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

create-prd 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 yesterday.

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.

Output Files

See the ralph-prd skill's SKILL.md "What It Creates" section for the full directory structure. Use templates/ for generating each file.

Implementation

When the user runs /create-prd:

Step 1: Ask for task set name

## Task Set Name

What would you like to name this task set?

Examples: "initial", "auth-feature", "test-coverage"

(Default: "initial" if you press Enter)

Validate the name:

  • Lowercase only
  • Alphanumeric and hyphens only
  • No spaces

Step 2: Check for existing setup

TASKSET_NAME="${1:-initial}"

if [[ -d ".ralph/tasksets/${TASKSET_NAME}" ]]; then
  echo "Task set '${TASKSET_NAME}' already exists."
  echo "Run /ralph taskset switch ${TASKSET_NAME} to use it."
  echo "Or choose a different name."
  exit 0
fi

Step 3: Run discovery questions

Use AskUserQuestion tool for each discovery step:

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.
