We specify a pre-registered protocol for Did the introduction of the IEX-style speed bump on a mid-size US exchange reduce the rate of detectable latency-arbitrage round-trip patterns relative to matched control venues, in the 60 trading days surrounding the activation date? using NYSE Daily TAQ quote-level (WRDS); SEC Rule 605/606 public disclosures; MIAX/IEX historical press releases documenting activation dates.

We specify a pre-registered protocol for Did the discrete maker-taker fee inversion events documented on NYSE Arca produce a statistically significant change in intraday small-lot quoted-spread variance for affected symbols, relative to a matched control set on a non-Arca venue? using NYSE Daily TAQ (accessible through WRDS subscription; alternatively, IEX DEEP feed, public; Cboe Global Market Statistics public daily summaries).

We describe Spindrift, A streaming post-processing layer that collapses short-horizon token repetitions introduced by nondeterministic decoding paths.. Inference stacks that batch requests or run across multi-GPU splits are not bit-exact across replicas.

We describe Threader, A retrieval index for coding agents that returns the caller/callee neighbourhood of a symbol, not just the file containing it.. Retrieval-augmented coding agents typically chunk code by file or by fixed token windows.

We describe Stagehand, A minimal pattern and library that splits every irreversible agent action into a dry-run plan and a signed commit step.. Agents performing irreversible actions (file deletion, financial transactions, external emails, database migrations) currently interleave plan and commit in one step.

We describe Veil, A small logging shim that strips secrets from tool-call traces at the moment of serialization, not at post-processing.. Agent frameworks routinely serialize tool inputs and outputs into trace files for debugging and replay.

We specify a pre-registered protocol for When system-prompt layers contain direct contradictions (e.g.

We specify a pre-registered protocol for When a benign tool returns a result containing an adversarial instruction, how often do four public 2025-era agent frameworks (configured out-of-the-box) obey the injected instruction versus ignore it? using AgentDojo benchmark (Debenedetti et al.

We specify a pre-registered protocol for Given a frozen set of PDDL domains and a frozen model revision, do three public planner-LLM implementations (LLM+P-style translation, chain-of-thought direct planning, and ReAct-with-validator) produce reported success rates within their own published confidence intervals on the same problem set? using IPC-2023 classical planning domains (public), Blocksworld and Logistics from the PDDL-generators repository, and the PlanBench problem set (Valmeekam et al.

We specify a pre-registered protocol for Do three commonly cited LLM-as-judge protocols (pairwise with position-swap, single-answer grading with rubric, and reference-anchored scoring) produce statistically different Elo/Bradley-Terry rankings when applied to the same fixed pool of open-weights models and the same prompt set? using MT-Bench prompts (Zheng et al.

We specify a pre-registered protocol for For reasoning tasks where published results report accuracy under 'majority-vote over 5 samples at temperature T', how sensitive are the reported accuracies to the choice of N (number of samples), temperature T, and aggregation rule (strict majority vs plurality vs weighted)? using GSM8K and MATH (Hendrycks 2021) test sets at pinned versions.

We specify a pre-registered protocol for How many problems in HumanEval and MBPP are near-duplicates of each other at a pre-specified fuzzy-match threshold on prompt, docstring, and test-case text, and does this cross-contamination bias any comparison between HumanEval-tuned and MBPP-tuned models? using the two benchmark sets in full, plus their expanded variants (HumanEval+, MBPP+) from Liu 2023.

We specify a pre-registered protocol for For three widely-used 2025-era open instruction-tuning datasets, what fraction of their examples are near-duplicates (at a pre-specified similarity threshold) of items in five widely-used evaluation suites (MMLU, GSM8K, HumanEval, MBPP, TruthfulQA)? using the three instruction datasets and five evaluation suites (all publicly available on HuggingFace) at pinned revision hashes.

We specify a pre-registered protocol for Across 12 recent papers that report HumanEval Pass@1 for a specific model, how consistent are the evaluation protocols (prompt style, temperature, post-processing, test harness version), and when all papers are re-run under a single common protocol, how do Pass@1 numbers change? using HumanEval (Chen et al.

We specify a pre-registered protocol for When the same agent framework is run on SWE-Bench Verified with the same base model weights but different inference stacks, how much does the reported Pass@1 vary, and is the variation concentrated in specific repositories or failure classes? using SWE-Bench Verified (public release at pre-registration date), patch-level evaluation harness.

We specify a pre-registered protocol for For a set of Model Context Protocol servers implementing the same tools with the same declared schemas, do three client SDKs discover and enumerate them identically, or do edge cases in tool-schema rendering, transport negotiation, and auth handling differ? using a pre-registered set of 10 reference MCP servers (stdio, SSE, and HTTP transports) implementing tools spanning simple params, nested schemas, optional/required interactions, and auth-gated endpoints.

We specify a pre-registered protocol for Given the same rendered web page and the same user instruction, what fraction of tasks result in different click targets across four browser-using agents, and do divergences correlate with DOM structure features (shadow DOM, iframes, overlaid elements)? using a pre-registered suite of 50 rendered pages including static reproductions (archived) of real web pages spanning e-commerce, forms, docs, SPAs, and pages with shadow DOM / iframes.

We specify a pre-registered protocol for Given a set of parallel workflow definitions implemented in both LangGraph and LlamaIndex, can intermediate workflow state be transferred between the two frameworks at checkpoint boundaries, and if not, what serialization features differ? using pre-registered parallel implementations of 15 workflows each in both frameworks covering RAG, tool-call chains, and branching decisions.

We specify a pre-registered protocol for When AutoGen and CrewAI agents are composed into a shared workflow with a standard task set, what concrete interoperability failures occur (tool-schema mismatch, message-format incompatibility, state serialization), and can any be solved with a thin adapter layer? using a pre-registered suite of 20 composed workflows spanning code-generation, data-retrieval, and planning, each requiring agents from both frameworks to exchange artifacts.

We specify a pre-registered protocol for For five recent papers that claim effective prompt-injection defences, can the claims be reproduced at the originally reported success rates when evaluated against a shared, pre-registered attack corpus? using pre-registered attack corpus: 300 prompt-injection attempts drawn from public red-team collections (e.
