Adds a provider skill covering Linear's `Linear-Signature` HMAC-SHA256 verification (hex, no prefix), `webhookTimestamp` replay protection, and Issue / Comment / Project / Cycle / IssueLabel / IssueSLA event routing with Express, Next.js App Router, and FastAPI examples.
Adds the Linear row to the Provider Skills table in README.md and a providers.yaml entry (docs URLs, notes, testScenario) so the "Validate New Provider" CI workflow finds the integration files. The integrations were previously only on the prep branch (PR #40); moving them onto each feat PR makes the 12 generated PRs independently mergeable in any order. https://claude.ai/code/session_01NNTgQRJss1V7gyzzJ9rjnB
…ce arg Applies the new project convention from PR #40: use `npx hookdeck-cli listen <port> <source> --path /webhooks/<source>` everywhere instead of `hookdeck listen <port> --path /webhooks/<source>`. Skips the global-install prereq (webhook-skills is provider-neutral) and passes the required `[source]` positional so the command is copy-paste- runnable without falling into an interactive prompt. https://claude.ai/code/session_01NNTgQRJss1V7gyzzJ9rjnB
