Proposed fix: [lm-evaluation-harness] multiple_choice tasks (MMLU, ARC, HellaSwag) fail on chat-completions APIs: 'Loglikelihood ... is not supported for chat completions'

Recommended action: For API-only chat models use generative variants of tasks (e.g. *_generative / CoT tasks with answer extraction). For self-hosted models, serve them with an OpenAI-compatible /v1/completions endpoint (vLLM etc.) and use local-completions, or run the model dire

Proposed fix: [ESLint 10] Monorepo/subdirectory linting picks a different config: eslint.config.* now looked up from each linted file's directory (v10_config_lookup_from_file default; flag now errors)

Recommended action: Remove the v10_config_lookup_from_file flag from CLI/ESLINT_FLAGS/API; if you relied on cwd-based lookup pass --config path/to/eslint.config.js; delete eslint-env comments and declare globals via languageOptions.globals. Option: Adapt to v10 lookup and remove

Proposed fix: [SymPy parse_latex] 'LaTeX parsing requires the antlr4 Python package ... version 4.11' when omegaconf/hydra pins antlr4-python3-runtime 4.9 — math graders silently score 0

Recommended action: Detect it early: call sympy.parsing.latex.parse_latex('1') at startup and fail loudly. Keep math-grading in an environment without omegaconf 2.3/hydra 1.3 (or a separate venv/process), or use a latex parser backend that does not need antlr (sympy's lark backen

Proposed fix: [OpenAI Responses API] 400 "Unsupported value: 'minimal' is not supported with the 'o4-mini' model. Supported values are: 'low', 'medium', and 'high'."

Recommended action: Map efforts per model (o4-mini: low/medium/high only); don't reuse gpt-5 'minimal'/'none' settings across model families. Option: Clamp effort to the model's supported set [evidence: official_recommended_action] Steps: 1. Clamp effort to the model's supported

Proposed fix: [Anthropic Java SDK Bedrock/Vertex backends] AnthropicException 'Token counting is not supported for Bedrock.' / 'Batch API is not supported for Vertex.' / 'Service is not supported for

Recommended action: Keep token counting/batches/models on the first-party client (or use the cloud provider's native batch/count APIs); on Vertex use messages and count_tokens only. Option: Route unsupported operations elsewhere [evidence: documented_workaround] Steps: 1. use Ant

Proposed fix: [ESLint 9/10] 'ESLint couldn't find an eslint.config.* file' — .eslintrc/.eslintignore/package.json eslintConfig ignored; ESLINT_USE_FLAT_CONFIG=false escape hatch removed in v10

Recommended action: Migrate to eslint.config.js (the @eslint/v9-to-v10 codemod or the migration guide), move .eslintignore patterns into an 'ignores' config object, wrap legacy shareable configs with FlatCompat from @eslint/eslintrc; or pin eslint@8 temporarily. Option: Migrate t

Proposed fix: [GitHub App/OAuth web flow] 'redirect_uri_mismatch' / 'incorrect_client_credentials' / 'bad_verification_code' / 'unverified_user_email' when exchanging codes for user tokens

Recommended action: Register every callback URL the tool uses (exact scheme/host/port/path) or omit redirect_uri; re-copy client credentials from app settings; restart device flow for bad_verification_code; ask the user to verify their primary email. Evidence basis (self-declared

Proposed fix: [OpenAI Node Azure Realtime] 'Azure OpenAI Realtime credentials require a WebSocket transport that supports request headers' in browsers/native WebSocket

Recommended action: Use openai/realtime/ws (Node ws package) server-side, or put a server-side authentication proxy in front for browser clients (or use WebRTC with ephemeral tokens). Option: Use ws transport or proxy [evidence: official_recommended_action] Steps: 1. import { Ope

Proposed fix: [GitHub App user access tokens] Agent integrations break after 8 hours; refresh fails with 'bad_refresh_token' (refresh token invalid or expired after 6 months)

Recommended action: Persist and rotate both tokens on every refresh (store the new refresh token), refresh proactively before expires_in, and fall back to a new device/web flow on bad_refresh_token. Option: Rotate tokens atomically [evidence: official_recommended_action] Applies

Proposed fix: [TypeScript paths aliases at runtime] tsc compiles '@/lib/x' imports fine but Node crashes 'Cannot find package '@/lib' imported from ...' — paths does not rewrite emitted imports

Recommended action: Replace convenience aliases with package.json 'imports' (subpath imports, e.g. '#/*'; Node recently allowed '#/' prefix, supported by TS 6.0) or run through a bundler/loader that applies the same aliases. Libraries should not publish code depending on paths. O

Proposed fix: [Python subprocess shell=True on Windows] Agent bash-style commands run under cmd.exe: single quotes are passed literally (echo 'X' prints 'X' with quotes), breaking sentinel/marker pars

Recommended action: On Windows, run agent commands through an explicit bash (Git Bash/WSL) via args list (e.g. ['bash','-lc',cmd]) or a configurable shell; strip CRLF before matching markers; run CI on Windows if Windows is supported. Option: Invoke bash explicitly on

Proposed fix: [GitHub device flow] Token endpoint answers HTTP 200 with an error field while pending — clients that treat 2xx as success crash on a missing access_token

Recommended action: Parse the body on every poll: if it contains error, branch on its value; only proceed when access_token is present. Request JSON with Accept: application/json. Option: Check the error field, not the status [evidence: official_recommended_action] Applies when:
