Audits a Claude Code or Codex setup for context-window waste, fixes it with the user's approval, and measures the saving. Use when context feels tight, sessions degrade, or costs climb.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Token Optimizer
Measures where a setup spends its context window, proposes fixes, applies the ones the user approves, and re-measures. The deliverable is a before-and-after the user can verify, with every change backed up. Typical recovery is 5-15% of the window from config cleanup, more when compaction and caching settings are wrong for the way the user works.
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.
## Step 0: pick the right workflow for this runtime
The audit below reads and edits `~/.claude`, which is the wrong target anywhere but Claude Code, so settle the runtime before touching any path. Run exactly this, in this order.
**a. Environment check** (touches no file; an explicit `TOKEN_OPTIMIZER_RUNTIME` wins, and Claude plugin variables are checked before stray `OPENCODE_*` exports, the same order `detect_runtime()` uses):
```bash
if [ "${TOKEN_OPTIMIZER_RUNTIME:-}" = "claude" ] || [ "${TOKEN_OPTIMIZER_RUNTIME:-}" = "codex" ]; then

How to install
mdr add alexgreensh/token-optimizer/token-optimizer@sha256:0afe28cf1d20f51fThe line at the top of this page pins the label git:20261010.f756a67, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
