Four tools with explicit schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. list_notes and add_note have reasonable input schemas with descriptions; boom and blob are minimal. No output schemas visible in the source. Parameter descriptions exist but are sparse (e.g., 'how many bytes to return' lacks constraints). Tool names follow verb_noun convention (list_, add_, boom, blob) but 'boom' and 'blob' are vague and don't clearly signal intent. Error handling for boom is mentioned but not detailed. Overall: functional but below production baseline.

• Add outputSchema to all four tools. For list_notes, document the structure of the notes array and total field. For add_note, document the created note object. For boom and blob, document error and payload structures respectively.
• Rename 'boom' to 'trigger_error' and 'blob' to 'generate_payload' to make intent explicit. Update descriptions to explain these are test/fixture tools.
• Add min/max constraints to blob's 'bytes' parameter (e.g., 1 - 10485760) and document in the description: 'Number of bytes to generate (1 to 10 MB).'
• Clarify add_note's 'count' parameter: is it the number of copies to create, or something else? Add a description like 'Number of copies to create (1 - 100)' or remove if unused.
• Rewrite list_notes description from 'List notes, newest first.' to 'Retrieve all notes sorted by creation date (newest first). Use this to discover available notes before operating on them. Supports filtering by tag and limiting results.'
