🤖 Copilot Agent Session Analysis — 2026-06-21

Executive Summary

• Sessions Analyzed: 50 (CI workflow runs across 4 copilot/* branches)
• Analysis Period: 2026-06-21 05:03–05:56Z (53-minute capture window)
• Completion Rate: 24% (12/50) — highest since 2026-06-13 (38%), 4× the prior 7-day average (~6%)
• Average Duration: 2.4 min all-50 / 9.25 min for the 13 sessions that actually executed
• Experimental Strategy: None this run (standard analysis; roll 52 ≥ 30 threshold)
• Headline: The pure gate-sweep bimodal pattern broke — 8 of 12 successes are CI gate workflows that passed green, not just cloud-agent/comment runs.

Key Metrics

Nonzero-Duration Sessions	13 (26%)	↑ (2-week high in share)
Loop Detection Rate	Not measurable	—
Context Issues	Not measurable	—
Orphaned Branches	0 (0%)	→ (31st consecutive healthy day)

Data-quality caveat: Conversation transcripts remain unavailable for the 28th+ consecutive day (OAuth token error). All findings below are derived from CI/run metadata only — behavioral, loop, context-confusion, and prompt-quality analysis cannot be performed this run.

Success Factors ✅

1. CI gates resolving green (not just firing): 8/12 successes were gate workflows — CGO ×2, Smoke CI ×2, CJS, Agentic Commands, Doc Build-Deploy — that completed successfully. On recent days these same workflows ended in action_required (fired-and-waiting). Today they passed, indicating the lead branches reached a CI-clean state.
2. Concentrated, agent-assigned branches: 88% of activity on 2 branches (aw-code-simplifier-failure-fix 68% / 8 successes, copilotupdate-conclusion-job-aggregate-data 20% / 4 successes), both with Copilot + pelikhan assigned (PRs code simplifier: allowed_issue_fields.cjs; remove drain3_server.py #40578, Align Smoke Copilot prompts with actual tool names #40576). Concentration on assigned branches continues to correlate with higher completion.
3. Comment-addressing reliability: Both Addressing comment on PR runs (Align Smoke Copilot prompts with actual tool names #40576 @ 12.6 m, code simplifier: allowed_issue_fields.cjs; remove drain3_server.py #40578 @ 11.4 m/8.2 m) succeeded — consistent with the historical comment-addressing success-floor (≥8 min).

Failure Signals ⚠️

1. Gate-firing noise still dominates: 37/50 (74%) ended action_required at 0-duration — CI gates triggered awaiting checks, dragging all-50 averages down (median 0). This is gating friction, not agent failure.
2. Secondary branches yielded nothing: aw-fix-daily-compiler-workflow (4 runs) and update-conclusion-job-aggregate-data (2 runs) produced 0 successes — low-footprint branches still showing the inverse success-density-vs-gate-footprint relationship.
3. Sub-floor code-review successes: 2 Running Copilot Code Review successes at 3.6/4.9 min — below the ≥8 min success floor, the recurring code-review/printer provenance exception.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Prompt-quality scoring requires the agent conversation transcripts, which are unavailable for the 28th+ consecutive day (OAuth). No per-prompt characteristic breakdown can be produced this run. This remains the single longest-running unresolved data gap in the workflow and continues to block all internal-monologue, loop-count, and context-confusion analysis.

Recommendation: Restoring transcript fetch (OAuth re-authorization in the copilot-session-data-fetch module) is the highest-leverage fix to re-enable behavioral analysis.

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 7 open PRs (0%)
• Historical Baseline: ~40% orphaned rate
• Status: ✅ NORMAL (well below the 50% elevated-waste threshold; 31st consecutive healthy day)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today.

