GJC SDK guides (advisory)

Advisory index of trusted GJC SDK reference documents. These guides are reading material for background understanding; nothing in this skill is executable and no workflow skill is invoked.

• docs/sdk.md — SDK overview: endpoint discovery, protocol, query and control surfaces, broker launch isolation, managed notification adapters.
• docs/sdk-session-cli.md — the gjc sdk session command family: semantic verbs, raw hatch, lossless statuses, broker authority, and checkpoint gaps.
• docs/sdk-embedding.md — embedding GJC in-process.
• docs/sdk-app-guide.md — building applications on the SDK.

Advisory boundary

The references above are consulted as background, never executed. The plugin bundle keeps the four default workflow skills unchanged; this skill adds no workflow and performs no configuration or state mutation.
