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?

Annotations indicate readOnlyHint=false and idempotentHint=true, but the description adds critical behavioral details: OAuth requirement, subscription-id return, SMS verification and 10/day cap, and webhook auto-disable after consecutive failures (in delivery schema description). These exceed the annotations and accurately describe side effects without contradiction.

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 main description is dense but well-organized: purpose, return, auth prerequisite, supported types, delivery channels. Each sentence carries useful information and no filler. The schema's delivery description is also thorough, though slightly long. Overall, efficient and structured.

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?

For a tool with nested objects, enums, and no output schema, the description is remarkably complete: it covers required auth, return value, type-specific parameter patterns, delivery options and their constraints (including webhook signature handling in the schema). The only minor gap is that webhook is not mentioned in the main description, but it is fully covered in the schema, which the agent will see.

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 coverage is 100%, but the description enriches semantics with concrete examples per type (e.g., items:['5.02'] = officer change, topic:'fed', series_id:'UNRATE') and clarifies the 'feed always on' behavior for delivery. This adds value beyond the baseline structured schema.

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 opens with 'Create a proactive monitoring subscription to a live-data event stream' — a specific verb and resource. It also states the return value ('Returns the new subscription id'), clearly distinguishing this creation tool from siblings like list_subscriptions and unsubscribe.

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?

The description provides clear context for use: requires a Pipeworx OAuth account, distinguishes delivery channels (always-on feed vs optional email/sms), and implicitly contrasts with recent_alerts by noting the feed can be pulled via that tool. It lacks explicit when/when-not statements but gives sufficient conditions and prerequisites.

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

A4/5.0
Disambiguation3/5

Most tools have clearly distinct purposes, but there are overlapping clusters: the three ask_pipeworx variants and multiple polymarket analysis tools can cause selection ambiguity. Descriptions help, yet boundaries between entity_profile, compare_entities, recent_changes, and ask_pipeworx require careful reading.

Naming Consistency4/5

Tool names almost all follow snake_case with verb-noun or verb-phrase structure (ask_pipeworx, validate_isin, list_subscriptions), and family prefixes like ask_pipeworx_* and polymarket_* are consistent. Minor deviations include one-word verbs (remember, recall, forget) and adjective-noun names (recent_alerts, recent_changes, entity_profile).

Tool Count2/5

With 34 tools, the surface is well above the 25-tool threshold that typically feels heavy, even though the Pipeworx platform is broad in scope. The server named 'Isin' exposes a large toolkit far beyond its apparent identifier-focused purpose, making the count feel excessive.

Completeness4/5

The broader data-access, research, subscription, and utility workflows are well covered, including discovery, grounded queries, entity profiles, comparisons, and claim validation. Minor gaps include the lack of direct pipeworx:// URI reading and ISIN issuer resolution, but agents can work around these.
