🤖 Copilot Agent Session Analysis — 2026-10-23

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-10-23, 04:48:42–06:06:03 UTC (~78 min window)
• Completion Rate: 46.0%
• Average Duration: 14.34 min (mean) / 4.31 min (median) — CI-gate-run wall-clock time, not true agent think-time (see data caveat below)
• Experimental Strategy: None (standard run; roll=32/100, threshold <30)

⚠️ Data pipeline caveat: For the 6th day in the last 7 recorded, 0/50 conversation/event-log transcripts were fetched (/tmp/gh-aw/agent/session-data/logs/ is empty). The 50 sampled runs are CI-gate, review-bot, and code-scanning workflows (CGO, CWI, Work Queue Compilation Integration, Stale Lock Files, CJS, Code scanning AI findings, Squad/Squad Implement Worker, Agentic Commands, plus single-run review bots), not true Copilot coding-agent implementation sessions. Turn-by-turn behavioral analysis (tool usage, token efficiency, loop detection, prompt-quality scoring) was not possible today. All metrics below are computed from run metadata (sessions-list.json) only, consistent with the methodology used on prior data-pipeline-failure days (see Notable Observations).

Key Metrics

Metric	Value	Trend vs 2026-10-22
Total Sessions	50	→ (fixed sample size)
Successful Completions	23 (46.0%)	↑ (+12 vs 11, +24.0pts)
Failed/Abandoned/Action-Required	27 (54.0%: 18 failure, 8 action_required, 1 cancelled)	↓ (-12 vs 39, -24.0pts)
Average Duration	14.34 min	↑ (vs 2.41 min)
Loop Detection Rate	N/A — unavailable	— (no conversation logs)
Context Issues	N/A — unavailable	— (no conversation logs)

Success Factors ✅

Patterns associated with today's "successful" runs — read with the provenance caveat below, since none of today's successes are true agentic task completions:

1. Core CI-gate green sweeps: CGO, CWI, Work Queue Compilation Integration, Stale Lock Files, CJS, Work Queue Stress all posted mixed success/failure on the two active branches.

   • Success rate: 18/30 (60.0%) of core-CI-gate runs
   • Example: Work Queue Compilation Integration succeeded 4/6 times on copilot/add-smoke-test-work-queue-workflow.

2. Code-scanning findings workflows: fully green today.

   • Success rate: 4/4 (100%) of Code scanning AI findings on PR #71340 runs (1 additional run on PR Fall back to pinned Copilot CLI when live compatibility targets lack trusted checksums #71339 was cancelled, excluded).

3. Narrow branch concentration: only 2 unique branches produced all 50 runs (58.0% / 42.0% split), ties the narrowest-spread record set on 2026-10-19 and 2026-10-21 — concentrated pushes tend to correlate with cleaner, more legible gate sweeps than multi-branch noisy days.

Failure Signals ⚠️

1. Zero true-agentic volume: no run in today's 50-sample population matches a true coding-agent task-completion pattern (e.g. "Addressing comment on PR #N", "Running Copilot cloud agent"). This is only the 3rd zero-volume true-agentic day on record (previous: 2026-09-17, 2026-10-20).

   • Failure rate: 100% of the true-agentic channel is absent, not merely failing.

2. Agentic Commands / Squad gate cluster stuck at action_required: 8/8 runs (Agentic Commands ×3, Squad ×3, Squad Implement Worker ×2) report action_required, 0% resolved.

   • Failure rate: 8/8 (100%) non-resolving.

3. Long-tail runtime outliers: 8 of 50 runs (CGO, CWI, Work Queue Compilation Integration, Stale Lock Files) ran 63.7–73.4 minutes each, far above the rest of the population (mostly <6 min or instant). These 8 runs alone account for most of today's inflated 14.34 min mean (vs 2.41 min on 10-22).

   • Failure rate: n/a (these are duration outliers, not conclusion failures) — flagged as a diagnostic anomaly worth checking for stuck/hung CI-gate workers.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Not assessable today: sessions-list.json carries only workflow run metadata (name, branch, conclusion, timestamps) with no task-description or prompt text, and the conversation-log pipeline that would normally supply prompt content returned 0/50 files. This section is skipped for the 6th time in the last 7 recorded days pending a pipeline fix — see Notable Observations.

