Persist each Claude OAuth credential's upstream account metadata and one stable device ID, derive one stable session per agent conversation, and keep body and header identity synchronized across Messages, streaming and count_tokens. Alias every cloaked third-party custom tool through caller-stable opaque MCP names and restore declarations, choices, history, references, non-stream responses and SSE events without changing tool ownership. Implement the Claude Code 2.1.220 CCH algorithm over the final serialized request bytes, align currentDate and first-user cache layout, update the official beta/header baseline, and use upstream count_tokens for OAuth and first-party Anthropic credentials. Match the 2.1.220 TLS ClientHello so the transport fingerprint agrees with the identity the request now claims, and document the CLI defaults and automatic OAuth signing / tool alias behaviour in config.example.yaml. --- config.example.yaml | 21 +- .../management/auth_files_provider_oauth.go | 15 +- internal/auth/claude/anthropic.go | 22 +- internal/auth/claude/anthropic_auth.go | 113 +- internal/auth/claude/anthropic_auth_test.go | 111 +- internal/auth/claude/identity.go | 156 ++ internal/auth/claude/identity_test.go | 157 ++ internal/auth/claude/token.go | 12 + internal/config/config_types.go | 9 +- internal/misc/claude_code_instructions.txt | 2 +- internal/runtime/executor/claude_executor.go | 37 +- .../runtime/executor/claude_executor_auth.go | 103 ++ .../executor/claude_executor_auth_test.go | 119 ++ .../executor/claude_executor_cloaking.go | 441 +++-- .../executor/claude_executor_execute.go | 50 +- .../executor/claude_executor_request.go | 344 ++-- .../executor/claude_executor_stream.go | 49 +- .../runtime/executor/claude_executor_test.go | 1468 ++++++++++++++--- .../executor/claude_executor_tokens.go | 71 +- internal/runtime/executor/claude_signing.go | 453 ++++- .../runtime/executor/claude_signing_test.go | 204 +++ .../executor/helps/claude_builtin_tools.go | 30 +- .../helps/claude_builtin_tools_test.go | 27 +- .../executor/helps/claude_client_detection.go | 133 ++ .../helps/claude_client_detection_test.go | 116 ++ .../helps/claude_credential_identity.go | 210 +++ .../helps/claude_credential_identity_test.go | 150 ++ .../executor/helps/claude_device_profile.go | 110 +- .../helps/claude_device_profile_test.go | 101 +- .../executor/helps/claude_mcp_alias.go | 58 + .../executor/helps/claude_mcp_alias_test.go | 64 + .../executor/helps/claude_system_prompt.go | 65 - .../runtime/executor/helps/cloak_utils.go | 73 +- .../runtime/executor/helps/user_id_cache.go | 20 +- .../executor/helps/user_id_cache_test.go | 35 +- .../runtime/executor/helps/utls_client.go | 150 +- .../executor/helps/utls_client_test.go | 393 ++++- .../claude/gemini_claude_request_test.go | 4 +- sdk/auth/claude.go | 12 + 39 files changed, 4875 insertions(+), 833 deletions(-) create mode 100644 internal/auth/claude/identity.go create mode 100644 internal/auth/claude/identity_test.go create mode 100644 internal/runtime/executor/claude_executor_auth_test.go create mode 100644 internal/runtime/executor/claude_signing_test.go create mode 100644 internal/runtime/executor/helps/claude_client_detection.go create mode 100644 internal/runtime/executor/helps/claude_client_detection_test.go create mode 100644 internal/runtime/executor/helps/claude_credential_identity.go create mode 100644 internal/runtime/executor/helps/claude_credential_identity_test.go create mode 100644 internal/runtime/executor/helps/claude_mcp_alias.go create mode 100644 internal/runtime/executor/helps/claude_mcp_alias_test.go delete mode 100644 internal/runtime/executor/helps/claude_system_prompt.go diff --git a/config.example.yaml b/config.example.yaml index 727e2735..4297f407 100644 --- a/config.example.yaml +++ b/config.example.yaml @@ -406,7 +406,7 @@ nonstream-keepalive-interval: 0 # rebuild-mid-system-message: false # optional: default is false; when true, move messages with role "system" into the top-level Claude system field # cloak: # optional: request cloaking for non-Claude-Code clients # mode: "auto" # "auto" (default): cloak only when client is not Claude Code -# # "always": always apply cloaking +# # "always": cloak every unconfirmed client; confirmed native Claude Code still passes through # # "never": never apply cloaking # # This "cloak" block applies to this claude-api-key entry only.

