🤖 Copilot Agent Session Analysis — 2026-06-20

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-06-20 05:58–06:22Z (24-minute burst)
• Completion Rate: 0% (0 successful conclusions)
• Average Duration: 0.0 min (all 50 sessions zero-duration)
• Experimental Strategy: Gate Footprint Signature Classification (this is an experimental run, roll=20)

Data quality note: Conversation transcripts were unavailable for the 27th+ consecutive day (OAuth fetch failure). All findings below are derived from CI/infrastructure run metadata only — no behavioral, loop, or context analysis from agent internal monologue was possible this run.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	0 (0%)	↓ (from 6% on 06-19)
Failed / action_required	50 (100%)	↑
Average Duration (timed)	0.0 min	↓
Loop Detection Rate	0 (n/a — no substantive sessions)	→
Orphaned Branches	0 of 10 active PRs (0%)	→ (healthy)

Today is a pure gate-sweep, zero-completion day — the 4th zero-completion day in the trailing 15-day window. The recent-7-day completion average has fallen to 6.0%, down sharply from the prior-7-day average of 20.6%, confirming a multi-day downtrend rather than the usual saw-tooth bounce.

📈 Session Trends Analysis

Completion Patterns

The completion-rate line (blue) oscillates in a saw-tooth between ~40% recovery spikes (06-07, 06-10, 06-13) and 0–8% troughs, but the trailing week sits firmly in trough territory and ends at 0% today. The red action_required line stays high (44–50/day) throughout — daily completion% is dominated by the gate-firing-to-agent-session ratio, not agent quality.

Duration & Efficiency

Duration data is strictly bimodal: on productive days a handful of substantive sessions run 5–33 min, while gate-sweep days (06-09, 06-17, 06-20) collapse to zero timed sessions. With 0 successful sessions today, both the average and median duration are 0 — every one of the 50 runs was captured at gate-trigger time (created_at == updated_at).

Success Factors ✅ (from historical window — 0 successes today)

1. Agentic provenance on gate-sweep days: the only successes historically come from Running Copilot cloud agent and PR-comment workflows — never CI gate workflows (Q, Smoke CI, CGO, Agentic Commands). None fired successfully today.
2. Success-duration floor: historical successes cluster ≥~8–14 min; sub-minute sessions are gate sweeps, never completions.
3. Copilot-assigned PRs never orphan: all 8 active copilot/* PRs are Copilot-assigned → 0 orphaned branches.

Failure Signals ⚠️

1. Pure gate-sweep saturation: 49/50 action_required + 1 failure, all zero-duration — no agent work ran in the captured window, so completion% is structurally 0.
2. One real CI failure: .github/workflows/skillet.lock.yml failed on copilot/update-custom-css-themes — the same branch dominating today's gate load (see experimental section).
3. Sustained downtrend: recent-7d 6.0% vs prior-7d 20.6% — oscillation decaying toward the floor rather than recovering.

Prompt-quality analysis could not be computed: conversation transcripts unavailable (27th+ day, OAuth) — the longest-standing pipeline gap.

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 10 open PRs (0%)
• Historical Baseline: ~40% orphaned rate
• Status: ✅ NORMAL (well below the 50% elevated-waste threshold; ~28th consecutive healthy day)

Escalation Candidate Details

✅ No orphaned branches exceed the escalation threshold today.

• Only 2 in-progress runs repo-wide, both on main (housekeeping) → 0 gate firings on any PR branch.
• All 8 active copilot/* PRs (Add top-level goal frontmatter support and map it to Codex --goal #40442, Fix: fall back to default branch when workflow_dispatch trigger missing on PR branch #40441, fix: add --report-file flag to gh-aw logs to avoid shell redirect failure #40425, Add replace-label safe-outputs type #40423, Refresh docs site theme toward neutral GitHub-style surfaces #40422, model-inventory: alias updates 2026-06-20 #40420, fix(sdk-driver): resolve idle-timeout as success when output collected and all tools complete #40419, feat: add top-level auto_upgrade to generate a weekly agentic-auto-upgrade workflow #40414) are Copilot-assigned.
• 2 unassigned PRs (signed/jsweep [jsweep] Clean write_daily_aic_usage_cache.cjs #40433, fix/call-workflow fix: derive call-workflow job permissions from caller, not worker (#40169) #40175) have 0 gate firings and are idle housekeeping — not escalation candidates.

