🤖 Copilot Agent Session Analysis — 2026-10-19

⚠️ Primary Finding: Session Data Pipeline Regression

This run's pre-fetched data (/tmp/gh-aw/agent/session-data/sessions-list.json, 50 entries) does not contain Copilot coding-agent sessions. All 50 entries are CI gate / check-run workflows — CGO, CWI, CJS, Work Queue Compilation Integration, Doc Build - Deploy, Code scanning AI findings on PR #..., Agentic Commands — spread across just 2 PR branches. Correspondingly, 0 of 50 {run_id}-conversation.txt transcript files were present in /tmp/gh-aw/agent/session-data/logs/.

This is worse than the recent trend (prior worst was 1–3/50 logs available, see Historical Trends below) and appears to be a genuine regression in the copilot-session-data-fetch shared module's run-selection logic, not a one-off empty day. Recommended action: review that module's workflow-run filter to confirm it targets actual Copilot coding-agent runs rather than CI gate/check workflows.

Because of this, the deep behavioral analysis this workflow is designed to produce — tool usage patterns, turn-by-turn token efficiency, loop detection, prompt-quality correlation, context-confusion detection — could not be performed this run. The metrics below are metadata-only continuity figures computed from the CI-gate-run population (for trend comparability with prior days), not true agent-session behavioral data.

Executive Summary

• Sessions Analyzed: 50 (CI gate/check-run workflows — not Copilot agent sessions; see finding above)
• Analysis Period: 2026-10-19, 01:46:39Z–05:47:40Z (~241 min)
• Conversation Logs Available: 0/50 (0%)
• Raw Completion Rate: 66.0% (33 success / 10 action_required / 7 failure)
• Experimental Strategy: None (standard run, roll=30/100)

Key Metrics

Metric	Value	Trend
Total Runs Fetched	50	→
Successful	33 (66.0%)	↓ (vs 68.0% on 10-18)
Failed / Action Required	17 (34.0%)	↑
Unique Branches	2	↓ (narrowest on record; prior narrowest was 3 on 10-18)
Conversation Logs Available	0 (0%)	↓ (worst on record; prior worst 1-3/50)
Orphan Rate	0.0%	→ (47th consecutive healthy day)

Provenance Breakdown (metadata-only, not behavioral)

• Bot-driven successes: 31/33 = 93.9% — a new record high (previous record 97.0% on 2026-10-14, though that figure covered a different run population).
• True-agentic channel: "Addressing comment on PR Add declarative webhook triggers and versioned CAO subscriptions #69772" and "Addressing comment on PR Recognize merged base ancestors when the base tip advances #69998" — 2/2 = 100% resolved.
• Ambiguous: "Squad Implement Worker" (1 run, action_required) — excluded from both buckets, provenance unclear.
• Branch concentration: copilot/add-declarative-webhook-triggers 35/50 = 70.0% (dominant), copilot/fix-push-to-pull-request-branch-again 15/50 = 30.0%. Only 2 branches total, narrower than any prior recorded day.
• Duration: mean 8.0 min / median 0.0 min. 40/50 entries share identical created_at/updated_at timestamps (instant CI-gate fires), so this is not representative of real agent session duration.

📈 Session Trends Analysis

Completion Patterns

Raw completion held roughly flat (66.0% vs 68.0% on 2026-10-18), continuing the recovery from the 2026-10-17 trough (18.0%). However, this reading should be read with caution: it reflects CI-gate/check-run outcomes for this run, not genuine agent-session completions, because of the data-fetch issue described above.

Duration & Efficiency

Duration figures have been volatile over the last 30 days (1.2 min to 18.5 min mean), largely driven by which workflow types dominate the fetched population on a given day rather than genuine session-complexity changes. Per-day loop/retry counts are not tracked historically in cache memory, so that series is omitted from the chart rather than fabricated — this is a gap worth closing in the cache schema.

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 PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (30-day mean over 30 recorded days)
• Status: NORMAL (47th consecutive healthy day)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. Only 1 in-progress workflow run existed across all open PRs at check time (max gate_count/branch = 1), well below the ≥5 threshold.

CI Waste Estimate

Not applicable — no escalation candidates today.

What Couldn't Be Analyzed This Run

Due to the 0/50 conversation-log availability, the following standard analysis strategies could not be executed:

• Loop Detection — no turn-by-turn data to detect repetitive cycles
• Tool Usage Patterns — no tool.execution_start/tool.execution_complete lines to analyze
• Prompt Quality Analysis — no user.message turns to assess
• Context Confusion Detection — no assistant reasoning to inspect
• Token Efficiency — no assistant.usage lines with model/token data
• Experimental Strategy — skipped in favor of documenting the data regression as the actionable finding for this run

Actionable Recommendations

For System Improvements

1. Fix copilot-session-data-fetch run selection: Today's fetch returned CI gate/check-run workflows (CGO, CWI, CJS, Work Queue Compilation Integration, Doc Build - Deploy, Code scanning AI findings, Agentic Commands) instead of actual Copilot coding-agent session runs. This has been a partial problem for weeks (1–3/50 logs on a "good" day per cache history) but today it's total (0/50) and the run population itself is wrong.
   • Potential impact: High — this workflow cannot fulfill its core mission (behavioral session analysis) until fixed.
2. Track loop/retry counts per day in cache memory: session-analysis/history.json does not currently store a daily loop-count field, forcing the duration chart to omit that series rather than fabricate it.
   • Potential impact: Medium — needed for the "Session Duration & Efficiency" chart to be complete.

For Tool Development

1. Run-population filter/validator: A lightweight sanity check (e.g., workflow name allowlist/denylist, or presence of cca-engine/events.jsonl artifacts) in the fetch module would allow this workflow to self-detect a wrong-population day and raise missing_data immediately instead of silently analyzing the wrong dataset.
   • Frequency of need: Recurring (near-daily partial degradation, now a full regression)

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: 50.0% (10-15) → 50.0% (10-16) → 18.0% (10-17, trough) → 68.0% (10-18) → 66.0% (10-19). Volatile, no sustained directional trend over the last 5 days.
• Conversation log availability trend: 3/50 (10-16) → 1/50 (10-17) → 1/50 (10-18) → 0/50 (10-19, new low). This is the concerning trend — behavioral-analysis coverage is degrading toward zero, not recovering.
• Orphan rate: 0.0% for 47 consecutive recorded days — consistently healthy, unaffected by the session-data issue since it uses an independent gh api data source.

Next Steps

• Investigate and fix the copilot-session-data-fetch shared module's run-selection logic (it's returning CI gate/check-run workflows instead of Copilot agent sessions)
• Add a loop/retry-count field to the daily cache-memory history schema
• Add a run-population sanity check so future runs can missing_data immediately on a wrong-population day
• Re-run full behavioral analysis once the data pipeline is fixed
