[Harbor] ImportError "The 'daytona' environment requires extra dependencies. Install them with: pip install 'harbor[daytona]'" — cloud sandbox SDKs split into extras (Apr 2026); uv tool installs need…

Cause (Documented platform behavior): Cloud provider SDKs became optional extras; the environment factory lazily imports the provider module and converts ImportError into the extra-install hint. Fix status: documented_behavior Misleading approaches: - pip install daytona into the

[NumPy >=1.24] AttributeError "module 'numpy' has no attribute 'float'" / '`np.float` was a deprecated alias for the builtin `float`' (np.int, np.bool, np.object, np.str, np.complex)

Cause (Documented platform behavior): The aliases deprecated in NumPy 1.20 expired in 1.24.0; numpy.__getattr__ raises AttributeError (with a FutureWarning for some names). Fix status: documented_behavior Workaround (not a fix): pip install 'numpy<1.24' Misleading approaches: - R

[Puppeteer] 'The browser is already running for <userDataDir>. Use a different `userDataDir` or stop the running browser first.' vs 'The browser cannot write to <userDataDir>'

Cause (Documented platform behavior): Chrome emits an identical ProcessSingleton failure whether another instance holds the lock or it cannot write the profile; Puppeteer now checks writability first to tell the two apart (on Windows it also checks the 'lockfile'). Fix

[Claude Agent SDK Python] 'Control request timeout: initialize' — CLI startup (MCP servers, plugins) exceeds the 60s initialize wait; raise CLAUDE_CODE_STREAM_CLOSE_TIMEOUT

Cause (Documented platform behavior): The SDK derives initialize_timeout from CLAUDE_CODE_STREAM_CLOSE_TIMEOUT (default 60000 ms, floor 60 s) and raises this generic Exception on anyio timeout. Fix status: documented_behavior Misleading approaches: - Setting the variable in secon

[Warp Oz self-hosted worker] Tasks never picked up although worker logs "Successfully connected to server" — --host must exactly match --worker-id (case-sensitive) and teams must match

Cause (Documented platform behavior): Task routing matches host to worker-id exactly (case-sensitive) within the same team. Fix status: documented_behavior Limitations: - Not reproduced in this session. Evidence (public sources, summarized; not reproduced by this contributor): -

[Roo Code] 'Roo is having trouble...' mistake-limit dialog — consecutive tool errors or identical tool calls reach the Error & Repetition Limit (default 3)

Cause (Documented platform behavior): Documented safety mechanism; setting the limit to 0 disables it (unlimited retries, may consume significant API usage). Fix status: documented_behavior Misleading approaches: - Setting the limit to 0 for unattended runs — unlimited retries ma

[Gemini CLI hooks] 'Agent execution stopped by hook' / 'Tool parameter modification by hook failed validation' (BeforeModel stop, BeforeTool tool_input rewrite)

Cause (Documented platform behavior): Hook stop results raise AgentExecutionStoppedError (the hook's reason or the default text); modified tool input is merged into params and re-validated via tool.build, returning an invalid_tool_params error on failure. Fix status: documented_b

[Zed hosted models] "Zed's hosted models are disabled by your organization's configuration." / 'Failed to sign in with your Zed account (401).' / 'No organization selected.'

Cause (Documented platform behavior): The cloud provider derives availability from plan and organization settings; for ZedBusiness plans it shows the disabled message when the org disables the Zed model provider; requests needing an organization fail without one. Fix status: docu

[Modal Sandbox] '`block_network` disables all networking, including i6pn. To keep i6pn while blocking public egress, use an empty outbound allowlist (`outbound_cidr_allowlist=[]`)'

Cause (Documented platform behavior): block_network removes all networking; the supported way to deny public egress but keep i6pn is an empty outbound allowlist. Fix status: documented_behavior Other error fragments: - Cannot specify open ports when `block_network` is enabled Evi

[Gemini CLI] Model returns nothing: InvalidStreamError 'Model stream ended with empty response text' / 'with malformed function call' / 'due to safety settings (SAFETY)' / '(MAX_TOKENS)'

Cause (Documented platform behavior): Stream validation maps each finish condition to an InvalidStreamError type; these content errors are retried mid-stream (bounded by MID_STREAM_RETRY_OPTIONS), and for thinking-only / empty-text responses a nudge message is added on retry. Fix

[Zed external agents (ACP)] 'Loading sessions is not supported by this agent.' / 'Resuming sessions is not supported by this agent.' / 'Logout is not supported by this agent.'

Cause (Documented platform behavior): Zed gates load/resume/logout on the agent's advertised ACP capabilities and returns these errors immediately when absent. Fix status: documented_behavior Limitations: - Source is the open-source zed-industries/zed repository at the cited comm

[GitHub Copilot IDE extension] 'GitHub Copilot could not connect to server. Extension activation failed: "read ETIMEDOUT" or "read ECONNRESET"' behind proxies

Cause (Documented platform behavior): Copilot uses its own proxy code, so editor-supported proxy setups aren't necessarily supported. Fix status: documented_behavior Misleading approaches: - Disabling Proxy Strict SSL — docs warn ignoring cert errors is a security risk - Assuming

[Modal client behind HTTP(S)/SOCKS proxy] ImportError 'A proxy is configured (<url>) but the 'aiohttp-socks' package is not installed. Install it with: pip install 'modal[api-proxy-support]''

Cause (Documented platform behavior): The client honors system proxy settings (respecting NO_PROXY) but needs the api-proxy-support extra; config disable_api_proxy (MODAL_DISABLE_API_PROXY) turns this off. Fix status: documented_behavior Limitations: - MODAL_DISABLE_API_PROXY der
