What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00028 | $0.00814 |
| Opus 5.5 | $0.00011 | $0.00326 |
| Sonnet 5.5 | $0.00006 | $0.00163 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade A, and why
vf-cli-output scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Veryfront CLI Output Patterns
Overview
Veryfront CLI follows a strict style guide for terminal output. Human-first by default, machine output via --json.
Core principle: Simple, empathetic, consistent. Red is only for errors.
Output Helpers
import { brand, dim, error, muted, success, warning } from "#cli/ui";
// Success
console.log(" " + success("✓") + " Done");
// Error
console.log(" " + error("✗") + " Failed to compile");
console.log(" " + dim("Try running: deno task typecheck"));
// Active/Info
console.log(" " + brand("●") + " Building project...");
// Inactive
console.log(" " + muted("○") + " Waiting");
// Warning
console.log(" " + warning("!") + " This option is deprecated");
Formatting Rules
| Rule | Example |
|---|---|
| 2-space indent for all content | " ✓ Done" |
| Blank line between logical sections | Separate status groups |
| Red only for errors | Never red for warnings or info |
| Yellow for warnings | warning("!") |
| No emoji in standard output | Use text icons: ✓ ✗ ● ○ ! |
Respect NO_COLOR env var |
Colors auto-disable |
Icons
| Icon | Meaning | Helper |
|---|---|---|
✓ |
Success/complete | success() |
✗ |
Error/failure | error() |
● |
Active/running | brand() |
○ |
Inactive/pending | muted() |
! |
Warning/caution | warning() |
Error Messages
Errors must be empathetic and actionable:
// Good: specific, actionable
console.log(" " + error("✗") + " Config file not found");
console.log(" " + dim("Expected: veryfront.config.ts in project root"));
console.log(" " + dim("Run: veryfront init to create one"));
// Bad: vague, unhelpful
console.log("Error: config error");
Exit Codes
| Code | Meaning |
|---|---|
0 |
Success |
1 |
General error |
2 |
Invalid usage (wrong args, missing required) |
130 |
Interrupted (Ctrl+C) |
Machine Output (--json)
// Success
console.log(JSON.stringify({
success: true,
data: { url: "https://app.veryfront.com", projectId: "abc" }
}));
// Error
console.log(JSON.stringify({
success: false,
error: { code: "PROJECT_NOT_FOUND", message: "No project found in current directory" }
}));
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
