A portable Agent Skill for SIFT — Structural Inspection for Technical Simplification: a complete, read-only codebase audit focused on material simplifications in data structures, state representation, algorithms, control flow, schemas, lifecycle/concurrency, and ownership.
The skill creates a coverage contract, partitions the repository into non-overlapping subsystem reviews, validates every finding, rejects abstraction churn, audits its own coverage, and returns a prioritized implementation plan. It does not edit the repository or run tests; its only write is the final report artifact, docs/sift-audit-<date>.md by default.
npx skills add 2389-research/siftThis installs the skill project-local for the agents it detects. Add -g for a user-wide install.
Clone and copy. The installed directory must be named sift-codebase-audit to match the skill's name field:
git clone https://github.com/2389-research/sift.git
cp -R sift ~/.claude/skills/sift-codebase-audit/sift-codebase-audit
Or ask naturally:
Run SIFT on the complete repository. Exclude vendored dependencies and generated output.
The skill defaults to the current repository and whole-application coverage unless the request states a narrower scope.
