Shell scripting plugin: shell and automation agents, script scaffolding, and conventions for consistent development with shellcheck and shfmt
Use this agent for CI/CD pipelines, deployment scripts, Docker entrypoints, cron jobs, Makefiles, GitHub Actions composite actions, and systemd units. Invoke for building reliable automation that handles signals, environment variables, rollback, and health checks. Examples: writing Docker entrypoint scripts with exec and signal forwarding, building Makefiles with phony targets and dependency graphs, creating GitHub Actions composite actions, or implementing deployment scripts with zero-downtime rollback.
Use this agent for Bash 4+ and POSIX sh scripting with emphasis on safety, portability, and shellcheck compliance. Invoke for writing robust scripts with proper error handling, argument parsing, signal traps, and parameter expansion. Examples: building deployment scripts with rollback, writing portable installers, implementing CLI tools in pure bash, refactoring legacy shell scripts for safety and maintainability, or debugging complex pipelines.
This skill should be used when implementing common shell script patterns such as argument parsing, logging, cleanup, temp files, script directory resolution, input validation, process management, and portability helpers. It provides ready-to-use patterns with CORRECT and WRONG examples.
This skill should be used when working on shell scripts, writing bash or sh code, reviewing shell scripts, or running shell-based automation. It covers safety rules, style rules, portability rules, and structure rules for production-quality shell scripting.

Foundation — ccfg-core is the base plugin. Install it first. It provides cross-cutting
workflow rules (planning discipline, scope control), 22 general-purpose agents, security hooks
(secret scanning, dangerous command blocking), and GitHub MCP integration.
Language — One plugin per language. Each provides framework-specific agents, project scaffolding commands, coverage automation, and conventions for the language's standard toolchain. Enable only what you use.
Data — Database-specific agents and conventions. Each plugin covers schema design, query optimization, migration patterns, and the database's operational best practices.
Infrastructure — Container, CI/CD, and orchestration plugins. Dockerfile optimization, GitHub Actions workflow design, and Kubernetes manifest/Helm chart conventions.
Some settings can't be configured through plugins (permissions allow-lists, alwaysThinkingEnabled,
initial enabledPlugins). A bootstrap script handles these one-time settings.json updates.
The bootstrap script is under development. See the design doc for details on what it will configure (decision D4).
This marketplace focuses on coding conventions and workflow rules. For complementary capabilities (documentation retrieval, semantic code navigation, code review, browser testing), see the Third-Party Recommendations.
Architecture decisions, plugin anatomy, and the insights report that informed these plugins are documented in docs/DESIGN.md.
