🤖 Copilot Agent Session Analysis — 2026-08-27

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-08-27, 07:06–07:29 UTC (23-minute fetch window)
• Completion Rate: 32.0%
• Average Duration: 2.82 min (median 0.0 min)
• Experimental Strategy: None — standard run (roll=52, threshold 30)

Data-quality note up front: conversation transcript logs ({run_id}-conversation.txt) are empty for the 6th consecutive recorded snapshot (49+ days historically, per repo memory). Zero of the 50 sessions produced a turn-by-turn log, so all metrics below are derived from workflow-run metadata only (name, branch, conclusion, timestamps) — not from actual agent reasoning, tool calls, or token usage. Loop detection, tool-usage patterns, and context-confusion detection are therefore not measurable this run.

Key Metrics

Metric	Value	Trend (vs 08-26)
Total Sessions	50	→
Successful Completions	16 (32.0%)	→
Failed/Blocked (action_required + failure)	34 (68.0%)	→
Average Duration	2.82 min	→ (+0.02 min)
Loop Detection Rate	N/A — no conversation logs	→
Context Issues	N/A — no conversation logs	→

Success Factors ✅

1. "Addressing comment on PR #N" follow-up tasks: 4/4 succeeded (100%) — Allow strict-mode workflows to pass AWF --image-tag while keeping sandbox.agent.args locked down #56265 (7.75 min), E007: ignore inert code-region mentions in comment limit enforcement #56269 (6.47 min), Resolve dispatch workflow refs from PR comments #56266 (14.02 min), Include grader evaluator scripts in workflow packages #56268 (23.63 min). These are the only sessions in today's batch that represent an agent actually doing follow-up coding work in response to specific PR feedback, and they cleared 100%.

   • Example: a scoped, single-PR-comment task with a known target branch and clear acceptance criterion (resolve the reviewer's comment).

2. Single-branch PR-open gate bundles pass cleanly when unblocked: branch copilot/gh-aw-env-update-fix cleared 11/16 (69%) of its review/CI gate bundle (CWI, CGO, code-quality/skills reviewers, Test Quality Sentinel, PR Data Prefetch, Agentic Commands ×2) in a tight ~9-minute window (07:08–07:17), evidence the automated review fan-out itself is fast and largely reliable once triggered.

3. Zero orphaned branches, 6th consecutive healthy day: no PR branch is starved of agent attention — every gate-heavy branch either has a Copilot assignee or has zero simultaneous gate firings.

Failure Signals ⚠️

1. Provenance inversion (6th+ consecutive observation): only 4 of 16 successes (25%) are true agentic task completions; the remaining 12 (75%) are CI-gate/review-bot workflows executing green. The daily "32% completion rate" headline number is mostly a measure of how many automated gates fired and passed, not of agent task success.

   • Failure rate proxy: excluding the CI-gate/review-bot successes, true agentic completion is 4/4 (100%) but only 4 agentic sessions ran all day — a very small, likely unrepresentative sample.

2. Single-branch concentration dilutes the daily rate: copilot/gh-aw-env-update-fix alone accounts for 32% of all 50 sessions (16/50). Excluding that branch, completion falls to 14.7% (5/34) — much closer to the historical floor (2–10%) than the reported 32% headline suggests.

   • Example: a repo with 8 active copilot/* branches today, but review/CI gate volume on one branch is enough to swing the aggregate completion rate by ~17 points.

3. Isolated review-gate failure: Design Decision Gate 🏗️ failed (15.6 min) on copilot/gh-aw-env-update-fix, the only failure in the whole 50-session batch, while every other gate on that same branch passed — worth a manual look at what that gate flagged, since it's the one dissenting signal on an otherwise fully-green branch.

4. Conversation log fetch failure, ongoing: this is now a standing infrastructure defect (49+ days) that blocks every behavioral analysis strategy this workflow is designed to run (loop detection, tool-usage patterns, context-confusion detection, prompt-quality scoring below). It should be treated as a bug to fix, not a recurring caveat to restate.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

No prompt text is available in workflow-run metadata — only workflow/task names, not the underlying task descriptions the agent received. What can be said from task-type alone:

Higher-reliability task-type signal

• "Addressing comment on PR #N" tasks: 4/4 succeeded today, and this task type has shown high reliability across every prior recorded snapshot back to 2026-03-31 ("Addressing comment on PR" tasks remain high-reliability, 100% in multiple past days). These tasks come with an inherently scoped, well-defined unit of work (one reviewer comment, one branch).

Lower-reliability / harder-to-interpret task types

• Multi-gate review-bot fan-outs (Skills Reviewers, Design Decision Gate, Test Quality Sentinel, etc.) are not user-authored prompts at all — they are triggered automatically per PR-open and their "success/failure" reflects gate logic, not prompt quality. Bundling them into the completion-rate denominator is a known source of aggregate-rate noise (see Failure Signal rejig docs #1).

We cannot produce example high/low-quality prompt text this run — doing so requires the actual task description sent to the agent, which lives in the missing conversation logs, not in workflow-run metadata.

