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.
-
samuel-venturin Bundle Ideas NotesConsult and update persistent idea notes for automation/testing workflows.
-
samuel-venturin Skill Commit ChangesCommit changes using atomic commits following ScanSource Brazil commit convention. Runs required checks, stages selectively, and creates well-formed commits. Never pushes automatically.
-
samuel-venturin Bundle Playwright CLIAutomates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.
-
samuel-venturin Skill Execute Tdd RedTDD-RED phase — Write all unit and E2E tests FIRST (in failing state) based on QUALITY.md acceptance criteria. Tests document the expected behavior before implementation begins.
-
samuel-venturin Bundle Release MaestroSingle-entry release automation using Python tools for tag recommendation, tag creation, release notes generation and create/update release.
-
samuel-venturin Skill QA Test TutorialWrites a manual QA test tutorial for an already-implemented ticket/feature and, by default, immediately executes it end-to-end with playwright-cli against the real dev environment, capturing screenshot evidence to attach to the Jira US.
-
samuel-venturin Bundle Testid ExtractorExtract data-testid from pages using testid-v2 plugin. Self-contained skill that handles authentication internally using e2e/auth module. Captures dynamically generated hashes and creates docs/testid-map.md for reference in E2E tests and pattern validation.
-
samuel-venturin Skill Execute Code ReviewRigorous code review against DRY, SOLID, FUNCTIONAL PROGRAMMING, CLEAN CODE, and project standards (AGENTS.md). Runs after implementation and before QA validation.
-
samuel-venturin Skill Execute ImplementationImplement in a GREEN loop (run tests, fix code, rerun) until all tests pass. Never alter tests without explicit user authorization.
-
samuel-venturin Skill Refactor SeSimplify Expressions sub-skill - Reduces complexity and improves readability of conditional logic and expressions.
-
samuel-venturin Skill Refactor RdcRemove Dead Code sub-skill - Identifies and removes unused functions, variables, imports, and dead code paths.
-
samuel-venturin Skill Refactor CleanClean Code sub-skill - Applies SOLID principles and clean code best practices.
-
samuel-venturin Skill Refactor NamingNaming Conventions sub-skill - Standardizes variable, function, and class naming for consistency and clarity.
-
samuel-venturin Skill Refactor PatternPattern Conformance sub-skill - Ensures files follow project-specific patterns and conventions documented in AGENTS.md.
-
dkpapadopoulos Skill Openspec ShipUse when shipping a completed feature and generating as-built OpenSpec docs before branch finalization
-
dkpapadopoulos Skill Prototype LabProduce 3 thin comparable variants of a proposed design with a comparison artifact and mandatory Human Validation Plan
-
dkpapadopoulos Skill Outcome ReviewUse when reviewing a shipped feature's real-world outcome in the LEARN phase — checking adoption, error, or experiment metrics after release, validating ship-time hypotheses, or deciding follow-up work — querying PostHog and creating gated follow-up Jira work
-
dkpapadopoulos Skill Skill ScaffoldUse when creating new skills, commands, or plugins — emits repo-native seed files (SKILL.md skeleton, routing entry, test snippets)
-
dkpapadopoulos Skill Batch ScriptingUse when transforming, migrating, refactoring, or generating across many files at once — codebase-wide renames, 50+ file migrations, mass test/doc generation, framework upgrades — via claude -p with manifest, dry-run, and log-based retry
-
dkpapadopoulos Skill Capture KnowledgeUse when capturing a durable, team-relevant learning into the committed .claude/knowledge/ base — a gotcha, decision, convention, or runbook worth sharing with teammates' agents. Human-gated.
-
dkpapadopoulos Bundle Project VerificationUse when you need to run the repo's own declared test/lint/type gate locally and emit pass/fail evidence — during REVIEW, before requesting code review, or on a request to run the tests or verify the build — discovering the gate from CLAUDE.md, Makefile, pyproject, or .verify.yml
-
dkpapadopoulos Bundle Unified Context StackUse when any SDLC phase needs external docs, dependency internals, cross-session memory, or feature specs — provides tiered context retrieval across External Truth (docs), Internal Truth (dependencies), Historical Truth (memory), and Intent Truth (feature specs) with graceful degradation based on installed tools.
-
dkpapadopoulos Skill Incident Trend AnalyzerOn-demand postmortem trend analysis — recurrence grouping, trigger categorization, MTTR/MTTD from canonical docs/postmortems/ corpus
-
dkpapadopoulos Skill Implementation Drift CheckUse when verifying an implementation still matches its spec or plan — during REVIEW or SHIP, or on demand to check drift, confirm you are still on plan, or run a spec check — surfacing spec deviations, unvalidated assumptions, and untested code paths against Intent Truth

-
flpbalada Skill Graph Thinking 2Apply graph-based thinking to visualize complex relationships and solve problems non-linearly. Use when mapping dependencies, analyzing systems, exploring interconnected concepts, or designing architectures.
-

-
flpbalada Skill Progressive Disclosure 2Reduce complexity by revealing information progressively. Use when designing onboarding, complex forms, feature-rich interfaces, or any experience where showing everything at once would overwhelm users.
