🤖 Copilot Agent Session Analysis — 2026-06-04

Executive Summary

• Sessions Analyzed: 50 (window 06:05–06:22 UTC)
• Completion Rate: 8% (4/50) — modest rebound from yesterday's 4%, below the 7-day avg of 17.7%
• Average Duration: 1.01 min (median 0.0 — strongly bimodal)
• Experimental Strategy: Approval-Gated Branch Bifurcation Index

Headline: The cleanest demonstration in the window of outcome bifurcation by branch approval state. Of 5 active branches, exactly one — copilot/update-install-copilot-cli-script — was past first-party approval and produced 100% of substantive work: all 4 successes, both failures, all 7 sessions in the 5–9 min band. The other 4 branches were 100% action_required gate sweeps, every session under 1 minute.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	4 (8%)	↑ (from 4%)
Failed / Skipped	2 (4%) / 1 (2%)	↑
action_required (gating)	43 (86%)	↓ (from 96%)
Average Duration	1.01 min	↑
Substantive sessions (≥5 min)	7 (14%)	↑
Unique branches / top share	5 / 24%	↑ / ↓
Orphaned-branch escalations	0	→

Success Factors ✅

1. Single approved branch carries all real work: update-install-copilot-cli-script (PR Compat-based Copilot CLI install: single remote fetch, jq-only resolution, TTL-aware cache, and gh-aw-actions-sourced release policy #36676) = 4/4 successes + 2/2 failures — a 44% success rate (4/9) on the only branch past first-party approval.
2. Substantive-duration floor holds: every success ran 5.78–8.70 min; every productive session fell in the 5–9 min band. No sub-minute session produced useful work.
3. Workflow type doesn't gate success: approved-branch successes spanned Agentic Commands, Smoke CI, Doc Build – Deploy, PR-comment addressing — approval, not workflow type, is the variable.

Failure Signals ⚠️

1. Pre-approval gate sweeps dominate (86%): 41/50 sessions across 4 branches (ab-advisor-experiment-max-turns, ambient-context-optimizer-2026-06-04, debug-workflow-failure, fix-tolowerequalfold-issue) were 100% action_required, all <1 min — awaiting approval, not failing on capability.
2. Low concentration did not help: most dispersed branch set in the window (top only 24%), yet outcome stayed gate-dominated — because 4 of 5 branches were pre-approval. Dispersion is irrelevant when approval is the bottleneck.
3. Two genuine failures on the approved branch (CJS 7.63 min, CGO 9.00 min) — the only non-gating failures, worth triaging as real agent/CI breakage.

Prompt Quality Analysis 📝

Conversation transcripts remain unavailable — the single fetched log contained only an OAuth re-auth error. This is the 12th+ consecutive day without internal-monologue data, so quality is inferred from metadata: branches past first-party approval correlate with substantive runs (5–9 min, 44% success); sub-minute runs on pre-approval branches yield 100% action_required and no work.

Orphaned Branch Escalation Alerts 🚨

Branches with ≥5 simultaneous gate firings and no Copilot agent for >2 hours.

• Orphaned Branches Today: 0 of 13 open PRs (0%)
• Historical Baseline: ~40% — Status: ✅ NORMAL (well below the 50% elevated threshold)

Escalation Candidate Details

✅ No orphaned branches exceed the escalation threshold. At detection time only 2 in-progress runs existed repo-wide — both the analysis workflow itself on main. No PR branch had an active gate sweep; the morning sweeps had already completed.

Category	Count	Notes
Open PRs	13	5 Copilot-assigned, 8 unassigned
Unassigned PRs	8	All dependabot/* — 0 gate firings (idle, not orphaned)
Active gate sweeps on PR branches	0	—

CI waste: 0 recoverable orphaned gate-hours. The 4 pre-approval agent branches are Copilot-assigned and awaiting human approval — approval latency, not orphaning.

Notable Observations

Diagnostics: duration & branch × outcome

Bimodal duration: 43 sessions <1 min (sweeps) + 7 @ 5.78–9.00 min (real work). Median 0.0 vs mean 1.01. Longest 9.00 min (CGO, fail); shortest substantive 5.78 min (Agentic Commands, success).

Branch	Sessions	Outcome
update-install-copilot-cli-script (approved)	9	4 success / 2 failure / 2 action_required / 1 skipped
fix-tolowerequalfold-issue	12	12 action_required
debug-workflow-failure	10	10 action_required
ambient-context-optimizer-2026-06-04	10	10 action_required
ab-advisor-experiment-max-turns	9	9 action_required

Gaps: conversation logs missing (OAuth, 12th+ day); Python libs not pre-installed (installed via pip for charts).

📈 Session Trends Analysis

Completion Patterns

Completion ticked 4% → 8% but stays in the low band dominant since 06-01, far off the ~45% peaks of 05-23/05-26. The high non-success line reflects action_required gating, not agent failure.

Duration & Efficiency

Average duration (1.01 min) sits below the ~5-min substantive floor — a gate-sweep day. The bimodal split (43 sweeps + 7 real) is the truer picture; all 7 real sessions live on the single approved branch.

Experimental Analysis

Approval-Gated Branch Bifurcation Index (experimental run — random draw 11 < 30)

Hypothesis: daily completion is essentially a function of how many sessions land on approved branches, independent of burst structure or concentration. Today was a near-perfect natural experiment.

Findings:

• Branches bifurcate cleanly — 1 approved (100% of substantive work) vs 4 pre-approval (100% gate sweeps), zero overlap.
• The approved branch was only 9/50 (18%) of sessions, capping the achievable rate near ~18%; observed 8% is lower because that branch was itself 44% successful.
• Concentration was irrelevant: despite the most dispersed branch set in the window, the gate-sweep majority held.

Effectiveness: High — cleanly explains today and generalizes burst_outcome_branch_dependence. Recommendation: Keep — track "approved-branch session share" as a completion-ceiling indicator.

Actionable Recommendations

For maintainers: (1) Approve agent branches faster — the dominant loss is approval latency, not capability; 41/50 sessions burned awaiting approval. (2) Triage the 2 substantive failures (CJS, CGO) as real signals distinct from gating noise.

For the system: (1) Surface "approved-branch session share" as a dashboard metric — High impact, predicts the daily ceiling. (2) Suppress/batch pre-approval gate sweeps — Medium — 41 sub-minute runs add noise without work.

For tooling: Fix the conversation-log OAuth fetch (12+ consecutive days) — until resolved, every report is metadata-only.

Statistical Summary

Total Sessions:              50
Successful:                  4 (8%)
Failed / Skipped:            2 (4%) / 1 (2%)
action_required (gating):    43 (86%)

Avg Duration:                1.01 min
Median Duration:             0.00 min
Longest:                     9.00 min (CGO, failure)
Shortest substantive:        5.78 min (Agentic Commands, success)

Substantive (>=5m):          7 (14%) — all on the approved branch
Unique branches:             5 (top share 24%)
Approved branches:           1 (100% of substantive work)
Pre-approval sweep branches: 4 (100% action_required, all <1 min)

Orphaned escalations:        0
Conversation logs:           0 (OAuth error, 12th+ consecutive day)

Trend: completion oscillating in a low band (7-day avg 17.7%); orphan rate 0% vs ~40% baseline (agent assignment healthy).

Next Steps

• Prioritize first-party approval for the 4 pending agent branches
• Triage the 2 substantive failures (CJS, CGO) on update-install-copilot-cli-script
• Resolve the conversation-log OAuth fetch failure
• Track "approved-branch session share" as a leading completion indicator
