Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00224 |
| Opus 5 | $0.00000 | $0.00112 |
| Sonnet 5 | $0.00000 | $0.00045 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
104-console-logging 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 4d 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.
What it actually says
Console Logging Best Practices
Description
When adding console logs for debugging, always use JSON.stringify with pretty print (spacing) when logging objects. This makes logs easier to read and copy/paste, especially for complex or nested data.
Guidelines
- Use
console.log(JSON.stringify(obj, null, 2))when logging objects or arrays. - Avoid logging raw objects directly (e.g.,
console.log(obj)), as this can result in collapsed or hard-to-read output in some environments. - For single values or strings, regular
console.logis fine. - Remove or comment out debugging logs before committing production code, unless logs are intentionally permanent.
Example
// ✅ Good:
console.log(JSON.stringify(userProfile, null, 2))
// ❌ Bad:
console.log(userProfile)
Rationale
- Pretty-printed JSON is easier to scan, debug, and copy/paste into tools or documentation.
- Reduces confusion when sharing logs with teammates or in issues.
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.

104-console-logging is a cursor rule published in the GitHub repository johnpolacek/vibecode.party.starter (27 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 224 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
