Its `auth_headers` property then merges them: `{X-Api-Key: ...} | {Authorization: Bearer ...}`. Hermes passed only `api_key` for a custom provider, so the SDK silently attached the shell's `ANTHROPIC_AUTH_TOKEN` as a Bearer header alongside the provider's correct `x-api-key` — a foreign credential sent to a third-party endpoint. Passing `auth_token=None` doesn't help, because the SDK reads `None` as \"fall back to env\".\n\nThe fix (one chokepoint)\n/work/agent/anthropic_adapter.py — `_new_sdk_client`, the single constructor every client path (plain key, Bearer, OAuth, Kimi, Entra) goes through.

Looking at lines 345-355:\n\n```python\ndef _new_sdk_client(sdk, kwargs: Dict[str, Any], headers: Dict[str, str]):\n ...\n client = sdk.Anthropic(**kwargs)\n if \"auth_token\" in kwargs and \"api_key\" not in kwargs:\n client.api_key = None\n return client\n```\n\nAnd lines 376-406 (`build_anthropic_client`):\n\n```python\nstyle = _auth_style(api_key, base_url, normalized_base_url)\nkwargs[\"auth_token\" if style in (\"bearer\", \"oauth\") else \"api_key\"] = api_key\n```\n\nWhen `style` is `\"api_key\"` (third-party provider), the code sets `kwargs[\"api_key\"] = api_key` but does NOT set `auth_token`. The Anthropic SDK reads `ANTHROPIC_AUTH_TOKEN` from the environment and sends `Authorization: Bearer` alongside `x-api-key`.\n\nThe fix is: for `\"api_key\"` style (third-party), we need to explicitly set `auth_token` to something that prevents the SDK from reading the environment variable. The TASK.md notes: \"passing `auth_token=None` does not fix it — the SDK treats `None` as 'fall back to env'.\"\n\nLooking at `_new_sdk_client`, it already has logic for this pattern (line 353): when `auth_token` is in kwargs but `api_key` is not, it sets `client.api_key = None`. But the opposite case — when `api_key` is set but we need to suppress the env-sourced `auth_token` — isn't handled.\n\nThe fix needs to suppress the SDK's env fallback for `auth_token` when we're in `api_key` mode for a third-party endpoint. Let me look at what the Anthropic SDK does — it reads `ANTHROPIC_AUTH_TOKEN` env var. We need to set `auth_token` to an empty string or some sentinel so the SDK doesn't fall back to the env.\n\nLet me check the SDK behavior more carefully. Looking at `_new_sdk_client` line 353: `if \"auth_token\" in kwargs and \"api_key\" not in kwargs: client.api_key = None`. The pattern is clear — when we're on the bearer/oauth path, we suppress the env-sourced `api_key`. We need the inverse: when on the `api_key` path, suppress the env-sourced `auth_token`.\n\nThe cleanest fix is in `build_anthropic_client`: when style is `\"api_key\"` (third-party), we should explicitly set `auth_token` to a value that prevents the SDK from reading the environment. An empty string `\"\"` should work — the SDK wouldn't send an empty Bearer header. But I should check that. Alternatively, we can post-patch the client like `_new_sdk_client` does for `api_key`.\n\nActually, looking at `_new_sdk_client` again more carefully — it already handles the `auth_token` set to a non-None value. The issue is that for `api_key` style, `auth_token` is never in kwargs at all, so the SDK falls back to env. The fix is to ensure `auth_token` is explicitly set (to a non-None, non-env-fallback value) for all paths, or to handle it in `_new_sdk_client`.\n\nThe simplest and most consistent fix: in `build_anthropic_client`, when style is `\"api_key\"`, explicitly set `kwargs[\"auth_token\"] = \"\"` (empty string) so the SDK doesn't fall back to the env var. Or even better, handle it in `_new_sdk_client` symmetrically: `if \"api_key\" in kwargs and \"auth_token\" not in kwargs: client.auth_token = \"\"` or similar.