  JSON flat view, schema inference, and edit tool.

  ⚠️ CRITICAL: ALWAYS use jstool for JSON files - NEVER use read/edit/cat on *.json!

  Use when the user provides JSON data in ANY form and wants to explore its
  structure, infer its schema, modify fields, or edit configuration files.
  This includes:
  - JSON files on disk (view, inspect, search)
  - JSON configuration files (config.json, settings.json, package.json,
    appsettings.json, tsconfig.json, .eslintrc, any *.json config)
  - Editing / updating fields in a JSON file (set key, delete key, insert
    array element, bulk update, modify nested value)
  - Inline JSON pasted into chat
  - HTTP / REST API responses (curl output, Postman captures, fetch() results)
  - WebSocket (WSS) message payloads captured from a browser or proxy
  - Polymarket or any exchange orderbook / market-data snapshots
  - Any API protocol payload (CLOB, AMM, streaming events, RPC responses)
  Triggers on: view json, edit json, json schema, json structure, set json
  field, jstool, analyze json, flat view, orderbook, json flat,
  modify json, update json, change json, json config, edit config,
  modify config, update config, set config field, change config,
  config.json, settings.json, package.json, tsconfig.json,
  delete json field, insert json, add json key, json edit,
  api response, http response, rest api json, websocket message,
  wss payload, ws frame, api payload, protocol message, clob orderbook,
  market data json, analyze api, inspect response, parse response.
allowed-tools: Bash
argument-hint: "[json-file | - (stdin) | inline JSON | api-url]"

⚠️ **MANDATORY: Use jstool instead of read/edit/cat for JSON files!**

Before using read/edit on *.json files, ask yourself:
 "Should I use jstool instead?"
  - View: `python3 ~/.agents/skills/json-flat-tool/jstool.py view <file> -s`
  - Edit: `python3 ~/.agents/skills/json-flat-tool/jstool.py set <path> <value> <file> -f`
  - Search: `python3 ~/.agents/skills/json-flat-tool/jstool.py find <pattern> <file>`

# JSON Flat Tool

A single-script tool (`jstool.py`) for viewing, inspecting, and editing JSON data.

Script path: `~/.claude/skills/json-flat-tool/jstool.py`

## Invocation

```bash
python3 ~/.claude/skills/json-flat-tool/jstool.py <command> [args]
```

## Commands

| Command | Description |
|---------|-------------|
| `view [file] [opts]` | Flat path/type/value display |
| `schema [file] [--title T]` | Infer JSON Schema Draft 7 |
| `set <path> <value> [file] [-f]` | Set a field value |
| `<path> = <value> [file] [-f]` | Same, B-style syntax |
| `before <path> <value> [file] [-f]` | Insert before array element |
| `after <path> <value> [file] [-f]` | Insert after array element |
| `del <path> [file] [-f]` | Delete a key or element |
| `set-null <path> [file] [-f]` | Set a field to null |
| `copy <src> <dst> [file] [-f]` | Deep-clone a subtree to a new path |
| `merge <path> <patch.json> [file] [-f]` | Deep-merge a JSON file into a path |
| `find <pattern> [file] [opts]` | Search paths and values by regex or glob |

Omit `[file]` to read from stdin.

## view Options

| Flag | Unit | Description |
|------|------|-------------|
| `-s` | — | Schema mode: collapse `[N]→[*]`, deduplicate, hide values |
| `-F <path>` | — | Filter: show only this path and its children |
| `-n <N>` | rows | Show at most N rows |
| `-O <N>` | rows | Skip first N rows |
| `-E <N>` | elements | Skip first N array elements (use with `-F`) |
| `-L <N>` | elements | Show at most N array elements (use with `-F`) |
| `-d <N>` | depth | Collapse containers deeper than N levels (object key depth; array indices don't count) |

`-E` and `-L` are element-aware and never cut an element in the middle.

## Edit flags

- `-f` — Force: apply change to file. Default is **preview-only**.
- Without `-f`: shows a color-annotated diff of the original JSON with `~~~~~` underline markers at the exact change position.

