🤖 Copilot Agent Session Analysis — 2026-06-18

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-06-18 06:24–07:10Z (46-minute snapshot window)
• Completion Rate: 4% (2 successes)
• Average Duration: 0.5 min (median 0 min — dominated by 48 zero-duration gate runs)
• Experimental Strategy: None (standard run, roll = 40 ≥ 30)

Today was another pure gate-sweep snapshot: 48 of 50 runs are action_required GitHub Actions gate workflows captured pre-completion (created == updated, 0 duration). Only 2 agentic sessions completed — both succeeded and both ran ~12–13 min. Completion ticked up from yesterday's 0%, but the 7-day average (~11%) remains flat. Conversation transcripts were again empty (the logs/ directory contained no files), so behavioral/loop analysis remains blocked for the 18th+ consecutive day.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	2 (4%)	↑ (from 0% on 06-17)
Failed / action_required	48 (96%)	↓ (from 100%)
Average Duration	0.5 min	↑
Loop Detection Rate	n/a (no transcripts)	→
Context Issues	n/a (no transcripts)	→

📈 Session Trends Analysis

Completion Patterns

Completion remains in the familiar oscillating pattern: sharp peaks (06-10 at 40%, 06-13 at 38%) separating long stretches of single-digit gate-sweep days. Today's 4% is a marginal recovery off yesterday's zero, but well below the 30-day ceiling of 46%. The red action_required line dominating near 48–50 confirms most snapshots catch CI gate fan-out rather than finished agent work.

Duration & Efficiency

Average duration tracks completion closely — high on recovery days (peaks of 8.5 min on 05-23, 8.3 min on 06-08 when real agent work landed) and near zero on sweep days like today. Median stays pinned at 0 because the modal session is a zero-duration gate run. Loop counts are flat zero throughout, an artifact of absent transcripts rather than genuinely loop-free behavior.

Success Factors ✅

1. Agentic-workflow provenance: Both of today's successes came from agent-driven workflows — "Running Copilot cloud agent" (12.8 min) and "Addressing comment on PR Improve Copilot harness classification for opaque exitCode=1 failures #39959" (12.3 min) — not from CI gate workflows.

   • Success rate: 2/2 agentic sessions succeeded
   • Reinforces copilot_cloud_agent_reliability (cloud agent remains a consistent success source).

2. Copilot-assigned branches stay healthy: All 8 open PRs have a Copilot agent assigned; none became orphaned.

   • Success indicator: 0 orphans, consistent with inverse_gate_count_to_conclusiveness.

3. Multi-minute work correlates with completion: Both successes ran 12+ min, matching the historical pattern that genuine completions cluster well above the sub-minute gate-sweep floor.

Failure Signals ⚠️

1. Gate-sweep saturation: 48/50 runs are action_required with 0 duration — the snapshot keeps landing during CI gate fan-out, not at task completion.

   • Failure-shaped rate: 96% (but this is a sampling artifact, not true task failure).

2. Branch concentration of gate load: Top-3 branches account for 64% of all runs (feature-ai-authorship-footer 11, fix-extract-base-branch-regex 11, clean-up-gh-aw-containers 10).

   • Heavy per-branch gate footprint raises orphan risk if agents were ever unassigned (they currently are not).

3. No transcript visibility: 18th+ consecutive day with empty conversation logs — genuine loop/context-confusion failures cannot be observed.

Prompt Quality Analysis 📝

Note on data availability

This snapshot exposes only workflow-run metadata (name, status, conclusion, branch, timestamps) — no task prompts or agent transcripts. Prompt-quality scoring therefore cannot be computed for 06-18. The two completed agentic workflows ("Running Copilot cloud agent", "Addressing comment on PR #39959") both reached success, which is weakly consistent with the historical finding that agent-assigned, scoped tasks complete more reliably than ad-hoc gate triggers — but this cannot be verified against prompt text today.

Workflow-name distribution (proxy for task type)

• Q: 11 · Agentic Commands: 10 · Smoke CI: 8 · Doc Build – Deploy: 4 · Label Closed PRs: 4 · PR Description Updater: 4 · CJS: 3 · CGO: 2 · CWI: 2 · agentic successes: 2

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 8 open PR branches (0%)
• Historical Baseline: ~40% orphaned rate
• Status: ✅ NORMAL (well below the 50% elevated-waste threshold)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today.

All 8 open PRs (#40001, #40000, #39998, #39997, #39995, #39959, #39927, #39830) have a Copilot agent assigned. The only in-progress workflow runs (2) are both on main — the Failure Investigator and this Session Insights workflow — so no PR branch is carrying an active, agent-less gate sweep.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no recoverable orphaned CI capacity.
• The recurring waste pattern (zero-duration gate fan-out) is sampling noise here, not agent-less orphaning.

Notable Observations

Loop Detection

• Sessions with loops: 0 detected — but only because conversation transcripts are unavailable (18th+ day). Treat as "unmeasured," not "loop-free."

Tool Usage

• Not observable without transcripts. Only run-level metadata (workflow name, status, conclusion, branch) is available.

Context Issues

• Not observable without transcripts.

Data Quality

• Primary blocker: logs/ directory empty — no {session}-conversation.txt files delivered. This is the longest-standing unresolved risk in this analysis stream.

Experimental Analysis

Standard analysis only — no experimental strategy this run (random roll = 40, threshold < 30 for experimental).

Actionable Recommendations

For Users Writing Task Descriptions

1. Prefer scoped, agent-assigned tasks: Today's only completions were agent-driven workflows that ran 12+ min. Ad-hoc gate triggers do not produce "completions" in this metric.
2. Keep PRs agent-assigned: Every assigned PR avoided orphaning. Leaving a high-gate branch agent-less is the single biggest orphan-risk lever.

For System Improvements

1. Restore conversation-log delivery — Potential impact: High. 18+ days without transcripts blocks all behavioral analysis (loops, tool usage, context confusion, prompt quality).
2. Adjust snapshot timing or status filtering — Potential impact: Medium. The snapshot consistently lands during CI gate fan-out, inflating action_required to ~96% and depressing the apparent completion rate. Sampling closer to run completion, or excluding pre-completion gate runs, would yield a truer success metric.

For Tool Development

1. Transcript fetch reliability — needed in ~every session; the conversation-log fetch path has failed for 18+ consecutive days and should be prioritized for a fix.

Historical Trends and Statistical Summary

Trends Over Time

• Completion-rate trend: Oscillating, no sustained direction. Recent 7-day avg ~11.1% vs prior 7-day ~12.0% (flat). 30-day range 0–46%.
• Average-duration trend: Tracks completion; spikes only on real-work days (peaks 8.5 / 8.3 / 6.4 min), near-zero on sweep days.
• Orphan-rate trend: Stable at 0% for recent snapshots — consistently healthy vs the ~40% baseline.

Next Steps

• Prioritize the conversation-log fetch fix — behavioral analysis has been blocked 18+ days
• Consider snapshot-timing/status-filter change to deflate the gate-sweep action_required skew
• Keep monitoring orphan rate (currently 0%, healthy)
• Follow-up analysis next daily run
