Sessions

Every session Glue runs is stored as plain text on your machine. No hosted dashboard, no telemetry upload, no agent ID tied to an account. The file is JSONL — one event per line, tail-able and grep-able.

Canonical sources:

• docs/reference/session-storage.md
• docs/reference/glue-home-layout.md

Where sessions live

~/.glue/sessions/<session-id>/
├── meta.json            # identity: model, provider, cwd, title, timestamps, git context
├── conversation.jsonl   # append-only event log
└── state.json           # session-scoped runtime state (Docker mounts, browser containers)

The <session-id> is a timestamp-based ID. Directories accumulate over time; prune old ones with rm -rf when you want the space back.

The event log

shipping Every event is one JSON object per line,

timestamped in UTC. Current event types:

• user_message — prompt you typed
• assistant_message — streamed model response
• tool_call — the agent invoked a tool (id, name, arguments)
• tool_result — result returned to the agent (call_id, content)
• title_generated — background title generation

An expanded event schema — covering tool state transitions, runtime events, file edits, and error details — is planned.

Example

{"schema_version":1,"event_id":"1740654600000-abc:1","session_id":"1740654600000-abc","sequence":1,"timestamp":"2026-04-19T10:30:00.000Z","type":"user_message","turn_id":"1740654600000-abc:turn:1","text":"explain the retry logic in http_client.dart"}
{"timestamp":"2026-04-19T10:30:00.420Z","type":"assistant_message","text":"Reading the file and the tests around it."}
{"timestamp":"2026-04-19T10:30:00.510Z","type":"tool_call","id":"t_1","name":"read","arguments":{"path":"packages/glue_strategies/lib/src/web/http_client.dart"}}
{"timestamp":"2026-04-19T10:30:00.630Z","type":"tool_result","call_id":"t_1","content":"…"}
{"timestamp":"2026-04-19T10:30:01.900Z","type":"title_generated","title":"HTTP client retry logic walkthrough"}

Resume

shipping Pass a session ID to continue where you

left off — the meta.json and conversation.jsonl are replayed back into the context window before the next prompt.

glue --resume

glue --resume <session-id>
glue --resume <session-id> "continue from here"

Replay UI

planned A dedicated replay surface that reads

conversation.jsonl and renders it step-by-step, with tool call collapse, diff rendering for file edits, and time scrubbing. Until it ships, any JSONL viewer works — the format is stable.

Why JSONL

• No vendor lock-in. The file is text. Any language can read it.
• Append-only. Crash-safe: a partial line at the tail doesn't corrupt earlier events.
• Debug-friendly. tail -f + jq is a reasonable observability stack for a local-first coding agent.
• Durable. Session history doesn't disappear because a hosted service rotated its database.

The simplification plan in the repo also removes the previous OTEL/Langfuse observability wiring. Sessions are the single durable log.
