claude-app-engineering

v0.9.20

Claude app-engineering specialist team — agents (claude-solution-architect, prompt-and-context-engineer, mcp-and-server-tools-engineer, agent-sdk-engineer, eval-engineer, claude-app-ops-engineer) for building production applications on the Claude API, the Claude Agent SDK, and MCP. Covers the build-surface decision (Messages API / Agent SDK / Managed Agents), model right-sizing (Opus 4.8 / Sonnet 4.6 / Haiku 4.5, 1M context), prompt caching, tool use + structured output, MCP server authoring + Anthropic-hosted server tools (computer use, code execution, Files API, memory), evals (golden sets, LLM-as-judge), and FinOps + reliability (batch, model routing, backoff, observability). dated-and-cited knowledge bank, templates, an advisory hook (house opinions). Seams: prompt-as-artifact, security, and cross-domain architecture escalate to ravenclaude-core. Requires ravenclaude-core@>=0.7.0.

Install claude-app-engineering for Claude Code

Installs for the current user

claude plugin marketplace add IchenDEV/agent-plugin-mkt
claude plugin marketplace update agent-plugin-marketplace
claude plugin install claude-app-engineering@agent-plugin-marketplace

Paste and run these commands in a terminal with Claude Code. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually

$ git clone https://github.com/mcorbett51090/RavenClaude

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/claude-app-engineering/.

Included Skills7

agent-sdk-hook-designskills/agent-sdk-hook-design/SKILL.md

Playbook for designing Claude Agent SDK hooks (PreToolUse, PostToolUse, SessionStart, Stop) — selecting the right event, writing the handler contract, deciding advisory vs blocking behaviour, and avoiding the four common hook anti-patterns. Owned by agent-sdk-engineer.

context-budget-plannerskills/context-budget-planner/SKILL.md

Playbook for allocating a Claude context window across system prompt, retrieved documents, conversation history, and tool results — with token-budget formulas, the retrieve-vs-hold decision, and the compaction triggers that prevent context overflow. Owned by prompt-and-context-engineer.

eval-golden-set-builderskills/eval-golden-set-builder/SKILL.md

Playbook for constructing a high-signal golden evaluation set: sampling strategy, input diversity, reference-answer authoring, grader pairing, and the minimum-viable size thresholds that make a delta meaningful. Owned by eval-engineer.

llm-routing-ladderskills/llm-routing-ladder/SKILL.md

Playbook for designing a cost-optimised model routing ladder: classifying request complexity, wiring the triage→escalate flow, measuring cost-per-resolved-task, and avoiding the common over-provisioning traps. Owned by claude-app-ops-engineer and claude-solution-architect.

mcp-server-authoring-checklistskills/mcp-server-authoring-checklist/SKILL.md

Gate-by-gate checklist for shipping a production MCP server: transport selection, tool-schema quality, auth wiring, error-response contract, and the security hand-off items that must escalate to core/security-reviewer. Owned by mcp-and-server-tools-engineer.

prompt-caching-auditskills/prompt-caching-audit/SKILL.md

Step-by-step playbook for diagnosing a low cache hit rate, finding the breakpoint placement errors that cause it, and correcting them. Covers TTL tradeoffs, pre-warming, tool-definition stability, and the per-model minimum-token floors.

tool-schema-designskills/tool-schema-design/SKILL.md

Playbook for designing Claude tool definitions (name, description, JSON Schema input_schema) that maximise correct invocation, minimise hallucinated arguments, and produce clean structured output. Covers naming conventions, description prompting, schema constraints, required vs optional fields, and the forced-tool-call pattern.
