research-tools

dev-digest-ai-marketplace

A Claude Code plugin marketplace for Spec-Driven Development Engineering, extracted from the DevDigest project. It ships the SDD agents, skills, and workflows as installable plugins, plus a static, client-side searchable catalog site.

One repo holds the catalog and every plugin's source, so the whole thing is reviewable in a single pull request. A plugin can later move to its own repo, leaving this as the catalog.

Connect it

/plugin marketplace add VadimPoltoratskiy/dev-digest-ai-marketplace
/plugin install sdd-engineering@dev-digest-ai-marketplace

Then /plugin marketplace update to refresh the catalog and /plugin update <name>@dev-digest-ai-marketplace to upgrade an installed plugin. (See docs/RELEASES.md for the difference.)

Plugins

Plugin	What it gives you
sdd-engineering	The SPEC → PLAN → implement → verify → retro loop: agents Spec Creator, Implementation Planner, Implementer, Plan Verifier, the Run Plan skill, the /implement command, and the Retro workflow.
engineering-paved-path	The shared dependency: 14 reusable, on-demand engineering skills (architecture, testing, security, and stack best-practices). Skills only — no agents.
research-tools	Read-only research agents — Researcher (cited codebase + web research), plus Brainstorm and Doc Writer.
architecture-review	The Architecture Reviewer agent — layer boundaries, placement, RSC, and security checks with a structured finding report.

Dependency graph

sdd-engineering is the entry point; the installer resolves the rest. Version constraints are fixed, and the shared dependency is installed once:

[email protected]
├── engineering-paved-path@^1.0.0
├── research-tools@^1.0.0
└── architecture-review@^1.0.0
    └── engineering-paved-path@^1.0.0   # one shared installation

Shared skills and cross-agent dispatches are referenced with an explicit plugin:artifact namespace — an agent preloads engineering-paved-path:security, and the Run Plan skill dispatches architecture-review:architecture-reviewer — so every reference has one canonical source. node scripts/preload-smoke.mjs checks that they all resolve.

How they fit together

 spec-creator ─▶ implementation-planner ─▶ implementer ─▶ plan-verifier ─▶ architecture-reviewer
   SPEC-NN.md          PLAN.md              code+tests     VERIFICATION.md      findings
        ▲                                                       │
        └── researcher (research-tools)      Run Plan orchestrates implementer→verify→review
                                             Retro records the merge in an append-only ledger

See the sdd-engineering README for the full loop.

Catalog site

A static SPA in site/ with client-side fuzzy search over every plugin and artifact — deployed to GitHub Pages by .github/workflows/pages.yml. The search index is built from the plugins by scripts/build-index.mjs. Design and data model: docs/SITE-SPEC.md.

Local preview:

node scripts/build-index.mjs
cd site && python3 -m http.server 8000   # → http://localhost:8000

Contributing

Read CONTRIBUTING.md and docs/PLUGIN-GUIDELINES.md. In short: follow the plugin structure, reuse shared skills via dependencies, no secrets or absolute paths, and make node scripts/build-index.mjs --check pass before opening a PR.
