🤖 Copilot Agent Session Analysis — 2026-08-14

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-08-14, 05:54–06:54 UTC (~1-hour window)
• Completion Rate: 6% — down sharply from 18% (08-13) and 22% (08-12); 2nd-lowest of the 10 sampled days on record (only 07-03 at 4% and 06-29 at 2% were lower)
• Average Duration: 0.95 min (all sessions, median 0 min); 11.9 min mean / 9.4 min median on the 4 sessions that actually executed
• Experimental Strategy: Review-Bundle Diversity Index (RBDI) — 30%-probability roll landed at 19/100

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	3 (6%)	↓↓ (from 18%, 22%)
Action Required / Gate-blocked	46 (92%)	↑
In Progress	1 (2%)	→
Average Duration (all)	0.95 min	↓ (from 2.02 min)
Executed-run Mean / Median	11.9 min / 9.4 min	↑ (highest yet)
Loop Detection Rate	not measurable	→
Context Issues	not measurable	→
Orphaned-branch escalations	0	→

Data-quality caveat: conversation transcripts ({run_id}-conversation.txt) were empty again — the 3rd consecutive sampled day without behavioral logs. All metrics below are derived from run metadata (name, conclusion, timing, branch) only; tool-usage, loop, and prompt-quality analysis are not possible until log collection is restored.

Success Factors ✅

1. Targeted "Addressing comment on PR" workflows remain the highest-converting path: PR Harden Copilot api-proxy startup: verify listener accept readiness and absorb first-request ECONNREFUSED #52619 (13.3 min, fix-copilot-engine-proxy-connections) and PR Detect sandbox shell-expansion guard rejections; steer agents toward jq -Rs for multi-line safeoutputs bodies #52578 (28.6 min, aw-failures-fix-sandbox-guard) both completed — this pattern (provenance_inversion) has now held for 3 straight sampled days.
2. Direct cloud-agent invocation over gate bundles: "Running Copilot cloud agent" completed in 5.6 min on deep-report-add-gh-aw-detection — the 3rd of today's 3 successes.
3. Narrow, single-purpose branches converted; the broadest one did not — see Experimental Analysis below.

Failure Signals ⚠️

1. Zero-duration gate stubs dominate: 46/50 runs (92%) show 0.0-minute duration — these are approval-gated CI checks parked in action_required, not executed failures, but they make up the bulk of the "completion rate" denominator.
2. Full reviewer-roster branch converted at 0%: copilot/refactor-errorutil-duplicates fired 11 runs across 10 distinct specialized workflows (Agentic Commands ×2, CGO, CWI, Design Decision Gate, Impeccable Skills Reviewer, Matt Pocock Skills Reviewer, PR Code Quality Reviewer, PR Data Prefetch, Ponytail Reviewer, Test Quality Sentinel) — the heaviest and most diverse gate load of the day, with zero completions.
3. Sharpest single-day drop in the tracked history: 18%→6% reverses the brief two-day recovery (22%→18%) and returns to floor-regime territory.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Not derivable this run — conversation logs were empty for all 50 sessions (3rd consecutive sampled day). Prompt-quality clustering requires the {run_id}-conversation.txt transcripts; only run metadata (name/conclusion/timing/branch) was available.

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 24 open PRs (0%)
• Historical Baseline: ~40% orphaned rate (long-run reference); this repo's sampled days have consistently landed at ~0%
• Status: NORMAL

Escalation Candidate Details

Only 2 workflow runs were in-progress across the entire 6-hour lookback window — well below the ≥5-gate escalation threshold — so no branch qualified for evaluation. All 24 open PRs with active copilot/* branches are assigned to Copilot (and pelikhan); no unassigned branch carried any active gate load.

✅ No orphaned branches exceed the escalation threshold today.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no qualifying candidates
• Recoverable capacity: n/a

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Sessions with loops: not measurable (no conversation logs)

Tool Usage

• Most used tools: not measurable (no conversation logs)

Context Issues

• Sessions with confusion: not measurable (no conversation logs)

Branch fragmentation

• 11 unique copilot/* branches fired activity today — the most fragmented sampled day yet (prior days ranged 5–8 branches). Gate counts per branch: refactor-errorutil-duplicates 11, aw-failures-fix-sandbox-guard 8, deep-report-add-gh-aw-detection 7, fix-copilot-engine-proxy-connections 6, aw-failures-go-logger-enhancement 5, remaining 6 branches ≤3 each.

