Complete catalog of skills in this library. Slash commands are the usual entry points; skills also activate automatically based on task type. See README — Commands for the command list.
Claude Code uses /spec, /build, … Cursor uses /sys-spec, /sys-build, … (same workflows).
Skill
What It Does
Use When
syspm Mirrored SysPM PM skill with plan/structure/sync/track references
You want the PM lifecycle mirrored inside this repository
pm-spec-and-prd Creates PM-first PRDs and converts PRDs into epic artifacts
Starting PM planning from initiative scope before story-level engineering planning
pm-epic-decomposition Breaks an epic into T### Jira-mappable work items with dependency metadata
An epic exists and needs decomposed delivery units
pm-jira-sync Syncs SysPM epic and T### artifacts to Jira and maintains local mapping
Local SysPM artifacts should become Jira issues
pm-status-and-reporting Produces artifact-backed PM status updates from SysPM and Jira state
Stakeholders request progress, blockers, or next PM action
Discover — Understand the codebase
Skill
What It Does
Use When
brownfield-discovery Map an unfamiliar codebase — architecture, conventions, key files, and risk areas — before making changes
Joining a new project, onboarding to a legacy codebase, or scoping a change in unknown territory
Define — Clarify what to build
Skill
What It Does
Use When
idea-refine Structured divergent/convergent thinking to turn vague ideas into concrete proposals
You have a rough concept that needs exploration
spec-driven-development Write a PRD covering objectives, commands, structure, code style, testing, and boundaries before any code
Starting a new project, feature, or significant change
jira-spec-driven-development Jira-grounded spec workflow with mandatory Jira MCP validation, story context loading, and related-ticket context
Defining work directly from Jira tickets or stories
Skill
What It Does
Use When
planning-and-task-breakdown Decompose specs into small, verifiable tasks with acceptance criteria and dependency ordering
You have a spec and need implementable units
jira-planning-and-task-breakdown Story-scoped planning workflow that writes plan artifacts under jira-spec/{story-id}/
Planning implementation tasks for a Jira-scoped spec
Sync Jira board — After plan, before build
Skill
What It Does
Use When
jira-board-sync Writes jira-spec/{story-id}/sync.md comparing current Jira story/tasks to proposed updates from spec-* / plan-* / todo-*; applies to Jira only after explicit user approval
You need a reviewed diff before mutating the board
Skill
What It Does
Use When
incremental-implementation Thin vertical slices — implement, test, verify, commit. Feature flags, safe defaults, rollback-friendly changes
Any change touching more than one file
generate-unit-tests Generates unit tests from deferred test notes and implemented behavior
After build when coverage is missing or /test phase
context-engineering Feed agents the right information at the right time — rules files, context packing, MCP integrations
Starting a session, switching tasks, or when output quality drops
source-driven-development Ground every framework decision in official documentation — verify, cite sources, flag what's unverified
You want authoritative, source-cited code for any framework or library
frontend-ui-engineering Component architecture, design systems, state management, responsive design, WCAG 2.1 AA accessibility
Building or modifying user-facing interfaces
api-and-interface-design Contract-first design, Hyrum's Law, One-Version Rule, error semantics, boundary validation
Designing APIs, module boundaries, or public interfaces
mobile-app-engineering Production-quality mobile engineering for Android and iOS — architecture layers, screen states, error handling, UX discipline, platform safety
Building or modifying any mobile screen, flow, repository, service, or test
Skill
What It Does
Use When
browser-testing-with-devtools Chrome DevTools MCP for live runtime data — DOM inspection, console logs, network traces, performance profiling
Building or debugging anything that runs in a browser
debugging-and-error-recovery Five-step triage: reproduce, localize, reduce, fix, guard. Stop-the-line rule, safe fallbacks
Tests fail, builds break, or behavior is unexpected
Review — Quality gates before merge
Skill
What It Does
Use When
code-review-and-quality Five-axis review, change sizing (~100 lines), severity labels (Nit/Optional/FYI), review speed norms, splitting strategies
Before merging any change
code-simplification Chesterton's Fence, Rule of 500, reduce complexity while preserving exact behavior
Code works but is harder to read or maintain than it should be
security-and-hardening OWASP Top 10 prevention, auth patterns, secrets management, dependency auditing, three-tier boundary system
Handling user input, auth, data storage, or external integrations
performance-optimization Measure-first approach — Core Web Vitals targets, profiling workflows, bundle analysis, anti-pattern detection
Performance requirements exist or you suspect regressions
Ship — Deploy with confidence
Skill
What It Does
Use When
git-workflow-and-versioning Trunk-based development, atomic commits, change sizing (~100 lines), the commit-as-save-point pattern
Making any code change (always)
deprecation-and-migration Code-as-liability mindset, compulsory vs advisory deprecation, migration patterns, zombie code removal
Removing old systems, migrating users, or sunsetting features
