eSIM API work requires signed requests, correct identifiers, and careful production actions. This skill guides eSIM Access operations from package lookup through orders, usage, webhooks, and refunds.

Developers need predictable failure output when testing agent tool handling. This skill prints stdout, stderr, and a simulated stack trace before exiting with an error.

Build systems often hide dependency failures or surface them without useful context. This skill provides a small failing fixture for checking how Claude, Codex, and Claude Code expose build step errors.

Manual page checks slow down web testing and content review. This skill opens pages in Chromium and returns screenshots, text, or HTML.

Claude Code hooks are powerful but easy to configure incorrectly. This skill guides hook creation, validation, and troubleshooting with security checks.

Claude Code hooks are powerful but easy to misconfigure. This skill guides hook creation, configuration, validation, and security review.

Rust Lambda functions can waste cost through slow I/O, cold starts, and poor memory settings. This skill reviews handlers and deployment settings, then suggests concrete performance and cost improvements.

Rust Lambda functions can suffer slow first responses when binaries are large or initialization is heavy. This skill guides Claude, Codex, and Claude Code through concrete optimizations for build settings, dependencies, and deployment.

Manual browser checks are slow and hard to repeat. This skill guides Claude, Codex, and Claude Code through WebDriver automation.

Marketplace maintainers must release plugins without mixing versions across a shared repository. This skill guides validation, version updates, tags, pushes, and GitHub releases for one plugin at a time.

Long AI tasks lose context and coordination across sessions. This skill uses GitHub Issues, checkpoints, and worktrees to preserve state and guide phase transitions.

Teams need consistent handoffs between development, testing, review, and merge phases. This skill validates allowed transitions, delegates thread changes, and updates workflow memory.

Teams need a quick view of GitHub Elements workflow health without changing issue state. This skill produces a read-only status overview for active threads, phases, and warnings.

GitHub Elements teams need structured visibility into workflow health, metrics, and epic progress. This skill produces detailed reports for metrics, compliance, and epic analysis.

Starting issue work requires validation, labels, comments, and local setup. This skill coordinates those steps for a specific GitHub issue number.

Long development sessions can lose state across tools, agents, and handoffs. This skill records a structured checkpoint in the active GitHub Issue thread and GHE_REPORTS.

Schema changes can break deployments when rollback, locking, and compatibility are missed. This skill helps plan and review backend migrations for safer database evolution.

Parallel development can create branch, port, and cleanup confusion. This skill guides Git worktree creation, listing, removal, and troubleshooting with isolated local settings.

Voice agent failures are hard to diagnose when audio, WebRTC, tokens, and process state interact. This skill gives focused checks, workflows, and helper scripts for LiveKit and Letta debugging.

Running several branches locally can cause port and configuration conflicts. This skill invokes a project slash command to create isolated worktrees with separate ports and startup details.
