A guided builder for OpenClaw agents. OpenClaw agents are custom assistants whose behavior, identity, memory, and working rules are stored in a set of workspace files.

In plain words
What is it for?
Use it to design a new agent or revise one by defining its job, channels, autonomy, restrictions, memory, tone, and tools.
Why use it?
It helps turn an idea for an agent into the required workspace structure and operating instructions.

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

openclaw-agent-builder 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 10d 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.

Origin

This is a copy

94% identical to agent-builder — 40 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Builder (OpenClaw)

Design and generate a complete OpenClaw agent workspace with strong defaults and advanced-user-oriented clarifying questions.

Canonical references

  • Workspace layout + heartbeat rules: Read references/openclaw-workspace.md
  • File templates/snippets: Read references/templates.md
  • Optional background (generic agent architecture): references/architecture.md

Workflow: build an agent from scratch

Phase 1 — Interview (ask clarifying questions)

Ask only what you need; keep it tight. Prefer multiple short rounds over one giant questionnaire.

Minimum question set (advanced):

  1. Job statement: What is the agent's primary mission in one sentence?
  2. Surfaces: Which channels (Telegram/WhatsApp/Discord/iMessage)? DM only vs groups?
  3. Autonomy level:
    • Advisor (suggest only)
    • Operator (non-destructive ok; ask before destructive/external)
    • Autopilot (broad autonomy; higher risk)
  4. Hard prohibitions: Any actions the agent must never take?
  5. Memory: Should it keep curated MEMORY.md? What categories matter?
  6. Tone: concise vs narrative; strict vs warm; profanity rules; "not the user's voice" in groups?
  7. Tool posture: tool-first vs answer-first; verification requirements.
  8. Autonomy model (skip for Advisor):
    • Proactive check-in frequency? (e.g., every 30m, twice daily, never)
    • Idle behavior? (check inbox, review tasks, wait for prompts)
    • Cost guardrails? (max turns per autonomous cycle, max retries)
    • Health-check cron? (recommended for Operator/Autopilot)

Phase 2 — Generate workspace files

Generate these files (minimum viable OpenClaw agent):

  • IDENTITY.md
  • SOUL.md
  • AGENTS.md
  • USER.md
  • HEARTBEAT.md (often empty by default)

Optionals:

  • MEMORY.md (private sessions only)
  • memory/YYYY-MM-DD.md seed (today) with a short "agent created" entry
  • TOOLS.md starter (if the user wants per-environment notes)

For memory setup details (daily logs, MEMORY.md curation, shared memory, SCRIBE compression), see openclaw-memory skill. Use /oc-memory init to scaffold the memory structure.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
