All LLM IO now flows + through `libs/openant-core/utilities/llm/`, a Protocol-based + adapter layer with one provider plugin per file in + `utilities/llm/providers/`. Three adapters ship today — + **Anthropic** (reference), **OpenAI** (Chat Completions), and + **Google Gemini** (`google-genai` SDK) — all supporting tool + calling. Adding more (Ollama, vLLM, OpenRouter-native, etc.) is + a small Python adapter recipe — plus a few Go wizard/probe + touch-points if you want it offered by `openant setup llm`; see + `docs/features/llm-providers/HOW_TO_ADD_AN_ADAPTER.md`. The + surface is deliberately minimal — one `complete()` method, one + `validate()` method, a closed set of three content-block kinds, + a five-class error taxonomy. Closes #65. + +- **Per-phase llm-configs.** `~/.config/openant/config.json` now + accepts an `llm_configs` section that maps each of the seven + pipeline phases (`analyze`, `enhance`, `verify`, `report`, + `dynamic_test`, `llm_reach`, `app_context`) to a + `{provider, model}` pair. Users pick an llm-config via + `openant scan --llm-config `. The built-in `openant-default` + config (source-defined, frozen) pins today's per-phase Claude + defaults, so existing users see no behavior change: a fresh + install with no `llm_configs` resolves to `openant-default` and + runs against Anthropic with the same model IDs as before. + +- **`openant setup llm` interactive wizard.** Walks the user + through creating a named llm-config without hand-editing JSON. + Per-phase per-provider model defaults (e.g. `gpt-4o` for + analyze, `gpt-4o-mini` for app_context, `gemini-1.5-pro` for + verify), known-models hint shown once per provider per session, + overwrite confirmation, and a 1-token probe per unique + (provider, model) pair before save so a typo'd key surfaces + immediately. Includes a heads-up that ChatGPT / Codex + subscriptions don't grant OpenAI API quota. + +- **Eager provider validation.** When a scan starts, the registry + instantiates one adapter per unique provider in the resolved + llm-config and exposes a `validate()` method that probes each + unique `(provider, model)` pair with a 1-token call. Catches + typo'd model IDs, revoked keys, and broken endpoints before the + user starts a paid scan. Standalone step verbs (`openant analyze`, + `verify`, etc.) probe their own registry at startup too. + +- **Tool-support gating at config-validation time.** Phases that + use tool calling (`enhance`, `verify`) refuse to bind to a + provider whose adapter sets `supports_tools = False`. Error + message names the phase, the offending provider, and what to do + about it — fails at registry-build time, never at first call. + +- **Contract test harness.** A 12-test parametrised suite runs + against every shipped adapter (36 cases across Anthropic, OpenAI, + Google; one tool-related case skips per adapter depending on + `supports_tools`, so all three tool-capable shipped adapters + execute 11 and skip 1) pinning each one's behaviour for text + completion, tool-use round trips, and error mapping. Adding an + adapter means adding one scenario factory file and one row in + `tests/test_llm_adapter_contract.py::ADAPTERS`. + +### Changed + +- **`--model opus|sonnet` removed.** Both Go and Python CLIs replace + it with `--llm-config ` across `scan`, `analyze`, `enhance`, + `verify`, `dynamic-test`, and `report`. Backwards compatibility: + `~/.config/openant/config.json` files that only have the legacy + top-level `api_key` field auto-migrate in memory to a synthetic + `llm_providers["anthropic"]` entry, so `openant scan` keeps + working unchanged for upgrade users. + +- **JSON-correction calls now inherit the parent phase's binding.** + The legacy code hardcoded Sonnet for JSON correction regardless + of the analyze phase's model. With per-phase configs this stops + generalising — correction calls now use the same provider+model + as the call whose response failed to parse. For all-Anthropic + users this is a small cost bump on Opus-phase corrections; for + non-Anthropic users it's the only correct behavior. + +- **Unknown-model cost reporting is honest.** The pricing table + used to fall back to Sonnet rates for any unknown model ID, + which produced plausible-but-wrong totals on OpenRouter runs. + Unknown IDs now report `$0` with a one-time stderr warning. + Each adapter ships its own per-model pricing table; add entries + locally if you scan against a newer model the adapter doesn't + list yet. + +### Fixed + +- **Reporter no longer crashes on non-string response fields.** + Some non-Anthropic models return structured dicts where the + analyze prompt asked for plain strings (e.g. `attack_vector` as + a JSON object instead of a quoted attack description). The + reporter's `"\n\n".join(parts)` then raised + `TypeError: sequence item 0: expected str instance, dict found` + mid-scan. `core/reporter.py:_coerce_to_str` now defensively + serialises non-string values at every consumption site; the + analyze prompt has been tightened to require string types + explicitly. + +### Removed + +- **`AnthropicClient` class deleted** from + `libs/openant-core/utilities/llm_client.py`. The file remains + for `TokenTracker` (still shared across all adapter call sites) + but the LLM-wrapper class is gone — every caller now uses + `simple_text(binding, prompt, ...)` (for text-only phases) or + `binding.adapter.complete(...)` (for tool-using phases) from + `utilities.llm`. + +- **`OPENANT_LLM_BASE_URL` / `OPENANT_LLM_API_KEY` / + `OPENANT_LLM_MODEL` env vars are gone** (they were never in a + release).

The 12 contract tests run automatically against your adapter once it's wired in.
