parallel-web/parallel-agent-skills

CLI-backed web search with JSON output and keyword filtering.

What is parallel-web-search?

A command-line web search skill that executes queries via parallel-cli and saves results to JSON. Use it when you need explicit CLI control, JSON output for follow-up analysis, or when the Parallel Search MCP tool is unavailable.

  • Execute web searches with natural-language objectives and keyword queries
  • Save full results to JSON files for downstream processing
  • Filter results by date range, domain inclusion/exclusion, and geographic location
  • Choose search modes (turbo, fast, advanced, basic) based on query complexity
  • Group related searches using session IDs for multi-step research
  • Limit result count and excerpt length to control output size

How to install parallel-web-search

How to use parallel-web-search

  1. 1.Choose a short, descriptive filename in lowercase with hyphens (e.g., react-19-features)
  2. 2.Run parallel-cli search with your query objective and optional -q keyword flags
  3. 3.Add --json and -o /tmp/$FILENAME.json to save results
  4. 4.Parse the JSON output file to extract title, url, publish_date, and excerpts
  5. 5.Cite every fact inline using [Title](URL) from the JSON results
  6. 6.End your response with a Sources section listing all URLs and dates

Use cases

Good for
  • Finding current information on a topic and saving results for analysis
  • Comparing multiple sources on a specific question with keyword filtering
  • Searching within trusted domains only to reduce noise
  • Time-sensitive lookups requiring results within a specific date range
  • Multi-step research where session IDs link related searches together
Who it's for
  • Developers building agents that need programmatic search output
  • Researchers requiring structured JSON results for further processing
  • Users who prefer CLI-only controls over MCP tool integrations
  • Anyone needing geo-targeted or domain-filtered search results

parallel-web-search FAQ

When should I use this skill instead of the Parallel Search MCP tool?

Use this skill when you explicitly need CLI control, JSON file output for follow-up questions, or when the bundled Parallel Search MCP is unavailable. For ordinary lookups and current-information queries, prefer the web_search MCP tool.

What does the -q flag do?

The -q flag adds specific keyword queries to supplement your main objective. Use multiple -q flags to search for related terms alongside your primary natural-language query.

How do I limit results to specific websites?

Use --include-domains domain1.com,domain2.com to search only those sources, or --exclude-domains domain.com to filter out noisy sites.

What search modes are available and when should I use them?

Use --mode turbo for simple fact lookups (fastest), --mode fast for high-quality results within ~1 second, --mode advanced for multi-step agentic searches, or keep the default basic mode for most queries.

How do I group related searches together?

If a prior search response returns a session_id, pass it to the next search using --session-id "<returned-session-id>" to link them for multi-step research.

Web Search

Search the web for: $ARGUMENTS

Command

Choose a short, descriptive filename based on the query (e.g., ai-chip-news, react-vs-vue). Use lowercase with hyphens, no spaces. Substitute it into the command inline — $FILENAME and <keyword> below are placeholders, not shell variables; do not copy them verbatim.

parallel-cli search "$ARGUMENTS" -q "<keyword1>" -q "<keyword2>" --json --max-results 10 --excerpt-max-chars-total 27000 -o "/tmp/$FILENAME.json"

Concrete example for a query about React 19:

parallel-cli search "latest React 19 features and adoption" -q "React 19" -q "concurrent rendering" --json --max-results 10 --excerpt-max-chars-total 27000 -o "/tmp/react-19-features.json"

The first argument is the objective — a natural language description of what you're looking for. It replaces multiple keyword searches with a single call for broad or complex queries. Add -q flags for specific keyword queries to supplement the objective. The -o flag saves the full results to a JSON file for follow-up questions.

Options if needed:

  • --after-date YYYY-MM-DD for time-sensitive queries
  • --include-domains domain1.com,domain2.com to limit to specific sources
  • --exclude-domains domain.com to filter out noisy sources
  • --mode turbo for simple fact lookups where speed matters most; supports English and Japanese queries
  • --mode fast for high-quality search within an approximately one-second latency budget; requires CLI ≥ 0.9.2, and latency is not guaranteed
  • --mode advanced for harder questions (multi-step, agentic search). Keep the default basic unless the request needs another mode
  • --location us (ISO 3166-1 alpha-2) for geo-targeted results
  • --session-id "<returned-session-id>" to group related Search/Extract calls when a prior response returned one. A session_id or search_id is not a Task interaction ID or research run ID; never send it to research status/poll or --previous-interaction-id

Parsing results

Read the saved -o JSON file as the authoritative payload. Result and excerpt limits bound requested content, but stdout can still exceed the tool's output limit. Truncated stdout is not parseable JSON and is not proof of incomplete saved results. Inspect an existing output path before using it because Search overwrites that file. For each result, extract:

  • title, url, and publish_date if provided; omit unknown dates
  • Useful content from excerpts (skip navigation noise like menus, footers, "Skip to content")

Check the exit status, returned API error and warnings before presenting results. On an error or empty results, report what happened and do not fabricate an answer. An old output file is not evidence that a failed request succeeded. For sparse results, state the coverage limits; refine the objective or queries only when useful for the user's request.

Response format

CRITICAL: Every claim must have an inline citation. Use markdown links like Title pulling only from the JSON output. Never invent or guess URLs.

Synthesize a response that:

  • Leads with the key answer/finding
  • Includes specific facts, names, numbers, dates
  • Cites every fact inline as Source Title — do not leave any claim uncited
  • Organizes by theme if multiple topics

End with a Sources section listing every URL referenced:

Sources:
- [Source Title](https://example.com/article) (Feb 2026)
- [Another Source](https://example.com/other) (Jan 2026)

This Sources section is mandatory. Do not omit it.

Only include source dates that were returned or verified in the retrieved content. Leave the date out when unknown.

After the Sources section, mention the output file path (/tmp/$FILENAME.json) so the user knows it's available for follow-up questions.

Setup

If parallel-cli is not found, install and authenticate:

/parallel:parallel-cli-setup

If a documented command or option is missing, check the installed version and upgrade through its installation method: standalone parallel-cli update, pipx pipx upgrade parallel-web-tools, uv uv tool upgrade parallel-web-tools, Homebrew brew upgrade parallel-web/tap/parallel-cli, or npm npm update -g parallel-web-cli. Verify help in the same terminal before retrying.

For authentication errors, inspect parallel-cli auth --json and its authenticated boolean; exit zero alone does not prove authentication. A 403 can indicate permissions, policy or billing. Report the actual error; check balance only for a billing-specific failure and never add funds without explicit confirmation.
