# Parallel — Printing Press CLI ## Prerequisites: Install the CLI This skill drives the `parallel-pp-cli` binary. **You must verify the CLI is installed before invoking any command from this skill.** If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to `$HOME/.local/bin` on macOS/Linux and `%LOCALAPPDATA%\Programs\PrintingPress\bin` on Windows: ```bash npx -y @mvanhorn/printing-press-library install parallel --cli-only ``` 2. Verify: `parallel-pp-cli --version` 3. Ensure the reported install directory is on `$PATH` for the agent/runtime that will invoke this skill. If the `npx` install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.5 or newer). This installs into `$GOPATH/bin` (default `$HOME/go/bin`), so add that directory to `$PATH` instead: ```bash go install github.com/mvanhorn/printing-press-library/library/ai/parallel/cmd/parallel-pp-cli@latest ``` If `--version` reports "command not found" after install, the runtime cannot see the binary directory on `$PATH`. Do not proceed with skill commands until verification succeeds. Search, extract, deep research, FindAll, monitors, and Account balance/apps/keys in one Go binary. Session stitch, research recall, and monitor digests compound every run into offline memory. Product API key auth stays separate from Account OAuth so headline search never requires a dashboard login. ## When to Use This CLI Use this CLI for agent-native Parallel web research loops, offline recall of past searches/runs, FindAll-to-enrichment pipelines, monitor digests, and dual-auth Account admin. Prefer official parallel-cli when you need its YAML enrich planner or DuckDB/BigQuery deploy integrations. ## Anti-triggers Do not use this CLI for: - Do not use this CLI as a general web browser or scraper outside Parallel APIs - Do not use Account balance add for large unattended spends without reviewing idempotency keys - Do not prefer this over Parallel Search MCP for one-off free anonymous search experiments ## Unique Capabilities These capabilities aren't available in any other tool for this API. ### Local state that compounds - **`session stitch`** — Bind search, extract, and task/findall runs into one local session chain for agent resume. _Use when an agent needs to resume a multi-step Parallel research loop without re-fetching._ ```bash parallel-pp-cli session stitch --search-id search_demo --json --agent ``` - **`monitors digest`** — Mechanical per-monitor event counts and top titles since a duration window. _Use for Monday triage of which monitors fired or went quiet._ ```bash parallel-pp-cli monitors digest --since 7d --json --agent ``` - **`research recall`** — FTS across local searches, extracts, and task summaries with typed hit IDs. _Use before paying for a live search when prior local research may already answer._ ```bash parallel-pp-cli research recall --query "Anthropic funding" --json --agent --select hits.source,hits.id,hits.title ``` ### Spend control - **`tasks guard`** — Refuse Task creates when prepaid balance is below a threshold. _Use before expensive Task Groups when you must avoid surprise credit burn._ ```bash parallel-pp-cli tasks guard --min-balance 500 --dry-run --json --agent ``` - **`balance burn`** — Diff local balance snapshots against local run volume over a window. _Use when explaining weekly credit burn without opening the dashboard._ ```bash parallel-pp-cli balance burn --since 7d --json --agent ``` ### Research pipelines - **`findall promote`** — Turn FindAll candidates into a Task Group enrichment job. _Use when entity discovery should immediately become batch enrichment._ ```bash parallel-pp-cli findall promote --findall-id findall_demo --limit 10 --json --agent ``` - **`tasks lineage`** — Print the offline previous_interaction_id follow-up chain for a run. _Use when debugging multi-turn deep research context chains offline._ ```bash parallel-pp-cli tasks lineage trun_demo --json --agent ``` ## Command Reference **chat** — Manage chat - `parallel-pp-cli chat` — Chat completions. This endpoint can be used to get realtime chat completions. **extract** — Extract returns excerpts or full content from one or more URLs. Inputs are a list of URLs and an optional search objective and keyword queries. The returned excerpts or full content is formatted as markdown and suitable for LLM consumption. - Result: excerpts or full content from the URL formatted as markdown - `parallel-pp-cli extract` — Extracts relevant content from specific web URLs. **findall** — The FindAll API discovers and evaluates entities that match complex criteria from natural language objectives. Submit a high-level goal and the service automatically generates structured match conditions, discovers relevant candidates, and evaluates each against the criteria. Returns comprehensive results with detailed reasoning, citations, and confidence scores for each match decision. Streaming events and webhooks are supported. - `parallel-pp-cli findall cancel-run` — Cancel a FindAll run. - `parallel-pp-cli findall enrich-run` — Add an enrichment to a FindAll run. - `parallel-pp-cli findall entity-search` — Return ranked entities matching a natural language objective. - `parallel-pp-cli findall extend-run` — Extend a FindAll run by adding additional matches to the current match limit. - `parallel-pp-cli findall get-events` — Stream events from