no-comments

A project rule for keeping code comments minimal and useful. Comments should explain purpose, unusual reasoning, complex logic, side effects, or interfaces rather than restating each line.

In plain words
What is it for?
Deciding when to add method, class, interface, algorithm, API, or TODO comments in the codebase.
Why use it?
It reduces comments that become outdated or add maintenance work while still documenting information the code cannot show clearly.

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.

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-comments 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 2d 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

Code Documentation Guidelines

Commenting Philosophy

This project follows a minimalist approach to code comments, focusing on clarity through well-structured, self-documenting code.

Comment Guidelines

  1. Documentation Comments Only: Add comments only when they provide documentation value. The code itself should be clear enough to understand without excessive comments.

  2. No Line-by-Line Comments: Avoid explaining each line of code with a comment. This creates maintenance overhead and often becomes outdated.

  3. Method-Level Documentation: Place concise documentation comments above methods/functions to explain:

    • Purpose of the method
    • Complex logic that may not be immediately obvious
    • Any important side effects
  4. Class-Level Documentation: Document classes with a brief description of their purpose and responsibility.

  5. Interface Documentation: Document interfaces with clear descriptions of their intent and contract.

When to Use Comments

Good Use of Comments:

  • Explaining "why" something is done a certain way
  • Documenting complex algorithms
  • Flagging future enhancements (TODO comments)
  • Documenting API interfaces

Avoid Comments For:

  • Explaining obvious code
  • Duplicating what the code already clearly states
  • Commenting out unused code (delete it instead)
  • Line-by-line explanations

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.

no-comments is a cursor rule published in the GitHub repository BrainDAO/adk-ts (119 stars, last pushed 2mo ago), licensed MIT. It adds 278 tokens to every session, about $0.0014 per session on Opus 5. 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.
