| description | Install and configure RTK (Rust Token Killer) for CLI output compression. Opt-in utility — detects OS, downloads binary, adds to PATH, runs rtk init -g. Invoke with /setup-rtk. |
Optional utility to install RTK — a CLI proxy that compresses Bash command output before it enters the context window. Reduces token consumption by 50-80% on common commands (git, ls, npm, etc.).
This is opt-in. RTK is not required for Crabshell to function. Users invoke /setup-rtk only when they want CLI output compression.
Run: which rtk 2>/dev/null || where rtk 2>/dev/null
rtk --version) and skip to Step 5OS=$(uname -s 2>/dev/null || echo "Windows")
ARCH=$(uname -m 2>/dev/null || echo "x86_64")
Map to RTK release asset name:
| OS | Arch | Asset |
|---|---|---|
| Linux | x86_64 | rtk-x86_64-unknown-linux-gnu.tar.gz |
| Linux | aarch64 | rtk-aarch64-unknown-linux-gnu.tar.gz |
| Darwin | x86_64 | rtk-x86_64-apple-darwin.tar.gz |
| Darwin | arm64 | rtk-aarch64-apple-darwin.tar.gz |
| Windows / MINGW / MSYS | x86_64 | rtk-x86_64-pc-windows-msvc.zip |
If OS/arch combination is not in the table → report and stop.
# Create install directory
mkdir -p "$HOME/tools/rtk"
# Download from GitHub releases (latest)
curl -sL "https://github.com/rtk-ai/rtk/releases/latest/download/{ASSET}" -o /tmp/rtk-download
# Extract
# For .tar.gz: tar -xzf /tmp/rtk-download -C "$HOME/tools/rtk/"
# For .zip: unzip -o /tmp/rtk-download -d "$HOME/tools/rtk/"
# Verify
"$HOME/tools/rtk/rtk" --version # or rtk.exe on Windows
Detect shell config file:
$SHELL contains zsh → ~/.zshrc$SHELL contains bash → ~/.bashrc~/.bashrcCheck if already in PATH config:
grep -q 'tools/rtk' "$SHELL_CONFIG" 2>/dev/null
export PATH="$HOME/tools/rtk:$PATH"rtk init -g
This adds RTK usage instructions to ~/.claude/CLAUDE.md. On Windows, this uses --claude-md mode (text instructions) instead of hook mode.
Tell user:
RTK installed:
- Binary: ~/tools/rtk/rtk (or rtk.exe)
- Version: {version}
- PATH: added to {shell config file}
- Claude Code: ~/.claude/CLAUDE.md updated with RTK instructions
- Mode: {hook (Unix) or claude-md (Windows)}
Next session will automatically use RTK for Bash commands.
To verify: run `rtk --version` in a new terminal.
To uninstall: delete ~/tools/rtk/ and remove the PATH line from {shell config}.
rtk), not hooksRuns Obsidian lint checks on .crabshell/ documents and reports violations. Use when you want to verify document health: missing frontmatter, broken wikilinks, INDEX.md sync issues, orphaned files. Invoke with /lint to run checks, or /lint fix to auto-apply safe fixes.
BM25 full-text search across all D/P/T/I/H/W/K documents in .crabshell/. Returns ranked results by relevance. Use when looking for specific discussions, plans, tickets, or investigations by topic keyword. Invoke with /search-docs <query>.
Creates project-specific verification tools when they don't exist, or runs existing ones against Intent Anchor items. Use when verification is needed and no project verification tool exists. Invoke with /verifying to create verification manifest, or /verifying run to execute existing tools.
Create a Crabshell K knowledge page from Codex. Use for verified facts and operational tips discovered through project work.
Create and run a Crabshell I investigation document from Codex. Use for evidence-heavy research that needs multiple source types, cross-review, and documented conclusions; not for quick questions.
Convert CLAUDE.md instructions into Codex-oriented AGENTS.md guidance. Use when the user wants Claude project rules made available to Codex.
