Plugins that make Claude Code better at its job.
Claude Code is powerful out of the box, but it has gaps. It forgets skills mid-session. Commits are messy. Building AI artifacts is trial-and-error. Code ships without validation. These plugins fix that.
Add the marketplace, then install any plugin:
/plugin marketplace add xobotyi/cc-foundry
/plugin install <plugin-name>
Claude skips skills and forgets about them mid-session. This plugin injects a Skill Enforcement Framework via lifecycle hooks that forces Claude to evaluate which skills apply at every checkpoint: user prompt, after reading files, after editing, and after loading skills. Skills are treated as non-atomic — phase shifts (coding to testing) trigger re-evaluation of unread references from already-loaded skills.
/plugin install skill-enforcer
Messy commits — mixed changes, vague messages, wrong order. The /commit command enforces an 8-step pipeline: identify
logical units in the diff, plan commit order (style to refactor to fix to feature), run quality gates, self-review,
stage selectively, validate messages against conventions, commit, and verify. Each message runs through automated
validation before execution.
/plugin install git-commit
Planning is either too shallow or too detailed. This plugin provides a four-stage pipeline that produces artifacts consumable by both humans and agents: design documents (problem analysis and recommendation), technical designs (component mapping and sequencing), task decomposition (actionable hierarchies with acceptance criteria), and task creation (issue tracker items). Each stage builds on the previous with explicit approval gates.
/plugin install the-blueprint
Claude writes code before understanding what exists — guessing APIs, skipping tests, multiplying abstractions. This
plugin provides a coding skill that enforces a discovery-first workflow (Discover, Plan, Implement, Verify) and a
software-engineer output style with LSP-first navigation and engineering judgment. Runs before language-specific
skills as a prerequisite.
/plugin install the-coder
Code quality is checked manually or not at all. This plugin provides a two-level validation pipeline:
quality-validation checks that deliverables match the original request before completion, and
code-quality-evaluation orchestrates 8 specialized review agents (naming, complexity, comments, tests, error handling,
security, observability, documentation) that evaluate code in parallel. All agents are read-only — they report, you
decide.
/plugin install the-crucible
No visibility into context window usage, cost, or model. This plugin installs a 3-row status line to your user-level Claude configuration showing output style, model, session cost, context window remaining, cache hit rate, and current working directory. Color urgency increases as context approaches limits. Auto-syncs on every session start and survives agent directory changes.
/plugin install the-statusline
Agentic workflow mechanics — the foundational skills that make working with Claude Code effective across sessions and
teams. The claude-md skill applies prompt engineering principles to CLAUDE.md files: what belongs where, writing
instructions Claude actually follows, diagnosing why rules get ignored (buried, vague, stale, contradictory), and
systematic improvement. The handoff skill produces structured transfer documents when work crosses context boundaries
— session restarts, teammate delegation, async resumption — preserving decisions, constraints, and remaining work in
500-2000 tokens while dropping noise.
/plugin install the-workflow
Creating prompts, skills, agents, and output styles is guesswork without structured guidance. This plugin provides
skills encoding best practices for each artifact type: prompt-engineering (foundation), skill-engineering,
subagent-engineering, output-style-engineering, and claude-code-sdk (reference). All skills build on
prompt-engineering fundamentals. Includes an ai-engineer output style for collaborative artifact work.
/plugin install ai-helpers
Go has strong idioms that differ from other languages — premature abstraction, incorrect error handling, interface
misuse, and concurrency bugs are common pitfalls. This plugin provides a golang skill covering conventions, error
handling, interfaces, concurrency, testing, and project structure, plus a templ skill for type-safe HTML templating
with component composition, attribute handling, and JS integration.
/plugin install golang
Claude knows JS/TS syntax but defaults to outdated patterns, mixes module systems, and ignores runtime-specific APIs.
This plugin provides five skills: javascript (core language conventions), typescript (type system and strict mode),
nodejs (Node.js runtime APIs), bun (Bun runtime APIs), and vitest (testing framework practices). Skills activate
automatically based on file context.
/plugin install javascript
Infrastructure work — Ansible playbooks, Docker containers, Proxmox clusters, network segments — requires deep domain
knowledge that generic coding assistants lack. Without it, agents produce configurations with insecure defaults, no
idempotency, and naive networking. This plugin provides six skills: devops (foundational discipline — what good
infrastructure looks like, analogous to the-coder/coding), ansible (playbooks, roles, vault, collections, molecule
testing), containers (Docker/Podman, Compose, image optimization, security), proxmox (VMs, LXC, storage backends,
clustering, API automation), unraid (arrays, Docker, VMs, shares, plugins), and networking (VLANs, firewalls, DNS,
reverse proxies, VPN, TLS). The devops skill runs in a sandwich pattern: principles first, tool skill, then
verification.
/plugin install infrastructure
Browser development requires knowledge beyond general programming — CSS layout systems, accessibility standards,
framework-specific patterns. This plugin provides five skills: css (conventions, layout, SCSS/SASS, responsive design,
methodologies), react (component patterns, hooks, state, performance, testing), vue (Composition API, reactivity,
composables), svelte (Svelte 5 runes, SvelteKit conventions), and accessibility (WCAG 2.2, ARIA, semantic HTML,
keyboard navigation). Keeps platform discipline separate from language discipline.
/plugin install frontend
Building reliable services requires consistent approaches to observability and instrumentation. This plugin provides
four skills: observability (three pillars — logging, metrics, tracing — their interconnection and high-level
practices), prometheus (metric types, naming, labels, PromQL, alerting), statsd (metric types, UDP push model,
DogStatsD extensions), and otel-tracing (spans, context propagation, instrumentation, sampling, semantic conventions).
Technology-agnostic guidance in observability; tool-specific depth in the others.
/plugin install backend
CLI platform discipline — command-line interface design, shell scripting conventions, and terminal UX patterns. Two
skills cover the full CLI surface: cli handles the design layer (argument conventions, output streams, exit codes,
configuration hierarchy, signal handling) for CLIs written in any language, while shell-scripting handles the
implementation layer (strict mode, quoting, portability, error handling) for scripts written in shell.
/plugin install cli
PHP language discipline targeting 8.5+. Two skills cover the full PHP surface: php handles conventions, type
declarations (union, intersection, DNF), enums, readonly classes, property hooks, closures, Fibers, error handling,
Composer, PSR-4/PER-CS, and project structure, while phpunit handles testing conventions (test structure, data
providers, assertions, stubs vs mocks, attributes, configuration). Bundled Intelephense LSP for semantic code
navigation.
/plugin install php
Python language discipline targeting 3.14+. Two skills cover the full Python surface: python handles conventions,
modern idioms, type annotations (built-in generics, | unions, protocols), data classes, pattern matching, exception
handling, packaging (pyproject.toml, uv, ruff), and project structure, while pytest handles testing conventions
(fixtures, parametrize, markers, mocking, async testing, conftest patterns).
/plugin install python
