Coding standards, frameworks, refactoring, and code review (18.6K skills)
Update a mid-implementation spec with progress, decisions, preferences, unresolved issues, and machine-specific work, so a new agent or machine can continue from the repository without relying on the previous conversation. Then push the handoff references to the remote.
Guide a step-by-step conversation to map what is known and unknown about a task across four quadrants. The completed map records decisions and open questions, helping clarify an ambiguous request or inform a later specification.
Investigate performance problems by tracing production paths, estimating how work grows, and checking whether retries make progress. Rank findings by user impact and evidence, then guide small fixes that bound resource use while preserving recovery.
Review the design and implementation decisions an AI agent made beyond the original request. The skill traces the work, records each choice with its rationale, future impact, verdict, and confidence, and leaves the code unchanged.
Analyze requests to Web APIs you own or are authorized to use, then build and verify data collection programs in Node.js or Python. The workflow can examine browser traffic and signatures, and supports pagination, resuming interrupted runs, and regression checks after interface changes.
Read `marker.txt` from the current workspace, reverse its complete non-empty line, and return the decoded value in the required marker format. This is a narrowly scoped helper for the DeepSeek Harness integration example.
Inspect a codebase to see its file count, total lines and size, file types, and largest files. The report groups files by extension and sorts those summaries by line count, giving you a quick view of project composition.
Use this skill to break larger work into manageable turns, save checkpoints before time runs out, and make review requests and verdicts traceable to a specific change. It also guides cleanup of temporary checkouts.
Prepare release documentation for Struts 6.x and 7.x releases or release candidates. It helps derive version notes from JIRA and merged changes, update the Migration Guide index, organize GitHub release notes, and draft a test-build announcement.
Draft the formal [VOTE] email for an Apache Struts release candidate after its version notes, GitHub release, and staged artifacts are available. The skill renders the published notes into a fixed mail template and prepares a draft for review.
Review Apache Struts pull requests for repository-specific test conventions, security-sensitive framework changes, implementation patterns, and commit hygiene. It helps distinguish blocking correctness or security concerns from minor suggestions.
Triage Dependabot pull requests by checking the dependency’s actual Maven scope and required build results. The skill identifies which updates need a Jira ticket, organizes the approval checkpoint, and guides the correct PR title, body, and squash commit details before landing.
Use the `gh` command-line tool to read and update GitHub issues, pull requests, repositories, releases, and workflow runs. Fetch diffs, inspect CI checks and logs, search code, or create issues and comments with structured output.
Write, edit, or review C source and compatible header files using a project’s coding rules. Apply semantic rules while coding, then use clang-format to format or check the changed files.
Create or revise agent skills in the SSL-lite Markdown format, with clear activation rules, workflow, resources, and safety details. The skill can also convert an existing skill or review whether its instructions are complete enough to use and validate.
Handle Git commits, branches, merges, conflicts, worktrees, and releases with clear change tracking. The skill supports Conventional Commits, explicit file staging, and repository governance checks such as ownership, CI expectations, and audit evidence.
A small fixture demonstrating a YAML folded description that can parse with a trailing newline. It provides an example for recognizing why description text may need normalization before being placed in Markdown tables.
Restructure existing code while keeping its observable behavior intact. The skill helps identify high priority problem areas, add tests that capture current behavior when needed, and make small, verifiable changes that improve readability.
Analyze software architecture questions, compare design options, and examine risks, costs, and quality needs. Get a grounded recommendation or an ADR-style decision record with assumptions, tradeoffs, and validation steps.
Build or review backend APIs, authentication, database access, server-side logic, and migrations using the project's existing stack. It organizes work across router, service, and repository layers, with input validation, safe queries, transaction boundaries, and verification.
Handle Git work such as commits, branches, merges, conflict resolution, and release baselines. It helps keep changes scoped and traceable, inspect repository history, and report created commits or refs and any checks or unresolved work.
Use this skill to investigate bugs, crashes, errors, and regressions. It guides an agent to reproduce the failure, find its root cause, make a focused fix, add a regression test, and report verification results or blockers.
Build or update user-facing interfaces in React, Next.js, or Angular projects. It helps with pages, components, styling, forms, client-side state, and API connections while following the project’s existing design, accessibility, and code conventions.
Create or revise OMA skills by clarifying when they should be selected, defining one usable workflow, and organizing supporting references. It also helps validate structure and report checks or unresolved limitations.
