 ## Overview
 
-The one-shot token library is an `LD_PRELOAD` shared library that provides **single-use access** to sensitive environment variables containing GitHub, OpenAI, Anthropic/Claude, and Codex API tokens. When a process reads a protected token via `getenv()`, the library returns the value once and immediately unsets the environment variable, preventing subsequent reads.
+The one-shot token library is an `LD_PRELOAD` shared library that provides **cached access** to sensitive environment variables containing GitHub, OpenAI, Anthropic/Claude, and Codex API tokens. When a process reads a protected token via `getenv()`, the library caches the value in memory and immediately unsets the environment variable. Subsequent `getenv()` calls return the cached value, allowing the process to read tokens multiple times while `/proc/self/environ` is cleared.
 
-This protects against malicious code that might attempt to exfiltrate tokens after the legitimate application has already consumed them.
+This protects against exfiltration via `/proc/self/environ` inspection while allowing legitimate multi-read access patterns that programs like the Copilot CLI require.

 - **Static linking**: Programs statically linked with libc bypass LD_PRELOAD
