[copilot-session-insights] Daily Copilot Agent Session Analysis — 2026-05-16

[github-actions[bot]]

Executive Summary

• Sessions Analyzed: 50
• Analysis Period: 2026-05-16 05:31Z → 06:44Z (~73 min window)
• Completion Rate: 8.0% (4 success / 46 action_required)
• Copilot Agent Success: 2/2 success (100%) for branches where the agent ran
• Data Quality: infrastructure-only — conversation transcripts still unavailable (8th consecutive day; today's log is a 1-line gh auth login OAuth error)

Key Metrics

Metric	Value	Trend vs. 7-day window
Total Sessions	50	→
Successful Completions	4 (8.0%)	↑ from 0% on 2026-05-13
Failed / action_required	46 (92%)	↓ from 100% on 2026-05-13
Unique Branches	6	↑ from 4
Copilot Agent Runs	2 (both succeeded)	↓ from 4
Spec Orphans (≥5 gates + no agent + >1h)	0	→ (6+ consecutive days)

Success Factors ✅

1. Copilot agent on active gate-sweep branches: Both 17- and 16-gate branches (update-claude-code-and-mcp-gateway, refactor-git-patch-header-parsing) had successful Running Copilot cloud agent completions. Gate concentration + agent presence = success path.
2. Haiku Printer auto-merge candidates: 2/2 Haiku Printer runs succeeded — consistent with the existing Gate Workflow Composition Fingerprinting strategy (Haiku-only = auto-merge candidate).
3. Templated branches stay small: aw-compat-daily-summary-2026-05-16, remove-stub-init-functions, fix-gh-aw-workflows-dir-override each have ≤4 gates — tight scope, low risk.

Failure Signals ⚠️

1. Pre-agent gate dominance persists: 92% of sessions still in action_required — same pattern as 2026-05-13 (100%) and consistent with the 7-day infrastructure-only trend.
2. Sweep-after-success pattern: Both successful Copilot runs were followed within ~10 s by a 5-fire gate burst (e.g. 06:14:22Z success → 06:14:24Z 5-fire burst on the same branch). Indicates downstream gates re-trigger after the agent push without converging.
3. Workflow concentration unchanged: Agentic Commands + Q together account for 26/50 firings (52%) — identical concentration profile to 2026-05-13.

Prompt Quality Analysis 📝

No conversation transcripts available, so prompt-quality scoring is not possible this run (8th consecutive day). Branch-name heuristics only:

• Specific intent (fix-lockdown-check-fails, refactor-git-patch-header-parsing, remove-stub-init-functions): 4/6 branches — clear scope signal.
• Versioned/templated (aw-compat-daily-summary-2026-05-16, update-claude-code-and-mcp-gateway): 2/6 — auto-generated / routine.

Orphaned Branch Escalation Alerts 🚨

Summary

• Spec orphans today (≥5 gates + no agent + >1h): 0 out of 12 open PRs
• Naive orphans (no assignee, any gate count): 5 / 12 (41.7%) — all chaos/* test branches with 0 active gates
• Historical baseline: ~40%
• Status: ✅ NORMAL (true orphan threshold = 0; 6+ consecutive days)

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. All ≥5-gate branches have Copilot assigned.

CI Waste Estimate

• Top 2 branches (update-claude-code-and-mcp-gateway, refactor-git-patch-header-parsing) absorb 33/50 firings (66%) but both have an agent in flight; not waste, just queue depth.
• Chaos/* PRs (5) have no agent but 0 gate firings — no recoverable CI capacity.

Burst pattern (groups of simultaneous firings)

3 size-5 bursts (all single-branch), 1 size-3 burst, plus scattered size-2 bursts. Same as 2026-05-12 fingerprint: small bursts dominate, no single mega-sweep. Both top branches' size-5 bursts fire within seconds of their respective Running Copilot cloud agent success — confirms the sweep-after-success pattern.

📈 Session Trends Analysis

Completion Patterns

Completion rate has oscillated 0–16% across the last 8 reported days; today's 8% sits at the median. The action_required share remains the volatile metric — 92% today, down from the 100% spike on 2026-05-13 but still well above the early-May 84% baseline.

Duration & Efficiency

Copilot agent count dropped to 2 (lowest since 2026-05-12). Average duration is N/A today because completed-run timestamps in the session list collapse created_at == updated_at — the existing Temporal Analysis strategy needs richer timing data to keep producing the duration trendline.

Experimental Analysis

Standard analysis only — no experimental strategy this run. (RNG below 30% threshold not triggered.)

Actionable Recommendations

For Users Writing Task Descriptions

1. Keep using specific-intent branch names — fix-lockdown-check-fails and refactor-git-patch-header-parsing both attracted Copilot agents and one converged to success.
2. Avoid leaving chaos/* PRs open without an assignee — they don't generate orphan escalations (0 gates), but they inflate the naive orphan rate (41.7%) and obscure real orphan signals.

For System Improvements

1. Fix conversation-transcript fetch (8-day open issue): the gh auth login OAuth path is the persistent blocker — without it, this workflow cannot do behavioral analysis as designed. Impact: High.
2. Add a sweep-after-success detector: gates re-firing within ≤30 s of a Running Copilot cloud agent success indicate non-converging post-merge checks. Impact: Medium.
3. Track gate-survives-agent ratio: today both top branches have an active agent AND 16–17 stuck gates — strict orphan filter misses this dominant waste mode. Impact: Medium.

For Tool Development

1. Conversation-transcript access without OAuth re-auth: blocked 8 consecutive runs. Without it, prompt-quality scoring and loop detection are inert.
2. Per-run duration in sessions-list.json: created_at == updated_at for completed runs prevents duration trend computation.

Trends Over Time

• Completion-rate trend: 0% → 8% → 0% → 8% → 16% → 0% → 8% (May 7,8,10,11,12,13,16) — no monotonic direction; oscillates 0–16%.
• Agent count trend: 6 → 19 → 1 → 4 → 5 → 1 → 4 → 2 — declining since 2026-05-11.
• Agent-success rate when measurable: 100% on 4 of the last 5 days where transcripts surfaced; the 57.9% dip on 2026-05-07 remains the outlier.

Next Steps

• Investigate the persistent gh auth login OAuth error blocking conversation-transcript fetch (8 consecutive days)
• Consider adding a "sweep-after-success" metric to capture today's pattern on both top branches
• Schedule follow-up analysis tomorrow (2026-05-17)