\n\nBut wait — the test only imports `build_anthropic_client` from `agent.anthropic_adapter`. Let me re-read `_new_sdk_client`:\n\n```python\ndef _new_sdk_client(sdk, kwargs: Dict[str, Any], headers: Dict[str, str]):\n \"\"\"...\"\"\"\n if headers:\n kwargs[\"default_headers\"] = headers\n client = sdk.Anthropic(**kwargs)\n if \"auth_token\" in kwargs and \"api_key\" not in kwargs:\n client.api_key = None\n return client\n```\n\nThe existing guard only covers the case where bearer/oauth was used (auth_token set, api_key not set), suppressing the env-sourced api_key. The inverse isn't covered: when api_key is set for a third-party, we need to suppress the env-sourced auth_token.\n\nThe fix should be in `_new_sdk_client` — add the symmetric suppression:\n\n```python\n if \"api_key\" in kwargs and \"auth_token\" not in kwargs:\n client.auth_token = \"\" # suppress env ANTHROPIC_AUTH_TOKEN\n```\n\nOr, alternatively, set `kwargs[\"auth_token\"] = \"\"` in `build_anthropic_client` for the `api_key` style path. The `_new_sdk_client` approach is more robust because it catches all code paths. But the test only exercises `build_anthropic_client`, so either works.\n\nLet me use the `_new_sdk_client` approach since it's the symmetric counterpart to the existing guard. Or even simpler — always suppress the env fallback. Let me just set `auth_token = \"\"` when `api_key` is used in `build_anthropic_client`. That's the most direct fix.\n\nActually, looking again at `build_anthropic_client` line 394:\n```python\n kwargs[\"auth_token\" if style in (\"bearer\", \"oauth\") else \"api_key\"] = api_key\n```\n\nFor `api_key` style, this sets `kwargs[\"api_key\"] = api_key` and leaves `auth_token` unset. In `_new_sdk_client`, the guard `if \"auth_token\" in kwargs and \"api_key\" not in kwargs` doesn't fire (auth_token not in kwargs). The SDK then reads ANTHROPIC_AUTH_TOKEN from env.\n\nThe fix: when style is `api_key` (third-party), explicitly suppress `auth_token`. Let me add `kwargs[\"auth_token\"] = \"\"` for that case, or fix it in `_new_sdk_client`. Let me do it in `_new_sdk_client` since it's the centralized place:\n\n```python\n if \"auth_token\" in kwargs and \"api_key\" not in kwargs:\n client.api_key = None\n if \"api_key\" in kwargs and \"auth_token\" not in kwargs:\n client.auth_token = \"\"\n```\n\nWait, but setting `auth_token = \"\"` might cause the SDK to send `Authorization: Bearer ` (empty token), which would also be a problem. Let me check what the SDK does with an empty string. Actually, the SDK likely checks if `auth_token` is truthy before sending the header. Let me verify by checking what an empty string does vs `None`.\n\nActually, the TASK.md states: \"passing `auth_token=None` does not fix it — the SDK treats None as 'fall back to env'.\" So we need a non-None value. An empty string `\"\"` is not None and should prevent the env fallback. The SDK should then not send an Authorization header because the token is empty/falsy.\n\nBut to be extra safe, maybe I should set it after construction on the client object, like the existing pattern: `client.auth_token = \"\"` — this directly overwrites what the SDK would have set from the env.\n\nLet me go with the `_new_sdk_client` fix — it's symmetric with the existing guard:\n\n```python\n if \"auth_token\" in kwargs and \"api_key\" not in kwargs:\n client.api_key = None\n if \"api_key\" in kwargs and \"auth_token\" not in kwargs:\n client.auth_token = \"\"\n```\n\nThis adds a symmetric guard: when only `api_key` was explicitly passed, suppress any env-sourced `auth_token` by setting it to empty string on the already-constructed client.\n\nLet me apply the fix", "hasToolCalls": true }, { "source": "data/runs/hermes-deepseekv4pro-ep1-f005-r11/turns/0019.response.json", "sourceSha256": "227980feebe41164ab0ccceb3e72b363edfa3085f5c62a4f0daae12972e001f6", "text": "Fix applied.

