"Optimizes text, prompts, and documentation for LLM token efficiency. Applies 41 research-backed rules across 6 categories: Claude behavior, token efficiency, structure, reference integrity, perception, and LLM comprehension. Use when optimizing prompts, reducing tokens, compressing verbose docs, or improving LLM instruction quality."

Text Optimizer
Reduces token count in prompts, docs, and agent instructions by 20–40% without losing meaning.
Applies 41 research-backed rules across 6 categories: Claude behavior, token efficiency, structure, reference integrity, perception, LLM comprehension.
Benefits: cheaper API calls · faster model responses · clearer LLM instructions · fewer hallucinations
Examples:
/text-optimize prompt.md # single file, medium mode (default)
/text-optimize -d agents/ # deep mode — all .md files in directorySkill text is written for LLM consumption and optimized for token efficiency.
Text & File Optimizer
Step 0: Load Rules
REQUIRED: Read
references/rules-review.mdbefore ANY optimization.
If file not found -> ERROR + STOP. Do not proceed without rules reference.
Modes
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 |
Rule ID Quick Reference
| Category | Rule IDs | Scope |
|---|---|---|
| Claude behavior | C.1-C.6 | Literal following, avoid "think", positive framing, match style, descriptive instructions, overengineering |
| Token efficiency | T.1-T.8 | Tables, bullets, one-liners, inline code, abbreviations, filler, comma lists, arrows |
| Structure | S.1-S.8 | XML tags, imperative, single source, context/motivation, blockquotes, progressive disclosure, consistent terminology, ref depth |
| 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 |
ID-to-Rule Mapping
| 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 |
| S.5 | Blockquotes for critical | S.6 | Progressive disclosure |
| 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 |
Mode-to-Rules Mapping
| Mode | Applies | Notes |
|---|---|---|
| Light | C.1-C.6, T.6, R.1-R.3, P.1-P.4 | Text cleanup only — no restructuring |
| Medium | All rules (C + T + S + R + P) | Balanced transformations |
| Deep | All rules + aggressive rephrasing | Merge sections, max compression |

Execution Flow
- Read
references/rules-review.md— load all optimization rules - Read target file(s)
- Analyze: identify type (prompt, docs, agent, skill), note critical info and cross-references
- Apply rules by mode (see Mode-to-Rules Mapping)
- Edit file with optimized content
- Generate optimization report
Quality Checklist
Before
- Read entire text
- Identify type (prompt, docs, agent, skill)
- Note critical info and cross-references
During — Apply by Mode
| Check | Light | Med | Deep |
|---|---|---|---|
| C.1-C.6 (Claude behavior) | Yes | Yes | Yes |
| T.6 (filler removal) | Yes | Yes | Yes |
| T.1-T.5, T.7-T.8 (token compression) | - | Yes | Yes |
| S.1-S.8 (structure/clarity) | - | Yes | Yes |
| R.1-R.3 (reference integrity) | Yes | Yes | Yes |
| P.1-P.4 (LLM perception) | Yes | Yes | Yes |
| Aggressive rephrasing | - | - | Yes |
| No information loss | Yes | Yes | Yes |
After
- All facts preserved
- Logic consistent
- References valid (R.1-R.3)
- Tokens reduced

| Avoid | Why |
|---|---|
| Remove all examples | Hurts generalization (P.1) |
| Over-abbreviate | Reduces readability (T.5 caveat) |
| Generic compression | Domain terms matter |
| Over-aggressive language | Opus 4.5 overtriggers (C.5) |
| Flatten hierarchy | Loses structure (P.2) |
| "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) |
