 ### Fixes
 
+- Plugins/CLI: cache plugin CLI registration entries per command program so completion state generation does not repeat the full plugin sweep in one invocation. Thanks @ScientificProgrammer.
 - Plugins: reuse gateway-bindable plugin loader cache entries for later default-mode loads without serving default-built registries to gateway-bound requests, reducing repeated plugin registration during dispatch. Refs #61756. Thanks @DmitryPogodaev.
 - Gateway/secrets: include the caught error message in `secrets.reload` and `secrets.resolve` warning logs while keeping RPC errors generic, so operators can diagnose reload and permission failures. Thanks @davidangularme.
 - Anthropic-compatible streams: recover text deltas that arrive before their matching content block, so Kimi Code and similar providers do not finish as empty `incomplete_result` replies. Fixes #76007. Thanks @vliuyt.