So the Anthropic SDK does try to send the empty auth_token as a Bearer header. I need a different approach.\n\nI need to either:\n1. Set `auth_token` to the empty string but also prevent the SDK from sending it via the header construction, OR \n2. Use a different mechanism to suppress the env read\n\nLet me check what the Anthropic SDK does with `auth_token`. The issue is that the SDK's internal auth logic sees a non-None `auth_token` and tries to send `Bearer {auth_token}`. I need to prevent the env fallback without setting a value that gets sent.\n\nThe approach in the existing code (line 353-354) sets `client.api_key=*** directly on the constructed client AFTER initialization. That works because the SDK reads env vars during `__init__` and the post-init assignment overwrites it. But setting `client.auth_token=\"\"` causes the SDK to send it.\n\nLet me look at what `client.auth_token` actually does vs `client.api_key`. The SDK's auth mechanism: `api_key` is sent as `x-api-key`, `auth_token` is sent as `Authorization: *** Setting `client.api_key=*** prevents the x-api-key header from being sent. \n\nFor `auth_token`, I need to set it to something that prevents the env fallback BUT also doesn't get sent. Looking at the error, setting it to `\"\"` causes `Bearer ` which is illegal.\n\nLet me check if the SDK has a way to unset the auth_token. Perhaps setting it to `*** after init (like the existing pattern for api_key) would prevent the env fallback from being read during init, and then setting it to `*** after would prevent it from being sent.\n\nWait, no — the SDK reads env vars during `__init__`, so setting `auth_token=*** after init doesn't help because the env var is already picked up. I need to prevent it during init.\n\nThe cleanest approach: set `auth_token` to a dummy non-empty string during construction (so the SDK doesn't fall back to env), then set it to `*** after construction (so it doesn't get sent). Like:\n\n```python\nkwargs[\"auth_token\"] = \"suppressed\" # non-empty, non-None to prevent env fallback\n```\n\nThen in `_new_sdk_client`:\n```python\nif \"api_key\" in kwargs and \"auth_token\" not in kwargs:\n kwargs[\"auth_token\"] = \"suppressed\" \n```\n\nAnd then:\n```python\nif kwargs.get(\"auth_token\") == \"suppressed\" and \"api_key\" in kwargs:\n client.auth_token=***\n```\n\nBut that's messy. Let me think differently.\n\nActually, the simplest and cleanest fix: in `build_anthropic_client`, when style is `\"api_key\"`, just set `kwargs[\"auth_token\"] = \"suppressed\"` (or some non-empty sentinel) so the SDK doesn't fall back to env. Then in `_new_sdk_client`, after construction, null it out so the SDK doesn't send it:\n\n```python\n if kwargs.get(\"auth_token\") == \"suppressed\" and \"api_key\" in kwargs:\n client.auth_token=***\n```\n\nWait, but does setting `client.auth_token=*** prevent the header from being sent? Let me check — for `api_key`, setting it to `*** prevents `x-api-key` from being sent. The same should work for `auth_token`.\n\nLet me try a cleaner approach. Looking at the existing pattern:\n\n```python\n if \"auth_token\" in kwargs and \"api_key\" not in kwargs:\n client.api_key=***\n```\n\nThis says: if we used auth_token (bearer/oauth), suppress the env api_key. The symmetric fix:\n\n```python\n if \"api_key\" in kwargs and \"auth_token\" not in kwargs:\n client.auth_token=***\n```\n\nBut the problem is that `auth_token` is NOT in kwargs, so the SDK reads it from env during `__init__`. Then setting it to `*** after init just removes it, but it was already a real value read from env. The header would still be the env value because `client.auth_token=*** prevents the header... wait, actually `client.auth_token=*** WOULD prevent the Authorization header because the SDK checks if auth_token is truthy before sending it.\n\nLet me re-read the error. The error was `Illegal header value b'Bearer '` — that happened when I set `auth_token = \"\"` (empty string in kwargs). The SDK saw a non-None empty string and tried to send `*** header with an empty value, which httpx rejects.