Lists multiple specific concrete actions: 'Deploy sites', 'configure serverless and edge functions', and 'verify builds on Netlify'. These are distinct, actionable capabilities.

Clearly answers both 'what' (deploy sites, configure functions, verify builds) and 'when' (explicit 'Use when...' clause with trigger terms and a separate trigger terms list).

Includes strong natural keywords users would say: 'deploy preview', 'netlify.toml', 'build error', 'Netlify Functions', 'deploy logs', 'failed deploy'. These cover common variations of how users would describe Netlify-related tasks.

Clearly scoped to Netlify specifically, with platform-specific triggers like 'netlify.toml', 'Netlify Functions', and 'deploy preview'. Unlikely to conflict with generic deployment or other hosting platform skills.

The content is lean and efficient. It avoids explaining what Netlify is or how serverless functions work conceptually. Every section delivers specific configuration, commands, or code examples without padding.

Provides fully executable code examples (netlify.toml config, TypeScript edge/scheduled functions), specific CLI commands for building and debugging, and concrete curl commands for verification. All examples are copy-paste ready.

The deployment workflow is clearly sequenced (configure → build locally → push → verify → merge) with explicit validation checkpoints: local build with --debug before pushing, curl verification after deploy, and a feedback loop (inspect logs, fix, re-deploy) for failures.

References to REFERENCE.md and deployment-config.md are well-signaled and one level deep, which is good structure. However, no bundle files were provided, so REFERENCE.md doesn't actually exist, making these references unverifiable. The inline content is appropriately scoped but some sections (security headers, env var scoping, extended verification scripts) are deferred to a non-existent file.
