Give Claude Code GPU access via Google Colab
Five tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. All tools have descriptions (10-50 chars, below the 50-200 char baseline for LLM optimization). Input schemas present but parameters lack detailed constraints and format guidance. No output schemas documented. Error handling returns raw strings rather than structured recovery guidance. Tool names follow verb_noun pattern (colab_status, colab_exec, colab_python, colab_upload, colab_download) which is good, but descriptions are terse and lack WHEN/WHY context. Parameters like 'timeout' and 'command' have minimal descriptions. No enum constraints, no range validation hints, no idempotency markers.
Download a file from the Colab GPU instance to local disk
Run a shell command on the Colab GPU instance
Execute Python code on the Colab GPU instance
Get Colab GPU status: name, VRAM, disk, uptime
Upload a local file to the Colab GPU instance
Output schemas not documented. Tools return Union[dict, str] with no specification of dict structure, field names, or types. LLMs cannot plan downstream calls or extract required data.
Descriptions are terse (10-50 chars, below 50-200 char baseline). Missing WHEN/WHY context. E.g., 'Get Colab GPU status: name, VRAM, disk, uptime' lacks guidance on when to call vs other tools or what to do with the result.
Parameter descriptions lack format/constraint guidance. 'timeout' has no min/max bounds (code shows max 600 but description doesn't state this). 'command' and 'code' lack examples of valid input or error cases.

Error handling returns raw strings ('Not connected...', ColabError str) instead of structured recovery guidance. LLMs cannot parse error type or determine if retry is safe.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint). colab_exec and colab_python are destructive (modify state) but lack markers. colab_status and colab_download are read-only but unmarked.
