Truncation handling, configurable model generation budgets, and recovery from missing tool arguments are implemented. The remaining sections describe problems and proposed work whose code has not yet been implemented. #### Truncation handling @@ -765,6 +765,157 @@ Missing required argument: path. Provide the file path and retry. The model can then supply the missing value in a later turn and continue within the remaining budget. Both display and execution must tolerate incomplete input; otherwise the crash is merely deferred to the next stage. The principle is to return model-correctable argument errors as tool results so the task can continue, rather than ending the entire task. Other tools should follow the same principle. +**Implementation on 2026-09-13: tool argument validation and error feedback.** The implementation commit is `27a9503`. Before preview or execution, `read`, `write`, `edit`, and `bash` share validation of required fields, the string/integer/boolean types declared in their schemas, and NUL characters in paths and commands. Unknown tool names also return errors. Arguments are not coerced: for example, `replace_all="false"` is not treated as true, and booleans cannot substitute for read line numbers. Extra fields permitted by the schema, empty file contents, and empty replacement text remain supported. + +Invalid calls do not reach tool implementations. Instead, they receive a `tool_result` matching the original call ID, with `is_error=True` and correction guidance. The preview indicates that the call did not execute. Other valid calls in the same reply still run in order, and recovery does not repeat successful tools. The next model reply retains the task, history, and remaining turns, without a separate retry budget. Unexpected programming exceptions inside tools still propagate, avoiding misclassification of every `KeyError` as a model input error. + +The agent also checks the argument JSON actually received in the response stream. The SDK parses partial JSON during streaming; a dictionary containing required fields does not justify executing a command if its closing brace is missing. When a stream finishes with `tool_use` but incomplete argument JSON, the call is rejected with a request for a complete object. Journals and ATIF retain the error, raw argument JSON, and SDK-parsed input. Non-object inputs are saved separately as `raw_input` while preserving existing object field constraints. Follow-up requests use sendable objects instead of replaying partial JSON. Existing `max_tokens` handling remains unchanged: all tools in a truncated reply are skipped and the run ends as `response_truncated`. Automatic continuation is not implemented here. + +**Automated validation and independent review.** All 276 core tests pass with locked dependencies. The same 276 tests also pass in a temporary environment pinned to the preceding experiment's reported Anthropic SDK 1.5.0, HTTPX 0.28.1, HTTPX2 2.12.0, and Pydantic 2.13.5. All 22 Harbor adapter tests pass. New coverage checks that invalid arguments have no side effects, incomplete JSON through the real SDK, corrected calls after error feedback, valid sibling calls, interactive/headless behavior, turn limits, and trajectory evidence. An independent reviewer inspected the complete change in a new Herdr split using the `review-agent` skill and reported **No findings**, additionally verifying mixed-call recovery through the real SDK and Harbor compatibility. + +The four actual failed response streams from circuit, QEMU, scheduler, and DNA were also replayed unchanged through SDK 1.5.0 offline. Each rejected the invalid call, returned an error, and then completed one valid call from a scripted follow-up reply before finishing normally. Tool execution was stubbed and there were no paid model calls. This demonstrates changed handling of identical failed inputs; it does not establish that those four real tasks pass. + +**Known boundary.** Recovery depends on the SDK delivering the response successfully. Some JSON syntax errors, including invalid escapes and trailing commas, raise inside the SDK before recovery can run; independent review confirmed that this limitation also exists on the main branch. Interrupted streams, algorithm errors, exhausted turns, and evaluation environment failures require separate handling. + +**Real-task rerun settings.** The reruns use the same reviewed wheel from `27a9503`, with `deepseek/deepseek-v4-flash-0731` through OpenRouter. Task refs and cached image digests for all original 20 tasks match the 09-06 baseline. Every reply explicitly uses `max_tokens=65536`, with 50 turns per task and at most two simultaneous trials; the project default remains 32768. Agent execution has 3600 seconds, finalization 120 seconds, and the Harbor outer allowance 3780 seconds. Verifiers retain their native task deadlines. Each task runs once per job with no automatic Harbor retries; additional reruns have separate job names and preserve earlier failures. + +In the first targeted5 group on 09-13, QEMU encountered APT 404 errors and DNA exceeded the 1080-second installation limit, both before any model call. PyTorch was paused by the user during installation, and circuit had not started. Subsequent groups increase only the **installation deadline** to 3600 seconds and retry system dependency installation at most three times on HTTP 404. The scheduler agent in that first group had already finished normally before the pause. After resumption, its unchanged artifacts in the preserved container passed all six official tests, yielding reward 1 with **no additional model calls**. This resumed verification is recorded separately from an uninterrupted Harbor trial. + +QEMU installation in the 09-14 targeted4 group still encountered intermittent 404 errors, so a separate retry uses the same 20 packages selected by the original APT index, downloaded from official URLs and checked against their SHA256 hashes and sizes. They enter the cache after `apt-get update`, before