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 6 open PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (30-day mean over 30 recorded days)
• Status: NORMAL (0.0% today vs 0.0% baseline; well under the >20pt-elevation / >50% fallback thresholds)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. Max simultaneous gate count observed was 2 (on main), well below the 5-gate threshold; only 3 in-progress runs existed across 6 open PRs at check time.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no escalation candidates, no estimable waste.
• Recoverable capacity: N/A — this is the 51st consecutive healthy day with 0 escalations.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Sessions with loops: N/A — unavailable without turn-by-turn conversation logs.
• Average loop count: N/A
• Common loop patterns: N/A

Tool Usage

• Most used tools: N/A — tool-call data requires conversation/event logs, none fetched today.
• Tool success rates: N/A
• Missing tools: N/A

Context Issues

• Sessions with confusion: N/A
• Common confusion points: N/A
• Clarification requests: N/A

Data Pipeline Status (recurring issue)

• 0/50 conversation/event-log transcripts fetched today — the 6th day in the last 7 recorded with zero logs (prior 7 days: 10-17 partial, 10-18 0, 10-19 0, 10-20 0, 10-21 3/50 partial recovery, 10-22 0, 10-23 0).
• The sampled run population continues to be CI-gate/review-bot/code-scanning workflows rather than Copilot coding-agent implementation sessions, a persistent mismatch between what this workflow intends to sample and what the upstream fetch step returns.
• Provenance inversion — new record tie: 23/23 successes (100%) are bot-driven (18 core-CI-gate + 4 code-scanning + 1 review-bot/advisory), tying the all-time-high bot-driven share set on 2026-10-20. Combined with the zero true-agentic volume noted above, today is a clean instance of the channel_isolation-adjacent pattern: one channel (core-CI-gate) dominates, true-agentic is silent.
• Recommendation: this is now a 7-week-plus recurring condition (47/51 recorded days affected per cache memory). It warrants investigation as a standing infrastructure issue in the copilot-session-data-fetch shared module rather than being re-flagged daily — see Actionable Recommendations.

📈 Session Trends Analysis

Completion Patterns

Completion rate swung from 22.0% (10-22, 2nd-lowest on record) back up to 46.0% today, landing almost exactly on the 50-day prior mean (36.4%) — a reversion toward the middle of the historical 4–80% range rather than a sustained trend in either direction. The last 5 recorded days alone span 22–80%, underscoring how volatile this metric is while the true-agentic channel remains silent or near-silent.

Duration & Efficiency

Mean duration jumped to 14.34 min (median 4.31 min) from 10-22's 2.41/0.0 min, driven almost entirely by 8 outlier runs (CGO/CWI/Work Queue Compilation Integration/Stale Lock Files) that each ran 64–73 minutes — a pattern worth checking for stuck or queued CI workers rather than genuine agent work. Loop/retry counts could not be overlaid this period since conversation logs (the only source for loop detection) were unavailable for all 50 sampled runs.

Experimental Analysis

No experimental strategy this run (roll=32/100, threshold <30 not met) — standard analysis only.

Actionable Recommendations

For Users Writing Task Descriptions

Not assessable this run: no prompt text was available in either sessions-list.json or the (empty) conversation logs. Deferred until the data pipeline is fixed.

For System Improvements

1. Fix the copilot-session-data-fetch conversation-log pipeline: 47 of the last 51 recorded days have returned 0 (or near-0) conversation/event-log files, forcing every analysis onto CI-gate-run metadata instead of actual Copilot coding-agent sessions. This is the single highest-impact fix available — it would unblock loop detection, tool-usage analysis, token-efficiency tracking, and prompt-quality scoring, none of which have been possible for over 7 weeks.

   • Potential impact: High

2. Investigate the long-tail CI-gate runtime outliers: 8/50 runs today took 64–73 minutes versus a population median near 0–4 minutes. If this recurs, it may indicate queued/stuck runners rather than genuine work, inflating duration metrics and potentially delaying PR feedback.

   • Potential impact: Medium

For Tool Development

1. Run-population filter for this analysis workflow: the fetch step consistently returns CI-gate/review-bot/code-scanning runs rather than Copilot coding-agent implementation runs. A filter (e.g. by workflow name or a copilot-agent label) would make the ~50-session sample actually representative of agentic task completions.
   • Frequency of need: Affects essentially every recorded day (47+/51)
   • Use case: Restore the intended turn-by-turn behavioral analysis this report format is designed around.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: Volatile/saw-tooth across the last 5 recorded days (72% → 80% all-time-high → 22% 2nd-lowest → 46% today), with no sustained directional trend. 50-day prior mean: 36.4% (range 4–80%).
• Average duration trend: Also volatile and dominated by whichever workflow population happens to be sampled that day (instant CI-gate fires vs long-running review-bots vs today's runtime outliers); not representative of true agent session duration while conversation logs remain unavailable.
• Quality improvement: Not assessable — prompt-quality and loop-detection metrics require conversation logs, unavailable for 47+/51 recorded days.

Next Steps

• Review recommendations with team
• Prioritize investigating/fixing the copilot-session-data-fetch conversation-log pipeline (47+/51 days affected)
• Spot-check the 4 long-running CI-gate workflows (CGO, CWI, Work Queue Compilation Integration, Stale Lock Files) for stuck/queued runners
• Schedule follow-up analysis tomorrow (2026-10-24)
