Summary
Implements full OpenRouter provider support in the ProviderRegistry, enabling users to seamlessly integrate OpenRouter as an LLM provider alongside existing providers. This resolves the
ValueError: Unsupported provider type: openroutererror and provides complete configuration, testing, and documentation for the OpenRouter integration.Changes

Implementation Attempt — Tier 1: haiku — Success
Fixed the failing
CI / lintcheck (which also causedCI / status-checkto fail).The root cause was that
ruff format --checkwas failing on two files that had been committed without running the formatter:features/steps/openrouter_provider_registry_steps.py— a@when(...)decorator was split across 3 lines but ruff preferred a single linesrc/cleveragents/providers/registry.py— akwargs.pop(...)call was split across 3 lines but ruff preferred a single lineFix applied: ran

The openrouter_provider_registry_steps.py file called use_step_matcher("re") at module level without restoring the default "parse" matcher at the end. This caused all step files loaded alphabetically after it (provider_registry_*, resource_*, session_*, etc.) to use the regex matcher instead of the parse matcher, breaking their {value}-style step patterns and causing unit_tests CI failures. Add use_step_matcher("parse") at the end of the file to restore the default matcher after the openrouter step definitions are registered.Implementation Attempt — Tier 3: sonnet — Success
Fixed the failing
CI / unit_testscheck (which also causedCI / status-checkto fail).Root cause:
features/steps/openrouter_provider_registry_steps.pycalleduse_step_matcher("re")at module level without restoring the default"parse"matcher at the end of the file. Behave loads step files in alphabetical order, so all step files loaded afteropenrouter_provider_registry_steps.py(includingprovider_registry_coverage_steps.py,provider_registry_steps.py,resource_*_steps.py,session_*_steps.py, etc.) inherited the regex matcher. These files use parse-style{value}patterns which are not valid regex patterns, causing step matching failures across hundreds of scenarios.Fix applied: Added

This PR cannot be approved because the CI pipeline is failing. Specifically, the "unit_tests" check has failed (status: "failure"). Per company policy, all CI gates (lint, typecheck, security, unit_tests, coverage) must pass before a PR can be approved and merged.
Please investigate and fix the failing unit tests. Once CI is passing, request another review.

No duplicate found.
📋 Estimate: tier 1.
4-file additive PR (registry implementation + BDD feature file + step definitions + docs), 612 LOC. Core logic adds a new ProviderType.OPENROUTER case to _create_provider_llm — mechanical pattern match against existing providers. The complexity is the failing CI: unit_tests shows 1 scenario failed and 26 errored steps, with a "traceback outside scenario" pattern indicating BDD test setup/teardown issues. The step definitions explicitly use regex matchers to avoid ambiguity with existing steps, suggesting step-conflict debugging was anticipated. Fixing requires cross-file context across feature file, steps, and existing BDD test infrastructure. Standard tier-1 engineering work: multi-file, touches test infrastructure, requires cross-file reasoning to resolve CI failures.

534a68e.The _create_provider_instance method had two ProviderType.OPENROUTER branches. The first (lines 574-598) ran first, returning without sanitizing numeric header keys. The second (correct) branch at lines 627-652 — which coerces all header keys/values to str — was dead code and never reached. Fix: remove the first (broken) branch so the sanitizing branch executes. Also add _create_provider_llm as a thin wrapper around _create_provider_instance. Three scenarios in openrouter_provider_registry.feature called this method and received AttributeError because it did not exist.
