[Claude Code] 'Cannot add MCP server to scope: managed' — claude mcp add --scope managed is not writable; managed servers come only from managedMcpServers

Cause (Documented platform behavior): The managed scope is read only from the managedMcpServers managed setting deployed by an organization; the CLI cannot write it. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https

[langchain-aws ChatBedrockConverse/BedrockLLM] ValueError 'Model provider should be supplied when passing a model ARN as model_id' for application/cross-region inference profile ARNs

Cause (Documented platform behavior): langchain-aws derives provider-specific formatting from the model id prefix (anthropic., amazon., meta.); ARNs do not contain it. Fix status: documented_behavior Limitations: - Exact supported kwargs vary by langchain-aws version. Evidence (p

[go-genai Files.UploadFromPath] 'Unknown mime type: Could not determine the mimetype for your file please set the `MIMEType` argument' for .md/.jsonl/.py files or minimal containers

Cause (Documented platform behavior): The SDK infers MIMEType with Go's mime.TypeByExtension, which uses a builtin table plus system mime.types files; unknown extensions return '' and the SDK errors. Fix status: documented_behavior Limitations: - Go's builtin extension table vari

[Strands Agents BedrockModel] Prompt caching silently skipped for application inference profile ARNs — 'model_id=<arn> | cache_config is enabled but this model does not support automatic caching'

Cause (Documented platform behavior): Auto detection checks the model id string for 'claude'/'anthropic'; application profile ARNs carry no model name, so detection returns None and caching is skipped. Fix status: documented_behavior Limitations: - Same class of problem affects o

[google-genai Python] ValueError 'additionalProperties is only supported in Gemini Enterprise Agent Platform mode, , not in Gemini Developer API mode.' for response_schema/Pydantic dict fields

Cause (Documented platform behavior): _raise_for_unsupported_mldev_properties raises for additionalProperties when not in Vertex (Agent Platform) mode; response_schema is converted to the OpenAPI-style Schema type. Fix status: documented_behavior Limitations: - The error message

[MCP Inspector CLI] 'Schema portability: N error(s), M warning(s) across K tools. Re-run with --strict for details.' — legal JSON Schema that MCP clients refuse (bare true/false, array-form type, rem…

Cause (Documented platform behavior): Many MCP clients accept only a narrower subset of JSON Schema than the spec/SDK; the Inspector encodes these consumer limitations as errors (refused outright) or warnings (handled unevenly). Fix status: documented_behavior Other error fragmen

[Kubernetes Pod Security Admission] Deployment/Job applies with only a warning but no Pods appear — ReplicaSet FailedCreate 'violates PodSecurity "restricted:latest"' (enforce applies to Pods, not wo…

Cause (Documented platform behavior): PSA applies warn/audit to workload resources but enforce only to the resulting Pod objects, so the workload is accepted while the controller's Pod creations are rejected. Fix status: documented_behavior Misleading approaches: - Debugging imag

[Amazon Bedrock Mantle (OpenAI-compatible)] Context overflow returns validation_error 'prompt tokens (N) exceed model maximum (M) for <model>' — not recognized by Bedrock-runtime overflow matchers

Cause (Documented platform behavior): Mantle reports overflow as a structured validation_error/invalid_request_error with its own wording rather than the plain-text Bedrock-runtime patterns or OpenAI's code. Fix status: documented_behavior Limitations: - Wording taken from LiteLL

[Anthropic structured outputs / strict tools] Request-wide explicit limits: max 20 strict tools, 24 optional parameters and 16 union-typed parameters across all strict schemas (400 even when each too…

Cause (Documented platform behavior): Documented explicit limits apply to the combined total across all strict schemas in a request; beyond them, internal grammar-size limits produce 'Schema is too complex for compilation.' Fix status: documented_behavior Misleading approaches: -

[mcp-publisher publish] server.json validation: 'version must be a specific version, not a range' / 'version string 'latest' is reserved' / 'template variables in URL ... reference undefined variable…

Cause (Documented platform behavior): Registry requires exact versions, only declared URL template variables, bounded publisher metadata and canonical argument encoding. Fix status: documented_behavior Other error fragments: - version string 'latest' is reserved and cannot be use

[go-genai Live] 'live module requires APIVersion to be set. You can set APIVersion to v1beta1 for BackendVertexAI or v1apha for BackendGeminiAPI' (note typo 'v1apha')

Cause (Documented platform behavior): Live.Connect reads the client-level HTTPOptions.APIVersion and rejects empty values and per-request HTTPOptions. NewClient normally fills v1beta1 (Vertex) or v1beta (Gemini API) when unset. The message's suggested Gemini value is misspelled '

[Amazon Bedrock] Context-window overflow has no single error code — model-specific messages ('Input is too long for requested model', 'input length and `max_tokens` exceed context limit', 'too many t…

Cause (Documented platform behavior): Bedrock forwards model-specific validation text; there is no dedicated error code. Frameworks maintain substring lists: Strands (BEDROCK_CONTEXT_WINDOW_OVERFLOW_MESSAGES) and LiteLLM (_map_bedrock_exception) each list different variants. Fix

[Amazon Bedrock Runtime] ModelTimeoutException (HTTP 408) and ModelErrorException / ModelStreamErrorException (HTTP 424) — non-standard statuses that generic retry classifiers mis-handle

Cause (Documented platform behavior): The bedrock-runtime API model defines ModelTimeoutException with httpStatusCode 408 and ModelErrorException/ModelStreamErrorException with 424 (both marked senderFault); ModelStreamErrorException's docs say to retry the request. Fix status: d

[mcp-publisher] DNS/HTTP login fails 'timestamp outside valid window (±15 seconds)' (clock skew) or 'github.io domains cannot be used with DNS/HTTP authentication'

Cause (Documented platform behavior): The client signs a timestamp that the registry accepts only within ±15 s; github.io domains are refused for domain auth and must use GitHub auth (io.github.* namespace). Fix status: documented_behavior Other error fragments: - github.io domai

[Amazon Bedrock Converse + Llama/Mistral] ValidationException 'messages.N.content: Conversation blocks and tool result blocks cannot be provided in the same turn.'

Cause (Documented platform behavior): For some Bedrock model families a toolResult user turn must contain only tool results; text/media must be in a separate user turn (separated by an assistant turn because Bedrock merges consecutive same-role turns). Fix status: workaround_only

[Anthropic Go/C# SDK cloud clients] 'no workspace ID found; set WorkspaceID ... ANTHROPIC_AWS_WORKSPACE_ID' and 'no base URL found' (Claude Platform on AWS / Google Cloud clients)

Cause (Documented platform behavior): These clients require a workspace ID on every request and resolve the endpoint from BaseURL or region; values come from ClientConfig or env vars ANTHROPIC_AWS_WORKSPACE_ID/ANTHROPIC_AWS_BASE_URL/AWS_REGION or ANTHROPIC_GOOGLE_CLOUD_PROJECT/AN
