# Go CLI Cobra Code Review > Review pull requests for a Go CLI built with Cobra, especially Harvx-style repos. Use for full PR reviews that require strict Blocking vs Non-blocking findings, explicit CLI contract checks, Go/Cobra engineering checks, concrete verification steps, and path:line actionable feedback.

Use this review format exactly. # PR Review Summary - What this PR changes (1 to 3 bullets) - Risk level: Low / Medium / High (one sentence why) - Recommendation: Approve / Request changes / Comment-only # Blocking (must fix before merge) For each item, use: - **Issue:** - **Location:** - **Why it matters:** - **Suggestion:** - **How to verify:** Only include truly blocking issues: - Incorrect behavior, data loss, security vulnerabilities - Breaking CLI contracts - Unstable machine output or unannounced JSON/schema changes - Wrong stdout/stderr split that breaks piping and automation - Inconsistent or wrong exit-code behavior - Panics, nil dereference risk, race conditions, deadlocks - Missing critical tests for high-risk changes - CI-breaking issues (`gofmt`, `go vet`, failing tests, broken build) If any Blocking items exist, recommendation must be `Request changes`. # Non-blocking (should fix, not required for merge) Use the same item format as Blocking. Examples: - Readability and maintainability improvements - Small UX improvements - Non-critical extra tests - Minor performance improvements - Documentation clarity improvements If there are no blocking findings, explicitly say: `No blocking findings.` # CLI/UX Contract Checks (Go CLI) Answer each as `Pass`, `Fail`, or `Unknown` with one short justification: - Help text updated (`Short`, `Long`, `Example`) where behavior changed - Flags are consistent and discoverable; naming is not confusing - Stdout is clean for piping; user-facing errors go to stderr - Exit codes are consistent with command outcomes and documented if user-visible - Default output is human-friendly; machine mode exists when needed (`--json` or equivalent) - Output is deterministic (stable ordering) for scripts and golden tests - Backward compatibility preserved, or breaking change clearly communicated # Go/Cobra Engineering Checks Answer each as `Pass`, `Fail`, or `Unknown`: - `gofmt` applied to touched Go files - `RunE` used when command execution can fail; errors are propagated - Business logic is not unnecessarily trapped inside `cmd/` - Errors wrap context and preserve root cause (`fmt.Errorf("...: %w", err)`) - Mutable global state is avoided; dependencies are injected cleanly - Tests added or updated for changed behavior and edge cases - No hidden network calls in completions, help, startup, or hot paths - Logging/diagnostics do not pollute stdout # Harvx Project-Specific Checks Answer each as `Pass`, `Fail`, or `Unknown`: - Follows `AGENTS.md` conventions for architecture, testing, and error handling - Uses expected verification commands: - `go build ./cmd/harvx/` - `go vet ./...` - `go test ./...` - Exit code contract respected (`0` success, `1` error, `2` partial success) - Output ordering remains deterministic for reproducible artifacts - Uses `slog` for diagnostics; avoids ad-hoc debug prints in production code - High-risk areas have focused checks/tests: - Discovery/filtering - Token budgeting - Redaction/security - Compression fallback behavior - Output rendering stability # Suggested Tests / Verification Steps Provide a short concrete checklist: - `go test ./...` - `go vet ./...` - `go build ./cmd/harvx/` - 3 to 8 manual CLI commands relevant to the PR - If output changed, include pipe tests (for example `| jq`, `| grep`) and golden test update guidance # Patch Suggestions (optional) If small, safe, targeted snippets help, include them. - Keep snippets minimal and directly actionable. - Avoid large refactors unless the PR is already a refactor. # Unknowns / Missing Context If context is missing: - Mark affected checks/items as `Unknown`. - Ask only for the exact missing artifact needed (for example: failing command output, specific file, expected JSON contract). - Do not assume details that are not present. # No-Findings Rule If no issues are found: - State `No blocking findings.` - State whether recommendation is `Approve` or `Comment-only`. - List residual risks or testing gaps briefly. # Tone Rules - Be direct and specific. - Use "Do X because Y; verify by Z." - Avoid generic advice. - Every finding must reference a concrete behavior and a code location (`path:line`) when available. # Normative Sources for "Must" Claims When making normative claims, cite one of: - https://go.dev/doc/effective_go - https://go.dev/wiki/CodeReviewComments - https://go.dev/blog/gofmt - https://clig.dev/ - https://cobra.dev/docs/ --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/abdelazizmoustafa10m) — claim your Tome and manage your conversions.
