Validate Claim

validate_claim
Read-onlyIdempotent

"Is it true that…" / "fact check" / "verify the claim that…" / "did X really…" / "was Y actually…" / "confirm or refute" / "true or false" — natural-language claim verification against authoritative sources. Use whenever the agent needs to check whether something a user said is factually correct. Company-financial claims (revenue, net income, cash for public US companies) verify via the structured SEC EDGAR + XBRL fast path with exact percent-delta math; ANY OTHER factual claim (macro statistics, rates, prices, drug data, records) automatically falls through to the grounded pipeline — routed to the right live source, answered with verbatim evidence, then judged. Returns a verdict (confirmed / approximately_correct / refuted / inconclusive / unsupported / could_not_verify), the grounded or structured actual value with pipeworx:// citation, and reasoning. IMPORTANT for callers: could_not_verify means the check did not happen (our LLM or source failed) and carries verification_error{stage,detail} — it is NOT evidence for or against the claim, and must not be shown as one. unsupported means we looked and cover no source for it. Replaces 4–6 sequential calls (NL parsing → entity resolution → data lookup → comparison).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
claimYesNatural-language factual claim, e.g., "Apple's FY2024 revenue was $400 billion" or "Microsoft made about $100B in profit last year".
tolerance_pctNoMax percent deviation still graded approximately_correct (0.5–50). Overrides the tolerance implied by the claim wording — set 1–2 for hallucination detection where any material error must be refuted. Default: implied by wording, capped at 5.

A4.9/5.0
Behavior5/5

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

Annotations declare read-only/idempotent/open-world, but description adds rich behavioral context: return verdict enum, grounded vs. structured pipeline, exact percent-delta math, verbatim evidence, and the distinction between could_not_verify and unsupported. It also exposes failure modes and caller responsibilities, going well beyond annotations.

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?

Description is long but every sentence earns its place: trigger phrases, routing rules, return values, and caller caveats. Front-loaded with natural-language examples, then core purpose, then details. Well-structured and not redundant.

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?

With no output schema, description carries the burden of explaining return values and verdicts, which it does thoroughly. It covers business logic, failure modes, and edge cases (could_not_verify vs unsupported) for a complete operational picture.

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 already describes both parameters with 100% coverage, so baseline is 3. Description additionally explains tolerance_pct's role in hallucination detection and how to set it (1–2 for strict material-error threshold), adding practical semantic value beyond the 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?

Description clearly identifies the tool as claim verification with specific verb 'verify' and resource 'claim', includes trigger phrases, and distinguishes from sibling tools by noting it replaces multi-step pipelines. It also differentiates sub-paths for financial vs. other claims, making the purpose unambiguous.

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

Usage Guidelines5/5

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

Explicitly states 'Use whenever the agent needs to check whether something a user said is factually correct' and describes the automatic routing logic. Provides guidance on tolerance_pct for hallucination detection and clarifies when not to interpret results (could_not_verify means check did not happen). This is strong usage guidance.

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

Many tools serve similar querying purposes (e.g., ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research) which could confuse an agent. However, detailed descriptions clarify differences, and some tools are very distinct (e.g., CIDR parsing, entity profile). Overlap is moderate but not severe.

Naming Consistency5/5

Tool names follow a consistent verb_noun pattern (e.g., resolve_entity, validate_claim, list_subscriptions) with underscores separating words. No mixing of styles like camelCase or abbreviations. Naming is clear and predictable.

Tool Count2/5

33 tools is excessive for a single server, covering areas as diverse as IP parsing, AI visibility, Polymarket betting, and SEC filings. This broad scope suggests the server tries to do too much, leading to a heavy and potentially unwieldy tool set.

Completeness3/5

The tool surface covers many domains (financials, prediction markets, IP tools, memory, subscriptions) but has notable gaps: no update for stored memories, limited subscription management (no modification), and some tools are marked as beta or deprecated. The set feels broad but not deep.
