fp-minify

fp-minify is a skill for Claude Code from SlashyIsTaken/fp-pluginplaza. It costs 209 tokens per session (1,442 once invoked), scanned A, original, MIT.

A coding mode that keeps comments short and limited to information the code cannot show, such as reasons, units, limits, or unusual constraints.

In plain words
What is it for?
Use it when asking an AI to write or tidy code and you want concise inline comments, with a one-line limit and a way to control comment density.
Why use it?
It prevents generated code from becoming cluttered with comments that merely repeat what the code already says. It also keeps longer explanations out of the code when they belong in project history.

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

fp-minify 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

fp-minify

Model-written code is often excellent but over-commented — inline essays that restate what the code plainly does, or paragraph-long backstories that belong in a commit message. fp-minify sets a prior so comments earn their place: it keeps the ones that carry real information and cuts or compresses the rest, without ever changing what the code does.

Persistence

ACTIVE while on. Default: tidy — installing the plugin is the opt-in to concise comments. Off via /fp-minify:mode off or "stop fp-minify". Switch by typing fp-minify new / fp-minify tidy / fp-minify off (the plugin's hook applies it instantly, before the model replies).

When a comment earns its place

A comment is justified only when it carries what the code cannot. Two cases:

  • Why, not what. The reason for something non-obvious, surprising, or deliberately odd — so a later reader doesn't "fix" it back. The code already says what it does; a comment that restates that is noise.
  • Meaning a name can't hold. Config values, magic numbers, units, ranges, invariants, constraints — where the identifier alone can't tell you what's legal or why this number.

One line, hard

An earned comment is a single self-contained line. Not "one line by default", not "one line unless the reasoning needs room". A cap, with no judgment call to negotiate past.

The hardness is the point, so don't soften it back into a default. A rule that allows expansion "when the reasoning truly needs the room" never binds, because the model writes the comment minutes after working the problem out and always believes the room is needed. A subjective ceiling is no ceiling.

When a why won't fit on one line, you have two moves and neither is a paragraph:

  1. Split it. Anchor a one-liner at each thing it actually explains, rather than one block at the top explaining four of them.
  2. Cut to what the reader must have, and send the rest to the commit message.

Multi-line comments happen only when you explicitly ask for one.
