Decode hex-encoded Claude Code Keychain credentials - #1
Merged
Conversation
Claude Code 2.1.x stores the Keychain item as hex JSON. Parsing it as UTF-8 JSON failed and skipped ~/.claude/.credentials.json, so usage limits reported unauthenticated while the CLI was logged in.

What was wrong
Claude Code 2.1.x stores the macOS Keychain item
Claude Code-credentialsas hex-encoded JSON (7b…is{). bb parsed that blob as UTF-8 JSON, failed, and treated a non-empty Keychain read as success, so it never opened~/.claude/.credentials.json. Settings → Usage limits then showed Claude asunauthenticatedwith empty windows even though the CLI was logged in.This is base bb (
plugins/provider-claude-code), not the community Usage plugin. The plugin only rendersGET /api/v1/system/usage-limits.Related: get-bb/bb#2928.
What changed
decodeCredentialBlobhex-decodes, then JSON-parses.HOST_DAEMON_PROTOCOL_VERSIONbump.Why this way
The empty-windows symptom looked like a User-Agent or
weekly_scopedparser bug. The actual failure was earlier: we never sent a token. Decode-then-file-fallback is the smallest change that makes an already-valid login visible.UA / percent / camelCase window keys / model-scoped caps (Fable) are a separate parser change in the same file. They stay out of this PR so a credentials bug is not mixed with a response-mapping change.
Benefit to bb
Every Mac user on Claude Code 2.1.x. Usage limits (and any
provider.usageclient) show the same session/weekly windows the CLI shows. No daemon update.Harvest
Independent. Already opened: get-bb/bb#2931 Fixes get-bb#2928.
Decision record: docs/perf-control-plane.md (PR #9).
