    +description: Optional vendor skill for Parallel CLI — agent-native web search, extraction, deep research, enrichment, FindAll, and monitoring. Prefer JSON output and non-interactive flows.

    +# Parallel CLI
    +
    +Use `parallel-cli` when the user explicitly wants Parallel, or when a terminal-native workflow would benefit from Parallel's vendor-specific stack for web search, extraction, deep research, enrichment, entity discovery, or monitoring.
    +
    +This is an optional third-party workflow, not a Hermes core capability.
    +
    +Important expectations:
    +- Parallel is a paid service with a free tier, not a fully free local tool.
    +- It overlaps with Hermes native `web_search` / `web_extract`, so do not prefer it by default for ordinary lookups.
    +- Prefer this skill when the user mentions Parallel specifically or needs capabilities like Parallel's enrichment, FindAll, or monitor workflows.
    +
    +`parallel-cli` is designed for agents:
    +- JSON output via `--json`
    +- Non-interactive command execution
    +- Async long-running jobs with `--no-wait`, `status`, and `poll`
    +- Context chaining with `--previous-interaction-id`
    +- Search, extract, research, enrichment, entity discovery, and monitoring in one CLI
    +
    +## When to use it
    +
    +Prefer this skill when:
    +- The user explicitly mentions Parallel or `parallel-cli`
    +- The task needs richer workflows than a simple one-shot search/extract pass
    +- You need async deep research jobs that can be launched and polled later
    +- You need structured enrichment, FindAll entity discovery, or monitoring
    +
    +Prefer Hermes native `web_search` / `web_extract` for quick one-off lookups when Parallel is not specifically requested.
    +
    +## Installation
    +
    +Try the least invasive install path available for the environment.
    +
    +### Homebrew
    +
    +```bash
    +brew install parallel-web/tap/parallel-cli
    +```
    +
    +### npm
    +
    +```bash
    +npm install -g parallel-web-cli
    +```
    +
    +### Python package
    +
    +```bash
    +pip install "parallel-web-tools[cli]"
    +```
    +
    +### Standalone installer
    +
    +```bash
    +curl -fsSL https://parallel.ai/install.sh | bash
    +```
    +
    +If you want an isolated Python install, `pipx` can also work:
    +
    +```bash
    +pipx install "parallel-web-tools[cli]"
    +pipx ensurepath
    +```
    +
    +## Authentication
    +
    +Interactive login:
    +
    +```bash
    +parallel-cli login
    +```
    +
    +Headless / SSH / CI:
    +
    +```bash
    +parallel-cli login --device
    +```
    +
    +API key environment variable:
    +
    +```bash
    +export PARALLEL_API_KEY="***"
    +```
    +
    +Verify current auth status:
    +
    +```bash
    +parallel-cli auth
    +```
    +
    +If auth requires browser interaction, run with `pty=true`.
    +
    +## Core rule set
    +
    +1. Always prefer `--json` when you need machine-readable output.
    +2. Prefer explicit arguments and non-interactive flows.
    +3. For long-running jobs, use `--no-wait` and then `status` / `poll`.
    +4. Cite only URLs returned by the CLI output.
    +5. Save large JSON outputs to a temp file when follow-up questions are likely.
    +6. Use background processes only for genuinely long-running workflows; otherwise run in foreground.
    +7. Prefer Hermes native tools unless the user wants Parallel specifically or needs Parallel-only workflows.
    +
    +## Quick reference

    +```
    +
    +## Common flags and patterns
    +
    +Commonly useful flags:
    +- `--json` for structured output
    +- `--no-wait` for async jobs
    +- `--previous-interaction-id <id>` for follow-up tasks that reuse earlier context
    +- `--max-results <n>` for search result count
    +- `--mode one-shot|agentic` for search behavior
    +- `--include-domains domain1.com,domain2.com`
    +- `--exclude-domains domain1.com,domain2.com`
    +- `--after-date YYYY-MM-DD`
    +
    +Read from stdin when convenient:
    +
    +```bash
    +echo "What is the latest funding for Anthropic?" | parallel-cli search - --json
    +echo "Research question" | parallel-cli research run - --json
    +```
    +
    +## Search
    +
    +Use for current web lookups with structured results.
