Skill: scientific threshold and context inference

Use this skill when the user wants SQL data where the agent must infer hidden expert rules rather than just read column names. Trigger it for requests like “make the model use an unstated threshold”, “the question should rely on domain conventions”, “approved should not just mean a boolean flag”, or “it should need scientific background to write the SQL correctly.” Example trigger: “The hard part should be an implied threshold.” Example trigger: “I want expert-rule SQL, not literal schema matching.” Example trigger: “The model should have to infer what counts as significant or approved.”

Skill: temporal tabular reasoning

Use this skill when the user wants SQL tasks where time is the main source of difficulty. Trigger it for requests like “make it about first vs last”, “use date windows or age at event time”, “test recency and ordering”, or “the answer should change if the timeline is read incorrectly.” Example trigger: “I want first/last/most recent style SQL questions.” Example trigger: “Make time order and date arithmetic central.” Example trigger: “The model should fail if it misreads the timeline.”
