costa-marcello research: Deep Research Any Topic
Research ANY topic across Reddit, X, community forums, official docs, academic papers, and industry publications. Dispatches 6-10 parallel sub-agents to cover every angle — community AND official sources — then synthesizes a two-sided report.
Use cases:
- Prompting: "photorealistic people in Nano Banana Pro" — learn techniques from community tips AND official guides
- Recommendations: "best Claude Code skills" — get specific names from community + official feature comparisons
- News: "what's happening with OpenAI" — community reactions + official announcements
- General: any topic — understand what the community says AND what officials report
Parse User Intent
User input: $ARGUMENTS
Extract four variables from user input before proceeding:
| Variable | Extract | Example |
|---|---|---|
TOPIC |
What they want to learn about | "web app mockups", "Claude Code skills" |
TARGET_TOOL |
Where they'll use prompts (or "unknown") | "Nano Banana Pro", "Midjourney" |
QUERY_TYPE |
PROMPTING | RECOMMENDATIONS | NEWS | GENERAL | Auto-detect from phrasing |
DEPTH |
--quick (6 agents) | default (8) | --deep (10) |
Flag in user input |
See references/intent_parsing.md for query type definitions, detection patterns, and variable storage rules.
Do not ask about target tool before research. If unspecified, ask after showing results.
Setup Check
The Python script works in three modes based on available API keys:
- Full Mode (both keys): Reddit + X with real engagement metrics
- Partial Mode (one key): Reddit-only or X-only
- Web-Only Mode (no keys): Script provides no data, sub-agents do all the work
API keys are optional. The skill always dispatches sub-agents regardless. Determine mode quickly.
MCP Tool Detection
Discover available search MCP tools before dispatching agents. Run ToolSearch for EACH query below and record every tool found as AVAILABLE_MCP_TOOLS:
| Query | Known tool names |
|---|---|
"searxng" |
searxng_web_search, web_url_read |
"brave search" |
brave_web_search, brave_news_search, brave_local_search, brave_image_search, brave_video_search |
"exa" |
exa_search, exa_find_similar, exa_get_contents |
"tavily" |
tavily_search, tavily_extract |
"firecrawl" |
firecrawl_search, firecrawl_scrape, firecrawl_crawl, firecrawl_map |
"perplexity" |
perplexity_ask |
"jina" |
jina_search, jina_read_url |
"kagi" |
kagi_search, kagi_summarize |
"serper" |
serper_google_search, serper_news_search |
"google search" |
google_web_search |
Run all ToolSearch calls in a single parallel message. Any tool that appears in the results is loaded and available.
Construct the MCP_TOOLS instruction block embedded into every sub-agent prompt:
- MCP tools found: List discovered tools by name. Instruct agents to use them as PRIMARY search tools, falling back to harness tools only on errors or empty results.
- No MCP tools found: Instruct agents to use harness-provided tools in this order:
WebSearch/WebFetch(Claude Code built-in)antigravity_search/ Antigravity search tools (if available)codex_search/ Codex search tools (if available)
Phase 1: Run Python Script (Reddit + X)
Run the research script synchronously — it provides Reddit/X data with real engagement metrics that sub-agents cannot replicate.
RESEARCH_SCRIPT="$([ -f .claude/skills/research/scripts/research.py ] && echo .claude/skills/research/scripts/research.py || echo ~/.claude/skills/research/scripts/research.py)" && python3 "$RESEARCH_SCRIPT" "$TOPIC" --emit=compact 2>&1
The $DEPTH flag maps to: --quick -> pass --quick; default -> no flag; --deep -> pass --deep.
Store the output as SCRIPT_DATA. Check mode from output:
- "Mode: both" / "Mode: reddit-only" / "Mode: x-only": Script found data
- "Mode: web-only": No API keys, sub-agents provide all data
Do not stop or warn if web-only. Proceed to Phase 2.
Orchestrator Prompting Primer
You are the research lead, not a dispatcher. Sub-agent output quality is bounded by the prompts you hand them. Before filling any template, apply these four rules:
Topic-specific queries, not category queries. Rewrite any query that could apply to a whole category of tools.
- BAD:
"best image generation models 2026" - GOOD:
"Nano Banana Pro photorealistic people fine-tuning tips"
- BAD:
Diversify angles across the 3-5 queries. Each query for a single agent must probe a different angle (recommendations vs critiques vs how-to vs comparisons vs pitfalls). Duplicate queries waste an agent slot.
Match query verbs to
QUERY_TYPE.- RECOMMENDATIONS:
"best","top","vs","alternative to" - NEWS:
"announcement","reaction to","what happened with" - PROMPTING:
"prompt for","technique","example of" - GENERAL:
"how does X work","X explained"
- RECOMMENDATIONS:
Route contradictions and Tier C-only evidence into Phase 4 weighting. When an agent flags disagreement or only low-tier sources, do not ignore it — note it and weight it lower in synthesis.
Phase 2: Sub-Agent Dispatch
Dispatch the exact agent count below. Each agent targets its specific focus area -- do not reduce the count or use generic agents.
