| # Claude Code Skills Pack |
|
|
| **18 production-grade skills for Claude Code. 5 free.** |
|
|
| Each skill is a `SKILL.md` that Claude Code loads automatically when you hit |
| the situation it covers — and then follows as an operating procedure, not a |
| suggestion. Rollout percentages for flag-gated releases. The exact loop for |
| killing a flaky test. The backwards-compatibility checklist for API changes. |
| The triage ladder for a pile of security findings. Written by someone who has |
| done these things at 3am, for the agent that has to do them next. |
|
|
| ## What's in the pack |
|
|
| | Skill | What it does | |
| |-------|--------------| |
| | `shipping-behind-feature-flags` | Rollout schedule with exact percentages and dwell times, written error-rate thresholds, and a rollback that's a 60-second flag flip. | |
| | `postmortem-writing` | Blameless format with a sourced timeline, root-cause discipline past "bug in X," and a 5-rule action-item rubric that rejects "improve monitoring." | |
| | `dependency-upgrade-triage` | A T1–T5 severity ladder (exploitable+reachable first), what to pin vs. skip vs. defer, and suppressions that require an owner and a review date. | |
| | `git-rebase-survival-guide` | Pre-flight checks, the conflict loop with test-after-every-continue, reflog recovery for bad force-pushes, and the rebase-vs-merge decision. | |
| | `perf-profiling-loop` | Measure→hypothesize→profile→fix loop, flamegraph reading heuristics, per-stack profiling commands. | |
| | `test-pyramid-refactor` | What to cut from an inverted suite, the bug-reintroduction check that makes cutting safe, and the time budgets per layer. | |
| | `api-contract-review` | The additive/risky/breaking classification, the deprecation-window rules, and the `oasdiff`/`buf breaking` CI gate. | |
| | `incident-runbook-authoring` | Runbook structure built for the tired 3am reader, the 5-minute triage rule, and the quarterly drill that keeps runbooks honest. | |
| | `code-review-discipline` | The B/M/m/nit severity rubric, the three-pass review structure, and the letting-go rules that keep PRs shipping Thursday. | |
| | `mcp-server-authoring` | Tool-schema design rules (one tool = one intent, enums over open-ended params), output byte-budgets, and the 5-prompt smoke test. | |
| | `claude-md-wrangling` | What belongs in CLAUDE.md and what doesn't, the 150-line budget, subdirectory splitting, and the fresh-session verification loop. | |
| | `flaky-test-hunting` | The N-run reproduction loop, the closed classification set (timer/order/state/race/network/locale), and the 200-run exit criteria. | |
| | `migration-rollback-plan` | Expand→migrate→contract sequencing, chunked idempotent backfills with lock-avoidance settings, and the rollback table written *before* anything runs. | |
| | `security-scan-triage` | Reachability-ranked severity (exploitability before CVSS), the source-to-sink check for SAST, and suppression entries with owners and dates. | |
| | `observability-instrumentation` | SLO-first instrumentation, 14.4×/6× burn-rate alerts, RED/USE metrics, and the cardinality trap that breaks TSDBs. | |
| | `release-notes-crafting` | Commit-to-user-sentence translation, the three-part breaking-change form, and audience altitude per reader. | |
| | `docs-drift-audit` | Executing documented commands in a clean clone, verifying defaults against source, and doc-tests that make drift a CI failure. | |
| | `ai-agent-eval-design` | Golden-set construction from production failures, anchored rubrics, LLM-judge bias controls, and the calibration bar (κ ≥ 0.6) before you trust a score. | |
|
|
| ## Free (5) |
|
|
| `flaky-test-hunting`, `code-review-discipline`, `postmortem-writing`, |
| `dependency-upgrade-triage`, `claude-md-wrangling` — the five highest-traffic |
| skills, included in the zip under `skills-pack/lite/` as a lead magnet. |
|
|
| ## Install |
|
|
| Download `skills-pack.zip` from this repository, unzip, then copy the |
| `skills/` directory into your Claude Code skills location: |
|
|
| ```bash |
| # Global (all projects) |
| cp -r skills ~/.claude/skills/ |
| |
| # Project-scoped (this repo only) |
| cp -r skills .claude/skills/ |
| ``` |
|
|
| Each skill activates automatically when your task matches its trigger — say |
| "this test is flaky, find out why" and `flaky-test-hunting` loads. You can |
| also invoke explicitly: "use the postmortem-writing skill." |
|
|
| ## License |
|
|
| Personal, non-commercial. Use in unlimited personal and work projects. Don't |
| resell the pack (or a substantially modified version of it) as-is. You may |
| use the skills' output (your rollouts, postmortems, runbooks) however you |
| like — those are yours. |