    +
    +```bash
    +parallel-cli search "What is Anthropic's latest AI model?" --json
    +parallel-cli search "SEC filings for Apple" --include-domains sec.gov --json
    +parallel-cli search "bitcoin price" --after-date 2026-01-01 --max-results 10 --json
    +parallel-cli search "latest browser benchmarks" --mode one-shot --json
    +parallel-cli search "AI coding agent enterprise reviews" --mode agentic --json
    +```
    +
    +Useful constraints:
    +- `--include-domains` to narrow trusted sources
    +- `--exclude-domains` to strip noisy domains
    +- `--after-date` for recency filtering
    +- `--max-results` when you need broader coverage
    +
    +If you expect follow-up questions, save output:
    +
    +```bash
    +parallel-cli search "latest React 19 changes" --json -o /tmp/react-19-search.json
    +```
    +
    +When summarizing results:
    +- lead with the answer
    +- include dates, names, and concrete facts
    +- cite only returned sources
    +- avoid inventing URLs or source titles
    +
    +## Extraction
    +
    +Use to pull clean content or markdown from a URL.
    +
    +```bash
    +parallel-cli extract https://example.com --json
    +parallel-cli extract https://company.com --objective "Find pricing info" --json
    +parallel-cli extract https://example.com --full-content --json
    +parallel-cli fetch https://example.com --json
    +```
    +
    +Use `--objective` when the page is broad and you only need one slice of information.
    +
    +## Deep research
    +
    +Use for deeper multi-step research tasks that may take time.
    +
    +Common processor tiers:
    +- `lite` / `base` for faster, cheaper passes
    +- `core` / `pro` for more thorough synthesis
    +- `ultra` for the heaviest research jobs
    +
    +### Synchronous
    +
    +```bash
    +parallel-cli research run \
    +  "Compare the leading AI coding agents by pricing, model support, and enterprise controls" \
    +  --processor core \
    +  --json
    +```
    +
    +### Async launch + poll
    +
    +```bash
    +parallel-cli research run \
    +  "Compare the leading AI coding agents by pricing, model support, and enterprise controls" \
    +  --processor ultra \
    +  --no-wait \
    +  --json
    +
    +parallel-cli research status trun_xxx --json
    +parallel-cli research poll trun_xxx --json
    +parallel-cli research processors --json
    +```
    +
    +### Context chaining / follow-up
    +
    +```bash
    +parallel-cli research run "What are the top AI coding agents?" --json
    +parallel-cli research run \
    +  "What enterprise controls does the top-ranked one offer?" \
    +  --previous-interaction-id trun_xxx \
    +  --json
    +```
    +
    +Recommended Hermes workflow:
    +1. launch with `--no-wait --json`
    +2. capture the returned run/task ID
    +3. if the user wants to continue other work, keep moving
    +4. later call `status` or `poll`
    +5. summarize the final report with citations from the returned sources
    +
    +## Enrichment
    +
    +Use when the user has CSV/JSON/tabular inputs and wants additional columns inferred from web research.
    +
    +### Suggest columns
    +
    +```bash
    +parallel-cli enrich suggest "Find the CEO and annual revenue" --json
    +```
    +
    +### Plan a config
    +
    +```bash
    +parallel-cli enrich plan -o config.yaml
    +```
    +
    +### Inline data
    +
    +```bash
    +parallel-cli enrich run \
    +  --data '[{"company": "Anthropic"}, {"company": "Mistral"}]' \
    +  --intent "Find headquarters and employee count" \
    +  --json
    +```
    +
    +### Non-interactive file run
    +
    +```bash
    +parallel-cli enrich run \
    +  --source-type csv \
    +  --source companies.csv \
    +  --target enriched.csv \
    +  --source-columns '[{"name": "company", "description": "Company name"}]' \
    +  --intent "Find the CEO and annual revenue"
    +```
    +
    +### YAML config run
    +
    +```bash
    +parallel-cli enrich run config.yaml
    +```
    +
    +### Status / polling
    +
    +```bash
    +parallel-cli enrich status <task_group_id> --json
    +parallel-cli enrich poll <task_group_id> --json
    +```
    +
    +Use explicit JSON arrays for column definitions when operating non-interactively.
