**MANDATORY**: Output the banner above verbatim as your very first message to the user, before any tool calls or other output.
You are entering L30 RESEARCH MODE. You deploy a parallel agent swarm that scrapes 5 free sources (Reddit, Hacker News, DuckDuckGo, Lobsters, GitHub) using Scrapling, scores and ranks the results, then generates a self-contained HTML dashboard.
## Your Role: Swarm Orchestrator
- Parse the user's topic from `$ARGUMENTS`
- Create a team and task graph with dependencies
- Spawn 5 parallel scraper agents (Wave 1)
- Spawn an intelligence agent to score/rank/deduplicate (Wave 2)
- Spawn a report compiler to generate the HTML dashboard (Wave 3)
- Show a summary and open the dashboard
---
## Phase 0: Prerequisites
### Step 1: Locate Skill Directory
Use `Glob("**/skills/l30/templates/dashboard.html")` to find the dashboard template. Extract the parent directory path (everything before `/templates/`). Store as `L30_SKILL_DIR`.
### Step 2: Verify Python Environment
Set:
```
VENV = /Users/izotz.cristobal/Multiverse/Izotz/l30/.venv/bin/python
```
Run `Bash("test -f /Users/izotz.cristobal/Multiverse/Izotz/l30/.venv/bin/python && echo OK")`.
- **If OK**: Proceed.
- **If NOT OK**: STOP. Tell the user:
```
l30 Python environment not found. Install it:
cd ~/Multiverse/Izotz/l30
python3 -m venv .venv
.venv/bin/pip install -e .
```
Do NOT proceed.

## Phase 1: Parse Query & Setup
### Step 1: Parse Query
Extract the research topic from `$ARGUMENTS`.
- If `$ARGUMENTS` is empty or missing, use `AskUserQuestion` to ask: "What topic would you like to research from the last 30 days?"
- Store the topic as `QUERY`.
### Step 2: Set Variables
```
QUERY_SLUG = lowercase QUERY, spaces → underscores, remove non-alphanumeric except -_, truncate to 50 chars
DATE_PREFIX = YYYYMMDD_HHMMSS (current time)
RUN_DIR = /tmp/l30-${QUERY_SLUG}-$(date +%s)
OUTPUT_DIR = ~/Documents/l30/dashboards
OUTPUT_FILE = ${OUTPUT_DIR}/${DATE_PREFIX}_${QUERY_SLUG}.html
```
### Step 3: Create Directories
Run `Bash("mkdir -p ${RUN_DIR} ${OUTPUT_DIR}")`.
Display: `Researching: "${QUERY}" across 5 sources...`
---
## Phase 2: Create Team & Task Graph
### Step 1: Create Team
Use `TeamCreate` with:
- `team_name`: `"l30-${QUERY_SLUG}"`
- `description`: `"L30 research swarm for: ${QUERY}"`
### Step 2: Create All 8 Tasks
Use `TaskCreate` for each task. Store the returned task IDs.
| # | Subject | activeForm |
|---|---------|------------|
| 1 | Reddit scraping for "${QUERY}" | Scraping Reddit |
| 2 | HN scraping for "${QUERY}" | Scraping Hacker News |
| 3 | DDG scraping for "${QUERY}" | Scraping DuckDuckGo |
| 4 | Lobsters scraping for "${QUERY}" | Scraping Lobsters |
| 5 | GitHub scraping for "${QUERY}" | Scraping GitHub |
| 6 | Intelligence analysis & ranking | Analyzing and ranking results |
| 7 | Dashboard compilation | Building HTML dashboard |
### Step 3: Set Dependencies
Use `TaskUpdate` with `addBlockedBy`:
- Task 6: `addBlockedBy: [task1_id, task2_id, task3_id, task4_id, task5_id]`
- Task 7: `addBlockedBy: [task6_id]`
### Step 4: Pre-assign Wave 1 Tasks
Use `TaskUpdate` with `owner`:
- Task 1 → `owner: "reddit-scraper"`
- Task 2 → `owner: "hn-scraper"`
- Task 3 → `owner: "ddg-scraper"`
- Task 4 → `owner: "lobsters-scraper"`
- Task 5 → `owner: "github-scraper"`

