🤖 Copilot Agent Session Analysis — 2026-07-03

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-07-03, 07:18–07:40Z (22.5-minute snapshot)
• Completion Rate: 4.0% (2 successful)
• Average Duration: 0.19 min (~11s); longest 8.62 min
• Experimental Strategy: Gate-Bundle Composition Divergence (GBCD) — roll=8

⚠️ Data quality: Conversation transcripts were empty for the 36th consecutive day. All metrics below are derived from CI/agent run metadata (status, conclusion, timing) — no behavioral, loop, or prompt-quality analysis of the agent's internal reasoning was possible this run.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	2 (4%)	↓ (8% on 07-02)
Failed / Abandoned	0 (0%)	→
action_required (CI gates)	46 (92%)	↑
In-progress	2 (4%)	→
Average Duration	0.19 min	↓
Median Duration	0.0 min	→
Loop Detection Rate	0 (0%)	→
Orphaned Branches	0 / 12 PRs (0%)	→

Completion continues the floor regime: 20% (07-01) → 8% (07-02) → 4% (07-03), sitting below both the 30-day mean (~13%) and 15-day mean (~10%). The saw-tooth oscillation pattern persists.

Success Factors ✅

1. Provenance inversion holds (5th+ consecutive observation): Both of today's successes are agentic workflow runs — PR Sous Chef (8.62 min) and Skillet (0.48 min), both on copilot/lint-monster-targeted-cleanup. Every action_required entry is a CI gate sweep. Success has never come from a gate firing.
   • Success rate: 100% of successes are agentic runs (2/2)
2. Copilot-assigned branches never orphan: 11 of 12 open PRs are Copilot-assigned; none exceeded the escalation threshold — ~39th consecutive healthy day.
3. Zero loops / zero failures: No abandoned sessions and no repetitive cycles detected in the run metadata.

Failure Signals ⚠️

1. Gate-sweep saturation (92% action_required): 46 of 50 sessions are zero-duration CI gate firings awaiting approval — the dominant volume driver, unchanged from the floor-regime pattern.
   • These are not agent failures; they are approval-gated infrastructure runs (median 0 min).
2. Branch concentration: 8 copilot/* branches; the top-2 (duplicate-code-fix @16 + duplicate-code-fix-runtime-cloning @13) account for 58% of all runs — a small number of PR-opens fan out most of the gate volume.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Prompt-quality assessment requires the agent's conversation transcript to gauge how the agent interpreted the task. Those transcripts have been unavailable for 36 consecutive days (auth/OAuth gap), so no prompt-clarity scoring is possible this run.

Proxy signal from run metadata: The two successful agentic runs (PR Sous Chef, Skillet) executed on a lint-cleanup branch with real work duration (8.62 min), consistent with the long-standing observation that scoped, well-defined cleanup tasks convert reliably. No low-quality-prompt evidence is observable from metadata alone.

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 12 open PRs (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.

• Max simultaneous gates on any copilot/* branch: 0 — all 3 in-progress runs are infrastructure workflows on main (Daily Workflow Updater, Copilot Session Insights, DataFlow PR & Discussion Dataset Builder).
• 11 of 12 open PRs are Copilot-assigned; the sole unassigned PR ([code-scanning-fix] Fix go/allocation-size-overflow (CWE-190): remove +1 in map allocation #43148, a fresh CodeQL fix opened at 08:00Z) has 0 active gates and does not qualify.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no recoverable orphaned CI capacity.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Sessions with loops: 0 (0%) — loop count has been 0 across the entire observation window.

Tool Usage

• Workflow frequency: Agentic Commands (10), Q (10), Doc Build - Deploy (6), Smoke CI (6), CGO (5), CWI (5).
• Core CI gate set = {Smoke CI, CGO, CWI, Doc Build - Deploy}.

Context Issues

• Not assessable — conversation transcripts unavailable (36th day).

Experimental Analysis

This run included experimental strategy: Gate-Bundle Composition Divergence (GBCD)

Approach: For each open copilot/* branch, measure which subset of the core CI gate set {Smoke CI, CGO, CWI, Doc Build - Deploy} actually fired, then compute the fraction of branches that diverge from the full 4/4 bundle.

Findings:

• Only 3 of 8 branches (37.5%) fired the full 4/4 core CI gate set — all three were code-change branches (duplicate-code-fix, duplicate-code-fix-runtime-cloning, deep-report-thread-context).
• Lint/doc branches fired 0/4 core gates, triggering lightweight agentic workflows instead (PR Sous Chef, Skillet, PR Description Updater, Label Closed PRs).
• update-checkout-specification fired 2/4 core gates + moderation workflows (AI Moderator, Content Moderation).
• GBCD = 62.5% (5/8 branches diverge from the full bundle).

Interpretation: This refines the earlier per_branch_gate_fanout pattern (06-26), which assumed a uniform ~8-workflow bundle per PR-open. Today's data shows the gate bundle is change-type-adaptive, not uniform — gate volume is a function of what changed, not merely that a PR opened. The "uniform bundle" was an over-generalization drawn from a code-heavy snapshot.

Effectiveness: Medium
Recommendation: Refine — track GBCD over time to see whether the change-type→gate-bundle mapping is stable, which would make gate_count a usable proxy for change type.

Actionable Recommendations

For Users Writing Task Descriptions

1. Scope tasks like the reliable cleanup runs: Today's only successes were on a targeted lint-cleanup branch. Narrow, well-bounded tasks continue to convert; keep task descriptions specific and file-scoped.

For System Improvements

1. Restore conversation-log ingestion (highest priority): 36 consecutive days without transcripts blocks all behavioral, loop, and prompt-quality analysis. This is the single largest analytical blind spot. (Impact: High)
2. Consider gate-approval batching: 92% of runs are approval-gated zero-duration sweeps. If gate approval can be batched per PR rather than per-workflow, the action_required volume (and reviewer overhead) would drop sharply. (Impact: Medium)

For Tool Development

1. Conversation-transcript fetch fix: Needed in ~50 sessions/day; blocks the core behavioral mission of this workflow.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate: 20% → 8% → 4% (07-01 → 07-03); below 30-day mean (~13%). Saw-tooth oscillation continues (peaks ~40% on 06-27, troughs 0–4%).
• Average duration: 0.73 → 0.19 min day-over-day — driven down by the high share of zero-duration gate sweeps.
• Orphan health: 0% for ~39 consecutive days.

📈 Session Trends Analysis

Completion Patterns

Completion has fallen for a second straight day (8% → 4%), extending the floor regime below the ~13% 30-day mean. The 06-27 peak (40%) remains an isolated spike within the persistent saw-tooth; failed/abandoned sessions stayed at zero, so the low rate reflects gate-sweep saturation rather than agent failure.

Duration & Efficiency

The distribution stays sharply bimodal: median duration is 0 every day (zero-duration CI gates) while a handful of long agentic runs pull the average up (8.62 min today). Only 4 of 50 sessions did real work, and loop count remained 0 across the entire window.

Next Steps

• Prioritize restoring conversation-log ingestion (36-day blind spot)
• Evaluate per-PR gate-approval batching to reduce 92% action_required volume
• Track GBCD across future runs to validate the change-type → gate-bundle mapping
• Schedule follow-up analysis next run (daily cadence)
