_create-agent

_create-agent is a skill for Claude Code from flavien-ia/hypervibe-harness. It costs 53 tokens per session (6,703 once invoked), scanned A, original, Apache-2.0.

A helper for setting up an autonomous AI agent, meaning a program that can pursue a goal and use selected tools without being guided at every step.

In plain words
What is it for?
It helps create agents that run on a schedule, continuously, or when started manually.
Why use it?
It provides a defined budget, limits, optional memory, and a record of the agent's work so autonomous runs can be controlled and reviewed.

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-agent 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 495 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ Before any call to the script (to do BEFORE any other command in this skill)

# Detect the project's root organization
node "${CLAUDE_SKILL_DIR}/../../scripts/wrangler-env-init.mjs" 2>/dev/null

(Not strictly required here, but handy if you hit a case where Wrangler is needed - typically not.)

Create Agent - Scaffold an autonomous AI agent

The brief you are invoked with

You are never reached by a user typing a command: add-automation (or add-ai) has already established that this need has a real agentic loop or genuine autonomy, and that neither a workflow nor a routine fits. Do not re-run that decision. It hands you:

Field What it carries
GOAL what the agent must accomplish, in the user's words
TRIGGER cron / continuous / manual
VOLUME how often it runs

Q1 below is therefore already answered: restate the goal in one line and move to Q1.bis. The remaining questions (memory, budget, tools, allowlists) are yours to ask, because they have no equivalent upstream.

Communication

  • Detect the user's language from the conversation (the user's own messages, anywhere in the session - not just this invocation: a bare slash command like /bootstrap carries no language signal by itself). If nothing in the conversation gives a signal, fall back to the OS locale (node -e "console.log(Intl.DateTimeFormat().resolvedOptions().locale)") before defaulting to English. ALWAYS reply in that language for every user-facing message: questions, progress, confirmations, summaries, errors - including any example text quoted in this skill, which is illustrative and must be translated, never sent verbatim.
  • Use plain, non-technical business language. Never expose internal script names (*.mjs) or jargon; describe actions in human terms.
  • When generating user-facing content for the scaffolded project (UI labels, emails, copy), write it in the user's language too.
  • Show progress as a short natural-language checklist (in-progress and done states).

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.
