## Description

Coaches a token-efficient Claude Code or Codex setup from the user's own usage data. Use when planning a build, fixing a slow or costly setup, or deciding which workflow steps need a model.

# Token Coach

A coaching conversation about where the user's tokens go and what to change, grounded in numbers measured on their machine. The deliverable is a short, prioritised action plan the user agrees with. For a full audit that edits their setup, hand over to `token-optimizer`.

Token Optimizer's own skills (`token-optimizer`, `token-coach`, `token-dashboard`, `fleet-auditor`, `resume-checkpoint`) are the measurement layer, so leave them out of every unused-skill, archive or consolidation suggestion, however rarely they run.

## 1. Collect the data

Run exactly this first. It finds the newest installed copy, so a stale plugin cache never answers:

```bash
RUNTIME="${TOKEN_OPTIMIZER_RUNTIME:-}"
if [ -z "$RUNTIME" ]; then
  if [ -n "$CLAUDE_PLUGIN_ROOT" ] || [ -n "$CLAUDE_PLUGIN_DATA" ]; then
    RUNTIME="claude"
  elif [ -n "$OPENCODE" ] || [ -n "$OPENCODE_BIN" ] || [ -n "$OPENCODE_CONFIG_DIR" ] || [ -n "$OPENCODE_CONFIG" ]; then
    RUNTIME="opencode"
  elif [ -n "$CODEX_HOME" ]; then
    RUNTIME="codex"
  # Explicit config-dir env of another harness: same tier as Python's
  # detect_runtime() (above CLAUDECODE, which every Claude Code child inherits).
  elif [ -n "$HERMES_HOME" ]; then
    RUNTIME="hermes"
  elif [ -n "$COPILOT_HOME" ] || [ -n "$TOKEN_OPTIMIZER_COPILOT_HOME" ]; then
    RUNTIME="copilot"
  elif [ -n "$TOKEN_OPTIMIZER_CURSOR_HOME" ]; then
    RUNTIME="cursor"
  elif [ -n "$TOKEN_OPTIMIZER_ANTIGRAVITY_HOME" ]; then
    RUNTIME="antigravity"
  elif [ -n "$GROK_HOME" ] || [ -n "$TOKEN_OPTIMIZER_GROK_HOME" ]; then
    RUNTIME="grok"
  elif [ -n "$CLAUDECODE" ] || [ -n "$CLAUDE_CODE_ENTRYPOINT" ] || [ -n "$CLAUDE_CODE_SESSION_ID" ]; then
    RUNTIME="claude"
  elif [ -d "$HOME/.config/opencode" ] && [ ! -d "$HOME/.codex" ]; then
    RUNTIME="opencode"
  elif [ -d "$HOME/.codex" ]; then
    RUNTIME="codex"
  else
    RUNTIME="claude"
  fi
fi
