[Warp Oz third-party harness] Task fails fast: "Harness '<claude|codex>' could not make a successful API request. Matched failure pattern '<p>' in harness output" (credits, invalid key, expired OAuth…

[Warp Oz cloud agents] Setup commands fail with "Permission denied"/EACCES or environment_setup_failed — agent runs as non-root (UID/GID 1000) in a fresh container every run

Cause (Documented platform behavior): Setup commands run in a new container on every run and the agent runs as a non-root user by default. Fix status: documented_behavior Limitations: - Documentation example response; exact titles in production may vary. - Not

[E2B SDK] HTTP 503 'Service temporarily unavailable, please retry.' raises ServiceBusyException/ServiceBusyError — NOT a SandboxException, so generic handlers miss it

Cause (Documented platform behavior): Documented: ServiceBusyException is raised for every 503 and deliberately isn't a SandboxException; the refused call changed nothing (e.g. a refused pause leaves the sandbox running), so it is safe to retry. Fix status: documented_behavior Mi

[Gemini CLI grep/search_file_content] 'Operation timed out after <ms>ms. In large repositories, consider narrowing your search scope by specifying a 'dir_path' or an 'include_pattern'.'

Cause (Documented platform behavior): The grep tool aborts after a fixed timeout and reports the quoted message. Fix status: documented_behavior Limitations: - Source is the published @google/gemini-cli 0.61.0 npm bundle (plus docs at the cited commit); behaviour may differ in

[Gemini CLI policy engine] TOML rule rejected: 'priority must be <= 999 to prevent tier overflow' / 'Invalid policy rule: toolName is required. Use '*' for all tools.' / 'Unsafe regex pattern (potent…

Cause (Documented platform behavior): Zod schema caps priority at 999 within a tier; engine validates required fields; regexes are checked for ReDoS safety. Fix status: documented_behavior Other error fragments: - Invalid policy rule: toolName is required. Use '*' for all

[Warp Oz cloud agents] 401 external_authentication_required: "User is not connected to GitHub" / "User does not have access to the following repositories in the environment"

[Gemini CLI web_fetch] URLs to localhost/private IPs skipped as '[Blocked Host]' ('[WebFetchTool] Skipped private or local host') and per-host rate limit '[Rate limit exceeded]'

Cause (Documented platform behavior): WebFetchTool filters URLs through isBlockedHost (private/local addresses) and a per-host rate limiter before fetching; skipped URLs are reported with those tags instead of being fetched. Fix status: documented_behavior Limitations: - Source i

[Gemini CLI policy engine] 'Security Warning: Skipping system policies from <dir>: ... is not owned by root (uid 0)' / 'is writable by group or others' / Windows ACL 'is insecure'

Cause (Documented platform behavior): To prevent privilege escalation the CLI ignores the standard system policy dir when ownership/permission checks fail; supplemental --admin-policy paths are exempt but are ignored if system policies already exist. Fix status: documented_behavi

[Warp Oz cloud agents] "VM failed before the agent could run. This is likely an issue with your Docker image" — Alpine/musl images unsupported (runtime needs glibc)

Cause (Documented platform behavior): The agent runtime requires glibc; musl-based images are not compatible. Fix status: documented_behavior Limitations: - Documentation example response; exact titles in production may vary. - Not reproduced in this session. Evidence (public sou

[Cursor SDK local shell tool] 'Output notification pattern exceeds 500 characters' — background shell notify pattern rejected; notifications capped (default 100)

Cause (Documented platform behavior): The output observer rejects patterns over 500 characters, compiles them as multiline regex, scans output in 64 KiB chunks and stops emitting after notificationLimit matches (default 100). Fix status: documented_behavior Limitations: - Source
