The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: Fetches current manufacturing guides and engineering specifications directly from cdn.sendcutsend.com. These references are used as the ground truth for manufacturing readiness reports.
[COMMAND_EXECUTION]: Executes Python code using the build123d and ezdxf libraries to perform local geometry inspections, such as measuring part dimensions, hole sizes, and flange depths from user-provided CAD files.
[INDIRECT_PROMPT_INJECTION]: The skill ingests untrusted data from both user-uploaded CAD files (DXF/STEP) and external web sources (JSON/Markdown from SendCutSend).
Ingestion points: CAD files (DXF/STEP) in SKILL.md and remote configuration files defined in references/official-sources.md.
Boundary markers: Instructions specify that source data should be treated as "evidence feeds" rather than executable logic, and the agent is cautioned to handle missing or conflicting data without assuming success.
Capability inventory: The skill uses Python for geometric analysis and generates reports based on comparisons.
Sanitization: The skill mandates defensive parsing (e.g., handling numeric strings, size strings, and N/A values) to ensure data integrity during comparison.
