Canonical definition
Did you forget what you wanted to say but instantly remember once you walk back into the same room? That’s Context Effect – the tendency for memory to work better in the same environment where the information was learned.

Free cognitive-bias Agent Skill
Use Context Effect as a focused cognitive-bias lens. Explain the pattern, check whether it plausibly fits the situation, surface an alternative non-bias explanation, and return a practical counter-check without diagnosing people or claiming causation.