a FindAll run. - `parallel-pp-cli findall get-result` — Retrieve the FindAll run result at the time of the request. - `parallel-pp-cli findall get-schema` — Get FindAll Run Schema - `parallel-pp-cli findall ingest-run` — Transforms a natural language search objective into a structured FindAll spec. - `parallel-pp-cli findall runs-v1` — Starts a FindAll run. This endpoint immediately returns a FindAll run object with status set to 'queued'. - `parallel-pp-cli findall runs-v1-get` — Retrieve FindAll Run Status **monitors** — The Monitor API watches the web for material changes on a fixed frequency. Each monitor runs once on creation and then on its configured schedule, emitting events when meaningful changes are detected. - `event_stream` monitors track a search query and emit an event for each new material change. - `snapshot` monitors track a specific task run's output and emit an event when the output changes. Results can be polled via the events endpoint or delivered via webhooks. - `parallel-pp-cli monitors create` — Create a monitor. Monitors run on a fixed frequency to detect material changes in web content. - `parallel-pp-cli monitors list` — List monitors ordered by creation time, newest first. Monitors are sorted by `created_at` descending. - `parallel-pp-cli monitors retrieve` — Retrieve a monitor. Retrieves a specific monitor by `monitor_id`. **service** — Service utility endpoints - `parallel-pp-cli service account-add-balance` — Charge the organization's default payment method and add the amount to the prepaid credit balance. - `parallel-pp-cli service account-create-app` — Create a new app for the authenticated organization - `parallel-pp-cli service account-create-key` — Create a new API key for an app - `parallel-pp-cli service account-delete-app` — Delete an app from the authenticated organization - `parallel-pp-cli service account-delete-key` — Delete an API key from an app - `parallel-pp-cli service account-get-balance` — Get the authenticated organization's prepaid credit balance - `parallel-pp-cli service account-list-apps` — List all apps for the authenticated organization **tasks** — The Task API executes web research and extraction tasks. Clients submit a natural-language objective with an optional input schema; the service plans retrieval, fetches relevant URLs, and returns outputs that conform to a provided or inferred JSON schema. Supports deep research style queries and can return rich structured JSON outputs. Processors trade-off between cost, latency, and quality. Each processor supports calibrated confidences. - Output metadata: citations, excerpts, reasoning, and confidence per field Task Groups enable batch execution of many independent Task runs with group-level monitoring and failure handling. - Submit hundreds or thousands of Tasks as a single group - Observe group progress and receive results as they complete - Real-time updates via Server-Sent Events (SSE) - Add tasks to an existing group while it is running - Group-level retry and error aggregation - `parallel-pp-cli tasks runs-events-get` — Streams events for a task run. Returns a stream of events showing progress updates and state changes for the task run. - `parallel-pp-cli tasks runs-events-get-runs` — Streams events for a task run. Returns a stream of events showing progress updates and state changes for the task run. - `parallel-pp-cli tasks runs-get` — Retrieves run status by run_id. The run result is available from the `/result` endpoint. - `parallel-pp-cli tasks runs-input-get` — Retrieves the input of a run by run_id. - `parallel-pp-cli tasks runs-post` — Initiates a task run. Returns immediately with a run object in status 'queued'. - `parallel-pp-cli tasks runs-result-get` — Retrieves a run result by run_id, blocking until the run is completed. - `parallel-pp-cli tasks sessions-events-get` — Streams events from a TaskGroup: status updates and run completions. - `parallel-pp-cli tasks taskgroups-get` — Retrieves aggregated status across runs in a TaskGroup. - `parallel-pp-cli tasks taskgroups-post` — Initiates a TaskGroup to group and track multiple runs. - `parallel-pp-cli tasks taskgroups-runs-get` — Retrieves task runs in a TaskGroup and optionally their inputs and outputs. - `parallel-pp-cli tasks taskgroups-runs-id-get` — Retrieves run status by run_id. - `parallel-pp-cli tasks taskgroups-runs-post` — Initiates multiple task runs within a TaskGroup. **websearch** — Manage websearch - `parallel-pp-cli websearch` — Searches the web. The legacy Search API reference (`/v1beta/search` endpoint) is available [here](https://docs.parallel. ### Finding the right command When you know what you want to do but not which command does it, ask the CLI directly: ```bash parallel-pp-cli which "<capability in your own words>" ``` `which` resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code `0` means at least one match; exit code `2` means no confident match — fall back to `--help` or use a narrower query. ## Recipes ### Doctor before spend ```bash parallel-pp-cli doctor --dry-run ``` Confirm auth wiring without calling paid endpoints ### Recall then decide ```bash parallel-pp-cli research recall "Anthropic" --json --agent --select hits.source,hits.id,hits.title ``` Check local memory before paying for live Search ### Monitor weekly digest ```bash parallel-pp-cli monitors