🤖 Copilot Agent Session Analysis — 2026-10-20

Executive Summary

• Sessions Analyzed: 50 (⚠️ wrong population — see Data Quality notice below)
• Analysis Period: 2026-10-20, 02:05:23Z – 06:21:36Z (~256 min window)
• Completion Rate: 72.0% (metadata-only; see caveat below)
• Average Duration: 2.51 min (CI-gate timing, not real agent-session duration)
• Experimental Strategy: none (standard run, roll=78)

⚠️ Data Quality Notice — Read First

This is the 3rd consecutive day of a data pipeline regression, and it has deepened:

• 0 of 50 conversation/event logs were fetched today (tied for the worst reading on record). No turn-by-turn transcripts were available, so no behavioral analysis (tool usage, token efficiency, loop detection, prompt quality) could be performed this run.
• The pre-fetched sessions-list.json population is not Copilot coding-agent sessions. All 50 entries are CI gate / check-run workflows: Agentic Commands, CJS, CWI, CGO, Stale Lock Files, Work Queue Compilation Integration, Doc Build - Deploy, Code scanning AI findings on PR #..., and Squad/Squad Implement Worker.
• New today: the population contains zero true-agentic workflow runs (no Addressing comment on PR..., no Running Copilot cloud agent, etc.) — only the 2nd zero-volume true-agentic day on record (the first was 2026-09-17).
• Recommendation (repeated, now urgent): the copilot-session-data-fetch shared module's run-selection filter should be reviewed — it has returned the wrong workflow-run population and 0 usable transcripts for three straight days, with the true-agentic share trending toward zero rather than recovering.

Everything below is computed from the available metadata only (conclusion, branch, timestamps) for trend continuity with prior daily snapshots. It should not be read as a behavioral assessment of actual Copilot coding-agent sessions.

Average Duration	2.51 min	↓ (vs 10-19: 8.01 min)
Median Duration	2.51 min	↑ (vs 10-19: 0.0 min)
Loop Detection Rate	N/A — no logs	—
Context Issues	N/A — no logs	—

Success Factors ✅

Behavioral success factors (prompt characteristics, tool usage patterns) cannot be assessed this run — 0/50 conversation logs were available, and the underlying population is CI-gate workflows rather than task-driven agent sessions with prompts to evaluate. The only factor visible from metadata:

1. Channel provenance: 100% of today's successes (36/36) came from the core-ci-gate (31) and code-scanning (5) channels — i.e., automated checks passing cleanly, not agent task completions.
   • Success rate: 100% within those two channels (31/39 core-CI-gate = 79.5%, 5/6 code-scanning = 83.3%)
   • Example: CJS, CWI, CGO runs on copilot/add-declarative-webhook-triggers resolving green.

Failure Signals ⚠️

1. Squad / Squad Implement Worker channel fully blocked: 5/5 runs ended action_required, 0% success — consistent with prior days where this channel is provenance-ambiguous and rarely resolves cleanly.
2. Branch concentration risk: copilot/add-declarative-webhook-triggers accounts for 60.0% (30/50) of all firings today — any systemic issue on this branch dominates the day's aggregate metrics.
3. Zero-duration stub runs: 13/50 sessions show identical created_at/updated_at (instant conclusion), which inflates apparent throughput without reflecting real execution time.

Note: these are CI-gate/metadata signals, not agent-behavior failure signals — the latter require the conversation logs that were unavailable today.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Not assessable this run. Prompt-quality analysis requires conversation transcripts (user task descriptions + agent turns), and 0/50 were available. Additionally, today's 50-item population consists of CI gate/check-run workflow firings, which do not have user-authored task prompts in the first place — this analysis dimension does not apply to the current population even when logs are present.

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 13 open PRs (0.0%)
• Historical Baseline: 0.0% orphaned rate (30-day mean over 30 recorded days)
• Status: NORMAL (today's rate does not exceed baseline + 20pts)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today. Highest observed gate footprint on any open-PR branch was 1 (on pelikhan-silver-telegram), well below the ≥5 threshold. Only 2 in-progress runs existed repo-wide at check time.

