tutorial-guide-agent-runtime

tutorial-guide-agent-runtime is a skill for Claude Code, Codex from Lingtai-AI/lingtai. It costs 39 tokens per session (1,013 once invoked), scanned A, original, Apache-2.0.

A tutorial reference for lessons about starting and running agents. It explains configuration in init.json, the lingtai-agent run command, heartbeat and signal files, a text-based interface, and the agent's system-prompt identity.

In plain words
What is it for?
Use it to teach or follow lessons on creating an agent, explaining its configuration, starting it, monitoring its signals, and understanding how its identity is set.
Why use it?
It gives learners a practical way to understand the runtime by reading the real configuration and running the real command, instead of memorising a list of settings.

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

tutorial-guide-agent-runtime 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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tutorial Guide — Agent Runtime Lessons

Nested tutorial-guide reference for agent runtime lessons 4–6, reached from the root tutorial-guide router. Teach live per the router's discover, don't recite rule: read the real file or run the real command before explaining it.

Lesson 4: How Agents Are Born — init.json and lingtai-agent run

Part 1: init.json

Read YOUR init.json and walk through every field you find. Do not recite a list of fields — read the file and explain what is there. The human sees the real structure.

Key patterns to explain:

  • The _file convention: live init fields like covenant, pad, comment, base_prompt take inline text or a <field>_file path to a shared file. (Older fields such as principle, procedures, brief, soul, and the legacy prompt are migrated by the kernel but no longer seeded here.) Note: there is no seed field for the agent's character in init.json — character is durable state the agent authors for itself after creation, managed via system/lingtai.md / psyche, not written into init.json.
  • manifest contains: llm, agent_name, language, capabilities, soul, admin, etc.
  • addons connects to external messaging services.
  • env_file for secrets.

Part 2: lingtai-agent run

Explain the boot sequence: read init.json → load env → resolve venv → build Agent → clean stale signals → install signal handlers → start in ASLEEP state → agent.start() blocks on shutdown.

Emphasize: the agent is a long-running Python process. It does not exit after one task.

Part 3: Heartbeat and signal files

Show your own .agent.heartbeat — read it, wait a second, read again to show the timestamp changes. Explain the signal files: .interrupt, .suspend, .sleep, .prompt.

Lesson 5: The TUI — How lingtai-tui Wraps the Agent Runtime

Explain: lingtai-tui is a Go frontend, not the agent. It creates agents (writes init.json), launches them (python -m lingtai run), monitors them (.agent.heartbeat, .agent.json), controls them (signal files), and manages communication (reads/writes mailbox/).

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.
