Put Piggy on Prime Agent, and let it write to the book
Piggy was a hand-rolled OpenAI tool loop. It is now a Prime Agent session — Prime Intellect's own harness, embedded as a Node library — answering from PIG's tools and, for the first time, able to put information into the CRM rather than only read it out. The harness is a coding agent, so the first job was taking the coding agent away from it. `noTools: 'all'` plus an explicit allowlist leaves the model with PIG's ten `pig_*` tools and no bash, no filesystem, no IPython. That holds under attack: a hostile extension, a skill and a settings file planted in the agent's own directory, then `setActiveToolsByName` called with every built-in, still leaves ten tools, all ours. Both lines are load-bearing — `noTools` alone registers nothing, and the allowlist is what admits our own. Writing is gated rather than assumed. A change is proposed, not made: the tool returns a description, the transcript renders a diff card, and nothing reaches the database until someone presses Apply. Contracts, commitments, allocations and compliance always stop for a human whatever the mode. Every write runs through `executeMutation` as the calling user, so their capabilities and the audit trail apply exactly as they would to a human's. Four things about the SDK are wrong in its own documentation and cost a debugging cycle each: models.json does not resolve an env var name for `apiKey`, it sends the literal string; there is no built-in prime-inference provider in 0.84.1; a ResourceLoader you pass in is never reloaded for you; and the stock system prompt is a coding-assistant prompt that must be replaced — but replacing it also silently removes the tool list, because the harness only renders that section when it owns the prompt. AGENTS.md records all four. The expensive one was thinking level. The harness defaults to `medium`, and nemotron spent an entire 4,096-token budget reasoning and returned an empty answer. `low` was worse; `off` omits the parameter so the endpoint's default wins. An explicit `reasoning_effort: none` via `thinkingLevelMap` took a turn from 6,195 output tokens to 149. And a turn is now bounded. The harness loop is `while (true)` with no iteration cap; a runaway on a frontier model would have eaten the credit it is supposed to report on. Ceilings on model calls and tokens, enforced both through the harness hook and independently from the event stream, plus a per-user daily spend limit — and the ledger now records spend on turns that fail, which it previously discarded. Signing in lands on /piggy, which is a workspace: conversations down one side, the agent in the middle, what it did and what it cost beside it.

/**
|

* An in-memory transcript store, for driving the relay without a database.
|
||||
*
|
||||
* The relay's job is now half persistence, and the properties worth asserting
|
||||
* about it are about ORDER and ABOUT FAILURE: the question is filed before the
|
||||
* answer, tool evidence lands as it streams, and a store that throws must not
|
||||
* be able to reach the stream the user is reading. None of that needs SQL, and
|
||||
* a real Postgres would make it harder to assert — `failOn` here fails a
|
||||
* specific method on demand, which is the case that matters most and the one a
|
||||
* live database will not perform to order.
|
||||
*
|
||||
* What it is NOT is a second implementation of the store's semantics. Ownership
|
||||
* predicates, `seq` under concurrency and the capability gate are asserted
|
||||
* against a real database in piggy-conversations.test.ts, because that is where
|
||||
* they are either true or not.

* not, the route above it keeps working perfectly for its author and quietly
|

* So the assertions are made twice, at two different depths:
|
||||
*
|
||||
* - against a recording driver, which runs in the default suite and pins
|
||||
* that the predicate actually reaches SQL on every path, including the
|
||||
* ones a fake row store would happily let through;
|
||||
* - against a real Postgres, which is where a cascade, a unique key and a
|
||||
* CHECK constraint are either true or not. That half needs a database and
|
||||
* therefore names its own:
|
||||
*
|

* createdb pig_piggy_test
|

* DATABASE_URL=postgres://…/pig_piggy_test pnpm -F @pig/db run migrate

* PIG_TEST_DATABASE_URL=postgres://…/pig_piggy_test \
|

* pnpm -F @pig/api run test
|

*
|

* A deliberately separate variable from `DATABASE_URL`: this suite writes
|

* and deletes rows, and it must be impossible to point it at a working
|
||||
* database by inheriting the environment.