Experimental Analysis

This run included experimental strategy: Review-Bundle Diversity Index (RBDI)

RBDI measures, per branch, the ratio of distinct workflow names to total runs — a composition/diversity lens, complementing prior fan-out metrics that only measured volume (runs) or refire ratio.

Branch	Runs	Distinct workflows	RBDI	Completions
refactor-errorutil-duplicates	11	10	0.91	0
aw-failures-go-logger-enhancement	5	4	0.80	1 (in-progress, null conclusion)
deep-report-add-gh-aw-detection	7	5	0.71	1
aw-failures-fix-sandbox-guard	8	5	0.63	1
fix-copilot-engine-proxy-connections	6	3	0.50	1
aw-failures-fix-log-capture	3	1	0.33	0

Findings:

• The highest-RBDI branch (0.91) drew the complete specialized-reviewer roster — design, code-quality, skills ×2, test-quality, data-prefetch, and general review bots — all in a single wave, and was the only heavy-gate (≥5 runs) branch with zero completions.
• The lowest-RBDI branch (0.33) was a pure refire of one workflow (Agentic Commands ×3) — narrow retry churn, not broad review coverage — also 0 completions, so RBDI alone doesn't cleanly separate outcomes at the low end.
• Mid-range RBDI branches (0.5–0.8) each converted at least one exec run.

Effectiveness: Medium (plausible signal, but only 6 branches had >2 runs today — too small a sample to claim RBDI predicts non-completion)
Recommendation: Refine — recompute across the next several sampled days to see whether high-RBDI branches systematically under-convert, or whether today's correlation was coincidental.

Actionable Recommendations

For Users Writing Task Descriptions

1. Prefer targeted follow-up requests over broad ones: The only 3 completions today were narrowly-scoped ("address this PR comment", direct cloud-agent invocation), consistent with 3 straight sampled days of the same pattern.
2. Expect delayed approval gates on large refactors: A single large refactor branch drew 10 distinct specialized reviewer bots simultaneously — budget for action_required approval steps rather than treating them as failures.

For System Improvements

1. Investigate the persistent provenance-inversion pattern: Gate-type workflows (Agentic Commands, CJS, CWI, CGO, moderators, skills reviewers) have not produced a single success conclusion across 3 consecutive sampled days (0/126 combined). Confirm whether this is by design (approval-gated, awaiting manual dispatch) or a workflow misconfiguration — this is the single largest driver of the low daily completion percentage.
   • Potential impact: High
2. Restore conversation-log collection: 3rd straight day of metadata-only fallback. Loop detection, tool-usage patterns, and prompt-quality analysis remain entirely unavailable.
   • Potential impact: High

For Tool Development

• No missing-tool signal detectable this run — requires conversation logs to assess tool-call patterns.

Historical Trends and Statistical Summary

📈 Session Trends Analysis

Completion Patterns

Completion rate fell to 6% today, the sharpest single-day drop in the tracked history and a reversal of the brief 22%→18% mini-recovery. The chart's sampled-day gaps (largest: 07-08 to 08-12, 35 days) mean this is not a continuous 30-day trend — it's 10 discrete snapshots spanning 2026-06-23 to 2026-08-14, oscillating in a wide 2–54% band around a ~13% historical mean.

Duration & Efficiency

Overall mean/median duration stayed near the historical floor (most sessions are instant 0-duration gate stubs), but the executed-runs-only view tells the opposite story: mean (11.9 min) and median (9.4 min) execution time hit their highest levels across all sampled days — real agent work is taking longer per run even as fewer runs execute at all.

Trends Over Time

• Completion rate trend: Volatile saw-tooth pattern, no sustained direction. Trailing sampled values: 20→40→10→2→4→54→16→8→22→18→6.
• Average duration trend: All-session average continues to track near-zero (gate-stub dominated); executed-run average has climbed for 3 straight sampled days (9.23→11.23→11.90 min mean).
• Quality improvement: Not assessable without conversation logs; only CI/infra-metadata trends available.

Next Steps

• Review recommendations with team, particularly the persistent provenance-inversion pattern (0 gate-workflow successes across 3 sampled days)
• Prioritize restoring conversation-log collection — behavioral analysis has been unavailable for 3 consecutive sampled days
• Track Review-Bundle Diversity Index (RBDI) across the next several sampled days to validate or refute today's signal
• Schedule follow-up analysis for the next sampled day
