research-external is a Claude Code skill that runs an autonomous external research workflow for documentation, web sources, and APIs so coding agents gather fresh library and market data without leaving the session.
About
research-external from continuous-claude-v3 is an external research workflow invoked as /research-external with optional focus and flags. It researches documentation, web pages, and APIs for libraries, best practices, and general topics—not local codebase exploration. The skill uses Bash, Read, Write, and Task tools under a sonnet model and guides users through phased AskUserQuestion flows when arguments are partial. Documentation anchors best practices to 2024–2025. Developers reach for research-external when competitor intel, API docs, or market signals must be collected autonomously mid-flow.
- Enables Claude to perform real-time web searches, scrape documentation, and synthesize findings directly inside your cod
- Reduces context-window waste by letting the agent fetch only what it needs when it needs it.
- Supports parallel research across multiple sources in one turn.
- Designed as a core building block for continuous Claude workflows.
- Returns structured summaries and citations the agent can immediately act upon.

How do coding agents research external docs and APIs?
Let their coding agent autonomously gather fresh external data, competitor intel, API docs, or market signals without leaving the flow.
Who is it for?
Developers who need autonomous external doc, API, and web research inside Claude Code without manual tab switching.
Skip if: Searching or refactoring the local repository, or tasks solvable entirely from files already in the workspace.
When should I use this skill?
Fresh API docs, competitor intel, library best practices, or market signals are needed from outside the codebase.
What you get
External research notes, API documentation summaries, and web-sourced best-practice findings saved to the session.
- External research summary
- API documentation notes
- Web-sourced best-practice report

External Research Workflow
Research external sources (documentation, web, APIs) for libraries, best practices, and general topics.
Note: The current year is 2025. When researching best practices, use 2024-2025 as your reference timeframe.
Invocation
/research-external <focus> [options]Question Flow (No Arguments)
If the user types just /research-external with no or partial arguments, guide them through this question flow. Use AskUserQuestion for each phase.

description: "Go packages"Then ask for specific library name if not already provided.
Phase 4: Depth
question: "How thorough should the research be?"
header: "Depth"
options:
- label: "Quick answer"
description: "Just the essentials"
- label: "Thorough research"
description: "Multiple sources, examples, edge cases"Mapping:

