Crate dejavu 

Dejavu — a local output-reduction proxy for coding agents.

Dejavu intercepts common shell commands via PATH shims, runs the real command, and returns a compact/diffed view to the agent while preserving the exact exit code. It reduces what the agent reads, never what the shell executes.

Modules

agent

dejavu start — launch a coding agent with output reduction active.

cli

CLI dispatch and the shared application context.

commands

Read-only / management CLI command handlers.

config

Effective configuration (spec §18): defaults ← global config.toml ← project .dejavu.toml. Each layer supplies only the keys it overrides.

env

DEJAVU_* environment variable names and the ambient session view.

error

Typed error enums for the library. Binaries convert these at the boundary with anyhow.

exec

Execution core: shim generation, PATH handling, anti-recursion real-binary resolution, process spawning, and classification/passthrough policy.

paths

Cache/config path resolution and the per-repo cache layout.

reduce

Output reduction. The reduce() facade normalizes, hashes, finds a comparable prior run, classifies, and builds the compact output the agent sees — without writing anything (the runtime persists logs + the record).

repo

Repo root detection and git-state metadata capture.

runtime

The dejavu run pipeline: resolve → classify → exec → reduce → emit, with the absolute exit-code guard.

state

Per-repo enable/disable state, stored in the cache (spec §17.9) — never in the repo. Precedence: DEJAVU_DISABLED env > this state > config.enabled.

store

Local SQLite storage: schema, row models, and the connection facade.

util

Small shared helpers.
