Local Codebase Chat

The local-codebase application-state key is written by the Ask Plan browser folder picker when a user links a local codebase. It includes the selected folder name plus personal resource paths for the latest code index, file tree, and captured source snapshots.

The Ask Plan page can link a browser-selected local codebase folder. The UI indexes safe text files, skips generated/secret-looking paths, writes a small personal instruction resource under instructions/local-codebases/, and stores captured file snapshots under codebases/<id>/snapshots/<timestamp>/.
For live codebase questions, call view-screen when context is unclear and inspect localCodebase. First read its indexPath with the resources tool using scope: "personal", then read relevant captured file resourcePaths before making claims. Do not infer API contracts, schema shape, or UI behavior from file names alone.
If the file needed to answer is absent or skipped, ask the user to sync again or attach the file instead of guessing.
For API/schema/UI visualization from a local codebase, call get-plan-blocks or list-plan-components before visual-answer, then publish blocks such as openapi-spec, api-endpoint, data-model, diagram, file-tree, tabs, and annotated-code grounded in the files you read.
