What we learned in the Forge

Patterns from building agents that integrate with existing teams and systems — the working assumptions the Forge's first experiments are designed to test, and what writing those experiments made clear.

  • The Forge · field note

The Forge is the Guild's research bench: model comparisons, reliability tests, cost experiments and workflow simulations. Its first four experiments are now written up as protocols. None of them has results yet.

So the title deserves care. This note is not a results report, and it does not pretend to be one. It records two things: the patterns the Guild designs for when an agent has to join an existing team and its systems — the working assumptions the Forge's experiments are built to test — and what writing those experiments has already made clear. When results arrive, this note will be revised to say where each pattern held and where it did not.

Status — Field note. No Forge experiment has results yet. The patterns below are design assumptions under test, not findings.

01

How the Forge works: the protocol comes first

An experiment in the Forge starts as a page, not a run. The page states the question, the hypotheses, the method, and — before any data exists — what result would confirm each hypothesis and what would refute it. A few rules apply to every protocol:

A wizard seals a brass casket with wax beside an unlit glass experiment cylinder, a hooded cyan figure holding a candle.
  • Thresholds before data. What counts as "clearly better" is written down before the first run, so results cannot be read to fit.
  • Everything versioned. Model, instructions, tools, knowledge and scenarios are recorded with every result. Without that, two results cannot be compared.
  • Rules before model graders. Whatever can be decided from the logs is decided by a rule. Model graders are kept for what rules cannot see, and calibrated against people first.
  • More than one run. Agents are not deterministic, so a scenario passes only if it passes repeatedly — τ-bench's pass^k (Yao et al., 2024) rather than a single lucky run.
  • Every result is reported. Negative and inconclusive results go on the page in the same form as positive ones.
  • Status on every page. A reader can always tell whether they are looking at a protocol or a result.

041 — Multi-agent evaluation frameworkIs scoring each agent alone enough when agents share a mission?Protocol; no results yet
038 — Agent memory architecturesWhich memory design gives recall without stale, leaked or poisoned memory?Protocol; no results yet
037 — Retrieval augmentation for operationsWhich retrieval set-up gives answers that are correct, cited, current and permitted?Protocol; no results yet
Measuring agent productivity beyond tokensDo token and activity counts say anything about the value of an agent's work?Oracle's research; protocol; no results yet

Patterns we design for

Agents rarely arrive in an empty room. They join a team with its own habits and a set of systems that were there first. These are the patterns the Guild builds around in that situation. Each is a working assumption, and the table says where the Forge puts it to the test.

Four cyan figures pass a glowing baton along an arcade, and it drops to the floor between two of them as a wizard waits.
PatternWhy we design for itWhere it is tested
Start from the work and its owner, not the agentAn agent multiplies whatever process it joins, including a bad oneNot on its own: it is the precondition of every protocol, each of which defines "correct" before measuring
The system of record winsCopied records go stale; memory that disagrees with the CRM is wrong037 (routing record questions to live systems), 038 (record precedence)
Intake sets the ceilingEvery step downstream inherits what intake got wrongNot yet in a Forge experiment; Athena describes the downstream signals to watch
Hand-offs are where integrations breakAgents that pass work on can each be right while the mission fails041 (seeded hand-off defects, hand-off contracts)
Retrieved and remembered text is data, not instructionsDocuments and old messages can contain text that tries to steer the agent038 (poisoning probe), 037 (documents with planted instructions)
Measure outcomes, not activityBusy is not useful; tokens rise when an agent loopsOracle's research on productivity beyond tokens
Autonomy is earned per action, on evidenceTrust that is not backed by measurements cannot be defended or withdrawn cleanlyNot on its own: every protocol produces the kind of evidence the Citadel trust model asks for

Two of these deserve a sentence more.

The system of record wins is the pattern most tempting to break, because copying data into an agent's knowledge or memory is so convenient. But an agent that answers from a copy is answering from the past. Two experiments test it from different sides: one asks whether record questions should bypass retrieval altogether, the other whether memory gives way when the record disagrees.

Hand-offs are where integrations break comes from how the Guild's missions are shaped. Athena receives and routes the work, specialists act, Sentinel holds the boundaries and Oracle measures. Each of them can pass its own evaluation while the work falls between them. Experiment 041 exists to find out how often that happens, and what it takes to catch it.

What writing the protocols made clear

Even without results, writing four protocols side by side showed things they all share. These are observations about the protocols themselves; anyone can check them against the pages.

Four scrolls on a stone table, each with a ruler, a wooden stool and a sealed lock, joined by gold threads, a cyan figure tracing one.
  • Every one needs "correct" defined before anything is measured. The expected end state of a mission, the right answer to a memory probe, the answer a document's owner approved, the business's own definition of done: none of the four can be measured until someone has written down what "correct" means.
  • Every one needs a baseline that is not the clever option. No memory at all. A single simple retriever. Each agent scored on its own. The work done without the agent. A new design has to beat the plain one on something that matters, or it does not ship.
  • Every one has a must-pass condition that no average can rescue. A leaked customer detail, an obeyed instruction hidden in an old message, a restricted document in an answer. One failure fails the design, whatever its other scores.
  • None can be settled by a public benchmark alone. Public benchmarks shaped the tests — LongMemEval, τ-bench, RAGAS — but each protocol needs scenarios shaped like real operational work, and two of them need a business's own records and owners. That is why the Forge's results take longer than a demo.

What would change our minds

Each pattern above could turn out to be wrong, and the protocols say how we would know. If per-agent scorecards catch hand-off failures after all, evaluation gets simpler. If tokens track outcomes well, they are a cheap proxy and Oracle's research will say so. If unguarded memory proves as safe as guarded memory, the guards are not earning their cost. If one simple retriever matches the hybrid, operations get cheaper.

A wizard and a cyan hooded figure on a battlement at dawn watch a gold weathervane swing to a new direction, a toppled flag at their feet.

Every one of those outcomes would make the Guild's work simpler or cheaper. We would rather know than assume.

Where to go next

Start with the experiment closest to your own question in the table above. For the thinking behind them, read Merlin's dispatch on testing persistent memory, Athena's on why intake quality matters and Oracle's five measurements. The Evaluation Lab shows where all of this ends up: the scorecard an agent must pass before it is trusted with real work.
