🤖 Copilot Agent Session Analysis — 2026-09-25

Executive Summary

• Sessions Analyzed: 50 (metadata-only — see data-quality note below)
• Analysis Window (today): 2026-09-25 06:02–06:52 UTC (~50 min)
• Trend Window: 33 recorded days (2026-08-22 → 2026-09-25, with some gaps)
• Completion Rate: 20.0% (10 success / 38 action_required / 2 in_progress), below the 32-day mean of 31.8% (range 4–78%), down from 44.0% on 09-24
• Average Duration (proxy): 1.44 min / Median: 0 min
• Experimental Strategy: none this run (roll=92, threshold <30 — standard analysis only)

Data-quality note: this window's 50 "sessions" are CI/gate check-runs and code-review bot runs on 3 active copilot/* branches (repeated pushes to open PRs), not 50 distinct Copilot agent task sessions. Conversation transcript logs were empty for the 33rd+ consecutive recorded day — turn-by-turn tool-use, token, and loop data remain unavailable. This is a standing, previously-flagged tooling gap, not new to this run. All metrics below are derived from run metadata (status/conclusion/timestamps/head_branch), consistent with this workflow's established methodology over the past month.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→
Successful Completions	10 (20.0%)	↓ vs 09-24 (44.0%)
Action Required (blocked gates)	38 (76.0%)	↑
In Progress (at snapshot)	2 (4.0%)	→
Average Duration (proxy)	1.44 min	↓
Orphan Rate	0.0% (0/18 open PRs)	→ (33rd healthy day)
True-agentic completions	2/2 (100%)	→ (5th consecutive full-recovery day)

Success Factors ✅

1. True-agentic task completions stayed perfect: both resolved "Addressing comment on PR" runs succeeded (PR Scope forked-repository checkout guard to PR replays #63011, PR Improve AWF download failure diagnostics #63318) — a 5th consecutive 100% day for this category (after 7/7 on 09-22, 5/5 on 09-23, 5/5 on 09-24), though on a small daily sample (n=2, +1 still in-progress).
2. Code-scanning bot sweeps fully green: all 8 "Code scanning AI findings" runs on PR Support dynamic checkout sets from GitHub Actions expressions #63241 succeeded (100%), each firing in the same push cycle as blocked CGO/CWI/CJS runs — confirms code-scanning and core CI gates are independent, not correlated failures.
3. Isolated (non-bursty) runs vastly outperform clustered ones: single-fire runs succeeded 66.7% (8/12) vs same-second burst-fired runs at 5.3% (2/38) — a 12.7x gap, the widest recorded (prior peak ~8x), reinforcing the standing burst_vs_isolated_success_gap pattern.
4. Orphan safety net holds: 0/18 open PRs met the escalation threshold; both branches generating the most gate traffic (copilot/dynamic-checkouts-github-action, copilot/add-diagnostic-message-for-failure) have Copilot actively assigned.

Failure Signals ⚠️

1. Branch-level stuck gate, no exceptions (standing pattern, now observed on most recorded days): CGO (10/10), CWI (10/10), CJS (10/10), and Doc Build - Deploy (8/8) all landed at action_required — 0% success across all 4 core CI-gate workflow types today, while every true-agentic/code-scanning run succeeded (100%) — the same perfectly bimodal split first recorded on 09-22.
2. Single-branch concentration hit a new high: copilot/dynamic-checkouts-github-action produced 44/50 (88%) of all sessions today, surpassing the prior record of 86% (09-22) — one branch's rapid push/gate cycle now dominates the entire 50-run sampling window, which caps how many other branches' activity this snapshot can capture.
3. Tight re-fire cadence on PR Support dynamic checkout sets from GitHub Actions expressions #63241: 9 push cycles in ~40 minutes (roughly every 5 min) each re-triggered CGO+CWI+CJS(+Doc Build-Deploy), every one blocked — consistent with the standing branch_level_stuck_gate pattern rather than a new regression, but the density is unusually high.
4. Completion rate below trend: 20.0% sits 11.8 points under the 32-day mean (31.8%), continuing the saw-tooth oscillation documented on prior days rather than a sustained decline.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

