Runtime reference
Devin#
ClawMetry reads the Devin CLI, which keeps every session in a local SQLite database. Devin Cloud sessions are reachable only through an authenticated vendor API and are deliberately out of scope — a local-first observer should not be making authenticated egress calls with your enterprise key.

Where the data comes from#
ClawMetry reads these locations, in order, and never writes to any of them.
$XDG_DATA_HOME/devin/cli/sessions.db (default ~/.local/share/devin/cli)$XDG_DATA_HOME/devin/cli/logs/devin_<ts>_<pid>.log
Format. One SQLite database holding every session: sessions, message_nodes (a forest, not a list) and tool_call_state.
Environment variables#
| Variable | Effect |
|---|---|
CLAWMETRY_DEVIN_DB | point at a specific sessions.db |
CLAWMETRY_DEVIN_HOME | home override |
XDG_DATA_HOME | honoured for the default path |
See Environment variables for the variables that apply to every runtime.
Tokens and cost#
Tokens. On the message metadata: num_tokens, plus committed ACU and credit cost.
Cost. Committed ACU / credit cost per message, summed over the active chain only.
Why this section exists
Runtimes differ enormously in what they persist. Rather than showing a plausible number everywhere, ClawMetry reports what the store actually contains and marks the rest unknown. A cost of $0.00 and a cost of unknown mean different things, and the dashboard keeps them different.
Things worth knowing#
message_nodesis a forest:/forkand/revertleave abandoned turns in place as sibling branches. Summing every row bills you for work you threw away, so ClawMetry walks the active chain frommain_chain_idand reports the abandoned nodes as a count./rm-sessionsetshidden=1instead of deleting. Those stay out of the list — a session you deleted should not be resurrected.- Devin Desktop (formerly Windsurf) never writes Cascade sessions to disk, so there is nothing local to read. It is not this adapter.
Verify it is being read#
# Is this runtime detected, and would this install unlock it?
clawmetry runtimes --json | jq '.runtimes[] | select(.id=="devin")'
# Why is it locked, if it is?
clawmetry runtimes --why devin
# Any sessions ingested yet?
curl -s 'http://localhost:8900/api/local/sessions?limit=5' \
| jq '.rows[] | {session_id, agent_id, events, cost_usd}'If detection succeeds but no sessions appear, work through Troubleshooting — the usual causes are a relocated data directory (set the override above), a session limit that is hiding older runs, or a runtime that simply has not written anything yet.
