Why it mattersA skill saves a team from writing a long prompt every time. A ready pack gives a new Claude Code user working tools on day one.
A new skills pack for Claude Code is getting attention this week. The repository is dotslashsimran/simcraft. It has 412 stars and 32 forks on GitHub, under the MIT license. The author is Simran Sachdeva, and the project was created on 5 November.
Claude Code reads a folder of skills from a known place on disk. Each skill is a small file that tells Claude how to do one task. Simcraft is a pack of 24 such skills. They are grouped into five jobs. A team links the folder into that place to turn them on.
What the pack covers
The 24 skills sit in five categories. Video has eight: perspective-illusion, code-loop, reverse-engineer-video, scripted-screencast, repo-timelapse, rough-cut, clean-audio, and vox-explainer. Engineering has seven: codebase-map, bisect-anything, flaky-test-killer, benchmark-honestly, api-design-review, security-threat-model, and dx-audit. Learning has four: paper-to-runnable, system-design-from-scratch, from-scratch, and teach-back. Design has two: image-gen and brand-kit. Planning has three: skill-router, next-step, and video-script.
Each skill carries a one-line job. codebase-map reads an unfamiliar repository by following one real request end to end. paper-to-runnable turns a research paper into the smallest honest version of its idea. teach-back has the user explain something, then has Claude find the gaps and write a one-page cheat sheet. flaky-test-killer fixes the real cause of a flaky test, never with retries, and proves the fix.
Other skills address common jobs. benchmark-honestly runs a benchmark and reports it with confidence intervals. dx-audit tries a developer tool as a brand-new user would, and times how long first success takes. api-design-review reads an API, SDK or CLI and catches breaking changes. skill-router picks the right skill for a task, or a chain of two or three skills in order.
What makes the pack different
Sachdeva writes that the skills are "built from real projects, with the parts tutorials skip". The repository's README states what makes them different: every skill covers "what breaks, how to check the result, and how to tell good from good enough". A skill teaches the model both the step and how to notice its own failure on that step.
The author's tagline reads: "Skills that teach Claude how to do hard things well."
A Claude Code user can clone the repository on their own machine. They then link any skill folder into their skills directory. Claude Code picks up the skill the next time a matching request appears. The license is MIT, so a team can copy a skill, change it, and keep the copy private.
