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.

|

* was the ONLY copy of a conversation anyone could reach.
|

*
|

* Now that transcripts persist properly the contradiction has no excuse left,

* and it is settled the way the conversation store settles it. An admin keeps
|

* everything they need — what ran, whose it was, whether it failed, what it
|
||||
* cost, how long it took — and loses the two fields that are somebody's private
|
||||
* questions about the book. An admin reading their OWN runs sees them in full,
|
||||
* as does everybody else, because `runs` scoped to a caller returns no
|
||||
* `principal` on their own rows: that field is populated only when the run
|
||||
* belongs to somebody else, which makes it the exact signal this needs.
|
||||
*
|
||||
* It sits in the route rather than the service on the reasoning this file
|

* opened with — the service computes the ledger, the route is the gate — and

* because `overview` has one caller. Should a second appear, this moves down.
|
||||
*
|
||||
* One case is deliberately left open, and is written down rather than left to
|
||||
* be discovered. `agent_runs.principal_user_id` is `ON DELETE set null`, so a
|
||||
* departed colleague's runs survive with no owner, and the service reports an
|
||||
* ownerless run exactly as it reports the caller's own: `principal: null`. To
|
||||
* an administrator those two are indistinguishable from here, so a leaver's
|
||||
* questions stay legible while a current colleague's do not. Closing it needs
|
||||
* `PiggyRunSummary` to say whose a run is not, rather than only when it is
|
||||
* somebody else's — a change in the service, and the wrong thing to guess at

* Two rules hold everywhere in this file.
|

*
|
||||
* **Ownership is a predicate, never a check after the fact.** Every statement
|
||||
* carries `user_id = $me`, so another person's conversation and a UUID that
|
||||
* does not exist are the same answer: nothing. Reading a row and then
|
||||
* comparing its owner would work equally well until the day someone adds a
|
||||
* path that forgets the comparison, and that path would return the row.
|
||||
*
|
||||
* **A platform admin is not an exception.** Everywhere else in PIG being an
|
||||
* administrator widens what you can see, and here it must not: a transcript is
|
||||
* a person's own half-formed questions about the book, and nobody asked to
|
||||
* have it read. Cost and audit live in `agent_runs` and `activities`, which is
|
||||
* where an administrator looks.
|
||||
*
|
||||
* Writes here do NOT go through `executeMutation`, which is otherwise the
|
||||
* chokepoint for every write in the API. That convention exists to enforce
|
||||
* capabilities and to write an audit activity, and both reasons are absent: a
|
||||
* conversation is scoped to its owner rather than to a team, and an activity
|
||||
* row per message would put "Started a Piggy conversation" into the account
|
||||
* feed and the dashboard's recent activity dozens of times a day, drowning the
|
||||
* log the convention exists to keep readable. The writes Piggy performs ON THE

|
||||
* forgets it on reload, the agent streams it and keeps nothing — so this is
|
||||
* where the record is made. It exists because `piggy_messages` was never
|
||||
* written: the sidebar listed twelve conversations against zero messages, and a
|
||||
* thread reopened the next day was a title and nothing else.
|
||||
*
|
||||
* Three rules hold in here, and each one is a bug that would otherwise be
|
||||
* shipped.
|
||||
*
|
||||
* **Nothing thrown here may reach the stream.** Every append is swallowed and
|
||||
* logged. The answer is what the user asked for; losing the filing is a
|
||||
* disappointment, losing the answer to a failed INSERT is an outage. `absorb`
|
||||
* and `observe` are therefore synchronous and total: they mutate local state
|
||||
* and enqueue, and cannot reject into the pipe loop.
|
||||
*
|
||||
* **Writes are serialised.** `appendMessage` assigns `seq` inside a transaction
|
||||
* against a locked conversation row, so racing appends cannot collide — but
|
||||
* they could still land in the wrong ORDER, and a transcript whose tool
|
||||
* evidence sorts above the question it answered is not a transcript. One
|
||||
* promise chain, appended to, keeps the order the stream had.
|
||||
*
|
||||
* **Tool rows are evidence, and evidence is written when it lands.** The
|
||||
* product's claim is that you can see the records behind an answer. A tool row
|
||||
* is flushed at its result rather than held until the end, so a turn whose
|
||||
* connection dies half-way still leaves what it read behind. The assistant's
|
||||
* text is the one row written last, because it is assembled from deltas.

/**

* That a Piggy transcript belongs to exactly one person.

*
|

* The failure this suite exists to prevent is not exotic. Every statement in
|

* `PiggyConversationService` carries `user_id = $me`; the day one of them does
|
||||
* not, the route above it keeps working perfectly for its author and quietly
|
||||
* starts answering for everybody else's history too, with no error anywhere.
|
||||
* 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.
