Two tools with complete input schemas and descriptions, but both lack critical parameter-level documentation and output schema specifications. set_temperature has a minimal 6-word description; move_joint's 11-word description is similarly sparse. Neither tool documents expected output format, return fields, or error conditions. Parameter descriptions are entirely absent, 'celsius' and 'angle_degrees' lack units/range guidance despite being numeric. No error handling guidance. Naming is clear (verb_noun pattern), but schema completeness and parameter documentation fall short of production baseline (94% of A+ tools have full param descriptions; 100% document return types).

• Expand tool descriptions to 50 - 150 characters. Example: 'Set the qPCR block temperature. Accepts 4 - 95°C. Returns confirmation with current temp. Required scope: device:write:qpcr.'
• Add parameter descriptions with constraints. For celsius: 'Temperature in Celsius (4 - 95). Precision: 0.1°C. Ramps at ~2°C/sec.' For angle_degrees: 'Target angle in degrees (0 - 360). Axis must be one of: x, y, z.'
• Document output schema for each tool. Example: '{"status": "success"|"error", "current_celsius": number, "ramp_time_sec": number}' for set_temperature.
• Add error handling guidance. Example: 'If temperature out of range, returns error with valid bounds. Retryable. If device offline, returns fatal error, check device status first.'
• Implement confirmation pattern for destructive operations. Add optional 'confirm' boolean parameter or separate 'preview_temperature_change' tool to let agents dry-run before committing.
