🤖 Copilot Agent Session Analysis — 2026-05-30

Executive Summary

The most recent 50 sessions show a rebound to 26% completion (13/50), recovering from the 14% dip on 05-29. Activity stayed extremely concentrated — 2 branches account for 100% of sessions. Headline finding: a standing assumption broke. Synchronized gate-sweep bursts are not uniformly action_required — the 25-session burst on copilot/fix-pi-agent-configuration produced 7 successes + 16 skips, while a parallel 7-session burst on copilot/share-runner-temp-env-var was 100% action_required. Burst outcome tracks branch approval state, not the burst itself.

⚠️ Data quality: Agent conversation transcripts were empty for the 7th consecutive day (logs/ empty). This is metadata-only analysis — loop detection, context-confusion, and prompt-quality scoring cannot be computed from CI run metadata and are reported N/A.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	13 (26%)	↑ from 14%
Failed	9 (18%)	↑
Action Required	11 (22%)	↓ from 84%
Skipped (gate sweeps)	17 (34%)	↑
Average Duration	2.23 min	↓ from 3.01
Median Duration	0.18 min	→
Unique Branches	2	→
Orphan Escalations	0	→

Success Factors ✅

1. Approved branches convert gate-sweeps into successes: fix-pi-agent-configuration reached 32.4% success (12/37). Once approved, gate sweeps resolve to success/skipped instead of stalling. Its 25-session burst yielded 7 success + 16 skipped + 2 failure.
2. Productive work has a duration floor: 10 of 13 successes ran 2.9–18.95 min; the 3 sub-30s "successes" (0.13/0.15/0.47 min) are null-op smokes. Sessions under ~1 min are rarely real work.
3. Long-session presence resumed: 8 sessions ≥5 min, 3 ≥15 min (max 18.95 min), all on the lead branch.

Failure Signals ⚠️

1. Branch-specific gating drag: share-runner-temp-env-var managed only 7.7% success (1/13); its 7-session burst was 100% action_required — a PR awaiting first-party approval, so every retry stalls.
2. Gated retry waves inflate counts without value: bursts cover 35/50 sessions; on gated branches they are pure action_required noise.
3. Concentration risk: 100% top-2 branch share for the 2nd straight day — the completion rate is hostage to 1–2 PRs' approval status, not agent capability.

Prompt Quality Analysis 📝

Prompt-level analysis is not available — session data is CI gate-sweep run metadata, not agent task prompts, and transcripts are empty (day 7). Inference from metadata: success is gated on branch approval state rather than prompt characteristics — the same workflow set succeeds on an approved branch and is 100% action_required on a pending one. This is a process/permission bottleneck, not a prompt problem.

Orphaned Branch Escalation Alerts 🚨

• Orphaned Branches Today: 0 of 2 session-active branches (0%)
• Historical Baseline: ~40% orphaned rate — Status: ✅ NORMAL

Escalation & Assignment Detail

✅ No orphaned branches exceed the escalation threshold today. At analysis time all 3 in-progress runs were on main (the analysis workflows) — no PR branch had active gate firings, so none can meet the ≥5-gate threshold.

Branch	PR	Agent	Active Gates	Status
share-runner-temp-env-var	#35880	✅ Copilot	0	Session branch
fix-pi-agent-configuration	#35836	✅ Copilot	0	Session branch
chaos/* (5 PRs)	#35869-73	❌ none	0	Idle
salmanmkc/setup-copilot-resolver	#34918	❌ none	0	Idle

• Unassigned open PRs: 6/8 (75%) — but all idle (0 gate firings), so unassigned ≠ orphaned. None qualify.
• CI waste from orphans: 0 gate-hours.

📈 Session Trends

Completion Patterns

Completion rebounded to 26% after the 05-29 regression, continuing the oscillation (44→2→0→46→22→28→14→26). Today sits mid-range — above the 0–2% troughs, below the 44–46% peaks.

Duration & Efficiency

Average duration eased to 2.23 min while productive volume held at 13. The strongly bimodal shape persists (median 0.18 vs mean 2.23 min, ~12×): 37 sub-30s gate sweeps drag the median, a tail of 8 sessions ≥5 min carries the real work.

Notable Observations

Burst, Duration & Diagnostic Detail

Burst analysis (key finding) — 3 events (≥3 sessions sharing branch+timestamp), 35/50 sessions:

• fix-pi @05:59:22 — 25 sessions: 7 success / 16 skipped / 2 failure
• fix-pi @05:56:16 — 3 sessions: 2 success / 1 failure
• share-runner @06:25:13 — 7 sessions: 100% action_required

Yesterday's synchronized_burst_saturation ("bursts = 100% action_required") is superseded by new pattern burst_outcome_branch_dependence.

Duration: 37 <30s, 8 ≥5 min, 4 ≥10 min, 3 ≥15 min. Success durations (min): 0.13, 0.15, 0.47, 2.92, 3.20, 3.52, 4.18, 4.55, 5.07, 5.87, 16.02, 18.00, 18.95.

Loop Detection / Context Issues: N/A — requires transcripts, empty for 7 days.

Experimental Analysis

Standard analysis only — no experimental strategy this run (random draw 40, threshold 30). Organic finding worth tracking: the burst-by-branch outcome split invalidates the blanket "bursts = action_required" rule; future metric = burst outcome segmented by branch approval state.

Actionable Recommendations

Process — (1) Approve first-party PRs faster: the entire gap between fix-pi (32%) and share-runner (8%) is approval state; pending branches turn every gate sweep into action_required. (2) Watch concentration: with 100% activity on 2 branches, one stalled PR dominates the daily rate.

System — (1) Fix conversation-log retrieval (HIGH): 7 days of empty logs/ blocks all behavioral analysis; longest-running unresolved risk. (2) Report burst outcome split by branch in standard metrics.

Tooling — Conversation transcript fetch (likely OAuth/permission, per 05-24 note) needed in all 50 sessions; 0/50 available for 7 days.

Historical Trends & Statistical Summary

• Completion: oscillating 44→2→0→46→22→28→14→26; no sustained recovery beyond 2 up-days.
• Avg duration: easing 3.88 → 3.01 → 2.23 min over 3 days.
• Concentration: 100% top-2 share, 2nd consecutive day.
• Data quality: degraded 7 straight days (no transcripts).

Next Steps

• Investigate/fix the 7-day conversation-log fetch failure (top priority)
• Expedite approval on share-runner-temp-env-var (Share RUNNER_TEMP with agent step in compiled lock.yml #35880) to unblock its retry wave
• Adopt branch-segmented burst reporting
• Follow-up analysis 2026-05-31