## Path syntax

```
root              root node
count             root-level key
users[0]          array element
users[0].name     nested key
root[0].key       root-array element key
```

## Value parsing

Values are parsed as JSON first, then fall back to plain string:

```
Alice          → string
42             → integer
3.14           → number
true / false   → boolean
null           → null
'{"k":"v"}'    → object
'[1,2,3]'      → array
@path/to.json  → read value from file
```

## Output format (view)

```
root object
users array
users[0] object
users[0].name string Alice
users[0].age integer 30
users[1].age integer (null)    ← magenta: null with inferred type
orphan unknown (null)          ← red: null, type unknown
meta object (empty)            ← dim: empty container
config object {3 keys}         ← dim: collapsed by -d
tags array [12 items]          ← dim: collapsed by -d
```

Colors: cyan = path, yellow = type, green = value,
        magenta = inferred null, red = unknown/delete, dim = empty/collapsed.

## Workflow

### Explore a JSON file

```bash
# Quick structure overview
python3 ~/.claude/skills/json-flat-tool/jstool.py view data.json -s

# Filter to a nested array, element-aware pagination
python3 ~/.claude/skills/json-flat-tool/jstool.py view data.json -F "data[0].bids" -E 5 -L 3

# Infer JSON Schema Draft 7
python3 ~/.claude/skills/json-flat-tool/jstool.py schema data.json --title "My API"

# Depth-limited view: collapse containers beyond 2 key levels
python3 ~/.claude/skills/json-flat-tool/jstool.py view data.json -d 2

# Combine with filter: expand just one branch while keeping others collapsed
python3 ~/.claude/skills/json-flat-tool/jstool.py view data.json -d 1 -F users
```

### Edit a JSON file

```bash
# Preview change (default)
python3 ~/.claude/skills/json-flat-tool/jstool.py set users[0].name Bob data.json

# Apply change
python3 ~/.claude/skills/json-flat-tool/jstool.py set users[0].name Bob data.json -f

# B-style
python3 ~/.claude/skills/json-flat-tool/jstool.py "users[0].name" = Bob data.json -f

# Insert / delete
python3 ~/.claude/skills/json-flat-tool/jstool.py before users[1] '{"name":"Eve"}' data.json -f
python3 ~/.claude/skills/json-flat-tool/jstool.py del users[2] data.json -f
python3 ~/.claude/skills/json-flat-tool/jstool.py set-null users[0].age data.json -f
```

### Set value from file (`@file`)

```bash
# Write a complex object to a file, then set it at a path
python3 ~/.claude/skills/json-flat-tool/jstool.py set provider.openai @/tmp/openai.json config.json -f
```

### Clone a subtree (`copy`)

```bash
# Clone an existing model as the base for a new one (preview)
python3 ~/.claude/skills/json-flat-tool/jstool.py copy \
  provider.google.models.antigravity-gemini-3-pro \
  provider.google.models.my-new-model \
  config.json

# Apply
python3 ~/.claude/skills/json-flat-tool/jstool.py copy \
  provider.google.models.antigravity-gemini-3-pro \
  provider.google.models.my-new-model \
  config.json -f
```

### Deep-merge a patch file (`merge`)

```bash
# patch.json only needs to contain the fields to add/update
# preview: shows which keys are added (+) and updated (~)
python3 ~/.claude/skills/json-flat-tool/jstool.py merge provider.google.models /tmp/new-models.json config.json

# Apply
python3 ~/.claude/skills/json-flat-tool/jstool.py merge provider.google.models /tmp/new-models.json config.json -f
```

### Find nodes by pattern (`find`)

```bash
# Regex search in both paths and values (default)
python3 ~/.claude/skills/json-flat-tool/jstool.py find apiKey config.json

# Search path only (-k), value only (-v)
python3 ~/.claude/skills/json-flat-tool/jstool.py find apiKey config.json -k
python3 ~/.claude/skills/json-flat-tool/jstool.py find "sk-.*" config.json -v

# Case-insensitive
python3 ~/.claude/skills/json-flat-tool/jstool.py find "APIKEY" config.json -k -i

# Glob mode (full-string wildcard, use * to match anywhere)
python3 ~/.claude/skills/json-flat-tool/jstool.py find "*api*" config.json -k -g -i
```

**find options**:

| Flag | Description |
|------|-------------|
| `-k` | Match path only |
| `-v` | Match value only |
| `-i` | Case-insensitive |
| `-g` | Glob mode (fnmatch full-string wildcard instead of regex) |

`-k` and `-v` are mutually exclusive. Without either flag, both path and value are searched.