reconstruct cloaked system prompts like the real client Preserve a cloaked caller's own system prompt instead of discarding it, place it as a mid-conversation system turn on models that accept one, and route the remaining legacy models through system reminders. Scope the legacy reminder whitelist to official model IDs. claude-opus-4-6-thinking was dropped: Anthropic publishes no -thinking IDs, that one belongs to the antigravity provider in models.json and is served by a different executor, so it can never reach ClaudeExecutor cloaking. Keeping it implied that synthetic suffixes are normalized here, which they are not, since thinking.ParseSuffix only strips parenthesis suffixes. The map is anchored to the "claude" provider block plus Anthropic's bare and "-latest" aliases, and now covers claude-opus-4-7. --- config.example.yaml | 5 +- internal/config/config_types.go | 6 +- .../executor/claude_executor_cloaking.go | 330 ++++++++----- .../runtime/executor/claude_executor_test.go | 464 +++++++++++++++--- 4 files changed, 608 insertions(+), 197 deletions(-) diff --git a/config.example.yaml b/config.example.yaml index 4297f407..d6f06cc9 100644 --- a/config.example.yaml +++ b/config.example.yaml @@ -412,8 +412,9 @@ nonstream-keepalive-interval: 0 # # credentials, set the same options in the auth/token JSON file via "cloak_mode" / # # "cloak_strict_mode" / "cloak_sensitive_words" / "cloak_cache_user_id".

The credential identity helpers initialized and wrote the map outside claudeDevicePoolMu; only EnsureDeviceIDPool took the lock, so a lazy `auth.Metadata = make(...)` racing a pool write could abort the whole process with "concurrent map writes" instead of failing a request. Locking only the device-pool helpers was not enough: the account-profile and refresh paths kept mutating the same map unguarded, which a concurrency probe surfaced as data races.

The generic pipeline treats any 429 as quota exhaustion: it marks the credential Quota.Exceeded, assigns an exponential cooldown up to 30 minutes and rotates to the next credential, so a single request could walk and cool down the entire Claude pool over a capability the account will never have. Classify it through the existing RequestScopedError contract instead, which already suppresses cooldown, rotation and retry. The status and body are then returned verbatim: the classifier exists to stop the generic pipeline from handling the error, not to handle it. Detection deliberately requires both "fast mode" and a credits phrase, so a genuine rate limit, which never mentions fast mode, keeps its cooldown. Tests cover both observed wordings, byte-exact pass-through, and the negative cases. --- .../claude_executor_beta_policy_test.go | 56 +++++++++++++++++++ .../executor/claude_executor_execute.go | 2 +- .../executor/claude_executor_request.go | 40 +++++++++++++ .../executor/claude_executor_stream.go | 2 +- 4 files changed, 98 insertions(+), 2 deletions(-) diff --git a/internal/runtime/executor/claude_executor_beta_policy_test.go b/internal/runtime/executor/claude_executor_beta_policy_test.go index 6b375d1a..2415e694 100644 --- a/internal/runtime/executor/claude_executor_beta_policy_test.go +++ b/internal/runtime/executor/claude_executor_beta_policy_test.go @@ -3,6 +3,7 @@ package executor import ( "bytes" "context" + "errors" "fmt" "io" "net/http" @@ -213,3 +214,58 @@ func TestApplyClaudeHeaders_FastModePrecedesOAuthTrailer(t *testing.T) { t.Fatalf("Anthropic-Beta = %q, want %s immediately before the OAuth trailer", got, claudeFastModeBeta) } } + +// Anthropic refuses a fast-mode request from an account without the matching +// usage credits with 429 rate_limit_error.

