Get ORCID Work Details (Bulk)

orcid_get_work_detail

Read-onlyIdempotent

Fetch full detail records for 1–100 works by their put-codes in a single request. Put-codes are returned by orcid_get_works in the putCode field of each work entry. Returns the abstract (short-description), contributors with CRediT roles, the external IDs on that record (DOI, PMID, arXiv, ISBN, etc.), citation metadata (BibTeX or other formats when provided), journal title, URL, and the source that added it for each work. A record listing more than 100 contributors keeps the first 100 plus the requested researcher's own entries, with contributorCount giving the total and contributorsTruncated set; a citation over 8,192 bytes is left out and flagged by citationOmitted. Per-record errors (not-found or inaccessible put-codes) are surfaced as error entries rather than failing the whole call. Records are added while the response stays within its 64,000-byte budget; put-codes left out are returned in deferredPutCodes to pass back in a follow-up call. A repeated put-code is fetched once.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`orcid_id`	Yes	ORCID iD — bare (0000-0001-2345-6789) or as an orcid.org URI (https://orcid.org/0000-0001-2345-6789). The check digit may be X or x.
`put_codes`	Yes	Array of 1–100 work put-codes to fetch. Put-codes are available in the putCode field returned by orcid_get_works. A repeated put-code is fetched once. Any the 64,000-byte response budget leaves out come back in deferredPutCodes.

Output Schema

TableJSON Schema

Name	Required	Description
`error`	No	Present when the call failed. Absent on success.
`works`	No	Successfully resolved work detail records.
`errors`	No	Per-record errors for put-codes that could not be resolved (not found or inaccessible). Empty when all put-codes resolved successfully.
`notice`	No	Note when the response budget deferred some put-codes — call again with deferredPutCodes.
`orcidId`	No	Normalized ORCID iD (bare format).
`orcidUri`	No	Full ORCID URI.
`deferredPutCodes`	No	Requested put-codes left out because adding them would exceed the 64,000-byte response budget. Pass them as put_codes in another call to fetch them. Omitted when every put-code was fetched.

A4.6/5.0

Behavior5/5

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

Annotations already declare readOnly/idempotent/openWorld, yet the description adds substantial non-obvious behavior: 100-contributor truncation with contributorCount and contributorsTruncated flags, the 8,192-byte citation cap flagged by citationOmitted, per-record errors surfaced instead of failing the batch, the 64,000-byte response budget with deferredPutCodes, and put-code deduplication.

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 core action and input source, then layers edge-case behavior in discrete clauses. It is dense and long, but nearly every sentence conveys a distinct, actionable constraint rather than filler.

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 an output schema present the description needn't document return fields, yet it still covers truncation, omission, error, and budget behavior that the output schema alone would not make obvious. Combined with annotations covering the safety profile, an agent has everything needed to call and interpret this tool.

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%, so the baseline is 3, but the description adds real meaning: put_codes must come from orcid_get_works' putCode field, repeats are fetched once, and omitted codes return via deferredPutCodes. It also reinforces the 1–100 bound that the schema enforces.

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 specific verb (fetch), resource (full detail records for works), scope (1–100 by put-codes in a single request), and contrasts implicitly with the sibling orcid_get_works that produces the put-codes. An agent can distinguish it from orcid_get_works without opening either schema.

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?

Explicitly names the source of its required input (putCode field from orcid_get_works) and explains the follow-up workflow for deferredPutCodes, which is real routing guidance. It lacks an explicit when-not-to-use statement or a named alternative for retrieving a single work, so it falls short of a 5.

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