🤖 Copilot Agent Session Analysis — 2026-06-13

Executive Summary

• Sessions Analyzed: 50 (5 Copilot branches)
• Analysis Period: 2026-06-13 04:36–05:32 UTC (~56-minute CI burst snapshot)
• Completion Rate: 38% — a recovery day, the 4th-highest in the 12-day window and well above the 7-day average (~20.6%)
• Average Duration: 4.65 min overall (11.6 min across the 20 non-trivial sessions)
• Experimental Strategy: None this run (standard analysis; experimental roll 96 ≥ 30)
• Orphaned Branches: 0 escalation candidates ✅

⚠️ Data note: Agent conversation transcripts were again unavailable (empty logs/ directory — ~21st+ consecutive day, persistent OAuth gap). This analysis is metadata-only and infers behaviour from workflow-run conclusions, durations, and branch topology rather than the agent's internal monologue.

📈 Session Trends Analysis

Completion Patterns

Completion oscillates in a bimodal regime — recovery days (38–46%) alternate with near-zero floor days. Today's 38% (green/blue lines climbing) is the latest recovery, rebounding sharply from the 06-12 floor of 4% and sitting well above the ~20.6% 7-day average.

Duration & Efficiency

Average duration tracks recovery days closely: today's 4.65-min mean reflects long review-workflow runs, while the all-session median stays at 0 because gate-snapshot sweeps dominate the count. No loop/retry sessions were detected across the window (purple bars appear only on 05-23).

Success Factors ✅

1. Review/gate/moderator workflows produced the successes (Provenance Inversion confirmed): All but two of the 19 successes came from gate and review workflows — PR Code Quality Reviewer (30.2 min), Matt Pocock Skills Reviewer (27.9 min), Design Decision Gate (21 min), Test Quality Sentinel (20.4 min), CGO, CWI, Agentic Commands, Running Copilot Code Review, Doc Build, Smoke CI. This inverts the pure-gate-sweep-day pattern (where only the cloud-agent workflow succeeds) and matches the 06-07 "provenance inversion" regime.
2. Productive-branch concentration: copilot/lint-monster-refactor-functions (8/13 success, 62%) and copilot/lint-monster-fix-context-propagation-issues (5/7, 71%) carried productivity, hosting every long-running success.
3. Direct PR-comment tasks remain reliable: Both "Addressing comment on PR" runs (Resolve context propagation and environment-mutation lint findings in CLI/workflow paths #39007, fix: correct malformed CreateArtifact Twirp request, make upload_artifact failures non-fatal, and add live API integration tests #39008) succeeded (13.3 / 16.2 min) — consistent with the long-standing high-reliability of this task type.
4. Success-duration floor holds: Every one of the 19 successes had a non-zero duration; the six longest (17–30 min) all landed on the refactor branch — substantive work, not gate firings.

Failure Signals ⚠️

1. Gate-sweep branches stay inconclusive: copilot/aw-failures-fix-upload-artifact-request logged 1/13 success (8%) — 12 action-required gate firings awaiting agent/approval action rather than green CI. Per the established Inverse Gate-Count to Conclusiveness strategy, a high per-branch gate count correlates with waiting-on-action, not productivity.
2. Bimodal duration split: 30 of 50 sessions completed in ~0 min (gate snapshots) versus 20 substantive sessions (0.5–30.2 min). The all-session median is therefore 0, while the non-trivial mean is 11.6 min.
3. Narrow sampling window: The 50 runs span only ~56 minutes — a CI burst snapshot, not a full-day execution sample, so absolute counts should be read as a point-in-time slice.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Conversation transcripts remain unavailable, so prompt quality is inferred from task type and outcome rather than the agent's reasoning text.

• Higher-reliability: scoped refactor branches (lint-monster-*, 13/20 combined) and direct PR-comment addressing (Resolve context propagation and environment-mutation lint findings in CLI/workflow paths #39007, fix: correct malformed CreateArtifact Twirp request, make upload_artifact failures non-fatal, and add live API integration tests #39008, 2/2) — bounded targets and explicit context convert reliably.
• Lower-reliability: broad failure-fix branches (aw-failures-fix-upload-artifact-request, 1/13) — wide scope, mostly gate firings awaiting action.

Behavioural prompt-quality scoring is blocked until conversation logs are restored (OAuth re-auth needed).

