Generate a focused report from the current conversation and persist insights. Use when a user has been exploring papers, asking questions, and wants to capture what was discussed. Triggers -- "make a report from this", "save what we discussed", "write up what we covered", "turn this into a document".

Generate integrated cross-paper explanations from KB cards. Use when a user asks to explain, compare, synthesize, understand, or deep-dive into one or more knowledge base cards, or asks how cards relate or work together.

Search Hacker News for practitioner discussions on a topic, tool, library, or paper, and synthesize findings into structured KB cards. Use when a user asks about community sentiment, real-world experience, practitioner opinions, or HN discussions about a technology, project, or research paper.

INTERNAL SUBAGENT SKILL — never invoke directly. This is called automatically by $hn-synthesis when it spawns a thread-analysis subagent. If a user asks about HN discussions, use $hn-synthesis instead.

Create, manage, and monitor scheduled jobs. Use when a user wants to run something on a schedule (e.g., 'run this every 2 hours', 'set up a daily digest', 'create a cron job for...'), check job status, view run history, or manage the scheduler daemon. This skill covers the full job lifecycle: creation, scheduling, monitoring, and cleanup.

The knowledge base is a directory of markdown files with YAML frontmatter. All operations use standard file tools (read, write, ls, grep).

Generate a concise research briefing from KB cards or a topic. Use when a user wants a quick overview, orientation, summary of approaches, or wants to understand what their options are before diving deep. Use instead of cross-paper-report when the user wants brevity over depth. Examples -- "give me a quick overview of VLA approaches", "what are my options for sim-to-real", "summarize what I have on diffusion policies", "brief me on action tokenization methods".
