Local Deep Research

Performs multi-cycle, iterative deep research on complex topics using a local LDR service, providing detailed reports with citations and source tracking.

Local Deep Research Skill

This skill interfaces with a locally-hosted LDR (Local Deep Research) service to perform multi-cycle, iterative research with full citations and source tracking.

What to consider before installing

• LDR service: The script talks only to the URL in LDR_BASE_URL (default http://127.0.0.1:5000). Only point it at an LDR instance you control. Do not set it to an unknown or untrusted remote host.
• Required binaries: Ensure curl and jq are installed on the host where the skill runs.
• Credentials: If your LDR instance requires login, set LDR_SERVICE_USER and LDR_SERVICE_PASSWORD (or LDR_USERNAME/LDR_PASSWORD) via environment variables or a local .env file only. Use a dedicated, low-privilege LDR account (e.g. openclaw_service). Do not store secrets in committed config or in the skill directory.
• Sourced .env: The script optionally sources ~/.config/local_deep_research/config/.env if that file exists. That file may expose any variables it contains to the script. Verify the contents of that path before use; do not place unrelated secrets there.
• Review the script: The script performs form-based session+CSRF login and uses an ephemeral cookie jar. It does not send data to any endpoint other than the configured LDR service. You can review scripts/ldr-research.sh before use. For higher assurance, run it in an isolated environment (e.g. container or VM) with network restricted to your LDR host.

Configuration

Credentials (local-only, never transmitted)

LDR uses session-cookie auth with CSRF protection (not HTTP Basic Auth). The skill script performs a proper login flow: GET login page → obtain session cookie and CSRF token → POST credentials + CSRF → reuse session cookie (and CSRF for POSTs) for all API calls. Username and password are used only to create a session with your local LDR instance; they are never sent to ClawHub, GitHub, or any other server.

Do not put credentials in skill config or committed files. Use environment variables or a local .env file only (e.g. LDR_SERVICE_USER, LDR_SERVICE_PASSWORD, or LDR_USERNAME/LDR_PASSWORD). Optional: LDR’s ~/.config/local_deep_research/config/.env is sourced by the script if present. Use a dedicated LDR user (e.g. openclaw_service) for this skill.

All configuration options

• LDR_BASE_URL — LDR service URL (default: http://127.0.0.1:5000)
• LDR_LOGIN_URL — Login page URL for session + CSRF (default: $LDR_BASE_URL/auth/login)
• LDR_SERVICE_USER or LDR_USERNAME — LDR account username (local auth only)
• LDR_SERVICE_PASSWORD or LDR_PASSWORD — LDR account password (local auth only)
• LDR_DEFAULT_MODE — Default research mode: quick (Quick Summary) or detailed (Detailed Report) (default: detailed)
• LDR_DEFAULT_LANGUAGE — Default output language code for report/summary (e.g. en, es, fr, de, zh, ja); empty = LDR default
• LDR_DEFAULT_SEARCH_TOOL — Default search tool: searxng, auto, local_all (default: auto)

Research modes (Quick Summary vs Detailed Report)

• quick — Quick Summary: fewer cycles, shorter output, faster. Use when the user wants a concise summary or a quick overview.
• detailed — Detailed Report: full multi-cycle research, full markdown report, full citations and sources. Use when the user wants comprehensive analysis, literature review, or in-depth coverage.

Actions

start_research

Fire-and-forget: submit a query to LDR and return a research ID immediately.

Inputs:

• query (required) — The research question or topic
• mode (optional) — quick (Quick Summary) or detailed (Detailed Report) (default from config)
• language (optional) — Output language for the report/summary, e.g. en, es, fr, de, zh, ja (default from config or LDR default)
• search_tool (optional) — searxng, auto, local_all (default from config)
• iterations (optional) — Number of research cycles (default: LDR's default)
• questions_per_iteration (optional) — Questions to generate per cycle

Returns:

json

{
  "research_id": "uuid-string",
  "mode": "detailed",
  "search_tool": "auto",
  "submitted_at": "2026-03-10T08:00:00Z",
  "status": "queued"
}

Usage:

bash

# Quick Summary (faster, shorter)
scripts/ldr-research.sh start_research --query "Solid-state battery advances" --mode quick

# Detailed Report with output in Spanish
scripts/ldr-research.sh start_research \
  --query "What are the latest developments in solid-state batteries?" \
  --mode detailed \
  --language es \
  --search_tool searxng

get_status

Check the status of a research job.

