🤖 Copilot Agent Session Analysis — 2026-08-22

Executive Summary

• Sessions Analyzed: 50 GitHub Actions workflow runs (metadata only — see data-quality note below)
• Analysis Period: 32.4-minute window, 2026-08-22 06:08–06:41 UTC
• Completion Rate: 32% — highest since 2026-07-04 (54%)
• Average Duration: 2.64 min (all runs) / 6.93 min (19 non-zero-duration runs)
• Experimental Strategy: Branch-Level Gate Bundle Concentration

⚠️ Data-quality note: logs/ contained 0 {run_id}-conversation.txt transcript files this run — the 45th+ consecutive recorded snapshot with no agent conversation data available (see [Active patterns] in repo memory). All metrics below come from workflow-run metadata (sessions-list.json: conclusion, timing, branch, workflow name) rather than turn-by-turn transcripts. Sections that require conversation logs (tool-usage patterns, loop detection, prompt-quality scoring) are marked N/A rather than estimated.

Key Metrics

Metric	Value	Trend
Total Sessions (workflow runs)	50	→
Successful Completions	16 (32%)	↑ from 8% (07-08)
Failed	2 (4%)	↑ from 0 (07-08)
Action-required / pending gates	31 (62%)	↓
Cancelled	1 (2%)	→
Average Duration	2.64 min	↑ from 1.59 min (07-08)
Orphaned Branches	0 / 20 open PRs (0%)	→ (43rd consecutive healthy day)
Loop Detection Rate	N/A (no conversation logs)	—

Success Factors ✅

1. Full gate-bundle clears carry the daily rate: copilot/fix-stringbytesroundtrip-no-op-alias fired 12 runs and 9 succeeded (75%) — a clean sweep across CWI, Running Copilot Code Review, Impeccable Skills Reviewer, Ponytail Reviewer, Test Quality Sentinel, PR Data Prefetch, Matt Pocock Skills Reviewer, PR Code Quality Reviewer, and Design Decision Gate. This single branch supplied 9 of today's 16 successes.
2. Agentic "Addressing comment on PR" runs remain the longest-running, highest-effort sessions: today's single instance ran 19.77 min (PR Split threat_detection_test.go, copilot_engine_test.go, maintenance_workflow_test.go by functional area #54681), consistent with the historical pattern (AWTC strategy, 07-08) that these agentic runs concentrate wall-clock effort far above gate stubs.
3. Orphan-free assignment discipline holds: all 20 currently open PRs have a Copilot assignee; 0 branches met the ≥5-gate / no-agent / >1h-wait escalation threshold.

Failure Signals ⚠️

1. Failures cluster on one branch: both of today's failures (CGO, CJS) landed on copilot/add-drive-memory-support (3 success / 2 failure = 60% pass rate) — the only branch with any failing gate today.
2. Aggregate completion% is misleading without per-branch decomposition: excluding the one branch that fully cleared its gate bundle, completion drops from 32% to 18.4% (7/38) — much closer to the historical floor regime (4–20% seen across 06-27→07-08). Four of six branches today show only a single agentic success against 3–11 pending/queued gate runs each.
3. Conversation-log gap persists: this is the 45th+ consecutive day (per repo memory) with no transcript data, so genuine behavioral failure signals (confusion, retries, tool errors) cannot be assessed — only CI/gate outcomes.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

N/A this run. Prompt/task-description text lives inside agent conversation transcripts, and logs/ returned zero *-conversation.txt files. No prompt-quality scoring, characteristic extraction, or before/after examples can be produced from workflow-run metadata alone. This has now held for 45+ consecutive analysis snapshots — see the conversation_log_fetch_failure pattern in repo memory for the full history.

Orphaned Branch Escalation Alerts 🚨

Branches with ≥5 simultaneous gate firings and no Copilot agent assigned for >1–2 hours.

Summary

• Orphaned Branches Today: 0 out of 20 open PRs (0%)
• Historical Baseline: repo-memory history shows a 0% orphan rate sustained for 43 consecutive recorded days (not the ~40% baseline in the standing template — that figure does not match this repository's actual observed history and should be corrected in the workflow template)
• Status: ✅ NORMAL

Escalation Candidate Details

Escalation Candidates

(No escalation candidates — all 20 open PRs are Copilot-assigned; live check via gh api repos/github/gh-aw/pulls + in-progress actions/runs found 4 active runs, none against an unassigned branch.)

