Conversation
The Coder wrote architecture.md under a hardcoded 50-step CodeAct budget, so an agent with more than about 20 source files exhausted it and failed the run before any optimization ran. Add coder.architecture_doc_max_iterations, default 100. A @strategy budget is fixed when the class is defined, so create_architecture_doc now builds the CodeAct config from the run configuration and passes it to the generated step.

A bare CodeActStrategy() on the @strategy decorator left the generated step unbounded when it runs without the per-call override: CodeActConfig defaults max_iterations and cell_timeout to None, and nooa reads None as unlimited. That is a worse trap than the hardcoded 50 this branch removed. Derive both the decorator and the per-call config from one helper, so the fallback matches the configured default and the timeout has a single definition. Assert the budget through a real generation run instead of a stubbed method, so the test also covers nooa honoring the override rather than only the kwarg the Coder passes.

…ations Every other numeric field in CoderConfig and its sibling component configs leads with max_ (max_summary_tokens, max_fix_attempts, max_trials, max_depth, max_rounds). architecture_doc_max_iterations was the only one that led with its subject instead. Also settle on one word. The field said iterations, its description said steps, and the documentation said steps. Use iterations everywhere, because that is what nooa's config key and the error a user hits are called, and quote that error in the skill so the two are searchable together.

…s-67e4 main's "resolve every loop seam as a named component" (#1313) renamed the component this branch changes and reshaped how it is configured. Carried this branch's setting across that rename: - Coder -> CodeEditBuilder and CoderConfig -> CodeEditBuilderConfig, so the new max_architecture_doc_iterations field lands on the renamed config. - create_architecture_doc now takes a workdir Path rather than an agent id, so the public wrapper and the generated _create_architecture_doc both take it. - The typed `coder:` run-config block became the free-form `builder_config:` mapping, validated against the component's own config_type. `coder:` is now rejected outright, so the skill documents builder_config.

Summary
The Experimentalist's code-edit builder wrote
architecture.mdunder a hardcoded 50-iteration CodeAct ceiling. An agent with more than about 20 source files exhausted that ceiling, and the resultingGenerationErrorfailed the whole run before any optimization started. The ceiling is now the run-configuration settingbuilder_config.max_architecture_doc_iterations, which defaults to100.Changes
CodeEditBuilderConfig.max_architecture_doc_iterations(default100, must be greater than0). It reaches the component through the existingbuilder_configmapping, which is validated against the component's ownconfig_type, so no call site or CLI flag changes.create_architecture_docinto a small public method that builds the CodeAct configuration fromself._config, and the LLM-generated step_create_architecture_docthat does the work. A@strategyconfiguration is fixed when the class is defined, so the configured value is supplied per call, which is nooa's supported_strategyoverride. The generated step keeps its prompt, itsllm=resolver, and its behavior.describe()remains the Builder verb and still routes through the public method._architecture_doc_codeacthelper. The decorator therefore falls back to the same default, andcell_timeout=3600.0has a single definition.Type of Change
Quality Gates
test_architecture_doc_stops_at_the_configured_iteration_limitinplugins/nemo-experimentalist/tests/experimentalist/test_tools.pydrives a real generation run with a scripted model that never returns a result, so the run can only end by reaching the limit. It was mutation-checked twice, before and again after the merge withmain, and fails for each: pinning the limit back to a literal50, and dropping the_strategyoverride so the decorator's configuration wins.Verification

No intent conflicted; the rename and this setting compose.Reviewer notes
Naming. The setting names the artifact rather than hiding it, because
architecture.mdis a real file in the experiment output, the proposer reads it, and it is the thing that failed. The word "iterations" is deliberate even though no published doc uses it for CodeAct turns: a user reaches this setting after seeing nooa's rawmax_iterations=100, so the name matches what they search for. The leadingmax_matches every sibling field inCodeEditBuilderConfig. Alternatives considered and rejected: a codebase-size hint (unpredictable, cannot rescue an arbitrary shortfall), and a per-step mapping keyed by method name (promotes internal method names to config keys).Scope, worth a decision. This is one of many hardcoded CodeAct ceilings in the plugin. Three others in this same component are
50:apply_change,wire_up_change, and_fix_runtime_issues.apply_changereads the same large codebase, so the same repository that broke the architecture doc may hit that one next, where it surfaces as a killed candidate in the log rather than a setting. Generalizing to one component-wide ceiling was considered and deliberately deferred, becauseoptimize_subproblemlegitimately needs200while the cheap steps do not.Prompt surface. Making the generated step private removes its prompt from
doc(builder), because agentdoc skips underscore-prefixed methods. No sibling method writesarchitecture.md, so this removes prompt noise rather than instructions, but it is a prompt change and not only a configuration change.Summary by CodeRabbit
