Executive Summary

AgentRx analyzed 20 recent workflow runs (last ~24h, 2.4 cumulative hours, $18.45). 18/20 runs completed; 2 had errors (Static Analysis Report, Step Name Alignment, both on the Claude Code engine). The single highest-impact, smallest-meaningful fix is a network-allowlist correction in Daily Semgrep Scan: 7 requests to pypi.org:443 were blocked during this run, and a further 10 unknown-SNI requests were dropped, giving the workflow a 57% block ratio (17/30) — the highest of any workflow in the window. Adding pypi.org and files.pythonhosted.org to its network.allowed list eliminates the named-domain blocks and is a one-line frontmatter change.

AgentRx Evidence

• Critical step: network step of trajectory Daily Semgrep Scan (run §26015872094) — category network.egress_blocked, severity high.
• Failure category (from judge): network.allowlist_misconfiguration (rule-based; LLM judge skipped — see Artifacts).
• Frequency / impact: 7 named pypi.org:443 blocks + 10 unknown-SNI blocks in a single 4.6-minute run; 57% block ratio. Across the day, the fleet-wide block rate is 299/846 = 35% — pypi.org is the only commonly-named missing domain among scheduled workflows.
• Representative runs: §26015872094 (Daily Semgrep Scan, primary), §26014589786 (Documentation Noob Tester — high block rate but named-domains are Chrome/Google telemetry, separate fix), §26016026133 (Workflow Health Manager — 48 unknown-SNI blocks, generic copilot-engine pattern).

Labeled Violations

Note: rows 3–10 share an unknown-SNI block pattern (no named blocked domain). Those are likely Copilot-CLI auxiliary requests that lack SNI; they are silent and not the smallest fix. Row 1 is the only entry where the blocked domain is named, well-known, and trivially allowlistable, which is why it is selected as the critical step.

Recommended Optimization

Add an explicit network: block to .github/workflows/daily-semgrep-scan.md that augments the default allowlist with pypi.org and files.pythonhosted.org:

network:
  allowed:
    - defaults
    - pypi.org
    - files.pythonhosted.org

• Why this is highest impact: it is the only top-blocked workflow with a named blocked domain that maps to a well-understood dependency surface (Python wheels / source dists). The repo already allowlists these for audit-workflows and daily-choice-test, so precedent exists. Every other top-blocked workflow shows only unknown-SNI blocks, which require deeper investigation (likely Copilot-CLI auxiliary endpoints) before they can be safely fixed.
• Where to implement: .github/workflows/daily-semgrep-scan.md (frontmatter), then re-compile to refresh .github/workflows/daily-semgrep-scan.lock.yml.

Validation Plan

On the next scheduled run of Daily Semgrep Scan:

• Primary: firewall.by_workflow['Daily Semgrep Scan'].blocked_domains no longer contains pypi.org:443; requests_by_domain['pypi.org:443'].blocked drops from 7 → 0.
• Secondary: block ratio for the workflow drops from 57% (17/30) to ≤35% (the remaining unknown-SNI blocks are out of scope).
• Guardrail: run_success_rate and alert_creation_rate of the existing semgrep_output_format experiment do not regress.
• Counterfactual: a workflow_dispatch invocation immediately after merge should show the same block-rate improvement as the next scheduled run.
