execute-spec

The skill outline demonstrates coherent purpose-capability alignment: it reads an ideation spec, creates and manages tasks, and orchestrates implementation with validations, including optional parallelism. Trust posture is reasonable since all actions operate within the local workspace and internal task APIs, with no evident external credential handling or downloads. Data flows stay within the workspace (specs, task metadata, code changes) and are consistent with the stated objective. The most notable risk is the autonomous subagent parallelism and complex task orchestration, which could increase blast radius if a malformed spec is provided; however, the design includes user prompts to select among multiple specs and a controlled progression model. Overall, the footprint is proportionate to the described purpose, with moderate to low security risk given the described constraints.