The casing is therefore part of the fingerprint, and six of the eighteen names CPA emits were wrong because Go canonicalises everything passed through Header.Set: anthropic-beta, anthropic-dangerous-direct-browser-access, anthropic-version, x-app, x-client-request-id and X-Stainless-OS. Writing the map keys directly is the only way to keep the original casing. This also fixes ordering at no extra cost. Go sorts header names bytewise when it serialises a request, and the captured order of the real client is exactly that same bytewise sort. Host, User-Agent and Content-Length stay misplaced because Go writes them ahead of the sorted block; a test records that gap and will fail if it ever closes. The pass runs at the send boundary rather than inside applyClaudeHeaders: the rewritten keys are unreachable through Header.Get, and doing it earlier hid these headers from the rest of the pipeline. The boundary is a single doClaudeUpstreamRequest helper pinned by a structural test, after a mutation check showed that dropping the call from the streaming path alone was otherwise undetectable. Expected order is pinned by serialising the request and reading the header lines back, not by inspecting the header map. --- .../executor/claude_executor_execute.go | 2 +- .../executor/claude_executor_request.go | 54 +++++ .../executor/claude_executor_stream.go | 2 +- .../executor/claude_executor_tokens.go | 2 +- .../claude_executor_wire_casing_test.go | 219 ++++++++++++++++++ 5 files changed, 276 insertions(+), 3 deletions(-) create mode 100644 internal/runtime/executor/claude_executor_wire_casing_test.go diff --git a/internal/runtime/executor/claude_executor_execute.go b/internal/runtime/executor/claude_executor_execute.go index d83cb116..e5a478da 100644 --- a/internal/runtime/executor/claude_executor_execute.go +++ b/internal/runtime/executor/claude_executor_execute.go @@ -160,7 +160,7 @@ func (e *ClaudeExecutor) Execute(ctx context.Context, auth *cliproxyauth.Auth, r httpClient := helps.NewUtlsHTTPClient(ctx, e.cfg, auth, 0) httpClient = reporter.TrackHTTPClient(httpClient) - httpResp, err := httpClient.Do(httpReq) + httpResp, err := doClaudeUpstreamRequest(httpClient, httpReq) if err != nil { helps.RecordAPIResponseError(ctx, e.cfg, err) return resp, err diff --git a/internal/runtime/executor/claude_executor_request.go b/internal/runtime/executor/claude_executor_request.go index 599b2a9d..a15e3204 100644 --- a/internal/runtime/executor/claude_executor_request.go +++ b/internal/runtime/executor/claude_executor_request.go @@ -646,6 +646,60 @@ func applyClaudeHeaders(r *http.Request, auth *cliproxyauth.Auth, apiKey string, return nil } +// doClaudeUpstreamRequest is the single send boundary for every Claude upstream +// call.

+0800 Subject: [PATCH 13/38] fix(claude): replay measured OAuth wire, Fast and diagnostic profiles Align the remaining measured OAuth wire profiles, including the ordered connection writer in internal/httpwire that reproduces the observed header sequence, and the refresh/profile response shapes in internal/auth/claude. Replay the measured Fast path and keep diagnostic continuity across cloaked and native requests. Preserve the native direct token-counting shape so a caller that reaches count_tokens itself is not reshaped into the cloaked form. Scope cloak dates to the credential's timezone rather than the host's, so currentDate matches what the real client would have sent for that account. --- config.example.yaml | 1 + internal/auth/claude/anthropic_auth.go | 75 +++-- internal/auth/claude/anthropic_auth_test.go | 151 ++++++++-- internal/auth/claude/oauth_response.go | 61 +++++ internal/auth/claude/oauth_response_test.go | 71 +++++ internal/auth/claude/utls_transport.go | 258 +++++++++--------- internal/auth/claude/utls_transport_test.go | 157 ++++++++++- .../config/claude_header_defaults_test.go | 4 + internal/config/config_normalization.go | 1 + internal/config/config_types.go | 1 + internal/httpwire/ordered_conn.go | 186 +++++++++++++ internal/httpwire/ordered_conn_test.go | 100 +++++++ .../runtime/executor/claude_executor_auth.go | 6 +- .../claude_executor_auth_race_test.go | 30 ++ .../claude_executor_beta_policy_test.go | 21 +- .../executor/claude_executor_cloaking.go | 55 +++- .../executor/claude_executor_diagnostics.go | 90 ++++++ .../claude_executor_diagnostics_test.go | 92 +++++++ .../executor/claude_executor_execute.go | 32 ++- .../executor/claude_executor_fast_fallback.go | 120 ++++++++ .../claude_executor_fast_fallback_test.go | 120 ++++++++ .../executor/claude_executor_request.go | 97 +++++-- .../executor/claude_executor_stream.go | 44 ++- .../runtime/executor/claude_executor_test.go | 136 ++++++++- .../executor/claude_executor_tokens.go | 40 ++- .../executor/helps/claude_diagnostics.go | 91 ++++++ .../executor/helps/claude_diagnostics_test.go | 38 +++ .../runtime/executor/helps/utls_client.go | 78 +++++- .../executor/helps/utls_client_test.go | 27 ++ 29 files changed, 1928 insertions(+), 255 deletions(-) create mode 100644 internal/auth/claude/oauth_response.go create mode 100644 internal/auth/claude/oauth_response_test.go create mode 100644 internal/httpwire/ordered_conn.go create mode 100644 internal/httpwire/ordered_conn_test.go create mode 100644 internal/runtime/executor/claude_executor_diagnostics.go create mode 100644 internal/runtime/executor/claude_executor_diagnostics_test.go create mode 100644 internal/runtime/executor/claude_executor_fast_fallback.go create mode 100644 internal/runtime/executor/claude_executor_fast_fallback_test.go create mode 100644 internal/runtime/executor/helps/claude_diagnostics.go create mode 100644 internal/runtime/executor/helps/claude_diagnostics_test.go diff --git a/config.example.yaml b/config.example.yaml index 7ca4f161..1a69a04d 100644 --- a/config.example.yaml +++ b/config.example.yaml @@ -447,6 +447,7 @@ nonstream-keepalive-interval: 0 # os: "MacOS" # arch: "arm64" # timeout: "600" +# timezone: "Asia/Singapore" # fallback IANA timezone for cloaked currentDate; a credential JSON "timezone" takes priority # stabilize-device-profile: false # optional, default false; set true to enable per-auth/API-key fingerprint pinning # Default headers for Codex OAuth model requests. diff --git a/internal/auth/claude/anthropic_auth.go b/internal/auth/claude/anthropic_auth.go index 710c5ebb..35930164 100644 --- a/internal/auth/claude/anthropic_auth.go +++ b/internal/auth/claude/anthropic_auth.go @@ -8,7 +8,6 @@ import ( "encoding/json" "errors" "fmt" -

charset=UTF-8 Content-Transfer-Encoding: 8bit A Claude Messages request carrying MCP-style tool schemas failed before inference when routed to Antigravity/Gemini: the private backend parses function declarations as a limited proto-JSON Schema and rejects unknown fields, so `propertyNames` produced Unknown name "propertyNames" at 'request.tools[0].function_declarations[0].parameters.properties[0].value' The cleaner already lists `propertyNames` as unsupported, but every cleaning pass is skipped for nodes classified as property maps, and that classification matched any path ending in ".properties". A tool may declare a property named "properties" — Notion's page tools do — and the schema for that property then sits at ".properties.properties", so it was mistaken for a property map and nothing inside it was cleaned. The 400 above points at exactly that node. Replace the suffix match with a parity check over the trailing run of name-map keywords: the node a keyword names is a map only when its own parent is a schema, so "properties" is a map, "properties.properties" is the schema of a property named "properties", and a third repetition is a map again. Only the trailing run is inspected, so a schema nested under any prefix by the caller is classified the same way. Codex/OpenAI egress is untouched: it converts input_schema separately, uses non-strict tool mode, and accepts this shape. --- .../antigravity_schema_sanitize_test.go | 112 ++++++++++++++++++ .../claude/antigravity_claude_request_test.go | 56 +++++++++ internal/util/gemini_schema.go | 34 +++++- internal/util/gemini_schema_test.go | 90 ++++++++++++++ 4 files changed, 291 insertions(+), 1 deletion(-) diff --git a/internal/runtime/executor/antigravity_schema_sanitize_test.go b/internal/runtime/executor/antigravity_schema_sanitize_test.go index ff8c0c21..479207fa 100644 --- a/internal/runtime/executor/antigravity_schema_sanitize_test.go +++ b/internal/runtime/executor/antigravity_schema_sanitize_test.go @@ -456,3 +456,115 @@ func TestSanitizeAntigravityRequestSchemasIsIdempotent(t *testing.T) { } } } + +// propertyNamesShapes are the two nestings reported against the private Gemini backend, which +// rejects the standard JSON Schema keyword "propertyNames" with an unknown-field 400. +var propertyNamesShapes = map[string]string{ + // An object nested in an array item. + "arrayItem": `{"type":"object","properties":{"records":{"type":"array","items":{"type":"object",` + + `"properties":{"name":{"type":"string"}},"propertyNames":{"type":"string"}}}}}`, + // A dynamic map declared by a property that is itself named "properties". + "propertyNamedProperties": `{"type":"object","properties":{"properties":{"type":"object",` + + `"propertyNames":{"type":"string"}}}}`, +} + +// TestSanitizeAntigravityRequestSchemasStripsPropertyNamesEverywhere covers every payload location +// that can carry a schema, in both spellings of the declarations container.

