Coding & Dev Tools
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.

-
athola Skill Blast Radius 2Analyzes code change impact with risk scoring and affected-node mapping. Use before merging to understand what a change touches and what lacks test coverage.
-
athola Bundle Shell Review 2Audits shell scripts for correctness, portability, and common pitfalls. Use when reviewing shell scripts or before committing shell changes.
-
athola Skill Architecture Paradigm Event Driven 2Applies event-driven async messaging to decouple producers and consumers. Use when designing real-time or multi-subscriber systems needing loose coupling.
-
athola Skill Architecture Paradigm Client Server 2Applies client-server architecture for web/mobile apps. Use when designing systems with centralized backend services, trust boundaries, or offline-first sync.
-
athola Skill Architecture Paradigm Domain Driven 2Models a business in its own language. Use when the domain has real business rules to capture.
-
athola Skill Architecture Paradigm Microservices 2Applies microservices for independent deployment and per-service scaling. Use when teams need autonomous release cycles with distinct capability scaling needs.
-
athola Skill Architecture Paradigm Service Based 2Applies coarse-grained service architecture for deployment independence. Use when independent deployment is needed but shared databases rule out microservices.
-
athola Skill Architecture Paradigm Functional Core 2Applies Functional Core, Imperative Shell to isolate logic from side effects. Use when business logic is entangled with I/O or unit tests are slow and brittle.
-
athola Skill Architecture Paradigm Modular Monolith 2Applies modular monolith with enforced internal boundaries. Use when teams want service-level autonomy without distributed system overhead.
-
mahasvin24 Skill DocumentDocument durable repository-local context across conversations. Use when asked to remember, log, or recover important project information, or when work reveals decisions, constraints, discoveries, failed approaches, gotchas, or unresolved threads that future agents or developers will need. Do not use as an exhaustive activity log or user-facing changelog.
-
mahasvin24 Skill Grill MeGrill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.
-
mahasvin24 Skill RefactorRefactor existing code for clarity, maintainability, or reduced complexity while preserving behavior. Use when asked to clean up, simplify, reorganize, deduplicate, or remove proven dead code. Do not use for feature work or intentional behavior changes.
-
athola Bundle Quota Management 2Tracks quotas, monitors thresholds, and degrades gracefully for rate-limited APIs. Use when integrating external services that impose rate or cost limits.
-
athola Bundle Service Registry 2Registers external services with health checks, central config, and unified execution. Use when integrating multiple external services needing coordination.
-
athola Skill Hook Scope Guide 2Select hook scope (plugin, project, global) by audience. Use when authoring a hook.
-
athola Bundle Subagent Testing 2Test skills via TDD in fresh subagents. Use when validating behavior or preventing bias.
-
athola Bundle Gemini Delegation 2Delegates tasks to Gemini CLI implementing delegation-core for Google's models. Use when delegation-core selects Gemini or 1M+ token context is needed.
-
athola Bundle Karpathy Principles 2Pre-implementation gate covering think-first, simplicity, surgical edits, and verifiable goals. Use when starting implementation to verify the approach.
-
athola Skill Loop Optimization 2Decides hand-vs-compiler for loop transforms (unrolling, SIMD, fusion, branchless). Use when reviewing/authoring a hot loop or tempted to hand-optimize one.
-
athola Skill Night Market Build And Env 2Rebuild the dev environment: uv, Python tiers, pins, traps. Use when onboarding or toolchain breaks. Do not use for daily commands; use night-market-operations.
-
athola Skill Stack Create 2Initializes a stacked branch set from an ordered plan, one branch per slice with parent-child links. Use when a plan has 2+ sequentially dependent changes.
-
athola Skill Stack Rebase 2Cascades a rebase through an entire PR stack after a base PR merges or upstream changes. Use when a stack needs to incorporate new base branch commits.
-
athola Bundle Test Updates 2Updates, generates, and validates tests using git-workspace context and TDD/BDD methodology. Use when code changes require new or updated test coverage.
-
athola Bundle Slop Detector 2Detects AI-generated writing patterns in prose. Use when reviewing docs for slop, vague language, or identity leaks before publishing.
-
athola Bundle Style Learner 2Extracts writing style patterns from exemplar text into a reusable profile. Use when creating a style guide or learning a specific author's voice.
-
athola Bundle Tech Tutorial 2Plans, drafts, and refines technical tutorials for developers. Use when writing step-by-step guides or getting-started walkthroughs backed by working code.
-
athola Bundle Voice Extract 2Extracts a user's writing voice from text samples via SICO comparative analysis. Use when building a voice profile for consistent generation.
-
athola Skill Call Chain 2Traces execution paths through the code graph with criticality scoring and Mermaid charts. Use when understanding how a function propagates through the system.
-
athola Bundle Elegant Code 2Guide minimal code via a decision ladder with full safety, edge, and negative-case coverage. Use when adding code, choosing a dependency, or auditing a diff.
-
chinthakat Skill Design CritiqueReview a proposed design, plan, architecture or RFC in one adversarial pass and produce ranked findings, each with a concrete failure scenario. Use when asked to review, critique, poke holes in or sanity-check a design before it is built, and before committing to anything expensive to reverse.
-
chinthakat Skill Offline First SyncBuild or debug an app that has to keep working with no network — local writes, a queue, and reconciliation on reconnect. Use when adding offline support, when work is lost on a dropped connection, when sync produces duplicates or silently drops records, or when photos and other large files need to survive being captured out of coverage.
-
chinthakat Skill Versioned PublishingDesign or change content, templates, forms, quizzes, pricing rules or configuration that is authored, published, and then consumed by sessions already in progress. Use when editing a published item changes what someone mid-way through sees, when "why did this record's score change?" has no answer, or when retiring an item breaks historical records.