digest --since 7d --json --agent ``` Mechanical triage of monitor events ### Promote FindAll to enrichment ```bash parallel-pp-cli findall promote --findall-id findall_demo --limit 5 --json --agent ``` Entity discovery into Task Group ### Balance burn check ```bash parallel-pp-cli balance burn --since 7d --json --agent ``` Explain weekly credit burn from local snapshots ## Auth Setup Product commands use PARALLEL_API_KEY via the x-api-key header. Account commands (balance, apps, keys) need an OAuth device-flow Bearer JWT (see docs.parallel.ai/integrations/account-api); a Product API key alone cannot call Account endpoints. Never commit API key values. Run `parallel-pp-cli doctor` to verify setup. ## Agent Mode Add `--agent` to any command. Expands to: `--json --compact --no-input --no-color --yes`. - **Pipeable** — JSON on stdout, errors on stderr - **Filterable** — `--select` keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs: ```bash parallel-pp-cli monitors list --agent --select id,name,status ``` - **Previewable** — `--dry-run` shows the request without sending - **Offline-friendly** — sync/search commands can use the local SQLite store when available - **Non-interactive** — never prompts, every input is a flag - **Explicit retries** — use `--idempotent` only when an already-existing create should count as success, and use `--ignore-missing` only when a missing delete target should count as success ### Response envelope Commands that read from the local store or the API wrap output in a provenance envelope: ```json { "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."}, "results": <data> } ``` Parse `.results` for data and `.meta.source` to know whether it's live or local. A human-readable `N results (live)` summary is printed to stderr only when stdout is a terminal AND no machine-format flag (`--json`, `--csv`, `--compact`, `--quiet`, `--plain`, `--select`) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout. ## Paths and state Agents should treat the CLI's path resolver as part of the runtime contract: - Use `--home <dir>` for one invocation, or set `PARALLEL_HOME=<dir>` to relocate all four path kinds under one root. - Use per-kind env vars only when a specific kind must diverge: `PARALLEL_CONFIG_DIR`, `PARALLEL_DATA_DIR`, `PARALLEL_STATE_DIR`, `PARALLEL_CACHE_DIR`. - Resolution order is per-kind env var, `--home`, `PARALLEL_HOME`, XDG (`XDG_CONFIG_HOME`, `XDG_DATA_HOME`, `XDG_STATE_HOME`, `XDG_CACHE_HOME`), then platform defaults. - `config` contains settings like `config.toml` and profiles. `data` contains `credentials.toml`, `data.db`, cookies, and auth sidecars. `state` contains persisted queries, jobs, and `teach.log`. `cache` contains regenerable HTTP/cache files. - Stored secrets live in `credentials.toml` under the data dir. Existing legacy `config.toml` secrets are read for compatibility and leave `config.toml` on the first auth write. - Run `parallel-pp-cli doctor --fail-on warn` to surface path and credential-location warnings. `agent-context` exposes a schema v4 `paths` block for agents that need the resolved dirs. - For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags: ```json { "mcpServers": { "parallel": { "command": "parallel-pp-mcp", "env": { "PARALLEL_HOME": "/srv/parallel" } } } } ``` Fleet precedence: an inherited per-kind env var overrides an explicit `--home` for that kind. Use `PARALLEL_HOME` or per-kind vars as durable fleet levers, and use `--home` only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing `PARALLEL_HOME`, or `doctor` will not find credentials left under the former root. ## Automatic learning This CLI ships a self-capturing learning loop. The CLI does its own bookkeeping: every invocation is journaled locally, a failed flag followed by a corrected retry auto-derives a `flag_alias` candidate, and a `teach` on a query family without a playbook auto-synthesizes a `playbook_candidate` from the session's journal. Your job is judgment only: `recall` first, act on surfaced candidates, `teach` the final answer, `playbook amend` when you observe a correction. You never record failures by hand. ### Step 1: `recall` before any discovery Before list/search/drill commands on a new user question, run: ```bash parallel-pp-cli recall "<user's question>" --agent ``` The response envelope: ```json { "query": "...", "normalized": "<normalized form>", "query_entities": ["..."], "found": true | false, "match_score": 0.0, "results": [ { "resource_id": "...", "resource_type": "...", "venue": "...", "confidence": 2, "entity_match": "exact|partial|unknown", "source": "taught|preseed|pattern", "warnings": ["..."] } ], "mismatches": [ /* only when --debug-mismatches */ ], "warnings": [ /* top-level */ ], "candidates": [ { "id": 12, "class": "flag_alias | playbook_candidate", "summary": "...", "sightings": 3, "last_seen": "...", "rationale": "...", "next_action": ["<trial command>", "parallel-pp-cli learnings confirm 12"] } ], "playbook": { "query_family": "...", "playbook": { "steps": [ { "cmd": "<command with {slot} substitution>", "purpose": "..." } ], "entity_slots": ["$ENTITY"], "expected_tool_calls": 3 }, "slots_resolved": { "$ENTITY": { "token": "<live token>", "canonical": "<canonical>" } }, "notes": "<workarounds + gotchas for this query family>" }, "notes": "<duplicate surface for non-playbook callers>"
