I'm a bit confused by your question. I'll make some comments, but let me know if I have not answered what you want.
1) Created in the last 10 days.
DBMS_JOB : I don't think there is a record of the job creation time anywhere.
DBMS_SCHEDULER : Try the DBA_SCHEDULER_JOB.START_DATE.
2) Script of tasks:
DBMS_JOB : Look at the DBA_JOBS.WHAT column to see what the job does.
DBMS_JOB : Look at the DBA_SCHEDULER_JOBS.JOB_ACTION column to see what the job does.
3) Result of tasks:
DBMS_JOB : The FAILURES and BROKEN columns in DBA_JOBS give you some indication problems. Sometimes, job failures are sometimes written in the alert log and trace files, depending on the cause.
DBMS_SCHEDULER : The STATUS and ERROR# columns of the DBA_SCHEDULER_JOB_RUN_DETAILS view tell you the result of the each run. Once again, job failures are sometimes written in the alert log and trace files, depending on the cause.
