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.

A4.6/5.0
Behavior5/5

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

Beyond the readOnly/openWorld/idempotent annotations, the description discloses the two execution paths (SEC EDGAR fast path vs. grounded pipeline), the exact verdict vocabulary, and crucial caveats about could_not_verify vs unsupported, which prevents the agent from misinterpreting failure as evidence.

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 long but efficiently front-loaded with trigger phrases and organized into purpose, routing, return value, and caveats. Every sentence provides distinct information, though it could be slightly condensed without loss.

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?

Given the tool's complexity and lack of an output schema, the description fully specifies the return value (verdict list, actual value, citation, reasoning) and edge cases, making it complete for the agent to use.

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

Parameters3/5

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

Schema coverage is 100% for both parameters, and the description does not add significant new parameter semantics beyond what the schema already provides (e.g., tolerance_pct is fully documented in the schema). Baseline of 3 is appropriate.

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 clearly identifies the tool as natural-language claim verification against authoritative sources, with trigger phrases and a specific use case ('fact check', 'verify the claim'). It distinguishes itself from generic Q&A tools by focusing on verifying factual claims and outlining two concrete pipelines.

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 differentiates company-financial claims from other factual claims, including how the system routes them. It also explains the outcome semantics, helping the agent decide when to trust results.

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

A3.5/5.0
Disambiguation2/5

Multiple tools serve overlapping functions: three ask_pipeworx variants, two deep research tools, and multiple polymarket tools. StockTwits-specific tools are distinct but the overall set has significant ambiguity between Pipeworx and Polymarket tools.

Naming Consistency2/5

Naming styles are mixed: some use lowercase (ask_pipeworx), some use underscores (ai_visibility_check), and some use prefixes (pipeworx_feedback, polymarket_arbitrage). No consistent pattern across the tool set.

Tool Count3/5

40 tools is on the higher end but not extreme. However, many tools belong to the Pipeworx ecosystem, which seems separate from StockTwits, making the set feel bloated and unfocused for a single server.

Completeness2/5

StockTwits social features are adequately covered (symbol search, streams, trending), but the inclusion of Pipeworx tools creates a sprawling surface without complete coverage in any one domain. Missing core StockTwits features like user profiles or direct messaging.
