Problem
Per-session performance telemetry (events.jsonl, tool-call timing, payload sizes, validation timing, context-size, model-switch events) required by this optimizer's Phase 2 analysis was completely absent for all 50 Copilot sessions in the last-14-day window, blocking detection of slow tool calls, oversized responses, late validation failures, oversized instruction payloads, and prompt drift.
Evidence
- Analysis window: 2026-08-10 to 2026-08-24 (last 14 days)
- Sessions enumerated: 50 (from
/tmp/gh-aw/agent/session-data/sessions-list.json)
/tmp/gh-aw/agent/session-data/logs/ contained 0 files — no *-conversation.txt, no events.jsonl, and no fallback logs for any of the 50 in-scope sessions- The
shared/copilot-session-data-fetch.md import that is supposed to populate this directory ran without error but produced an empty logs/ folder, while the parallel shared/copilot-pr-data-fetch.md import correctly populated /tmp/gh-aw/agent/pr-data/copilot-prs.json with 1000 records
- This is a systemic gap: every run of this optimizer workflow with the current data-fetch configuration will silently skip Phase 2 (tool latency, payload size, validation timing, context size, model-switching, prompt-drift analysis) because there is no source data to analyze
Proposed Change
Investigate why shared/copilot-session-data-fetch.md is not writing conversation/event logs to /tmp/gh-aw/agent/session-data/logs/ (e.g., check the session IDs/branch filter used to fetch logs, confirm the correct artifact or API endpoint is targeted, and confirm write permissions/paths match what this workflow expects). Add an explicit non-fatal warning step immediately after the fetch that fails loudly (or posts a missing_data signal) when the logs directory is empty, so future runs surface the gap instead of silently producing partial reports.
Expected Impact
- Restores Phase 2 performance analysis (tool latency, payload size, validation timing, context size, model-switching, prompt drift) for all future runs of this optimizer, which is currently 100% blocked.
- Prevents future optimizer runs from silently under-reporting findings without any indication that a whole analysis phase was skipped.
Notes
- Distinct root cause category: tool payload/latency optimization infrastructure (session telemetry availability), which blocks the underlying analysis this recommendation depends on
- Data quality caveat: this issue itself is evidence of the gap — no session-level timing/context/drift metrics could be computed this run because the source data was missing.
