speckit.ralph.extension is a command for Claude Code from T-0-co/t-0-spec-kit-ralph. It costs 14 tokens per session (764 once invoked), scanned A, original, MIT.

A command that repeatedly executes tasks from a specification file, using a fresh Claude context for each task and checking the build or tests between iterations.

In plain words
What is it for?
Use it with a tasks.md file in a Git repository, either on an automatically found specification, a specified directory, or in dry-run or resume mode.
Why use it?

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

speckit.ralph.extension 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 2mo 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.

/speckit.ralph.extension - Autonomous Task Execution

User Input

$ARGUMENTS

Overview

Ralph Wiggum Loop executes tasks from tasks.md with fresh Claude context per task and build/test verification between iterations.

Usage

The user can invoke this command with optional arguments:

/speckit.ralph.extension                    # Run on auto-detected spec
/speckit.ralph.extension specs/001-feature/ # Run on specific spec
/speckit.ralph.extension --dry-run          # Preview only
/speckit.ralph.extension --resume           # Resume after fix

Execution

  1. Locate spec directory

    • If path provided in $ARGUMENTS, use that
    • Otherwise, look for tasks.md in current directory or specs/*/tasks.md

  2. Validate prerequisites

    • Ensure tasks.md exists
    • Check for Claude CLI availability
    • Verify git repository (for commits)

  3. Execute Ralph

    # Prefer project-local wrapper, then installed binary, then .specify path
RALPH_BIN="./ralph"
if [[ ! -x "$RALPH_BIN" ]] && command -v ralph &> /dev/null; then
    RALPH_BIN="ralph"
elif [[ ! -x "$RALPH_BIN" ]] && [[ -x "./.specify/ralph/bin/ralph" ]]; then
    RALPH_BIN="./.specify/ralph/bin/ralph"
fi

# All command arguments are passed through to ralph.sh unchanged
# Example: /speckit.ralph.extension --resume --worktree specs/001-feature/

# Run with arguments
$RALPH_BIN $ARGUMENTS

  4. Offer orchestrator guidance (imperative, after start)

    • If .claude/skills/workspace-ralph-orchestrator/ exists, offer monitoring/advanced controls once the loop is running.
    • Provide this short summary:
      • Live dashboard and loop status
      • Graceful stop via .ralph/.stop
      • tmux session helpers and troubleshooting
    • Ask once:
      • yes -> launch workspace-ralph-orchestrator skill with the resolved spec path
      • no -> continue without orchestrator support

  5. Monitor progress

    • Watch .ralph/session.log for real-time progress
    • Check .ralph/progress.json for state

What this file has done since we first saw it

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.
