no-jejune-comments

no-jejune-comments is a cursor rule for Cursor from briangmilnes/APAS-VERUS. It costs 0 tokens per session (296 once invoked), scanned A, original, MIT.

A documentation rule that removes comments which merely repeat a function's name, parameters, or types. Comments should explain non-obvious behavior instead.

In plain words
What is it for?
Use it when reviewing comments or writing documentation about complexity, algorithms, invariants, edge cases, or other details not visible in a function signature.
Why use it?
Repetitive comments make code longer without helping readers, while useful comments preserve important constraints and implementation details.

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-jejune-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 6d 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

No Jejune Comments

Do not add comments that merely restate what is already clear from the function's name, parameters, and types.

Bad Examples

/// Returns the size of the set.
fn size(&self) -> N { ... }

/// Checks if the element is in the set.
fn contains(&self, elem: &T) -> bool { ... }

/// Creates a new empty set.
fn empty() -> Self { ... }

These comments add no value—the function names already convey the meaning.

Good Examples

/// APAS: Work Θ(|v|), Span Θ(1)
fn from_vec(v: Vec<T>) -> Self { ... }

/// Uses parallel divide-and-conquer; falls back to sequential for n < 1000.
fn parallel_filter(items: Vec<T>, pred: F) -> Vec<T> { ... }

/// The result excludes self-loops even if present in the input.
fn neighbors(&self, v: &V) -> Set<V> { ... }

These comments tell you something non-obvious: complexity, implementation strategy, or edge case behavior.

Rule

A comment should pass this test: "Does this tell me something I couldn't infer from the signature alone?"

If not, omit it.

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.
