thananon/9arm-skills

This repository is a personal collection of agent skills written for Claude Code, which is the command line coding assistant from Anthropic. A skill in this setting is a small folder that tells the assistant how to perform a specific kind of task. Each skill has a file called SKILL.md with a short header that names it and describes when it should be used, and the assistant pulls the skill in automatically when the situation matches. The README says the skills live in a folder named skills and are sorted into buckets. The engineering bucket holds daily code work, productivity holds daily non-code workflow tools, misc holds things that are kept around but rarely used, personal holds entries tied to the author's own setup that are not promoted, in-progress holds drafts that are not yet ready to ship, and deprecated holds skills no longer in use. Installation is simple. There is a shell script called link-skills.sh that creates symbolic links from every shippable skill into the user's ~/.claude/skills/ folder, which is where Claude Code looks for them. A second script called list-skills.sh prints every SKILL.md file in the repository so the author can see what is available. The README lists the skills that are currently ready. Under engineering there are three. The debug-mantra skill enforces a four-step debugging routine that reproduces the bug, traces the failure path, tries to falsify the working hypothesis, and cross-references every breadcrumb before any fix is attempted. The post-mortem skill writes a structured engineering record of a fixed bug, and it refuses to draft one unless there is a reliable reproduction, a known cause, and a validated fix. The scrutinize skill performs an outsider-style end-to-end review of a plan or pull request, asking whether the change does what it claims and whether there is a simpler way. Under productivity there is one skill. The management-talk skill rewrites engineer-to-engineer content for an engineering management audience, and it adjusts the wording for the specific channel, such as a JIRA ticket, a Slack message, an async standup, an email, or a set of meeting talking points. The misc bucket is empty for now.
