🤖 Copilot Agent Session Analysis — 2026-08-18

⚠️ Data availability notice

Two data gaps affected this run, disclosed up front so the metrics below are read with the right confidence:

1. Conversation transcripts were empty — find /tmp/gh-aw/agent/session-data/logs -name "*-conversation.txt" returned 0 files. This has now been true for ~83+ consecutive tracked days (per repo-memory, first noted 2026-06-23, still empty 2026-07-08, still empty today). Turn-by-turn tool usage, token efficiency, loop detection, and prompt-quality analysis (Phase 1, most of Phase 3) are not possible with this run's inputs — see missing_data call below.
2. The analysis pipeline itself had a 41-day gap — the last entry in repo-memory (session-trends.jsonl, session-analysis-history.json) is dated 2026-07-08; this is the first run since then. That's a new, separate finding worth escalating: not just the log-fetch step but the whole daily analysis job appears to have stopped firing for over a month.

What is real and derived from live data this run: the 50-row workflow-run metadata list (sessions-list.json), and a live gh api sweep for the orphaned-branch escalation check (Phase 2b).

Executive Summary

• Sessions Analyzed: 50 workflow runs (metadata only — 6 are actual "Running Copilot cloud agent" sessions; 43 are CI gate-workflow stubs; 1 in-progress)
• Analysis Period: 61-minute window, 2026-08-18 05:42–06:42 UTC (not 30 days — see gap notice)
• Completion Rate: 12% (6/50)
• Average Duration: 1.26 min (all runs, dominated by 0-duration gate stubs); 10.29 min (executed agent runs only)
• Experimental Strategy: none this run (roll=86 ≥ 30 → standard run)

Success Factors ✅

1. Provenance inversion holds (9th+ consecutive observation): 100% of successes (6/6) came from the "Running Copilot cloud agent" workflow — real agent execution — on branches copilot/eslint-factory-fix-page-counter-increment, copilot/static-analysis-report-2026-08-18, copilot/fix-eslint-factory-false-positive, copilot/sighthound-security-findings-again, copilot/rgs-016-remove-unicode-characters, copilot/ci-coach-fix-unit-test. Durations ranged 7.4–14.2 min.
   • Success rate from this workflow today: 6/6 (100% of its runs)
2. CI gate workflows never contribute a "success" conclusion on gate-sweep days: all 43 action_required runs are 0-duration stubs from Agentic Commands (22), Content Moderation (6), AI Moderator (6), CWI (4), CGO (4), Stale Lock Files (1) — these are approval gates, not agent work, and inflate the raw run count without reflecting agent quality.
3. Every open PR has an assigned agent: all 11 open PRs list Copilot as an assignee, so none qualify as "orphaned" regardless of gate footprint.

Failure Signals ⚠️

1. Denominator distortion: because 86% of today's 50 "sessions" are instant CI gate stubs, the raw 12% completion rate understates real agent throughput — this has been a recurring pattern (documented in memory as provenance_inversion since 2026-06-07).
2. Data-pipeline fragility: the 41-day silent gap in this very analysis job, layered on the pre-existing 83-day conversation-log fetch failure, means both the deep (turn-level) and the meta (is-this-workflow-running) signals have had blind spots.
3. Concentration on one branch: copilot/sighthound-security-findings-again accounts for 11/50 runs (22%) — largely CI gate re-fires rather than agent iterations, consistent with the previously observed "gate fan-out on PR-open" pattern, not evidence of the agent looping.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Not assessable this run — prompt text and task descriptions live in the conversation transcripts, which were not fetched (0 files). No high/medium/low-quality prompt classification can be produced without them. This has been true for every run traced in memory back to 2026-06-23.

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 11 open PRs (0%)
• Historical Baseline: ~40% orphaned rate (per repo-memory)
• Status: ✅ NORMAL (well under the 50% elevated-waste threshold)

Escalation Candidate Details

Live gh api sweep (11 open PRs, 9 in-progress workflow runs in the last 6 hours):

Branch	PR	Gate Count	Assignees	Severity
copilot/add-support-safe-output-pr	#53576	1	pelikhan, Copilot	none
copilot/refactor-semantic-clustering	#53564	1	pelikhan, Copilot	none
copilot/fix-no-bash-workflow-safeoutputs	#53548	1	pelikhan, Copilot	none
copilot/fix-copilot-cli-toolcache-issue-again	#53490	1	pelikhan, Copilot	none
(7 other open PRs)	—	0	pelikhan, Copilot	none

✅ No orphaned branches exceed the escalation threshold today — every branch with an active gate is already Copilot-assigned, and the maximum simultaneous gate count on any single branch (1) is far below the ≥5 escalation trigger.

