## Quality 89/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,952 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 3 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 7, about 1,952 tokens to load them all
- tool set hash: 040ba4f850ab023f12f7655ae23d6eca

- badge: [![protogrid quality](https://protogrid.dev/badge/app.ironledger/strength-calculators.svg)](https://protogrid.dev/servers/app.ironledger/strength-calculators)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-17 `check_program_file` added
  - 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.

- `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.
- `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.
- `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.
- `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.
- `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.
- `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.