Responses instructions became a leading user turn, a role=system item was only demoted for the first item, role=developer silently became user text, and the Chat translator dropped developer messages outright. An operator instruction could therefore lose its authority or disappear without any signal. All five sources now become separate top-level Claude system blocks in source order, so the executor cloak decides the final placement on its own: a mid-conversation role=system message on models that accept one, an individual block on legacy models. Blocks are never merged, trimmed, reordered or demoted. Anthropic only accepts text in a system slot. Verified against api.anthropic.com: the top-level system field rejects anything else with "system..type: Input should be 'text'", and a role=system message accepts text, tool_addition and tool_removal only. A non-text system part is therefore kept as a typed marker without its payload and rejected by the cloak with a request-scoped 400 that names the offending type. That keeps the failure local, spends no upstream call on a request that cannot succeed, and stops caller content from ever reaching the top-level system field where it would break the Claude Code fingerprint shape. --- .../executor/claude_executor_cloaking.go | 56 +++++++ .../runtime/executor/claude_executor_test.go | 143 +++++++++++++++++ .../executor/claude_executor_tokens.go | 5 + .../chat-completions/claude_openai_request.go | 6 +- .../claude_openai_request_test.go | 57 +++++++ .../claude_openai-responses_request.go | 149 ++++++++++++------ .../claude_openai-responses_request_test.go | 117 ++++++++++++++ 7 files changed, 482 insertions(+), 51 deletions(-) diff --git a/internal/runtime/executor/claude_executor_cloaking.go b/internal/runtime/executor/claude_executor_cloaking.go index db09a6f9..50f38bc3 100644 --- a/internal/runtime/executor/claude_executor_cloaking.go +++ b/internal/runtime/executor/claude_executor_cloaking.go @@ -309,6 +309,55 @@ func claudeUsesLegacySystemReminder(payload []byte) bool { return legacy } +// claudeCallerSystemBlockError reports a caller system block that Claude cannot +// carry in any system slot.

The cause was the beta list, not the translator. Cloaked requests always sent redact-thinking-2026-02-12, which makes Anthropic withhold the summary text even when thinking.display is summarized. Native Claude Code 2.1.220 treats the two as mutually exclusive: the beta is only appended while thinking summaries are off, and the request builder removes it again whenever a display value is attached. An isolated 2.1.220 profile with showThinkingSummaries enabled confirms it on the wire, still on cc_entrypoint=cli, sending display=summarized without the beta and receiving thinking text. A direct A/B against claude-opus-4-8 pins the effect down: with the beta the thinking text is empty for every display value, without it and with display=summarized the text comes back. The beta is now dropped whenever the request carries thinking.display, which is exactly the native rule. Two translation gaps kept the chain lossy on the way back. redacted_thinking blocks had no Responses representation at all and vanished, even though Anthropic requires them to be replayed verbatim; they now ride in encrypted_content behind a marker prefix and are restored as redacted_thinking blocks. Reasoning text was only read from summary[], so a caller whose SDK models the text in content[] lost it; content[] is now used as a fallback, and only as a fallback so a client that mirrors both arrays does not replay the text twice. An item whose encrypted_content is missing or belongs to another provider is still dropped rather than replayed, because Anthropic rejects a thinking block without a signature and there is nothing to synthesize. --- .../executor/claude_executor_request.go | 31 ++++- .../runtime/executor/claude_executor_test.go | 25 ++++ .../claude_openai-responses_request.go | 67 ++++++++-- .../claude_openai-responses_request_test.go | 125 ++++++++++++++++++ .../claude_openai-responses_response.go | 40 ++++-- .../claude_openai-responses_response_test.go | 66 +++++++++ 6 files changed, 328 insertions(+), 26 deletions(-) diff --git a/internal/runtime/executor/claude_executor_request.go b/internal/runtime/executor/claude_executor_request.go index 7ee6bd25..beaf736e 100644 --- a/internal/runtime/executor/claude_executor_request.go +++ b/internal/runtime/executor/claude_executor_request.go @@ -43,6 +43,7 @@ const ( claudeStructuredOutputsBeta = "structured-outputs-2025-12-15" claudeExtendedCacheTTLBeta = "extended-cache-ttl-2025-04-11" claudeCacheDiagnosisBeta = "cache-diagnosis-2026-04-07" + claudeRedactThinkingBeta = "redact-thinking-2026-02-12" ) // claudeCodeCLIConstantBetas are the betas Claude Code 2.1.220 sends on every @@ -50,10 +51,11 @@ const ( // leading claude-code-20250219. // // redact-thinking-2026-02-12 belongs here because cloaked requests always claim -// cc_entrypoint=cli; the "sdk-cli" entrypoint omits it. +// cc_entrypoint=cli; the "sdk-cli" entrypoint omits it.
