Machine-Readable Access

• Normalized dataset on GitHub: four explicit sets, provenance, loop ownership, feature evidence, official URLs, and dated GitHub metadata.
• Machine-readable reference guide: dataset contract, evidence states, rebuild commands, and maintenance rules.
• reference.yaml: stable routes to the engineering page, this landscape, product profiles, evaluation, observability, security, and release evidence.
• claude-code-releases.yaml: version-level evidence for Claude Code runtime behavior. It is release history, not a cross-product feature table.
• Best of Agent Harnesses site: upstream catalog and comparison guides.
• Pinned upstream JSON: the immutable source used for this snapshot.
• Upstream live JSON: useful for discovering changes after the pinned snapshot.
• MCP resource: claude-code-guide://agent-harnesses from this guide's MCP server.
• Upstream MCP package: agent-harnesses-mcp.

The refresh pipeline validates counts, URLs, evidence states, repository metadata, and deterministic output before it replaces the committed dataset. README extraction treats repository content as untrusted data and never publishes model output automatically.
