Add ClinicalTrials.gov CLI

Goal

Add a Printing Press CLI for ClinicalTrials.gov, focused on trials search, sponsor intelligence, condition pipelines, and change monitoring.

Free source

• ClinicalTrials.gov public API.

Agent jobs

• Find recruiting trials for a condition/intervention.
• Research a sponsor/company pipeline.
• Track new or changed trials in a therapeutic area.
• Summarize phase/status/location patterns for a market or research brief.

Proposed command shape

• clinicaltrials-pp-cli search --condition melanoma --recruiting --agent
• clinicaltrials-pp-cli sponsor "Eli Lilly" --agent
• clinicaltrials-pp-cli trial NCT00000000 --agent
• clinicaltrials-pp-cli changed --condition obesity --since 30d --agent
• clinicaltrials-pp-cli pipeline --sponsor "Moderna" --agent

Non-goals

No medical advice, enrollment actions, patient matching beyond public filters, or claims of clinical efficacy.\n\n## Implementation path\n\nThis is a new CLI candidate, so do not hand-build it directly in this published library repo. Run it through the canonical Printing Press generation flow in cli-printing-press, keep manuscripts/proofs, then publish into this repo with the publish flow.\n\n## Acceptance criteria\n\n- Research notes explain the source/API/feed contract, rate limits, auth needs, and freshness behavior.\n- CLI exposes a small agent-native command set, not a raw endpoint dump.\n- --json / --agent output is stable and compact.\n- If the source benefits from history, add local SQLite sync plus since/diff commands.\n- Skill includes high-signal recipes and clear non-goals.\n- Dogfood proves at least three realistic agent workflows.
