The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill communicates with the Crossref REST API (api.crossref.org) to retrieve scholarly metadata. Crossref is a well-known, established service for the scientific community, and these requests are necessary for the skill's primary function of citation discovery.
[COMMAND_EXECUTION]: The workflow relies on executing a local Python script (nature_citation.py) to segment text, perform network searches, and write reference files. The script uses only standard Python libraries and operates within the parameters provided by the user.
[INDIRECT_PROMPT_INJECTION]: The skill ingests untrusted external data in the form of article titles and abstracts from the Crossref API, which creates a potential surface for indirect prompt injection.
Ingestion points: External metadata is fetched in scripts/nature_citation.py via the fetch_crossref and fetch_crossref_doi functions.
Boundary markers: The results are structured into segment-based reports and a citation browser, separating source text from search results.
Capability inventory: The script has the capability to perform network GET requests and write various citation formats (JSON, TSV, HTML, ENW, RIS, RDF) to the local disk.
Sanitization: The script proactively sanitizes external content using html.escape, xml.sax.saxutils.escape, and json.dumps before generating any review artifacts, significantly mitigating the risk of malicious payloads affecting the agent or the user's browser.
