Deep Research

deep_research
Read-onlyIdempotent

ACCOUNT REQUIRED (free — sign in via GitHub at https://pipeworx.io/signup; depth:"thorough" needs a paid plan). If you are not signed in, use ask_pipeworx instead — it works on every tier. Grounded multi-source research across Pipeworx's 1866 STRUCTURED data sources (SEC filings, FRED/BLS economics, FDA, USPTO patents, markets, science, government records, etc.) in ONE call — this is NOT open-web search. Decomposes your question into focused facets, routes each to the right one of 7,188 tools IN PARALLEL, and returns a findings packet: verbatim evidence + confidence + source + fetched_at + a stable pipeworx:// citation per finding, with explicit gaps[] for facets the data couldn't answer (never invented). Best for broad/multi-part questions over structured data ("compare X and Y's regulatory + financial exposure", "research the filings + market picture for ACME"). For a single lookup use ask_pipeworx (one LLM call, not many). For BREAKING or colloquial CURRENT-NEWS / "what's the world saying about X" topics, prefer ask_pipeworx — it routes to live news APIs and the *-news-feeds packs; deep_research returns mostly empty gaps[] when the topic isn't in the structured catalog. Second-hop iteration: depth:"standard" re-angles unanswered gaps (gap recovery); depth:"thorough" additionally chases the best leads from the first pass — so multi-step questions resolve in one call. Every finding carries a hop field and a citation_uri — a resolvable pipeworx:// record URI, present only when the source emits one that resources/read can actually serve, so a citation you get back is always fetchable. "standard" and "thorough" also return contradictions[] flagging findings that disagree. Large records are semantically excerpted to the passages relevant to each facet (not head-truncated), so answers deep in a long filing/series aren't missed. Expect 15-60s (thorough with its follow-up + contradiction pass: up to ~90s).

TDQS

A4.9/5.0
Behavior5/5

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

Annotations only cover readOnly/idempotent/openWorld, and the description adds substantial behavior: account requirement and plan tier, expected latency (15-60s, up to ~90s for thorough), empty gaps[] on out-of-catalog topics, contradictions[] only on standard/thorough, a per-finding hop field, semantic (not head-) excerpting of long records, and the guarantee that returned citation_uri values are actually resolvable via resources/read. It is consistent with the read-only 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?

Front-loaded with the gating fact (account required, fallback tool) before anything else, which is the right order for an agent. It is a dense block, though: the ask_pipeworx comparison appears three times and the citation_uri resolvability point is spelled out at length, so some trimming is possible without losing information.

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?

There is no output schema, yet the description accurately describes the return shape (verbatim evidence, confidence, source, fetched_at, pipeworx:// citation, hop, gaps[], contradictions[]), and the 9-parameter surface is dominated by string aliases the schema already enumerates. Nothing an agent needs to decide or call correctly is missing.

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

Parameters5/5

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

Schema coverage is 100% and the depth enum is already documented, so the baseline is 3; the description still adds meaning by explaining the second-hop semantics ('standard re-angles unanswered gaps; thorough additionally chases the best leads') and that thorough requires a paid plan. That connects the parameter value to observable output differences rather than just repeating the enum.

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?

States a concrete verb and resource: 'Grounded multi-source research across Pipeworx's 1866 STRUCTURED data sources ... in ONE call', and explicitly negates the adjacent category with 'this is NOT open-web search'. It also distinguishes itself mechanistically (decomposes into facets, routes to 7,188 tools in parallel, returns evidence + confidence + citation + gaps[]), which is far beyond restating the name.

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?

Gives both when-to-use ('broad/multi-part questions over structured data', with two concrete example questions) and when-not: single lookups -> ask_pipeworx, breaking/colloquial news -> ask_pipeworx because deep_research returns empty gaps[] outside the structured catalog. It also states the auth fallback (ask_pipeworx works on every tier) and the paid-plan gate on depth:'thorough'.

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