26 tools with mixed quality. Naming is consistent (verb_noun pattern: gdrive_*, sheets_*) and clear. Descriptions present but generic, most are 30-80 chars, below the 194-char baseline for A+ tools. Parameter descriptions exist but lack constraints (enums, ranges, formats). No output schemas documented. Error handling absent from visible code. Security concern: OAuth credentials handled in CallbackServer but no evidence of secret injection pattern in tool parameters. Composition is reasonable (separate auth, files, permissions, sheets modules), but tools lack idempotency markers and confirmation patterns for destructive ops.

No output schemas documented. LLMs cannot infer what fields to expect from tool responses, forcing them to guess at downstream field names and breaking tool chaining.
Parameter descriptions lack constraints. 'limit' appears in 5+ tools with no min/max bounds; 'role' in gdrive_share_file has no enum (reader|writer|owner); 'range' in sheets tools has no format hint (A1 notation). LLMs will pass invalid values.
Destructive operations (gdrive_remove_permission, sheets_clear_range, gdrive_move_file) lack confirmation or dry-run patterns. Agents can irreversibly delete data without safeguards.

Tool descriptions are generic and short (30-80 chars vs 194-char baseline). 'Create a new file in Google Drive' does not explain when to use it vs gdrive_create_folder, what mimeType values are valid, or what the response contains.
No error handling guidance visible. Tools do not document what errors are retryable, what user-fixable errors look like, or how to recover from auth failures or quota limits.