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 13 open PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (30-day-style mean over 5 recorded days: 08-22 through 08-26, all 0.0%)
• Status: NORMAL (0.0% today vs 0.0% baseline — well under the +20pt elevation threshold)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. All 3 in-progress workflow runs in the last 6 hours are on main (0 gates on any PR branch); all 13 open PRs are either Copilot-assigned or carry zero simultaneous gate firings.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no escalation candidates, so no orphaned CI-minutes to estimate.
• Recoverable capacity: N/A this run.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Sessions with loops: N/A — not measurable without conversation logs (assume 0 for trend-continuity purposes, consistent with every prior recorded snapshot).
• Average loop count: N/A
• Common loop patterns: N/A — this analysis strategy requires turn-by-turn transcript data, which was not available for any of the 50 sessions.

Tool Usage

• Most used tools: N/A — no tool.execution_start/tool.execution_complete log lines were available in any session.
• Tool success rates: N/A
• Missing tools: N/A — cannot be assessed without conversation logs.

Context Issues

• Sessions with confusion: N/A — not measurable this run.
• Common confusion points: N/A
• Clarification requests: N/A

What we could measure (metadata only)

• Duration distribution: 17/50 sessions had non-zero duration (the rest are 0-duration gate stubs recorded at a single timestamp); of those 17, mean 8.29 min, median 7.43 min, max 23.63 min (Addressing comment on PR #56268), min 0.63 min (PR Data Prefetch, 38s).
• Branch concentration: 8 unique copilot/* branches; top branch (copilot/gh-aw-env-update-fix) = 32% of sessions; top-2 (copilot/gh-aw-env-update-fix + copilot/fix-gh-aw-add-omit-evaluator-files) = 46%.

Experimental Analysis

This run included experimental strategy: None

Standard analysis only this run (roll=52, experimental threshold is <30). No novel strategy was tested; today's insights come entirely from the standard six analysis strategies applied to workflow-run metadata.

Actionable Recommendations

For Users Writing Task Descriptions

1. Prefer scoped, comment-anchored follow-ups over open-ended asks: "Addressing comment on PR #N" tasks hit 100% today and have been consistently high-reliability across the full recorded history. When possible, phrase a task as "resolve this specific reviewer comment on PR #N" rather than a broader, multi-file request.

   • Example: Before: "clean up the PR based on feedback." After: "address the comment on PR Include grader evaluator scripts in workflow packages #56268 about X — update file Y accordingly."

2. Don't read the daily completion-rate headline in isolation: today's 32% is driven 75% by CI-gate/review-bot green runs on one branch, not by agent task success. When triaging, look at the branch-excluded completion rate (14.7% today) as the more representative agentic-quality signal.

For System Improvements

1. Fix the conversation-log fetch pipeline: 49+ consecutive days of empty transcript logs is no longer a caveat — it's a standing defect that prevents this workflow from ever delivering on its core stated mission (loop detection, tool-usage patterns, context-confusion detection, prompt-quality scoring). Potential impact: High — every "Notable Observations" and "Prompt Quality" section in every daily report has been degraded to metadata-only for 7+ weeks.

2. Separate CI-gate/review-bot runs from agentic task runs in the completion-rate calculation: report a "true agentic completion rate" alongside the raw completion rate, so the headline number isn't dominated by gate-bundle green-sweeps on whichever branch happens to be most active that day.

For Tool Development

1. Conversation/transcript log extraction from GitHub Actions job logs: this is the single missing capability blocking the entire behavioral-analysis half of this workflow's brief. Frequency of need: every one of the last 49+ recorded runs. Use case: turn-by-turn model/token/tool-call analysis as described in the workflow's own Phase 1 instructions.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: 32% (08-22) → 42% (08-23) → 26% (08-24) → 10% (08-25) → 32% (08-26) → 32% (08-27). Persistent saw-tooth, no regime change; 6-day mean 29.0%.
• Average duration trend: 2.64 → 2.76 → 2.15 → 0.82 → 2.80 → 2.82 min. Tracks completion rate loosely (both dipped on 08-25).
• Quality improvement: Not assessable — prompt-quality scoring requires conversation logs, unavailable for 6+ consecutive snapshots (49+ days historically).

📈 Session Trends Analysis

Completion Patterns

Completion rate has oscillated in a 10–42% band over the last six recorded days with no sustained upward or downward trend (6-day mean 29.0%). The 08-25 trough (10%) was the sharpest single-day pullback in the window; today's 32% matches both 08-22 and 08-26, each time driven by one heavily-gated branch rather than a broad improvement in agent success.

Duration & Efficiency

Average duration has stayed in a narrow 0.8–2.8 min band, dipping alongside completion rate on 08-25 and recovering since. Median duration is flat at 0 minutes on every single day in this window — a direct artifact of ~33 zero-duration CI-gate stubs being recorded per day, and a reminder that duration and loop metrics here reflect workflow-run metadata, not actual agent working time.

Next Steps

• Review recommendations with team, especially the standing conversation-log fetch defect (49+ days)
• Consider separating "true agentic completion rate" from raw completion rate in the daily headline
• Manually review the Design Decision Gate 🏗️ failure on copilot/gh-aw-env-update-fix
• Schedule follow-up analysis tomorrow (2026-08-28)
