General-purpose Sombra usage — saving web pages, browsing collections, distilling context, and working with your research library. Use when the user mentions research, documentation, collections, context, saving, or looking something up, and no specific workflow skill (project, spec, pickup, research) applies.
Pick up work on a project or feature by loading its living tracker from Sombra. Shows progress and highlights what's next. Adapts to context — uses git awareness in code environments, plain status elsewhere. Use when starting a session to continue previous work, or "where was I", "resume", "pick up", "what's next".
Create and manage a living project tracker in Sombra that persists across conversations. Use for any multi-phase effort — house purchase, renovation, content strategy, product launch, event planning, learning goals, or anything with phases and evolving plans. Works in Claude Desktop, Claude.ai, ChatGPT, Claude Code, and any MCP client.
Deep technical research on APIs, libraries, and frameworks using Sombra as a persistent knowledge base. Use when the user needs to learn a new API, evaluate a library, build reference documentation for a technology, understand migration paths between versions, or says things like "research this API", "build me a reference for X", "what's the right way to use Y", or "I need to understand Z before I start coding".
Create and manage a living spec for a software feature, tracked in Sombra across conversations. Extends the project skill with git branch context, code paths, and commit-based progress detection. Use when the user is building a feature, planning a migration, or says "spec this out", "track this feature", "create a living spec".

Living documentation that persists across conversations. Track projects, manage feature specs, and build technical references — all stored in Sombra so you can pick up exactly where you left off.

Go to Settings → Connectors → Add Custom Connector. Enter "Sombra" as the name and https://sombra.so/mcp as the URL. Click Connect and log in.
In ChatGPT, go to Settings → Apps, enable Developer mode, click Create App, and set the URL to https://sombra.so/mcp with auth type OAuth.
Add to opencode.json in your project root (or ~/.config/opencode/opencode.json for global):
{
"mcp": {
"sombra": {
"type": "remote",
"url": "https://sombra.so/mcp"
}
}
}
OpenCode handles OAuth automatically — it will open your browser to log in on first use.
Connect to https://sombra.so/mcp via Streamable HTTP with OAuth 2.1. See sombra.so/mcp for details.
On first use, you'll be prompted to connect your Sombra account via OAuth. Free accounts work — no credit card required.
Sombra tools activate automatically when you mention research, collections, saving, or looking something up. Save web pages, browse your library, distil collections — no slash command needed.
/sombra:project — Living project trackerTrack any multi-phase effort across conversations: house purchase, renovation, content strategy, product launch, learning goals. Works in Claude Desktop, Claude.ai, ChatGPT, and Claude Code.
/sombra:project Kitchen Renovation
Creates a Sombra collection with structured phases, checkboxes, a decisions log, and open questions. Updates surgically across sessions — no rewriting the whole document when one item changes.
/sombra:spec — Living feature specEverything in project, plus git branch context, code path references, and automatic tracker updates from git events. For software features. Requires git access (Claude Code).
/sombra:spec Auth Rework
Tracks which branch, which files, which items are done — and can cross-reference your git log to suggest what to check off.
/sombra:pickup — Pick up where you left offLoads an existing project or spec, shows what's changed, and highlights the next step. Adapts automatically — git-aware in a repo, plain status report elsewhere.
/sombra:pickup
/sombra:pickup Auth Rework
/sombra:update — Force-sync a trackerPush updates into an existing project or spec tracker. Gathers signals from your input, git history, and conversation context, then marks items complete, adds new items, logs decisions, and creates supporting artifacts in one pass.
/sombra:update batch 4 done, KR-6 cancelled — plumber unavailable
/sombra:update priorities shifted, AR-5 is now P0
/sombra:verify-distill — Verify a distilled contextScan a collection's distilled context, classify every substantive claim against the saved sources (anchored, loose, uncited), and walk through cleaning up the unsourced ones. Anchored and loose proposals are reviewed in the Sombra app; this skill handles the report and the unsourced-claim cleanup the app can't.
/sombra:verify-distill Lacinia GraphQL Reference
/sombra:research — Build a technical referenceDeep research on APIs, libraries, and frameworks. Saves sources to Sombra, distils them into a dense context document that any agent can load to write correct code without stale training data.
/sombra:research Pedestal HTTP routing
Each skill uses Sombra collections as the persistence layer:
Updates are surgical (replace_context_section) rather than full rewrites, so your documents stay clean as they evolve.
