Talk by Andrew Dumit (Watershed Technology Inc.) on building a domain-specific coding agent for sustainability data tasks. Because the domain involves judgement calls and implicit knowledge, models can reach right answers with wrong reasoning. Rather than relying on smarter models, Watershed built a coding harness applying general coding-agent best practices (linting, routing failures back, sub-tasking), constraining commits through a deterministic, typed SDK with owned final execution. They report improving accuracy from 43% to 92%, with remaining differences from reference answers still valid, traceable, and replayable. The talk covers design decisions about what to constrain versus leave free. # Channel Identity Observations: "Respect The Process" — Andrew Dumit, Watershed Technology Inc. ## Video-Level Identity This is a **conference-style technical talk** delivered by a named practitioner, Andrew Dumit, who introduces himself as working on **AI engineering at Watershed**, which he self-describes as "the sustainability air platform" (transcript likely garbles "AI platform"; he closes with "Watershed, the sustainability AI platform"). > "Hi everyone. My name is Andrew Dumont and I work on AI engineering at Watershed, the sustainability air platform." - **Format**: Single-speaker presentation with slides, code examples, and eval metrics — consistent with a developer/AI-engineering conference or meetup context. - **Duration signals**: A complete, structured talk with opening, body, and closing ("That's it for me... Thank you again for your time and attention."). ## Explicit Self-Description - **Speaker role**: AI engineer at a company building "AI for building product carbon footprints and in turn measuring the emissions associated with all the things that a company buys and sells." - **Company domain claim**: Sustainability/carbon accounting is presented as a vertical "with a ton of expert judgment calls spread throughout it." - **Talk scope claim**: "In this talk, I'll go deep on one of the tasks within sustainability that we spend quite a bit of time working on and share learnings from our work deploying coding agents on that task." ## Intended Audience (Observable Evidence) - **AI/agent engineering practitioners**: References assume familiarity with agents, e.g. "If you're watching this, you've probably had that experience with cloud code where it's gone a bit haywire" (likely "Claude Code"), React agents, evals, and prompt engineering. - **Builders of agentic systems in expert-judgment domains**: The closing is a direct how-to for harness designers: "the harness should give the agent well scoped primitives... maintain full control of the final execution... produce outputs that are easy to validate even for non-coders." ## Claimed Scope and Demonstrated Expertise - **Claimed scope**: Deploying coding agents for a specific production task — helping users edit complex supply-chain emissions graphs ("thousands of nodes, each with rich metadata"). - **Demonstrated technical depth** (observable in transcript, not just claimed): - Architecture details: a **TypeScript typed SDK** as "the only door" for graph edits, linting, conflict detection, and a **deterministic "run executor"** that validates outputs. - Quantified results: "we've been able to improve our outcomes from about 43% to 92% on our set of internal evals." - Cited external research: a 2020 wine-bottle study ("answers that varied by up to 50%") and a "2026" paper ("the Open Proof Corpus" and "Beyond Correctness") — note the year is as-stated in the transcript and may be a transcription artifact. ## Presentation Style (Observable) - **Practitioner case-study framing**: problem → failed first attempt → coding-agent swap → new failure modes → harness solution → measurable improvement. - **Candid about failures**: explicitly describes the agent hallucinating schema, "gaslight[ing] users sometimes saying it had made edits when it hadn't," and "unconstrained code is quite scary." - **Non-coder empathy**: repeatedly emphasizes end users "are not software engineers," grounding the design in user reviewability rather than pure engineering concerns. ## Notes on Source Reliability - Transcript appears machine-generated: garbles the speaker's name ("Dumont"/"Dumit"), "sustainability air platform," and "cloud code." Identity observations above rely on the title spelling ("Andrew Dumit") where the transcript is inconsistent. - No curated metadata was supplied, so all observations rest on title and transcript alone. # Delivery Observations: Andrew Dumit — "Respect The Process" ## Tone & Register - **Conversational-engineering tone**: The talk blends a conference presentation structure with casual spoken asides, e.g. > "and we thought these will work great. So, naturally, we swapped them in." - **Self-aware, understated humor**: > "we quickly learned that unconstrained code is quite scary." and > "you've probably had that experience with cloud code where it's gone a bit haywire." - **Direct audience address**: opens and closes with explicit greetings: > "Hi everyone. My name is Andrew Dumont" ... > "Thank you again for your time and attention." ## Structural & Teaching Habits - **Numbered enumeration of problems and solutions**, used at least three times: - Three coding-agent benefits: > "swapping in a coding agent gave us like three really