## Project Overview You will author a single terminal-based task and evaluate whether an AI coding agent can solve it end-to-end. Your goal is to design a task that is genuinely hard for frontier AI agents to solve, strictly verifiable, and resistant to shortcuts. The agent receives your instructions as its prompt, operates inside a Docker container with only shell tools, and writes its output to `/app/`. A deterministic `pytest` verifier then grades the run. > **CRITICAL WARNING:** You must write the prompt (`[login to view URL]`) yourself, in your own voice. Do not use AI to write or edit your instructions. The rubric heavily penalizes AI-generated instructions. You may use AI for everything else (coding, testing, etc.). Please don't send me automatic offers using Ai either. ## Deliverables You will produce a single task directory containing four core files that define what the agent does and how it is graded: * **`[login to view URL]`**: The prompt the agent reads at the start of the task. * **`[login to view URL]`**: The task's metadata and resource configuration. * **`solution/[login to view URL]`**: A reference solution proving the task is solvable and the tests accept a correct answer. * **`tests/[login to view URL]`**: The pytest assertions that grade the agent's output. ## Workflow and Phases This is a procedural workflow. You will move through these phases in strict order to minimize wasted effort. 1. **Proposal Phase:** Approval required before coding. You will draft `[login to view URL]` and submit it for a proposal check. We will iterate on the instruction until the reviewer returns an Accept status. This catches bad task ideas before you invest time in building the tests and solutions. 2. **Implementation Phase:** Building and refining. You will complete the remaining files and submit them for validation, quality checks, and a cheat trial. Findings from each step will route back to you for edits. You will iterate until validation stays green, the quality review is clean, difficulty lands in range, and the cheat trial finds nothing. > **Note on Difficulty:** Because this project targets problems that are hard for frontier models, do not expect an AI (like Opus or Claude Code) to produce the oracle solution for you. If Claude Code can write a working `[login to view URL]` from your instructions without substantial back-and-forth, the task is too easy and the proposal must be revisited. ## Task Categories If a task could credibly land in two categories, pick the one that describes what the agent actually has to do to solve it. | Category | Scope | | --- | --- | | **`software_engineering`** | Writing code, fixing bugs, refactoring, migrations, build and dependency work. | | **`system_administration`** | Shell, processes, filesystems, packaging, configuration, operational tooling. | | **`security`** | Vulnerability analysis, exploit development, hardening, forensics, cryptography. | | **`data_science`** | Data wrangling, statistical analysis, reporting, visualization. | | **`machine_learning`** | Training, inference, evaluation, model fine-tuning, pipeline work. | | **`scientific_computing`** | Numerical methods, simulation, computational workflows for natural sciences. | | **`other`** | Anything that genuinely doesn't fit the above. Use sparingly. | **Current Hardware Policy:** We are **NOT** accepting GPU-dependent tasks right now. Please keep `gpus = 0` in `[login to view URL]`. CPU-only machine learning, data science, or scientific computing tasks are completely welcome. ## What Makes a Good Task? A high-quality task is something a person would be paid to do on a computer—real, economically valuable work. It must be specified by a clear instruction and a robust verifier (a solution passes if and only if it actually completes the work), and it must be robust across time and hardware. ### Good Levers for Difficulty * **Longer horizon:** Multi-step work where an agent must plan, execute, and verify across many sub-goals. * **Richer environment:** Many microservices, large filesystems, multiple databases, or real applications the agent must navigate. * **Specialized knowledge:** Domain reasoning a generalist agent cannot bluff its way through. Lean into your strongest domain! ### What to Avoid * **Arbitrary complexity:** Stacking irrelevant steps or baroque constraints just to make the task long. * **Hidden requirements:** Failures should come from the work being genuinely hard, not from the agent guessing your intent incorrectly. * **Misleading statements:** The words must match the code and tests. Do not describe a bug that isn't actually present in the seed environment. ### Anti-Examples: Bivalent Phrasing Do not use phrasing with two or more reasonable readings if the verifier only accepts one. Agents should fail on the work, not on guessing your intended reading. **Example 1: Rendered Output vs. Raw Source** * *Bad Phrasing:* "Every eligible article should contain exactly one navigation block." (Is this counting what the browser renders, or the raw HTML including commented-out code?) * *Good Phrasing:* "The marker text for the current navigation block must appear exactly once in the raw HTML of every eligible article. Commented-out copies count toward this total and must be removed." **Example 2: Describing Input vs. Enforcing Validation** * *Bad Phrasing:* "Polygon rings must have at least four coordinates and a non-zero area." (Is the spec promising the input will look like this, or demanding the CLI actively check for it?) * *Good Phrasing:* "The CLI must validate every polygon and exit with a non-zero status if any has fewer than four coordinates or zero area." ## Self-Check and Quality Requirements Every task must clear these bars before the quality reviewer will accept it: * **Instruction ↔ Verifier Alignment:** Your `[login to view URL]` must pass on your `[login to view URL]` reference solution and fail on a no-op solution. Every tested behavior must be explicitly called out in the instruction. * **Reproducibility:** The Docker image must build deterministically from pinned dependencies. Reruns must produce the same verdict. * **Cheat-Robustness:** The task must survive `scripts/[login to view URL]`. Adversarial prompts should not pass the tests without the agent actually doing the work (e.g., a test looking for a file can be bypassed by simply using the `touch` command). * **Calibration Honesty:** Your `expert_time_estimate_hours` should reflect the real work required. ### Final Verification Before submitting, re-read every *must* or *should* clause in `[login to view URL]`. Could a careful reader land on a different acceptable answer? If yes, commit to one reading or accept both. If you make a good-faith effort and the task remains too easy, is blocked by infrastructure, or no longer has a clear path, let us know. You will still be paid, and this does not reduce your chance of future work with us.