description: "Tell me what you found"
- label: "Research document"
description: "Write to thoughts/shared/research/"
- label: "Handoff for implementation"
description: "Prepare context for coding"Mapping:
- "Research document" → --output doc
- "Handoff" → --output handoff
Summary Before Execution
Based on your answers, I'll research:
**Focus:** library
**Topic:** "Prisma ORM connection pooling"
**Library:** prisma (npm)
**Depth:** thorough
**Output:** doc
Proceed? [Yes / Adjust settings]Focus Modes (First Argument)
| Focus | Primary Tool | Purpose |
|---|---|---|
library | nia-docs | API docs, usage patterns, code examples |
best-practices | perplexity-search | Recommended approaches, patterns, comparisons |
general | All MCP tools | Comprehensive multi-source research |
Options
| Option | Values | Description |
|---|---|---|
--topic | "string" | Required. The topic/library/concept to research |
--depth | shallow, thorough | Search depth (default: shallow) |
--output | handoff, doc | Output format (default: doc) |
--library | "name" | For library focus: specific package name |
--registry | npm, py_pi, crates, go_modules | For library focus: package registry |
Workflow
Step 1: Parse Arguments
Extract from user input:
FOCUS=$1 # library | best-practices | general
TOPIC="..." # from --topic
DEPTH="shallow" # from --depth (default: shallow)
OUTPUT="doc" # from --output (default: doc)
LIBRARY="..." # from --library (optional)
REGISTRY="npm" # from --registry (default: npm)Step 2: Execute Research by Focus
Focus: library
Primary tool: nia-docs - Find API documentation, usage patterns, code examples.
# Semantic search in package
(cd $CLAUDE_OPC_DIR && uv run python -m runtime.harness scripts/mcp/nia_docs.py \
--package "$LIBRARY" \
--registry "$REGISTRY" \
--query "$TOPIC" \
--limit 10)
# If thorough depth, also grep for specific patterns
(cd $CLAUDE_OPC_DIR && uv run python -m runtime.harness scripts/mcp/nia_docs.py \
--package "$LIBRARY" \
--grep "$TOPIC")
# Supplement with official docs if URL known
(cd $CLAUDE_OPC_DIR && uv run python -m runtime.harness scripts/mcp/firecrawl_scrape.py \
--url "https://docs.example.com/api/$TOPIC" \
--format markdown)Thorough depth additions:
- Multiple semantic queries with variations
- Grep for specific function/class names
- Scrape official documentation pages
Focus: best-practices
Primary tool: perplexity-search - Find recommended approaches, patterns, anti-patterns.
# AI-synthesized research (sonar-pro)
(cd $CLAUDE_OPC_DIR && uv run python scripts/mcp/perplexity_search.py \
--research "$TOPIC best practices 2024 2025")
# If comparing alternatives
(cd $CLAUDE_OPC_DIR && uv run python scripts/mcp/perplexity_search.py \
--reason "$TOPIC vs alternatives - which to choose?")Thorough depth additions:
# Chain-of-thought for complex decisions
(cd $CLAUDE_OPC_DIR && uv run python scripts/mcp/perplexity_search.py \
--reason "$TOPIC tradeoffs and considerations 2025")
# Deep comprehensive research
(cd $CLAUDE_OPC_DIR && uv run python scripts/mcp/perplexity_search.py \
--deep "$TOPIC comprehensive guide 2025")
# Recent developments
(cd $CLAUDE_OPC_DIR && uv run python scripts/mcp/perplexity_search.py \
--search "$TOPIC latest developments" \
--recency month --max-results 5)Focus: general
Use ALL available MCP tools - comprehensive multi-source research.
Step 2a: Library documentation (nia-docs)
(cd $CLAUDE_OPC_DIR && uv run python -m runtime.harness scripts/mcp/nia_docs.py \
--search "$TOPIC")Step 2b: Web research (perplexity)
(cd $CLAUDE_OPC_DIR && uv run python scripts/mcp/perplexity_search.py \
--research "$TOPIC")Step 2c: Specific documentation (firecrawl)
# Scrape relevant documentation pages found in perplexity results
(cd $CLAUDE_OPC_DIR && uv run python -m runtime.harness scripts/mcp/firecrawl_scrape.py \
--url "$FOUND_DOC_URL" \
--format markdown)Thorough depth additions:
- Run all three tools with expanded queries
- Cross-reference findings between sources
- Follow links from initial results for deeper context
Step 3: Synthesize Findings
Combine results from all sources:
1. Key Concepts - Core ideas and terminology 2. Code Examples - Working examples from documentation 3. Best Practices - Recommended approaches 4. Pitfalls - Common mistakes to avoid 5. Alternatives - Other options considered 6. Sources - URLs for all citations
Step 4: Write Output
Output: doc (default)

Ready for plan-agent to continue.Error Handling
If an MCP tool fails (API key missing, rate limited, etc.):
1. Log the failure in output:
tool_status:
nia: success
perplexity: failed (rate limited)
firecrawl: skipped2. Continue with other sources - partial results are valuable
3. Set status appropriately:
complete- All requested tools succeededpartial- Some tools failed, findings still usefulfailed- No useful results obtained
4. Note gaps in findings:
## Gaps

Notes
- NOT for codebase exploration - Use
research-codebaseorscoutfor that - Always cite sources - Include URLs for all findings
- 2024-2025 timeframe - Focus on current best practices
- Graceful degradation - Partial results better than no results

FAQ
Does research-external search the local codebase?
research-external researches external sources—documentation, web, and APIs—for libraries and best practices. The skill explicitly excludes codebase exploration, which belongs to separate internal search workflows.
How is research-external invoked in Claude Code?
research-external runs via /research-external with a focus topic and optional flags. If arguments are missing, the skill guides users through phased AskUserQuestion prompts before research begins.
