retro

<objective> Post-run retrospective analysis. After `/research:run` completes, reads `.experiments/state/<run-id>/experiments.jsonl`, computes statistical significance, detects dead iterations, flags suspicious metric jumps, generates learning summary with next-hypothesis queue. NOT for: running experiments (use `/research:run`); designing experiments (use `/research:plan`); validating methodology (use `/research:judge`); verifying paper implementation (use `/research:verify`); comparing runs from different programs/goals — `--compare` valid only for same-program, same-metric runs. Read-only — never modifies code, commits, or experiment state. </objective> <workflow> ## Agent Resolution **Agent resolution**: load and follow the protocol below. Contains: foundry check + fallback table. `research:scientist` in same plugin — no fallback needed if research plugin installed. ```bash _RESEARCH_SHARED=$(python "${CLAUDE_PLUGIN_ROOT:-plugins/research}/bin/resolve_shared.py" 2>/dev/null) # timeout: 5000 [ -z "$_RESEARCH_SHARED" ] && { echo "! Plugin path resolution failed — ensure research plugin installed and CLAUDE_PLUGIN_ROOT set, or invoke /research:retro from project root."; exit 1; } cat "$_RESEARCH_SHARED/agent-resolution.md" ``` ## Retro Mode (Steps T1–T7) Triggered by `retro`, `retro <run-id>`, or `retro <run-id> --compare <run-id-2>`. **Defaults**: `--threshold 0.001`, `--alpha 0.05`. **Unsupported flag check**: load and follow the protocol below.
