-## Why KTX
+## Why KTX helps
 
-- Schemas show columns, not business rules.
-- Agents need trusted metrics, joins, filters, caveats, and provenance.
-- KTX captures that context before agents write SQL, docs, or semantic edits.
+KTX gives agents a shared context workspace before they write SQL, answer a
+question, or update analytics definitions.
 
-## What KTX creates
+- **Context as code.** KTX writes wiki pages and semantic-layer definitions as
+  git-based files you can review, diff, and merge.
+- **Self-improving ingest.** KTX reads warehouses, BI tools, modeling code,
+  query history, and notes, then reconciles new evidence with accepted context.
+- **Executable semantics.** Agents can use approved measures, joins, filters,
+  dimensions, and segments instead of rebuilding canonical SQL from scratch.
+- **Agent-native access.** CLI and MCP tools let agents search context, compile
+  semantic queries, run read-only SQL, and propose updates.
 
-KTX ingestion turns source evidence into durable context files that agents can
-search, review, and execute.
+KTX complements existing semantic layers by pairing metric definitions with the
+surrounding business knowledge, caveats, provenance, and review workflow agents
+need for data work.
 
-| Path | What it gives agents |
-|------|----------------------|
-| `semantic-layer/` | Executable measures, dimensions, joins, grain, filters, and segments |
-| `wiki/` | Business definitions, caveats, policies, analyst notes |
+## How KTX works
+
+KTX has two connected sides: it builds and maintains the context layer, then
+serves that context to agents at runtime.
+
+| Side | What KTX does |
+|------|---------------|
+| **Ingest and auto-maintain knowledge** | Reads your data stack and company knowledge, reconciles new evidence with accepted context, and keeps changes to `semantic-layer/` plus `wiki/` as version-controlled diffs automatically. |
+| **Serve agents at runtime** | Helps agents find the right wiki pages and semantic-layer entities, then compile or execute semantic queries through CLI and MCP tools. |

 ## Use it for
 
-- **Generate SQL** from approved measures, dimensions, joins, and filters
-- **Explain provenance** with wiki context and warehouse evidence
-- **Repair context** through reviewable YAML and Markdown diffs
-- **Work alongside** dbt, LookML, MetricFlow, Looker, Metabase, and warehouses
+Use KTX when agents need more than raw database access. Agents can search wiki
+context, find semantic-layer entities, compile trusted semantic queries, run
+read-only SQL, and use the same tools through MCP.
 
-Databases: SQLite, PostgreSQL, Snowflake, BigQuery, ClickHouse, MySQL, SQL
