rtk: Command for Claude Code

.claude/commands/test-routing.md

test-routing is a command for Claude Code from rtk-ai/rtk. It costs 17 tokens per session (2,223 once invoked), scanned A, original, Apache-2.0.

A dry-run command that checks whether RTK, a tool that shortens command output, has a filter for another command without running it.

In plain words
What is it for?
Use it to check commands such as `git status`, `npm install`, or `cargo test` before running them, and to debug command-routing hooks.
Why use it?
It shows how a command would be routed and avoids side effects while you test the setup.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; positional $N argument; mentions Claude Code.

This is rtk-ai/rtk's own configuration. It tells Claude Code how to work on rtk itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything rtk configures →

About the project

rtk is a command-line proxy that filters and compresses output from development commands before it reaches an LLM's context. It is used with coding agents to reduce the tokens consumed by commands such as Git operations. The catalogue includes skills, commands, agents, and instructions for using rtk in agent workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-routing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/test-routing

Vérifie le routing de commandes RTK sans exécution (dry-run). Utile pour tester si une commande a un filtre disponible avant de l'exécuter.

Usage

/test-routing <command> [args...]

Exemples

/test-routing git status
# Output: ✅ RTK filter available: git status → rtk git status

/test-routing npm install
# Output: ⚠️  No RTK filter, would execute raw: npm install

/test-routing cargo test
# Output: ✅ RTK filter available: cargo test → rtk cargo test

Quand utiliser

  • Avant d'exécuter une commande: Vérifier si RTK a un filtre
  • Debugging hook integration: Tester le command routing sans side-effects
  • Documentation: Identifier quelles commandes RTK supporte
  • Testing: Valider routing logic sans exécuter de vraies commandes

Implémentation

Option 1: Check RTK Help Output

shift
ARGS="$@"

# Check if RTK has subcommand for this command
if rtk --help | grep -E "^  $COMMAND" >/dev/null 2>&1; then
    echo "✅ RTK filter available: $COMMAND $ARGS → rtk $COMMAND $ARGS"
    echo ""
    echo "Expected behavior:"
    echo "  - Command will be filtered through RTK"
    echo "  - Output condensed for token efficiency"
    echo "  - Exit code preserved from original command"
else
    echo "⚠️  No RTK filter available, would execute raw: $COMMAND $ARGS"
    echo ""
    echo "Expected behavior:"
    echo "  - Command executed without RTK filtering"
    echo "  - Full command output (no token savings)"
    echo "  - Original command behavior unchanged"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
