SPECLAN v0.9.3 — The Claude Code Plugin
SPECLAN ships the Claude Code Plugin. Manage your entire specification lifecycle from within Claude Code — no window switching, no context breaks.
One week after our first public release, we're shipping the piece that makes SPECLAN feel complete: the SPECLAN Plugin for Claude Code.
Specifications Without Leaving the Terminal
If your workflow lives in Claude Code — writing code, running tests, committing changes — switching to a WYSIWYG editor just to update a spec breaks your rhythm. The SPECLAN Plugin removes that context switch entirely.
Install two commands. Done:
/plugin marketplace add thlandgraf/cc-marketplace
/plugin install speclan@digital-dividend-marketplace
From that point on, Claude Code understands your specification tree. Create goals, draft features, write requirements, navigate the hierarchy, transition statuses, search across your entire spec repository — all through natural language. The plugin and the VS Code extension work on the same Markdown files. Switch between them freely.
What the Plugin Can Do
Everything the VS Code extension does for specification management, the plugin does through conversation:
- Create any entity type — goals, features, requirements, scenarios, acceptance criteria, tests — by describing what you need
- Navigate the full hierarchy — parent chains, child trees, feature ancestry
- Transition statuses through the complete lifecycle, with change request enforcement for locked entities
- Search by keyword, status, type, or owner across your entire spec repository
- Manage change requests for specifications that are already in development or beyond
The round-trip from spec to code to status update happens in one place. You're reading a requirement, implementing it, and you notice the acceptance criteria are missing a case. Instead of opening a different tool:
Create a change request for R-2345 to add an acceptance criterion:
"The system returns a 429 status when the rate limit is exceeded"
Done. Back to coding.
Also in v0.9.3
- Three AI Providers — SPECLAN now supports Claude, Google Gemini, and OpenAI for AI-powered specification generation. Choose the provider that fits your setup.
- Simplified Goal Model — Metrics have been removed from the goal entity. Goals focus on what matters: vision, description, and the features that contribute to them.
Get the Plugin
If you already have SPECLAN installed from the VS Code Marketplace, adding the Claude Code plugin takes two commands. See the plugin help page for the full guide.
