npmjs.org (the bare, non-:443 variant), which accounted for nearly all blocked traffic and was driven almost entirely by a single workflow, Matt Pocock Skills Reviewer. No policy_analysis data was present in any of the cached run summaries this period, so rule-level attribution (Section 4) is omitted.

📊 Key Metrics

• Total network requests monitored: 15,689
• ✅ Allowed: 15,437
• 🚫 Blocked: 252
• Block rate: 1.61%
• Total unique blocked domains: 3

Terminology Note: Allowed requests successfully reached their destination; blocked requests were prevented by the firewall. A 0% block rate with listed blocked domains indicates domains that would be blocked if accessed, but weren't actually accessed during this period.

🚫 Top Blocked Domains

Domain	Blocked Count	Workflows	Category
registry.npmjs.org	247	Daily Go Test Parallelizer, Impeccable Skills Reviewer, Matt Pocock Skills Reviewer, Slide Deck Maintainer	Development Services (npm registry, non-TLS port variant)
clients2.google.com	4	Daily Model Inventory Checker, Slide Deck Maintainer, Smoke Copilot	Other (Google update/telemetry service)
codeload.github.com	1	Matt Pocock Skills Reviewer	Development Services (GitHub archive downloads)

Note: chart generation via the firewall-chart-generator sub-agent failed (400 model "gpt-5.4-mini" is not accessible via the /chat/completions endpoint), so trend charts are omitted from this report.

🛡️ Security Recommendations

• Allowlist candidate — registry.npmjs.org (plain, non-:443): The TLS-secured registry.npmjs.org:443 variant is already allowed and heavily used (350 requests fleet-wide, 259 in Matt Pocock Skills Reviewer alone) with zero blocks. The plain-port variant is blocked 100% of the time (247 hits), almost certainly representing redirects, HTTP-to-HTTPS upgrade attempts, or an npm client probing both variants — this is expected/benign firewall behavior, not a workflow misconfiguration. No action needed unless the workflow specifically requires plaintext npm access (it should not).
• clients2.google.com: Blocked in 3 workflows (Daily Model Inventory Checker, Slide Deck Maintainer, Smoke Copilot) with very low volume (4 total). This is a Google Chrome/Android component-update pinger, not required for any of these workflows' stated purposes — safe to leave blocked; no allowlist change recommended.
• codeload.github.com (plain, non-:443): Single blocked hit in Matt Pocock Skills Reviewer, while the :443 variant is allowed and used. Same pattern as npmjs — plaintext variant correctly blocked; TLS variant already permitted for GitHub archive/tarball downloads.
• No suspicious/anomalous domains observed: All blocked domains are recognizable, non-malicious infrastructure (npm registry, Google update service, GitHub codeload). No indicators of exfiltration or unexpected external endpoints.
• Workflows to review for network permission tuning: None require urgent changes — blocked traffic is low-volume and represents expected plaintext/TLS redirect noise rather than functional breakage. If Matt Pocock Skills Reviewer begins showing failed npm installs, verify it uses HTTPS npm registry URLs exclusively.
• Policy rule attribution unavailable: No policy_analysis data was present in any cached run this period, so rule-level hit/effectiveness analysis (Section 4) could not be produced. Consider enabling policy analysis capture in the firewall config if per-rule visibility is desired for future reports.

Warning

Firewall blocked 1 domain

The following domain was blocked by the firewall during workflow execution:

• o205451.ingest.us.sentry.io

To allow these domains, add them to the network.allowed list in your workflow frontmatter:

network:
  allowed:
    - defaults
    - "o205451.ingest.us.sentry.io"

See Network Configuration for more information.
