Automation vs Testing · both proven

triage vs writing-guidelines

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

triage

Move issues and external PRs through a state machine of triage roles, categorise, verify, grill if needed, and write agent-ready briefs.

Brief: “You are triaging three new issues on an open-source Markdown editor. #412 "App crashes" by @kmorr: "It crashes when I paste stuff. Please fix asap." #413 "Export to PDF loses images" by @dlee: "On v2.3.1 (macOS 15), exporting a note with two PNG images to PDF produces a PDF with blank boxes where the images were. Steps: create note, drag in two PNGs, File > Export > PDF. Expected images in the PDF. Worked in v2.2.0." #414 "Add vim keybindings" by @tpz: "Would love vim mode. Lots of editors have it." Present the triage as a single HTML page: for each issue, the category, the state you would move it to and why, the comment you would post, and for any issue ready for an agent to implement, the agent brief.”

Brief: “Review and rewrite this getting-started page for Pipewell, a data pipeline CLI. The draft opens with two paragraphs of company history, mixes 'you' and 'the user', buries the install command in the fourth paragraph, uses passive voice throughout, and ends without a next step. Write the improved page as a single HTML document, followed by a short list of what you changed and why.”