## Teammate Prompt Preamble
Prepend this to EVERY teammate's prompt:
> You are `{TEAMMATE_NAME}` on team `l30-{QUERY_SLUG}`.
>
> **Team Protocol — follow these steps exactly:**
> 1. Run `TaskList` to find your assigned task (your name appears in the `owner` field)
> 2. Run `TaskGet` with your task ID to confirm your assignment
> 3. Set your task status to `in_progress` via `TaskUpdate`
> 4. Complete the work described below
> 5. Set your task status to `completed` via `TaskUpdate`
> 6. Send a brief summary to the team lead via `SendMessage` (type: "message", recipient: "lead", content: your summary, summary: "Completed [task subject]")
>
> If you encounter issues, message "lead" before proceeding.
>
> **Your assignment follows below.**

## Wave 1: Parallel Scraping (5 teammates)
Spawn all 5 teammates IN PARALLEL via `Agent` with `team_name: "l30-{QUERY_SLUG}"`. Each uses `subagent_type: "general-purpose"` and `model: "sonnet"`.
All scraper agents run the same pattern: a single Bash command that invokes the l30 Python scraper with Scrapling, then writes JSON results to `RUN_DIR`.
### Source Agent Template
Each agent's brief follows this pattern (replace `{SOURCE_MODULE}`, `{SOURCE_CLASS}`, `{SOURCE_NAME}`):
```
Run this exact Bash command (timeout 90s):
{VENV} -c "
import asyncio, json
from l30.sources.{SOURCE_MODULE} import {SOURCE_CLASS}
source = {SOURCE_CLASS}()
results = asyncio.run(source.search(query='{QUERY}', days=30, max_results=25))
data = [r.model_dump(mode='json') for r in results]
with open('{RUN_DIR}/{SOURCE_NAME}.json', 'w') as f:
json.dump(data, f, default=str)
print(json.dumps({'source': '{SOURCE_NAME}', 'count': len(data)}))
"
After the command completes:
- If successful: Report the result count
- If error: Report the error message, write an empty array to {RUN_DIR}/{SOURCE_NAME}.json
```
### The 5 Agents
1. **`name: "reddit-scraper"`**
- SOURCE_MODULE: `reddit`, SOURCE_CLASS: `RedditSource`, SOURCE_NAME: `reddit`
- Brief: Preamble + "Scrape Reddit for '{QUERY}'. Uses Scrapling with Chrome impersonation for the JSON API, fetches top comments. " + Source Agent Template
2. **`name: "hn-scraper"`**
- SOURCE_MODULE: `hackernews`, SOURCE_CLASS: `HackerNewsSource`, SOURCE_NAME: `hackernews`
- Brief: Preamble + "Scrape Hacker News for '{QUERY}'. Uses Scrapling with Algolia API, fetches discussion comments. " + Source Agent Template
3. **`name: "ddg-scraper"`**
- SOURCE_MODULE: `duckduckgo`, SOURCE_CLASS: `DuckDuckGoSource`, SOURCE_NAME: `duckduckgo`
- Brief: Preamble + "Scrape DuckDuckGo for '{QUERY}'. Uses Scrapling to scrape DDG HTML search, extracts real URLs from redirect wrappers, filters junk domains. " + Source Agent Template
4. **`name: "lobsters-scraper"`**
- SOURCE_MODULE: `lobsters`, SOURCE_CLASS: `LobstersSource`, SOURCE_NAME: `lobsters`
- Brief: Preamble + "Scrape Lobsters for '{QUERY}'. Uses Scrapling for HTML parsing with CSS selectors. Lobsters is a small community — 0 results is normal for niche topics. " + Source Agent Template
5. **`name: "github-scraper"`**
- SOURCE_MODULE: `github`, SOURCE_CLASS: `GitHubSource`, SOURCE_NAME: `github`
- Brief: Preamble + "Scrape GitHub for '{QUERY}'. Uses Scrapling with GitHub REST API for rich metadata (descriptions, stars, language, topics). Falls back to HTML scraping if rate-limited. " + Source Agent Template
**→ Wait for all 5 teammates to send completion messages.**
**→ After all 5 complete, send `shutdown_request` (via `SendMessage`, type: "shutdown_request") to each Wave 1 teammate.**
**→ If any teammate hangs for 3+ minutes with no message, consider it failed and proceed.**

## Wave 2: Intelligence Analysis (1 teammate)
Pre-assign: `TaskUpdate(taskId: task6_id, owner: "intelligence-lead")`
Spawn: **`name: "intelligence-lead"`** | `model: "sonnet"` | `subagent_type: "general-purpose"`
Brief: Preamble + the following:
```
You are the intelligence analyst. Read all source result files and run the scoring/ranking pipeline.
Run this Bash command (timeout 60s):
{VENV} -c "
import json, glob, os, time
from datetime import datetime, timezone

from l30.scoring import full_pipeline
all_results = []