important outcomes" - Three problems: creative rule-breaking, false reports, hard review — later explicitly revisited: > "to return to those three problems that uh we started with" - Three harness recommendations at the end: > "First, it should give the agent well scoped primitives... the harness should also maintain full control of the final execution... And finally, you should use that deterministic final outcome..." - **Concrete domain framing before technical detail**: opens with sustainability-specific questions: > "what are the emissions attributable to one bottle of wine" - **"Zooming in" pattern — general to specific**: > "let's zoom into a specific task that we'll be talking about for the remainder of the talk." - **Problem → solution → revisit structure**: problems are set up early and explicitly resolved in the final third: > "So, to return to those three problems..." - **Concrete numeric examples**: > "six experts were given the exact same data" / > "varied by up to 50%" / > "from about 43% to 92%" / > "749 edit actions... reduced the overall emissions by 45.6%." ## Recurring Phrases & Vocabulary - **"The process" as a refrain**, matching the title: > "you have to verify the process in addition to the answer", > "validating the process", > "faithful to the process", > "you must respect the process, too." - **Repetition of "exact same"** for emphasis in the wine study: > "the exact same data on the exact same bottle of wine... access to the exact same things." - **Recurring vocabulary cluster**: "agent," "graph(s)," "SDK," "deterministic execution," "evals," "tool calls," "context" — the technical lexicon of the talk. - **Repeated contrastive formula "not X, but Y" / "X not Y"**: > "constraining the effects, not the expression"; > "The code is kind of just the means to an end." ## Communication Patterns - **Hedged, filled speech throughout**: frequent "um," "uh," "kind of," "like" — e.g. > "it's kind of adds constraints", > "kind of agentic data science workflows." This suggests live, minimally-scripted delivery (uncertain — transcript alone can't confirm). - **Immediate self-correction and restatement**: > "it said, 'I'm done. Everything's Everything's working.'"; > "and why do do I doing so has required" (transcription-level disfluency). - **Citing external evidence**: references a 2020 wine study, a "recent paper uh in from 2026, the Open Proof Corpus," and "Beyond Correctness" authors, plus "impossible bench" — supporting claims with named sources (delivery habit of evidence citation). - **Signposting transitions**: > "So, let's go a little deeper on...", > "So, to bring it all together...", > "Just for a brief example on the right here." - **Empathetic framing of user experience**: > "manual review of code is not something that... is in our users' wheelhouse." ## Uncertainty Notes - Timestamps and pacing cannot be observed from the transcript; disfluency density suggests spontaneous delivery but may partly reflect transcription artifacts. - Repetition of "kind of" is clearly frequent; distinguishing habit from filler is not fully determinable. # Respect The Process — Andrew Dumit, Watershed Technology Inc. ## Speaker - **Andrew Dumit**, AI engineering at **Watershed**, a sustainability AI platform. Works on AI for **building product carbon footprints** and measuring emissions associated with what companies buy and sell. ## Core Thesis - Sustainability involves many **expert judgment calls**; many wrong ways to get a right answer and many defensible answers experts disagree on. - Therefore **the process must be verified in addition to the answer**: "the answer is really only justified in so far as the process that produced that answer is correct." ## Evidence Cited - A **2020 study**: six experts with identical data on the same bottle of wine produced answers varying by up to **50%**. All judgments were "correct in a sense," so validating only the answer is insufficient for a system mimicking experts. - A "recent paper" (speaker says **2026**), the **Open Proof Corpus**: gap between correct final answer and correct proof in math, "potentially closing." - Agents **reward hacking** on "Erdos problems," Impossible Bench; authors of "Beyond Correctness" conclude significant risk for critical applications. (Speaker notes the problem is worse in sustainability where answers can't be fully verified.) ## Task: Editing Complex Supply-Chain Graphs - Graphs represent a product's supply chain (e.g., **dark wash jeans**), with thousands of nodes and rich metadata. ### Attempt 1: React agent with specialized tools (~a year earlier) - Worked "decently well" on one graph but lacked **consistency**, consumed heavy context. - Broke when scaled to a few/many graphs: inconsistent approaches, forgotten graphs, exploration bottleneck, hallucinated schema, retries, errors. ### Attempt 2: Coding agents - Three gains: ability to **delight users** (clever solutions, on-the-fly visualizations, related questions); **efficient exploration/editing** (loops over graphs, scripts summarizing nodes); **flexibility beyond design**, with new use cases still emerging. - Three problems: 1. **Unconstrained code is scary** — e.g., wrote Python (finding it on the VM) when instructed to use TypeScript; directly edited graph artifacts without leaving lineage. 