### Inline / piped JSON

```bash
echo '{"name":"Alice"}' | python3 ~/.claude/skills/json-flat-tool/jstool.py view
curl https://api.example.com/data | python3 ~/.claude/skills/json-flat-tool/jstool.py schema
```

## HTTP API & WebSocket Analysis

**This skill should be invoked automatically whenever the user pastes an API response, curl output, WSS frame, or asks to analyze any protocol-level JSON payload.**

### Analyze an HTTP API response

```bash
# Fetch and immediately explore structure
curl -s https://api.example.com/markets | \
  python3 ~/.claude/skills/json-flat-tool/jstool.py view -s

# Infer schema from a REST endpoint
curl -s https://api.example.com/orderbook/BTC-USD | \
  python3 ~/.claude/skills/json-flat-tool/jstool.py schema --title "Orderbook API"

# Save the raw response, then explore interactively
curl -s https://api.example.com/events > /tmp/events.json
python3 ~/.claude/skills/json-flat-tool/jstool.py view /tmp/events.json -d 2

# Search for a specific field across the response
curl -s https://api.example.com/data | \
  python3 ~/.claude/skills/json-flat-tool/jstool.py find "price" -k
```

### Analyze a WebSocket (WSS) message capture

When a user pastes a raw WebSocket frame payload or a captured `.json` log:

```bash
# Paste the captured WSS JSON into a temp file, then inspect
echo '<paste-wss-frame-here>' > /tmp/wss_frame.json
python3 ~/.claude/skills/json-flat-tool/jstool.py view /tmp/wss_frame.json -s

# Compare schema across multiple frames (batch via stdin)
cat wss_frames/*.json | jq -s '.' | \
  python3 ~/.claude/skills/json-flat-tool/jstool.py schema --title "WSS Message Schema"

# Find volatile / changing fields (paginate through a large frame log)
python3 ~/.claude/skills/json-flat-tool/jstool.py view wss_log.json -F "data" -E 0 -L 5
```

### Orderbook / market-data snapshots

```bash
# Explore top-level structure
python3 ~/.claude/skills/json-flat-tool/jstool.py view orderbook.json -d 1

# Drill into bids/asks with element-aware pagination
python3 ~/.claude/skills/json-flat-tool/jstool.py view orderbook.json -F "bids" -L 10
python3 ~/.claude/skills/json-flat-tool/jstool.py view orderbook.json -F "asks" -L 10

# Infer schema to understand field types
python3 ~/.claude/skills/json-flat-tool/jstool.py schema orderbook.json --title "CLOB Orderbook"
```

### Tips for API / protocol analysis

| Scenario | Recommended command |
|---|---|
| Unknown response shape | `view -s` (schema mode) |
| Large paginated list | `view -F <array-path> -E <skip> -L <count>` |
| Find auth / key fields | `find "token\|key\|secret\|auth" -k -i` |
| Understand field types | `schema --title "<endpoint-name>"` |
| Diff two responses | save both → `set` / `merge` preview |
| WSS frame with nested events | `view -d 2` then `view -F <event-path>` |

### Inline JSON from chat

When the user pastes raw JSON directly into the conversation, save it to a temp file:

```bash
cat > /tmp/api_payload.json << 'EOF'
<paste JSON here>
EOF
python3 ~/.claude/skills/json-flat-tool/jstool.py view /tmp/api_payload.json -s
```

## Notes

- `before` / `after` only apply to **array elements**, not object keys.
- To add a new key to an object, use `set`.
- `-f` without a file path prints modified JSON to stdout.
- `-E` / `-L` require `-F` pointing to an array path.
- Array sampling for schema inference: up to 20 elements.
- `required` in schema = fields present and non-empty in all sampled elements.
- `@file` syntax works with `set` and B-style (`=`); `merge` always takes a file path directly.
- `copy` performs a deep clone — mutations to the copy do not affect the source.
- `merge` for non-dict targets replaces the value entirely (patch wins).
- `find -g` uses `fnmatch` (full-string wildcard): use `*api*` not `api*` for substring matching.
- `find` without `-g` uses Python `re.search` (substring regex by default).
- `-d N` only affects the flat view display; schema inference and edit commands are unaffected.
- `-d N` depth counts object key traversals only — array indices (`[0]`, `[1]`, …) do not increment depth.
