Runtime reference

Cline#

Cline records more than any other runtime ClawMetry reads: a SQLite session index with pid, status and exit code, dollars on disk, the per-message token split, real schedules with per-run cost, and — uniquely — the tool calls the model emitted that Cline itself rejected.

Where the data comes from#

ClawMetry reads these locations, in order, and never writes to any of them.

  • <data-dir>/db/sessions.db — session index
  • <data-dir>/sessions/<sid>/<sid>.json — per-session sidecar
  • <data-dir>/sessions/<sid>/<sid>.messages.json — the transcript

Format. SQLite index plus one JSON transcript per session; content blocks are Anthropic-shaped whichever provider actually ran.

Environment variables#

VariableEffect
CLINE_DATA_DIRCline's own data-dir env
CLINE_DIRolder spelling, also honoured
CLAWMETRY_CLINE_DATA_DIRClawMetry-side override

See Environment variables for the variables that apply to every runtime.

Tokens and cost#

Tokens. Real, per message, including cache reads and writes.

Cost. Real dollars on disk at metadata.usage.totalCost.

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.

Sub-agents and delegation#

Full lineage in the index: parent_session_id, agent_id and is_subagent columns.

Things worth knowing#

  • The default data dir is ~/.cline/**data**. ~/.cline itself holds hooks/ and worktrees/ — pointing at it finds nothing.
  • Per-message metrics and the sidecar totalCost are both authoritative and must not be added together.
  • metadata.invalidToolCalls records calls Cline rejected. It is a direct signal of a model that cannot drive its tools, and nothing else in the matrix admits its own failures.

Verify it is being read#

bash
# Is this runtime detected, and would this install unlock it?
clawmetry runtimes --json | jq '.runtimes[] | select(.id=="cline")'

# Why is it locked, if it is?
clawmetry runtimes --why cline

# 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.