2. **False reports** — agent "gaslit" users, claiming edits were made when they weren't. 3. **Hard review** — users aren't engineers; when "right for the wrong reasons," checking requires reading code. ## Solution: "Constrain the effects, not the expression" - Agent freely writes code, but critical graph-editing code must pass through a **typed SDK** filter (lint/check), and Watershed **owns the final deterministic execution**, producing typed, committed edits. - Result: process is **valid, traceable, replayable**; failures rejected and sent back to the agent. ### Typed SDK as "the only door" - TypeScript SDK with edit primitives; enforces editable vs. derived fields; prevents self-conflicts; requires a top-level edit function; provides `find nodes`, assertions for fail-early, and mutators like `set rate` / `edit node`. - Teaching the agent the SDK mirrors teaching an agent a codebase; agent has access to SDK docs/code. ### Deterministic execution (the real guarantee) - Run-executor script on agent completion: 1. Lint agent code; fail early. 2. Detect conflicting edits. 3. Run the edited code. 4. Validate output artifacts. 5. Produce a **structured review artifact** readable without reading code (e.g., a report: 50 graphs, 2 functions, 749 edit actions, emissions reduced 45.6%). ## Resolution of the Three Problems - Creative problem-solving retained; invalid actions prevented by the SDK-only path. - False reports caught by deterministic execution and surfaced back. - Users never read code; verification built against structured artifacts for both user and AI. ## Continued Improvement ("hill climb") - Internal eval accuracy improved from **~43% to 92%** via: prompt/system-prompt rewrites, few-shot examples, better SDK/tool ergonomics, plan-and-execute task decomposition, and encoding/expert judgment elicitation. - Qualification retained: even when the agent errs or ground truth is one point on a range of expert judgments, **the process itself is still guaranteed and validated**. ## Recommendations for Harnesses 1. Give agents **well-scoped primitives** for the external system; allow/disallow specific actions. 2. **Maintain full control of final execution** — validate the agent did what it claimed. 3. Use deterministic outcomes to produce outputs **easy to validate for non-coders**; "the code is just the means to an end." 4. Standard context and prompt engineering remain critical. # Speaker Attribution & Provenance Record ## Video Metadata - **Title:** Respect The Process - Andrew Dumit, Watershed Technology Inc. - **Video ID:** `01a15ca8-d3cb-70c3-b614-61db2302b7fe` - **Format:** Single-speaker conference/presentation talk ## Speakers & Roles | Speaker | Role | Evidence | |---|---|---| | **Andrew Dumit** (transcript also renders as "Andrew Dumont" once) | **Creator / presenter**, AI engineering at Watershed | Self-introduction: *“My name is Andrew Dumont and I work on AI engineering at Watershed, the sustainability air platform”*; closing: *“I'm Andrew Dumit at Watershed”* | **No other speakers** appear — no guest, narrator, panel, or audience voices are present in the transcript. ## Promotional Segments - **Mild organizational self-identification** at open and close (speaker's name and Watershed affiliation).

Hi everyone. My name is Andrew Dumont and I work on AI engineering at Watershed, the sustainability air platform. At Watershed, I work on AI for building product carbon footprints and in turn measuring the emissions associated with all the things that a company buys and sells. Sustainability, the vertical that Watershed is in, is one with a ton of expert judgment calls spread throughout it and this has made building and deploying agents both exciting and challenging. In this talk, I'll go deep on one of the tasks within sustainability that we spend quite a bit of time working on and share learnings from our work deploying coding agents on that task and why do do I doing so has required that we respect the process. So just to give a bit of context on sustainability as a vertical, we need to answer questions like what are the emissions attributable to one bottle of wine or which method should be used to allocate the emissions to various co-products when there are multiple sellable co-products that come from the same industrial process. In these cases, there are many ways to get the right answer the wrong way and there are also many right answers that experts will disagree on. And so, you have to verify the process in addition to the answer because the answer is really only justified in so far as it the process that produced that answer is correct. One example of this comes from a study in 2020 where six experts were given the exact same data on the exact same bottle of wine and despite having all access to the exact same things, they came to answers that varied by up to 50%. Their expert judgment were all correct in a sense, but purely validating the answer here is not sufficient to know that the answer produced by a system trying to mimic those experts is itself correct. So with that context on sustainability broadly and what kind of things that we need to answer, let's zoom into a specific task that we'll be talking about for the remainder of the talk. That task is to help users edit complex graphs. Each of these graphs represents the supply chain of a single product. For example, on the right here, you can see the graph represents dark wash