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 4 open PRs (0%)
• Historical Baseline: ~40% orphaned rate
• Status: ✅ NORMAL (well below the 50% elevated-waste threshold)

Escalation Candidate Details

✅ No orphaned branches exceed the escalation threshold today.

All 4 open PRs inspected: #39008, #38965, #38911 are Copilot-assigned; #39019 (jsweep) is unassigned but has 0 active gates. Both in-progress runs at snapshot time were on main, so no PR branch had an active gate sweep — no PR meets the ≥5-gate orphan criterion. Orphan rate is at the floor for a 7th consecutive observed day.

Notable Observations

Loop Detection, Tool/Workflow Usage, and Diagnostics

Loop Detection

• Sessions with loops: 0 (0%). No duration or retry signatures indicating circular behaviour; the longest run (30.2 min, PR Code Quality Reviewer) completed cleanly.

Workflow Usage

• Most active: Q (8), Agentic Commands (8), Smoke CI / CWI / CGO (4 each).
• Pure gate, 0 success: Q (0/8), Label Closed PRs (0/3), PR Description Updater (0/3), CJS (0/2) — action-required by design.

Branch Topology

Branch	Gates	Success	Share
copilot/fix-runs-on-slim-label-selection	15	5	30%
copilot/lint-monster-refactor-functions	13	8	26%
copilot/aw-failures-fix-upload-artifact-request	13	1	26%
copilot/lint-monster-fix-context-propagation-issues	7	5	14%
copilot/deep-report-add-githubmcpmode-enum	2	0	4%

Top-branch share 30%, top-3 share 82% — moderate concentration.

Context / Conversation Logs

• Sessions with detectable confusion: not assessable (no transcripts).
• Conversation logs: unavailable for the 21st+ consecutive day (OAuth gap) — the single most persistent data-quality gap in this analysis series.

Experimental Analysis

Standard analysis only — no experimental strategy this run (experimental roll 96, threshold <30).

Actionable Recommendations

For Users Writing Task Descriptions

1. Prefer scoped, single-concern branches: the two lint-monster-* branches (62–71% success) outperformed the broad aw-failures-fix-* branch (8%). Name the file and the invariant to preserve rather than "fix the failures."
2. Anchor work to a specific PR thread when possible: direct "Addressing comment on PR" tasks succeeded 2/2.

For System Improvements

1. Restore conversation-log ingestion (high impact): 21+ consecutive days without transcripts blocks all behavioural analysis (reasoning quality, loop detection, error recovery). Re-authenticating the log-fetch OAuth flow is the highest-leverage fix.
2. Distinguish gate firings from agent sessions in the completion denominator (medium impact): Because ~60% of "sessions" are zero-duration gate snapshots, the headline completion rate tracks the gate-to-agent ratio more than agent quality. A separate "agent-session completion rate" would be more informative.

For Tool Development

1. Per-branch gate-vs-agent dashboard: Surfacing real-time gate count per branch (need observed: 5 branches) would let maintainers spot waiting-on-action branches before they accumulate sweeps.

Historical Trends and Statistical Summary

Trends Over Time

7-day completion sequence (06-07 → 06-13): 40% → 4% → 0% → 40% → 18% → 4% → 38%.

• Completion rate: oscillating bimodal regime — recovery days (38–40%) alternate with floor days (0–4%). Today is a recovery day; 7-day average ≈ 20.6%.
• Duration: avg rebounded to 4.65 min from 1.13 min on 06-12, driven by long review-workflow runs on the refactor branch.
• Orphans: held at 0 for a 7th consecutive observed day.

Statistical Summary

Sessions: 50 | Success 19 (38%) | Action-required 30 (60%) | Skipped 1 | Failures 0
Duration: avg 4.65m | median 0.00m | non-trivial mean 11.62m | max 30.20m | min non-zero 0.50m
Loops: 0 | Orphan candidates: 0 | Branches: 5 | Top share 30% | Top-3 82%
Conversation logs: unavailable (OAuth, 21st+ day) | Data quality: metadata-only

Next Steps

• Restore conversation-log OAuth — unblock behavioural analysis (longest-standing gap)
• Review whether the headline completion metric should separate gate firings from agent sessions
• Continue monitoring the recovery/floor oscillation; schedule follow-up analysis tomorrow
