🤖 Copilot Agent Session Analysis — 2026-08-30

Executive Summary

• Sessions Analyzed: 50 GitHub Actions workflow runs (gate/review/agentic), across 5 copilot/* branches
• Analysis Period: 2026-08-30, 05:52–06:34 UTC (a single 41-minute burst window — see caveat below)
• Completion Rate: 22% (11/50)
• Average Duration: 2.45 min (all runs) / 10.23 min (12 non-zero-duration "executed" runs only)
• Experimental Strategy: none — standard analysis only this run

⚠️ Data-quality caveat (carried forward from prior runs): conversation transcript logs ({run_id}-conversation.txt) are empty for the 46th+ consecutive recorded day. sessions-list.json also shows these "sessions" are GitHub Actions workflow runs (CI gates, review bots, agentic maintenance jobs), not distinct Copilot agent conversations with turn-by-turn tool calls. All findings below are metadata-only (conclusion/timing/branch/workflow-name) — loop detection, prompt-quality scoring, and context-confusion analysis are not measurable this run, as in every recorded run before it.

Key Metrics

Metric	Value	Trend
Total Sessions	50	→ (fixed daily sample size)
Successful Completions	11 (22%)	↑ (+4pts vs 08-29's 18%)
Failed/Abandoned	39 (78%) — 38 action_required stubs + 1 failure	↓ correspondingly
Average Duration	2.45 min	↓ (vs 3.80 min on 08-29)
Loop Detection Rate	not measurable	— (conversation logs unavailable)
Context Issues	not measurable	— (conversation logs unavailable)

Success Factors ✅

1. Copilot-assigned gate/review bots executing green: 8 of 11 successes are non-agentic bot workflows completing cleanly on already Copilot-assigned branches — CGO, CWI, Ponytail Reviewer, Matt Pocock Skills Reviewer, PR Code Quality Reviewer, Stale Lock Files, PR Data Prefetch, Running Copilot Code Review.

   • Share of today's successes: 73%
   • Example: CGO and CWI both completed on copilot/fix-docs-links inside the same 41-minute window as the rest of that branch's gate sweep.

2. Sustained iterative work on one branch converts to real completions: copilot/fix-docs-links produced 9 of today's 11 successes (82%) from 20 total firings (45% success rate on that branch alone vs 4% elsewhere).

   • Success rate on this branch: 45% (9/20)
   • Example: 3 "Addressing comment on PR" agentic runs on this branch's PR (Fix broken gallery links in multi-device docs testing #57082) and its siblings (Implement exploration-error trajectory grader #57087, Fix ESLint GitHub API throw correlation across retry callbacks #57089) all succeeded, the longest running 20.1 minutes of genuine work.

3. Agentic comment-addressing runs succeed at 100% today: all 3 "Addressing comment on PR #NNNNN" runs succeeded (PR Fix broken gallery links in multi-device docs testing #57082: 20.1m, Fix ESLint GitHub API throw correlation across retry callbacks #57089: 15.3m, Implement exploration-error trajectory grader #57087: 9.8m) — these are real iterative-agent executions, not 0-duration stubs.

   • Success rate: 3/3 (100%)

Failure Signals ⚠️

1. Gate-sweep saturation dominates the denominator: 38/50 (76%) of runs are action_required 0-duration approval stubs, which suppresses the raw completion% independent of any agent's actual work quality.

   • Failure rate contribution: 76% of the sample never executes
   • Example: repeated Squad (13×) and Agentic Commands (13×) firings across the 5 branches, most at 0-duration.

2. One genuine execution failure: CJS failed on copilot/trajectory-grader-implement-exploration-error after 4.97 minutes of real work — the only branch today where sustained activity (9 firings) produced zero successes.

   • Failure rate on this branch: 0% success / 9 firings
   • Worth a manual look at that branch's CJS run given it's real (non-stub) failed work.

3. Narrow, bursty sample: all 50 runs land in a single 41-minute window across just 5 branches — today's 22% figure describes one snapshot, not a representative cross-section of agent quality; day-to-day swings of ±20pts (see chart 1) are largely which branches happened to push in this narrow capture window.

Prompt Quality Analysis 📝

Per-Prompt Breakdown

Not assessable this run. sessions-list.json carries only workflow run metadata (name, branch, timestamps, conclusion) — the actual task/prompt text given to each agent session is not present in this dataset, and conversation transcripts (which would carry user.message turns) are empty for the 46th+ consecutive day. This section has returned "unavailable" in every recorded snapshot back to 2026-08-22 and, per repo memory, considerably further — it is a standing, unresolved pipeline gap rather than a one-off miss.

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 5 open PRs (0%)
• Historical Baseline: 0.0% orphaned rate (30-day mean over 8 recorded days)
• Status: NORMAL (today's rate does not exceed baseline)

Escalation Candidate Details

Escalation Candidates

✅ No orphaned branches exceed the escalation threshold today.

