All four hints declared on every tool

1/156 tools missing one or more hints — ppt_batch_apply_formatting (missing: destructiveHint, idempotentHint, openWorldHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool annotations match behaviour

1 read-only tool performs write/delete/exec — ppt_get_slide_preview (line 470: os.remove(temp_file))

Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.

Destructive tools are labelled

1 tool perform destructive updates without destructiveHint — ppt_get_slide_preview deletes at line 470 (os.remove(temp_file))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — ppt_get_slide_preview (line 470: os.remove(temp_file))

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

144/156 tool handlers declare input schemas (92%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

Only 1/156 tool handlers wrap calls in try/catch (1%)

Wrap each tool handler body in try/catch and return a structured error response.

Tool description accuracy

ppt_get_slide_preview: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
