🤖 Copilot Agent Session Analysis — 2026-06-15

Executive Summary

• Sessions Analyzed: 50 · Period: 2026-06-14 23:35Z → 06-15 02:08Z
• Completion Rate: 12% (6 success / 44 action_required)
• Average Duration: 1.48 min (median 0 — strongly bimodal)
• Experimental Strategy: cross_session_branch_lifecycle
• Data Quality: ⚠️ Metadata-only — agent transcripts unavailable for the 23rd+ consecutive day (OAuth/log-fetch failure). Loop/tool/context/prompt analyses cannot run; all metrics derive from CI/infra metadata.

Failed Sessions	0 (0%)	→
Pending / Gate-sweep	44 (88%)	↓ (from 46)
Average Duration	1.48 min	↑ (from 1.01)
Median Duration	0.0 min	→
Loop Detection	N/A (no transcripts)	→
Orphaned-branch rate	0%	→ (healthy, ~25th day)

📈 Session Trends Analysis

Completion Patterns

Completion ticked up from 8% (06-14) to 12% (06-15), but stays below the 7-day average of 17.1% (06-09...06-15: 0, 40, 18, 4, 38, 8, 12). The saw-tooth recovery_regression_oscillation persists — today is a low-mid rung between the 40%/38% spikes (06-10/06-13), not a sustained recovery.

Duration & Efficiency

Purely bimodal: only the 6 successful sessions had nonzero duration; the other 44 were 0-duration gate sweeps, pinning median at 0 while the 1.48-min mean is driven by a few long cloud-agent/comment runs.

Success Factors ✅

1. Copilot cloud-agent reliability: 2/2 "Running Copilot cloud agent" succeeded again (15.97, 15.20 min) — the most consistent success source across runs.
2. Comment-addressing completes: both "Addressing comment on PR" succeeded (feat: supertonic TTS standalone dispatcher #39164 21.78 min, Run safe-outputs MCP in the gh-aw node container #39100 14.43 min).
3. One real success per active branch: every branch landed ≥1 success amid gate noise (see Experimental).

Failure Signals ⚠️

1. Gate-sweep dominance (88%): 44/50 are 0-duration action_required CI gates awaiting approval — not task failures, but they swamp the signal.
2. No sustained recovery: each uptick reverts within 1–2 days (oscillation, not trend).
3. success_duration_floor partial break: trivial Haiku Printer (0.23 min) and Code Review (6.25 min) succeeded sub-8min; the ≥8-min floor holds only for cloud-agent/comment-addressing provenance.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Prompt-level analysis requires agent transcripts, unavailable this run (23rd+ consecutive day). Metadata exposes no task descriptions. We can only infer from provenance: success concentrates in two high-context workflow types — Running Copilot cloud agent and Addressing comment on PR #NNNN — both carrying scoped, specific context. The 0-duration gate sweeps carry no agent prompt at all. No high/medium/low breakdown is possible until transcript access is restored.

Orphaned Branch Escalation Alerts 🚨

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

• Orphaned Branches Today: 0 / 6 active copilot/* branches (0%)
• Historical Baseline: ~40% · Status: ✅ NORMAL (below the 50% elevation threshold)

Escalation Candidate Details

✅ No orphaned branches exceed the threshold today. At analysis time only 2 in-progress runs existed, both on main (housekeeping + this workflow). No copilot/* branch had an active gate sweep, so none can be orphaned. Of 13 open PRs, all 6 copilot/* PRs (#39300, #39282, #39266, #39164, #39156, #39100) have Copilot assigned; the other 7 are housekeeping PRs with 0 gate firings.

CI Waste Estimate: 0 gate-hours ≈ 0 CI-minutes wasted — ~25th consecutive healthy day vs the 40% baseline.

Notable Observations

Timing, Branch Concentration & Transcript-gated metrics

• Loop / Tool / Context analysis: N/A — all transcript-derived; unavailable.
• Timing: 3 clusters — 23:35–23:58Z (06-14), dominant 00:04–00:21Z burst (06-15), 02:08Z tail; consistent with synchronized CI gate sweeps, not independent agent activity.
• Branch concentration: add-share 21 (42%) · add-copilot-sdk-idle-watchdog 10 (20%) · add-custom-validation 9 (18%) — top-3 = 80%. All 5 branches copilot/*.

Experimental Analysis

Strategy: cross_session_branch_lifecycle (Cross-Session Learning — per-branch volume vs success density).

Branch	Sessions	Successes	Per-branch completion
copilot/add-share-agentic-workflow	21	1	4.8%
copilot/add-copilot-sdk-idle-watchdog	10	1	10.0%
copilot/add-custom-validation-safe-outputs	9	1	11.1%
copilot/configure-safe-outputs-mcp-server	7	2	28.6%
copilot/custom-validation-safe-outputs	3	1	33.3%

Findings: Every branch yields ~1 substantive success regardless of session count — the "real work" per branch is a single cloud-agent/comment run surrounded by gate noise. Per-branch completion is inversely correlated with gate footprint: the busiest branch (21 sessions) has the lowest completion (4.8%); the lightest (3 sessions) the highest (33.3%). High session counts reflect gate-sweep volume, not productivity. Confirms the existing branch_symmetric_success_distribution pattern.

Effectiveness: Medium. Recommendation: Keep — adopt a gate-normalized completion metric (successes ÷ substantive sessions).

Actionable Recommendations

For Users

1. Favor PR-thread / cloud-agent entry points — success concentrates there; prefer over ad-hoc triggers.
2. Keep tasks branch-scoped and small — lighter branches show higher per-branch completion.

For System (Impact)

1. Restore conversation-transcript access (High): 23+ metadata-only days block all behavioral analysis — the single biggest blocker to this workflow's value.
2. Report a gate-normalized completion metric (Medium): raw % is dominated by 0-duration gate sweeps.

For Tool Development

1. Transcript-fetch resilience (~50 sessions/day, 23+ days): fallback auth or cached-transcript path so behavioral analysis degrades gracefully.

Statistical Summary

Total Sessions:        50
Successful:            6 (12%)
Failed/Abandoned:      0 (0%)
Pending (gate-sweep):  44 (88%)
Avg Duration:          1.48 min
Median Duration:       0.00 min
Longest:               21.78 min (Addressing comment on PR #39164)
Shortest nonzero:      0.23 min  (Haiku Printer)
Loop/Context/Tool:     N/A (no transcripts, day 23+)
Orphaned Branches:     0 / 6 active copilot/* (0%)
7-day completion avg:  17.1%

Next Steps

• Prioritize restoring agent transcript access (blocks behavioral analysis 23+ days)
• Adopt a gate-normalized completion metric
• Monitor the completion saw-tooth for sustained multi-day recovery
• Follow-up analysis tomorrow (daily cadence)
