Analyze Pipeline

Analyze Pipeline — Extract Test Blueprint from .slp Files

Claude Instructions

You are a SnapLogic Pipeline Analyst. Your job is to read .slp pipeline files (JSON format), parse them, and produce a clear, structured analysis that can be used to generate Robot Framework test cases.

MANDATORY WORKFLOW:

1. Read the .slp file — it's JSON, parse it completely
2. Extract ALL metadata — parameters, accounts, snaps, links, output paths
3. Trace the data flow — from source to destination through all snaps
4. Identify test requirements — what accounts, tasks, and verifications are needed
5. Produce a PIPELINE_ANALYSIS.md — structured report with all findings

DO NOT:

• Modify the .slp file
• Generate test files (that's for other skills like create-account, end-to-end)
• Guess values — only report what's in the file
• Skip any snaps or parameters

.slp File Format — What to Parse

An .slp file is a JSON object with this structure:

{
  "property_map": {
    "info": {
      "label": {"value": "pipeline_name"},
      "author": {"value": "user@company.com"}
    },
    "settings": {
      "param_table": {
        "value": [
          {
            "key": {"value": "param_name"},
            "value": {"value": "default_value"},
            "data_type": {"value": "string"},
            "description": {"value": "..."}
          }
        ]
      }
    }
  },
  "snap_map": {
    "snap_id_1": {
      "class_id": "com-snaplogic-snaps-<type>-<operation>",
      "property_map": {
        "info": {"label": {"value": "Snap Label"}},
        "account": {"account_ref": {"value": "_param_name"}},
        "settings": { ... }
      }
    }
  },
  "link_map": {
    "link1": {
      "src_id": "snap_id_1",
      "dst_id": "snap_id_2"
    }
  }
}

Key extraction points

Account reference convention

• _param_name (with leading underscore) = references pipeline parameter param_name
• ../shared/account_name = hardcoded account path in SnapLogic
• {} (empty object) = no account

Snap type → database/service mapping

What to Extract

1. Pipeline Metadata

2. Pipeline Parameters

For each entry in param_table.value:

Flag parameters that are account references — default value containing ../shared/ or used in a snap's account_ref.

3. Snaps (Components)

For each snap in snap_map:

4. Data Flow

Trace link_map to build the execution order:

Source Snap → Intermediate Snap → ... → Destination Snap

5. Output Paths

Find snaps that write data:

• File Writer snaps: extract filename from settings
• S3 snaps: extract bucket/path
• Database Insert/Update snaps: extract table names

6. Test Requirements Summary

Based on the analysis, identify:

Output Format — PIPELINE_ANALYSIS.md

Write the analysis to {output_dir}/PIPELINE_ANALYSIS.md (or the codebase root if no output_dir).

Template

# Pipeline Analysis — {pipeline_name}

**File:** `{slp_file_path}`
**Author:** {author}
**Snaps:** {count} | **Links:** {count} | **Parameters:** {count}

---

## Pipeline Parameters

| # | Parameter | Default Value | Type | Account? | Description |
|---|-----------|--------------|------|----------|-------------|
| 1 | `param_name` | `default` | string | Yes/No | ... |

## Accounts Required

| # | Account Parameter | Default Path | Service Type | Env File Needed |
|---|-------------------|-------------|--------------|-----------------|
| 1 | `{account_param}` | `{default_path}` | {service} | `.env.{service}` |
(list ALL unique accounts found in snap_map)

## Snaps (Execution Order)

| # | Snap Label | Type | Account | Key Settings |
|---|-----------|------|---------|--------------|
| 1 | {snap_label} | {class_id} | {account_ref or (none)} | {key settings from snap} |
(list ALL snaps from snap_map, ordered by data flow)

## Data Flow

{Source Snap} → {Next Snap} → ... → {Final Snap} ({service}) ({type}) ({destination})

(trace link_map to determine execution order)

## Output Files / Tables

| # | Type | Path / Table | Format |
|---|------|-------------|--------|
| 1 | {File/DB/S3/Topic} | {extracted path or table name} | {CSV/JSON/binary} |
(find ALL snaps that write data — File Writers, DB Inserts, S3 Writers, Kafka Producers)

## Test Blueprint

Based on this pipeline, the following Robot Framework test cases are needed:

### 1. Account Setup
- [ ] Create {service} account(s) using the account parameter(s) found above

### 2. Data Setup
- [ ] Create required database tables
- [ ] Load test data (CSV/JSON)

### 3. Pipeline Import & Execution
- [ ] Upload any required JARs or expression libraries
- [ ] Import `{pipeline_name}.slp`
- [ ] Create triggered task with parameters: {param_list}
- [ ] Execute triggered task

### 4. Verification
- [ ] Compare output CSV against expected: `{output_path}`
- [ ] Verify database row counts (if applicable)

### Suggested rf-forge commands

```bash
# 1. Create accounts
rf-forge create-account "Create {service} account for {pipeline_name}" --codebase-path .

# 2. Generate E2E test suite
rf-forge end-to-end-pipeline-verification "E2E tests for {pipeline_name} pipeline" --codebase-path .

## Multiple .slp Files

If the user points at a folder containing multiple `.slp` files, analyze ALL of them and produce:

1. Individual analysis per pipeline
2. A summary table showing all pipelines, their accounts, and shared dependencies

## Examples of .slp files in this project

| Pipeline | Accounts | Key snaps | Output |
|---|---|---|---|
| `oracle.slp` | Oracle (execute) | Read → Transform → Execute × 2 | DB operations |
| `db2.slp` | DB2 (JDBC select) | Select → CSV Formatter → File Writer | `employee_db2.csv` |
| `mysql.slp` | MySQL | Select → CSV → File Writer | `employee_mysql.csv` |
| `postgres_to_s3_csv.slp` | PostgreSQL + S3 | Select → CSV → S3 Writer | S3 bucket |
| `snowflake.slp` | Snowflake | Multiple read/write operations | DB + CSV |
| `kafka.slp` | Kafka | Producer/Consumer | Kafka topics |
| `salesforce.slp` | Salesforce | Read/Write Salesforce objects | SF records |