jeans. Upstream of that is the assembly of that jeans from the denim thread, labels, uh and zipper, along with the energy, transportation, and packaging that's required to move uh move that through the supply chain, and create uh and run those industrial processes. Each graph here represents the entire flow of all of those things moving through the supply chain, and is comprised of thousands of nodes, each with rich metadata describing the materials and processing at each step. And so, when we first tried to solve this problem a little over a year ago, it worked decently well on one graph. It did have some problems, but we gave our React agent highly specified tools for exploring and interacting with the graph via function calls. And even while it worked, a few problems were already apparent. Um it lacked consistency where it could struggle to explore sufficiently, and those tool calls on a single graph took a lot of context as it read deeply across these nodes with lots of metadata. But then, when we tried to scale it up to many graphs, or frankly even just a few graphs, it absolutely broke. The lack of consistency was greatly magnified with the agent taking one approach in one graph, a different approach in a second graph, and completely forgetting about the third graph, or even to handle it at all. And exploration itself also became a huge bottleneck because it took many tool calls to explore and operate across these graphs at scale. And it also worsened the context problem because these tool calls really gobbled up context both on the edit side where it actually needed to like make some changes, and on the exploration side where it needed to figure out what changes to make. And worse, the agent then really started to hallucinate different parts of the schema as those contexts got eaten, and despite those specialized tools, this led to retries and ultimately errors. In data terms, the task now comprised tens or hundreds of graphs, and tens to hundreds of thousands of nodes that the agent had to operate over. So, time passed, and coding agents got way better, and we thought these will work great. So, naturally, we swapped them in. And swapping in a coding agent gave us like three really important outcomes that we were missing before. First, it gave the agent the ability to delight users. The agent could start to find clever ways to solve these under-specified and kind of not fully formed problems. It could also create fancy visualizations on the fly by writing code to do that. And it could even answer related questions because it had kind of the full power of the coding agent in this environment. And what from our end we saw the agent could explore and now edit way more efficiently than before. It could write loops over graphs and nodes. It could write scripts to unpack and summarize the node content underneath it all. Basically, following the same pattern of data exploration that goes on in kind of agentic data science workflows. And beyond that, it also gave it the flexibility and power to do stuff outside what we even designed it for, which was really exciting. And we're to this day consistently finding entirely new use cases via new questions users ask and new things that they want to try with this agent. We were really excited. We put it out into the world. We started to write a bunch of evals for it. And we quickly learned that unconstrained code is quite scary. If you're watching this, you've probably had that experience with cloud code where it's gone a bit haywire towards achieving whatever goal you set it out to do. It reached for something you didn't think it could or should reach for or even had access or found a way to access something you didn't think it could. Um for us, this looks like the agent will find creative ways to pretty much solve any problem. In our case, we saw it write Python when we expected TypeScript and and instructed it to write TypeScript because it found Python on the virtual machine that we had given it. Or it would directly edit these graph artifacts underlying the data without leaving any lineage behind by just like directly modifying um parameters or data rather than actually like writing code to effectively do that. Second, the agent actually started to gaslight users sometimes saying it had made edits when it hadn't. Um it would write code that did that it thought was going to do make like have the effect that it wanted to. And then it said, "I'm done. Everything's Everything's working. It's exactly what you said." And the edits were not actually made. And so it it kind of lied to users or at least let them to believe that the edits were done as they expected it to be done. And then lastly, once the agent had completed its task, it was now much harder to review its work. Um manual review of code is not something that are is in our users' wheelhouse. They are not software engineers or may or may not have had experience with code before. And when the agent is right for the wrong reasons, which happens uh or can happen frequently in our in sustainability broadly, it's really hard to check its work without going and reading that code directly. And so this process is not the answer. Story is really not new. Um a recent paper uh in from 2026, the Open Proof Corpus, showed that there can be quite a big gap between the correct final answer and and the