🤖 Copilot Agent Session Analysis — 2026-10-28

Executive Summary

• Sessions Analyzed: 50 (GitHub Actions workflow runs — see data-quality note below)
• Analysis Period: 2026-10-27 14:59:56Z – 16:03:21Z (single ~63-minute snapshot window)
• Completion Rate: 8.0% (4/50)
• Average Duration: 7.27 min (median 0.0 min)
• Experimental Strategy: None — standard run (roll=77, threshold <30 for experimental)

⚠️ Data quality notice: 0/50 conversation/event-log transcripts were available today (/tmp/gh-aw/agent/session-data/logs/ was empty), so no turn-by-turn tool-usage, token-efficiency, or loop-detection analysis was possible. This continues a long-running regression (conversation .txt transcripts have been empty for 40+ consecutive recorded days; partial events.jsonl recoveries occurred on 10-14/10-16/10-17/10-21/10-26/10-27 but not today). All metrics below are derived from workflow-run metadata (status/conclusion/timestamps/branch/name) in sessions-list.json, not from genuine agent conversation behavior.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	4 (8.0%)	↓↓ (-32pts vs 10-27's 40.0%)
Action Required / Pending	46 (92.0%)	↑↑
Average Duration	7.27 min	↓ (vs 9.72 min on 10-27)
Loop Detection Rate	N/A (no transcripts)	→
Context Issues	N/A (no transcripts)	→

Success Factors ✅

Patterns associated with the 4 successful runs today (metadata-only, small sample):

1. True-agentic PR-comment response completes reliably: "Addressing comment on PR Allow on.bots Apps to check out same-repository PRs on edited events #72403" succeeded in 21.3 min.
   • Success rate: 1/1 today; consistent with the 56-day true_agentic_100pct_streak pattern (historically ~87-100% success for this workflow family).
2. Core CI-gate workflows complete once unblocked: CJS (168.9 min) and Doc Build - Deploy (166.2 min) both succeeded on the same branch as the merged PR Allow on.bots Apps to check out same-repository PRs on edited events #72403 work.
   • Success rate: 2/2 on that branch today.
3. Code-scanning finishes autonomously: "Code scanning AI findings on PR Allow on.bots Apps to check out same-repository PRs on edited events #72403" succeeded in 6.8 min with no human gating required.

[Sample too small (n=4) for robust generalization — see 56-day historical pattern library in cache memory for higher-confidence versions of these factors.]

Failure Signals ⚠️

1. Mass smoke-test-suite bundle fire (NEW pattern): 40 of 50 runs (80% of today's volume) — the entire per-engine smoke-test matrix (36 distinct Smoke * workflows covering Claude, Codex, Cursor, Gemini, Aider, Goose, Kiro, OpenCode, Pi, DeepSeek Harness, etc., plus Agent Container Smoke Test, Code Refiner, Changeset Generator, and Design Decision Gate) — fired together in a single 1-second window (15:36:53–54Z) on branch copilot/support-claude-on-vertex-ai, all landing action_required, all zero-duration.
   • "Failure" rate: 100% of this bundle (40/40) went action_required, not genuine failure — consistent with gates queued pending required approval/review rather than abandonment.
   • This is the dominant driver of today's low completion rate; a PR touching shared workflow-trigger configuration (e.g. cross-cutting engine-support changes) appears to cause GitHub Actions to queue the full smoke-test suite at once, rather than the usual ~4–10-workflow core-CI-gate bundle.
2. Provenance-ambiguous channel still blocked: "Squad" (2) and "Agentic Commands" (5) — 7 firings, all action_required, 0% success today, consistent with their historical near-always-blocked status.
3. No genuine behavioral failure signal observable: with 0/50 transcripts, we cannot distinguish "agent got stuck" from "workflow correctly waiting on required review" — this is itself the top risk flagged below.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

No prompt text or conversation turns were available in today's data (0/50 transcripts fetched). Prompt-quality scoring, high/low-quality examples, and clarification-request tracking could not be performed this run. This has been the case for the large majority of the last 56 recorded days; only 6 days (10-14, 10-16, 10-17, 10-21, 10-26, 10-27) had any partial transcript coverage, and even those covered only 1-3 PR-review-bot sessions out of 50, never true coding/implementation sessions.

Orphaned Branch Escalation Alerts 🚨

Branches with ≥5 simultaneous gate firings and no Copilot agent assigned for >2 hours.

