# Send Compress to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### ⚠️ Important Limitations

This is SEMANTIC compression, not bit-perfect lossless.

L1-L2: Verified reconstruction, production-ready
L3-L4: Experimental, may lose subtle information
Never use for: Medical dosages, legal text, financial figures, safety-critical data

### The Validation Loop

1. Compress original O → compressed C
2. Extract anchors from O (entities, numbers, dates)
3. Reconstruct C → R (without seeing O)
4. Verify: anchors match + semantic diff
5. If mismatch → refine C with missing info
6. Repeat until validated (max 3 iterations)

Convergence = verified. No convergence after 3 rounds = level too aggressive.

### Compression Levels

LevelRatioReliabilityUse CaseL1~0.8x✅ HighProduction, human-readableL2~0.5x✅ GoodSystem prompts, repeated useL3~0.3x⚠️ ModerateExperimental, review outputL4~0.15x⚠️ LowResearch only, expect losses

### Anchor Checksum System

Before compression, extract critical facts:

[ANCHORS: 3 people, $42,000, 2024-03-15, "Project Alpha"]

Reconstruction MUST reproduce these exactly. If anchors mismatch → compression failed.

### Core Rules

Always validate — Never trust compression without reconstruction test
Use anchors — Extract numbers, names, dates before compressing
Cap at L2 for production — L3-L4 are experimental
Report confidence — Include iteration count and anchor match rate
Independent verification — Consider different model for reconstruction

### Cost-Benefit Reality

Each compression costs 3-4 LLM calls. Break-even calculation:

break_even_retrievals = compression_tokens / saved_tokens_per_use

Only cost-effective if: You'll retrieve the compressed content 6-8+ times.

For one-time use → just use the original text.

### Before Compressing

Content type is NOT safety-critical
 Target level chosen (L1-L2 recommended)
 Anchors identified (numbers, names, dates)
 ROI makes sense (multiple retrievals expected)
