## §SELF — miscsubjects capability (paste without context)
**Principle:** Self-explaining payload — no external context required. This _self block is the capability: what it is, how to run it, how to change it, and where to look next.
**Path:** OIP > AGENT > AGENT_SPAWN
**Capability:** `AGENT_SPAWN` — Spawn a resident agent that loops on a goal until done (durable, survives Mac sleep)
**When to use:** you need to agent spawn
**RUN NOW (open this URL):** https://miscsubjects.com/api/dispatch?invoke=AGENT_SPAWN&body=%3Cgoal%3E%7C%3Cbrain%3E%7C%3CmaxSteps%3E&share=<TOKEN>
**Example call:** [AGENT_SPAWN]<goal>|<brain>|<maxSteps>[/AGENT_SPAWN]
- **type · runner:** agent · edge · agent
- **run it:** Open run_now (URL, fires the example), or POST https://miscsubjects.com/api/dispatch {"key":"AGENT_SPAWN","body":"<goal>|<brain>|<maxSteps>"}. From the router: [AGENT_SPAWN]arg1|arg2|arg3[/AGENT_SPAWN]
- **inputs:** {"args":"goal|brain|maxSteps"}
- **outputs:** { ok, result, invocation, yield, _self } — result is this object's output; yield is tokens/cost/material; invocation is the ledgered record.
- **auth · risk:** none · low
### Machine Contract
- Read this article first; do not infer the row shape from memory.
- If acting with a URL-only tool, open run_now after replacing placeholder args.
- If the call returns ran:false or proof.ok:false, read the receipt and repair the failed invocation instead of narrating success.
- If the token denies the call, report the denial exactly; do not switch to a broader action unless the owner supplied a broader token.
### Invocation, Ledger, Repair
- root tree: https://miscsubjects.com/api/dispatch?map=1&format=markdown
- parent system article: https://miscsubjects.com/api/dispatch?map=AGENT&format=markdown
- append-only ledger: https://miscsubjects.com/api/invocations?object_id=AGENT_SPAWN
- receipt pattern: https://miscsubjects.com/api/dispatch?receipt=inv_ID&share=<TOKEN>
- replay: POST /api/dispatch {"replay":"inv_ID"}
- repair: POST /api/dispatch {"key":"AGENT_SPAWN","body":"corrected args","repairs":"inv_ID"}
### Troubleshooting
- **unknown key** — Use the did_you_mean links or ask URL; never guess another key. · https://miscsubjects.com/api/dispatch?ask=AGENT_SPAWN
- **argument/body mismatch** — Read inputs/example_args here, then retry with repairs: inv_ID so lineage closes. · https://miscsubjects.com/api/dispatch?key=AGENT_SPAWN
- **expired or corrupted token** — Report token_expired/token_corrupted from the response; owner mints a fresh scoped link. · https://miscsubjects.com/api/dispatch?explain=1&share=<TOKEN>
- **tool returned ok:false / exit nonzero** — Do not call it sent. Read the receipt, correct the body, fire a repair. · https://miscsubjects.com/api/dispatch?receipt=inv_ID&share=<TOKEN>
### Logical proof (verify each step)
1. Every capability is an invokable object with its own _self — this block. → https://miscsubjects.com/api/dispatch?key=AGENT_SPAWN
2. You run it by POSTing to /api/dispatch; in a model turn the router tag is [AGENT_SPAWN]args[/AGENT_SPAWN]. → https://miscsubjects.com/api/dispatch?registry=1
3. Every invocation is ledgered with actor, cost, and material/waste. → https://miscsubjects.com/api/invocations?object_id=AGENT_SPAWN
4. You can ask the build for capabilities in plain language. → https://miscsubjects.com/api/dispatch?ask=Spawn%20a%20resident%20agent%20that%20loops%20on%20a%20g
5. The whole build is one self-describing map, with the terminal key. → https://miscsubjects.com/api/dispatch?build=1

- **history** — This capability's invocation history — its edges · https://miscsubjects.com/api/invocations?object_id=AGENT_SPAWN
- **build** — The whole build as one map (terminal key) · https://miscsubjects.com/api/dispatch?build=1
