Operate ClinicalTrials.gov through your OOMOL-connected account. This skill calls the clinicaltrials_gov connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.
Running an action
ClinicalTrials.gov needs no account connection. Assume the oo CLI is installed and signed in. Do not run oo auth login proactively — just run the action. Fall back to First-time setup only when a command actually fails.
1. Inspect the contract to get the authoritative input/output schema before building a payload:
oo connector schema "clinicaltrials_gov" --action "<action_name>"
2. Run the action with a JSON payload that matches the input schema:
oo connector run "clinicaltrials_gov" --action "<action_name>" --data '<json>' --json
--data takes a JSON object string or @path/to/file.json; omit it to send {}.- The response is
{ "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.
Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action’s live schema with oo connector schema to get its authoritative input fields.
Available actions
get_api_version — Get the current ClinicalTrials.gov API version and daily data refresh timestamp.get_field_value_statistics — Get value statistics for selected ClinicalTrials.gov leaf fields or field data types.get_list_field_size_statistics — Get observed list-size statistics for selected ClinicalTrials.gov array fields.get_registry_size_statistics — Get ClinicalTrials.gov registry counts and the distribution of study JSON record sizes.get_studies_by_nct_ids — Get multiple ClinicalTrials.gov studies by NCT identifier and report identifiers that were not found.get_study — Get one ClinicalTrials.gov study by NCT identifier.get_study_documents — List uploaded study protocols, statistical analysis plans, and informed consent forms with their official metadata.get_study_eligibility — Get patient-facing eligibility criteria, age and sex requirements, and study population details for one ClinicalTrials.gov study.get_study_locations — Get study sites, geographic coordinates, central contacts, local contacts, and study officials for one ClinicalTrials.gov study.get_study_metadata — Get the official ClinicalTrials.gov study data model and field definitions.get_study_results — Get posted participant flow, baseline characteristics, outcome measures, adverse events, and result notes for one ClinicalTrials.gov study.list_enums — List official ClinicalTrials.gov enumeration types, values, legacy values, and field usages.list_search_areas — List the official ClinicalTrials.gov search documents, areas, parameters, and indexed pieces.search_studies — Search ClinicalTrials.gov studies with official Essie queries, filters, field selection, sorting, and cursor pagination.
Safety
- Untagged actions are reads (get / list / search) — safe to run directly.
- Actions tagged
[write] change ClinicalTrials.gov state — confirm the exact payload and effect with the user before running.
- Actions tagged
[destructive] remove or overwrite data — always confirm the target and get explicit approval first.
First-time setup
These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.
-

# ClinicalTrials.gov
Operate **ClinicalTrials.gov** through your OOMOL-connected account. This skill calls the `clinicaltrials_gov` connector with the [oo CLI](https://github.com/oomol-lab/oo-cli); OOMOL injects credentials server-side, so you never handle raw tokens.
## Running an action
ClinicalTrials.gov needs no account connection. Assume the oo CLI is installed and signed in. **Do not run `oo auth login` proactively — just run the action.** Fall back to [First-time setup](#first-time-setup) only when a command actually fails.
**1. Inspect the contract** to get the authoritative input/output schema before building a payload:
```bash
oo connector schema "clinicaltrials_gov" --action "<action_name>"
```
**2. Run the action** with a JSON payload that matches the input schema:
```bash
oo connector run "clinicaltrials_gov" --action "<action_name>" --data '<json>' --json
```
- `--data` takes a JSON object string or `@path/to/file.json`; omit it to send `{}`.
- The response is `{ "data": ..., "meta": { "executionId": "..." } }`; the execution id lives under `meta.executionId`.
Each action is listed below with a one-line description; actions that change state carry a `[write]` or `[destructive]` tag. Before constructing `--data`, fetch the action's live schema with `oo connector schema` to get its authoritative input fields.
## Available actions
- `get_api_version` — Get the current ClinicalTrials.gov API version and daily data refresh timestamp.
- `get_field_value_statistics` — Get value statistics for selected ClinicalTrials.gov leaf fields or field data types.
- `get_list_field_size_statistics` — Get observed list-size statistics for selected ClinicalTrials.gov array fields.
- `get_registry_size_statistics` — Get ClinicalTrials.gov registry counts and the distribution of study JSON record sizes.
- `get_studies_by_nct_ids` — Get multiple ClinicalTrials.gov studies by NCT identifier and report identifiers that were not found.
- `get_study` — Get one ClinicalTrials.gov study by NCT identifier.
- `get_study_documents` — List uploaded study protocols, statistical analysis plans, and informed consent forms with their official metadata.
- `get_study_eligibility` — Get patient-facing eligibility criteria, age and sex requirements, and study population details for one ClinicalTrials.gov study.
- `get_study_locations` — Get study sites, geographic coordinates, central contacts, local contacts, and study officials for one ClinicalTrials.gov study.
- `get_study_metadata` — Get the official ClinicalTrials.gov study data model and field definitions.
- `get_study_results` — Get posted participant flow, baseline characteristics, outcome measures, adverse events, and result notes for one ClinicalTrials.gov study.
- `list_enums` — List official ClinicalTrials.gov enumeration types, values, legacy values, and field usages.
- `list_search_areas` — List the official ClinicalTrials.gov search documents, areas, parameters, and indexed pieces.
- `search_studies` — Search ClinicalTrials.gov studies with official Essie queries, filters, field selection, sorting, and cursor pagination.
