Ingest-and-integrate an artifact someone points at with a terse, deliberately under-articulated directive — "check this out", "lets research this", "look into this", "wdyt" — followed by a URL, repo, paper, file, image, or pasted document. Infers the actual request from a fully-contextualized frame (who is asking + what they're working on + what's already known) WITHOUT bouncing a clarifying question back, then runs the pipeline: contextualize → deep research (verify every source) → analyze → connect → document the finding → suggest ranked next steps. The artifact ends up metabolized into knowledge and action, not left as a one-paragraph summary. Composes existing research/search/memory tools; it does not reimplement them. USE WHEN: check this out, checkit, /checkit, lets research this, research this, look into this, dig into this, wdyt, what do you think of this, found this, take a look + an artifact; or whenever an artifact is shared with an underspecified ask. NOT FOR: retrospective "what have I been doing repeatedly" (a discovery/look-back task); fully-specified artifact asks ("summarize this PDF in 3 bullets", "fix the bug in this file" — answer directly). Triggers on those phrases + a shared artifact.

From the source SKILL.md

Someone drops a URL / repo / paper / file / image with a terse directive — "check this out", "lets research this", "wdyt". The intent is real but unstated by design: they're delegating the articulation, not just the work.

What this skill does

Checkit 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/checkit/ and loads when your prompt matches the skill's trigger.

When to invoke it: USE WHEN: check this out, checkit, /checkit, lets research this, research this, look into this, dig into this, wdyt, what do you think of this, found this, take a look + an artifact; or whenever an artifact is shared with an underspecified ask. NOT FOR: retrospective "what have I been doing repeatedly" (a discovery/look-back task); fully-specified artifact asks ("summarize this PDF in 3 bullets", "fix the bug in this file" — answer directly).

Who uses this skill