correct proof. Though that is, you know, potentially closing. But And this is in math where there is like a fully verifiable answer. And so this We view this problem as even worse where you can't fully verify the answer. And this has been found in the agents what reward hack um even as something as complex as the Erdos problems, um you're going to get many, many pages of of errors in your proof which have which lead nowhere um to impossible bench to um other kind of areas in math where this can where they can The authors of this paper, Beyond Correctness, conclude that this can pose significant risk for critical applications. Now, all this is not to say that we shouldn't use coding agents. We don't want to constrain how the agent reasons. We get so many benefits from these powerful models, but we also can't perfectly verify the answer in our case. So we don't even know when the final answer is definitely correct. Uh because these expert judgment calls are ever present our space. So, the main lever left is validating the process and making sure that we are following it in a way we expect. And to do that, we frame it as constraining the effects, not the expression. So, our task begins with a user request. And from this, the agent can then go off and freely write code to execute on that user request. However, we require that all the critical code, really the stuff that edits the graph, goes through a filter of this typed SDK that we've put together where we can lint and check for errors. And then we own the final execution step to guarantee that we create these typed objects that we can commit as the actual edits to the graph. And these are then faithful to the process. And all of this together means that the entire process is valid, traceable, and replayable. And if it's not, we can reject and retry and send it back to the agent to let it know that something has gone awry. So, let's go a little deeper on the typed SDK and the deterministic execution. So, first, our SDK is the only door. What we give to the agent in our case is a TypeScript SDK with all the edit primitives the agent needs to make changes to graphs, as well as explore and interact with the kind of graph objects. This for us enforces which fields are editable versus which are derived from other fields, so the agent can't create conflicts with itself where it edits just the target thing that it cares about, but not the thing that creates that target thing. And it also guarantees that it objects that we expect it to so that we can actually like make use of the outputs of this in a deterministic way. Now, of course, this does require teaching the agent how to actually make use of this SDK, but this is the same kind of pattern that we see with teaching an agent to like write code in your code base where you tell it how it works. You can, you know, do the prompt and all of that kind of stuff. The agent also has full access to the docs and the code underlying the SDK if it really needs to go and read that as well. Just for a brief example on the right here, you can see an example with a few pieces of the SDK on display. We import um from our API. We The agent has to then define kind of a top-level edit function with a well-defined name. It then can use uh find nodes by exact name to find specific nodes that it's looking for in the graph. It can write assertions that we give it to make sure that um its code fails early um as well. And then it can use uh specific mutator functions like set rate and edit node to actually interact with the graph in a way that will produce those kind of typed objects that we care about. So, that's the SDK, but the actual guarantee here is when we own the deterministic execution. So, even with the typed SDK as our entry point, that really only guides the agent towards the desired end state. And the real guarantee comes from the final script that we orchestrate on agent completion. This run executor script um it is called when the agent has kind of completed running, and we think that we're in a like almost completed state or a ready to be completed state. And what that script does is it starts by linting the agent code, where we can immediately send it back to the agent if something is wrong. Better to kind of fail early rather than fail later. We can also detect conflicts. This is where sometimes the agent in one part of the code edited something in another part edited the same thing or something that depended on the first one and didn't realize that that happened. Because we have these guarantees, by giving the agent this well-defined structure, we can detect those conflicts for it so that we can send it back to the agent. We then run the agent edited code, and that means that we can then validate the output artifacts. Of course, if the code itself fails to run, we can send that back to the agent, too. And then finally, once we have the validated output artifacts, we can create a well-structured review artifact that makes it easy to review what the agent did without having to actually ever go read the underlying code that produced it. To give you a flavor of what that looks like, here's a little snippet from an emissions report where the graph edit function impact analysis ran on 50 graphs. Um there were two functions that it applied that produced 749 edit actions, and it ultimately in this case reduced