updated the product-management skills

[graemerycyk]

Summary

Expands the product-management plugin from 6 commands and 6 skills to 14 commands and 11 skills, covering the full PM lifecycle — from morning standup to sprint review, from raw idea to customer-facing release notes.

These additions come from OpenPMKit, an open-source PM toolkit. Only workflows with no existing overlap were added — the 5 that duplicated existing commands (write-spec, roadmap-update, competitive-brief, synthesize-research, stakeholder-update) were intentionally excluded, with their unique elements folded into the existing skills instead.

What's new

8 new commands

Command	What It Does
/daily-brief	Synthesize overnight activity into a morning brief
/meeting-prep	Prepare for customer meetings with context and talking points
/sprint-review	Generate a sprint review summary with metrics and demos
/prototype	Generate an interactive HTML prototype from a PRD or feature description
/release-notes	Create customer-facing release notes from completed work
/feature-ideation	Structure raw ideas into validated feature concepts
/one-pager	Synthesize complex information into a one-page executive summary
/tldr	Create a quick 3-5 bullet summary for Slack or email

5 new skills

Skill	What It Covers
sprint-execution	Sprint metrics, velocity analysis, demo preparation, burndown interpretation, retrospectives
meeting-preparation	Account review methodology, talking point frameworks, risk identification, QBR planning
release-communication	Customer-facing writing, changelog categorization, version conventions, deprecation lifecycle
executive-synthesis	Pyramid principle, one-pager framework, TL;DR writing, audience adaptation
html-prototyping	Design defaults, responsive layout patterns, interactive components, accessibility basics

2 existing skills updated

• feature-spec — Added "Idea Structuring" section: from raw idea to PRD-ready concept, 6-step structuring process, readiness criteria
• roadmap-management — Added "Decision Memos" section: when to write one, structure (options, evidence, trade-offs, recommendation), tips

README updated

• Commands table: 6 → 14
• Skills table: 6 → 11
• "What It Does" section: 6 → 13 bullet points
• 3 new example workflows (sprint review, morning brief, interactive prototype)

What's NOT changed

• .claude-plugin/plugin.json — no manifest changes
• CONNECTORS.md — existing connector categories already cover all new command needs
• .mcp.json — no new MCP connections needed
• LICENSE — unchanged
• All 6 existing commands — untouched
• All 6 existing skills — only 2 received additive updates (no existing content was modified or removed)

Design decisions

• No overlap: Analyzed all existing commands and skills before adding anything. The 5 overlapping OpenPMKit workflows were skipped entirely — their unique aspects were absorbed into existing skills as new sections.
• Consistent style: All new commands follow the existing pattern — YAML frontmatter, connectors banner, numbered workflow steps, ~~category tool references with graceful fallback, skill cross-references, Follow Up section, Tips section.
• Skill depth: Each new skill is 8-13K characters with frameworks, practical examples, anti-patterns, and checklists — matching the depth of existing skills like competitive-analysis and feature-spec.
• Commands reference skills: New commands cross-reference their corresponding skills (e.g., /sprint-review references the sprint-execution skill) so domain knowledge stays in one place.
