Find the right tool. Automatically.
Semantic search across thousands of services. Auto-discovery when something is new.
SKB is the agent's skills library. Instead of pre-configuring every possible tool, agents describe what they need in plain language and SKB returns the exact capability — across Slack, Stripe, Salesforce, Notion, or a service nobody on your team has heard of yet. When a service is unknown, SKB learns it on demand from its public docs.
Semantic capability match
SKB embeds intent + capabilities and returns the best match by score and domain.
Why hard-coded tool lists break agents
The skills library is where most agent projects start to drift.
Every new tool needs OAuth setup, schemas, prompt examples, and tests. Six tools is a sprint; six hundred is a roadmap.
Rename a column, swap a provider, and a thousand prompts go stale at once. Drift is silent until something blows up in production.
If your agent says 'search Notion', migrating to Confluence is a rewrite. Tool names should not be load-bearing.
What SKB does
Four properties that make the skills library survive change.
Semantic capability search
pgvector + OpenAI embeddings match an intent like 'post to the team chat' to the right send_message capability — across Slack, Teams, Discord, or whatever the org actually uses.
LLM-assisted auto-discovery
When a service isn't yet in the catalog, SKB pulls its docs (including JS-heavy SPAs via the Playwright Renderer), extracts auth + endpoints + capabilities with Claude, and queues it for admin verification.
Domain tags survive tool swaps
Playbooks reference 'search document store', not 'search Notion'. Swap Notion for Confluence and the playbook keeps working — the binding happens at execution time against the org's actual SKB account.
Plays well with MCP
MCP servers light up alongside SKB connectors. The community ships breadth, SKB adds the semantic layer, domain tags, and credential isolation on top.
From intent to executed capability
How the skills library is queried in production.
Embed
The Orchestrator turns the agent's intent into an embedding.
Match
SKB returns the top-k capabilities by score, scoped to domain tags.
Discover
If nothing scores high enough, SKB launches discovery against public docs.
Verify
Auto-discovered services queue for admin review before they're trusted in agent runs.