I understand the goal of this project: creating difficult terminal-based coding tasks to evaluate AI agents. I will design a clear task prompt, build a deterministic Docker environment, provide a reference solution, and write pytest tests that verify the agent truly completed the work. I have experience with Python, backend development, Docker, testing frameworks, APIs, and software engineering workflows. I can create realistic engineering challenges that are difficult for AI agents while remaining objectively verifiable. A few questions: Are there preferred programming languages or technology stacks? Should tasks start from an existing codebase or a blank environment? Are external packages and network access allowed? Do you have examples of previously accepted tasks? I look forward to contributing high-quality benchmark tasks for AI coding agents. Thank you.

The evaluation piece is where this gets tricky. I would design a task that looks solvable on the surface but requires real domain reasoning, not just pattern matching, so the model actually gets pushed. Python for the terminal runner, clean scoring logic, and a rubric that captures whether the agent understood the problem or just got lucky. I can start today and have the full task with eval script ready in 48 hours. Bid reflects the post as written. Final scope depends on the domain you have in mind. Want to jump on a quick call?

The hardest part is making the verifier impossible to cheat without the agent actually performing the work. I’ll write a short instruction that forces a multi-step shell flow, then add pytest checks for each intermediate file and exit code so shortcuts fail. A common mistake is to let the test only look for a final file, which lets the agent skip the real work by using touch. You can expect a task that passes only when the agent writes the correct script, runs commands in order, and produces output the verifier checks.

Dear Client, I read "Challenge frontier model with your genuine expertise in a field." carefully and understand you need hands-on Claude/Anthropic expertise to build or integrate an AI assistant that actually works reliably. My hands-on experience with Python, AI (Artificial Intelligence) HW/SW, System Administration aligns directly with what you need. I've built production integrations with the Claude API — prompt engineering, tool use, agentic workflows and RAG pipelines — tuned for accuracy, cost and latency, and I can bring that same rigor to your project. A few quick questions to get us started: 1. Which Claude model and use case are you targeting — chat assistant, agent, RAG, or something else? 2. Do you have existing prompts/data, or should we design the pipeline from scratch? 3. What's your expected usage volume, so we can plan for cost and rate limits? Thanks & Regards, Deepak

Hello, this is essentially benchmark engineering for coding agents, and the hard part is not writing pytest or shell scaffolding but designing a task that is difficult for the right reason. The real engineering risk is verifier leakage: if the assertions can be satisfied without the agent actually doing the work, the task looks rigorous but fails as an evaluation artifact. I’ve built several production AI systems where instruction-output alignment and deterministic validation mattered more than model demos. The closest relevant work is DocIntel AI, where I separated ingestion, extraction, storage, and answer verification so each layer had measurable behavior. Enterprise ProxyTool is also relevant because the architecture depended on clean control-plane versus data-plane boundaries, which is the same discipline good benchmark tasks need. I usually structure this kind of system by locking down one unambiguous success condition, then designing the environment so the agent has to traverse real intermediate steps to reach it. For this JD, I’d be focused on instruction/verifier alignment, no-op failure checks, and shortcut resistance inside the Docker and pytest constraints. These are the kinds of systems I design for long-term production use, where repeatability matters more than cleverness. If useful, I can outline a task design that is hard, deterministic, and resistant to superficial passes before implementation starts. Clifton
