6h Cycle Update — 2026-04-19 07:09 UTC (§24623487281)

Executive Summary

47 runs in the last 6h (36 copilot, 11 claude). 5 failures detected; 2 are new untracked bugs.

Failure Cluster Table

Run	Workflow	Engine	Failure Mode	Status
§24623096622	Issue Monster	copilot	assign_to_agent uses issue-number instead of issue_number (3 errors)	New → sub-issue created
§24622541959	Artifacts Summary	copilot	Engine terminated unexpectedly (Copilot stuck in Read loop)	Tracked in #27155
§24622002167	Contribution Check	copilot	add_labels missing item_number (no issue/PR number)	New → sub-issue created
§24620886472	GitHub Remote MCP Auth Test	copilot	Transient Copilot API server errors (5 retries)	Transient — not tracked
§24618004586	Contribution Check	copilot	Too many noop items. Maximum allowed: 1.	Covered in Contribution Check sub-issue

Existing Issue Correlation

• Codex 401 ([aw-failures] Codex engine 401 auth failure — OPENAI_API_KEY credential missing or invalid #27127): Codex engine workflows (ai-moderator, daily-observability-report) did not run in this 6h window — issue remains open and unresolved.
• Artifacts Summary ([aw] Artifacts Summary failed #27155): Already tracked, expires today.
• Lock files out of sync ([aw] agentic workflows out of sync #27140): Ongoing, unrelated to agent failures.

Sub-Issues Created This Cycle

Two new sub-issues created and linked to this parent:

1. Issue Monster: assign_to_agent field naming bug (issue-number vs issue_number)
2. Contribution Check: recurring safe-output validation failures (noop limit + add_labels missing number)

Note: The agenticworkflows CLI bridge count integer parameter bug (#27149) was independently discovered by daily-cli-tools-tester — this is a known issue.

6h Cycle Update — 2026-04-19 13:09 UTC (§24629827117)

Executive Summary

33 runs in the last 6h (26 success, 5 failure, 2 in-progress). 5 failures detected across 3 engines. 4 already have existing tracking; 1 new pattern identified (false-failure in Multi-Device Docs Tester).

Failure Cluster Table

Run	Workflow	Engine	Duration	Failure Mode	Tracked
§24626840251	Daily Issues Report Generator	copilot	5m	node: command not found	#27165
§24627195348	Daily Community Attribution Updater	copilot	32.9m	Permission denied running Python script	#27173
§24628420682	Duplicate Code Detector	codex	2.3m	401 Unauthorized — OPENAI_API_KEY missing/expired	#27177 / #27127
§24628589681	Multi-Device Docs Tester	claude	6.9m	Agent succeeded (all 10 devices OK), safe_outputs failed — upload_artifact error + 60% firewall block rate	New → #aw_mdtfail
§24629165601	GitHub MCP Remote Server Tools Report Generator	claude	9.2m	Protected files + discussion creation failed	#27185

Existing Issue Correlation

• Codex 401 ([aw-failures] Codex engine 401 auth failure — OPENAI_API_KEY credential missing or invalid #27127): Still unresolved P0 — another Duplicate Code Detector failure confirms OPENAI_API_KEY is still missing
• Copilot node: command not found ([aw] Daily Issues Report Generator failed #27165): Recurring Copilot runner environment issue — node binary absent from execution context
• Copilot permission denied ([aw] Daily Community Attribution Updater failed #27173): Recurring Copilot environment issue — Python script cannot execute
• GitHub MCP Remote Tools ([aw] GitHub MCP Remote Server Tools Report Generator failed #27185): Protected files issue — configure protected-files: fallback-to-issue or add .github/aw/github-mcp-server.md to allowed-files

Sub-Issues Created This Cycle

1. #aw_mdtfail — Multi-Device Docs Tester: upload_artifact fails in safe_outputs job despite agent reporting all 10 device tests passed. 60% firewall block rate from Chrome/Playwright Google domain calls (SafeBrowsing, telemetry).

