The Agent Skills Directory

[COMMAND_EXECUTION]: The skill instructs the agent to use curl for interacting with the Wayback Machine CDX and Availability APIs. It also performs local network requests to the Chromium remote-debugging port (default 9222) to verify connectivity.
[EXTERNAL_DOWNLOADS]: The skill fetches capture metadata and archival content from the Internet Archive's Wayback Machine (archive.org and web.archive.org), which are well-known services. These downloads are restricted to data retrieval and research purposes.
[DATA_EXFILTRATION]: Network activity is limited to authorized Wayback Machine API queries and local Chromium debugging. The skill explicitly forbids bypassing network-header redaction or seeking credentials through process introspection.
[PROMPT_INJECTION]: While the skill ingests external content from websites and APIs, it provides clear boundaries to mitigate indirect prompt injection risks.
Ingestion points: Browser snapshots, screenshots, and JSON responses from Wayback Machine APIs.
Boundary markers: Mandatory use of specific pageId handles for every scoped tool and instructions to avoid surfacing unrelated browser state.
Capability inventory: Includes browser navigation, JavaScript evaluation (evaluate_script), and snapshot generation.
Sanitization: The skill relies on structured snapshots and manual verification rather than raw data execution, and it restricts file output to authorized paths.
