🤖 Copilot Agent Session Analysis — 2026-08-17

Executive Summary

• Sessions Analyzed: 50 (workflow-run metadata only — see data-quality note below)
• Analysis Window: 2026-08-17 05:18–06:46 UTC (88.5 min)
• Completion Rate: 6% (3/50) — floor regime, consistent with the last ~2 months
• Average Duration: 0.84 min overall (dragged to ~0 by 46 zero-duration CI gate stubs); 13.94 min average among the 3 executing sessions
• Experimental Strategy: Agentic Session Duration Drift (ASDD) — triggered (roll=25/100 < 30)

⚠️ Data-quality note: Conversation transcripts ({run_id}-conversation.txt) were empty for all 50 sessions — the same failure mode logged in repo memory for 60+ consecutive observed days (conversation_log_fetch_failure). Turn-by-turn tool usage, token efficiency, loop detection, and prompt-quality scoring are not assessable this cycle. Everything below is derived from GitHub Actions run metadata (sessions-list.json: status/conclusion/timestamps/branch) plus live PR and workflow-run queries, following the "metadata-only" methodology established in prior runs.

Orphaned Branches	0 / 11 open PRs	→ (0% orphan rate, healthy streak continues)

📈 Session Trends Analysis

Completion Patterns

Today's 6% completion sits inside the floor band (4–20%) this workflow has oscillated in since late June, well below the ~30d historical mean (~13%). Only 9 snapshot dates exist across the last ~2 months (repo-memory history retention has trimmed the rest), so this is a sparse spot-check series, not a continuous daily trend — read direction, not precision.

Duration & Efficiency

The overall average stays pinned near zero because ~92% of daily volume is 0-duration CI gate stubs, not agent work. Restricted to the sessions that actually executed, duration has trended upward across the last four data points (6.72 → 2.58 → 8.85 → 13.94 min) — see the ASDD experiment below for why this is a lead, not yet a conclusion.

Success Factors ✅

1. Provenance inversion holds (60+ day streak): All 3 successes today are agentic runs — "Addressing comment on PR Split long CLI logs/reporting functions into focused helpers #53279" (15.3 min) and 2× "Running Copilot cloud agent" (14.0, 12.6 min). None of the 9 CI gate workflow types observed today (AI Moderator, Agentic Commands, CGO, CJS, CWI, Content Moderation, Doc Build - Deploy, Extension Upgrade Test, Stale Lock Files) produced a single success conclusion — all 46 of their runs are action_required gate stubs.
2. Copilot-assignment eliminates orphan risk: All 7 branches with active gate footprint (5–8 CI runs each) are assigned to the Copilot agent. 0 escalation candidates today.
3. Gate footprint scales with change surface, not branch age: the two lint-monster-* refactor branches and aw-fix-* branches each carry 6–8 gate runs; a lighter definitions/docs branch (add-definitions-agentic-engine) carries only 5 — consistent with the previously-documented "Gate-Bundle Composition Divergence" pattern (bundle size is change-type-adaptive).

Failure Signals ⚠️

1. Metric dilution by CI noise: 92% of daily "sessions" are 0-duration gate-check stubs (action_required), not agent work. The headline 6% completion rate is mostly a measure of gate-to-agent-session ratio, not agent quality (per "Success-Workflow Provenance Mapping", tested 2026-06-03).
2. Rising executing-session duration: 13.94 min today is the highest in the observed series, 2.3× the trailing 3-snapshot average (6.05 min). With only 2–3 executing sessions per snapshot, this could reflect real complexity growth or simple small-sample noise — flagged, not confirmed (see ASDD below).
3. Conversation-log fetch failure, now 60+ days: this remains the single largest blind spot for this workflow — no loop detection, tool-usage, token-efficiency, or prompt-quality analysis has been possible since it began.

Prompt Quality Analysis 📝

Not assessable this cycle

Prompt-quality scoring, high/low-quality characteristic breakdown, and example prompts all require conversation transcript content, which is empty for all 50 sessions. Fabricating percentages here would misrepresent the analysis. This section will populate automatically once the conversation-log pre-fetch is fixed (tracked as conversation_log_fetch_failure in repo memory since at least 2026-06-something, 60+ days running).

