Content-addressed cache for AI agent loops. Returns exact bytes from prior executions instead of re-running tools or re-calling LLMs.

Think of it like make: make doesn’t recompile foo.o if foo.c hasn’t changed, because the inputs haven’t changed so the output can’t have changed. Verdant applies the same idea to agent tool calls and LLM completions.

A normal cache keys on the string "cargo test" and guesses with a TTL. Verdant keys on actual content:

key = blake3(
    command  + cwd
  + hash(src/lib.rs) + hash(src/main.rs) + hash(Cargo.lock) + ...
  + env(RUSTFLAGS, CARGO_TARGET_DIR)
)

A hit is a proof (inputs identical), not a gamble (time-based expiry).

Numbers

23.3% tool-time savings on real agent runs
99.97% LLM latency saved on cache hits
Zero divergences under verify mode (dual-runs every hit, byte-compares)
