🤖 Copilot Agent Session Analysis — 2026-07-19

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-07-19 (07:04–07:44Z window)

• Average Duration: 1.18 min (completed sessions); successes averaged 2.6 min
• Conversation Logs: 4 recovered (2nd consecutive non-empty day after a 40+ day gap)
• Experimental Strategy: None — standard analysis (roll=77)

📈 Session Trends Analysis

Completion Patterns

Completion rebounded from 8% to 16% today, staying within the 4–18% floor band but recovering half the drop from the 07-16 spike. The success line tracks agentic runs only; the large failed/gated line reflects the persistent CI-gate sweep volume rather than true agent failures.

Duration & Efficiency

Average duration stays near ~1 min because zero-duration CI gate stubs dominate the population, pulling the median to 0. Loop count remains flat at 0 across the window — the recovered conversation logs confirm clean, non-looping execution (turns 13–21, 0/73 tool failures).

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	8 (16%)	↑ (from 8%)
Failed	1 (2%)	→
Action Required (CI gate sweeps)	20 (40%)	↓
In-Progress	21 (42%)	↑
Loop Detection Rate	0 (0%)	→
Tool Failures (in conv-logs)	0 / 73 calls	→
Orphaned Branches	0 / 15 (0%)	→

Success Factors ✅

1. Agentic provenance still owns every success: All 8 completions are agentic runs — Agentic Commands ×4 and Copilot Code Review ×4 — none are core CI gates. The provenance_inversion pattern holds for another day: agents finish work, gates just sweep.
2. Focused eslint work converts: 6 of 8 successes land on two eslint branches (eslint-factory-fix-logging-issue, fix-eslint-autofix-issue). Narrow, well-scoped lint fixes complete cleanly in 1.6–3.7 min.
3. Clean tool execution: Across the 4 conversation transcripts, 0 of 73 tool calls failed and no loops were detected (turns 13–21). Agents plan, edit, validate (parallel_validation), and report progress without churn.

Failure Signals ⚠️

1. CI gate saturation caps the ceiling: 20 sessions (40%) end in action_required — 15 of them "Agentic Commands" gate stubs at 0 duration. This is permission/gating friction, not agent failure, and it structurally holds completion in the low-double-digits.
2. High in-progress carryover: 21 sessions (42%) were still running at snapshot time — an unusually large tail (cloud-agent + comment-addressing runs consuming 537k–991k input tokens each via cache reads). These may resolve to successes post-window.
3. Single hard failure: 1 failure (workflow "CGO", 13.2 min) — the only genuine execution failure today.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Conversation logs show large, well-structured system/user prompts (8.4k–10.4k chars) with a skill-pr-finisher skill injection driving the comment-addressing runs. High-token, skill-scaffolded prompts correlate with clean, loop-free execution.

• Skill-scaffolded prompts (source=skill-pr-finisher): present in 2 of 4 transcripts, both progressing without loops.
• Narrow-scope branch names (fix-eslint-autofix-issue, eslint-factory-fix-logging-issue): 6/8 successes — specific, bounded tasks convert best.

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 15 open PRs (0%)
• Historical Baseline: ~40% orphaned rate
• Status: NORMAL ✅ (well below the 50% elevated threshold; ~53rd consecutive healthy day)

Escalation Candidate Details

✅ No orphaned branches exceed the escalation threshold today.

• All 15 open PRs have the Copilot agent assigned.
• Max simultaneous gates on any single branch: 3 (on main); every copilot/* branch had ≤1 in-progress run.
• CI waste from orphans: 0 gate-hours — no recoverable capacity is being lost to orphaned branches.

Notable Observations

Loop Detection, Tools, and Model Usage

Loop Detection

• Sessions with loops: 0. Turn counts 13–21 across the 4 transcripts, all forward-progressing.

Tool Usage

• Tools observed: bash, read_bash, view, edit, glob, parallel_validation, report_progress, search_code_subagent, skill, plus runtime-tools-secret_scanning and engine-tools-reply_to_comment.
• Tool success rate: 100% (73/73 successful).

Model Usage — ⚠️ Model Monoculture

• 100% of turns ran on claude-sonnet-4.6 across all 4 transcripts. This contrasts with 07-18's diversity (sonnet-4.6 ×3 + gpt-5.3-codex ×1). Worth watching whether the routing collapsed to a single model or the codex-backed runs simply weren't sampled today.
• Very high input-token load (537k–991k per run) driven by prompt-cache reads, against modest output (2.5k–4.9k) — efficient generation, heavy context.

Experimental Analysis

Standard analysis only — no experimental strategy this run.

Actionable Recommendations

For Users Writing Task Descriptions

1. Keep task scope narrow and branch names descriptive — the eslint fixes that named their exact target completed in under 4 minutes with zero loops. Prefer fix-eslint-autofix-issue over just fix the lint.
2. Lean on the pr-finisher skill scaffold — skill-injected prompts drove clean, loop-free comment-addressing runs.

For System Improvements

1. Investigate the model monoculture (impact: Medium) — confirm whether 100% sonnet-4.6 is intended routing or a lost codex-backed lane vs. 07-18.
2. Reduce CI-gate action_required noise (impact: High) — 40% of sessions are 0-duration gate stubs that depress the headline completion rate without reflecting agent quality. Separating gate sweeps from agentic runs in reporting would surface the true ~80%+ agentic success rate.

For Tool Development

• No missing tools were requested in the transcripts; tool coverage appears sufficient.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate: 8% → 16% day-over-day; oscillating within the 4–18% floor regime (30d-mean ~13%), with occasional saw-tooth spikes (54% on 07-04, 38% on 07-16).
• Conversation logs: recovered for a 2nd consecutive day — the fetch pipeline appears healthy again after 40+ empty days.
• Orphan health: 0% for ~53 consecutive days; the ~40% baseline is never approached in this repo because Copilot assignment is universal.

Next Steps

• Confirm whether the 100% sonnet-4.6 monoculture is intended routing
• Consider reporting agentic-run success separately from CI-gate sweeps
• Schedule follow-up analysis tomorrow (daily cadence)
