🔐 Daily Secrets Analysis Report

Date: 2026-08-05
Workflow Files Analyzed: 275
Run: §31033152097

📊 Executive Summary

• Total Secret References: 9,249 (secrets.*)
• GitHub Token References: 2,077 (github.token)
• Unique Secret Types: 41 (excluding a blank capture artifact)
• Job-Level Usage: 0 (0%) — secrets are not injected at job-level env: blocks
• Step-Level Usage: 4,139 (100%) — all secret refs appear scoped to individual step env: blocks

🛡️ Security Posture

✅ Redaction System: 275/275 workflows have redaction steps (100% coverage)
✅ Token Cascades: 985 instances of fallback chains (GH_AW_GITHUB_MCP_SERVER_TOKEN || secrets.GH_AW_GITHUB_TOKEN || secrets.GITHUB_TOKEN)
✅ Permission Blocks: 275 explicit permission definitions (1 per workflow — fully covered)

Template injection check: 5,112 occurrences of github.event. patterns found across lock files. These are expected — expressions are consistently routed through env: interpolation rather than direct shell/script interpolation, which is the safe pattern gh-aw enforces at compile time. No raw unsafe interpolation detected in spot checks.

Secrets-in-outputs check: Initial grep flagged 34 matches, but manual verification confirmed these are false positives from context-window overlap in the search (unrelated outputs: blocks followed much later by unrelated secrets.* lines in Docker command construction). ✅ No actual secret exposure in job outputs: found.

🎯 Key Findings

1. GITHUB_TOKEN and GH_AW_GITHUB_TOKEN dominate usage — combined ~9,000+ references (97% of all secret refs), consistent with the token-cascade pattern used for GitHub API auth across MCP servers and safe-outputs.
2. Step-level-only secret injection — no job-level env: blocks reference secrets directly; every workflow scopes secrets to the specific step that needs them, minimizing blast radius/exposure surface.
3. LLM provider keys are well-isolated — ANTHROPIC_API_KEY (264), OPENAI_API_KEY (107), and CODEX_API_KEY (106) appear only in engine-specific steps, with no overlap into unrelated jobs based on sampling.
4. Full redaction and permission coverage — 100% of the 275 lock files include both a redaction step and an explicit permissions: block, indicating consistent application of the compiler's safety defaults.

💡 Recommendations

1. No action required — secret usage patterns remain consistent with expected step-scoped, redacted, cascade-based design; no anomalies or regressions detected.
2. Continue monitoring GH_AW_SIDE_REPO_PAT (24) and GH_AW_AGENT_TOKEN (15) usage — these are lower-frequency, higher-privilege tokens; periodic review of which workflows use them is worthwhile to ensure least-privilege stays intact as new workflows are added.

📈 Trends

No historical baseline is available yet for this repository run — this establishes the first tracked snapshot (2026-08-05: 275 workflows, 9,249 secret refs, 41 unique secret types, 100% redaction coverage). Future runs will compare against this baseline.
