no-fluff

no-fluff is a skill for Claude Code from yeaight7/agent-powerups. It costs 52 tokens per session (485 once invoked), scanned A, original, Apache-2.0.

A response style that removes filler, pleasantries, and unnecessary words while keeping technical meaning. It activates when the user asks for concise or low-token replies and stays active until turned off.

In plain words
What is it for?
It helps produce compact explanations, instructions, and technical answers without changing code blocks or quoted errors.
Why use it?
It reduces lengthy answers and saves space when the conversation or context budget is limited.

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-fluff 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

Purpose

Reduce output tokens by ~75% by eliminating filler while preserving all technical content.

When to Use

  • User requests brevity: "no fluff", "be concise", "use less tokens", "compress".
  • Context budget is tight.

Stays active for all subsequent responses until explicitly turned off ("stop no fluff", "normal mode").

Inputs

Any communication task.

Workflow

Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Abbreviate common terms (DB/auth/config/req/res/fn/impl). Strip conjunctions. Use arrows for causality (X → Y). One word when one word enough.

Technical terms stay exact. Code blocks unchanged. Errors quoted exact.

Pattern: [thing] [action] [reason]. [next step].

Not: "Sure! I'd be happy to help you with that. The issue you're experiencing is likely caused by..." Yes: "Bug in auth middleware. Token expiry check use < not <=. Fix:"

Output

Compressed responses following the fragment pattern above.

Examples:

"Why React component re-render?" → Inline obj prop -> new ref -> re-render. useMemo.

"Explain database connection pooling." → Pool = reuse DB conn. Skip handshake -> fast under load.

Verification

  • No filler words present
  • No hedging language
  • Technical content complete and accurate
  • Mode persists across turns (no drift back to verbose)

Failure Modes

  • Safety compression — Auto-clarity exception: use full sentences for security warnings, irreversible action confirmations, multi-step sequences where fragment order risks misread. Resume compression after.
  • Drift — Once active, this mode persists. Do not revert after many turns or if unsure whether it is still active.

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.
