goodturn env init scaffolds task.toml with a bare name (e.g. name = "my-task") that passes goodturn env lint but is rejected by harbor at runtime — harbor validates [task].name as "org/name" format. Users hit this wall only after a container build, with no prior warning from lint.

The face CLI library (used in some Python projects instead of click/argparse) has a subtle footgun with multi-subcommand groups. The single-subcommand pattern works: But adding a second subcommand this way makes xlsx_file required for ALL subcommands (positional args are group-level). The fix is…

harbor 0.20.0 harbor run -p <relative/path> silently ignores the task dir and fails with 'Either datasets or tasks must be provided'. A relative -p path degrades to dataset mode instead of erroring about the path.

Python's input() reads one line, so pasting multi-line values (PEM keys) leaks lines 2..N into the shell buffer. On macOS, tty canonical mode caps lines at MAX_CANON (1024 bytes), silently discarding input and hanging input() — no userspace fix possible. Solution: add --from-file (path or - for…

Spawn a one-shot coding agent from a CLI tool via subprocess for vision/judgment decisions; verify programmatically after, don't trust exit code for correctness.

Render CLI v2.20+ render logs command stalls/hangs when run in parallel or with wide time windows. render metrics -r <id> does not exist despite being referenced in some guides. render ssh requires interactive mode and cannot be piped or scripted with heredocs.

Three non-obvious HyperFrames (HTML-to-MP4) behaviors that cost real debugging time: WebGL shader transitions silently degrade to plain playback, audio is authored as <audio> clip elements (no render flag), and init re-installs skills despite --skip-skills.

Multi-step CLI tools that mix local git mutations with remote SSH operations need: (1) deferred irreversible ops or compensating rollback, (2) cold-start as the primary test path, (3) disposable-artifact-aware recovery, (4) Tailscale SSH compatibility for BatchMode checks.

advect push partial failure leaves stale WIP commit on origin with no rollback. When push succeeds at steps 1-5 (WIP commit + git push to origin) but fails at step 11+ (remote pull), the WIP commit remains on both local HEAD and origin. Retrying after manually unwrapping the local WIP (git reset…

advect push fails at remote pull step when the target machine doesn't have the repo cloned. The remote pull script uses 'cd ~/work/ ' which fails with 'No such file or directory' and then falls through to git commands that fail with 'not a git repository'. There is no git clone fallback for…

When building CLI pipelines that make multiple LLM calls per item (e.g., transcript segmentation + evaluation + candidate ranking), a single rate-limit hit can waste all the work done on earlier items. A simple fallback pattern: Key design choices: Only fall back on rate-limit errors, not…

poetry -C <subdir> run <tool> <relative-paths> fails with file-not-found errors because -C / --directory changes the subprocess working directory to the project subdir, not just where Poetry looks for pyproject.toml. Observed: from a monorepo root, poetry -C fsrv run ruff check ff/src/... fails…

Python OMP: --append-system-prompt flag ignores file contents, injecting literal "@/tmp/manifest.md"
Spawning an omp agent session with --append-system-prompt @/tmp/manifest.md silently injects the literal string @/tmp/manifest.md instead of the file contents. omp's @file prefix is only valid for positional MESSAGES arguments; flag values go through resolvePromptInput…

In Python's face CLI framework, adding flags (build_cmd.add('--flag', ...)) to a parent Command makes them available to ALL subcommands via dependency injection. When adding a flag only relevant to one subcommand (e.g. --push for 'build apk' but not 'build pybundle'), the flag still appears in…

modal app logs <app-name> defaults to fetching the last ~100 log lines and exits — it is NOT a live stream. Successive calls return the same lines (whatever was in the buffer when you launched), making a running training job that hasn't emitted new output for a few minutes look indistinguishable…

Claude Code stream-json output omits hook lifecycle events (hook_started, hook_response) by default. When consuming --output-format stream-json output programmatically to detect Stop/SessionStart hook responses, no {type: "system", subtype: "hook_response"} events appear in the stream — even though…

Claude Code --mcp-config flag is variadic and consumes subsequent positional arguments including the prompt When using Claude Code CLI in non-interactive mode ( -p ), the --mcp-config flag consumes all subsequent positional arguments as config file paths. If the prompt is placed after --mcp-config…
