# `phuryn/pm-skills` — Install-Alongside Guidance > Companion doc for the 2026-07-05 `phuryn/pm-skills` evaluation (Epic #750, > issue #761). Verdict: **crib the proven techniques, don't vendor the > marketplace.** The cribbed techniques already live natively in `/grill`, > `/brainstorm`, `/plan`, and the `/discovery` `feature` scope (see § Overlap > table below). This doc is for the narrower case where a *product* repo > wants the full `phuryn/pm-skills` roster installed side-by-side. ## When to install alongside `phuryn/pm-skills` (68-skill PM marketplace, MIT license, Claude-Code-shaped) is worth installing **in addition to** this plugin when a repo has a genuine, recurring PM-workflow need that produces standalone artifacts this plugin does not generate: - **Product-heavy repos** — Ventures-produkt-repos, client MVPs with an active PM/product-owner role — that run discovery interviews, maintain a roadmap document, or keep persona/Opportunity-Solution-Tree artifacts as living deliverables (not one-off planning inputs). - The team wants those artifacts as their own documents (roadmap.md, personas.md, OST diagrams) rather than folded into a PRD or an interrogation transcript. - Cursor-IDE parity is not a requirement for that repo — `phuryn/pm-skills` targets Claude-Code-shaped skills with no guarantee of cross-platform support. ## When NOT to install alongside - **Infrastructure / tooling repos** (this repo is the reference case). The evidence-based slice of PM discipline — assumption interrogation, divergent ideation, opportunity ranking, and evidence-anchored feature-intent findings — is already native here: - `/grill` — kill-assumption operationalization (Fails-if / Evidence-this-week / Kill-criterion / Cheapest-test) + pre-mortem Tiger/Paper-Tiger/Elephant taxonomy, part of the Six Tactics in `skills/grill/soul.md`. - `/brainstorm` — three-lens (PM / Designer / Engineer) divergent ideation pass plus Mom-Test interview discipline, in `skills/brainstorm/SKILL.md`. - `/plan` — Opportunity Score ranking, Impact×Risk 2×2 triage, and an optional job-story format, in `skills/plan/SKILL.md` / `mode-feature.md`. - `/discovery feature` — grounded, grep-verified intent-drift and stubbed/dead-feature probes (`skills/discovery/probes-feature.md`), routing judgment-based PM work (OST, personas, market-sizing) out to `/brainstorm`/`/plan` rather than treating it as a verified finding. - A second, un-integrated 68-skill roster would not participate in this plugin's session-config, quality gates, or `/discovery` verification pipeline (PSA-006) — see § Warnings below. ## How to install `phuryn/pm-skills` follows the same Claude Code plugin-marketplace mechanism this plugin itself ships through (see `README.md` § Install): ```text /plugin marketplace add phuryn/pm-skills /plugin install @phuryn ``` Consult the `phuryn/pm-skills` repository (github.com/phuryn/pm-skills) for the exact marketplace slug and the current skill roster — this doc does not duplicate that upstream README. Install only the specific skills a repo needs (roadmap, persona, OST artifact generation) rather than the full roster, to limit auto-dispatch noise (see § Warnings). ## Overlap / Abgrenzung | Capability | Overlap with this plugin | Where it lives | Verdict | |---|---|---|---| | Assumption interrogation / red-teaming a plan | `strategy-red-team`-class pm-skills ↔ `/grill` | `skills/grill/soul.md` (Six Tactics, kill-assumption workup, pre-mortem) | Overlap — prefer `/grill` (session/gate-integrated, codebase-grounded) | | Divergent ideation / brainstorming | `brainstorm-ideas-*`-class pm-skills ↔ `/brainstorm` | `skills/brainstorm/SKILL.md` (three-lens PM/Designer/Engineer pass, Mom-Test) | Overlap — prefer `/brainstorm` (HARD-GATE + PRD hand-off already wired) | | PRD generation / feature scoping / prioritization | `create-prd`-class pm-skills ↔ `/plan feature` | `skills/plan/SKILL.md`, `mode-feature.md` (Opportunity Score, 2×2 risk triage, job-story option) | Overlap — prefer `/plan` (researched Q&A engine, issue creation, appetite/scope discipline already wired) | | Documented-vs-enforced intent auditing | No pm-skills equivalent | `/discovery feature` (`skills/discovery/probes-feature.md`) | Unique to this plugin — grep-verified, not judgment-based | | Roadmap documents, stakeholder maps, persona trees as standalone artifacts | No equivalent here — this plugin folds personas/roadmap input into PRDs, not standalone living documents | `phuryn/pm-skills` | Unique to pm-skills — install alongside if a repo needs these as first-class artifacts | | Opportunity Solution Tree (OST) as a maintained document | No equivalent here (OST reasoning is routed out of `/discovery`'s verified pipeline per its Non-Goals) | `phuryn/pm-skills` | Unique to pm-skills | | Market-sizing / competitive-landscape docs | No equivalent here | `phuryn/pm-skills` | Unique to pm-skills | Rule of thumb: where a technique overlaps, this plugin's version wins because it is wired into session lifecycle, quality gates, and issue creation. Where the artifact is a standalone PM document this plugin was never designed to produce, `phuryn/pm-skills` fills a real gap — install it alongside for those repos only. ## Warnings - **Roster size → auto-dispatch noise.** Installing the full 68-skill roster alongside this plugin's own skill catalog increases the surface `auto-skill-dispatch` phrase-matching has to disambiguate against. Prefer installing only the specific skills a repo actually uses. - **Claude Code only.** `phuryn/pm-skills` is Claude-Code-shaped with no Cursor IDE (or Codex CLI / Pi) parity guarantee. This plugin maintains cross-platform support (see `README.md` § Install) — a repo that also runs Cursor sessions loses parity the moment it depends on a pm-skills-only workflow. - **No session-config or gate integration.** pm-skills artifacts do not participate in this plugin's Session Config, quality gates, or `/discovery` PSA-006 verification discipline. Treat its output as an independent artifact stream, not something `/close` or the wave-executor will track. - **Sunset risk.** An installed-but-rarely-used skill from the roster is a `sunset-review` candidate within a session or two — install narrowly, or expect churn. ## See Also - `README.md` § Install — the plugin-marketplace install mechanism this doc reuses. - `skills/grill/soul.md`, `skills/brainstorm/SKILL.md`, `skills/plan/SKILL.md` — the native crib targets (Six Tactics, three-lens ideation, Opportunity Score/2×2/job-story). - `skills/discovery/probes-feature.md` — the grep-verified intent-drift and stubbed-dead-feature probes that keep evidence-based PM findings inside the verified pipeline. - Epic #750 / issue #761 — the evaluation and companion-doc tracking issue this document closes.
