/volley:diagnose

One-shot diagnosis of whether Volley is wired up correctly here. Run each check, print a [PASS]/[FAIL]/[WARN] line, and end with a remediation list for anything not green.

Steps for Claude

1. Codex CLI present. Run codex --version. PASS if it prints a version >= 0.156; FAIL otherwise (remedy: npm install -g @openai/codex).
2. Codex runs non-interactively. Run codex exec --help; PASS if it succeeds, FAIL otherwise (remedy: update Codex with npm install -g @openai/codex). Then WARN if any .mcp.json in this repo still registers codex mcp-server (remedy: remove that entry - Codex 0.156 removed the command and Volley no longer uses MCP). Do not make a model call here.
3. Platform terminal available. Detect the OS and check for a usable terminal launcher:

   case "$(uname -s)" in
     Darwin*) command -v osascript >/dev/null && echo "[PASS] macOS terminal (osascript)" || echo "[FAIL] osascript missing" ;;
     Linux*)  { command -v gnome-terminal || command -v kitty || command -v tmux; } >/dev/null \
                && echo "[PASS] Linux terminal (gnome-terminal/kitty/tmux)" \
                || echo "[FAIL] no gnome-terminal/kitty/tmux - install one or use VOLLEY_PLATFORM=tmux" ;;
     MINGW*|MSYS*|CYGWIN*) command -v wt >/dev/null && echo "[PASS] Windows Terminal (wt)" || echo "[FAIL] wt missing - install Windows Terminal" ;;
     *) echo "[WARN] unrecognized OS; set VOLLEY_PLATFORM=tmux for the universal fallback" ;;
   esac

4. Plugin assets intact. Confirm the bundled scripts resolve:

   for f in scripts/lib.sh scripts/codex-exec.sh scripts/spawn-codex.sh scripts/platforms/windows.sh scripts/platforms/macos.sh scripts/platforms/linux.sh scripts/platforms/tmux.sh; do
     [ -f "${CLAUDE_PLUGIN_ROOT}/$f" ] && echo "[PASS] $f" || echo "[FAIL] missing $f"
   done

5. Per-repo lock state. If .volley/STATE exists, report it and whether the named process is alive; otherwise note the repo isn't initialized:

   if [ -f .volley/STATE ]; then
     active=$(grep -E '^ACTIVE=' .volley/STATE | cut -d= -f2)
     task=$(grep -E '^TASK=' .volley/STATE | cut -d= -f2)
     pid=$(grep -E '^PID=' .volley/STATE | cut -d= -f2)
     echo "[INFO] lock: ACTIVE=$active TASK=$task PID=$pid"
     if [ -n "$pid" ] && [ "$pid" != "0" ]; then
       kill -0 "$pid" 2>/dev/null && echo "[INFO] named PID $pid is alive" \
         || echo "[WARN] named PID $pid is dead - lock may be stale; run /volley:unlock if it's stuck"
     fi
   else
     echo "[WARN] .volley/ not initialized here - run /volley:setup"
   fi

6. Continuity + model config (v0.2). Non-mutating, and no model turn unless the user explicitly asks for a live model probe.
   • Config parses & validates. Read .volley/config.json (parse yourself - no jq). PASS if valid JSON with a known version; WARN if absent (= defaults in effect); FAIL if present but malformed or unknown version. Report the resolved review/implementation model + reasoningEffort (show inherit as "Codex default"). Do not call a model to check availability here - note that model validity is confirmed by the /volley:setup smoke call (or an opt-in --live probe).
   • Repository identity. Compare .volley/local.json repository to the live repo:

     . "${CLAUDE_PLUGIN_ROOT}/scripts/lib.sh"
     if [ -f .volley/local.json ]; then
       # extract stored root/remote in-host (JSON), then:
       volley_repo_identity_matches "<stored_root>" "<stored_remote>" \
         && echo "[PASS] repo identity matches live checkout" \
         || echo "[WARN] repo identity mismatch - stored session IDs will be ignored (fresh session + file rehydration)"
     else
       echo "[INFO] no .volley/local.json yet - run /volley:setup"
     fi

   • Context files. For each context.required file, PASS if present / FAIL if missing (names the file). For context.optional, list present vs skipped.
   • Saved-session integrity. If .volley/local.json has role thread/session IDs, report them as present (never print secrets); WARN if the file is unreadable/corrupt.
   • Managed checkpoint. PASS if .volley/CHECKPOINT.md exists and still contains both volley:managed markers; WARN otherwise.
7. Summary. Print a final Volley diagnose: N passed, M warnings, K failures line and, for each FAIL/WARN, the one-line remedy.