Orphaned Branch Escalation Alerts 🚨

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

Summary

• Orphaned Branches Today: 0 / 11 open PRs (0%)
• Historical Baseline: ~0% observed baseline over the last several months (not the generic ~40% default) — this repo has been in a healthy streak since at least May 2026
• Status: ✅ NORMAL

Escalation Candidate Details

No escalation candidates. Of the 11 open PRs: 7 are Copilot-assigned and map 1:1 to the 7 branches carrying gate activity (5–8 runs each, all accounted for by normal per-push CI/agent execution). The remaining 4 open PRs (feat/schema-demo-enclaves-coverage-*, go-test-parallelizer-*, lpcox-document-security-profiles, lpcox-simplify-github-access) are unassigned but have zero active CI runs in the trailing 6-hour window — no gate pressure, so no escalation regardless of assignment.

CI Waste Estimate

• Orphaned gate-hours today: 0 (no qualifying branches)
• All 4 in-progress runs observed in the 6h window are on main (PR Sous Chef, Code Scanning Fixer, Failure Investigator, this analysis workflow) — no branch-level gate backlog exists to recover.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Not assessable — requires conversation transcripts (empty this cycle, as every cycle for 60+ days).

Tool Usage

• Not assessable at the agent-tool level. At the CI-workflow level, the 46 gate stubs break down as: Agentic Commands ×24, AI Moderator ×4, Content Moderation ×4, CGO/CJS/CWI ×3 each, Stale Lock Files ×3, Doc Build - Deploy ×1, Extension Upgrade Test ×1 — all action_required, none executed to a conclusion.

Context Issues

• Not assessable — requires conversation transcripts.

Experimental Analysis

This run included experimental strategy: Agentic Session Duration Drift (ASDD)

Building on the prior "Agentic Work-Time Concentration" (AWTC, 07-08) finding that nearly all real compute-time lives in a handful of agentic runs, ASDD asks whether those runs are getting longer over time — a proxy for growing task complexity or slipping efficiency, independent of the noisy gate-stub-dominated completion percentage.

Method: ratio of today's executing-session mean duration to the trailing mean of the prior 3 snapshots that had executing sessions.

Findings:

• Executing-session mean duration across the last 4 observed data points: 6.72 min (07-04) → 2.58 min (07-05) → 8.85 min (07-08) → 13.94 min (08-17).
• ASDD ratio today: 13.94 / 6.05 (trailing 3-snapshot mean) = 2.30×.
• Direction is upward across 3 of the last 4 points, but sample size per snapshot is only 2–3 sessions, and snapshots themselves are weeks apart (not daily) — too sparse to separate a real complexity trend from noise.

Effectiveness: Medium — directionally interesting, not yet actionable.
Recommendation: Refine. Track ASDD every run (not just when this analysis happens to fire) and require ≥5 executing sessions in a window before treating drift as a real signal rather than variance.

Actionable Recommendations

For Users Writing Task Descriptions

• No new data-driven guidance this cycle (prompt content unavailable). Standing guidance from prior cycles still applies: reference specific files/branches and state the expected outcome explicitly — historical snapshots (when logs were briefly available) showed these correlate with higher completion.

For System Improvements

1. Fix the conversation-log pre-fetch — 60+ consecutive days with 0/50 transcripts populated. This is the highest-impact fix available: it unblocks every turn-level metric this workflow is designed to produce (loop detection, tool-usage, token efficiency, prompt-quality). Potential impact: High.
2. Tighten repo-memory history retention — only 9 snapshot dates survive across ~2 months of runs, producing sparse, gapped trend charts instead of a real daily series. A lightweight daily rollup (a few fields, not full session dumps) would fit the 10KB/patch budget while preserving cadence. Potential impact: Medium.

For Tool Development

• Missing capability: programmatic access to actual Copilot agent conversation transcripts for this repo's sessions. Frequency of need: every run (50/50 sessions, 60+ days). Use case: all Phase 1 behavioral analysis in this workflow's spec.

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate: oscillating floor regime (2–20%) with one outlier spike to 54% on 07-04, since reverted. Today's 6% is within the floor band, slightly below the last recorded 8% (07-08).
• Average duration: overall average has stayed under 4 min at every snapshot (gate-stub-dominated); executing-session average is trending up (see ASDD).
• Orphan rate: 0% at every snapshot observed — a long, unbroken healthy streak.

Next Steps

• Prioritize the conversation-log pre-fetch fix — this is now a 60+ day-old open issue blocking the workflow's core purpose
• Consider a lighter daily history rollup so trend charts have real daily cadence instead of sparse spot-checks
• Re-run ASDD once ≥5 executing sessions are available in a single window to confirm or reject the duration-drift signal
• Continue monitoring orphan rate (currently 0%, healthy) — no action needed today