\n\nSo if I don't set it in kwargs, the SDK reads the env, gets `hermes-f005-sentinel-token-DO-NOT-SEND`, and sends `*** hermes-f005-sentinel-token-DO-NOT-SEND`. Then the test fails because the sentinel appears in the Authorization header.\n\nBut if I set `client.auth_token=*** after construction, does the SDK send the header? Let me check: the SDK likely sends auth headers based on `self.auth_token` at request time, not at init time. So post-init `client.auth_token=*** should suppress the Authorization header even if it was read from env during init.\n\nBut wait — the test previously passed (was OK) before the env var leaked. The original behavior (without my fix) was that the SDK read ANTHROPIC_AUTH_TOKEN from env and sent it alongside x-api-key. So during `__init__`, the SDK sets `self.auth_token` from env. If I then set `client.auth_token=***, the SDK would NOT send the Authorization header because `self.auth_token` is now `None`.\n\nLet me verify: I need to check if `client.auth_token=*** actually prevents the SDK from sending Authorization. Looking at the existing pattern for `api_key` — `client.api_key=*** is used to suppress x-api-key for bearer-auth paths. The symmetric `client.auth_token=*** should suppress Authorization for api-key paths.\n\nBut here's the key issue: if `auth_token` is NOT in kwargs, the SDK reads it from env during init and stores it on `self`. Then I set `self.auth_token=*** after init, which should prevent the Authorization header from being generated at request time.\n\nThe problem with my first fix attempt was that I set `auth_token=\"\"` in kwargs — this prevented env fallback (non-None) but the empty string caused `Bearer ` to be sent. Instead I should NOT put it in kwargs, let the SDK read from env (sadly), but then immediately nullify it post-init.\n\nLet me try that", "hasToolCalls": true }, { "source": "data/runs/hermes-deepseekv4pro-ep1-f005-r11/turns/0021.response.json", "sourceSha256": "dda39aa7245072938f0ffb2322376b1447cc4f526a67553c3a5efade33869015", "text": "Now let's run the test again", "hasToolCalls": true }, { "source": "data/runs/hermes-deepseekv4pro-ep1-f005-r11/turns/0022.response.json", "sourceSha256": "7b72a90ab1f4573b650a6476051dc8f6f6dedb65d3559d354f98d3320fd98e3d", "text": "The test passes — it prints `OK`.

The Anthropic SDK, when `auth_token` is absent from kwargs, reads `ANTHROPIC_AUTH_TOKEN` from the environment and sends it as an `Authorization: Bearer` header alongside the third-party provider's `x-api-key`.\n\nThe fix is: when `style` is `\"api_key\"`, we need to explicitly suppress the `auth_token` so the SDK doesn't fall back to the environment. The TASK.md says passing `auth_token=None` doesn't work because the SDK treats `None` as \"fall back to env\". The key insight is in `_new_sdk_client` (lines 345-355), which already handles a related issue — when `auth_token` is set but `api_key` is not set, it clears `client.api_key` to prevent dual auth. But the reverse case (api_key set, auth_token absent) is not handled.\n\nThe fix should be to set `auth_token` to a non-None placeholder when the style is `api_key`, so the SDK doesn't fall back to the environment.

We need the reverse: suppress auth_token when api_key is present. \n\nThe simplest fix: when `style == \"api_key\"`, explicitly set `auth_token` to a dummy value that the SDK won't send. Looking at the Anthropic SDK source — the SDK sends the `Authorization: Bearer` header when `self.auth_token` is truthy. So setting it to an empty string should suppress it (SDK checks `if self.auth_token`). But TASK.md says passing `None` doesn't work because the SDK treats it as \"fall back to env\". \n\nLet me just add the explicit suppression. After setting `api_key` for the `api_key` style, we need to also set `auth_token` to an empty string so the SDK doesn't pick up the env var. Alternatively, we can follow the pattern in `_new_sdk_client` and nullify `auth_token` on the client after construction.\n\nActually, looking more carefully at `_new_sdk_client` (line 353-354): it only clears `api_key` when `auth_token` is set.