Step 1: Read Prompt Templates
Use the Read tool to read references/subagent_prompts.md BEFORE constructing any prompts. That file contains the Community Agent Template and Official Agent Template you must fill for each agent.
Step 2: Agent Roles
Agent count by depth: --quick = 6 (3C + 3O) | default = 8 (4C + 4O) | --deep = 10 (5C + 5O)
Community agents (exclude reddit.com and x.com from all searches):
| Agent | Focus | When Active |
|---|---|---|
| C1 | HN + tech forums (Lobsters, Stack Overflow) | Always |
| C2 | Broader community (forums, Discourse, Product Hunt) | Always |
| C3 | Niche communities + comparisons (review sites, specialised forums) | Always |
| C4 | Developer/creator communities (Dev.to, GitHub Discussions, blogs) | default + deep |
| C5 | International perspectives + user reviews (G2, Capterra, global forums) | deep only |
Official agents:
| Agent | Focus | When Active |
|---|---|---|
| O1 | Official docs + changelogs + release notes | Always |
| O2 | Industry publications + analysis (Ars Technica, Wired, InfoQ) | Always |
| O3 | Academic papers + research (arXiv, Google Scholar) | Always |
| O4 | Government/institutional + standards bodies | default + deep |
| O5 | Expert blogs + thought leadership | deep only |
Step 3: Dispatch
For each agent, fill the matching template from references/subagent_prompts.md with: {TOPIC}, {QUERY_TYPE}, {FOCUS}, {QUERIES} (3-5 queries from references/subagent_prompts.md Query Generation tables, with {CURRENT_YEAR} substituted using the system date), {DATE_FROM} (60 days ago), {CURRENT_YEAR}, {MCP_TOOLS}.
Every Task call uses subagent_type: "general-purpose" and a description matching the agent role (e.g. "C1: HN + tech forums", "O2: industry pubs").
Dispatch ALL agents in a SINGLE message with parallel Task calls. Do not dispatch sequentially.
Phase 3: Collect Results
After dispatching, collect results from all agents:
- Call
TaskOutputfor each dispatched agent - Organize into:
COMMUNITY_FINDINGS(C1-C5) andOFFICIAL_FINDINGS(O1-O5) - Graceful failure: If an agent fails or returns empty, log which agent failed, continue with remaining results, note the gap in the final report. Do not retry.
Phase 4: Judge Synthesis
Synthesize all findings (SCRIPT_DATA + COMMUNITY_FINDINGS + OFFICIAL_FINDINGS) into a coherent two-sided report.
Weighting
| Source | Weight | Why |
|---|---|---|
| Reddit (from script) | HIGHEST | Real upvotes + comments = proven engagement |
| X (from script) | HIGHEST | Real likes + reposts = proven engagement |
| HN / Lobsters | HIGH | Voting system = community curation |
| Official docs | HIGH | Authoritative, primary source |
| Academic papers | HIGH | Peer-reviewed |
| Industry publications | MEDIUM | Expert but potentially biased |
| Expert blogs | MEDIUM-LOW | Individual perspective |
| Misc community | MEDIUM-LOW | Volume varies |
Cross-Reference Analysis
Identify 3-5 topics where community and official sources can be compared:
- Aligned: Both sides agree
- Divergent: Community says one thing, officials say another
- Gap: One side has information the other lacks
Internalize the Research
Ground your synthesis in actual research content, not pre-existing knowledge. Read all agent outputs carefully, paying attention to exact names, specific insights, and real engagement numbers.
If QUERY_TYPE = RECOMMENDATIONS
Extract specific names from all sources (script + community + official agents). Count mentions across sources, note which sources recommend each, list by popularity.
For All Query Types
From the actual research output, identify:
- PROMPT FORMAT — Does research recommend JSON, structured params, natural language, keywords?
- Top 3-5 patterns/techniques that appeared across multiple sources
- Specific keywords, structures, or approaches mentioned by the sources
- Common pitfalls mentioned by the sources
If research says "use JSON prompts" or "structured prompts", deliver prompts in that format later.
Before displaying, trace every specific claim (names, numbers, quotes, version strings) to an agent output. If a claim has no traceable source, remove it.
Display Two-Sided Report
Refer to references/output_format.md for the full template. Do not output any "Sources:" lists.

5. Invitation
Share your vision for what you want to create and I'll write a thoughtful prompt
you can copy-paste directly into {TARGET_TOOL}.
Use real numbers from the research output. Patterns should be actual insights, not generic advice.
If TARGET_TOOL is still unknown after showing results, ask now:
What tool will you use these prompts with?
Options:
1. [Most relevant tool based on research]
2. Nano Banana Pro (image generation)
3. ChatGPT / Claude (text/code)
4. Other (tell me)
After displaying the report and invitation, wait for the user to respond.
Prompt Generation
When the user shares their vision, write ONE tailored prompt using expertise from BOTH community and official sources.
Match the format the research recommends (JSON, structured params, natural language, keywords).
See references/prompt_generation.md for the full prompt writing protocol, quality checklist, and output footer templates.
Context Memory
After research completes, retain topic expertise for follow-up questions. See references/context_memory.md for full context retention protocol.