the original dependency installation. Preloading them earlier allowed the image's APT cleanup hook to remove them; correcting that order made installation succeed in the original image. Package versions and repositories remain the same. + +In the same targeted4 group, the PyTorch agent finished normally, but the official verifier exceeded its native 900-second deadline downloading Torch/CUDA dependencies, leaving the task unscored. A uv 0.9.5 cache was prepared for a separate retry and the subsequent full20 run, using the official script's unchanged requirements: `pytest==8.4.1`, `torch==2.7.1`, and `pytest-json-ctrf==0.3.5`. After relocation into the original image, all 31 packages installed offline and Torch imported successfully. Preparation ran no task tests. Only `pytorch-model-recovery` receives this cache; its official verification script and 900-second deadline stay unchanged. This changes cache conditions and must be distinguished from the tool argument fix's effect. + +The original 8192 baseline also used another source revision and agent deadlines. The preceding 65536 initial18 group passed five tasks; later supplements and compressor were separate attempts, while `regex-log` had only been rerun at 32768. Comparisons therefore keep the original 20 tasks and the matching 18-task subset separate, without combining different settings into one pass rate. Sampling, routing, cache, and backend state remain uncontrolled. Identical-response offline replays, observed recovery events in real runs, and final task scores are three distinct forms of evidence. + +**Targeted rerun results (2026-09-14).** The table preserves each historical argument failure and its observed rerun result. Installation failures, verifier timeouts, and supplements remain separate; these different conditions are not combined into one formal five-task score. + +| Task | Historical argument crash | Rerun result | Observed argument feedback | +| --- | --- | --- | --- | +| `dna-assembly` | `bash` missing `command`, with an unterminated JSON string | Reward **0**, **0/1** official tests; `max_turns_exhausted` after 50 replies and 3533.7 seconds of agent execution | None | +| `qemu-alpine-ssh` | `bash` missing `command`, with raw JSON `{` | Installation failures retained separately; cached retry reward **1**, **1/1** tests, normal completion after 48 replies | None | +| `llm-inference-batching-scheduler` | `write` missing `content`, with raw JSON `{` | Normal completion after 47 replies before the pause; resumed official verification reward **1**, **6/6** tests, no additional model calls | **One** incomplete `bash` JSON rejection, followed by another model call and a successful `bash` call | +| `pytorch-model-recovery` | The 8192 baseline omitted `edit.path` after timeout | First agent run completed normally but verifier downloads timed out; cached retry reward **1**, **5/5** tests, normal completion after eight replies | None in either run | +| `circuit-fibsqrt` | `bash` missing `command`, with raw JSON `{}` | Reached the 3600-second execution deadline after 49 replies; stopped artifacts passed **3/3** tests with reward **1**; **not a normally completed pass** | None | + +The experimental supervisor interrupted circuit, which ended with `KeyboardInterrupt` and exit 130; Harbor recorded `NonZeroAgentExitCodeError`. Finalization retained a native trajectory without a forced kill, and verification began only after the agent stopped. Both the passing artifact and the exhausted execution budget must therefore remain visible; reward 1 alone does not establish normal completion. + +Scheduler is the only real run in this group that directly demonstrates argument error feedback followed by continued execution and passing verification. Its new error concerns `bash` JSON, rather than the historical `write.content` failure. The other newly sampled attempts produced no argument validation errors, so their passes cannot independently be attributed to this feature. The preceding offline replays provide identical-input evidence for the four historical failed responses. + +Including scheduler, the first PyTorch verifier timeout, and both cached supplements, the group retains **six native ATIF files**. All validate against Harbor, match their full Journal projections, and contain no truncated Journal strings. These six runs account for 222 model replies, 12,183,309 input tokens including 10,021,376 cached tokens, 427,835 output tokens, and **$0.243005564** in model costs, with complete usage and billing. Pure installation failures, model execution that had not started at the pause, and offline replays incurred no model charges. The cached PyTorch retry spent 432.8 seconds installing, 140.0 seconds executing the agent, and 23.2 seconds verifying. This reflects the changed cache preparation; it does not show that agent code accelerated the preceding 900-second verifier download. + +**Full 20-task rerun (2026-09-14–15).** The independent full group finished with +**10/20 passes (50%), nine zeros, and one unscored task**. **Nine tasks completed +normally and passed (45%)**. The original 8192 pilot passed 8/20 (40%), with seven +passing trials without a Harbor exception. Circuit's artifacts passed here, but +cost reconciliation reached the execution deadline, so it is not a normally +completed pass. “No Harbor exception” is also not identical to the new definition, +which requires a native `completed` outcome, no error, and no execution deadline. +[Structured results](../../../benchmarks/harbor/results/tb21-tool-input-recovery-20260914.json) +preserve separate attempts, configuration, billing completeness, and validation evidence. + +| Experiment | Tasks | Reward 1 | Reward 0 | Unscored | +| --- | --- | --- | --- | --- | +| Original 8192 pilot | 20 | 8 | 12 | 0 | +| Previous 65536 initial18 | 18 | 5 | 8 | 5 | +| Fresh matching18 subset | 18 | 8 | 9 | 1 | +| Fresh independent full group | 20 | 10 | 9 | 1 | + +Seven of the matching18 subset's eight passes completed normally.