All 5 open PRs (#57082, #56572, #56568, #56564, #56562) are Copilot-assigned. Only 1 workflow run was in-progress in the last 6 hours (this analysis run itself, on main), so no branch carries a live gate backlog right now.

CI Waste Estimate

• Orphaned gate-hours today: 0 — no escalation candidates, no orphaned CI capacity to recover.

Notable Observations

Loop Detection and Session Diagnostics

Loop Detection

• Not measurable — no conversation transcripts to inspect for repetitive turns.

Workflow Usage (proxy for "tool usage" — no per-agent tool-call data available)

• Most-fired workflows: Squad (13), Agentic Commands (13), Squad Implement Worker (3), PR Description Updater (3), Label Closed PRs (3)
• Completion by workflow type: gate/review bots (CGO, CWI, Ponytail Reviewer, Matt Pocock Skills Reviewer, PR Code Quality Reviewer, Stale Lock Files, PR Data Prefetch, Running Copilot Code Review) succeeded 8/8 times they appeared; core CI sweep workflows (Squad, Agentic Commands, Squad Implement Worker, Label Closed PRs, PR Description Updater) accounted for all 38 action_required stubs plus the 1 CJS failure.
• Missing tools: none reported — no session-level tool-request signal available in this dataset.

Context Issues

• Not measurable — no conversation transcripts available.

Experimental Analysis

Standard analysis only this run (30% experimental-strategy roll did not trigger). No experimental strategy this run — prior experimental runs (gate_footprint_signature, per_branch_gate_fanout, AWTC, branch_level_gate_bundle_concentration, failure_to_fix_latency, reviewer_bot_fan_out_synchronicity) remain the most recent novel methods tried; see repo memory session-analysis-strategies.json for full history.

Actionable Recommendations

For Users Writing Task Descriptions

Prompt-text examples cannot be produced honestly this run (no prompt content in the available metadata). Based on the metadata patterns instead:

1. Expect gate noise to dwarf agent signal: 76% of daily runs are 0-duration approval stubs. When judging whether an agent is "stuck," check the executed-session count (bottom panel of the duration chart) rather than the raw completion percentage.
2. Concentrate follow-up review on branches with high firing counts (today: fix-docs-links at 20 firings, eslint-factory-require-error-code-fix at 14) — these are where real iterative work and real risk of a stuck loop would show up first.

For System Improvements

1. Fix the conversation-log fetch pipeline: 46+ consecutive days with zero transcript data means loop detection, context-confusion detection, and prompt-quality scoring have been unavailable for the entire recorded history of this workflow. This is the single highest-value fix for this analysis to become more than CI/infra metadata.
   • Potential impact: High
2. Track "executed session rate" (non-zero duration) as a primary KPI alongside raw completion%: gate-stub saturation (76% today, 82–96% historically) swamps the completion-rate signal and makes day-to-day swings hard to interpret without manually separating stubs from real runs.
   • Potential impact: Medium

For Tool Development

1. Per-branch gate fan-out dashboard: today's analysis required ad hoc jq grouping to find that one branch drove 82% of successes. An automated per-branch firing/success breakdown would surface concentration and orphan-risk patterns without manual inspection each day.
   • Frequency of need: every recorded run (9/9 days so far)

Historical Trends and Statistical Summary

Trends Over Time

• Completion rate trend: oscillating 10%–42% over the 9 recorded days with no sustained direction (32→42→26→10→32→32→40→18→22); today is a partial rebound from 08-29's floor but stays below the 8-day trailing mean (~31.6%).
• Average duration trend: noisy in a 0.8–3.8 min range; today's 2.45 min is mid-pack.
• Orphan rate: flat 0.0% across all 8 prior recorded days plus today — consistently healthy, no signal of Copilot-assignment neglect.

Loop Detection:              not measurable (conversation logs unavailable)
Context Issues:              not measurable (conversation logs unavailable)
Tool Failures:                1 (CJS on trajectory-grader branch)

High-Quality Prompts:        not measurable (no prompt content in dataset)
Medium-Quality Prompts:      not measurable
Low-Quality Prompts:         not measurable

Next Steps

• Review recommendations with team
• Prioritize fixing the conversation-log fetch pipeline (46+ day outage) so future runs can do real behavioral analysis
• Take a manual look at the CJS failure on copilot/trajectory-grader-implement-exploration-error
• Consider adding "executed session rate" as a tracked KPI alongside raw completion%
• Schedule follow-up analysis tomorrow (standard daily cadence)

📈 Session Trends Analysis

Completion Patterns

Completion rate is bimodal and branch-driven rather than trending: today's 22% sits below the 8-day mean, and the top panel shows the "successful" (green) band has stayed in the 5–21 session range all 9 days while the red "failed/action_required" band absorbs the rest — a persistent gate-sweep floor, not a quality signal.

Duration & Efficiency

Median duration is flat at 0 minutes every single day because gate-stub runs (action_required, 0-duration) make up the majority of the sample; average duration and the executed-session count both swing independently of completion%, confirming that "how much real work ran" and "what fraction reports as complete" are two different signals that the raw completion metric conflates.
