inference-gateway/adk

Skill Claude CodeCodex

Idiomatic Go concurrency - sync primitives, channel semantics, the select statement, and the standard channel patterns (cancellation/done-channel, fan-out/fan-in, pipeline, or-done, context, worker-pool). Use when writing or reviewing Go that spawns goroutines, shares state, or coordinates over channels, even if the…

inference-gateway/adk

Skill Claude CodeCodex

Review a Go design spec before implementation begins - dispatch a subagent that checks a design doc for completeness, consistency, and idiomatic Go (simplicity, small consumer-defined interfaces, explicit wrapped errors, context propagation). Use when a user has a Go spec to review, asks "is this spec ready?", or is…

inference-gateway/adk

Skill Claude CodeCodex

Idiomatic Go - package and interface design, error wrapping, table-driven tests, generics, the modern standard library (slices/maps/cmp/errors.Join), current syntax, and logging discipline. Use when writing, reviewing, or refactoring any Go code, especially code drifting toward Java/Spring shapes (deep layer trees…

Knuckles-Team/searxng-mcp

Skill Claude CodeCodex

Persist SearXNG search results into the epistemic-graph knowledge graph via the searxng-mcp MCP server. Use when the agent must turn a web search into durable, semantically-searchable KG memory — each result becomes a :Document (plus :SearchQuery and :SearchEngine typed nodes with :resultOf / :fromEngine links) so…

Knuckles-Team/searxng-mcp

Skill Claude CodeCodex

Inspect and edit the EMBEDDED SearXNG instance's settings.yml (the private, loopback-only, zero-config search fallback the searxng-mcp server can own end to end when no external SEARXNGURL is configured). Use when the agent or operator wants to change what the embedded instance does — enable/ disable formats, flip…

Knuckles-Team/searxng-mcp

Skill Claude CodeCodex

Privacy-respecting web metasearch via the searxng-mcp MCP server. Use when the agent needs current, open-web results for a query and must NOT leak the query to a single tracking engine — SearXNG aggregates many engines (Google, Bing, DuckDuckGo, Wikipedia, …) behind one JSON tool. Use for general lookups…

Knuckles-Team/jellyfin-mcp

Skill Claude CodeCodex

Natively ingest a Jellyfin library into the epistemic-graph knowledge graph via the jellyfin-mcp MCP server — push library items as typed :MediaAsset/:Book nodes with :hasGenre/:performedBy/:authoredBy links and item overviews as searchable :Document nodes (jellyfiningestlibrary), and item posters as content-addressed…

Knuckles-Team/jellyfin-mcp

Skill Claude CodeCodex

Browse and search a Jellyfin media library via the jellyfin-mcp MCP server — list library items (movies, series, episodes, audio, books), fetch one item by id, walk collections and user views, and run search hints with the domain-typed jellyfinlibrary tool. Use when the agent must find or enumerate catalog items…

Knuckles-Team/jellyfin-mcp

Skill Claude CodeCodex

Stream and control Jellyfin playback and browse music via the jellyfin-mcp MCP server — list artists, albums, and music genres, resolve audio/video streams, manage playlists, and drive playstate (play, mark played, report progress) with the domain-typed jellyfinmedia tool. Use when the agent must start or control…

Knuckles-Team/documentdb-mcp

Skill Claude CodeCodex

Read-only analytics on a DocumentDB (MongoDB-compatible, PostgreSQL-backed) collection via the documentdb-mcp MCP server — run aggregation pipelines ($match/$group/$sort/…) and fetch distinct field values. Use when the agent must summarize, group, or profile documents rather than fetch individual rows. Do NOT use for…

Knuckles-Team/documentdb-mcp

Skill Claude CodeCodex

Database, collection, and user administration on a DocumentDB (MongoDB-compatible, PostgreSQL-backed) server via the documentdb-mcp MCP server — list/create/drop/rename databases and collections, and manage database users and their roles. Use when the agent must provision or tear down namespaces, enumerate the…

Knuckles-Team/documentdb-mcp

Skill Claude CodeCodex

Document create/read/update/delete operations on a DocumentDB (MongoDB-compatible, PostgreSQL-backed) collection via the documentdb-mcp MCP server — insert one/many, find with filter/sort/skip/limit, update/replace one/many, delete, count, and the atomic find-and-modify variants. Use when the agent must read or mutate…

Knuckles-Team/archivebox-api

Skill Claude CodeCodex

Natively ingest an ArchiveBox archive into the epistemic-graph knowledge graph via the archivebox-api MCP server — push snapshots as typed :Snapshot nodes (with :Tag + :hasTag links and per-snapshot :Document page-text) and archive results as :ArchiveResult nodes, best-effort, with the Wire-First ingest tools. Use…

Knuckles-Team/archivebox-api

Skill Claude CodeCodex

Browse and search an ArchiveBox archive via the archivebox-api MCP server — list/filter snapshots, read one snapshot (with its per-extractor archive results), list archive results by extractor/status, and read tags with the domain-typed core tool. Use when the agent must find an archived URL, inspect what was captured…

Knuckles-Team/archivebox-api

Skill Claude CodeCodex

Capture and re-archive web pages with ArchiveBox via the archivebox-api MCP server — add URLs (with tags, crawl depth, and chosen extractors), update / re-archive existing snapshots, and schedule recurring archiving with the domain-typed CLI tool. Use when the agent must permanently archive a URL, bulk-add a list of…
