slm-status

# slm-status — Health and Optimize Stats ## Purpose Use this skill to answer: "Is SLM healthy?", "Is compression/caching actually saving tokens?", and "What does the system look like right now?" It covers three surfaces: the MCP stats tool, the `slm status` CLI, and the `slm doctor` preflight. ## Primary MCP Tool: slm_optimize_stats ``` slm_optimize_stats() -> dict ``` No arguments. Returns counters from the current daemon and MCP process session. ### Return dict (all keys always present) | Key | Type | Meaning | |-----|------|---------| | `ok` | bool | `True` on success; `False` on internal error | | `compress_runs` | int | Total compress calls recorded by the daemon (persisted across restarts) | | `tokens_saved_compress` | int | Cumulative tokens saved by compression (daemon-persisted) | | `cache_proxy_hits` | int | Proxy-layer cache hits (daemon-persisted) | | `cache_proxy_misses` | int | Proxy-layer cache misses (daemon-persisted) | | `cache_kv_hits` | int | MCP KV cache hits — **this MCP process session only**, resets on restart | | `cache_kv_misses` | int | MCP KV cache misses — **this MCP process session only**, resets on restart | | `ccr_note` | str \| None | Note about CCR entry count (not tracked per-session; see daemon `/api/v1/metrics`) | | `note` | str \| None | Scope clarification or error detail | ### Important scope distinction `compress_runs`, `tokens_saved_compress`, `cache_proxy_hits`, and `cache_proxy_misses` are **daemon-persisted** — they surviv...
