doctor [--fix] [--json] Run diagnostics (and optionally repair)
safety-levels Show compression safety levels per command
bypass \"command\" Run command with zero compression (raw passthrough)
uninstall Remove shell hook, MCP configs, and data directory
SHELL HOOK PATTERNS (90+):
git status, log, diff, add, commit, push, pull, fetch, clone,
branch, checkout, switch, merge, stash, tag, reset, remote
docker build, ps, images, logs, compose, exec, network
npm/pnpm install, test, run, list, outdated, audit
cargo build, test, check, clippy
gh pr list/view/create, issue list/view, run list/view
kubectl get pods/services/deployments, logs, describe, apply
python pip install/list/outdated, ruff check/format, poetry, uv
linters eslint, biome, prettier, golangci-lint
builds tsc, next build, vite build
ruby rubocop, bundle install/update, rake test, rails test
tests jest, vitest, pytest, go test, playwright, rspec, minitest
iac terraform, make, maven, gradle, dotnet, flutter, dart
utils curl, grep/rg, find, ls, wget, env
data JSON schema extraction, log deduplication
READ MODES:
auto Auto-select optimal mode (default)
full Full content (cached re-reads = 13 tokens)
map Dependency graph + API signatures
signatures tree-sitter AST extraction (18 languages)
task Task-relevant filtering (requires ctx_session task)
reference One-line reference stub (cheap cache key)
aggressive Syntax-stripped content
entropy Shannon entropy filtered
diff Changed lines only
lines:N-M Specific line ranges (e.g. lines:10-50,80)
ENVIRONMENT:
NEBU_CTX_DISABLED=1 Bypass ALL compression + prevent shell hook from loading
NEBU_CTX_ENABLED=0 Prevent shell hook auto-start (nebu-ctx-on still works)
NEBU_CTX_RAW=1 Same as --raw for current command
NEBU_CTX_AUTONOMY=false Disable autonomous features
NEBU_CTX_COMPRESS=1 Force compression (even for excluded commands)
OPTIONS:
--version, -V Show version
--help, -h Show this help
EXAMPLES:
nebu-ctx -c \"git status\" Compressed git output
nebu-ctx -c \"kubectl get pods\" Compressed k8s output
nebu-ctx -c \"gh pr list\" Compressed GitHub CLI output
nebu-ctx token-report --json Machine-readable token + memory report
nebu-ctx wrapped Weekly savings report card
nebu-ctx wrapped --month Monthly savings report card
nebu-ctx sessions list List all CCP sessions
nebu-ctx sessions show Show latest session state
nebu-ctx discover Find missed savings in shell history
nebu-ctx setup One-command setup (shell + editors + verify)
nebu-ctx bootstrap Non-interactive setup + fix (zero-config)
nebu-ctx bootstrap --json Machine-readable bootstrap report
nebu-ctx init --global Install shell aliases (file-based, includes nebu-ctx-on/off)
EVAL INIT (starship/zoxide style — always in sync with binary version):
# bash: add to ~/.bashrc
eval \"$(nebu-ctx init bash)\"
# zsh: add to ~/.zshrc
eval \"$(nebu-ctx init zsh)\"
# fish: add to ~/.config/fish/config.fish
nebu-ctx init fish | source
# powershell: add to $PROFILE
nebu-ctx init powershell | Invoke-Expression
nebu-ctx-on Enable shell aliases in track mode (full output + stats)
nebu-ctx-off Disable all shell aliases
nebu-ctx-mode track Track mode: full output, stats recorded (default)
nebu-ctx-mode compress Compress mode: all output compressed (power users)
nebu-ctx-mode off Same as nebu-ctx-off
nebu-ctx-status Show whether compression is active
nebu-ctx init --agent pi Install Pi Coding Agent extension
nebu-ctx doctor Check PATH, config, MCP, and local edge health
nebu-ctx doctor --fix --json Repair + machine-readable report
nebu-ctx status --json Machine-readable current status
nebu-ctx read src/main.rs -m map
nebu-ctx grep \"pub fn\" src/
nebu-ctx deps .
CLOUD SERVER:
connect [--endpoint <url>] [--token <token>] Save and validate a cloud connection
status Includes cloud connection status
bind Bind the current checkout to a canonical project
disconnect Remove the saved cloud connection
TROUBLESHOOTING:
Commands broken? nebu-ctx-off (fixes current session)
Permanent fix? nebu-ctx uninstall (removes all hooks)
Manual fix? Edit ~/.zshrc, remove the \"nebu-ctx shell hook\" block
Binary missing? Aliases auto-fallback to original commands (safe)
Preview init? nebu-ctx init --global --dry-run