CI Waste Estimate

• Orphaned gate-hours today: 0 (no qualifying branches)
• Recoverable capacity: n/a — no orphaned capacity detected

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Not measurable this run (requires conversation logs).

Tool Usage

• Not measurable this run (requires conversation logs).

Context Issues

• Not measurable this run (requires conversation logs).

Pipeline health (new observation)

• The analysis pipeline that produces this discussion went silent for 41 days (2026-07-08 → 2026-08-18) based on repo-memory's last_updated fields. If this recurs on the next run, it points to the trigger/schedule breaking, not just the log-fetch step — worth checking the workflow's cron/schedule configuration and recent run history directly.

📈 Session Trends Analysis

Completion Patterns

Only 8 data points exist across the tracked history (2026-06-27 through today), with a 41-day blank gap annotated on the chart — this is not a continuous 30-day trend, so read it as a sparse sample, not a smooth series. Within that sample, completion rate oscillates in a "saw-tooth" pattern between a ~2–16% floor and occasional spikes (40%, 54%) that memory attributes to regime shifts in which workflow type (CI gates vs. agent runs) happens to report "success" that day. Today's 12% sits in the floor band, consistent with the last four tracked days.

Duration & Efficiency

Mean duration across all runs stays low (~1–4 min) because it's dominated by 0-duration gate stubs; mean duration across executed runs only (the real agent sessions) has been trending up across the last three tracked points — 6.7 → 2.6 → 8.85 → 10.29 min — though with only 4 non-gap points this is a thin trend, not a confirmed one.

Experimental Analysis

Standard analysis only this run (roll=86 ≥ 30 threshold) — no experimental strategy applied. Prior experiments remain in memory: Success-Workflow Provenance Mapping/Inversion, Gate Footprint Signature Classification, Per-Branch Gate Fan-Out Fingerprinting, Approval-Gate Saturation Ratio, Gate-Bundle Composition Divergence, Bimodal Gate-Sweep Inversion, and Agentic Work-Time Concentration (AWTC) — all rated Medium-High to High effectiveness.

Actionable Recommendations

For System Improvements

1. Fix the conversation-log fetch (highest priority, unchanged from every prior report): the copilot-session-data-fetch module has produced 0 transcript files for ~83 consecutive tracked days. This blocks the workflow's core stated mission (turn-by-turn behavioral analysis) entirely — every report since 2026-06-23 has been metadata-only.
   • Potential impact: High — unblocks Phase 1, most of Phase 3, and prompt-quality analysis.
2. Add a "did this workflow run yesterday?" self-check: the 41-day gap in this very pipeline went undetected until this run manually diffed timestamps. A simple guard (compare today's date to last_updated in cache/repo-memory, alert if the gap exceeds ~36–48h) would catch pipeline-trigger failures independently of the log-fetch issue.
   • Potential impact: Medium — improves observability of the observability tool itself.
3. Separate CI gate workflows from agent-session metrics at the source: since gate stubs consistently make up 80–90% of the "sessions" list and never contribute turn-level signal, consider having the fetch module tag/filter them so completion-rate and duration metrics reflect agent work directly instead of requiring after-the-fact provenance analysis every run.
   • Potential impact: Medium — removes a recurring manual-correction step from every analysis.

For Tool Development

1. Conversation-log export for cloud-agent runs: 6 sessions today (Running Copilot cloud agent) ran 7.4–14.2 minutes of real agent work with zero transcript captured. Exporting even a coarse turn/tool-call log for these specific runs would immediately restore Phase 1 capability without needing to fix every workflow type.
   • Frequency of need: every run, 83+ consecutive days
   • Use case: loop detection, tool-usage patterns, prompt-quality correlation

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: saw-tooth, no sustained direction; today's 12% is within the recent floor band (4–16%) seen since late June/early July.
• Average duration trend: executed-run duration has increased across the last 4 tracked points (6.72 → 2.58 → 8.85 → 10.29 min), but the series has too many gaps to call this a confirmed trend.
• Orphan rate: stable at 0% for at least the last 8 tracked days (~43rd consecutive "healthy" day per repo-memory), against a documented ~40% historical baseline — the discrepancy suggests either genuinely good agent-assignment hygiene in this window, or that the "baseline" figure needs revisiting.

Next Steps

• Investigate why the conversation-log fetch has returned 0 files for ~83 consecutive tracked days
• Investigate why this analysis workflow itself did not run between 2026-07-08 and 2026-08-18
• Add a pipeline-liveness self-check to catch future scheduling gaps automatically
• Re-run analysis once conversation logs are restored to unlock turn-level behavioral insights
