no-debug-logging

A rule that keeps temporary debugging output out of committed code. Debug output includes statements such as console.log, print, and debugger.

In plain words
What is it for?
Cleaning up temporary diagnostics before review or handoff, while preserving structured logs that the project deliberately uses.
Why use it?
It prevents investigation leftovers from cluttering logs or exposing information in production. Intentional messages should use the project's existing logging system.

Token cost

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.

Security

Grade A, and why

no-debug-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 yesterday.

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

No debug logging left behind (reflex)

  • Don't commit console.log/console.debug, print, dbg!, fmt.Println debug spew, or debugger; statements added while investigating.
  • Use the project's existing logger/abstraction for intentional, structured logging — match what the surrounding code already uses; don't introduce a new logging mechanism unasked.
  • Temporary diagnostics are fine while iterating, but remove them before self-verify/handoff.

This is a baseline. If the repo has a specific logger convention, encode it as a specialized, glob-scoped rule that takes priority over this one.

Changes

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.
