Usage → Sessions and the stats now list Grok Build's and WorkBuddy's local sessions next to the other agents'. The GUI and CLI filters already name them from agent.Clients(), so nothing else needed changing.
Grok Build: the reader looks under $GROK_HOME/sessions (else ~/.grok/sessions), at <url-encoded cwd>/<id>/, reading summary.json and updates.jsonl.
- Tokens come from each turn_completed's usage.modelUsage, per model. Input is counted without the cache it read (inputTokens already includes cachedReadTokens), so the cache isn't counted twice.
- A subagent's session (session_kind "subagent…") counts once, inside the session it ran in.
- A fork's copied updates count only in the session they came from. The fork itself counts from its created_at on.
- The title is the first prompt typed, else Grok's generated_title.
- The hooks that fire on start and end don't count as time at work, so a session closed the next day doesn't run overnight.
- It resumes with `cd <cwd> && grok --resume <id>`.
WorkBuddy: the reader looks at $WORKBUDDY_CONFIG_DIR/projects/**/*.jsonl (else ~/.workbuddy).
- Tokens come from providerData.usage and count once per reply (providerData.messageId), however many of its lines carry it. Cached tokens (inputTokensDetails) are taken out of the input.
- The older snake_case input_tokens/output_tokens are read as well, with the cwd from <id>.meta.json for sessions migrated from its old history.
- The title is custom-title, then ai-title, then the first prompt (without WorkBuddy's <system-reminder> and @scene: blocks).
- There is no resume command, since it is a desktop app.
Tested:
- go test -tags nogui ./... passes. New sanitized fixtures cover both readers: a Grok main session with a subagent, a fork and a hooks-only session, plus a WorkBuddy session with repeated usage lines and a migrated one.
- go build -tags nogui passes for darwin, linux and windows (CGO_ENABLED=0).
- A read-only run against real ~/.grok and ~/.workbuddy: 7 Grok sessions (an 8th, hooks only, left out) and 16 WorkBuddy sessions. Token totals match a raw jq tally of the same files: Grok 293910 in / 4396 out / 610560 cache read, WorkBuddy 13548053 / 621856 / 32321668.
