blueprint-derive-plans

This skill's stated purpose (derive PRDs/ADRs/PRPs from git history and repo files) aligns with its capabilities: it reads git history and local documentation, analyzes commits, and writes generated documents back to the repository. There are no remote network calls, download-execute chains, or embedded obfuscated payloads in the provided code. The primary risks are operational: (1) the skill executes shell commands and writes files, so unsanitized inputs or unattended runs could lead to command-injection or undesirable repository modifications; (2) ability to invoke other tasks (/blueprint:init) expands the trust surface (transitive execution); and (3) since it can read repository files, it could surface any secrets already present in the repo into generated artifacts. These risks are consistent with a powerful automation skill and are mitigatable by requiring user confirmation before writes/Task invocations, sanitizing arguments, and performing a pre-flight diff of generated changes. Overall I find no evidence of intentional malicious behavior in the provided code, but the skill should be used with standard caution (review diffs, avoid running on repos with secrets) because it has broad local read/write and shell execution privileges.
