Subscribe to Alerts

subscribe
Idempotent

Create a proactive monitoring subscription to a live-data event stream. Returns the new subscription id. Requires a Pipeworx OAuth account (anonymous + BYO cannot persist subscriptions). Supported types: "sec_8k" (8-K filings matching ticker + item codes — e.g. items:["5.02"] = officer change), "polymarket_edge" (Polymarket↔Kalshi cross-venue mispricings — params:{topic:"fed"}), "fred_series" (new FRED observations — params:{series_id:"UNRATE"}). Delivery channels: feed (always on — pull via recent_alerts or GET registry.pipeworx.io/alerts.json), and optionally email (set delivery:{email:"you@x.com"}) or sms (delivery:{sms:"+15551234567"} — phone must be verified at /account first; 10/day cap).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
typeYesSubscription type.
paramsYesType-specific filter. sec_8k: {ticker:"AAPL", items?:["5.02","1.01"]}. polymarket_edge: {topic:"fed", min_spread_bps?:500}. fred_series: {series_id:"UNRATE"}. patent_grant: {applicant:"Apple Inc."}. clinical_trial: {sponsor?:"Pfizer", condition?:"lung cancer", phase?:"PHASE3"} (sponsor or condition required).
deliveryNoOptional delivery channels in addition to the always-on persistent feed. {email:"you@x.com"} sends a templated alert per fired event. {sms:"+15551234567"} sends an SMS per event — must match the verified phone on the caller's account (verify at https://pipeworx.io/account first; 10/day cap). {webhook:"https://..."} POSTs each event JSON to your endpoint, HMAC-signed — the response includes delivery.webhook_secret (whsec_…) ONCE; verify X-Pipeworx-Signature = sha256 HMAC of "<X-Pipeworx-Timestamp>.<raw body>". Auto-disabled after 10 consecutive failing runs.

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds substantial behavioral context beyond the annotations: it requires a Pipeworx OAuth account, returns a subscription id, explains each subscription type and delivery channel in detail, notes SMS phone verification and caps, and discloses webhook signing behavior and auto-disable after failures. It does not contradict any annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense but each sentence contributes useful information, including prerequisites, supported types, and delivery channels. It is front-loaded with the core action and return value. Some redundancy with the schema's delivery details is present but not excessive for a complex tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a complex subscription tool with nested params, multiple types, and no output schema. The description covers the return value, account requirements, type-specific parameters, delivery channel options, constraints, and failure behavior. Combined with the fully described input schema, it is complete enough for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already defines parameters well. The description adds concrete examples for each type (e.g., items:["5.02"]) and detailed delivery semantics, but some of this duplicates the schema's property descriptions. It adds meaningful value without being strictly necessary.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource: 'Create a proactive monitoring subscription to a live-data event stream.' It clearly states it returns the new subscription id, and the mention of subscription creation distinguishes it from sibling tools like list_subscriptions, unsubscribe, and recent_alerts.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear context by listing supported subscription types, required OAuth account, and optional delivery channels. It does not explicitly state when to avoid this tool or compare it to alternatives like list_subscriptions, but the usage boundaries are reasonably clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.7/5.0
Disambiguation2/5

Several tools occupy nearly the same question-answering role: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, and validate_claim all accept natural-language factual queries, and ask_pipeworx_beta is explicitly identical to ask_pipeworx today. The polymarket_* family also has overlapping opportunity-detection responsibilities, so an agent can easily select a near-duplicate tool for the same intent.

Naming Consistency4/5

Tool names are uniformly lowercase snake_case and use recognizable domain prefixes like ask_pipeworx_, polymarket_, datalastic_, and pipeworx_, which makes the set easy to group. The main deviation is that some names are verb-first (ask, compare, subscribe) while others are noun phrases (entity_profile, recent_alerts, bet_research), but this is minor and readable.

Tool Count2/5

At 33 tools this exceeds the 25+ threshold for a single server, and many of them are meta-tools or overlapping research/opportunity scanners that could be consolidated. The breadth is justified only partially; several utilities like generate_llms_txt and scan_dependency feel bolted on.

Completeness3/5

As a general research and monitoring toolkit it covers the full life cycle: discover, ask, verify, compare, profile, cite, remember, subscribe, and alert. But the server is named Datalastic yet the maritime surface is thin (only live position and radius lookup, no historical tracking, port calls, or fleet tools), and a few one-off utilities don't fit a coherent domain.
