DeepReport Intelligence Briefing - 2026-09-28 (18:00Z cycle)

🔍 Executive Summary

Fleet health is stable overall (0% firewall blocks, 100% redaction/permissions coverage across 298 workflows), but a shared secret-redaction crash is quietly inflating the driver_exit failure count fleet-wide, and two chronic documentation-drift patterns (skill-file stale paths, Claude OAuth-token gap) each got a concrete, cheap fix filed today after sitting unactioned for 3 audit cycles and 37 daily runs respectively. Most urgent: fix the findFiles() stack-overflow crash in redact_secrets.cjs — it's masking already-successful agent runs as failures across ~30 different workflows.

🚨 Top 5 Findings

• Shared infra bug inflates failure rate: redact_secrets.cjs's recursive directory scan crashes with Maximum call stack size exceeded on /tmp/gh-aw/aw-mcp, hitting two different engines (Codex, Claude) in unrelated workflows — both times after the agent had already succeeded. A 100-run fleet sample put driver_exit (infra) failures at 65% of all failures, spread thin across ~30 workflows — consistent with exactly this kind of single shared-infra bug. Filed as an issue.
• Skill-doc drift, 3rd recurrence, getting worse not better: 4 skill files (messages, javascript-refactoring, error-pattern-safety, temporary-id-safe-output) still point at the emptied pkg/workflow/js/ directory instead of the real actions/setup/js/ (862 files) — 22 stale refs now, up from 20 twelve days ago, despite two prior audits reporting it. Filed with exact line numbers plus a proposed regression guard.
• Claude OAuth-token gap undocumented at the one place users land first: CLAUDE_CODE_OAUTH_TOKEN is documented as unsupported/silently-ignored on 4 other pages, but not in quick-start.mdx's Claude section — flagged unresolved for 37 consecutive daily runs without ever being converted into a tracked fix. Filed as a one-line doc addition.
• UK AI Resilience governance loop is functioning well: 93% of 277 open code-scanning alerts already have tracking issues; 2 newly-surfaced CodeQL alerts in files touched today were triaged (one matches an established false-positive pattern, the other — allocation-size-overflow in create_code_scanning_alert.go — is a minor pre-allocation guard, left to the existing UK AI Resilience workflow's own remediation queue since it self-tracks with a 14-day SLA).
• Agent Performance Report still blocked, 17th consecutive run: metrics pipeline (Metrics Collector → ranking) has been stale since 2026-09-01; this is a standing, previously-flagged chronic blocker with no new information this cycle, not re-filed.

✅ Actionable Agentic Tasks

1. Fix stale pkg/workflow/js/ references in 4 skill files (Quick, <1h) — mechanical find/replace across 22 occurrences + add a path-existence regression test. Issue filed.
2. Fix secret-redaction stack-overflow crash on deep aw-mcp trees (Medium, 1-4h) — convert findFiles() in redact_secrets.cjs to iterative traversal; likely the single largest source of fleet-wide driver_exit failures. Issue filed.
3. Add quick-start.mdx callout for the silently-ignored CLAUDE_CODE_OAUTH_TOKEN (Fast, <30min) — one line, closes a 37-run-old gap at the page new users actually read first. Issue filed.
4. (No 4th–7th task filed this cycle) — remaining candidates from this ~11h window (MCP tool response overhead/icon bloat, PR Sous Chef high-token failures, UK AI Resilience CodeQL triage, redaction/permissions CI-gate formalization) either belonged to external MCP server behavior, were already self-tracked by their originating workflow with an SLA, or were too vague to convert into an independently verifiable fix this cycle. Narrow-window cycles historically yield 0-3 filed issues; 3 verified, non-duplicate, high-confidence fixes were prioritized over padding to 7.

Cycle metadata

• Window: ~10.8h since prior briefing DeepReport Intelligence Briefing - 2026-09-28 #63952 (created 2026-09-28T07:10:41Z). 16 new discussions in window.
• Repo-memory note: last_analysis_timestamp.md/known_patterns.md/flagged_items.md in repo-memory had not been updated since 2026-09-08 despite 20+ days of subsequent briefings existing as discussions (DeepReport Intelligence Briefing - 2026-09-08 #59329 → DeepReport Intelligence Briefing - 2026-09-28 #63952) — memory write-back appears to have silently stalled for ~3 weeks. This cycle picked up from the discussion record directly (DeepReport Intelligence Briefing - 2026-09-28 #63952) rather than trusting the stale repo-memory files, and refreshed all memory files to close the gap.
• 3 issues filed, all independently re-verified against current main before filing (not taken on the source report's word alone).
• Weekly issues data (500, from prior fetch) not re-analyzed in depth this cycle — Issue Arborist ([Issue Arborist] Issue Arborist Daily Report #63933) and Auto-Triage ([Auto-Triage] Auto-Triage Issues Report #63946) already covered backlog grouping/labeling today with no gaps for DeepReport to add to.
