Complete feature development workflow for Reactive Agents. Orchestrates the correct sequence of skills for any feature type. Use at the start of any non-trivial implementation task to route to the right skills and follow the right order.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Reactive Agents Feature Development Workflow ## Step 0: Route to the right skills | Work | Load | |---|---| | Kernel (phase, guard, meta-tool, custom kernel) | `kernel-extension` | | Provider / adapter / streaming | `provider-streaming` | | MCP (docker tools, transport, container lifecycle) | `mcp-integration` | | New service in an existing package | `implement-service` | | New package | `build-package` | Always also: `agent-tdd` (tests first), `effect-ts-patterns` (all code), `repo-tool` (commands below). ## Step 1: Orient ```bash bun run repo status # branch, plans, debt bun run repo scope <files you will touch> # owner/warden, checks, docs bun run repo find "<symbol or topic>" # then: bun run repo outline <file>, Read a range ``` Read the affected package's entry point first (`architecture-reference` names it) and its upstream layers. Changes to `core` / `llm-provider` need downstream rebuild and type verification. Domain-scoped edits go through the owning warden (AGENTS.md ownership table). ## Step 2: Failing test first (`agent-tdd`) Write ONE failing test, run it, confirm the right failure, write minimal code, rerun, then edge cases: …

How to install
mdr add tylerjrbuell/reactive-agents-ts/reactive-feature-dev@sha256:dd2197a14c279590The line at the top of this page pins the label git:20261103.92630ca, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