Relative to +the previous 65536 initial18, KV-store changed from zero to a pass, QEMU from +unscored to a pass, and circuit from zero to passing artifacts with a finalization +failure. KV-store and QEMU already passed the original 8192 pilot, and compressor +and regex-log passed their earlier budget supplements. These score changes +therefore do not establish an independent benefit from argument validation. + +The fresh full group recorded **no `ToolInputError` events**. The four offline +replays still provide identical-input evidence, while the targeted scheduler +provides observed live error feedback followed by continued execution and passing +verification. The fresh scheduler failed with `RemoteProtocolError` in request +three, after two completed replies. Its targeted success must not replace this +separate failed attempt. + +Four requests did not return complete responses: Scheme and scheduler lost their +response streams; DNA and path-tracing received `provider_unavailable` errors +referring to SIGTERM and a graceful shutdown timeout. These are transport or +upstream availability failures. Pipeline, regex-chess, and MTEB exhausted fifty +turns; tensor and Caffe completed normally without passing all functional tests. +Model extraction completed twenty-seven replies, installed dependencies, and +entered its single pytest test before exceeding the native 900-second verifier +limit. It remains unscored. This was not a dependency download timeout, and its +deadline was not extended to replace the result. + +**Circuit finalization failure.** Reply fifty finished with `end_turn` at +18:46:26.965 UTC, followed by provider cost reconciliation. The supervisor enforced +the 3600-second execution deadline at 18:47:05.171, interrupting reconciliation +before either `run.completed` or `run.failed` had been written. Native ATIF export +raised `AtifProjectionError: Event Journal has no terminal event`. The experiment +wrapper preserved the original Journal and reconstructed a trajectory with an +explicitly marked synthetic terminal event; it does not claim native export. +Official verification began after the agent stopped and passed all three tests. +This cost-finalization control block is unchanged from the implementation commit's +parent and was not modified here. A follow-up needs to ensure that interrupted +billing reconciliation still records a terminal state and exports a trajectory. +A separate `Gate`-object `KeyError` appeared in model-generated program output and +was returned as a tool result; it was not an agent crash from missing tool arguments. + +Late in circuit, three detailed monitoring probes each exceeded twenty-five +seconds. A read-only check found the container still running at about 1.983/2 GiB +of memory, with Docker not reporting an OOM. Detailed in-container probes were +then stopped in favor of host result files and container state. Agent, verifier, +and resource limits stayed unchanged; no orphaned probe was found. The earlier +probes' contribution to memory pressure is unknown, so this monitoring change +remains an experimental limitation. + +**Trajectories and costs.** All twenty ATIF files validate against Harbor: nineteen +are native exports matching their full Journal projections, and one is the +explicit reconstruction above. No Journal strings were truncated. There were +491 model calls started and 487 complete replies. Fully recorded replies account +for **21,991,162 input tokens**, including **18,119,936 cached tokens**, and +**724,013 output tokens**. Native usage for four interrupted responses remains +incomplete; missing values must not be treated as zero. Per-reply output maxima +also cover completed replies only and do not describe an interrupted response's +actual output. QEMU additionally had one pre-connection `ConnectTimeout` followed +by an SDK retry: forty-one model replies and forty-two HTTP attempts. + +All model costs are covered by native records or separate provider receipts. +Supplemental accounting distinguishes completed replies from interrupted requests +and subtracts costs already recorded in the Journal, avoiding double-counting +when a reconstructed trajectory lacks the native terminal event. The full twenty +tasks cost **$0.462175819**. Including targeted attempts, cached supplements, and +the scheduler whose verification resumed after the pause, total experiment model +cost is **$0.705181383**. Complete billing does not imply complete native responses +or usage. + #### Stopping execution on timeout Timeout handling must ensure that the agent inside the container actually stops before verification begins.
