What is coding.use_single_return?

A code-cleanup procedure that changes functions so they normally have one return statement, while preserving allowed early exits from functions that return no value.

Use it on selected files, then run their unit tests to check that the cleanup did not alter results.

It applies a consistent function structure without intentionally changing behavior.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00011	$0.00144
Opus 5.5	$0.00004	$0.00058
Sonnet 5.5	$0.00002	$0.00029

Security

Grade A, and why

coding.use_single_return 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

I will pass you one or more files <FILES>

Goal

Go through each function and make sure it has a single return statement
For functions returning None, keep the return statements that exit early

Conventions

Do not change the behavior of the code in any way
Follow the rules in .claude/skills/coding.rules.md

Verification

Confirm each function has a single return statement (except early exits in functions returning None)
Run the file's unit tests to confirm behavior is unchanged

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.