Summary

• Orphaned Branches Today: 0 out of 13 open PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (30-day mean over 30 recorded days)
• Status: NORMAL (0.0% vs 0.0% baseline; 56th consecutive healthy day)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. Of 13 open PRs, only 2 workflow runs were in-progress at check time (both on main, not on any PR branch), so no branch reached the ≥5-gate threshold.

CI Waste Estimate

• Orphaned gate-hours today: 0 (no escalation candidates)
• Recoverable capacity: N/A — no orphaned branches to recover capacity from. (Separately, the 40-run smoke-test bundle fire noted above represents its own category of simultaneous CI queuing, but none of those runs are on a branch with an unassigned, orphaned open PR — copilot/support-claude-on-vertex-ai has both pelikhan and Copilot already assigned on PR Support Claude on Vertex AI with GCP WIF #72273.)

Actionable Recommendations

For Users Writing Task Descriptions

1. No prompt-level recommendations possible today: with 0/50 conversation transcripts, there is no prompt text to assess. This recommendation itself repeats from nearly every recent snapshot — see "For System Improvements" below.

For System Improvements

1. Fix the conversation/event-log data pipeline: this is now a 40+ day regression. The copilot-session-data-fetch shared module is consistently selecting CI-gate/review-bot/smoke-test workflow runs rather than genuine Copilot coding-agent sessions, and even on partial-recovery days only captures 1-3 PR-review-bot sessions. Without this fix, no turn-by-turn behavioral analysis (tool usage, token efficiency, loop detection, prompt quality) is possible, and this report remains CI-metadata-only.
   • Potential impact: High — this is the single largest blocker to the stated mission of this workflow.
2. Investigate the smoke-test-suite bundle-fire trigger: confirm whether the PR on copilot/support-claude-on-vertex-ai intentionally touches shared workflow-trigger configuration (causing all 36+ smoke-test workflows to queue simultaneously), or whether this is an unintended side effect worth tightening path filters for.
   • Potential impact: Medium — reduces CI queue noise/cost, though today's instance caused no orphan-escalation harm (PR already has Copilot + a human assigned).

For Tool Development

1. No conversation-transcript access: 0 sessions out of 50 had tool-call or token data available, same gap flagged on nearly every prior day in this series.
   • Frequency of need: 50/50 sessions today (56th+ consecutive day of near-total absence)
   • Use case: Enables loop detection, prompt-quality scoring, and tool-usage pattern analysis — the core stated mission of this workflow.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: 8.0% today vs 55-day prior mean of 37.0% (range 4.0-80.0%) — 3rd-lowest of 56 recorded days, behind the 4.0% ties on 2026-08-31 and 2026-10-24. A sharp -32pt drop from 10-27's 40.0%, driven almost entirely by the smoke-test bundle-fire population shift rather than a genuine agent-quality regression.
• Average duration trend: 7.27 min today, down from 9.72 min (10-27) and well below 10-26's 35.6 min outlier spike; 46/50 runs were zero-duration (instant queue/block), consistent with the bundle-fire population.
• Quality improvement: Not assessable — no behavioral/prompt data available today or across the majority of the 56-day record.

Orphan rate:                 0.0% (0/13 open PRs), 56th consecutive healthy day

Next Steps

• Prioritize fixing the copilot-session-data-fetch conversation/event-log pipeline (40+ day regression blocking the core mission of this workflow)
• Confirm whether the copilot/support-claude-on-vertex-ai smoke-test-suite bundle fire was an intended full-matrix trigger
• Re-run behavioral analysis once transcript coverage improves beyond the recent 1-3/50 partial-recovery level
• Continue monitoring orphaned-branch escalation (currently 56 consecutive healthy days at 0%)

📈 Session Trends Analysis

Completion Patterns

Completion rate has been highly volatile over the last 30 recorded days (range 4.0%-80.0%), oscillating in a saw-tooth pattern rather than trending steadily in either direction. Today's 8.0% is a sharp reversal from 10-26's 74.0% recent high, landing among the 3 lowest readings in the entire 56-day record. The volatility correlates closely with which branch/population of workflow runs happens to be sampled each day (CI-gate-heavy vs smoke-test-heavy vs true-agentic-heavy), rather than reflecting a steady system-wide quality trend.

Duration & Efficiency

Mean and median session duration have both stayed low and volatile across the last 30 days, with occasional outlier spikes (10-26's ~35.6 min mean) driven by a handful of long-running CI jobs rather than a population-wide shift. No loop-count data could be plotted on any day in this window since conversation/event-log transcripts have been almost entirely unavailable; the bar overlay remains at zero throughout, which is itself the chart's most important finding — not an absence of loops, but an absence of visibility into them.
