A product manager's day is a sequence of artifacts: a PRD for the next quarter's bet, a sprint plan that survives contact with the team, an OKR check-in the exec staff actually reads, a competitive matrix when the rival ships, an A/B test design that is statistically honest, a clean Jira backlog, and a DX review of the API the team is about to commit to. None of it is technically hard. All of it is time-consuming, and the gap between the PM who runs a tight loop and the one who improvises is usually the gap between a roadmap that ships and one that slips. The seven skills below cover that surface area. Each is a real, verified Claude Code skill from a plugin with public commit history and real star counts.
From the myclaude plugin (2,670 stars). An interactive Product Owner skill for requirements gathering, analysis, and PRD generation. It runs an iterative dialogue with quality scoring before it writes the PRD, which is the difference between a one-page document that looks complete and a PRD that has actually pinned down state, errors, empty states, and edge cases. Triggers any time you ask for product requirements, a feature spec, or PRD creation. For a PM, the failure mode it prevents is the four-week build that turns into eight because the requirements were never fully written down.
When to use: the moment a roadmap item gets pulled forward into the next sprint, before any design or engineering kickoff, and as a forcing function over existing features you are about to extend. Run it before sprint-planner below so the sprint pulls from a real spec rather than a slack thread. Pair it with the Product Managers persona collection for the rest of the PM stack.
From the claude-skills plugin (13 stars). Runs agile sprints end-to-end: backlog refinement, story pointing, sprint planning, daily standups, and retrospective formats. The win for a PM is not that any one ceremony gets faster — it is that the artifacts from each ceremony feed into the next without manual re-entry, so the standup notes inform the retro, the retro informs the next refinement, and the loop stops dropping context every two weeks. The story-pointing prompt alone (planning poker scaffolding, reference stories, calibration against the last three sprints) is the part most teams skip and most velocity gaps trace back to.
When to use: the day before sprint planning, every morning for the standup template, and at the end of every sprint for a structured retro. Run it downstream of product-requirements so the backlog items being pointed have real specs. Pair it with the jira-helper skill below to push the planned sprint into Jira without copy-paste.
Also from claude-skills. Designs and tracks OKR frameworks: objectives, measurable key results, check-in templates, and scoring rubrics. The reason this matters is that most OKRs fail not on ambition but on instrumentation — the key result was never quantitative enough to track, the check-in cadence drifted from weekly to monthly to never, and by quarter-end the only honest score is "we did some work." The skill enforces measurability up front and gives you a check-in template that takes ten minutes a week instead of an hour, which is the difference between OKRs that survive past week three and ones that quietly die.
When to use: the first week of every quarter for objective setting, every Monday morning for the check-in, and mid-quarter when a key result is clearly off-track and needs to be re-scoped honestly rather than abandoned silently. Pair it with the data-analyst skill stack for the SQL and dashboard work that feeds the actual key-result numbers.
Also from claude-skills. Analyzes competitors with feature matrices, pricing comparisons, positioning maps, and SWOT analysis. The PM use case is the one that comes up at the worst possible moment: a competitor ships something, the CEO forwards the launch tweet at 9pm, and you need a real answer by the morning standup. The skill produces a feature matrix and a pricing comparison in the time it would take to open a new Notion page, and the positioning map gives you something more useful than "they did X, we should do X too" — it gives you the segment where the move actually pulls users away from you and the segment where it does not.
When to use: every time a direct competitor ships, once a quarter as a structured refresh of the full landscape, and before any pricing change or repositioning of your own. Run it before product-requirements when the response is going to be a real feature build, so the PRD opens with the competitive context already laid out. Pair it with the marketer skill stack when the response is positioning rather than product.
Also from claude-skills. Designs and analyzes A/B tests: sample sizes, significance testing, multiple comparisons, and results interpretation. This is the skill that prevents the two most common A/B test failures in product orgs — running a test that was never powered to detect a realistic effect (and then calling the null result a win for the control), and reading a noisy mid-experiment dashboard as if it were a final result. The sample-size calculator alone, run before the test goes live, will tell you whether the test is worth running at the current traffic — sometimes the honest answer is to ship the obvious better variant and skip the test.
When to use: before every experiment goes live (for the sample-size and power calculation), every time the team is tempted to peek at mid-experiment results, and at the end of every test for the multiple-comparisons-aware results writeup. Pair it with the okr-tracker skill above so test outcomes feed cleanly into the key-result the experiment was supposed to move.
Also from claude-skills. Automates Jira: issue creation, sprint management, JQL queries, and project reporting via REST API. For a PM, Jira is the tax — the place where good thinking goes to be retyped into nine separate tickets at 5pm on a Friday. The skill removes the retyping. Issues get created from the PRD, JQL queries replace the dashboards you keep meaning to build, and the weekly project report gets generated from the current ticket state instead of half-remembered. The combination of product-requirements writing the spec, sprint-planner shaping the sprint, and jira-helper pushing it into the tracker eliminates the longest manual step in a PM's week.
When to use: immediately after every PRD is signed off (bulk-create the issues from the spec), every Monday for the weekly project report, and any time a stakeholder asks a "how many tickets are open in X state" question (JQL beats clicking through filters). Pair it with the devops-engineer skill stack for the release-management half of the workflow.
From the gstack plugin (101,861 stars). An interactive developer-experience plan review. Explores developer personas, benchmarks against competitors, designs magical moments, and traces friction points before scoring. Three modes — DX EXPANSION (competitive advantage), DX POLISH (bulletproof every touchpoint), DX TRIAGE (critical gaps only). The reason this belongs on a PM list is that more and more PM work involves a developer-facing surface: a public API, an SDK, an internal platform, a CLI, a webhook integration. DX is the product for those surfaces, and the skill gives a structured way to review one before the engineering team commits to it.
When to use: any time the team is shipping a developer-facing surface (API, SDK, CLI, library, integration), before the public design is locked, and as a quarterly audit of existing developer touchpoints. Pair it with the backend-engineer skill stack for the implementation half of the same workflow, and with competitive-analyst above so the DX benchmark uses the same competitive frame as the rest of the product.
How to install
Each skill lives inside a plugin. Add the plugin marketplace once, then install with a single command — the skill detail page on Skill Index has the exact install string and a copy button. The highest-ROI sequence: start with myclaude/product-requirements so every roadmap item has a real spec, then add claude-skills/sprint-planner and claude-skills/jira-helper so the spec flows into a sprint and into the tracker without copy-paste, then layer in claude-skills/okr-tracker for the quarterly cadence and claude-skills/competitive-analyst for the moments a rival ships. Add claude-skills/ab-test-designer the first time an experiment is on the table, and reach for gstack/plan-devex-review whenever the surface is developer-facing. Pair the output with the rest of the thicket toolkit — screenshots for stakeholder updates via capture.thicket.sh, QR codes on launch-day pages via qr.thicket.sh, and deep-work blocks for the PRD writing itself via focus.thicket.sh — and being a PM stops being a Tetris game of artifacts and starts being a loop you can actually run.
