Skills worth trusting.
Agent skills from Anthropic, OpenAI, skills.sh, ClawHub, SkillsMP and other reputable sources. Savant assesses them for security risks and evaluates model-generated test cases using independent scoring. Workspaces import any skill into their own repositories through a reviewed pull request. Every listing on each hub is enumerated; packages are fetched, scanned and evaluated most-popular first as daily capacity allows.
api-rate-limiting
Implement API rate limiting strategies using token bucket, sliding window, and fixed window algorithms. Use when protecting APIs from abuse, managing traffic, or implementing tiered rate limits.
turborepo
Turborepo monorepo build system guidance. Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.
cook
Implement an approved spec or focused task through stale-safe source edits. Use this skill when the user says "implement this", "cook this spec", or "fix this bug". Use it for `/cook .cheese/specs/<slug>.md`. Also use it when the user says "go" with clear acceptance criteria. Run it alone for an unambiguous task. Use `--prototype` when the user says "prototype this", "go prototype it", or "spike this out" and wants to refine the result round by round. A spec helps but is not required. Do not use it for fuzzy planning (`/mold`). Do not use it for no-write discussion (`/culture`) or review-only work (`/age`).
refactor
Code refactoring best practices based on Martin Fowler's catalog and Clean Code principles (formerly refactoring). This skill should be used when refactoring existing code, improving code structure, reducing complexity, eliminating code smells, or reviewing code for maintainability. Triggers on tasks involving extract method, rename, decompose conditional, reduce coupling, or improve readability.

reg-gap-analysis
Diff a new or changed regulation against current privacy policy and practice — outputs a gap list and a remediation plan with owners and dates. Use when a new reg drops, the user asks "does [regulation] affect us", "gap analysis for [state privacy law]", "compliance check against [reg]", or pastes regulatory text.
source-part-segmentation
Segment overlapping visual parts from source images, wireframes, texture atlases, and decals before mesh reconstruction. Use when a mascot/logo/template contains touching or overlapping components and exact structural part masks are needed before contour-to-mesh, UV fitting, or landmark repair.

Covers series configuration, axis customization, markers, data labels, legend, tooltip, print/export, and accessibility features.
asb-rude-qa
Interrogates a user's decision, plan, pitch, positioning, target market, pricing, or still-forming idea with sharp, unsparing questions — extended when useful to hostile or even unfair framings — until the plan sharpens into defensible decisions, or the user concludes it isn't a good idea after all. Acts as the constructive devil's advocate that the user cannot be for themselves. Load when the user wants to stress-test, attack, pressure-test, find holes in, or play devil's advocate against something they're attached to; when they ask to be "grilled," "beat up," or told "why I'm wrong"; when they suspect their plan contains wishful thinking, fluffy language, or an unnamed elephant in the room; or when they need to convert vague aspirations into real strategic decisions (with consequences accepted). Do NOT load for ordinary code review, prose editing, or general feedback requests without an adversarial frame.
observer-pattern
Teaches the observer pattern for event-driven communication. Use when you need decoupled publish/subscribe behavior where multiple parts of your system react to state changes or events.
singleton-pattern
Teaches the singleton pattern for managing a single shared instance. Use when exactly one instance of a class or object is needed to coordinate actions across your application.
system-audit
Run a quality, sanity and efficiency audit of Ane's MEL/SRHR system (Ann/Vi/Li/Researcher team, wiki, harness, three-repo architecture): surfaces drift, inconsistencies, hygiene issues and architectural ceilings, categorised by severity, as a Tier 1 working brief with sequencing. Does NOT auto-execute fixes. Use when Ane types /system-audit, /audit, /system-check, /system-health, or asks whether anything is broken or drifting; run before any /li curate and after agent-improvement work. Different from /test (harness only), /li lint (wiki only), and /grade-system (overall quality posture rather than specific issues).
hig-components-controls
Apple HIG guidance for selection and input controls including pickers, toggles, sliders, steppers, segmented controls, combo boxes, text fields, text views, labels, token fields, virtual keyboards, rating indicators, and gauges.

Cross-references: hig-components-menus, hig-components-dialogs, hig-components-search.
ux-compare
Compare UX patterns across multiple reference apps using pattern libraries produced by ux-extract. Reads 2+ pattern-library.md files, walks them category by category, identifies where apps converge (strong signal), where they diverge (genuine design choice), what's unique to one app, and what's absent across the set. Produces an opinionated comparison document with recommendations for a new build. No browser needed — pure markdown analysis. Trigger with 'compare UX patterns', 'how do top apps handle X', 'ux comparison', 'pattern comparison across reference apps'.

fee-disclosure
Evaluate whether the substance of fee and cost disclosures is complete, accurate, and not misleading across advisory, brokerage, fund, and retirement plan contexts. Use when the user asks whether Form ADV Item 5 fee content is adequate, prospectus fee table format, Reg BI cost disclosure content, 12b-1 fee transparency, revenue sharing arrangements, wrap fee program cost-effectiveness, or ERISA 408(b)(2)/404a-5 fee disclosure content. Also trigger when users mention 'hidden fees', 'total cost to the client', 'are we disclosing all layers of fees', 'expense ratio comparison', 'fee billing in advance vs arrears', 'share class selection', or 'indirect compensation'. (For which disclosure documents must exist and when they are delivered, use client-disclosures.)
factory-pattern
Teaches the factory pattern for flexible object creation. Use when you need to create objects dynamically without using the new keyword or when object creation logic should be centralized.

Apply substantive quality and reliability grading to Ane's MEL/SRHR system (Ann/Vi/Li/Researcher team + wiki + harness + three-repo architecture): letter grades on 9 components and 10 dimensions plus OECD-DAC adapted criteria, three concrete risks, what an external evaluator would still want, and recommendations for moving the grade, with a mandatory self-grading bias note. Use when Ane types /grade-system, /grade, /quality-grade, /rate-system, or asks how good the system is. Honest grading, not flattery. Different from /system-audit (finds specific issues to fix; this grades overall quality posture).
capacitor-plugin-upgrade-v7-to-v8
