  A server that changes its tool descriptions after being approved ("rug pull") can slip new instructions to agents. Re-check what changed before trusting it.

• one_rep_max

  Estimate a one-rep max (1RM) from a set of weight × reps, with a percentage table and the load each rep count should allow. Epley by default, Brzycki optional. Estimates above 10 reps are flagged as less reliable.

• rpe_estimate_max

  Estimate a one-rep max from weight, reps and RPE, treating RPE as reps in reserve (RPE 8 = 2 reps left) and applying the one-rep max formula to reps + reps in reserve.

• rpe_target_load

  Find the load for a set of a given number of reps at a target RPE, from a known or estimated one-rep max. Rounded to the nearest 0.5.

• plate_loading

  Work out which plates to put on each side of a barbell to reach a target weight, using standard gym plates or the plates you list. Reports the exact load and anything your plates can’t make.

• warmup_sets

  Build a warm-up ramp to a working weight: plate-friendly jumps, reps falling from 10 to singles, with the plates for each set. The same ramp the IronLedger app suggests.

• powerlifting_score

  Score a powerlifting total (or a bench press) against bodyweight with DOTS, IPF GL points and the original Wilks, using the coefficients the OpenPowerlifting rankings use.

• check_program_file

  Check a training program written as a CSV or TSV file exactly as the IronLedger app will import it, before anyone loads it on a phone. Returns the weeks, sessions and exercises it creates, every skipped row and warning with its row number, the exercise names the app will question ("Did you mean ...?"), and names that will become new custom exercises. Use it whenever you write a program for someone to import into IronLedger, and fix anything it reports first. The app names the program after the file, so pass the file name you will give it.