CI Waste Estimate

• Orphaned gate-hours today: 0 (no orphaned branches to estimate against)

What we can observe (workflow-run metadata)

• 6 distinct branches active in the 32.4-min window: copilot/fix-logo-accessibility-issue (12 runs, 1 success), copilot/fix-stringbytesroundtrip-no-op-alias (12 runs, 9 success), copilot/require-sync-exec-timeout-fix (10 runs, 1 success), copilot/static-analysis-2026-08-22 (8 runs, 1 success), copilot/add-drive-memory-support (5 runs, 3 success/2 failure), copilot/deep-report-split-large-test-files (3 runs, 1 success).
• Longest-running run: "Addressing comment on PR Split threat_detection_test.go, copilot_engine_test.go, maintenance_workflow_test.go by functional area #54681" at 19.77 min (§32556770526).

Experimental Analysis

This run included experimental strategy: Branch-Level Gate Bundle Concentration

Prior experiments (Provenance Mapping/Inversion, Gate Footprint Signature Classification, Per-Branch Gate Fan-Out, AWTC) established that completion% is regime-dependent and that gate_count reflects PR-open events, not branch health. Today's data surfaces a related but distinct effect: a single branch fully clearing its gate/review bundle can swing the daily aggregate completion% by double digits.

Concretely: fix-stringbytesroundtrip-no-op-alias alone contributed 9 of 16 successes (56% of today's successes, 75% of its own 12 runs). Removing it from the denominator/numerator drops completion from 32.0% → 18.4% — nearly back to the 06-28→07-08 floor range (8–16%). Meanwhile add-drive-memory-support held 100% of today's failures.

Findings:

• Daily completion% cannot be trended meaningfully without per-branch decomposition; a single "lucky" branch can mask an otherwise-floor day.
• Failures are branch-concentrated, not spread across the sweep — worth checking if add-drive-memory-support's specific changes (not visible without conv logs) triggered both CGO and CJS gate failures for a shared root cause.

Effectiveness: High
Recommendation: Keep — add per-branch completion decomposition as a standard (non-experimental) metric in future runs, since it materially changes the interpretation of the trend line.

Actionable Recommendations

For Users Writing Task Descriptions

N/A this run — no conversation transcripts were available to assess prompt characteristics. This recommendation category will remain empty until the conversation-log fetch gap (45+ days running) is resolved.

For System Improvements

1. Fix the conversation-transcript fetch path: logs/ has returned 0 *-conversation.txt files for 45+ consecutive analysis runs per repo memory. This blocks every behavioral-analysis phase (tool usage, loop detection, prompt quality) that this workflow is designed to produce.
   • Potential impact: High — restores the workflow's core value proposition beyond CI-metadata reporting.
2. Correct the ~40% orphan-baseline assumption in the workflow template: actual observed history is a sustained ~0% orphan rate across 43+ days. Comparing today's 0% against a stale 40% baseline would incorrectly read as "elevated" in reverse (currently harmless since 0% < 40%, but the baseline itself should be corrected to avoid future false signals).
   • Potential impact: Medium — avoids misleading trend framing.
3. Add per-branch completion decomposition to the standard (non-experimental) metric set, per today's finding.
   • Potential impact: Medium — prevents single-branch effects from being read as aggregate quality trends.

For Tool Development

• No new tool gaps identified this run (no conversation logs to surface missing-tool requests from).

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: sparse/irregular sampling (8 recorded snapshots: 06-27, 06-28, 06-29, 07-03, 07-04, 07-05, 07-08, 08-22 — a 45-day gap precedes today). Values oscillate in a saw-tooth pattern between a ~2–20% floor and occasional spikes (40% on 06-27, 54% on 07-04, 32% today) rather than trending monotonically.
• Average duration trend: today's 2.64 min average is mid-range versus the 8-point history (0.19–3.83 min); execution-only mean (6.93 min, 19 non-zero runs) is consistent with prior "exec mean" values of 2.6–8.9 min on days with agentic activity.
• Quality improvement: not assessable — no prompt-quality or behavioral data this run.

Next Steps

• Investigate and fix the conversation-transcript fetch path (45+ day outage) so behavioral analysis (tool usage, loops, prompt quality) can resume
• Correct the workflow template's ~40% orphan-baseline reference to match observed ~0% history
• Add per-branch completion decomposition as a standing metric, not just an experimental one-off
• Consider whether add-drive-memory-support's CGO/CJS failures share a root cause (needs manual PR inspection — not visible from run metadata alone)
• Schedule follow-up analysis once conversation logs are restored

📈 Session Trends Analysis

Completion Patterns

Completion% is highly saw-toothed across the 8 recorded snapshots (2%–54%) rather than trending in one direction. Today's 32% is the second-highest on record, but per-branch analysis above shows it is largely a single-branch effect rather than a broad-based improvement — excluding that branch the rate would sit at 18.4%, in line with the historical floor.

Duration & Efficiency

No sessions with detected loops across any sampled date (loop detection itself is unavailable without conversation logs, so this reflects duration-based heuristics only). Average duration has been volatile (0.19–3.83 min) with no clear efficiency trend; the chart also makes visible the 45-day gap in recorded snapshots between 2026-07-08 and today.