the overall emissions by 45.6% and we can even go to go to see there are two code there are two edits here. Um one kind of did a big chunk and the other one made a very small change. Maybe you'd go look at what this actually did, and then you can even go at a graph level and say, "Okay, for this graph, like what was the option one and which nodes did it edit within that graph to get a sense of um what actually happened under the hood?" So, you can see all of this without actually having to go read the low-level code. So, to return to those three problems that uh we started with, now that we have these kind of two broad concepts that are part of the harness, um when the agent will find creative ways to solve every problem, this is now a great thing, but we've limited it a little bit. These invalid actions that the agent will take on its route to solve whatever problem we presented are actually prevented with the type dust SDK as the only way to properly edit the graph, and then we can guarantee that the graph was only edited through the SDK by owning the deterministic execution and the validation of that written code. The second problem about the agent saying that it made an edit when actually that the edit didn't go through in the way that it or the user expected, these false reports are caught via that deterministic execution so that we can surface those back to the agent um to make sure that it's doing what it claimed. And finally, our users never have to look at the code because the deterministic execution system produces artifacts in an expected form, and we can build verification against those to catch both the kind of good outcomes and the errors that are now surfaced clearly to both the user um and the AI. So, even when it hasn't maybe gotten exactly the right answer or the one that the user expected, it's easy to follow its logic and kind of get to that um and loop back on itself. Now, the harness is all well and good as it's kind of adds constraints, but I also want to emphasize that even with those great guarantees, you still need to hill climb to get better at the task itself. Since we started tracking how well the agent did at these complex edits, where each task here um in our eval set is a collection of graphs and a goal, um we've been able to improve our outcomes from about 43% to 92% on our set of internal evals. And to achieve that, all the typical approaches were still effective. We did a ton of prompt improvements, like rewriting the system prompt and all the kind of skills that the agent had access to. We've added few shot examples to both teach and coach the agent how to make use of the SDK and work with these different classes of tasks that we expect. We also had to make the tools, the SDK itself, and the tools the agent had access to better fit for use by improving their kind of ergonomics and how obvious they were for the agent to use. We also broke the task down through doing this, breaking up the um overall problem to a plan and execute kind of standard loop, as well as teaching the agent some of that expert judgment that is endemic in our space, making that easier for the agent to operate on it and to elicit that expert judgment from the user. But the important thing here is even though we've kind of improved the accuracy here, which is amazing, and it's great that we'll now kind of get better at that first time a user goes through the full workflow in the task, um even when the agent errors, or even our ground truth is, you know, one of those points on the possible range of expert judgments, we can still guarantee and validate the um process itself. So, to bring it all together in a domain full of expert judgments, you must respect the process, too. And for that, you really need guarantees about the process. We all know coding agents are necessary for complex tasks, and they will continue to be necessary and extremely useful. But those power that power comes with many risks that are like good to go and clear eyed about. For tasks with complex data and judgment calls, we now think that the harness should do a few important things. First, it should give the agent well scoped primitives to interact with the kind of external system that it's actually supposed to work with. Um free freely operating code can, you know, lead to a lot of the things that we talked about earlier. And this really allows the builders of the system to allow and disallow specific things and exercise the full power of these coding agents while still trusting the process that they're working in. I think the harness should also maintain full control of the final execution. These very smart agents may declare victory in an unexpected way from what you or your user really want them to declare. And so it's important to be able to constrain and validate that the agent has actually done what it said it's done. And finally, you should use that deterministic final outcome to produce outputs that are easy to validate even for non-coders. The code is kind of just the means to an end. And then of course, the kind of standard context and prompt engineering will of course remain critical to better scoping and defining that task and making it clear what the agent needs to do. That's it for me. Again, I'm Andrew Dumit at Watershed, the sustainability AI platform. Thank you again for your time and attention.
