Recent Alerts

recent_alerts
Read-onlyIdempotent

Pull fired events from your subscription feed. Returns the most recent alerts the evaluator has written to your persisted feed — each carries source, citation_uri (pipeworx:// when available), and the raw event payload. Filter by type (e.g. "sec_8k") and/or since (ISO timestamp). Set mark_read:true to flag returned events read so the next call only shows newer ones. Polls work fine; the same feed is also at GET registry.pipeworx.io/alerts.json for scripts and dashboards.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
typeNoOptional — filter to one subscription type.
limitNoMax events to return (1-200, default 50).
sinceNoOptional ISO timestamp — return events fired_at >= this time.
mark_readNoFlag the returned events read in the same call (default false).
unread_onlyNoReturn only events where read_at is null (default false).

A4.5/5.0
Behavior4/5

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

Annotations declare readOnly, idempotent, non-destructive. Description adds behavioral details: mark_read flags events as read, iso timestamp format, returned fields (source, citation_uri, raw payload). No contradiction.

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

Conciseness5/5

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

Five focused sentences, front-loaded with main action. Every sentence adds value. No unnecessary words.

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?

Covers return fields, filter options, mark_read behavior, polling suitability, and alternative access. All essential info for a 5-param read-only tool with no output schema.

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 100% with param descriptions. Description adds meaning: example type 'sec_8k', effect of mark_read, and that since expects ISO timestamp. Exceeds baseline 3.

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?

Clearly states 'Pull fired events from your subscription feed. Returns the most recent alerts...' Verb 'pull' and resource 'fired events' are specific. No sibling tool directly overlaps, making differentiation natural.

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?

Provides context for usage: 'Polls work fine' and mentions alternative access via HTTP endpoint. However, lacks explicit when-to-use vs siblings like list_subscriptions or subscribe.

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

A3.8/5.0
Disambiguation2/5

The tool set mixes three distinct domains: BookBrainz entity access (browse, lookup, search), Pipeworx data routing (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, discover_tools, suggest_questions), and Polymarket betting analysis. Multiple tools have overlapping purposes, particularly the ask_pipeworx variants and the various polymarket_* tools, which an agent could easily confuse.

Naming Consistency4/5

All tool names follow a readable snake_case convention. While some are single verbs (browse, lookup, search), others use compound patterns (ask_pipeworx_grounded, polymarket_edge_tracker, pipeworx_trending), and there are a few noun-first names (entity_profile, pipeworx_feedback, recent_changes). The inconsistency is minor and does not hinder readability.

Tool Count2/5

With 34 tools, this is a large surface for a server named Bookbrainz, yet only 3 tools (browse, lookup, search) actually serve that domain. The remaining 31 tools are unrelated Pipeworx/Polymarket functionality, making the tool count inappropriate for the stated server purpose and suggesting a mislabeled or overloaded server.

Completeness2/5

The BookBrainz domain is severely incomplete: it offers read-only access (search, browse, lookup) but no create, update, or delete operations for entities. For the broader Pipeworx/Polymarket functionality, coverage is quite deep, but that is not the server's stated domain. This leaves a fundamental gap for the BookBrainz use case.
