lastXdays Skill

Summarize what happened in the last N days (or a specific YYYY-MM-DD → YYYY-MM-DD range) about a user-provided topic.

Default behavior is web-first (web_search + selective web_fetch). If optional credentials/data are available, you may ingest Reddit via API and X via x-cli (preferred), API, or local archive, falling back to web search if unavailable.

Trigger Patterns

Activate when the user message contains any of:

• lastXdays / lastxdays
• last x days
• A question like: "what happened in the last N days" (optionally followed by a topic)

Default Model

Default to sonnet (anthropic/claude-sonnet-4-6) when spawning as a subagent.

Use flash (openrouter/google/gemini-2.0-flash-001) only for simple single-source lookups (one topic, one platform, straightforward synthesis with no file reading required). Flash is unreliable for multi-step agentic work requiring tool chaining (search → fetch → read files → synthesize → report). When in doubt, use sonnet.
