formatter-off

A command for checking Java code-generator files for formatting damage in blocks that build strings by joining source-code fragments. It adds formatter guards and puts newline-terminated fragments on one source line when needed.

In plain words
What is it for?
Scanning Java generators, repairing missing @formatter:off and @formatter:on markers, and reporting the changes made.
Why use it?
Automatic formatting can change generated source text or break its intended layout; this check identifies and fixes those violations.

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

formatter-off 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

Use the code-generation skill to understand the formatting conventions.

Scan all Java code generator files for string concatenation blocks containing \n that are missing // @formatter:off / // @formatter:on guards.

For each violation found, apply the fix procedure from the skill: wrap in formatter guards and collapse each \n-terminated segment onto a single Java source line.

Report what was fixed when done.

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.