Inputs:

• research_id (required) — The research job ID from start_research

Returns:

json

{
  "research_id": "uuid-string",
  "state": "pending|running|completed|failed|timeout",
  "progress": 45,
  "message": "Synthesizing sources from iteration 2...",
  "last_milestone": "Generated 12 questions from 8 sources"
}

Usage:

bash

scripts/ldr-research.sh get_status --research_id <uuid>

get_result

Fetch the complete research report once finished.

Inputs:

• research_id (required) — The research job ID

Returns:

json

{
  "research_id": "uuid-string",
  "query": "original query",
  "mode": "detailed",
  "summary": "executive summary text",
  "report_markdown": "full markdown report",
  "sources": [
    {
      "id": 1,
      "title": "Source Title",
      "url": "https://example.com",
      "snippet": "relevant excerpt",
      "type": "web|local_doc"
    }
  ],
  "iterations": 3,
  "created_at": "2026-03-10T08:00:00Z",
  "completed_at": "2026-03-10T08:15:00Z"
}

Usage:

bash

scripts/ldr-research.sh get_result --research_id <uuid>

Orchestration Pattern

One-shot (wait for completion)

For interactive sessions where the user can wait:

1. Call start_research
2. Poll get_status every 10-30 seconds
3. When state == "completed", call get_result
4. Present the report to the user

Async (fire-and-forget with follow-up)

For background processing:

1. Call start_research, return the research_id to the user
2. User can check status later with get_status --research_id <id>
3. When ready, call get_result to fetch the complete report

Chained workflows

After research completes:

1. Call get_result to get sources
2. Pass sources to other skills (e.g., markdown-converter, summarize)
3. Build RAG indexes or knowledge bases from the sources

Error Handling

start_research failures

• HTTP/network errors — Retry with exponential backoff (3 attempts)
• LDR validation errors — Return error to user (bad query, invalid params)
• Auth failures — Check credentials, return clear error

get_status / get_result failures

• Temporarily unavailable — Retry 2-3 times before surfacing error
• Research not found — Return "unknown research_id" error
• Timeout — Return state with timeout reason

Timeouts

• Per HTTP request — 30-60 seconds (configurable)
• Total research duration — No client-side limit (LDR manages this)
• Status polling interval — 10-30 seconds recommended

Example Session

text

User: "Research the latest developments in quantum computing"

Assistant: Starting deep research with LDR...
→ start_research(query="latest developments in quantum computing", mode="detailed")
→ Returns: research_id="abc-123", status="queued"

Assistant: Research started (ID: abc-123). This will take ~5-10 minutes.
I'll check the progress and let you know when it's complete.

[After polling...]

Assistant: Research complete! Here's what I found:

## Summary
[summary from get_result]

## Full Report
[report_markdown from get_result]

## Sources (12 found)
1. [Source 1 title](url)
2. [Source 2 title](url)
...

Troubleshooting

LDR service not responding

1. Check LDR_BASE_URL is correct
2. Verify LDR service is running: curl http://127.0.0.1:5000/health
3. Check LDR logs for errors

Authentication failures

1. Ensure credentials are set via env or local .env only (e.g. LDR_SERVICE_USER, LDR_SERVICE_PASSWORD), not in committed config.
2. LDR uses session + CSRF (not Basic Auth). The script GETs the login page, extracts the CSRF token, then POSTs the login form. If LDR uses a different login path or field names, set LDR_LOGIN_URL or see the script’s login section.
3. Test: run the script with credentials set and check for "Login successful"; or open LDR_LOGIN_URL in a browser and sign in there to verify LDR is up.

Research stuck in "running" state

1. Check LDR service health
2. Review LDR logs for stuck jobs
3. Consider timeout and restart if >30 minutes with no progress
