A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages
This repository also configures its own agents. See what agent-skills-standard tells them →

Analyze conversation corrections to detect skill gaps and prepare targeted skill-library maintenance tasks. Use after any session with user corrections, rework, or retrospective requests. After finding correction loops, also load +common/common-learning-log to persist mistake entries to AGENTSLEARNING.md.

Skill Claude CodeCodex
Standardizes the creation and evaluation of high-density Agent Skills (Claude, Cursor, Windsurf). Ensures skills achieve high Activation (specificity/completeness) and Implementation (conciseness/actionability) scores. Use when: writing or auditing SKILL.md, improving trigger accuracy, or refactoring skills to reduce…

Skill Claude CodeCodex
Standardize SRS and FRS specifications for technical behavior, interfaces, data contracts, quality constraints, and verification mapping. Use when writing SRS, functional specification, system behavior requirements, API/data contracts, or non-functional thresholds.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Generate user-facing release notes for the App Store and Google Play from git history (App Store <=4000 chars, Google Play <=500). Use when generating release notes, app store changelog, play store release, or "what's new" text for a mobile app.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Guides quality-first TDD for new behavior, bug fixes, and test changes. Selects the smallest test layer, proves a distinct regression risk, and runs bounded RED-GREEN-REFACTOR verification.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Enforce session-cost telemetry and execution-metadata reporting. Use when explicitly invoking getsessioncost, reporting token/cost usage, applying telemetry or cost guidance during a workflow handoff, or writing artifacts/session-cost.md at a workflow terminal state.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Design distinctive, production-grade frontend UI with bold aesthetic choices. Use when building web components, pages, interfaces, dashboards, or applications in any framework (React, Next.js, Angular, Vue, HTML/CSS).
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Standardizes visual audits, responsive design, and behavioral testing for web apps. Use to verify a web UI fix or cross-browser behavior; defer backend API refactors, Playwright installation/tooling setup, and Appium/mobile automation.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Rules for writing concise, token-efficient workflow and skill files. Prevents over-building that requires costly optimization passes. Use when creating or editing workflow files, SKILL.md files, or new skill definitions.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Idiomatic JavaScript patterns and conventions for maintainable code.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Modern JavaScript (ES2022+) patterns for clean, maintainable code.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Development tools, linting, and testing for JavaScript projects.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Drives iOS/Android mobile devices via Appium MCP. Use for verifying mobile bugs, E2E tests, and navigating real device clouds (LambdaTest/BrowserStack).
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Investigate requirements via atomic AC decomposition, actor/permission matrices, and truth-table edge cases; enforce User Story standards (scope fences, platform tags, toggles). Use when writing/reviewing Stories or AC with multi-condition logic, feature toggles, or market variants (VN/MY/SG).
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Trigger only when the user explicitly requests live Jira or Zephyr retrieval, existing-link inspection, linking authored test cases, label updates, or stale-link audits. Do not trigger for analysis-only prompts such as 'Analyze the acceptance criteria for TICK-4521', supplied acceptance criteria, test-case authoring…
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Standardizes token-efficient browser automation via playwright-cli. Use for web verification, navigation, and capturing snapshots/logs.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Write or review manual Zephyr test cases with 1-condition-per-TC granularity, ModuleAction on Screen when Condition naming, platform prefix rules, and High/Normal/Low priority classification. Use for test-case authoring and review; defer Jira traceability, linking, and pushing cases to Zephyr.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Audit test coverage health, gaps, and QE debt for Jira stories or epics. Produces coverageanalysisreport.md with AC-to-TC heatmap, risk scores, and prioritized action plan. Use when assessing coverage percentage, pre-release readiness, sprint readiness, or identifying missing test cases. Do NOT use for TC creation …
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Generate Zephyr test cases from Jira stories: parse acceptance criteria and business rules, impact-analyze existing TCs (update vs. create new), and draft correctly named test cases. Use for AC-to-test generation; defer post-generation Jira linking and manual test-case quality review.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Ingest a provided design artifact - screenshot, drawio, Mermaid, PlantUML, Excalidraw, slides, PDF, or IaC - into a reviewable fact sheet. Probes for embedded structure before vision, marks per-edge confidence, treats extracted text as data. Use when someone hands over a design to review.

Skill Claude CodeCodex
Select infrastructure components by the constraint each removes: load balancers, caches and invalidation, queues and pub/sub, CDN, API gateway, rate limiting, consistent hashing. Use when choosing cache, queue, replica, or edge layers; defer engine tuning to the database category.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Answer classic system design problems as constraint-to-solution sketches and coach interview practice: URL shortener, rate limiter, news feed, chat, notification, autocomplete, crawler, unique id. Use for interview practice or naming the closest known shape for a new problem.
HoangNguyen0403/agent-skills-standard
Skill Claude CodeCodex
Select how services talk: REST, gRPC, GraphQL, WebSocket, SSE, or webhook per hop, sync versus async per flow, service discovery mode, and DNS/edge routing. Use when choosing a protocol or API paradigm; defer REST contract detail (status codes, pagination, OpenAPI) to common-api-design.
