Terminal Stylist Analysis: Console Output Patterns (pkg/, Go non-tests)

Scope and method

• Analyzed only .go files under pkg/.
• Excluded all _test.go files.
• Searched for: fmt.Print*, fmt.Fprint*, console.*, lipgloss.*, and huh.* usages.

Summary

• The codebase already centralizes most user-facing styling through pkg/console and pkg/styles.
• Raw fmt.Fprint* usage is widespread in CLI/rendering code, but in many places it is used as a transport to print already-formatted console strings, which is acceptable.
• Lipgloss usage is concentrated and generally well-structured (pkg/styles/theme.go, pkg/styles/huh_theme.go, pkg/console/*).
• Huh usage is concentrated in interactive flows and wrapper utilities; structure appears consistent and reusable via pkg/console helpers.

Good patterns observed

• pkg/styles/theme.go: defines a shared style system with reusable style vars and centralized color tokens.
• pkg/styles/huh_theme.go: maps style tokens into Huh theme integration, avoiding one-off form styling.
• pkg/console/console.go and pkg/console/render.go: console formatting and table/list rendering are abstracted behind package helpers.
• CLI files commonly print messages with helpers like console.FormatInfoMessage, console.FormatWarningMessage, and console.RenderTable before writing to stderr/stdout.

Files with strongest direct-output concentration

High fmt.*print* usage (potential review hotspots for consistency):

• pkg/cli/audit_diff_render.go
• pkg/cli/audit_cross_run_render.go
• pkg/workflow/drive_memory.go
• pkg/cli/mcp_inspect_mcp.go
• pkg/workflow/cache_memory.go
• pkg/cli/graders_operational_value_report_render.go
• pkg/cli/logs_metrics.go
• pkg/cli/trial_repository.go
• pkg/cli/audit_report_render.go
• pkg/cli/shell_completion.go

Console formatter consistency findings

• Mostly consistent: many print calls emit strings returned by console.* helpers.
• Needs selective cleanup: some direct literal prints (fmt.Fprintf(..., "...\n")) coexist next to formatter usage in the same command handlers.
• Recommendation: for user-facing status lines, route all messaging through console.Format* helpers; reserve raw fmt for machine-oriented/plain output paths only.

Error-message formatting

• Positive: warning/error helpers are used in many paths (console.FormatWarningMessage*, etc.).
• Improvement opportunity: standardize whether errors always include an icon/prefix and whether they always go to stderr through a single helper pattern.

Lipgloss analysis

• Good:
  • Centralized style declarations avoid style drift.
  • Use of adaptive/background-aware patterns is present in styles layer.
  • Border and semantic text styles exist as reusable primitives.
• Opportunities:
  • Ensure any remaining hardcoded visual formatting in CLI renderers moves into pkg/styles/pkg/console helpers.
  • For tabular views, prefer shared table rendering paths to avoid per-command layout divergence.
  • Validate non-TTY behavior in renderers to avoid noisy ANSI in redirected output.

Huh analysis

• Good:
  • Interactive flows use huh primarily through reusable wrappers in pkg/console and interactive command modules.
  • Theming integration exists (pkg/styles/huh_theme.go), supporting consistent UX.
• Opportunities:
  • Confirm all interactive prompts consistently surface validation errors using shared console formatting.
  • Verify accessibility mode handling is uniformly applied in prompt wrappers, not only in selected call sites.

Anti-patterns to watch

• Mixing raw fmt.Fprintf(os.Stderr, "message") with console.Format* in same function.
• Ad-hoc list/table line formatting where a console.RenderTable or list helper is available.
• Stringly-typed severity prefixes embedded directly in literals instead of helper functions.

Prioritized recommendations

1. Create a short output-style checklist in developer docs: when to use console.Format*, when raw fmt is allowed.
2. Refactor top print-heavy renderer files to remove remaining literal status/error lines.
3. Add/expand small helper wrappers for frequent output shapes (headers, key-value blocks, summaries).
4. Add focused tests for non-TTY rendering behavior in pkg/console paths (if missing).
5. Keep Lipgloss and Huh customization centralized; avoid command-level style construction except for truly local needs.

Example guidance

• Prefer:
  • fmt.Fprintln(os.Stderr, console.FormatWarningMessage("...") )
  • fmt.Fprint(os.Stderr, console.RenderTable(tableConfig))
• Avoid (for user-facing status/errors):
  • fmt.Fprintf(os.Stderr, "Warning: ...\n")
  • manual ANSI/color escape composition in command files.

Conclusion

The repository already has a solid console architecture with console + styles abstraction and Charmbracelet integration. The primary improvement path is consistency hardening in print-heavy CLI renderers: reduce raw literal prints, standardize severity formatting, and keep table/list output routed through shared helpers.
