model-review

A new model has shipped and the owner wants the setup checked against it. The checklist below is fixed; your judgment goes into what each hit means, not into which files to look at.

$0 is the new model id. $1, if given, is the model it replaces. If $0 is empty, ask for it — do not guess from the session model.

Step 0 — the standing decisions are not re-opened

Read the Sub-agents section of ~/.claude/CLAUDE.md: the tier lattice, which tier does what, and that effort lives per model in settings.json modelSettings. Apply it; do not copy it into your report and do not propose changing it. A new release changes which model an alias resolves to, not the lattice.

Step 1 — derive the targets. Never hand-list them

Run this block exactly, as one single Bash call: shell state does not survive between calls, so a grep split into its own call runs with no targets. It works under zsh and bash. The target set is whatever it prints today:

targets=("$HOME/.claude/scripts")
while IFS= read -r f; do targets+=("$f"); done \
  < <(find "$HOME/Library/LaunchAgents" -maxdepth 1 -name 'com.example.*.plist')
for d in "$HOME"/Dev/*/; do
  case "$(basename "$d")" in my-encyclopedia-app|my-bible-app|my-facilitation-app) continue ;; esac
  for s in scripts src options docs/triggers .claude/agents; do
    [ -e "$d$s" ] && targets+=("$d$s")
  done
done
ex=(--exclude-dir=node_modules --exclude-dir=.venv --exclude-dir=.git
    --exclude-dir=.next --exclude-dir=dist)

printf '%s\n' '--- 1. model pins'
grep -rnE 'claude-(opus|sonnet|haiku|fable)-[0-9]|--model|^model: *(opus|sonnet|haiku|fable)' \
  "${ex[@]}" "${targets[@]}"

printf '%s\n' '--- 2. failing control'
real=$(grep -rhE 'claude-(opus|sonnet|haiku|fable)-[0-9]' "${ex[@]}" "${targets[@]}" | wc -l)
typo=$(grep -rhE 'claude-(opsu|sonet|haiky|fabel)-[0-9]' "${ex[@]}" "${targets[@]}" | wc -l)
if [ "$real" -gt 0 ] && [ "$typo" -eq 0 ]; then
  printf 'control ok: real=%d misspelled=%d\n' $real $typo
else
  printf 'CONTROL FAILED: real=%d misspelled=%d — the probe proves nothing\n' $real $typo
