| description: Use sem to get entity-level (function/class/method) semantic diffs, impact analysis, blame, and dependency context from any Git repo. Trigger this skill whenever the user asks what changed in a commit or PR, wants to understand the blast radius of a change, needs to know who last modified a function, wants to trace how a function evolved, or needs structured code context for an LLM task. Also use it proactively when reviewing code, planning refactors, or any time line-level git diff output would be noisy or hard to interpret. | ||

| compatibility: Requires the sem CLI (https://github.com/Ataraxy-Labs/sem) on PATH and a Git repository |

- [low] CHANGELOG.md has duplicate '### Added' heading at lines 8 and 11, which will break markdown parsing and navigation. The second heading should likely be '### Changed' or '### Fixed'.

Rides the agent ecosystem , the cheapest way to turn agent users into sem users. ``` npx @ataraxy-labs/sem-skill ``` One command installs the sem **skill** into `~/.claude/skills/` and registers the **sem MCP server**, so a coding agent (Claude Code) picks up sem , impact / context / orient / diff over grep for structural questions , with no manual MCP wiring. Idempotent. - Distributes the **canonical skill from #376** (a `prepack` copies `skills/sem/SKILL.md`, single source of truth; credit to @linhlban150612). - The skill is extended with `sem orient` / `sem_entities` query and `sem context --hops` so it reflects current capabilities. Verified the installer end to end (skill installed, MCP detected, idempotent re-run). Not published to npm yet , that's a separate `npm publish` once you approve.
