🤖 Copilot Agent Session Analysis — 2026-09-11

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-09-11, 05:15–06:16 UTC (most recent 50 workflow runs)
• Completion Rate: 30.0%
• Average Duration: 5.9 min (median 0.0 min)
• Experimental Strategy: none (roll=87, standard run)

⚠️ Data availability note: Conversation transcript logs ({run_id}-conversation.txt) have been empty for 21 consecutive recorded days (0 files found in logs/ again today). This analysis is therefore metadata-only — built from workflow run status/timing, not turn-by-turn agent behavior. No loop detection, tool-usage, or prompt-quality metrics are possible from real transcripts this run. See the system-improvement recommendations below.

Key Metrics

Metric	Value	Trend (vs 09-10)
Total Sessions	50	→
Successful Completions	15 (30.0%)	↑ (+4 sessions, +8pts)
Failed / action_required	35 (70.0%)	↓ (−4 sessions)
Average Duration	5.9 min	↑ (+1.5 min)
Loop Detection Rate	N/A — no transcripts	—
Context Issues	N/A — no transcripts	—

Success Factors ✅

1. True agentic completions stay perfect: The 4 genuine task-completion workflows today (Addressing comment on PR #60183, #60135, #60136, Running Copilot cloud agent) all succeeded — 4/4 = 100%. This is the 6th consecutive day at 100% (09-06 11/11, 09-07 5/5, 09-08 7/7, 09-09 5/5, 09-10 3/3, 09-11 4/4). Real task failures remain rare; nearly all "failure" signal in the dataset comes from CI-gate/review-bot noise, not the agent itself.

   • Example: the longest session today, Addressing comment on PR #60136 (42.3 min), completed successfully.

2. Branch diversity dilutes single-branch blast radius: Today's 50 sessions split across 4 branches almost evenly — copilot/update-logs-command-audit-result 22/50 (44%), copilot/fix-github-actions-job 12/50 (24%), copilot/fix-aic-persist-scan-observations 12/50 (24%), copilot/fix-confused-deputy-check 4/50 (8%) — the most even split recorded, versus 09-10's 2-branch/96%-concentration day.

3. The largest branch converts well once merge noise is excluded: copilot/update-logs-command-audit-result (22 sessions) has 12 success / 5 failure / 5 action_required. Excluding the 2 merge-cascade-invalidated failures (see below), the real conversion rate is 12/20 = 60%.

Failure Signals ⚠️

1. merge_invalidation_cascade (5th occurrence): PR Cache audit results in logs JSONL #60183 merged at 05:51:43Z; the CGO and CWI gate runs on its branch both reported conclusion=failure one second later at 05:51:44Z — verified via gh pr view 60183. These are gates invalidated mid-flight by the merge, not real task failures. This pattern has now recurred on 5 of the last 6 recorded days (09-06, 09-07, 09-09, 09-10, 09-11) and should be filtered out of raw failure-rate metrics.

2. branch_level_stuck_gate on two branches at once (new): For the first time, two branches simultaneously showed near-total action_required gate bundles — copilot/fix-aic-persist-scan-observations (11/12 = 91.7%) and copilot/fix-github-actions-job (11/12 = 91.7%). Both have actively-assigned PRs (pelikhan + Copilot, PR Fix daily AIC snapshot completeness and quota handling #60136 and Prevent Jira smoke workflow failures when credentials are unavailable #60199) updated within the last hour, matching the 09-10 refinement: branch-wide action_required reflects gates queued behind active review, not an abandoned branch. Still, it represents meaningful CI capacity sitting idle pending review/rerun.

3. Independent review-gate failures: PR Code Quality Reviewer, Matt Pocock Skills Reviewer, and Impeccable Skills Reviewer each failed on copilot/update-logs-command-audit-result at distinct timestamps (05:34:22Z, 05:48:32Z, 05:48:59Z) — unrelated to the merge cascade (which happened later, at 05:51:44Z). Three independent review-bot failures on one branch in under 15 minutes is worth a manual look.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Not measurable this run: the 50 analyzed items are CI/CD workflow runs (gate checks, review bots, and a handful of genuine Copilot agent task runs), not individually-authored task prompts with available transcripts. No conversation logs exist to extract prompt text, so quality scoring (high/medium/low) cannot be computed. This has been true for 21 consecutive recorded days — see the tooling recommendation below to unblock this.

