npx skills add kochetkov-ma/claude-brewcode --skill text-optimizer
Optimizes text, prompts, and documentation for LLM token efficiency. Applies 52 research-backed rules across 8 categories: Claude behavior, token efficiency, structure, deduplication, reference integrity, perception, LLM comprehension, and aggressive lossy (deep only). Use when optimizing prompts, reducing tokens, compressing verbose docs, or improving LLM instruction quality.
npx skills add kochetkov-ma/claude-brewcode --skill text-optimizer
Plugin: kochetkov-ma/claude-brewcode
Reduces token count in prompts, docs, and agent instructions by 20–40% without losing meaning. Applies 52 research-backed rules across 8 categories: Claude behavior, token efficiency, structure, deduplication, reference integrity, perception, LLM comprehension, aggressive lossy (deep only).
Benefits: cheaper API calls · faster model responses · clearer LLM instructions · fewer hallucinations
Examples:
Skill text is written for LLM consumption and optimized for token efficiency.
REQUIRED: Read
references/rules-review.mdbefore ANY optimization. If file not found -> ERROR + STOP. Do not proceed without rules reference.
Parse $ARGUMENTS: -l/--light | -d/--deep | no flag -> medium (default).
| Mode | Flag | Scope |
|---|---|---|
| Light | -l, --light | Text cleanup only — structure, lists, flow untouched |
| Medium | (default) | Balanced restructuring — all standard transformations |
| Deep | -d, --deep | Max density — rephrase, merge, compress aggressively |
| Category | Rule IDs | Scope |
|---|---|---|
| Claude behavior | C.1-C.8 | Literal following, avoid "think", positive framing, match style, descriptive instructions, overengineering, avoid ALL-CAPS, prompt format |
| Token efficiency | T.1-T.8, T.10 | Tables, bullets, one-liners, inline code, abbreviations, filler, comma lists, arrows, strip whitespace |
| Structure | S.1-S.8 | XML tags, imperative, single source, context/motivation, blockquotes, progressive disclosure, consistent terminology, ref depth |
| Deduplication | D.1-D.6 | Exact/near/cross-format merge, emphasis cap <=2, cross-file SSOT, wrong-merge guard |
| Reference integrity | R.1-R.3 | Verify file paths, check URLs, linearize circular refs |
| Perception | P.1-P.6 | Examples near rules, hierarchy, bold keywords, standard symbols, instruction order, default over options |
| LLM Comprehension | L.1-L.8 | Critical info position, documents-first, conciseness, quote-first, add WHY, reiterate constraint, prompt repetition, preserve scope qualifiers |
| Aggressive lossy (deep only) | A.1-A.4 | Line fusion, low-value word drop, aggressive paraphrase, common-knowledge elision |
| ID | Rule | ID | Rule |
|---|---|---|---|
| C.1 | Literal instruction following | C.2 | Avoid "think" word |
| C.3 | Positive framing (do Y not don't X) | C.4 | Match prompt style to output |
| C.5 | Descriptive over emphatic instructions | C.6 | Overengineering prevention |
| T.1 | Tables over prose (multi-column) | T.2 | Bullets over numbered (~5-10%) |
| T.3 | One-liners for rules | T.4 | Inline code over blocks |
| T.5 | Standard abbreviations (tables only) | T.6 | Remove filler words |
| T.7 | Comma-separated inline lists | T.8 | Arrows for flow notation |
| S.1 | XML tags for sections | S.2 | Imperative form |
| S.3 | Single source of truth | S.4 | Add context/motivation |

| R.1 | Verify file paths | R.2 | Check URLs |
| R.3 | Linearize circular refs | P.1 | Examples near rules |
| P.2 | Hierarchy via headers (max 3-4) | P.3 | Bold for keywords (max 2-3/100 lines) |
| P.4 | Standard symbols (→ + / ✅❌⚠️) | ||
| S.7 | Consistent terminology | S.8 | One-level reference depth |
| P.5 | Instruction order (anchoring) | P.6 | Default over options |
| C.7 | Avoid ALL-CAPS emphasis (4.x) | C.8 | Prompt format → output format |
| T.10 | Strip whitespace from code | ||
| L.1 | Critical info at START or END | L.2 | Documents first, query last |
| L.3 | Explicitly request conciseness | L.4 | Quote-first grounding |
| L.5 | Add WHY to instructions | L.6 | Reiterate constraint at END |
| L.7 | Prompt repetition (non-reasoning) | L.8 | Preserve scope qualifiers |
| D.1 | Exact-duplicate merge | D.2 | Near-duplicate merge (keep specific) |
| D.3 | Cross-format duplicate | D.4 | Emphasis cap (<=2/doc, echo @ END) |
| D.5 | Cross-file dedup (SSOT + pointer) | D.6 | Wrong-merge guard |
| A.1 | Line fusion (loss-free merge) | A.2 | Low-value word drop (gate-neutral) |
| A.3 | Aggressive paraphrase (preserved) | A.4 | Common-knowledge elision (ledger) |
| Mode | Applies | Notes |
|---|---|---|
| Light | C.1-C.8, T.6, D.1, R.1-R.3, P.1-P.4, L.1-L.8 | Text cleanup only — no restructuring |
| Medium | All rules (C + T + S + D + R + P + L) | Balanced transformations |
| Deep | All rules (C + T + S + D + R + P + L) + A.1-A.4 (aggressive lossy) | Merge sections, max compression |
Content essence is untouchable at light/medium; small deliberate loss only at deep — explicitly reported. Dedup-merged facts count as preserved, never as loss.
| Mode | Semantic match target | Allowed loss |
|---|---|---|
| Light | 100% | None — wording cleanup only |
| Medium | 100% | None — self-check fact inventory, zero loss |
| Deep | >= 95% | Low-value connective detail; self-verify round required, warn with loss list if < 95% |
Runs during analysis, BEFORE compression:

| Single path | Process file directly |

-l file.md | Light mode — text cleanup only |
-d file.md | Deep mode — max compression |

| "Don't do X" framing | Less effective than "Do Y" (C.3) |
| Overengineer prompts | Opus 4.5 follows literally (C.6) |
| Overload single prompts | Divided attention, hallucinations (S.3) |
| Over-focus on wording | Structure > word choice (T.1) |
| Merge similar-looking facts blindly | Different scope/numbers/conditions = different facts (D.6) |