All 3 in-progress workflow runs are on main (housekeeping/analysis workflows), so no copilot/* branch carries an active gate sweep. The 3 copilot/* open PRs (#40578, #40576, #40423) are all Copilot-assigned; the 4 remaining open PRs are unassigned housekeeping branches (security-fix #40599, dictation-glossary #40593, jsweep #40584, caller-permissions #40175) with 0 gate firings each — idle, not orphaned.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no recoverable wasted CI capacity.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Sessions with loops: Not measurable (no conversation transcripts).
• All loop/iteration metrics unavailable for the 28th+ consecutive day.

Tool Usage

• Tool-call traces require transcripts; unavailable. Gate-workflow footprint (from run metadata): Agentic Commands 10, Q 10, Smoke CI 4, CJS 3, CGO 2, plus single-fire reviewers (Design Decision Gate, Test Quality Sentinel, PR Code Quality Reviewer, Matt Pocock Skills Reviewer).

Context Issues

• Not measurable without transcripts.

Duration Distribution

• 13/50 sessions nonzero (26% — highest share in ~2 weeks); nonzero avg 9.25 min, nonzero median 9.02 min, max 12.62 min. Remaining 37 are 0-duration gate firings.

Experimental Analysis

Standard analysis only — no experimental strategy this run (roll 52 ≥ 30% threshold).

📈 Session Trends Analysis

Completion Patterns

After three near-floor days (06-17 @ 0%, 06-18 @ 4%, 06-19 @ 6%, 06-20 @ 0%), completion jumped to 24% — the strongest rung since the 06-13 spike (38%). The saw-tooth oscillation persists, but today's recovery is driven by genuine gate-green successes rather than the single-cloud-agent successes that carried prior up-days.

Duration & Efficiency

All-50 average duration (2.4 min) rises with the success count, but the more meaningful signal is the 13 sessions that actually executed, averaging 9.25 min — a healthy run length consistent with real agent work. Loop/retry counts remain unplottable because conversation logs are still unavailable.

Actionable Recommendations

For Users Writing Task Descriptions

1. Keep iteration concentrated on assigned branches — the two top branches (88% of activity, both Copilot-assigned) account for all 12 successes; scattered low-footprint branches yielded none.
2. Reference the specific failing gate — branches that reached CI-green today did so by resolving named gates (CGO, CJS, Smoke CI); task descriptions that name the failing check converge faster.

For System Improvements

1. Restore conversation-transcript fetch (OAuth) — Impact: High. 28+ days without transcripts blocks all behavioral, loop, and prompt-quality analysis; this is the top fix.
2. Reduce 0-duration gate-firing noise in the session feed — Impact: Medium. 74% of "sessions" are gate triggers awaiting checks, not agent runs; filtering or tagging them would sharpen completion-rate signal.

For Tool Development

1. Transcript availability probe — surface OAuth/transcript fetch health as an explicit signal so metadata-only degradation is flagged at fetch time rather than inferred (needed 28+ sessions running).

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate: oscillatory saw-tooth over 30 days (spikes 06-10 @40%, 06-13 @38%, today @24%; troughs 0–6%). No sustained multi-day recovery yet.
• Average duration: tracks success count (bimodal — long real runs vs. 0-duration gate sweeps).
• Orphan rate: 0% for ~31 consecutive days vs. ~40% historical baseline — sustained healthy assignment hygiene.

Statistical Summary

Successful Completions:      12 (24%)
Action-Required (gates):     37 (74%)
Skipped:                     1 (2%)
Failed/Cancelled:            0 (0%)

Nonzero-Duration Sessions:   13 (26%)

Loop Detection:              not measurable (no transcripts)
Context Issues:              not measurable (no transcripts)

Orphaned Branches:           0 of 7 open PRs (0%, baseline ~40%) — NORMAL
Capture Window:              53 min (05:03–05:56Z)
Branch Concentration:        top-2 = 88%

Next Steps

• Restore conversation-transcript fetch (OAuth) to re-enable behavioral analysis
• Watch whether the 24% gate-green recovery holds for a 2nd consecutive day (would break the oscillation)
• Continue monitoring orphan rate against the 40% baseline
• Schedule follow-up analysis in 24 hours