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 12 open PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (mean over 20 recorded prior days)
• Status: NORMAL — 21st consecutive day at 0.0%, no branch has crossed the ≥5-gate/no-agent/>1h threshold

Escalation Candidate Details

Only 5 workflow runs were in-progress in the last 6 hours: 3 on main, 2 on revert-release-app-token (max 2 gates on any single branch — well under the ≥5 threshold).

✅ No orphaned branches exceed the escalation threshold today.

CI Waste Estimate

No orphaned-branch CI waste identified today (0 escalation candidates). Separately, the two branch_level_stuck_gate branches above represent ~22 action_required sessions queued behind active review — not orphaned, but worth monitoring if either branch stalls past today.

Experimental Analysis

This run included experimental strategy: none

Standard analysis only — random roll was 87 (≥30 threshold), so no experimental strategy was triggered this run. The standing metric from a prior experimental promotion (burst_clustering_temporal_density) was still tracked:

• burst_clustering_temporal_density (standing since 09-08): direction held a 5th consecutive day — isolated-fire sessions succeed more than burst-fired ones (33.3% vs 28.9%), but the gap is now the weakest ever recorded (1.15x, down from 8x → 3.8x → 1.27x → 1.6x → 1.15x). This tracks with today having the most branch diversity in a week — the metric appears to lose discriminative power as branch concentration drops.

Actionable Recommendations

For Users Writing Task Descriptions

1. Keep PRs actively assigned and reviewed promptly: Both branch_level_stuck_gate branches today had active assignees and recent updates, which is exactly what distinguishes "gates queued behind review" from "orphaned branch." Assign a reviewer as soon as a Copilot PR opens to avoid the pileup effect.
2. Prefer fewer, more consolidated branches for related work: today's most-even branch split (4 branches, no single one over 44%) coincided with a healthier overall completion rate than recent single-branch-concentration days.

For System Improvements

1. Filter merge-invalidated cascade failures out of raw failure metrics: 2 of today's 5 "failures" (and the same pattern on 5 of the last 6 days) are same-second artifacts of a PR merging while gates are in flight, not real defects. Potential impact: High — this metric has directly inflated failure rate and average duration on 5 of the last 6 recorded days.
2. Investigate independent review-bot failures on copilot/update-logs-command-audit-result: three separate reviewer workflows failed within 15 minutes, unrelated to the later merge cascade. Potential impact: Medium.

For Tool Development

1. Unblock conversation-transcript capture for actual Copilot agent runs: 0 transcript files for the 21st consecutive recorded day. Frequency of need: every run (50/50 sessions, every day analyzed since tracking began). Use case: this is the single biggest gap blocking the behavioral analysis (loop detection, tool-usage patterns, prompt-quality scoring) this workflow was designed to produce — right now it can only report CI-gate metadata.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: Saw-tooth pattern continues; today's 30.0% sits almost exactly on the 21-day mean (29.7%, range 4–78%), a +8pt rebound from 09-10's 22.0%.
• Average duration trend: 5.9 min today, down sharply from the 09-01/09-07/09-09 spikes (26.3, 24.0, 19.6 min) that were themselves driven by merge-cascade sessions sitting pending for 60+ minutes before invalidation.
• Quality improvement: Not assessable without transcripts; the true-agentic 100%-success streak (6 days running) is the closest available proxy for genuine task quality.

📈 Session Trends Analysis

Completion Patterns

Completion rate (30.0%) landed almost exactly on the 21-day trend line (29.7% mean) after 09-10's dip to 22.0%. The saw-tooth pattern between successful and failed/action_required counts continues, with no sustained upward or downward trend across the 21 days observed.

Duration & Efficiency

Average duration (5.9 min) stayed well below the recurring spikes seen on 09-01, 09-07, and 09-09 (19.6–26.3 min), all of which were traced to merge-invalidation-cascade sessions sitting pending before being invalidated. Median duration remains 0.0 min most days, reflecting that the majority of sessions are instantaneous CI-gate stubs rather than long-running agent work.