Key Observations

• 15% failure rate (5/33) consistent with previous cycles
• Codex 401 ([aw-failures] Codex engine 401 auth failure — OPENAI_API_KEY credential missing or invalid #27127) remains unresolved P0 — every Codex workflow continues to fail
• Multi-Device Docs Tester is a false-failure: agent completes successfully but workflow reports failure due to upload_artifact mismatch
• Copilot Copilot environment crashes (node: command not found, permission denied) affect 2 workflows — possible regression in Copilot CLI v1.0.21 or runner setup

Quality Signals (no failures, but worth monitoring)

View Efficiency Flags

Q workflow (§24635766604) — resource_heavy_for_domain (HIGH), poor_agentic_control (MEDIUM):

• 61 turns, 4.2M tokens, 12.7m for an issue_response task
• 1 firewall-blocked request to invalid.example.invalid:443 (likely URL from issue content — blocked correctly)
• ~95% of turns were data-gathering; agentic_fraction=0.05

Design Decision Gate (§24636318512) — resource_heavy_for_domain (HIGH):

• github.pull_request_read called 11 times across 11 turns (same PR re-fetched every turn)
• Integrity filter blocked pull_request_read 3 times; agent retried each block rather than branching

Contribution Check (§24634412711) — resource_heavy_for_domain (HIGH):

• 19 inference-only turns, 0 external tool calls — agent re-reasoned over static context repeatedly

Existing Issue Correlation

• Codex 401 ([aw-failures] Codex engine 401 auth failure — OPENAI_API_KEY credential missing or invalid #27127): No Codex runs in this 6h window — issue remains open and unresolved P0.
• Other tracked failures ([aw] Daily Issues Report Generator failed #27165, [aw] Daily Community Attribution Updater failed #27173, [aw] Duplicate Code Detector failed #27177, [aw] GitHub MCP Remote Server Tools Report Generator failed #27185): No recurrence in this window.

Sub-Issues Created This Cycle

None. All runs succeeded; efficiency flags are recurring patterns not yet meeting threshold for new sub-issues.

6h Cycle Update — 2026-04-20 01:12 UTC (§24643864137)

Executive Summary

29 runs in the last 6h (19 copilot, 9 claude, 1 codex). 2 real failures detected at 23:44 UTC; root cause is GitHub App installation rate limit exhaustion from concurrent scheduling. 1 Smoke CI cancel was benign (push-superseded).

Failure Cluster Table

Run	Workflow	Engine	Failure Mode	Status
§24642041999	Daily Observability Report for AWF Firewall and MCP Gateway	codex	API rate limit exceeded for installation at guard policy init	New → sub-issue created
§24642045134	Daily Safe Output Tool Optimizer	claude	exit code 1, 0 tokens — likely same rate limit event (same SHA, same time)	Covered in same sub-issue
§24642364577	Smoke CI	copilot	Cancelled — push superseded by newer push; next run succeeded	Transient — not tracked

Root Cause Detail

Both failures fired at 23:44 UTC on 2026-04-19 on the same SHA (5285e620). The Daily Observability Report emitted an explicit rate limit error: Failed to determine automatic guard policy: API rate limit exceeded for installation (Request ID: BC40:E2DAD:30788C:C36940:69E5694A). The Daily Safe Output Tool Optimizer failed with just exit code 1 and 0 agent turns — audit confirmed no behavioral regression vs. prior success, pointing to the same pre-agent infrastructure failure.

Existing Issue Correlation

• Codex 401 ([aw-failures] Codex engine 401 auth failure — OPENAI_API_KEY credential missing or invalid #27127): Still open P0. No new Codex 401 runs in this window; rate limit issue is a separate root cause from the 401 auth failure tracked there.
• All other open issues: No recurrence in this window.

Sub-Issues Created This Cycle

1. #aw_ratelim1 — GitHub App installation rate limit exhaustion from co-scheduled workflows — proposes staggering cron schedules and adding retry with backoff at guard policy layer.
