## 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

### JSON Modifier

A utility for modifying JSON files using RFC 6902 JSON Patch format.
Supports precise additions, removals, replacements, moves, copies, and tests.

### Usage

# Modify a file in place
node skills/json-modifier/index.js --file path/to/config.json --patch '[{"op": "replace", "path": "/key", "value": "new_value"}]'

# Modify and save to a new file
node skills/json-modifier/index.js --file input.json --patch '[...]' --out output.json

# Use a patch file
node skills/json-modifier/index.js --file input.json --patch-file patches/update.json

### Patch Format (RFC 6902)

The patch must be a JSON array of operation objects.

### Examples

Replace a value:

[
  { "op": "replace", "path": "/version", "value": "2.0.0" }
]

Add a new key:

[
  { "op": "add", "path": "/features/new_feature", "value": true }
]

Remove a key:

[
  { "op": "remove", "path": "/deprecated_key" }
]

Append to an array:

[
  { "op": "add", "path": "/list/-", "value": "item" }
]

### Safety

Validates patch against document before applying.
Atomic write (writes to temporary file, then renames).
Preserves indentation (default: 2 spaces).
