Fields

ultra_compact: bool

tee_mode: TeeMode

output_density: OutputDensity

checkpoint_interval: u32

excluded_commands: Vec<String>

passthrough_urls: Vec<String>

custom_aliases: Vec<AliasEntry>

slow_command_threshold_ms: u64

Commands taking longer than this threshold (ms) are recorded in the slow log. Set to 0 to disable slow logging.

theme: String

cloud: CloudConfig

autonomy: AutonomyConfig

buddy_enabled: bool

redirect_exclude: Vec<String>

disabled_tools: Vec<String>

Tools to exclude from the MCP tool list returned by list_tools. Accepts exact tool names (e.g. [“ctx_graph”, “ctx_agent”]). Empty by default — all tools listed, no behaviour change.

loop_detection: LoopDetectionConfig

rules_scope: Option<String>

Controls where lean-ctx installs agent rule files. Values: “both” (default), “global” (home-dir only), “project” (repo-local only). Override via LEAN_CTX_RULES_SCOPE env var.

extra_ignore_patterns: Vec<String>

Extra glob patterns to ignore in graph/overview/preload (repo-local). Example: [“externals/”, “target/”, “temp/**”]

terse_agent: TerseAgent

Controls agent output verbosity via instructions injection. Values: “off” (default), “lite”, “full”, “ultra”. Override via LEAN_CTX_TERSE_AGENT env var.

archive: ArchiveConfig

Archive configuration for zero-loss compression.

allow_paths: Vec<String>

Additional paths allowed by PathJail (absolute). Useful for multi-project workspaces where the jail root is a parent directory. Override via LEAN_CTX_ALLOW_PATH env var (path-list separator).

content_defined_chunking: bool

Enable content-defined chunking (Rabin-Karp) for cache-optimal output ordering. Stable chunks are emitted first to maximize prompt cache hits.

minimal_overhead: bool

Skip session/knowledge/gotcha blocks in MCP instructions to minimize token overhead. Override via LEAN_CTX_MINIMAL env var.

shell_hook_disabled: bool

Disable shell hook injection (the _lc() function that wraps CLI commands). Override via LEAN_CTX_NO_HOOK env var.
