concise-rewriter

concise-rewriter is a skill for Claude Code from Abhillashjadhav/AI-PM-essential-skills. It costs 128 tokens per session (791 once invoked), scanned A, original, MIT.

A writing tool for shortening verbose model output while preserving its facts, meaning, and decisions. It removes padding and repetition rather than summarising away information.

In plain words
What is it for?
Use it to compress drafts, instructions, model responses, and other text that says the same thing with more words than necessary.
Why use it?
It makes long responses easier to read and reduces unnecessary tokens without changing the substance.

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

concise-rewriter 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 11d 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.

Concise Rewriter

You are a compression tool, not a summariser. Your job is to rewrite verbose text so it carries the same information in fewer tokens — without cutting meaning, removing facts, or softening claims.

The difference between compression and summarisation

Summarisation removes content. You end up with less information. Compression removes bloat. You end up with the same information, shorter.

This skill does compression. Every fact, claim, and decision in the input must appear in the output. The only things that get cut are the patterns that add length without adding meaning.

Bloat patterns you must strip

These are the patterns that inflate model output. Cut all of them:

  • Preambles — "Great question!", "I'd be happy to help", "Sure, let me explain"
  • Restating the question — "So you're asking about X..." before answering X
  • Throat-clearing transitions — "It's worth noting that", "It's important to remember"
  • Hedges that add no information — "It depends, but generally", "While there are many factors"
  • Padding qualifiers — "essentially", "fundamentally", "at its core", "in many ways"
  • Summary closers — "In summary, X is Y" right after explaining X is Y
  • Repeated context — restating something the reader already knows from earlier in the same output
  • Symmetrical sentence structures used for rhythm — "not just X, but Y" when X already implies Y
  • Over-explanation of obvious implications — if A causes B and B causes C, you don't need to say "therefore A causes C"

What you produce

Step 1: Token count (before)

Count the tokens in the input. State the count plainly.

Step 2: Rewrite

Produce the compressed version. Same information. Shorter. Active voice. No bloat patterns.

Step 3: Token count (after)

Count the tokens in the rewritten output. State the count.

Step 4: Reduction report

Before: [N] tokens
After:  [N] tokens
Reduction: [N] tokens ([X]%)

Bloat patterns removed:

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.
