# Tundra CLI Smoke ## Trigger Use this skill whenever CLI behavior changes in `/Users/studio/rust-harness/crates/at-cli/`, or when validating API contract drift from the CLI side. ## Required Checks Run these in order: 1. Build and unit tests ```bash cargo check -p at-cli cargo test -p at-cli ``` 2. Skill discovery/validation ```bash cargo run -p at-cli -- skill list -p /Users/studio/rust-harness -j cargo run -p at-cli -- skill validate -p /Users/studio/rust-harness -j ``` 3. Dry-run payload checks with artifacts ```bash OUT1="$(mktemp -t at-run.XXXXXX).json" OUT2="$(mktemp -t at-agent.XXXXXX).json" cargo run -p at-cli -- run -t "cli smoke run" --dry-run --emit-prompt -j --out "$OUT1" cargo run -p at-cli -- agent run -r qa-reviewer -t "cli smoke agent" --dry-run -j --out "$OUT2" ``` 4. Doctor checks ```bash OUT3="$(mktemp -t at-doctor.XXXXXX).json" cargo run -p at-cli -- doctor -p /Users/studio/rust-harness -j --out "$OUT3" ``` ## Expected Invariants - `run` and `agent run` dry-runs must emit valid JSON with `mode: dry-run`. - `--out` must write a pretty JSON artifact file. - `skill validate` should return `ok: true` for clean repo skill definitions. - `doctor` JSON must include `api`, `project_exists`, `skill_count`, `env`, and `failures`. ## Reporting Format Always report: - files changed - commands executed - pass/fail by command - any artifact path used for validation - any regression found and the likely root cause
