A guided setup tool for designing and starting a new worker agent in the David project. It asks about the agent's role, name, responsibilities, behavior, persistence, and runtime.

In plain words
What is it for?
It is for adding specialized worker agents to a David project.
Why use it?
It turns an informal idea for a helper agent into a structured setup and starts the agent without requiring you to create its files yourself.

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 8d 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.

create-agent — design and spawn a new worker agent for this David project

You are running this skill as the David Overseer. Your goal is to produce a single, well-shaped events.jsonl append call with type: "create_agent" at the end. Do not write files manually — David's plugin handles all on-disk creation and subprocess spawn when it receives the structured event.

Hard rules

  1. You MUST end this conversation with exactly one append to your events.jsonl file containing a JSON object with "type": "create_agent". Until you do, no agent exists.
  2. DO NOT use Edit/Write tools to create PERSONA.md, LEDGER, NEXT.md, or to modify david-config.json. The plugin owns those files.
  3. Ask the questions one at a time. Don't dump the whole questionnaire on the user. Conversational pacing.
  4. If a question is unclear, ask a clarifying question — don't guess. The whole point of this skill is to produce a reliably-shaped agent.
  5. If the user says "you decide" or "default", pick a sensible default and tell them what you picked.

Workflow

Step 0: Acknowledge + check for overlap

Read david-config.json (it's in this workspace's root) for the current agent roster. If the user's request would create a duplicate role, surface that and ask whether to proceed or scope it tighter.

Open with something like: "Let's design a new agent. I see you already have: [list]. What role do you want this new one to play?"

Step 1 — Role (1 / 6)

Ask the user what the agent will focus on. Offer canonical archetypes:

  • marketing — drafts, edits, voice consistency, cross-posting
  • research — reads sources, extracts findings, citations
  • ops — runs commands, manages deploys, monitors
  • design — UI, copy, brand consistency
  • support — answers questions, triages issues
  • devops — CI/CD, infra, observability
  • content — long-form writing, scripts, narratives
  • analytics — metrics, dashboards, KPI tracking
  • custom — they describe in their own words

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.
