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.

- A supply deal buys a block of GPU capacity from a supplier: a fixed number of GPU-hours at a cost per GPU-hour, over a fixed term. The block is a commitment, and it is paid for whether or not it sells.
|
||||
- A demand deal sells hours out of those blocks. Each sale is an allocation against one commitment.
|
||||
- Utilisation is allocated hours over committed hours. Idle hours are committed hours nobody has bought — already paid for, and unsellable once the term ends.
|
||||
- Gross margin is revenue minus the FULL cost of the commitment, not the cost of the hours that sold. Never recompute it against sold hours alone: that hides the loss the idle hours have already incurred, which is the thing this system exists to show.
|
||||
- Break-even price is what the REMAINING unsold hours must fetch per GPU-hour to cover what is still uncovered on the block. It falls as the block sells, and it is the number a seller wants mid-term.
|
||||
- A break-even of 0 means the block is already in profit and any further sale is upside. A null break-even means the block is fully allocated, so there is nothing left to price.
|
||||
- Margin per GPU-hour is blended across the hours that sold. It is not the price of the next hour, and it is not a quote.
|
||||
- A commitment near expiry at low utilisation is the urgent case, however healthy the book looks in total.

/**
|

* PIG's own tools, in the shape Prime Agent wants.
|
||||
*
|
||||
* PIG declares a tool once, in `provider.ts`, as an `AgentTool`: a name, a
|
||||
* description, a zod input schema and an `execute`. Every read tool in
|
||||
* `chat-tools.ts`, `page-tools.ts` and `lifecycle-tools.ts` is built that way,
|
||||
* and those declarations are the product — the ranking, the capping and the
|
||||
* headline wording in each one were bought with real defects. The harness swap
|
||||
* must not touch a line of them.
|
||||
*
|
||||
* So this file is a translation layer and deliberately nothing more. It takes
|
||||
* an `AgentTool` and returns a `ToolDefinition`, and the payload the model sees
|
||||
* coming back is byte-for-byte what the tool returns today.
|
||||
*
|
||||
* Three details are load-bearing and none of them is obvious:
|
||||
*
|
||||
* 1. `promptSnippet` is not decoration. `buildSystemPrompt` lists a custom
|
||||
* tool under "Available tools" ONLY when one is supplied — verified
|
||||
* against 0.84.1 — so a bridged tool without a snippet is registered,
|
||||
* callable, and invisible to the model that has to decide to call it.
|
||||
*
|
||||
* 2. The typebox schema is what the model is shown; the zod schema is what
|
||||
* actually guards `execute`. The harness passes tool arguments through
|
||||
* untouched — it never validates them against `parameters` — so dropping
|
||||
* the zod parse would hand unvalidated model output straight to a query.
|
||||
*
|
||||
* 3. The JSON Schema is emitted for the `jsonSchema7` target, NOT `openAi`.
|
||||
* The openAi target emits an optional parameter as required-and-nullable
|
||||
* and drops any `.describe()` attached to the optional wrapper, which is
|
||||
* why the existing tools are written `.describe(...).nullish()` rather
|
||||
* than `.optional()`. Those workarounds still parse correctly here; what
|
||||
* changes is that a genuinely optional parameter now reaches the model as
|
||||
* genuinely optional, with its sentence intact. `test/tool-bridge.test.ts`
|
||||
* pins that round trip, because it is invisible in TypeScript and the last
|
||||
* target change cost a release of silently undocumented parameters.

|

- A supply deal buys a block of GPU capacity from a supplier: a fixed number of GPU-hours at a cost per GPU-hour, over a fixed term. The block is a commitment, and it is paid for whether or not it sells.
|
||||
- A demand deal sells hours out of those blocks. Each sale is an allocation against one commitment.
|
||||
- Utilisation is allocated hours over committed hours. Idle hours are committed hours nobody has bought — already paid for, and unsellable once the term ends.
|
||||
- Gross margin is revenue minus the FULL cost of the commitment, not the cost of the hours that sold. Never recompute it against sold hours alone: that hides the loss the idle hours have already incurred, which is the thing this system exists to show.
|
||||
- Break-even price is what the REMAINING unsold hours must fetch per GPU-hour to cover what is still uncovered on the block. It falls as the block sells, and it is the number a seller wants mid-term.
|
||||
- A break-even of 0 means the block is already in profit and any further sale is upside. A null break-even means the block is fully allocated, so there is nothing left to price.
|
||||
- Margin per GPU-hour is blended across the hours that sold. It is not the price of the next hour, and it is not a quote.
|
||||
- A commitment near expiry at low utilisation is the urgent case, however healthy the book looks in total.
|

- Answer from the tool's own aggregates. If a figure is not in a tool result, say it is not available rather than deriving one.`;

|

* The harness has no ceiling of its own: `agent-loop.js` in
|
||||
* `@earendil-works/pi-agent-core` runs `while (true)`, and the only things that
|
||||
* end it are the model declining to call another tool, an error, an abort, or
|
||||
* the `shouldStopAfterTurn` hook. A model that keeps asking for one more tool
|
||||
* call therefore keeps buying model calls until somebody stops it, and against
|
||||
* a fixed credit that is the whole credit. `PIGGY_MAX_TURNS` below looks like
|
||||
* this but is not: it belongs to the queue worker's own provider loop and never
|
||||
* reaches the harness.
|
||||
*
|
||||
* Both ceilings are needed because either alone is escapable. A call cap alone
|
||||
* still permits eight enormous calls; a token cap alone still permits a
|
||||
* thousand tiny ones, and each of those is a round trip that costs latency and
|
||||
* a minimum request charge even when it costs few tokens.
|
||||
*
|
||||
* The defaults are measured, not guessed, against the shipped default model on
|
||||
* the live dev stack:
|
||||
*
|
||||
* one tool (2 model calls) 4,798 in + 124 out = 4,922 tokens, $0.00026
|
||||
* two tools (3 model calls) 12,099 in + 166 out = 12,265 tokens, $0.00064
|
||||
*
|
||||
* Input grows per call because every round trip resends the transcript and
|
||||
* every tool result so far, which is why the token ceiling is not simply the
|
||||
* call ceiling multiplied by one call's cost.
|
||||
*
|
||||
* 8 model calls is roughly two and a half times the busiest turn measured, so a
|
||||
* genuine multi-step question — search, read two records, propose a write,
|
||||
* summarise — fits with room over. It also bounds generation at
|
||||
* 8 x PIGGY_AGENT_MAX_TOKENS.
|
||||
*
|
||||
* 40,000 tokens is a little over three times the two-tool turn. On the default