No prompt text or conversation transcripts are available this run (0 files in the logs directory, 33rd+ consecutive empty day). Prompt-quality analysis cannot be performed from CI/gate run metadata alone — the name field only exposes workflow/trigger labels (e.g. "Addressing comment on PR #63011"), not the underlying task description. This limitation has persisted since tracking began; see the Orphaned Branch section and Notable Observations for what is measurable from 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 18 open PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (mean over 32 recorded prior days)
• Status: NORMAL — 33rd consecutive healthy day

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. Only 2 in-progress workflow runs existed repo-wide in the trailing 6h, both on main (this analysis workflow + Tidy). The two active copilot/* branches generating gate traffic (copilot/dynamic-checkouts-github-action, PR #63241; copilot/add-diagnostic-message-for-failure, PR #63318) both have Copilot in their assignee list.

CI Waste Estimate

Not applicable — no branch crossed the gate-count/no-agent/wait-time thresholds, so there is no orphaned CI capacity to recover today.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Turn-level loop detection is unavailable (no conversation transcripts). At the metadata level, PR Support dynamic checkout sets from GitHub Actions expressions #63241 shows a repeated blocked-gate re-fire cycle (9 cycles in ~40 min) — see Failure Signals Add workflow: githubnext/agentics/weekly-research #3. This matches the long-running branch_level_stuck_gate pattern rather than a newly discovered loop behavior.

Tool Usage

• Not observable this run (no transcripts). Workflow/check-run usage: CGO, CWI, CJS, Doc Build - Deploy (10/10/10/8 firings, all action_required), Code scanning AI findings (8 success + 1 in_progress), Addressing comment on PR (2 success + 1 in_progress).

Context Issues

• Not measurable from metadata alone.

Experimental Analysis

Standard analysis only this run — no experimental strategy triggered (roll=92, threshold <30).

Actionable Recommendations

For Users Writing Task Descriptions

1. N/A this run: without conversation transcripts, prompt-text recommendations can't be derived from today's data. See the standing recommendation below re: restoring transcript capture.

For System Improvements

1. Investigate the perpetually-blocked core CI-gate bundle (CGO/CWI/CJS/Doc Build-Deploy): these four workflows have shown at or near 0% success on action_required-dominated branches across most recorded days, including a clean 0/38 today. If this reflects a structural approval-gate requirement (not a bug), consider whether "action_required" should be excluded from the raw completion-rate denominator to avoid misleadingly depressing the headline number — the 09-20 push_event_reattribution experiment found push-level completion is >2x the raw session-level rate.
   • Potential impact: High (directly affects how "completion rate" should be interpreted and reported).
2. Restore conversation transcript capture: 33rd+ consecutive day with 0 log files. This remains the single largest standing gap — it blocks all turn-by-turn behavioral, tool-usage, loop, and prompt-quality analysis this workflow is designed to produce.
   • Potential impact: High.

For Tool Development

1. No new tool gaps identified this run — the same missing capability (conversation-transcript ingestion) as prior days is the binding constraint, not a missing tool in this workflow itself.

Historical Trends and Statistical Summary

Trends Over Time

Completion rate has oscillated in a saw-tooth pattern for over a month (4–78% range, 31.8% mean); today's 20.0% is a below-mean dip following 09-24's above-mean 44.0%, not a new trend. The "not completed" series (gray) tracks action_required/pending/in-progress runs and consistently outnumbers successes — a persistent structural feature of this CI-gate-heavy sampling, not a recent regression.

Average duration (a metadata proxy: updated_at - created_at, not true agent working time) is highly volatile day-to-day, dominated by occasional merge/close-invalidation-cascade artifacts that inflate single days (e.g. the 09-20 and 09-23 spikes). Today's 1.44 min average and 0 min median are on the low end of the range, consistent with a window containing no PR merges or closes (no cascade inflation) and mostly fast, immediately-resolved gate check-runs.

Next Steps

• Review whether action_required should be excluded from the completion-rate denominator, per the 09-20 push-level-reattribution finding
• Continue tracking conversation-transcript availability as the top-priority tooling gap
• Monitor copilot/dynamic-checkouts-github-action's single-branch concentration (now a record 88%) in case it persists across multiple days
• Schedule follow-up analysis tomorrow (2026-09-26)
