Skills catalog

Skills are Claude Code SKILL.md files synced into a project’s .claude/skills/. core skills apply everywhere; profile skills only reach projects with that profile enabled. Source lives at core/skills/<name>/SKILL.md or profiles/<profile>/skills/<name>/SKILL.md in the lacquer repo.

Every Source links somewhere: a skill’s own file in this repo (authored here, or with no further attributable external source), or the named upstream it was vendored from (copied in, then adapted to this repo’s conventions) — see Notes on vendored skills below each table for anything a short link can’t capture.

Skill Fires when Source
advisor-checkpoint Consulting a stronger model mid-task for a second opinion — stuck, before committing to an approach, or before declaring a non-trivial task done. advisor-checkpoint
antigravity-rescue Stuck, and wanting a second opinion from Google’s Antigravity CLI (agy) via a real subprocess — forwards the task and returns its output verbatim. antigravity-rescue
caveman User says “caveman mode”, “less tokens”, “be brief”, or invokes /caveman — token-efficient terse replies. caveman
claude-rescue Running under Codex CLI, stuck, and wanting a second opinion from Claude Code via a real subprocess — forwards the task and returns its output verbatim. openai/codex-plugin-cc (codex-rescue, reversed)
evaluator-optimizer Generate a solution, evaluate against explicit pass/fail criteria, refine, repeat until it passes or a round cap is hit. evaluator-optimizer
github-ci-fix PR checks fail, CI is red, or a GitHub Actions workflow breaks — inspects failing checks via gh, pulls logs, scopes external checks, builds a fix plan. github-ci-fix
github-issue-fix-flow Given a GitHub issue number: implement a fix, run builds/tests, commit with a closing message, push. github-issue-fix-flow
manager-loop Running a large batch of independent work items (fleet-wide harvest, multi-repo sync-down, overnight backlog) as a persistent coordinator. manager-loop
nameplate-attention Grabbing the human’s attention (topmost message card + pulsating screen borders) before a password-manager prompt or whenever blocked on them. steipete/nameplate
security-review Adversarial security review of a branch diff, PR, or working tree before merge. security-review
skill-authoring-standard Writing or reviewing a SKILL.md — the bar it must clear: tight trigger-oriented frontmatter, single responsibility, no padding. skill-authoring-standard

Several skills in this profile are vendored from public, per-topic “Agent Skill” repos by AvdLee (Antoine van der Lee — SwiftLee); others are original to this repo. See the notes below the table.

Skill Fires when Source

rocketsim Interacting with iOS Simulator apps via RocketSim — reading accessibility elements, tapping, swiping, typing, hardware buttons. AvdLee/RocketSim-Agent-Skill
swift-concurrency Diagnosing data races, converting callbacks to async/await, actor isolation, Sendable conformance, Swift 6 migration. AvdLee/Swift-Concurrency-Agent-Skill
swift-testing-expert Writing or modernizing Swift Testing suites — #expect/#require, traits/tags, parameterized tests, XCTest migration. AvdLee/Swift-Testing-Agent-Skill
swiftui-expert-skill Writing, reviewing, or improving SwiftUI code — state management, view composition, performance, Liquid Glass adoption; also analyzes Instruments .trace files. AvdLee/SwiftUI-Agent-Skill
swiftui-liquid-glass Adopting or reviewing the iOS 26+ Liquid Glass API in SwiftUI. split from AvdLee/SwiftUI-Agent-Skill’s reference material
swiftui-performance-audit Diagnosing slow rendering, janky scrolling, high CPU/memory, or excessive view updates in SwiftUI. split from AvdLee/SwiftUI-Agent-Skill’s reference material
swiftui-ui-patterns Creating or refactoring SwiftUI UI, tab architecture, screen composition. swiftui-ui-patterns
swiftui-view-refactor Cleaning up a SwiftUI view’s structure, dependency injection, and Observation usage. swiftui-view-refactor
update-swiftui-apis Scanning Apple’s SwiftUI docs for deprecated APIs and refreshing the swiftui-expert-skill with replacements (requires the Sosumi MCP). update-swiftui-apis
xcode-build-benchmark Benchmarking clean/incremental Xcode builds with repeatable inputs and timestamped artifacts. AvdLee/Xcode-Build-Optimization-Agent-Skill
xcode-build-fixer Applying an approved Xcode build optimization plan, then re-benchmarking. AvdLee/Xcode-Build-Optimization-Agent-Skill
xcode-build-orchestrator End-to-end build optimization: benchmark, run specialist analyzers, prioritize, get approval, delegate fixes, re-benchmark. AvdLee/Xcode-Build-Optimization-Agent-Skill
xcode-compilation-analyzer Analyzing Swift compile hotspots and type-checking cost from build timing summaries. AvdLee/Xcode-Build-Optimization-Agent-Skill
xcode-project-analyzer Auditing Xcode project config, build settings, schemes, and script phases for build-time improvements. AvdLee/Xcode-Build-Optimization-Agent-Skill
  • swift-concurrency is also based on Antoine van der Lee’s paid Swift Concurrency Course — the skill body itself only carries a plain-text attribution line, no link: commit a228d797 deliberately scrubbed swiftconcurrencycourse.com/UTM links from the synced skill to avoid shipping course marketing fleet-wide. That decision stands here too — see the git history rather than expecting a link inside the skill.
  • rocketsim also integrates with the third-party RocketSim app itself (paid, not bundled) — distinct from the skill’s own source above.
  • swiftui-liquid-glass additionally cites Apple’s WWDC25 session 323 for one design note.

Not this repo’s own skills — installed per-project via [project].skills in .lacquer.toml and lacquer skills (see the README for the mechanism). Listed here so the packages this fleet actually pulls in have a source link.

dpearson2699/swift-ios-skills — Apple-framework reference skills. lacquer init suggests these automatically from a component’s Swift imports (see internal/skillsuggest); this table is that same mapping.
