Chronicler searches local history sources (Chrome browser history, terminal/shell history) to answer questions about past activity. Sources are pluggable — register only the ones available on each machine.
Chronicler is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/chronicler/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when you need to find what happened, when it happened, or retrace activity.
The Chronicler Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
