What: Add a GSTACK_AUTO_UPGRADE=1 env var or ~/.gstack/config option that skips the AskUserQuestion prompt and upgrades automatically when a new version is detected.
Why: Power users and CI environments may want zero-friction upgrades without being asked every time.
Context: The current upgrade system (v0.3.4) always prompts via AskUserQuestion. This TODO adds an opt-in bypass. Implementation is ~10 lines in the preamble instructions: check for the env var/config before calling AskUserQuestion, and if set, go straight to the upgrade flow. Depends on the full upgrade system being stable first — wait for user feedback on the prompt-based flow before adding this.
Effort: S (small) Priority: P3 (nice-to-have, revisit after adoption data)
What: Run eval suite in CI, upload result JSON as artifact, post summary comment on PR.
Why: Currently evals only run locally. CI integration would catch quality regressions before merge and provide a persistent record of eval results per PR.
Context: Requires ANTHROPIC_API_KEY in CI secrets. Cost is ~$4/run. The eval persistence system (v0.3.6) writes JSON to ~/.gstack-dev/evals/ — CI would upload these as GitHub Actions artifacts and use eval:compare to post a delta comment on the PR.
Depends on: Eval persistence shipping (v0.3.6). Effort: M (medium) Priority: P2
What: bun run eval:dashboard serves local HTML with charts: cost trending, detection rate over time, pass/fail history.
Why: The CLI tools (eval:list, eval:compare, eval:summary) are good for quick checks but visual charts are better for spotting trends over many runs.
Context: Reads the same ~/.gstack-dev/evals/*.json files. ~200 lines HTML + chart.js code served via a simple Bun HTTP server. No external dependencies beyond what's already installed.
Depends on: Eval persistence + eval:list shipping (v0.3.6). Effort: M (medium) Priority: P3 (nice-to-have, revisit after eval system sees regular use)