CI Waste Estimate

• Orphaned gate-hours today: 0 (no PR-branch gates without an assigned agent).
• The day's gate load is fully attributable to Copilot-assigned branches awaiting agent action, not to abandoned branches burning CI.

Notable Observations

Branch Concentration, Gate Workflows, and Diagnostics

Branch Concentration

Branch	Sessions	Share
copilot/update-custom-css-themes	27	54%
copilot/add-auto-updates-field	9	18%
copilot/add-goal-support-top-level	8	16%
copilot/investigate-fix-skillet-compiler-issue	6	12%

Gate Workflow Firings (today)

• Q: 15, Agentic Commands: 15, Smoke CI: 5, CGO: 3, Doc Build - Deploy: 3, AI Moderator: 2, CJS: 2, CWI: 2, Content Moderation: 2, skillet.lock.yml: 1 (the failure)

Loop / Context / Tool Diagnostics

• Loops: not detectable — 0 substantive sessions and no transcripts.
• Context issues: not assessable without transcripts.
• Tool usage: not observable from metadata.

Experimental Analysis

This run included experimental strategy: Gate Footprint Signature Classification

The strategy classifies each branch's gate activity by its refire ratio = total runs ÷ distinct workflows, distinguishing a broad one-pass CI fan-out from a single branch re-firing the same few workflows.

Branch	Runs	Distinct workflows	Refire ratio	Signature
copilot/update-custom-css-themes	27	5	5.4	🔁 Narrow high-refire (Q×12, Agentic Commands×12)
copilot/add-auto-updates-field	9	7	1.3	Broad single-pass
copilot/add-goal-support-top-level	8	8	1.0	Broad single-pass
copilot/investigate-fix-skillet-compiler-issue	6	6	1.0	Broad single-pass

Findings:

• The day's "50 gate sweeps" is not 50 distinct gates — it is heavily inflated by one branch (update-custom-css-themes) re-firing just two workflows (Q and Agentic Commands) 12× each.
• That same high-refire branch holds the day's only failure (skillet.lock.yml), hinting that repeated re-fires correlate with instability rather than healthy CI breadth.
• The Gate-Sweep Intensity Index (sessions ÷ branches = 12.5) masks this bimodality; the refire ratio surfaces it cleanly.

Effectiveness: Medium-High
Recommendation: Refine — track per-branch refire ratio over time and test whether high-refire branches predict failures/instability.

Actionable Recommendations

For Users Writing Task Descriptions

1. Cannot tailor prompt guidance this run — transcripts unavailable. General guidance stands: include explicit file paths and expected outcomes; tasks with concrete acceptance criteria historically complete far more often.

For System Improvements

1. Restore conversation-transcript fetching (OAuth) — Potential impact: High. This is the 27th+ consecutive day without transcripts; behavioral analysis (loops, context confusion, prompt quality) has been blind for nearly a month.
2. Investigate the Q + Agentic Commands re-fire loop on dominant branches — Potential impact: Medium. A single branch re-firing two workflows 12× each (and co-locating the only failure) suggests a retrigger/loop worth inspecting.

For Tool Development

1. Per-branch refire-ratio metric in the gate dashboard — Frequency of need: every gate-sweep day. Use case: distinguish genuine broad CI fan-out from a stuck/looping workflow pair without reading individual runs.

Statistical Summary

Sessions: 50 | Success: 0 (0%) | Failure: 1 (skillet.lock) | action_required: 49 | Zero-duration: 50
Avg/Median duration: 0.0/0.0 min | Burst: 05:58–06:22Z (24 min)
Branches: 4 (all copilot/*) | Dominant: update-custom-css-themes 54% (27)
GSII: 12.5 | Max refire ratio: 5.4 (Q×12 + Agentic Commands×12)
Orphans: 0/10 PRs (0% vs 40% baseline) | Escalations: 0
Completion: recent-7d 6.0% vs prior-7d 20.6% (downtrend)
Conversation logs: UNAVAILABLE (27th+ day, OAuth)

Next Steps

• Prioritize restoring conversation-transcript fetching (OAuth) — longest-standing pipeline gap
• Inspect the Q + Agentic Commands re-fire loop on copilot/update-custom-css-themes and its skillet.lock.yml failure
• Watch whether the 7-day completion downtrend (20.6%→6.0%) continues or reverts to a recovery spike
• Add per-branch refire-ratio tracking to validate the experimental strategy
