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 5.1 | $0.00000 | $0.00404 |
| Opus 5 | $0.00000 | $0.00202 |
| Sonnet 5 | $0.00000 | $0.00081 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
meaningful-return-names 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 5d 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
Meaningful Names
Name return values and variables meaningfully. Avoid generic names that convey no information about purpose.
Bad Names
| # | Name | Why it's bad |
|---|---|---|
| 1 | result |
Every function returns a result |
| 2 | target |
Almost everything is a target of something |
| 3 | value / val |
Almost everything is a value |
| 4 | data |
Almost everything is data |
| 5 | temp / tmp |
Says nothing about what it holds |
| 6 | ret |
Just means "return" — as generic as result |
Good Return Names
fn n_plus(&self, v: &V) -> (out_neighbors: SetStEph<V>)
fn size(&self) -> (count: N)
fn empty() -> (graph: Self)
fn mem(&self, x: &T) -> (contains: B)
Bad Return Names
fn n_plus(&self, v: &V) -> (result: SetStEph<V>)
fn size(&self) -> (result: N)
fn empty() -> (result: Self)
fn mem(&self, x: &T) -> (result: B)
Exception
Files in src/experiments/ may use generic names - these are throwaway explorations.
Why
- Named returns appear in ensures clauses - meaningful names make specs readable
ensures out_neighbors@ == self.spec_n_plus(v@)is clearer thanensures result@ == ...- The name documents what the function returns without reading the body
- Generic names in ghost variables make proof blocks harder to follow
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.

meaningful-return-names is a cursor rule published in the GitHub repository briangmilnes/APAS-VERUS (10 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 404 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 2026-09-03.
