Included Skills9

implement-workskills/implement-work/SKILL.md

Use to take one PR-sized task — a sub-issue, an issue that fits a single PR, or a request of that size — all the way to a pushed branch of verified commits. Triggers on "implement this sub-issue", "start implementing", "work through this task", "run the completion gate", "take this to a branch".

investigate-anomalyskills/investigate-anomaly/SKILL.md

Use when root-causing an observed anomaly — production errors, an outage, a crashed job, an error-rate spike, unexplained cost or resource growth, or a metric drifting the wrong way — before any fix is proposed. Produces a blameless findings report, not a fix. Triggers on "why did this break", "root-cause this incident", "errors spiked", "costs keep growing", "this metric looks wrong", "what happened last night", "write the postmortem".

investigate-performanceskills/investigate-performance/SKILL.md

Use when diagnosing an observed performance shortfall — a slow endpoint, job, or query, a latency/throughput regression, or CPU/memory growth — to root-cause it with measurements before any fix is proposed. Produces a findings report, not a fix. Triggers on "why is this slow", "latency spiked", "perf regression", "high CPU", "memory keeps growing", "find the bottleneck".

plan-workskills/plan-work/SKILL.md

Use to turn an issue, a planning request, or an investigation's findings into an agreed design and a numbered TODO list at PR granularity, before any code is touched. Triggers on "plan this", "plan issue <n>", "turn this into a plan", "break this into PRs", "brainstorm and plan this".

pr-to-readyskills/pr-to-ready/SKILL.md

Use to take a branch of verified commits — with or without a PR on it yet — to a PR whose CI passes and whose review is clean, left at ready or draft. Triggers on "implementation is done, take it to a PR", "open the draft PR and drive it", "what next after opening the PR", "CI is failing", "run the review loop", "take it out of draft", "handle the review feedback".

review-codeskills/review-code/SKILL.md

Use to review code and fix what the review finds — on a diff, a branch, or an uncommitted working tree — leaving no blocking finding unresolved. Triggers on "review this code", "review and fix this", "run the review loop until it's clean".

review-planskills/review-plan/SKILL.md

Use to review planning work itself, before implementation starts or on a revision — either a TODO list breaking work into PR-sized items, or the detailed implementation plan for one PR. Reports findings; it never edits what it reviewed. Triggers on "review this plan", "review the TODO list", "is this plan ready to implement".

simplify-codeskills/simplify-code/SKILL.md

Use after implementation and before code review or PR creation to simplify recently modified code while preserving behavior. Triggers on "simplify this", "clean up the diff", "run a code-simplifier pass", "tidy this up before review".

using-dudeskills/using-dude/SKILL.md

Use when starting any task - establishes how a task is classified, which flow it enters, what each flow hands over, when a phase is clean, and where a loop stops.