CI Waste Estimate

• Orphaned gate-hours today: 0 (no escalation candidates)
• Recoverable capacity: N/A — nothing to recover today

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Sessions with loops: N/A — requires conversation logs, unavailable today (0/50)

Tool Usage

• Most used tools: N/A — requires conversation logs
• Tool success rates: N/A — requires conversation logs
• Missing tools: N/A

Context Issues

• Sessions with confusion: N/A — requires conversation logs
• Common confusion points: N/A
• Clarification requests: N/A

Provenance (metadata-only substitute for behavioral tool-usage data)

• provenance_inversion pattern: today ties the all-time record at 100.0% bot-driven successes (36/36), matching 2026-09-16, 2026-09-17, and (at 97.0%) 2026-10-14. Unlike those prior record days, today also has zero true-agentic channel volume — a new wrinkle on this pattern, not previously seen except on 2026-09-17.
• Workflow mix: Agentic Commands (8), CJS (6), CWI (5), Stale Lock Files (5), Work Queue Compilation Integration (5), CGO (5), Doc Build - Deploy (5), Code scanning AI findings (6, across 3 PRs), Squad/Squad Implement Worker (5).

Experimental Analysis

Standard analysis only — no experimental strategy this run (roll=78, ≥30 threshold). Experimental analysis was again deprioritized in favor of documenting the data pipeline regression, which remains the primary actionable finding for a third consecutive day.

Actionable Recommendations

For Users Writing Task Descriptions

Not applicable this run — no agent task prompts were present in today's population to evaluate (see Data Quality Notice).

For System Improvements

1. Fix copilot-session-data-fetch run-selection filter: for 3 consecutive days (2026-10-18 partial, 2026-10-19, 2026-10-20) the module has returned CI gate/check-run workflows instead of Copilot coding-agent sessions, and conversation-log retrieval has degraded from 1-3/50 to 0/50. The true-agentic share has gone from 5/5→2/2→0/0 over the same three days — this looks like a widening regression, not noise.
   • Potential impact: High — without a fix, behavioral analysis (the core purpose of this workflow) remains impossible.
2. Add a population sanity check: if a day's "sessions" are ≥90% recognizable CI-gate/check-run workflow names, the workflow should flag this explicitly before running the full analysis pipeline, as happened manually here.
   • Potential impact: Medium — faster detection of future regressions.

For Tool Development

1. No new tool gaps identified this run — the missing capability is upstream data-fetch correctness, not a missing analysis tool. missing_data has been the appropriate mechanism to signal this for prior cycles and continues to be the right signal; today's report documents it inline instead per workflow mission context (no GitHub issue tooling enabled this run, see Data Quality Notice).

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: 68.0% (10-18) → 66.0% (10-19) → 72.0% (10-20): +6pts day-over-day, 2nd-highest of 48 recorded days (behind 2026-09-02's 78.0%). 47-day prior mean is 35.0% (range 4–78%), so recent days are running well above the longer-term average — largely because the dominant population lately is CI-gate workflows, which resolve green far more often than genuine agent task completions.
• Average duration trend: 18.49 min (10-18) → 8.01 min (10-19) → 2.51 min (10-20): declining, consistent with CI-gate instant-fire timing rather than any genuine agent-session efficiency gain.
• Data availability trend: conversation logs 1/50 (10-18) → 0/50 (10-19) → 0/50 (10-20) — no improvement; true-agentic channel volume 5 (10-18) → 2 (10-19) → 0 (10-20) — actively worsening.

📈 Session Trends Analysis

Completion Patterns

Completion rate has climbed for two straight days (66.0% → 72.0%) and now sits 2nd-highest of 48 recorded days, but the underlying population shift to CI-gate workflows means this reflects automated checks passing cleanly rather than improving agent task performance. The historical swings (lows near 10-20%, highs near 78%) track changes in which workflow types dominate a given day's sample far more than any genuine quality trend.

Duration & Efficiency

Average session duration fell sharply to 2.51 minutes, the tightest mean/median gap seen in weeks, driven by the CI-gate-dominated population resolving quickly rather than any efficiency improvement in agent sessions. The loop-count overlay could not be populated — conversation/event logs needed for loop detection have now been unavailable for 3 consecutive days.

Next Steps

• Review and fix the copilot-session-data-fetch module's run-selection filter — 3rd consecutive day of 0 usable logs and wrong population, with true-agentic volume now at zero
• Add an automated population sanity check to flag CI-gate-dominated days before full analysis runs
• Re-run behavioral analysis (tool usage, loop detection, prompt quality) once the fetch module is fixed and genuine agent-session transcripts are available
• Continue monitoring orphaned-branch escalation (currently healthy, 48 consecutive NORMAL days)