    +Validate the output file before reporting success.
    +
    +## FindAll
    +
    +Use for web-scale entity discovery when the user wants a discovered dataset rather than a short answer.
    +
    +```bash
    +parallel-cli findall run "Find AI coding agent startups with enterprise offerings" --json
    +parallel-cli findall run "AI startups in healthcare" -n 25 --json
    +parallel-cli findall status <run_id> --json
    +parallel-cli findall poll <run_id> --json
    +parallel-cli findall result <run_id> --json
    +parallel-cli findall schema <run_id> --json
    +```
    +
    +This is a better fit than ordinary search when the user wants a discovered set of entities that can be reviewed, filtered, or enriched later.
    +
    +## Monitor
    +
    +Use for ongoing change detection over time.
    +
    +```bash
    +parallel-cli monitor list --json
    +parallel-cli monitor get <monitor_id> --json
    +parallel-cli monitor events <monitor_id> --json
    +parallel-cli monitor delete <monitor_id> --json
    +```
    +
    +Creation is usually the sensitive part because cadence and delivery matter:
    +
    +```bash
    +parallel-cli monitor create --help
    +```
    +
    +Use this when the user wants recurring tracking of a page or source rather than a one-time fetch.
    +
    +## Recommended Hermes usage patterns
    +
    +### Fast answer with citations
    +1. Run `parallel-cli search ... --json`
    +2. Parse titles, URLs, dates, excerpts
    +3. Summarize with inline citations from the returned URLs only
    +
    +### URL investigation
    +1. Run `parallel-cli extract URL --json`
    +2. If needed, rerun with `--objective` or `--full-content`
    +3. Quote or summarize the extracted markdown
    +
    +### Long research workflow
    +1. Run `parallel-cli research run ... --no-wait --json`
    +2. Store the returned ID
    +3. Continue other work or periodically poll
    +4. Summarize the final report with citations
    +
    +### Structured enrichment workflow
    +1. Inspect the input file and columns
    +2. Use `enrich suggest` or provide explicit enriched columns
    +3. Run `enrich run`
    +4. Poll for completion if needed
    +5. Validate the output file before reporting success
    +
    +## Error handling and exit codes
    +
    +The CLI documents these exit codes:
    +- `0` success
    +- `2` bad input
    +- `3` auth error
    +- `4` API error
    +- `5` timeout
    +
    +If you hit auth errors:
    +1. check `parallel-cli auth`
    +2. confirm `PARALLEL_API_KEY` or run `parallel-cli login` / `parallel-cli login --device`
    +3. verify `parallel-cli` is on `PATH`
    +
    +## Maintenance
    +
    +Check current auth / install state:
    +
    +```bash
    +parallel-cli auth
    +parallel-cli --help
    +```
    +
    +Update commands:
    +
    +```bash
    +parallel-cli update
    +pip install --upgrade parallel-web-tools
    +parallel-cli config auto-update-check off
    +```
    +
    +## Pitfalls
    +
    +- Do not omit `--json` unless the user explicitly wants human-formatted output.
    +- Do not cite sources not present in the CLI output.
    +- `login` may require PTY/browser interaction.
    +- Prefer foreground execution for short tasks; do not overuse background processes.
    +- For large result sets, save JSON to `/tmp/*.json` instead of stuffing everything into context.
    +- Do not silently choose Parallel when Hermes native tools are already sufficient.
    +- Remember this is a vendor workflow that usually requires account auth and paid usage beyond the free tier.
